                 FLAMMARION'S POPULAR ASTRONOMY

     Translated from the French by J. ELLARD GORE, F.R.A.S.
              With 3 Plates and 288 Illustrations.

     "The six books into which the book is divided give a very
     lucid and accurate description of the knowledge which has
     been acquired of the moving bodies of space, both as respects
     their motions and physical constitutions. Of the translation
     we can only speak in terms of praise. Not only does it well
     represent the original, but Mr. Gore has added useful notes
     for the purpose of bringing the information up to date, and
     has also increased the number--already very considerable--of
     the excellent illustrations, so that the work is likely to
     become as popular in England as it has been in
     France."--ATHENÆUM.

     "The work which Mr. J. E. Gore has translated into English
     has made for itself a name and reputation in France ... and
     has gone into general circulation to the number of a hundred
     thousand copies. This last fact is proof how well within the
     bounds of possibility it is to make the latest discoveries of
     science comprehensible and fascinating to the common mind. M.
     Flammarion has attained this triumph through the grasp of his
     knowledge, the lucidity of his style, and his power of
     bringing home the most stupendous and complicated of the
     things revealed to us in the depths of space. M. Flammarion's
     pages should find almost as great acceptance in this country
     as in his own. Simplicity of arrangement and of statement are
     part of his charm and of his success."--SCOTSMAN.

     "M. Flammarion's latest volume, if it does not displace its
     English rivals, may well take a high place in the rank to
     which they belong. It is full, lucid, and, thanks to Mr.
     Gore's careful revision, well up to date.... Mr. Gore's
     edition is so carefully brought abreast of the latest
     discoveries that the English student may now congratulate
     himself on being in an even better position than the
     countrymen of M. Flammarion."--DAILY CHRONICLE.

     "Young students of astronomy who wish to obtain a general
     idea of the most wonderful and fascinating of all sciences
     will find precisely what they seek in M. Flammarion's
     eloquent and poetic chapters.... There are many illustrations
     in this able and attractive treatise."--SPEAKER.

     "It is a fascinating work, extending to nearly seven hundred
     pages, and dealing in popular language with some of the most
     interesting of the discoveries and speculations of
     astronomers."--DAILY NEWS.

     "M. Flammarion is a sound practical astronomer; he has
     rendered good and laborious service to the science, and he
     possesses a valuable faculty of popular exposition.... The
     volume is profusely and well illustrated, some of the best
     plates making here their first appearance."--SATURDAY REVIEW.

     "A high place must be accorded to Flammarion's 'Popular
     Astronomy.' Never before has the science of the heavens been
     treated with such fulness and interest as in this fascinating
     book; for Flammarion is a man of letters as well as a man of
     science--a man of letters, too, endowed with the wondrous
     gifts of lucidity and charm which distinguish the best French
     writers.... Flammarion's book is much more absorbing than
     most novels, more romantic than most romances, more poetic
     than most poems, yet strictly and scientifically
     accurate."--LUDGATE MONTHLY.

     "It must be confessed that M. Flammarion not only arrests the
     attention, but assists the reader to grasp astronomical
     theories--a task in which less popular writers often fail
     when they make the attempt."--LITERARY WORLD.

     "The book is a most fascinating one, and holds the reader
     from start to finish.... As a manual for those who wish to
     obtain a good general knowledge of astronomy this work will
     be found unsurpassed."--SCIENCE GOSSIP.

THUNDER AND LIGHTNING



CHAPTER I

THE VICTIMS OF LIGHTNING


It would be an interesting thing to make a careful study once a year,
towards the end of the summer, of the habits and customs of thunder
and lightning. Perhaps in this way we should succeed one day in
determining the still mysterious nature of these elusive forces. I,
for my part, have been engaged upon the task for many years past. It
has produced a big accumulation of records, and in this volume I can
find room but for a _résumé_ of them, as varied as possible. In my
first chapter I shall present a few characteristic examples, just to
give my readers some hint of this variety.

Not to go too far back, let us begin with a harmless--I might almost
say playful--fireball performance, of which M. Schnaufer, Professor at
Marseilles, has given me the particulars.

In October, 1898, the fireball in question made its appearance in a
room and advanced towards a young girl who was seated at the table,
her feet hanging down without touching the floor. The luminous globe
moved along the floor in the girl's direction, began to rise quite
near her and then round and round her, spiral fashion, darted off
towards a hole in the chimney--a hole made for the stove-pipe, and
closed up with glued paper--made its way up the chimney, and, on
emerging into the open air, gave out upon the roof an appalling crash
which shook the entire house. It was a case of coming in like a lamb
and going out like a lion!

A similar occurrence is recorded as having been observed in Paris, on
July 5, 1852, in a tailor's room, including the same curious detail of
the departure through the hole in the chimney, closed up with paper.

It was in the Rue Saint Jacques, near the Val de Grâce. The fireball
burst into the room from the chimney, knocking over the paper guard in
front of the fireplace. In appearance it suggested a young cat,
gathered up into a ball, as it were, and moving along without using
its paws. It approached the tailor's legs as though to play with them.
The tailor moved them away to avoid the contact, of which he naturally
was in terror. After some seconds, the globe of fire rose vertically
to the height of the man's face as he sat, and he, to save himself,
leaned quickly back and fell over. The fireball continued to rise,
and made its way towards a hole which had been made at the top of the
chimney for the insertion of a stove-pipe in the winter, but which, as
the tailor put it afterwards, "the fireball couldn't see," because it
was closed up with paper. The ball stripped off the paper neatly,
entered the chimney quite quietly, and having risen to the summit,
produced a tremendous explosion, which sent the chimney-top flying,
and scattered it in bits all over the neighbouring courtyard and
surrounding roofs.

There we have a unique occurrence, recorded for us by Babinet and
Arago, and of which I have given here the exact particulars. In both
these cases we have to note the attraction of the hole in the chimney
and the explosion of the thunderbolt on getting to the top. But it is
not easy to detect the law underlying these phenomena.

In one of the latest volumes of the Association Française a somewhat
similar case is dealt with.

"A violent storm," says the writer, M. Wander, "had descended upon the
commune of Beugnon (Deux-Sèvres). I happened to be passing through a
farm, in which were two children of about twelve and thirteen. These
children were taking refuge from the rain under the door of a stable,
in which were twenty-five oxen. In front of them extended a
courtyard, sloping downwards towards a large pond, twenty or thirty
yards away, beside which grew a poplar-tree. Suddenly there appeared a
globe of fire, of the size of an apple, near the top of the poplar. We
saw it descend, branch by branch, and then down the trunk. It moved
along the courtyard _very slowly_, seeming almost to pick its way
between the pools of water, and came up to the door where stood the
children. One of them was bold enough to touch it with his foot.
Immediately a terrible crash shook the entire farm to its foundations,
the two children were thrown to the ground uninjured, but eleven of
the animals in the stable were killed!"

Who is to explain these anomalies? The child who touched the fireball
escapes with a fright, and a few feet behind him eleven animals out of
twenty-five perish on the spot!

During the storm which broke out at the town of Gray, on July 7, 1886,
my friend M. Vannesson, President of the Tribunal, saw a fireball of
from thirty to forty centimetres in diameter, which exploded on the
corner of a roof, cutting clean off the end portion of the central
beam to the length of about half a yard (like a bundle of matches, but
without setting it on fire), scattering the splinters over the upper
story and loosening the plaster upon the walls below. It then
_rebounded_ on the roofing of a little outside staircase, made a hole
in it, smashing and sending flying the slates, came down upon the
road, and rolling right in the midst of some passers-by--who, like the
child in the farm, escaped with a fright--disappeared.

My learned fellow-member of the Astronomical Society of France, Dr.
Bougon, has discovered an account of one of the most remarkable
fireballs ever recorded in _La Gloire des Confesseurs_, a work written
by Gregory of Tours, the twentieth bishop of that town.

On the dedication day of an oratory which he had constructed in one of
the outer buildings of the episcopal palace, all the participants in
the procession from the cathedral, while approaching the oratory with
the sacred relics and singing the litanies, saw a globe of fire, so
intensely brilliant that their eyes were dazzled, and they could
scarcely keep them open. Seized with terror, priests, deacons,
sub-deacons, choristers, together with the distinguished citizens of
the town, who were carrying the relics upon their shoulders, all with
one accord threw themselves on the ground, face downward. Then
Gregory, remembering that on the occasion of the death of St. Martin,
some of whose bones were among the relics being carried from the
cathedral, a globe of fire was said to have been observed to leave the
saint's head and ascend heavenwards, believed himself to be in the
presence of a miracle, vouchsafed as evidence at once of St. Martin's
sanctity and the genuineness of his relics. This globe of fire did no
damage and burnt nothing. _Discurrebat autem per totam cellulam_,
TANQUAM FULGUR, _globus igneus_.

There is to be seen at the Louvre a picture by Eustache Lesueur,
entitled "La Messe de Saint Martin," which seemed to me at first to
illustrate this narrative, but the spectators are shown in silent
wonder instead of being prostrated as in the story. Moreover, Gregory
of Tours tells us in his life of St. Martin, that one day during Mass
a globe of fire was seen to appear above the head of the bishop, and
then to rise heavenwards, to the great edification of the devout. It
was this "miracle," evidently, that Lesueur intended to represent.

Here is another case of a remarkably harmless fireball which is often
cited.

The Abbé Spallanzani it is who tells the story. On August 29, 1791, a
young peasant woman was in a field during a storm, when suddenly there
appeared at her feet a globe of fire of about the size of a billiard
ball. Slipping along the ground, this little fireball reached her
feet, caressed them, as it were, made its way up under her clothes,
and issued again from the middle of her bodice, and, still keeping its
globular form, darted off into the air and exploded noisily. When it
got under her petticoats, they blew out like an umbrella, and she fell
back. Two witnesses of the scene ran to her assistance, but she was
unhurt. A medical examination revealed only a slight erosion of the
skin, extending from the right knee to the middle of her breast; her
chemise had been torn in two along the same line, and there was a hole
through her bodice where the thunderbolt had got out.

In the "Memoirs of Du Bellay" the following very curious narrative is
to be found. In all probability it is a fireball that is in
question:--

"On March 3, 1557, Diane of France, illegitimate daughter of Henri
II., then the Dauphin, married François de Montmorency. On the night
of their wedding, an oscillating flame came into their bedroom through
the window, went from corner to corner, and finally to the nuptial
bed, where it burnt Diane's hair and night attire. It did them no
other harm, but their terror can be imagined."

Perhaps it may be as well to take with a pinch of salt the statement
that the lady's attire was burnt in this way without harm to her
person, yet there are other authentic stories of a similar kind almost
as curious.

In 1897, at Linguy (Eure-et-Loire), a man and his wife were sleeping
quietly, when suddenly a terrible crash made them jump out of bed.
They thought their last hour had come. The chimney, broken to pieces,
had fallen in and its wreckage filled the room, the gable-end was put
out and the roof threatened to come down. The effects of the
thunderbolt in the room itself were less alarming than its effects
outside, but were very curious. For instance, bricks from one wall had
been dashed horizontally against the wall opposite, with such
extraordinary force that they were to be seen imbedded in it up above
a dresser upon which pots and pans, etc., were ranged, and within a
few inches of the ceiling, while the windows of the room had been
smashed into bits, and a looking-glass, detached from the wall, stood
on end whole and entire upon the floor, delicately balanced. A chair
near the bed, upon which articles of clothing had been placed, had
been spirited away to a spot near the door. A small lamp and a box of
matches were to be found undamaged upon the floor. An old gun,
suspended from a beam, was violently shaken and had lost its ramrod.

The thunderbolt actually frolicked over the bed, leaving its occupants
more dead than alive from terror but quite unhurt. It passed within a
few inches of their heads and passed through a fissure in a partition
into an adjoining dairy, where it carried a whole row of milk-cans,
full of milk, from one side of the room to another, breaking the lids
but not upsetting a single can. It broke four plates out of a pile of
a dozen, leaving the remaining eight intact. It carried away the tap
from a small barrel of wine, which emptied itself in consequence.

It ended by passing out through the window without further breakage,
leaving the husband and wife unscathed but panic-stricken.

One of the strangest tricks to which lightning is addicted is that of
undressing its victims. It displays much more skill and cleverness in
such diversions than is to be found in animals or even in many human
beings.

Here is one of the most curious instances of this on record, as
narrated by Morand:--

"A woman in man's costume. A storm suddenly comes on. A flash of
lightning strikes her, carries off and destroys her clothes and boots.
She is left stark naked, and she has to be wrapped up in a cloth and
taken thus to the neighbouring village."

In 1898, at Courcelles-les-Sens, Mlles. Philomène Escalbert, aged 19,
Adèle Delauffre, aged 22, and Madame Léonie Legère, aged 44, were
standing round a reaping-machine, when a flash of lightning struck
Madame Legère and killed her on the spot. The two young girls were
stripped to the skin, even their boots being torn from their feet.
Otherwise they were left safe and sound--and astonished.

On October 1, 1868, seven persons took refuge during a storm under a
huge ash-tree near the village of Bonello, in the Commune of Perret
(Côtes-du-Nord), when suddenly the tree was struck by lightning, and
one of them--a woman--was killed. The six others were knocked to the
ground without being seriously damaged. The clothes of the woman who
had been killed were torn into shreds, many of which were found
clinging to the branches of the tree.

On May 11, 1869, a farmer at Ardillats was tilling the ground with his
two oxen, not far from his dwelling-place, about four in the
afternoon. The air was close and heavy, and the sky covered with black
clouds. Suddenly there was a great thunderclap, and a flash of
lightning struck both man and beasts dead on the spot. The man was
found stripped to the skin, and his boots had been carried thirty
yards away.

In July, 1896, at Epervans (Saône-et-Loire), a young man named Petiot,
who was mowing in a meadow, was struck dead by lightning while
lighting a cigarette, and left in a state of complete nakedness.

On August 11, 1855, a man was struck by lightning near Vallerois
(Haute-Saône), and stripped naked. All that could be found afterwards
of his clothes was a shirt-sleeve, a few other shreds, and some pieces
of his hobnailed boots. Ten minutes after he was struck he regained
consciousness, opened his eyes, complained of the cold, and inquired
how he happened to be naked.

There is no telling what lightning will not do.

Sometimes it will snatch things out of your hand and carry them right
away.

There is a case of a mug being thus spirited away from a man, who had
just been drinking out of it, and deposited undamaged in a courtyard
near--the man himself suffering no injury. A youth of eighteen,
holding up a missal from which he is singing, has it torn out of his
hands and destroyed. A whip is whisked out of a rider's hand. Two
ladies, quietly knitting, have their knitting-needles stolen. A girl
was sitting at her sewing-machine, a pair of scissors in her hand; a
flash of lightning, and her scissors are gone and she is sitting _on_
the sewing-machine. A farmer's labourer is carrying a pitchfork on his
shoulder; the lightning seizes it, carries it off fifty yards or so,
and twists its two prongs into corkscrews.

On July 22, 1878, at Gien (Nievre), a woman while sprinkling her house
with holy water during a storm, saw her holy-water bottle smashed
actually in her fingers by the lightning, which at the same time
smashed up the tiled pavement of the room.

In a church at Dancé (Loire) during vespers, one day in June, 1866, a
flash of lightning killed the priest and all the congregation, knocked
over the monstrance on the altar, and buried the Host in a heap of
_débris_.

On June 28, 1885, the cupola of the Javisy Observatory, which was not
then provided with a lightning conductor, was struck by lightning. An
enormous piece of oak from _un angle de construction_ was torn to
shreds, and one splinter was lodged in the hinge of a window behind
the _pivot_, in the part between the _pivot_ and the frame, hardly a
twenty-fifth of an inch apart, and this without breaking the glass.

In other cases lightning has been known to split men in two, almost as
with a huge axe. On January 20, 1868, this happened to a miller's
assistant in a windmill at Groix. The lightning struck him, and split
him from his head downwards in two.

In the course of July, 1844, four inhabitants of Heiltz-le-Maurupt,
near Vitry-le-Françoise, took refuge under trees during a storm, three
of them under a poplar, and the fourth under a willow, against which
doubtless he leaned. In a few minutes this one was struck by
lightning. A bright flame was observed to be issuing from his clothes,
but he remained standing, and seemed unconscious of what had happened.
"You're on fire! You're on fire!" exclaimed his friends. Getting no
reply, they went up to where he was, and found to their horror that he
was a corpse.

A clergyman named Butler was a witness of the following incident,
which took place at Everdon. Ten harvest-men took refuge under a lodge
on the approach of a storm. There was a thunderclap, and in a moment
four of them were killed by lightning. One of them was found dead,
still holding between finger and thumb a pinch of snuff he had been in
the act of taking. A second had one hand upon the head of a small dog,
also killed, and still sitting upon his knees, and in the other hand a
piece of bread; a third was sitting, his eyes open, facing in the
direction from which the storm came.

At Castellane, in August, 1898, during a violent storm, a flock of
sheep was struck by lightning while crossing the mountain of Peyresy.
Seventy-five of them were killed. The shepherd escaped. The sheep
probably were all wet from the rain, and clinging together in one
great mass. In the same month a pond at Vauxdîmes (Côte-d'Or) was
demolished, and all the fish in it killed.

Quite recently, a young man at Franxault (Côte-d'Or) was killed by
lightning on his way home from work. All the nails were found to have
been torn out of his shoes, and the links of his silver watch-chain
were all moulded together. To fuse silver in this way a heat of 957
degrees is needed!

On July 5, 1883, at Buffon (Côte-d'Or), a woman had one of her
earrings melted in the same way, but she was not killed. On the same
day at Void (Meuse) two workmen, who had taken shelter under a willow,
were thrown a distance of four yards without being killed.

On August 10, of the same year, at Chanvres (Yonne), a vine-dresser
was struck by lightning and killed, but his heart continued to beat
for thirty hours.

Dr. Gaultier de Claubry was struck by lightning, with the
extraordinary result that his beard was taken off him, roots and all,
so that it never grew again.

At Fresneaux (Oise), a young girl of twenty, Mlle. Laure Leloup, had
her head shorn by lightning. A wide furrow was to be traced on the
crown of her head, caused by the electric fluid. Her hair was removed
right down to the skin as though by a razor.

On September 4, 1898, a flash of lightning lit up all the electric
lamps in the Prefecture of Lyon.

Really it is extraordinary the queer things lightning will do! Death
in one case, an innocent practical joke in another! I have hundreds of
quaint records before me. Impossible to deduce any kind of law from
them all. You are tempted to believe that the electric current has a
brain.

A young woman was picking cherries off a rather tall cherry-tree. A
young man stood underneath. The young woman was struck by lightning,
and fell dead. This was in July, 1885.

In September, 1898, at Remaines, near Ramerupt (Aube), a certain M.
Finot, an innkeeper, was standing on his doorstep looking out at a
storm, when a flash of lightning followed by a thunderclap sent him
flying back into the hall. He remained unconscious for a time, and
his sight was affected for ten hours. The extraordinary thing,
however, in his case was that he had been a victim of rheumatism until
then, and walked with difficulty and only with a stick, and that ever
since this occurrence he has been able to do without the stick, and to
pursue his avocations quite comfortably. He feels that he has no
reason to regret his experience, though he is not anxious to go
through anything of the kind again. This kind of electrical phenomenon
might be catalogued under the title "Medicinal Lightning."

Now for a case of "Judicial Lightning."

On July 20, 1872, a negro named Norris was hanged in the State of
Kentucky for having killed a mulatto, a fellow-workman of his. At the
moment of his setting foot upon the scaffold, there was a terrible
clap of thunder, and the condemned man was struck dead by lightning.
The sheriff was so much moved by the occurrence that he resigned his
office.

Let us wind up this little collection of strange cases with another
occurrence reported from the United States.

An immense grange had been built by a man named Abner Millikan, an
ardent republican, who adorned the front walls of his farm with
portraits of MacKinley and Hobart. During a violent storm that broke
out, the building was struck by lightning several times, and it
looked as though it were enveloped in great sheets of flame. Millikan,
who had been at some distance from the spot, rushed thither much
alarmed, and found to his relief that no damage had been done. The
portraits alone had been destroyed, and--here is the strange
detail--the lightning had traced the politicians' features upon the
wall.

Certainly lightning plays queer pranks. And I have said nothing yet of
the photographs lightning sometimes takes.

_Pranks_ they seem to us, but we may be sure there is some method in
their mischievousness. It is the same with women. Women in their
caprices are but obeying some law of nature. They are not so
capricious as they seem.

These strange facts teach us, anyway, not for the first time, that our
knowledge of the universe is still very incomplete, and that its study
is worth following up in all its chapters.

We may be certain that electricity exercises a much more important
influence in nature than is generally supposed, and that it plays a
_rôle_ in our own lives which is still practically unrecognized. In
the oppression we feel before the coming of a storm, and the sense of
relief we experience when it has passed, we have an instance of the
way in which physical and moral influences are apt to blend or
overlap.



CHAPTER II

ATMOSPHERIC ELECTRICITY AND STORM-CLOUDS


With such strange facts before us--facts the strangeness and diversity
of which baffle all hypotheses and forbid all definite conclusions--we
can but keep adding to our observations and accumulating other facts
which may tend to elucidate the mystery. The terrible ravages caused
every year by lightning make it necessary for us to find some means of
preventing the recurrence of certain memorable catastrophes. It is
only in the actual investigation of the phenomenon, in the study of
all its smallest manifestations, that we can hope to discover the
methods of the mysterious power.

From the earliest times mankind has devoted much thought to the
subject. If we glance back towards past centuries we find that thunder
and lightning have ever been regarded as a terrible agent of the will
of the powers above.

The strongest and subtlest brains of antiquity, Anaxagoras, Aristotle,
Seneca, were unable to form any kind of reasonable view regarding the
fantastic phenomena resulting from the force of nature and held so
mysterious to us moderns. Thunder and lightning were generally
believed by them to be due to emanations from the earth or to vapours
contained in the air.

The Etruscans, who flourished fifteen hundred years before Christ, and
who were much given to the study of nature, are said to have observed
the tendency of lightning to make for points, but no theory upon the
subject has come down to us from them.

Electricity for the ancients was an unplumbed ocean, whose slightest
fluctuations affected them in ways they could not understand. In vain
they appealed to their gods to help them to explain the enigma.
Olympus turned a deaf ear to their prayers.

Their imagination exhausted itself in researches into the nature of
such things as amber, in which they recognized the curious attribute
of attraction and repulsion for objects of slight weight. The poets
attributed it to the tears of Phaëton's sisters, lamenting over the
dreams of Eridan. Certain naturalists regarded it as a kind of gum
issuing from trees during the dry days. No one gave any thought to
electricity, by whose subtle fluid the earth and everything upon it is
penetrated and enveloped.

The superstitions connected with lightning would furnish forth
material in themselves for a very curious volume of stories--half
comic, half tragic.

With the Romans the fall of a thunderbolt was always taken as an omen.
In the reign of Domitian, thunder was to be heard once so constantly
during a period of eight months that the tyrant, frightened by the
bombardment from on high, at last cried out in his terror: "Let the
blow come, then, where it will!" The stroke fell upon the capitol, and
upon the temple of the Flavian family, as well as upon the emperor's
palace and the very room in which he slept. The inscription beneath
the triumphal statue was even torn away by the tempest and thrown into
a neighbouring garden.

Otto de Guérike, burgomaster of Magdeburg and inventor of the
air-pump, was the first person to discover the means of producing the
electric spark, about 1650. About the same time, Dr. Wall, while
watching electricity being released from a roll of amber, noticed a
spark and a sudden sharp report, suggestive of a minute flash of
lightning, followed by a minute peal of thunder. The analogy was
striking. This discovery opened out a new horizon to physicists, and
almost immediately the feeble electric light produced by the hand of
man came to be associated with the monstrous sheaves of fire let loose
in space by unknown forces.

L'Abbé Nollet, considered in the France of his time as an oracle in
regard to natural philosophy, expressed himself as follows upon this
subject:--"If some one, after comparing the phenomena, were to
undertake to prove that thunder is in the hands of nature what
electricity is in ours, that those electrical wonders with which we
are now able to make so much play are petty imitations of those great
lightning effects which frighten us; that both result from the same
mechanism; and if he could make it evident that a cloud produced by
the action of the winds, by heat, and by the mingling of exhalations,
bears the same relation to a terrestrial object as an electrified body
bears to an unelectrified body in its close proximity, I admit that
the idea, if well worked out, would captivate me greatly; and, to work
it out, how many plausible arguments there are at the disposal of a
man who is properly versed in electricity!"

The invention of the Leyden jar in 1746, and Franklin's brilliant
investigations, make these conjectures the more probable. Since then
electricity has gone ahead and become one of the most important
branches of modern natural philosophy.

When Franklin demonstrated that the air is in a permanent condition of
electrification even when the sky is clear, people began to study not
thunder alone but the general electrical state of the atmosphere. And
ever since meteorological observatories have made it a practice to
register every day the degree and nature of atmospheric electricity by
the use of very ingenious instruments.

But the records obtained up till now leave us in doubt upon many
points. The subject is still full of new surprises.

Whence come those masses of electricity which move about in the
clouds, sometimes escaping from them in thunderclaps and causing such
tremendous ravages upon this earth of ours? The evaporation of the sea
is one of their principal causes.

The atmosphere is continually impregnated with electric effluvia which
flow silently through the soil through the medium of all bodies,
organized or not, attached to the earth's surface. Plants afford an
especially welcome pathway to this fluid. The green leaves you see
rustling in the wind are often being traversed by electrical currents,
luckily harmless, of precisely the same nature as those of the deadly
lightning. On the other hand, the earth itself emits a certain
quantity of electricity, and it is from the attraction exerted by
these two fluids upon each other that thunder comes into existence. To
put it in another way, thunder is a sudden striking of a balance
between two different masses of electricity.

Minute researches have established the fact that in ordinary
conditions the terrestrial globe is charged with resinous, or negative
electricity, while the atmosphere holds in suspension _vitrée_, or
positive electricity.

In two words, our planet and its aerial envelope are two great
reservoirs of electricity, between which take place continual
exchanges which play a _rôle_ in the life of plants and animals
complementary to that which is played by warmth and moisture.

The aurora borealis, which sometimes illumines, with a brilliancy as
of fairyland, the darkness of night in the Arctic and all the regions
of the North, finds its explanation in the same phenomenon. It also is
a striking of a balance, silent but visible, between two opposing
tensions of the atmosphere and the earth; thus the apparition of the
aurora borealis in Sweden or Norway is accompanied by electric
currents moving through the earth to a distance sufficiently great to
cause the magnetic needle to record the occurrence in the Paris
Observatory.

Indeed, the electricity which pervades the earth, silently and
invisibly, is identical with that which moves in the heights of the
enveloping atmosphere, and, whether it be positive or negative, its
essential unity remains the same, these qualities serving only to
indicate a point, more or less in common, between the different
charges. The heights of the atmosphere are more powerfully electrified
than the surface of the globe, and the degree of electricity increases
in the atmosphere with the distance from the earth.

Atmospheric electricity undergoes, like warmth, and like atmospheric
pressure, a double fluctuation, yearly and daily, as well as
accidental fluctuations more considerable than the regular ones. The
maximum comes between six and seven in the morning in summer, and
between ten and twelve in winter; the minimum comes between five and
six in the afternoon in summer, and about three in the afternoon in
winter. There is a second maximum at sunset, followed by a diminution
during the night until sunrise. This fluctuation is connected with
that of the hygrometric condition of the air. In the annual
fluctuation the maximum comes in January, and the minimum in July; it
is due to the great atmospherical circulation; the winter is the time
when the equatorial currents are most active in our hemisphere, and
when the aurora borealis is to be seen most often.

On the other hand, the water of oceans and rivers is continually
evaporating under the influence of solar heat, and rises into the
atmosphere, where it remains in the form of an invisible gaseous
vapour. Soon it becomes cold again, and, in the process of
condensation, transparent gaseous molecules become transformed into
minute drops, which accumulate into a cloud.

Generally speaking, clouds are, like the atmosphere, charged with
positive electricity. Sometimes, however, there are negative clouds.
You may frequently see, on the summits of mountains, clouds which seem
to cling to the peaks for a while, as though drawn to them by some
force of attraction, and then move away to follow the general
direction of the winds. It often happens that in this case the clouds
have lost their positive electricity in thus coming in contact with
the mountains, and have derived from them in its place the negative
electricity which, instead of holding them, has a tendency to drive
them off. A mass of clouds lying between the negative earth and a mass
of positive clouds above is almost neutral; the positive electricity
accumulates towards its lower surface, and the first drops of rain
will make it disappear. This mass will, from that moment, become like
the surface of the soil--that is to say, it will become negative under
the influence of the mass above it, endowed with a strong positive
tendency.

The cloud remains suspended in space until the moment when, under the
influence of the ambient medium, it dissolves in rain.

The causes of the instability of clouds are very numerous. My readers
are aware that the atmosphere is being constantly agitated by vast
currents which pass from the equator to the poles, and from which the
different winds result.

The clouds take part in this universal whirl of atmospheric waves.
Transported from one point to another--often far beyond the region
where they came into existence--subjected to every vicissitude of
atmosphere, and blown about by contrary currents, they follow the
gigantic movements which take the form sometimes of cyclones and
tempests.

Under the influence of warmth, and probably also by its
transformation, these movements engender great masses of electricity,
and presently, when the clouds have become saturated with it, the
electricity breaks out, and there is a thunderstorm.

The electric fluid, escaped from the cloud in which it has been
imprisoned, flies to unite itself, either with the negative
electricity stored in the surface of the earth, or else with the
electricity in other neighbouring clouds. Almost always the cloud torn
open by the electric discharge dissolves in rain or hail.

Thus a storm is the outcome of violent movements produced by the force
of electricity when this has reached its maximum of intensity.
Thunderstorms are generally heralded by certain premonitory signs. The
barometer goes down steadily. The air, calm and heavy, is pervaded by
a bitter sulphurous odour. The heat is stifling. An abnormal silence
reigns over the land. All this has a remarkable effect upon certain
organisms, and produces nervous complaints, a buzzing in the ears, a
sense of painful oppression, a sort of good-for-nothingness that we
combat in vain.

In most cases storms come to us in France ready made, so to speak,
from the sea, borne in by the currents from the south-west; they are
the off-shoots of the cyclones, and are born in the tropics, moving in
lines from the south-west to the north-east. Ordinarily they lose part
of their strength _en route_ and come to an end suddenly with us.

There are, of course, home-made storms also, so to speak, especially
in France during our hot summers, when the sun is shining all the day,
and thus promoting the rapid evaporation of our seas and rivers.

The air is charged with a heavy mist which veils the horizon; the
barometer is going down, the thermometer going up. The sun looks
leaden though there are no clouds. When it approaches the meridian and
its rays are most scorching, columns of vapour ascend and become
condensed into the light clouds termed _cirri_. At the end of some
hours these clouds become attracted to each other, descend a little,
and become grouped together into what look like great masses of
cotton-wool. These are termed _cumuli_. Presently a small grey cloud
joins the others. It looks innocent and harmless, but very often this
is the beginning of the battle. First there ensues, perhaps, a
discharge or two of lightning without casualties, but soon the
bombardment becomes general, and long blinding fusillades flash
through space. The heavens, darkened over, seem to have sunk quite
low, and to have become a great black mass, from which the lightning
escapes in sudden jets. Rain and hail pelt down upon the earth to an
accompaniment of the rumbling of thunder. Confusion has fallen upon
the entire universe.

Then, finally, the fight comes to a close. The clouds disperse and
allow us to see once again a wide expanse of sunlit blue. The birds,
their hearts freed again from terror, begin to sing again. Flowers and
foliage and soil, refreshed by the rain, give out sweet perfumes. An
immense joy takes the place of the sense of melancholy and oppression.
It is good to see the sun again! Alas, though, there are grim
realities to be faced presently. The hailstones have destroyed the
crops and begotten famine--the lightning has sown death and plunged
whole families into mourning. It is with these misfortunes before us
that we make up our minds to do what in us lies to diminish the
destructiveness of this terrible force.

How are storm-clouds to be detected?

Generally speaking, their shape is very clearly defined, and they have
a look of solidity about them.

Their lower surface is often unbroken, presenting a level plain from
which there rise huge ragged protuberances like great plumes.
Sometimes, on the other hand, they have great projections underneath,
trailing quite near the ground.

Storm-clouds move generally in large numbers, and are generally
composed of two separate masses, differently electrified--the lower
one giving out negative electricity, the higher positive electricity.
The flashes of lightning occur generally between these two masses,
though also, less frequently, between the lower mass and the earth.

It may be said that, generally speaking, storms are the result of the
meeting of two masses of clouds differently electrified.

For long, physicists refused to admit the validity of any other
theory, and combated in particular the idea that lightning could issue
from a single isolated cloud.

This has, however, been established now as a fact, and in such cases
the flashes have always, of course, taken place between the cloud and
the earth.

Marcorelle, of Toulouse, reports that on September 12, 1747, the sky
being then pure and cloudless but for one round speck, there was
suddenly a thunderclap and a flash which killed a woman on the spot,
burning her breast but doing no damage to her clothes.

Here is another interesting case. Two priests of the Cathedral of
Lombey, who were standing in the area of their chapter-house, busy
winnowing, saw a small cloud approaching them little by little. When
it was immediately above them a flash of lightning broke out and
struck a tree just beside them, splitting it from top to bottom. They
heard no thunderclap. The weather was quite fine. There was no wind,
and this was the only cloud in the sky.

Storms are far more prevalent in some countries than in others.
According to Pliny, thunder was unknown in Egypt, and, according to
Plutarch, in Abyssinia. This could not be said now, however, perhaps
because these lands have grown unworthy of their exemption. It might
be said, however, of Peru, whose pure and limpid skies are never
troubled by tempest. _Jupiter tonans_ must be a myth indeed to a
people who know nothing of thunderclaps or wet days.

Storms diminish in number in high latitudes, but there are local
conditions which affect their distribution. Then they are particularly
frequent in countries that are thickly wooded and in mountainous
districts.

Arago came to the conclusion, after a considerable number of
observations, that, out in the open sea or among islands, there is no
thunder in the north beyond the 75th degree of latitude. This is not
absolutely so, but it is a fact that storms are very much rarer in the
polar regions. They become more and more frequent towards the equator,
and are very numerous in the tropics.

On either side of the equator storms come year after year with
remarkable regularity in the wet season, and at the time of the
monsoons.

At Guadeloupe and Martinique there is never any thunder in December,
January, February, or March.

In temperate climates there are scarcely any storms in winter; they
begin in the spring, and attain their maximum of intensity in the heat
of summer.

In Italy there are thunderstorms at almost all times of the year.

In Greece they come chiefly in spring and autumn.

It is noticeable that in all latitudes they come most often in the
afternoon.



CHAPTER III

THE FLASH AND THE SOUND


The Romans attributed a mysterious influence to each manifestation of
electricity. They divided lightning into individual and family
lightning, lightning of advice, monitory, explanatory, expostulatory,
confirmatory, auxiliary, disagreeable, perfidious, pestiferous,
menacing, murderous, etc., etc.

They adapted it to every taste and circumstance, but modern science
has come to put order into this Capharnaum.

When a cloud is superabundantly charged with electricity, this
electricity, which is compressed in the cloudy envelope, tries to
escape in order to join the electricity accumulated either in another
cloud or on the ground. An electric deflagration ensues, and a long
ignited dart precipitates itself into space, showing us on a large
scale what our experience of physics has taught us in a small way in
our laboratories. This luminous and often dazzling trail constitutes
lightning.

Lightning is not always the same, and in order to classify the
different forms it takes more easily, it can be divided into three
groups--diffused lightning, linear lightning, and fireballs. This last
is the most curious of the three. The variety and eccentricity of
fireballs are celebrated in the history of lightning, and I propose to
devote the following chapter to their vagaries.

Diffused lightning is the commonest of all. You can count hundreds of
flashes on a stormy night. Occasionally they succeed one another with
such rapidity that the sky is momentarily entirely illumined with a
fantastic brightness. At these times great sombre clouds can be seen
surging from the darkness of the night, to shine suddenly with an
ephemeral brightness of a diffused red, blue, or violet tinge. Their
irregular shapes, with their jagged edges of light, are visible
against the dark background of the heavens, and the thunder growls
monotonously. Whether the exchange of electricity is produced on a
vast stretch between two rows of clouds, or whether it is manifested
by a long thin spark launched like an arrow and veiled by the curtain
of clouds, all that can be seen is a strange light, vague, diaphanous,
instantaneous, which sometimes spreads itself like a sheet of fire all
over the horizon.

It is diffused lightning which gives us the finest storm effects on
those heavy summer evenings when the air is breathless and saturated
with electricity. Suddenly the clouds are illumined, nebulous veils
of light on which can be seen, in sombre fantastic, fugitive vision,
the outlines of the trees, houses, and other landmarks. Then, all at
once, heaven and earth fall back into a darkness deeper than before,
owing to the contrast.

Linear lightning is more terrible. It is regarded by astronomers as
the most perfect form of destructive lightning. It is a strong
flash--a thin trail of light--very clear, and extraordinarily rapid,
which shoots from an electric cloud to the earth, or from one cloud to
another.

Like a supple and undulating serpent of fire, it twists itself
luminously into space, spreading itself menacingly in the heavens with
its long spirals of light.

Sometimes--in a hurry, no doubt, to reach its prey--it effects its
passage in a straight line, but as a rule it follows a sinuous track,
and forms itself into a zigzag at an obtuse angle. The different forms
which this lightning takes are no doubt attributable to various
causes. One of the chief of these seems to be the unequal distribution
of humidity in the air, which renders it a more or less good
conductor. In fact, fulminic matter is strongly attracted towards damp
regions, and goes quickly from one point to another, guided in its
chosen way by the hygrometrical conditions of the atmosphere; and it
is these constant changes of direction which determine the meanderings
of its course. Thus the lightning would trace a sort of plan of the
hygrometrical state of the air for a certain portion of the
atmosphere. For it, the short road is hardly ever the straight line.

On the other hand, the variability of the overloading of electricity
has something to say to the form it takes.

Sometimes lightning forms itself into two or three branches, and
becomes forked lightning. Or it even divides itself into a number of
points from a principal branch, out of which a great many sparks burst
forth.

These incandescent sheaves move through space with extraordinary
agility. It has not been possible to measure their speed with absolute
accuracy, but their rapidity is such that their transit appears to be
instantaneous. The latest researches seem to have proved that their
speed is superior to that of light, which is 300,000 kilometres a
second.

Lightning is not always of a dazzling whiteness, it is often yellow,
red, blue, violet, or green. Its colour depends on the quantity of the
electricity thrown on the atmosphere by the discharge; on the density
of the air at the time of the passage of the ignited matter; on its
hygrometrical state, and on the substances which it contains during
suspension. It has been remarked in the study of physics that the
electric spark is white in the open air, but that it gets a violet
tinge in the vacuum of a pneumatic machine.

This proves that violet lightning comes from the far-off regions of
the atmosphere. It traverses a bed of rarified air, and shows the
great height of the storm-clouds from which it emanates.

The fulminating spark is so fugitive that it is difficult to form an
idea of its length. One could easily take it to be a yard or so long,
so illusory and deceptive are our impressions. As a matter of fact, it
is proved that flashes of lightning cover a distance of several
kilometres.

There are various methods to which one can have recourse in these
scientific researches. The first, which gives the length of horizontal
lightning, is based on a minute comparison between the trajectory
described by the meteor and the known distance of the terrestrial
points between which it travels. In order to gauge the extent of
vertical lightning, you must estimate approximately the height of the
clouds from which it comes, based on the irregularities of the earth
of which the height is known.

But there is a still simpler method for approximate measurement within
the reach of every one. It consists in multiplying 337 (the number of
yards traversed by sound in a second) by the number of seconds during
which the thunder lasts.

These methods all give the same result, and prove that lightning is
often 1, 5, and 10 kilometres in length. The greatest length proved up
to the present has been 18 kilometres. When one thinks of the
instantaneousness of these flashes, one marvels at their incomparable
agility, and we can only be lost in admiration of the magic force of
the heavenly sling, which is capable of hurling these whole rivers of
fire to roll in their sinuous course right through space, and in a
space of time almost inappreciable to our senses.

Yet, in spite of the extreme rapidity of the lightning, it has been
possible to determine that these meteors do not last the thousandth
part of a second. To prove this, we take a circle of cardboard,
divided from the middle into black and white sections. This circle can
be turned like a wheel almost as quickly as one can wish. We know that
luminous impressions remain on the retina the tenth part of a second;
thus, if we imitate the childish game of turning a lighted coal--if
the turn is made in the tenth of a second, each successive position of
the coal remaining impressed on the retina for the same length of
time--we have a continuous circle. In turning our cardboard wheel with
the black and white spokes, if each spoke passes before our eyes in
less than the tenth of a second, we can no longer distinguish between
the sections, but can only see a grey circle. But we can make it
rotate a hundred turns or more in a second; this being done, if we
continue to observe the circle, we can no longer see the lines, they
succeed each other more quickly in our eyes than the impression they
produce. But if the circle turns before us in the darkness, and it is
suddenly lighted up and as suddenly darkened, the impression produced
on our eyes by each of the sections would last less than the tenth of
a second, and the circle would appear to us as if it were stationary.
In applying a calculated rotation to this contrivance, Charles
Wheatstone has proved that some lightning does not last the thousandth
part of a second. This measure is probably a minimum; in the majority
of cases the duration of lightning is longer than this.

Often during the hot, transparent summer nights, we see a considerable
number of flashes, which furrow the firmament with their gentle,
bluish light. These fugitive gleams remind us in the sky of the
will-o'-the-wisps, which come forth silently from marshy ground. The
atmosphere is pure; there are no apparent traces of a storm, and yet
the sky is glistening with thousands of small flames. The flashes
succeed one another almost without interruption. These electric
sparks are known as heat-lightning, but this is quite inaccurate, and
has no meaning in the language of modern science.

In a great number of cases an astronomer would be able to discover
certain characteristic signs indicating that a storm is taking place
under the horizon at a very great distance from the point of
observation. It is only at the moment when the sky is lighted up that
one can see the ridge of clouds lying low on the horizon. At other
times there is no sign of a storm, as far as the eye can see. The
atmosphere is quite clear, and yet the sky is swept with a number of
electric flashes. But afterwards you hear that a violent storm has
devastated the region over which the gleams have appeared, and that it
is to this that they are attributable. They are only reflected lights.

A sailor tells us that once when he was out at sea, more than 100
kilometres from Lima, he saw a number of bright flashes, without any
thunder, to the east and north-east of the horizon. The weather was
perfect, and the sky absolutely serene. Now we know that storms, and
the electric phenomena which they produce, are unknown upon that
coast; but this immunity does not extend for more than 100 kilometres
to the interior of this country, so that this lightning which was
observed at sea, 100 kilometres from the shore, must have taken place
more than 200 kilometres away.

One of our correspondents, M. Soleyre of Constantine, sent us word, in
1899, of an interesting case of lightning without thunder.

"In August," he says, "I noticed it in the valley of the Arve above
Salambes; when I came back to Algiers I saw it again on September 16,
and on October 19.

"It was not sheet lightning, but ordinary lightning concentrated in
very thin lines. This lasted long, and was very near. Another thing,
there was no hail. This is not very rare in Algiers."

On September 1, 1901, I happened to be in Geneva at about 6 p.m. The
weather was heavy but very fine. I noticed a good deal of lightning on
the south-west of the horizon. It went on almost without interruption
above the Savoy Alps. Each flash illuminated at the same time the
ridge of the mountains and the fringed edge of the great sombre clouds
lying low on the horizon. This lightning was silent; the noise of the
thunder did not reach Geneva. The next day I learnt that a terrible
storm had devastated the neighbourhood of Chambéry and Aix-les-Bains.

Moreover, apart from storms, there have been other records of this
lighting up of the sky being observed at great distances.

Thus, in 1803, a service of luminous communications was established on
Mount Brocken in the Hartz Mountains in order to determine the
differences of longitude. The combustion of 180 to 200 grammes of
powder, burnt in the open air, for each of the signals, produced a
light which was observed by astronomers stationed on Mount Kenlenberg,
although they were 240 kilometres from Brocken, which is itself
invisible from Kenlenberg.

On certain fête-days, July 14, for example, when the principal
monuments in Paris are illuminated, at a distance of 20 and 30
kilometres we can see a sort of luminous vapour which floats above the
town and reflects the lights of the boulevards, although the lights
themselves are invisible from the point of observation.

Here is another example which any Parisian can verify: the captive
balloon of the Aërodrome at Porte-Maillot, which soars some hundreds
of yards above Paris during the spring and summer, as seen from the
dark paths of the Bois de Boulogne, appears against the azure of the
sky like a magnificent globe bathed in light, resembling an enormous
moon. Well, this gentle, pale light is only the reflection of the
lights of Paris which are invisible from the Bois de Boulogne.

The earth and all the planets which are dark in themselves, shine in
space lighted up by the sun.

The silent lightning which flashes in the sky is only the reflection
of a distant storm. Whether on account of the spherical shape of the
earth or on account of the irregularities of the land, the clouds are
invisible, but the effluvium which escapes from them can be seen at a
great distance.

These poetic and ephemeral flames which glide through the sky, appeal
to the imagination of the dreamer, and yet they are quite as terrible
as the flashes which are accompanied by thunder. If the noise which
accompanies these is not perceptible, it is because the sound of the
thunder does not carry far, and has been lost in space before reaching
us.

It is the same with the silent lightning which gleams in a stormy sky.
This phenomenon is particularly frequent in the Antilles. Either the
storm breaks too far from the observer, or the discharge has taken
place between two beds of clouds, the lower of which intercepts the
waves of sound without preventing the escape of the electric spark,
and the thunder is not heard.

As a rule we imagine that lightning always descends, that it comes to
us from the higher celestial regions to be lost in the common
reservoir. But this is quite inaccurate. Lightning sometimes ascends.
Sometimes it descends and reascends. That is to say, after it reaches
the ground, either there is no attraction there, or a stronger force
draws it back to the aerial regions, and it flies back to the clouds
whence it came.

As a rule we only fear the direct lightning. This is a great mistake.
There are many cases of lightning striking from a distance.

For example, at the end of May, 1866, an English coastguard was making
his rounds on the coast of one of the Shetland Isles, when a flash of
lightning passed near him, striking a great rock. The unfortunate man
was completely blinded, and plunged into darkness thus suddenly, he
would inevitably have fallen down an abyss, if his companions,
attracted by his cries, had not come to the rescue and taken him home.

Here is another case:--

On September 24, 1826, a terrible storm burst over Versailles,
accompanied by a great deal of thunder and lightning. At the moment
when the lightning struck Galli's farm, an old man who was in a street
in Versailles, at a distance of two kilometres from the farm, suddenly
felt a violent shock, accompanied by a feeling of oppression and
giddiness and a semi-paralysis of the tongue and the whole of his left
side. Next morning this had passed away, but in the evening at the
same time as the shock had occurred, he felt similar sensations of
fainting, and it was the same to the end of the week. It would be well
to remark here that at the moment of the accident, M. B---- happened
to be near the wall of a house, not far from the metallic tube which
conducted the rain-water into the level of the pavement.

The following phenomenon, to which we have already alluded, is no less
curious:--

On July 22, 1868, at about 7 o'clock in the evening, at Gien-sur-Cure
(Nièvre), the thunder had been growling violently for some time, when
all of a sudden the lightning struck a thatched house, which it set on
fire. At the same time a woman who was in a house ten yards away, felt
a shock, and saw the tiled floor rise beneath her. Her two sabots were
broken on her feet, and a bottle of Holy Water with which she was
blessing the house was broken in her hand, only the neck remained in
her fingers. She herself suffered nothing but the shock. Nineteen of
the tiles were flung in all directions.

Here is another very remarkable case of _ascending lightning_,
published in the _Comptes Rendus_ of the Academie des Sciences:--

At Porto-Alegre, on June 9, 1870, at 2 a.m., during a violent storm,
on the property of M. Laranja e Oliveira, at Brazil, a servant was
entering the house; he was about ten yards away, when a flash of
lightning illuminated it; at the same moment he felt a great tingling
in the flesh of his feet, then in his legs, then all over his body,
and finally in his head, on which the hair stood on end to such an
extent that _he was obliged to hold his hat on_ in order to prevent
its falling off. At the same time, a white flame burst from the ground
about two yards in front of him, accompanied by a shower of sparks.
Terrified by such a phenomenon, which he attributed to souls from
another world, he thought he was petrified to the spot; finally, he
ran away. Anything metallic which he had about him at the time of this
occurrence became magnetized. A key which was in his pocket remained
magnetic for two days.

Thus, as well as the ordinary fulguration, in which the lightning
(which we imagine descends from the clouds) acts directly on the body,
and the lightning which strikes indirectly, there are other electric
shocks which can be experienced by men and animals. Notable among
these is the _striking from the earth_, commonly known as _choc de
retour_, and which is in reality only an instance of the ascending
current, or of lightning striking from a distance. We must also
describe the striking _by a man who has been struck_.

The Abbé Richard, in his _Histoire de l'Air_, tells the following
story:--

In the neighbourhood of the village of Rumigny, in Picardy, on August
20, 1769, at six o'clock in the morning, there was a sudden irruption
of fulminating matter from the bosom of the earth in such quantities
as to produce the most violent results. The sky was cloudy, and looked
like a storm. A young farmer and his wife were following, at some
distance, a vehicle drawn by four horses. Suddenly the driver of this,
_without seeing the lightning or hearing the thunder_, was thrown to
the earth. His four horses were stretched dead on the ground near the
carriage. There was a _smoking hole_ in the ground, from which the
effluvium came forth and killed the young man and his wife at ten
paces off and separated from each other by twenty paces. The current
also knocked down, at a hundred paces, the father of the young man in
the same fashion as it had done the driver, but without injuring one
or the other.

The bodies showed no signs of a wound, only a considerable swelling
and a great deformity of the features. The woman, who was young and
pretty, became hideous; the whole of her body as well as that of her
husband was absolutely yellow. The four horses had their intestines
drawn from their bodies. They were all thrown on the same side. The
man's hat was pierced and his hair burnt, but he had no bruise on his
head.

This account, in which we must not be surprised to find the ideas and
language of the time (let us observe in passing that the man who was
struck did not hear the thunder, and had not even time to see the
lightning of which he was the victim)--this account, I say, gives us
an instance of ascending lightning. Here is another.

The traveller Brydone gives the following example, which he himself
observed:--

On July 19, 1785, a storm burst near Coldstream between 12 and 1 a.m.
A woman who was cutting hay on the banks of the Tweed _fell
backwards_. She at once called to her companions, and said she had
just received a violent blow on her foot for which she could in no way
account. At the time there was no thunder or lightning in the sky. The
shepherd of a farm at Lennel Hill saw a sheep fall near him, which a
few minutes before appeared to be in perfect health; he found it stone
dead. The storm then appeared very far off. Two carts laden with coal,
and each driven by a young driver seated on a small seat in front,
crossed over the Tweed. They had just climbed a small hill near the
banks of this river when they heard a great detonation round about,
similar to that which would be produced by the discharge of several
guns. At the same instant the driver of the second cart saw the first,
with his companion and the two horses, fall to the ground. _The driver
and horses were stone dead. The ground was pierced with three circular
holes at the very spot where the wheels had touched it when the
accident happened._ Half an hour after this event the holes emitted an
odour which Brydone compared to that of ether. The two circular iron
bands which covered the felloes of the wheels showed evident signs of
fusion in the two spots which rested on the ground at the moment of
the detonation, and in no other place. The skin of the horses had been
burnt, particularly about the legs and under the stomach. The body of
the driver had marks of burning here and there. His clothes, his
shirt, and, above all, his hat, were reduced to shreds, and gave out a
strong smell.

Orioli gives an example of two men who were surprised by a violent
storm near the village of Benvenide. They lay down on the ground to
let the meteor pass. Some moments later one of them got up feeling
very tired, but the other was dead. The bones of the latter were so
soft that it was easy to bend them; his whole body was of the
consistency of paste. The tongue had been torn from the roots, and no
one knew what had become of it.

Now, just as the earth can strike, so can the human body become
fulminating and act like lightning. After having been struck, it can
effectively acquire the power to strike in its turn.

For instance, on June 30, 1854, a man named Barri was killed by
lightning near the Jardin des Plantes, in Paris, and his body lay for
some time exposed to a beating rain. After the storm had passed, two
soldiers from the neighbouring guard-house tried to remove the body,
and each received a violent blow when they touched it. They got off
with a shock, perhaps because the body had been drenched with rain,
which acted as a conductor to the electricity, and thus it had had
time to lose a part of the fluid.

What a mysterious world is that of atmospheric electricity! It is
truly the New World for the scientific mind--a mine, fruitful in
unknown and even unsuspected marvels, which is perpetually disclosing
its riches for our admiration.

One of our most valued collaborators in our researches on the nature
of lightning is photography. Faithfully and unhesitatingly it
registers an indestructible document of the fugitive lightning, which
imprints itself on the sensitized plate, and the astronomer can
afterwards examine the smallest details of the sudden apparition
comfortably and at his leisure. We have already a considerable number
of plates of the outline of the lightning in flight. An examination of
these electric pictures is very interesting.

Who knows whether, later on, when phonography is brought to
perfection, it will not also register the noisy accompaniment to the
electric flash? Then, with the help of the cinematograph, we could
have dramatic representations of sensational storms. While the
photograph unrolls all the phases of the lightning, from its emerging
from the cloud to its fall to earth, before the gaze of the
spectators, the phonograph will repeat the sonorous accents of the
terrorizing voice of thunder.

Thunder, as all the world knows, is the noise which accompanies
lightning. It is produced when a change of electricity--a
neutralization--takes place between two points more or less distant.
The causes which provoke it are still somewhat of a mystery.

The luminous rocket which flings itself precipitately from a cloud
saturated with electricity, spreads itself like a trail of flames in
the atmosphere where an infinity of invisible molecules are floating;
these it repels. The passage of this whirlwind of fire in a centre
which is greatly compressed produces a momentary void into which the
surrounding air at once rushes, and it is the same all the way along
the route followed by lightning.

In all probability the equilibrium of the atmosphere, which is
momentarily disturbed by the intrusion of the ignited matter, hastily
re-establishes itself by a rush of the air which the lightning has
ejected, and which is swallowed up with a crash in the opening which
has been made. It is, on a large scale, a similar phenomenon to that
which is produced by opening a case which has been hermetically
sealed. The air rushing in makes a dull noise.

Pouillet objects to this very natural explanation on the ground that
the flight of a cannon-ball ought to produce a similar noise. But
this objection errs in its basis, because, as regards velocity, a
cannon-ball is as a tortoise as compared with the arrow of lightning,
and as regards size, who can compare a few grammes of powder to the
torrents of fire launched into space by the prodigious force of
electricity?

The lightning discharge produces a violent concussion in the cloud,
and very often a shower of rain immediately follows it. The electric
conditions of the different clouds which make a storm being separately
liable the one to the other, the discharge of one must lead to that of
several others more or less distant. In all cases the noise is caused
by the expansion of the air where a more or less partial void has been
made. It is the same with firearms, _crève-vessie_, etc.

One of the chief characteristics of thunder is the rolling, which is
often prolonged, and reverberates on the sides of steep mountains.
This voice, with its lugubrious tone, becomes grave and sometimes
sinister in the revolution of space--this voice, celestial and
infernal, seems to momentarily dominate the world, while the clouds
are enveloped with a thousand diabolical flames. Sometimes it rings in
the air with fierce calls, at others it spreads itself in dull,
languorous complaints.

Nevertheless, the intenseness of thunder undergoes a thousand
fluctuations, and presents astonishing variations. Generally it
strikes and frightens, but the curious thing is that, for the ear, in
reality it is less strong than the crinkling noise of a piece of paper
torn close to it.

Often, too, it may be compared to the discharge of firearms, a pistol
or a cannon.

Thus, when the lightning penetrated Volney's apartments at Naples, the
people present, among whom was Saussure, had the impression of a
pistol-shot in the next room.

There is a case given of M. and Mme. Boddington, who were seated on
the back seat of their coach in order to enjoy the view of the
country, and had given the inside seats to two servants. Suddenly
there was a flash of lightning, which struck M. and Mme. Boddington
and flung the postillion to a great distance. The servants were
untouched, and escaped with a fright. When they got over their terror,
one of them said that a very brilliant flash of lightning had been
immediately followed by a noise similar to that of a heavily charged
musket. He thought some one had shot the horses. His fright had
stunned him so that he hardly knew what had happened.

At other times thunder is accompanied by a whistling noise, but as a
rule it is the rolling which predominates.

We ask ourselves to what it is due that this rolling lasts so long.
There are several causes. The first is due to the length of lightning
and the difference in speed between sound and light. Let us suppose,
for example, a flash of lightning, AE, 11,000 metres long. The
observer stationed at O, underneath extremity E of the lightning
(which is one kilometre high), will see the lightning in its full
length in one indivisible instant. The sound will form itself also at
the same instant all along the line of lightning, but the sound-waves
will only reach the ear of the observer at different times. That which
starts at point E, the nearest, will arrive in 3 seconds, sound
travelling about 337 metres a second. That which is formed at the same
moment at point D, 2000 yards from point O, will take double the time
to arrive. That which comes from point C will not arrive for 12
seconds. The sound formed at B will not arrive until the time
necessary to cover 8 kilometres--that is to say, not for 23
seconds--and the sound formed at A will only reach after 32 seconds.
Thus the rolling will have lasted more than half a minute from start
to finish.

[Illustration: DIAGRAM EXPLAINING THE DURATION OF THE SOUND OF
THUNDER.]

And if, which is very often the case, the astronomer is not exactly
under one of the extremities of the lightning, but at some other point
in its course, he first hears a clap, then an increased noise, then a
diminution. In fact, in this case, the sound which leaves point D just
overhead, which is 1000 metres off, arrives alone in 3 seconds, but
the sounds formed from D to E on one side, and from C to D on the
other, arrive at the same time, having joined each other, taking 9
seconds, which is the necessary time to come from 1000 to 3000 metres.
The sounds beyond C arrive and depart according to distance, as in the
preceding example, and the thunder has lasted 23 seconds instead of 32
seconds.

[Illustration: COMMENCEMENT, AUGMENTATION, AND DIMINUTION OF THE
INTENSITY OF THUNDER.]

I must add that lightning is never straight, but always crooked.

The length of time the thunder rolls has nothing to do with the
distance of the cloud where the phenomenon begins. It is proportionate
to the length of the lightning with which it is associated. The
rolling is often still more prolonged by a succession of small
discharges, which follow each other very rapidly between the stormy
clouds; by the zigzags and ramifications of the lightning caused by
the hygrometrical diversity of the different beds of air; by the
echoes repeated by the mountains, the earth, the water, and the clouds
themselves--to all which must be added also the interferences caused
by the encounter of the different systems of sound-waves.

Its duration is extremely variable, however; it rarely exceeds 30
seconds, though the noise may sometimes seem to last much longer, so
that an observation of this kind may have any value--one must take
into consideration the echo, and isolate a single clap from the series
of discharges which take place in the bosom of the storm. The longest
verified duration of a single discharge is 45 seconds. That is
tremendous if we think of the instantaneousness of the lightning, and
reflect that the flash and the sound are produced in reality at the
same moment, that they are dependent the one on the other, and that in
their various manifestations there is only the difference of motion.

Sound moves like a tortoise behind the swift lightning, whose
vibrations spread in the air with inconceivable rapidity.

Hence these 45 seconds correspond to a flash of lightning more than 15
kilometres in length, but we know that there are even longer ones.

I have already said that we can calculate the distance of the
celestial cannon from which the fulminating discharge comes by
counting the number of seconds which separate the apparition of the
lightning from the first growls of the thunder. Thus the longest
interval that has been proved between the appearance of the lightning
and the noise it produces is 24 kilometres. This, however, is a
maximum.

Numerous observations have proved that thunder is never heard beyond
20 or perhaps 25 kilometres. Lightning pierces the cloudy veil, but
the voice of thunder does not carry so far. In this the great Jupiter
shows himself inferior to the ingenuity of human pigmies, whose
destructive and barbarous art has been able to invent infernal
machines the noise of which can be heard much further.

Cannon can easily be heard at a distance of 40 kilometres. Sometimes,
in sieges and big battles the cannonades can be heard muttering
lugubriously more than 100 kilometres away.

During the siege of Paris, Krupp's cannon--that most expeditious of
all vehicles of civilization in the eyes of the statesmen of this
planet!--could be heard as far as Dieppe, 140 kilometres away, during
the nights when they were bombarding. The cannonade of March 30, 1814,
which crowned the First Empire, as it crowned the Second, was heard
between Lisieux and Caen, a distance of 175 kilometres. Arago even
alleges that the cannon at Waterloo could be heard as far as Creil,
which is 200 kilometres away. Thus man's thunder can be heard at a
greater distance than that of nature. It is true that it is
incomparably more vicious, and that it has a great many more victims.

In its natural state, if we might explain it thus--left to itself--it
comes directly to us from the high regions of the atmosphere, and is
the most terrible of aerial messengers--a subtle messenger, malicious
and violent, it is the terror of the human race. But ruled by the
genius of man, it becomes a powerful agent towards modern
civilization, and we cannot sufficiently admire its many advantages.

If we could tame lightning and guide it safely, its services would
probably become innumerable. Lightning as man's right hand! Why not?
Was it not the auxiliary of the gods in the dark ages? To-day, is it
not regarded by astronomers as one of the most important forces of
nature? Why should it not be the collaborator of man's intelligence
to-morrow?



CHAPTER IV

FIREBALLS


Here we penetrate into what is, perhaps, the most mysterious, and
certainly the least understood domain of thunder and lightning.

Among all the electrical phenomena to be observed in the atmosphere,
there is nothing stranger than those fireballs of which we have
already spoken, and which in form and size recall the electric lights
in our Paris boulevards. Curious the contrast between electricity
tamed and civilized and electricity running wild! Between the arc
lights fulfilling their peaceful and useful function as substitutes
for the sun, and these dread engines of destruction sowing death and
havoc!

It is not long since the existence of these fireballs has been
acknowledged by scientists as an actual fact. Until quite recent times
they were regarded as the figment of excited imaginations, and wise
men smiled at the wild stories of their ravages. Their reality has now
been established, however, beyond the possibility of doubt.

In shape they are not always quite spherical, though this is their
normal appearance; and although their contours are usually clearly
defined, they are sometimes encircled by a kind of luminous vapour,
such as we often see encircling the moon. Sometimes they are furnished
with a red flame like a fuse that has been lit. Sometimes their course
is simply that of a falling star. Sometimes they leave behind them a
luminous trail which remains visible long after they themselves have
disappeared. They have been described as looking like a crouching
kitten, an iron bar, a large orange--so harmless apparently, that you
were tempted to put out your hand to catch it. There is record of one
being seen as large as a millstone.

One remarkable thing about them is the slowness with which they move,
and which sometimes enables their course to be watched for several
minutes. In our first chapter we gave several instances of the
occurrence of fireballs. Let us look at some more. Here is one taken
from Arago's learned treatise upon thunder. The record is from the pen
of Batti, a marine painter in the service of the Empress of Austria
and resident at Milan.

"In the month of June, 1841, I was staying at the Hôtel de l'Agnello
in a room on the second floor, overlooking the Corso dei Servi. It was
about six in the afternoon. The rain was coming down in torrents, and
the darkest rooms were lit up by the lightning flashes better than our
rooms generally are by gas. Thunder broke out every now and again with
appalling violence. The windows of the houses were closed, and the
streets were deserted, for, as I have said, there was a steady
downpour, and the main road was turned into a torrent. I was sitting
quietly smoking, and looking out at the rain, which an occasional ray
of sunlight set flashing like threads of gold, when I suddenly heard
voices in the street calling out 'Guarda, guarda!'--'Look, look!' and
at the same moment a clatter of hob-nailed boots. After half an hour
of absolute silence, this noise attracted my attention. I ran to the
window, and looking to the right, in the direction of the clamour, I
saw a fireball making its way down the middle of the road on a level
with my window, in a noticeably oblique direction, not horizontally.
Eight or ten persons, continuing to call out 'Guarda, guarda!' kept
pace with it, walking down the street, stepping out quickly. The
meteor passed my window, and I had to turn to the left to see what
would be the end of its caprice. After a moment, fearing to lose sight
of it behind some houses which jutted out beyond my hotel, I went
quickly downstairs and into the street, and was in time to see it
again and to join those who were following its course. It was still
going slowly, but it was now higher up, and was still ascending--so
much so that after a few minutes it hit the cross upon the clock tower
of the Chiesa dei Servi and disappeared. Its disappearance was
accompanied by a dull report like that of a big cannon twenty miles
away when the wind carries the sound.

"To give an idea of the size and colour of this globe of fire, I can
only compare it to the appearance of the moon as one may see it
sometimes rising above the Alps on a clear night in winter, and as I
myself have seen it at Innsbrück--that is to say, of a reddish yellow,
with patches on it almost of red. The difference was that you could
not see the contours of the meteor distinctly as you could the moon,
and that it seemed to be enveloped in a luminous atmosphere of
indefinite extent."

This fireball was an innocuous one. We may take next, by way of
contrast, the case of one which wreaked terrible damage and loss of
life.

On July 27, 1789, at about three o'clock in the afternoon, a fireball
of about the size of a cannon-ball, fell in a great hall at Feltri
(Marche Trevisane) in which six hundred people were seated, wounded
seventy and killed ten, putting out all the lights.

On July 11, 1809, about eleven o'clock in the morning, a fireball
penetrated into the church of Chateauneuf-les-Moustiers (Basses-Alpes)
just as the bell was ringing and a large congregation had taken their
seats. Nine persons were killed on the spot and eighty-two others were
wounded. All the dogs that had got into the church were killed. A
woman who was in a hut on a neighbouring hill saw three fireballs
descend that day, and made sure they would reduce the village to
ashes.

Müsschenbroek recounts the following incident which took place at
Solingen in 1711. M. Pyl, the Pastor at Duytsbourg, was preaching one
Sunday, when in the middle of a storm a fireball fell into the church
through the clock tower and exploded. The sanctuary was set on fire
and became thick with smoke. Three persons were killed and more than a
hundred were wounded.

From the _Bulletin_ of the Société Astronomique de France the
following narrative contributed to it by Mlle. de Soubbotine, a member
of this society, has been taken:--

"A terrible storm broke out at Ouralsk on May 22, 1901. It was a
_fête_ day and the streets were thronged with people. Towards five in
the afternoon some young men and girls, twenty-one in all, had taken
refuge in the vestibule of a house, and a girl of seventeen, Mlle. K.,
had sat down on the threshold, her back turned towards the street.
Suddenly there was a violent clap of thunder, and in front of the door
there appeared a dazzlingly brilliant ball of fire, gradually
descending towards where they were all grouped. After touching Mlle.
K.'s head, who bowed down at once, the fireball fell on the ground in
the middle of the party, made a circuit of it, then forcing its way
into the room of the master of the house, whose boots it touched and
singed, it wreaked havoc with the apartment, broke through the wall
into a stove in the adjoining room, smashed the stove-pipe, and
carried it off with such violence that it was dashed against the
opposite wall, and went out through the broken window.

"After the first feeling of fright, this is what transpired. The door
near which Mlle. K. was seated had been thrown back into the court,
and in the ceiling there were two holes of about 18 centimetres each.

"The young girl, still seated with her head bowed down, looked as
though she were asleep. Some of the people were walking in the
courtyard, having seen and heard nothing, and the others were all
lying in the vestibule in a dead faint. Mlle. K. was dead. The
fireball had struck her on the nape of her neck and had proceeded down
her back and left hip, leaving a black mark all along. There was a
sore on one hand, with some blood on it, and one of her shoes was torn
completely off, and there was a small hole in one of the stockings.

"All the victims became deaf."

On September 10, 1845, at about two in the afternoon, in the course of
a violent storm, a fireball came down the chimney into a room in a
house in the village of Salagnac (Creuse). A child and three women who
were in the room suffered no harm from it. Then it rolled into the
middle of the kitchen, and passed near the feet of a young peasant who
was standing in it. After which it went into an adjoining room, and
disappeared without leaving any trace. The women tried to persuade the
man to go in and see whether he could not stamp it out, but he had
once allowed himself to be electrified in Paris, and thought it
prudent to refrain. In a little stable hard by, it was found
afterwards that the fireball had killed a pig. It had gone through the
straw without setting fire to it.

On July 12, 1872, a new form of fireball made its appearance in the
Commune of Hécourt (Oise). It was of the size of an egg, and it was
seen burning upon a bed. Efforts were made in vain to extinguish it,
and presently the entire house, together with the neighbouring
dwellings and barns, became a prey to the flames.

On October 9, 1885, at 8.25 p.m., during a violent storm, a globe of
fire of the size of a small apple was seen coming into a ground-floor
room in a house at Constantinople through an open window, the family
being at table in this room at the time. It first played round a
gas-jet, then, moving towards the table, it passed between two guests,
went round a lamp hanging over the centre of the table, and then
precipitated itself into the street, where it exploded with an
appalling crash, but without having caused any damage or hurt anybody.
Not far from the scene of this phenomenon there are a number of
buildings provided with lightning conductors. The fireball left no
trace of smell behind it.

Here is another curious narrative of a fireball.

A party of five women took refuge during a storm in the entrance to a
house in order to escape from the rain and the lightning.

They had scarcely gained the doorway when there was a tremendous
thunderclap which sent them flying backward--and two girls who had
joined them--knocked senseless by lightning in the form of a fireball.
One of the girls remained unconscious for a long time; all the others
were more or less seriously injured, but all recovered. The strangest
circumstance in connection with this affair, however, still remains to
be told.

[Illustration: SINGULAR CASE OF THREE FIREBALLS OBSERVED IN PARIS ON
JUNE 10, 1905, BY M. H. RUDAUX.

They were seen to descend in this way upon the lightning conductor
above the Palais Royal electric-power station. This engraving, after a
sketch made at the time by M. Rudaux, appeared in _La Science
Illustrée_, for August, 1905.]

On the same side of the street as the passage, in a neighbouring
house, nine or ten yards away, in a ground-floor room of which the
door was shut, a young woman was working at a sewing-machine. At
the moment of the thunderclap, she experienced a violent shock
throughout her whole body, and a fierce burning sensation in the
hollow of her back. It was found afterwards that between the
shoulder-blades and also on her leg, she had been badly scorched, but
the wounds quickly healed. Now, in the room of this victim, no trace
was to be found of the passing of the fireball, neither on the
ceiling, nor on the floor, nor on the walls. There was absolutely
nothing to show how the electric fluid could have made its way in from
the spot in which the fireball had exploded in the neighbouring house,
separated from it by two thick walls.

Mysterious, is it not? The fireball seems to dwindle out of sight. In
some cases, it seems to reduce itself into vapour in order to pass
from one place to another.

With animals these fireballs seem deadlier and more merciless than
with human beings.

Thus, on February 16, 1866, a thunderstorm descended upon a farm in
the Commune of Chapelle-Largeau (Deux-Sèvres), and the circumstances
attending its explosion are too remarkable to be overlooked. After a
tremendous thunderclap, a young man who was standing near the farm saw
an immense fireball touch the ground at his feet, but it did him no
damage, but passed, still harmlessly, through a room in the farmhouse
in which there were nine persons. The only effect it produced was the
flaring up of some matches upon the chimney-piece.

It proceeded towards the stables, which were divided into two
compartments. In one there were two cows and two oxen: the first cow,
to the right of the entrance, was killed, the second was uninjured;
the first ox was killed, the second was uninjured.

The same effect was found to have been produced in the other
compartment, in which there were four cows; the first and the third
were killed, the second and fourth were spared: the odd numbers taken
and the even numbers left.

Similar freaks have been recorded in connection with piles of plates
struck by lightning--holes being found in alternate plates. How are
these things to be explained?

The following story is very extraordinary, though it does not help to
clear up the mystery of lightning's strange ways:--

On August 24, 1895, about ten in the morning, in the midst of a storm
of wind and rain, several persons saw descending to the ground a
whitish-coloured globe of about an inch and a half in diameter, which,
on touching the ground, split into two smaller globes. These rose at
once to the height of the chimneys on the houses close by and
disappeared. One went down a chimney, crossed a room in which were a
man and a child, without harming them, and went through the floor,
perforating a brick with a clean round hole of about the size of a
franc. Under this room there was a sheepfold. The shepherd's son,
seated at the doorway, suddenly saw a bright light shining over the
flock of sheep, while the lambs were jumping about in alarm. When he
went up to them, he was startled to discover that five sheep had been
killed. They bore no trace of burning, or of wound of any kind, but
about their lips was a sort of foam, slightly pink in colour.

In the adjoining house, the second fireball had also gone down a
chimney, and had exploded in the kitchen, causing great damage.

In 1890, a young farmer was working on a plot of ground, two or three
miles from Montfort-l'Amaury. A storm breaking out, he stood up
against his horses to take refuge from the rain; moving away a few
yards in order to get his whip, there was seen, when he returned, a
ball of fire almost touching the ear of one of his horses. A moment
later it exploded with a deafening noise. The two horses fell--one of
them unable to get up again. The farmer himself was dashed to pieces.

On other occasions the meteor is hardly more devastating than the
ordinary bomb.

On April 21, at Lanxade, near Bergerac, a storm had been raging
already for some hours, when suddenly--simultaneously with a small
thunderclap--a ball of fire, of the size of the opening of a sack of
corn, fell slowly on one of the banks of the Dordogne, spoiling some
fruit trees, and then crossing the river, it raised a waterspout
several yards high as it went.

It disappeared finally on the other side of a field of corn.

On November 12, 1887, a very curious instance of a fireball was
noticed on the Atlantic.

It was at midnight, near Cape Race. An enormous fireball was seen to
rise slowly out of the sea to the height of sixteen or seventeen
metres. It travelled against the wind, and came quite near the vessel
from which it was being watched. Then it turned towards the south-east
and disappeared. The apparition lasted about five minutes.

In July, 1902, in the course of a violent storm, and immediately after
a loud peal of thunder, a fireball of about the size of a toy balloon
was seen to make its appearance suddenly in the Rue Veron at
Montmartre. After moving along, just above the ground, in front of a
wine-merchant's shop, it exploded like a bomb, most fortunately
without hurting any one, or doing any damage.

The little village of Candes, situated by the confluence of the Vienne
and the Loire, was the scene of the appearance of a fireball in June,
1897. Three persons were sitting in the verandah of a house during a
storm, when they suddenly saw a fireball travelling past them through
the air for a distance of thirty yards or so. Then it exploded with a
loud noise, striking sparks from the ironworks of the verandah. At the
same moment, the servants saw another fireball cross a garden at the
other side of the house, and drop into a small pond. A gardener was
knocked over, but not hurt.

On March 6, 1894, M. Dandois, professor of surgery at the University
of Louvain, went to the neighbouring town of Linden, by railway, to
see a patient. On his return, on foot, the sky suddenly so darkened
over, that he made for the nearest dwelling-place, avoiding, as he did
so, the telegraph poles along the road. Suddenly a ball of fire came
against him and threw him over a ditch into a field, where he lay
unconscious.

A quarter of an hour later, having regained his senses and finding
himself undamaged save for a numbness in one arm and one leg, the
doctor set out again, congratulating himself on the fact that his
umbrella had acted as a sort of portable lightning conductor, for the
steels were all twisted, and showed signs of having borne the brunt of
the fray. Had the handle been of steel also, the electric current
would have run down it into his hand, doubtless, and killed him.

On another occasion a fireball fell upon the door of a house, pushed
it violently open, and made its way into the kitchen.

At the sight of this strange visitor, the cook bolted from the room. A
sempstress, who was at work near the window, received a small burn on
her forehead, of about the size of half a franc, with a slight weal a
couple of inches long--like the tail of a comet.

After bursting, the fireball made its way up the chimney, from which
it removed a mass of soot, smelling somewhat of sulphur.

Here is an instance more curious still--

A violent storm was raging near Marseilles, when seven persons, seated
together in the ground-floor drawing-room of a country house, saw a
fireball as big as a plate appear in their midst.

It directed its course towards a young girl of eighteen, who,
frightened out of her life, had fallen on her knees. Touching her
shoes, it rebounded to the ceiling, then came down to her feet again,
and so on two or three times, with mysterious regularity, the girl
experiencing, it seems, no other sensation than that of a slight cramp
in her legs. Eventually the fireball made its exit from the room
through a keyhole!

The girl could not get up at once after it had gone. For a fortnight
or so she could not walk without assistance, and it was two years
before she got over a liability to sudden weakness in her legs,
causing her suddenly to fall.

It is strange to reflect that these diminutive fireballs, produced by
the actual atmosphere we breathe, are less understood by us than that
enormous globe which we call the sun, and to which is due the
flowering of the entire life of our planet. If we are still in doubt
as to the nature of the sun's spots, at least we have been able to
analyse its own elements. And we know its dimensions, its weight, its
distance from us, its rate of rotation, etc., etc.

Yet these electric spheres that make their escape from the clouds in
times of storm, baffle our investigations altogether.

According to records which seem authentic, fireballs have been seen
actually to come into existence upon the surface of a ceiling, at the
mouth of a well, and upon the flagstones of a church.

In 1713, at the château of Fosdinaro, in the neighbourhood of Massa
Carrara, in the course of a storm and heavy downpour of rain, there
was seen to appear suddenly upon the ground a very vivid flame, white
and blue in colour. It seemed to flare fiercely, but did not move
apparently from the one spot, and after growing quickly in volume it
suddenly disappeared. Simultaneously with its going, one of the
observers felt a curious sort of tickling behind his shoulder, moving
upwards; several bits of plaster from the ceiling under which he stood
fell upon his head, and there was a sudden crash quite unlike an
ordinary thunderclap.

In 1750, on the 2nd of July, at about three in the afternoon, the Abbé
Richard happened to be in the church of St. Michel at Dijon during a
storm. "Suddenly," he tells us, "I saw between two pillars of the nave
a bright red flame floating in the air about three feet above the
floor. Presently it rose to a height of twelve or fifteen feet,
increasing in volume. Then, after having moved some yards to one side,
while still rising diagonally to the height almost of the woodwork of
the organ, it disappeared at last with an explosion like the report of
a cannon."

On July 21, 1745, a violent storm broke out in Boulogne, and the tower
of a convent was struck by a fireball. It was of great size, and was
seen to emerge from one of the sewers of the town and to move along
the surface of the road until it hit against this tower, of which a
part subsided. No one was hurt. A nun affirmed that some years before
she had seen just such another fireball emerge from the same spot and
precipitate itself with a crash against the summit of the tower
without doing any damage.

In the middle of a violent storm, Dr. Gardons saw several fireballs
flying in different directions, not far from the ground, making a
crackling sort of noise. One of them was seen by witnesses to come out
of an excavation full of stagnant water. They killed one man, several
animals, and did much damage to the trees and houses in the vicinity.

In February, 1767, at Presbourg, a blue, conical flame escaped
suddenly with a detonating noise from a brasier, breaking it to
pieces, and scattering the glowing cinders all around. It then went
twisting about the room, burnt the face and hands of a child, escaped
partly through the window, partly through the door, broke into a
thousand pieces a second brasier in another room, and disappeared
finally up a chimney, carrying up with it and discharging from the
chimney-top into the street several hams which had been hung under the
chimney-piece. For several days afterwards the atmosphere of the house
retained a smell of sulphur.

In some cases, fireballs have been seen to come down from the sky
apparently, and then, after almost reaching but not actually touching
the ground, to ascend again. Thus on a hot day in summer 1837, M.
Hapoule, a landed proprietor in the department of the Moselle,
standing in front of the entrance to his stables under the shelter of
a porch during a storm, saw a fireball about the size of an orange
moving in the direction of a dung-heap not far from him. But instead
of going right into it, it stopped about a yard off, and changing its
route, it went off at an angle, keeping the same level for some
distance, when it suddenly seemed to change its mind again, and rose
perpendicularly till it disappeared in the clouds.

These sudden changes, as we have seen, are strangely characteristic of
the habits of fireballs.

The Garde Champêtre of the village of Lalande de Libourne (Gironde)
was traversing the country one evening about half-past ten, engaged in
organizing a _garde de surveillance_, when he suddenly found himself
surrounded by a bright and penetrating light. Astonished, he looked
behind him, and saw a fireball, just broken loose from a cloud,
descending quickly to the ground.

The light vanished presently, but he made his way towards where the
fireball seemed to be falling. When he had gone about two hundred
yards, he saw another brilliant light breaking out from the top of a
tree and spreading itself into a sheaf of rays, every point of which
seemed to emit electric sparks.

At the end of a quarter of an hour the light became weaker, and then
disappeared. The tree was afterwards cut down, and it was found that
the lightning had gone down the centre to a distance of three yards,
and had then passed down outside to the soil, leaving trace of a
semi-circular route; and finally, after rising again on the opposite
side of the tree to a height of four yards, tearing off two narrow
strips of bark, had disappeared. At the foot of the tree a small hole,
about an inch and a quarter in diameter, retained a certain degree of
warmth for an hour and a half afterwards.

Fireballs often keep within the frontiers of cloud-land. They may be
seen passing sometimes from one cloud to another in the high regions
of the atmosphere.

On September 22, 1813, at seven in the evening, M. Louis Ordinaire saw
a fireball leave a cloud at the zenith--the sky being very much
lowering at the time--and go towards another. It was of a
reddish-yellow and extremely brilliant, lighting up the ground with a
bright radiance.

He was able to follow its movements for at least a minute, and then
saw it disappear into the second cloud. There was an explosion
followed by a dull sound like the firing off of a cannon in the
distance.

After a violent storm which broke out near Wakefield on March 1, 1774,
there remained only two clouds in the sky, just above the horizon.
Balls of fire were observed gliding from the higher of the two into
the lower, like falling stars.

In high mountainous districts--in the Alps, for instance--you may
often look down from above upon a storm. It is fascinating thus to
watch the grandiose spectacle of the elements at war. Here from the
pen of Père Lozeran du Fesch is a striking picture of such a scene--

"It was on the 2nd of September, 1716, about three o'clock in the
afternoon. A traveller was making his way down towards Vic from the
summit of Cantal, accompanied by a guide.

"The weather was calm and very warm, but down below, about the middle
of the mountain, a vast sea of mist stretched out in wavelike clouds.

"These clouds were furrowed continually by lightning flashes, some
going quite straight, some zigzag, some taking the shape of fireballs.
When the two men came near this region of clouds, the mist grew so
thick they could hardly see the bridles of their horses.

"The air became gradually more cold and the darkness more dense as
they proceeded downwards. Now they were in the midst of the fireballs
flying in every direction all round them, revolving as they went,
reddish in colour, like saffron lit up.

"They were of all sizes--some quite small on their first appearance,
seeming to grow immensely in volume in a few moments. Drops of rain
fell when they passed. Up to this point the sight had been curious but
not terrifying, but suddenly now, one of these fireballs, about two
feet in diameter, burst open near the traveller and emitted streams
of a bright and beautiful light in every direction, and there was a
dull report followed by a tremendous crash. The two men were much
shaken and the air all round them seemed polluted. After a minute or
two, however, all trace of the explosion had been dissipated, and they
proceeded on their way."

On January 6, 1850, near Merlan, about six in the afternoon, a
fireball burst above the heads of two men, enveloping them in a bluish
light, without hurting them or even damaging their clothes, but giving
them a momentary thrill as from an electric battery. It left no traces
of any kind, not even a smell.

Mr. G. M. Ryan records an instance which he witnessed at Karachi in
Scinde. While in his drawing-room one day with two friends who were
taking refuge from a storm, he rose from his chair and went to the
door to open it, the windows as well as the door being shut at the
time. Returning, he saw in the air and between his friends, a ball of
fire of about the size of a full moon. At the same time there was a
terrible clap of thunder. Two of the spectators were slightly wounded;
one felt a sharp pain on the left side of the face, the other, a
sensation in one arm with a feeling as if his hair were burning. There
was a strong smell of sulphur. In the next room there were two rifles
in a case; one was intact but the other was broken, and there was a
hole in the wall at the point where the muzzle leant against it, and
there were two holes in the same wall a story higher.

On Sunday, August 19, 1900, several people were assembled in a room in
the château of the Baron de France at Maintenay (Pas-de-Calais), when
there was a violent storm raging over the country.

Suddenly there appeared in the midst of the eleven people who were
there, a globe of blue fire about the size of an infant's head, which
quietly crossed the room, touching four people on its way. None of
them were injured. An awful explosion was heard at the moment when the
electric ball disappeared through an open door in front of the great
staircase.

On August 3, 1809, a fireball struck the house of a Mr. David Sutton,
not far from Newcastle-on-Tyne. Eight people were having tea in the
drawing-room when a violent clap of thunder knocked down the chimney.

Immediately after they saw on the ground, at the door opposite the
fireplace, the brilliant visitor which announced itself in the
sonorous voice of Jupiter the thunderer. It remained discreetly at the
entrance of the room, no doubt waiting for the sign to advance. No one
making a move, it came into the middle of the room, and there burst
with a crash, throwing out fiery grains like aeroliths.

The spectacle must have been magnificent--but, we must acknowledge,
rather disquieting.

On September 27, 1772, at Besançon, a voluminous fireball crossed over
a corn-shop and the ward of a hospital full of nurses and children.
This time again the lightning was merciful--it spared nurses and
children, and went and drowned itself in the Doubs.

Nearly thirty years before, in July, 1744, it showed the same regard
for an honest German peasant woman. She was occupied in the kitchen
superintending the family meal, when, after a terrible clap of
thunder, she saw a fireball the size of a fist come down the chimney,
pass between her feet without hurting her, and continue on its course
without burning or even upsetting the spinning-wheel and other objects
on the floor.

Much frightened, the young woman tried to escape; she threw herself
towards the door and opened it, when the fireball at once followed
her, played about her feet, went into the next room, which opened
out-of-doors, crossed it, and through the door into the yard.

It went round the yard, entered a barn by an open door, climbed the
wall opposite, and reaching the edge of the roof, burst with such a
terrific noise that the peasant woman fainted. The barn at once took
fire and was reduced to cinders.

Towards the middle of the last century, March 3, 1835, the steeple of
Crailsheim was set on fire by lightning. The guardian's daughter, aged
twenty years, was at this moment in her room and had her back turned
to the window, when her young brother saw a fireball enter by the
window-sill and descend on to his sister's back, giving her a sudden
shock all over her body. The young girl then saw at her feet a
quantity of small flames, which went towards the kitchen, the door of
which had been opened, and set fire to a pile of mossy wood. There was
no further damage than this attempt at incendiarism, which was easily
extinguished.

Occasionally a fireball seems to take a malignant pleasure in hurling
itself like a fury against lightning conductors; but instead of
quietly impaling itself like the linear lightning, and breathing its
last sigh in a prolonged roar, it struggles, and comes forth
victorious from this curious contest.

There are many cases of fireballs playing about the lightning
conductors without being caught.

In 1777, a fireball shot from the clouds on to the point of the
lightning conductor on the Observatory of Padua. The conductor, which
consisted of an iron chain, was broken at its junction with the stem.
However, it sent on the discharge.

Some years later, in 1792, a huge ball of lightning struck one of the
two conductors on the house of M. Haller at Villiers la Garenne. This
conductor was much injured by the audacious assailant, and so was the
framework of the house; the keen fluid had damaged the metallic
gutters.

At this point I must add that lightning conductors are of recent
creation. Nor would it be surprising if there were defective ones
which could not assure an efficient protection.

However, much later, on December 20, 1845, the same phenomenon was
observed at the château of Bortyvon, near Vire. There, again, the
fireball, ignoring the danger to which it was exposing itself, flung
itself on a lightning conductor placed in the centre of the château.
It was spared, but the château suffered greatly. The electric ball
descended from both sides of the metallic stem, causing a great deal
of damage along its path. On touching the ground it expanded, and many
persons affirm that they saw what was like a huge cask of fire rolling
along the ground.

In truth, ball lightning seems in a certain measure to escape the
influence of lightning conductors.

On September 4, 1903, towards ten o'clock in the evening, M. Laurence
Rotch, director of the Observatory of Blue Hill (U.S.), happening to
be in Paris, made the following curious observation from the
Rond-point of the Champs Elysées.

Looking in the direction of the Eiffel Tower, he saw the summit of the
edifice struck by white lightning coming from the zenith. At the same
moment a fireball, less dazzling than the lightning, slowly descended
from the summit to the second platform. It appeared to be about one
yard in diameter, and to be situated in the middle of the tower,
taking less than two seconds to cover a distance of about 100 yards.
Then it disappeared. The next day the observer ascertained, on
visiting the tower, that it had actually been struck by lightning
twice on the previous day.

It is to be noted that the meteor did not follow the conductor; but,
after all, is not the whole tower itself the most powerful conductor
imaginable? Would not the enormous masses of iron used in its
construction neutralize the attraction of the thin metallic rods,
effectual for the protection of ordinary buildings, but incapable, one
would think, of competing with the attractive force of this immense
metallic framework?

Here are some cases where globular lightning has struck bells or
telegraph wires, which it has followed with docility.

Several times it has been seen poised like a bird on a telegraph wire
near a railway-station, and has then quietly disappeared.

[Illustration: THE EIFFEL TOWER AS A COLOSSAL LIGHTNING CONDUCTOR.

We see that it is not absolutely inimical to points, nor to metals,
but it prefers its independence, and he must get up early who would
catch it in a snare.

It is an anarchist--it acknowledges no rule.

But we must confess that if spheroidal lightning seems particularly
capricious, it is because we are still ignorant of the laws which
guide it. Our ignorance alone is the cause of the mystery.

We try to discover the enigma in the silence of the laboratories,
where physicians question science without ceasing; we try to reproduce
fireballs artificially, but the problem is complicated, and its
solution presents enormous difficulties.

Hypotheses are not wanting. Some years ago, M. Stéphane Leduc recorded
an interesting experiment, producing a moving globular spark.

When two very fine and highly polished metallic points, each in
affinity with one of the poles of an electro-static machine, rest
perpendicularly on the sensitive face of a gelatine bromide of silver
photographic plate, which is placed on a metallic leaf, the two points
being 5 to 10 centimetres the one from the other, an effluvium is
produced round the positive point, while at the negative point a
luminous globule is formed.

When this globule has reached a sufficient size, you can see it detach
itself from the point, which ceases to be luminous, begin to move
forward slowly on the plate, make a few curves, and then set off for
the positive point; when it reaches this, the effluvium is
extinguished, all luminous phenomenon ceases, and the machine acts as
if its two poles were united by a conductor.

The speed with which the luminous globe moves is very slight. It takes
from one to four minutes to cover a distance of 5 to 6 centimetres.
Sometimes, before reaching the positive point, the globe bursts into
two or more luminous globules, which individually continue their
journey towards the positive point.

On developing the plate, you will find traced on it the route followed
by the globule, the point of explosion, the routes resulting from the
division, the effluvium round the positive point. Also, if you stop
the experiment before the arrival of the globule at the positive
point, the photograph will only give the route to that point.

The globule makes its course the conductor. If during its journey you
were to throw powder on the plate--sulphur, for example--the course it
followed will be marked by a line of little aigrettes, looking like a
luminous rosary.

Of all the known electric phenomena, this is the most analogous with
globular lightning.

[Illustration: PHOTOGRAPH OF THE POSITIVE POLE OF AN ELECTRIC SPARK.]

[Illustration: PHOTOGRAPH OF THE NEGATIVE POLE OF AN ELECTRIC SPARK.]

But the really complicated part of the question is when ball
lightning loses part of its fluidity and becomes a semi-solid body, as
in the following instance:--

On April 24, 1887, a storm burst over Mortrée (Orne), and the
lightning literally chopped the telegraph wire on the route to
Argentan for a distance of 150 yards. The pieces were so calcinated
that they might have been under the fire of a forge; some of the
longer ones were bent and their sections welded together. The
lightning entered by the door of a stable in the form of a fireball,
and came near a person who was preparing to milk a cow; then it
_passed between the legs of the animal_, and disappeared without
causing any damage. The terrified cow raised itself on its hind legs
with frantic bellowing, and its master ran away, frightened out of his
wits, but there was no harm done.

The inexplicable phenomenon was that at the precise moment when the
lightning crossed the stable, a great quantity of incandescent stones
fell before a neighbouring house. "Some of these fragments, of the
size of nuts," wrote the Minister of Post and Telegraphs at the
Academy, "are of a not very thick material, of a greyish-white, and
easily broken by the fingers, giving forth a characteristic odour of
sulphur. The others, which are smaller, are exactly like coke.

"It would perhaps be useful to say here, that during this storm the
thunderclaps were not preceded by the ordinary muttering, they burst
quickly like the discharge of musketry, and succeeded one another at
short intervals. Hail fell in abundance, and the temperature was very
low."

It is only by a semblance of disbelief that one can get the peasants
to tell us the stories of what they pretend to have seen of the fall
of aeroliths during storms. They have christened the uranoliths
"thunder-stones."

These substances have evidently no relation to uranoliths, but they
prove none the less that ponderable matter may accompany the fall of
lightning.

Here are two more examples--

In the month of August, 1885, a storm burst over Sotteville
(Seine-Inférieure); lightning furrowed the sky, the thunder muttered,
and the rain fell in torrents. Suddenly, in the Rue Pierre Corneille,
several small balls, about the size of a common pea, were seen to
fall; these burned on touching the ground, sending out a little violet
flame. People counted more than twenty, and one of the spectators, on
putting her foot on one of them, produced a fresh flame. They left no
trace on the ground.

On August 25, 1880, in Paris, during a rather violent storm, in broad
daylight, M. A. Trécul, of the Institute, saw a very brilliant
voluminous body, yellowish-white, and rather long in shape, being
apparently 35 to 40 centimetres in length, by about 25 in width, with
slightly conical ends.

This body was only visible for a few seconds; it seemed to disappear
and re-enter a cloud, but in departing--and this is the chief
point--it dropped a little substance, which fell vertically like a
heavy body under the sole influence of gravity. It left a trail of
light behind it, at the edges of which could be seen sparks, or rather
red globules, because their light did not flash. Near the falling
substance the luminous trail was almost vertical, while in the further
part it was sinuous. The small substance divided in falling, and the
light went out soon after, when it was on the point of reaching the
tops of the houses. When it was disappearing, and at the moment of the
division, no noise was heard, although the cloud was not far away.

This fact incontestably proves the presence of ponderable matter in
clouds, which is not violently projected by an explosion in the bolis,
nor accompanied by a noisy electric discharge.

We are still far from understanding the interesting problem of the
formation and nature of ball lightning. Instead of denying it, men of
science ought to study it, because it is certainly one of the most
remarkable of the curiosities of atmospheric electricity.

We must begin by finding out the exact facts, which are extraordinary
enough to captivate our attention. The theories will follow.



CHAPTER V

THE EFFECTS OF LIGHTNING ON MANKIND


The destructive work of lightning in every form is immense. A
formidable and invisible world skirts the earth--an enchanted world,
more wonderful than any Eastern legend--an unknown ocean, whose
immaterial presence is constantly brought before us by the most
fearful electric conflagrations.

Even to-day the brilliancy of lightning hides itself from us in the
darkness of impenetrable mystery. But we feel that there is an
immeasurable power, an unimaginable force which rules us.

We are, in fact, but puny beings in comparison with this magic force,
and the ancients were wise when they made the King of the Gods
responsible for the actions of lightning. He alone in His splendour
and sovereignty could exercise such an empire over our modest
planet--above all, over man's imagination.

Science slowly follows the centuries in their ascending march towards
progress. At present our knowledge of ball lightning is limited, and
we have only the principal facts of nature to contribute to the
elucidation of the problem.

In increasing our observations, and in comparing those which are
analogous, we may hope, if not to arrive at an immediate conclusion,
at least to help in the work of discovering what laws govern this
subtle and imponderable fluid.

Here it will strike a man dead without leaving a trace; there it will
only attack the clothes and insinuate itself as far as the skin
without even grazing it. It will burn the lining of a garment, and
leave the material of which it is made intact. Sometimes it profits by
the bewilderment caused by its dazzling light to entirely undress a
person, and leave him naked and inanimate, but with no external wound,
not even a scratch.

We find as many peculiarities as facts.

Some of the actions of lightning remind one of the fantastic stories
of Hoffmann and Edgar Poe, but nature is more wonderful than the
imagination of man, and lightning remains supreme in its
phantasmagoria.

Thunder seems to play with the ignorance of man; its crimes and jests
would have been ascribed to the devil in olden days. We submit to the
effects without being able to determine the cause which directs them.

It would seem as if lightning were a subtle being--a medium between
the unconscious force which lives in plants and the conscious force
in animals. It is like an elemental spirit, keen, capricious,
malicious or stupid, far-seeing or blind, wilful or indifferent,
passing from one extreme to another, and of a unique and terrifying
character. We see it twisting into space, moving with astonishing
dexterity among men, appearing and disappearing with the rapidity ...
of lightning ... it is impossible to define its nature.

At all events, it is a great mistake to trifle with it. It means
running great risks. It resents being interfered with, and those who
try to probe into its domain are generally rather cruelly put in their
place.

It was an indiscretion of this kind which cost Dr. Richmann his life.

He had fixed an insulated iron rod from the roof of his house to his
laboratory; this conducted the atmospheric electricity to him, and he
measured its intensity every day. On August 6, 1753, in the middle of
a violent storm, he was keeping at a distance from the rod in order to
avoid the powerful sparks, and was waiting for the time to measure it,
when, his engraver entering suddenly, he took a few steps towards him
which brought him too near the conductor. A globe of blue fire, the
size of a fist, struck him on the head and stretched him stone dead.

This beginning to the study of physics was hardly encouraging.

The visitations of lightning are so numerous that it would naturally
be impossible to describe them all in this small collection. We must,
therefore, choose among them, but here we encounter a great
difficulty. Among the thousands of _tours de force_ and of dexterity
accomplished by lightning, which should we take and which leave? The
selection is very difficult, as it means leaving out a large number of
curious examples with a good many very interesting observations.

We will choose the most important--those of which the authenticity
appears incontestable, and which contain the most precise details. We
will group together those among them which present points of
resemblance. This approximate classification will give us a
sufficiently complete picture for the harmony of this study.

       *       *       *       *       *

One of the most astonishing actions of lightning is certainly that of
leaving the victim in the very attitude in which he was surprised by
death.

Cardan gives an extraordinary example of this kind.

In the course of a violent storm, eight reapers, who were taking their
meal under an oak, were struck, all eight of them, by the same flash
of lightning, the noise of which could be heard a long way off. When
the passers-by approached to see what had happened, the reapers thus
suddenly petrified by death, appeared to be continuing their peaceful
meal. One held his glass, another was carrying the bread to his mouth,
a third had his hand on the dish. Death had seized them all in the
position which they occupied when the explosion occurred.

We hear of many similar cases to this.

Here is one of a young woman who no doubt was struck by lightning in
the position in which she was found after the accident. It was during
a violent storm on July 16, 1866; she was alone in the house at
Saint-Romain-les-Atheux (Loire), and outside the thunder rolled
fearfully. When her parents came back from the fields, they found a
sad sight. The young woman had been killed by lightning. They found
her kneeling in a corner of the room with her head buried in her
hands; she had no trace of a wound. Her child of four months, who was
in bed in the same room, was only lightly touched.

Quite recently, on May 24, 1904, at Charolles (Saône-et-Loire), a
certain Mlle. Moreau, who lived at Lesmes, was waiting for the end of
a storm in a grocer's shop where she had been making some purchases.
Several people were gathered round the fireplace. They felt a great
movement following a violent clap of thunder. The sensation having
passed, every one prepared to go. Mlle. Moreau alone remained seated,
and did not move. She had been struck by the fluid, which had made a
hole under her right ear and come out by the left!

The petrifying action of the electric fluid is so rapid that horsemen
who have been struck have remained on horseback and been carried a
long way from the place of the accident without being unsaddled.

According to Abbé Richard, towards the end of the eighteenth century,
the procurator of the Seminary of Troyes was coming home on horseback
when he was struck by lightning. A brother who followed him, not
perceiving this, thought that he was asleep when he saw him reeling.
When he tried to awaken him, he found he was dead.

The following observation is very remarkable on account of the special
attitudes preserved by the bodies which had been struck:--

A vessel which was at Port Mahon was struck at the time when the crew
were dispersed over the yards to furl the sails. Fifteen sailors who
were scattered on the bowsprit were killed or burned in the twinkling
of an eye. Some were thrown into the water; others, bent dead across
the yard-arm, remained in the position they had occupied before the
accident.

Often the corpses of people who have been struck have been found
either sitting or standing.

At the approach of a storm a vine-dresser was seated under a nut tree
which was planted near a hedge: soon afterwards, when it had ceased
raining and the thunder was quiet, his two sisters, who had been
taking shelter under the hedge, saw him sitting, and called to him to
go back to work, but he did not reply; on going up to him, they found
him dead.

In 1853, in the neighbourhood of Asti, a priest who was struck while
dining remained in his place.

In 1698, a ship was struck at about four o'clock in the morning, not
far from Saint-Pierre. At daybreak a sailor was found sitting stone
dead at the bow of the ship, with his eyes open and the whole body in
such a natural attitude that he seemed to be alive. He had suffered no
injury either external or internal.

Dr. Boudin describes a still more surprising case. A woman was struck
while she was in the act of plucking a poppy. The body was found
standing, only slightly bent and with the flower still in her hand. It
is hard to understand how a human body could remain standing, slightly
bent, without a support to prevent its falling. This case is a
contradiction to all the laws of equilibrium. But with such a
fantastic agent as that with which we are dealing, nothing is
surprising--we may expect anything. Thus--

On August 2, 1862, lightning struck the entrance pavilion of the
Prince Eugene barracks in Paris just when the soldiers were going to
bed. All those who were lying down suddenly found themselves
standing, and those who were standing were thrown on the ground.

In the preceding examples the victims struck dead are not disfigured
by the fulgurant force. They preserve a deceptive appearance of life.
The catastrophe is so sudden that the face has no time to assume a sad
expression. No contraction of the muscles reveals a transition in the
passage of life and death. The eyes and mouth are open as though in a
state of watching. When the colour of the flesh is preserved, the
illusion is complete. But when we approach these statues of flesh--so
lately animated with vital fire, now mummified by celestial fire--we
are surprised on touching them to find that they crumble to ashes.

The garments are intact, the body presents no difference, it keeps the
attitude it had at the supreme moment, but it is entirely burnt,
consumed. Thus--

At Vic-sur-Aisne (Aisne) in 1838, in the middle of a violent storm,
three soldiers took shelter under a lime tree. Lightning struck them
all dead at one blow. All the same, they all three remained standing
in their original positions as though they had not been touched by the
electric fluid: their clothes were intact! After the storm some
passers-by noticed them, spoke to them without receiving an answer,
and went up to touch them, when they fell pulverized into a heap of
ashes.

This experience is not unique, and even the ancients remarked that
people who were struck crumbled to dust.

Here is a similar case, no less curious--

On June 13, 1893, at Rodez, a shepherd named Desmazes, seeing that a
storm was threatening, collected his beasts and drove them quickly
towards the farm. When he was just there, he was struck by lightning.
His body, which was completely incinerated, preserved a natural
appearance.

It is by this complete incineration and the probable volatilization of
the cinders that certain authors explain the sudden disappearance of
some of those who have been struck.

Legend attributes the mysterious death of Romulus to a similar cause.
According to Livy, the illustrious founder of Rome was reviewing his
army in a plain near the marsh of Capra. Suddenly a storm accompanied
by violent claps of thunder enveloped the king in a cloud so thick
that it hid him from sight. From that moment Romulus was seen no more
on earth.

It is true, Livy adds, that some of the witnesses suspected the
senators of having torn him to pieces: kings have sometimes been
subject to all kinds of surprises on the part of their "courtiers."

In most cases the electric matter produces burns more or less severe.
These, when they do not attack the whole organism as in the preceding
examples, are localized to certain parts of the body. Sometimes they
are quite superficial and only attack the epidermis. Often without
absolute carbonization, they penetrate deep into the flesh and cause
death after the most fearful suffering.

Here are some examples of different sorts of burns--

In 1865, in the Rue Pigalle in Paris, a man had his eyes burnt by
lightning.

A young soldier of the 27th Battalion of Chasseurs was armed, mounting
guard at the Col de Soda. It was in the month of July, 1900. Suddenly
he was surrounded by the dazzling glare of lightning, which was almost
immediately succeeded by an awful explosion of thunder. The sentinel,
leaving his arms, fell backwards screaming. People ran to him, and saw
that the fluid, attracted by the point of the bayonet, had struck it,
and, gliding down, the metal had burnt his feet rather severely.

At Malines, in Belgium, a mill was reduced to splinters by the fire of
heaven. The miller and two of his customers were there at the time of
the accident. Not one of the three men was killed, but the miller was
seriously burnt in the head, on the chin and the cheeks. He was deaf
and blind for twenty-four hours. One of the others was burned in the
hands.

On June 19, 1903, at about six in the evening, during a bad storm,
five farmers were crossing the Champ de Gentillerie near Saint-Servan,
in order to take shelter. Three of them were walking abreast, the two
others, of whom one was leading an ass, were some paces behind, when
suddenly the five men and the ass were thrown on the ground by a
violent clap of thunder. Three of the farmers, recovering their
consciousness after the shock, observed that their two companions were
struck; the head of one was carbonized, and the left side of the other
was burnt as though by a red-hot iron.

Another phenomenon, no less appalling--

A woman who was struck had her leg so horribly burnt that, on removing
the stocking, some particles of flesh adhered to it. From the knee to
the end of the foot the skin was black as though carbonized, and the
whole surface was covered with a species of blister full of a
sero-purulent liquid. The burns were very serious but not mortal, and
were localized in the leg.

Lightning also sometimes produces wounds which are more or less
severe. It perforates the bones. The injuries it causes are similar to
those inflicted by firearms.

It can also cause partial or total paralysis, the loss of speech or
sight, temporary or permanent. Its action is manifold on the human
organism.

A more extraordinary phenomenon still is that people who are struck
show no sign of the slightest injury on a minute medical examination.
The ancients remarked this, as we see in the charming passage from
Plutarch: "Lightning struck them dead without leaving any mark on the
bodies nor any wound or burn--their souls fled from their bodies in
fright, like a bird which escapes from its cage."

We have already spoken of the smell of fulminated air and of ozone. In
some cases there is more than that.

On June 29, 1895, lightning struck a low house at Moulins in the
course of a violent storm. The fluid, eccentric as usual, attacked the
outer chimney, the bricks of which were loose and projected slightly.
It broke some tiles on the roof, the length of one rafter, and inside
the corn-loft it broke the wooden handle of an iron rake to splinters.
On the ground floor, bricks were both loosened and torn out near where
the pipe of the stove went into the wall of the chimney-piece.

A dozen plates were broken in a cupboard to the left of the hearth,
and a woman who happened to be near it at the time of the explosion,
said she had felt her legs warmed by the burning air which came from
the cupboard. The room was afterwards filled with a thick infected
smoke, a veritable poison.

Sometimes the victims are nearly asphyxiated by the fulminic
effluvium, and only owe their preservation to the extreme care which
is lavished on them.

Very often the bodies and the clothes of people who have been struck
give forth a nauseous smell--generally similar to that of burning
sulphur.

In the month of August, 1879, a woman who had been struck at
Montoulieu, in the Champ Descubert quarter, had her skull perforated
as though a big ball had passed through it, and her burnt clothes gave
forth insupportable emanations.

Dr. Minonzio relates how three persons were wounded by lightning on
board the Austrian frigate _The Medée_. "I remember," he says, "the
sensation which was caused in the locality by the stench which came
from the bodies and clothes of these people who were struck--a stench
nearly as offensive as that of burnt sulphur mingled with
empyreumatical oil."

One of the most frequent and good-natured effects of lightning on man
is to shave his hair and beard, to scorch them, or even to depilate
the whole body.

Generally the victim may consider himself lucky if he leaves a handful
of hair as a ransom to the lightning, and escapes with a fright.

There is even a case given of a young girl of twenty who had her hair
cut as though by a razor, without perceiving it or feeling the least
shock.

On May 7, 1885, two men who were in a windmill were struck by
lightning. They were both struck deaf, and the hair and beard and
eyebrows of one were burnt. In addition to this, their clothes
crumbled to the touch.

A man, who must have been very hairy, was struck by lightning near
Aix. The electric current raised the hairs of his body in ridges from
the breast to the feet, rolled them into pellets, and incrusted them
deeply in the calf of the leg.

Very often the injury to the hair, instead of being spread all over
the body, limits itself to certain places where it is thicker or
damper on the body of a man, and more especially on that of a woman.
Here are some curious examples.

In Dr. Sestier's learned work, vol. ii. p. 45, we read the following
case observed at Montpellier:--

"Accidit apud Monspelienses ut fulmen cadens in domum vicarii
generalis de Grassi pudendum puellae ancillae pilos abraserit ut
Bartassius in muliere sibi familiari olim factum fuisse."

Toaldo Richard has described similar experiences, and d'Hombres Firmas
has described several others:--

A number of people were assembled at Mas-Lacoste, near Nîmes, when
lightning penetrated to where they were. A girl of twenty-six was
thrown over and became unconscious; when she came to her senses, she
could hardly support herself or walk, and felt a great deal of pain
in the centre of her body. When she was alone with her friends, they
examined her, and they saw "non sine miratione pudendum perustum
ruberrimum, labia tumefacta pilos deficientes usque ad bulbum
punctosque nigros pro pilis, inde cutim rugosissimam; ejus referunt
amicae primum barbatissimam et hoc facto semper imberbem esse."

Lightning is indeed a joker, but so it has always been.

In most cases the hair grows again, but sometimes the system is
completely destroyed, and the victim must either wear a wig or go
bald.

We have already spoken further back of the case of Dr. Gaultier, of
Claubry, who was struck one day by globular lightning, near Blois, and
had his beard shaved off and destroyed for ever; it never grew again.
He nearly died of a curious malady, his head swelled to the size of a
metre and a half in circumference.

We also hear of corpses of people who have been struck, which show no
other injury than a complete or partial epilation.

For example, a woman who was struck in the road had the hair
completely pulled out of the top of her head.

On July 25, 1900, a farm servant, Pierre Roux, was killed while in the
act of loading a waggon of hay. The only trace the lightning left
behind it was to completely scorch the beard of its victim.

Now, here is a case the complete opposite of the preceding ones and
still more curious, in which the capricious and fantastic lightning
attacked the epidermis without burning the hair which covered it.

At Dampierre thunder broke over a house belonging to M. Saumois. His
arm, one leg, and the left side of his body were burnt, and the
extraordinary thing is that the skin of the arm was burnt leaving the
hair intact.

A little further on we shall have cases where the lightning has proved
salutary in certain forms of illness.

Generally the people who are struck fall at once without a struggle.

It has been proved by a great number of observations that the man who
has been struck by lightning so as to lose consciousness immediately
falls without having seen, heard, or felt anything. This is easy to
believe, since electricity is animated by a movement much quicker than
that of light, and still more so than that of sound. The eye and ear
are paralyzed before the lightning and the thunder could have made an
impression on them; so much so that the victims, when they recover
themselves, are unable to explain what has happened to them.

People struck by lightning nearly always sink on the very spot where
they have been struck. Besides this, we have already remarked several
cases where the people struck have preserved the exact positions they
had at the moment of the catastrophe.

But, on the other hand, we can quote some examples, rarer, but
diametrically opposed to these.

On July 8, 1839, lightning struck an oak near Triel (Seine-et-Oise),
and also struck two quarrymen, father and son. This last was killed
dead, raised, and transported twenty-three yards away.

The surgeon Brillouet was surprised by a storm near Chantilly, and was
raised by the lightning and deposited twenty-five paces from where he
had been.

On August 18, 1884, at Namur (Belgium), a man was flung ten yards from
the tree under which he had been struck by lightning.

The following notice was in the papers in August, 1900:--

"Brousses-et-Villaret (Aude), August 20. During the storm which burst
over that region the lightning killed two cows belonging to M.
Bouchère. It also struck, but without hurting him, a young man of
twenty-three years of age, Bernard Robart, artilleryman, who was
taking a holiday. He was walking to a neighbouring farm when he was
suddenly carried through the air for fifty yards. He got up again
without any hurt, only he was dazzled by the lightning which had
flashed before his eyes."

On writing to the victim to verify this fact, I received the following
answer:--

     "I have the honour to inform you that the article relating to
     the incident which happened to me during the lightning, on
     the 17th, is absolutely true.

     "I was on leave at Brousses, Canton of Saissac (Aude). I left
     my uncle's house at about 8 p.m. There had been a heavy
     storm. The rain had nearly stopped for about two or three
     minutes, but it still fell a little. There had been a good
     deal of thunder during the storm. I was sleeping at home, the
     house being about two hundred yards away. It was very dark,
     and seeing that the rain was going to begin again with
     violence, I started to run. I went very quick. I was crossing
     the Place, and when I arrived in front of M. Combes' house, I
     suddenly felt myself stopped, and without being able to
     explain how, I found myself in the same instant at the other
     side of the Place, lying on the ground against the wall of M.
     Maistre's house. I was astounded; I waited a good minute
     without knowing where I was. When I got home I felt a severe
     pain in the right knee, and I perceived that my trousers were
     torn and that I had a big scar on my knee, and that my hands
     were slightly scorched. It must have happened against the
     wall where there were some loose stones. I was transported
     about fifty yards, and I cannot tell you if it thundered at
     the same time, but there had been a big clap about a minute
     before. Two people who were leaving M. Combes' house were
     witness of the fact. The lightning penetrated into M.
     Bouchère's stables two hundred yards away, and killed two
     cows and broke the leg of another. As it went in it broke the
     cover of the doorway, which was of freestone, in two, and
     knocked over a chair and seven or eight bottles which were on
     a shelf.

         "Believe me, etc.,

                "BERNARD ROBERT,
                "Artilleryman, Fort Saint Nicholas,
                "Marseilles."

Thus we have several examples of people being transported 20, 30, and
50 yards from the point where the lightning has struck them.

Sometimes the bodies of people who are struck are as stiff as iron and
retain their stiffness.

On June 30, 1854, a waggoner, thirty-five years of age, was struck in
Paris. The next day Dr. Sestier saw his corpse at the Morgue: it was
perfectly stiff. The next day, forty-four hours after the death, this
stiffness was still most marked.

Some years ago, in the Commune of Hectomare (Eure), lightning struck
a man named Delabarre, who was holding a piece of bread in his hand.
The contractility of the nerves was so strong that it could not be
taken from him.

On the other hand, the bodies very often remain flexible after death,
as in life.

On September 17, 1780, a violent storm burst over Eastbourne. A
coachman and footman were killed. "Although the bodies remained from
Sunday to Tuesday unburied," remarked an observer, "all their limbs
were as flexible as those of living people."

Sometimes the corpses soften and decompose rapidly, leaving an
unbearable odour.

On June 15, 1794, lightning killed a lady in a ballroom at Fribourg.
The corpse rapidly gave forth a curious odour of putrefaction. The
doctor could hardly examine it without fainting. The inhabitants of
the house were obliged to go away thirty-six hours after the death,
the odour was so penetrating. It was with difficulty that they were
able to put the fetid corpse into a coffin. It fell to pieces.

The flabbiness often observed in the bodies of people who are struck
is due, no doubt, to the fact that in the case of enormous discharge,
the stiffness of a dead body develops so quickly, and is of such a
short duration, that it may escape observation.

Numbers of experiments made on animals justify this hypothesis.

Nevertheless, in the majority of cases, bodies which have been struck
decompose rapidly, which explains quite naturally the softness of
bodies killed by lightning.

The colouration of these presents numerous varieties; sometimes the
face is of a corpse-like paleness, at others it preserves its natural
colour.

In many cases, the face is livid, red, violet, violet-bronze, black,
yellow, and even covered over with brown or blue spots.

The colouration of the face may be extended over all or nearly all the
body.

The eight reapers who were killed under an oak, quoted by Cardan in
our first example, were quite black.

That the subtle fluid accumulated in great masses in the clouds should
kill a man, deprive him of movement, annihilate his faculties, or
slightly wound him--this ought not to astonish us when we contemplate
the marvellous results and the prodigies of strength accomplished by
the much more feeble electricity of our laboratories.

But the extraordinary point about lightning is its variety of action.
Why does it not invariably kill those it strikes? and why does it
sometimes not even wound them?

There are inexplicable subtleties in the world.

One knows of many examples of people who are struck whose garments
remain absolutely intact. The imponderable fluid insinuates itself
through the garments, leaving no trace of its passage, and may cause
grave disorders in the body of a man without any exterior mark to
reveal it to the most perspicacious observer.

We hear of the case of a man who had nearly the whole of his right
side burnt from the arm to the foot, as though it had been for a long
time too near a quick fire, but his shirt, his pants, and the rest of
his clothes were untouched by the fire.

The Abbé Pinel gives the case of a man who, amongst other injuries,
had his right foot very badly lacerated, while the left was untouched;
the right sabot was untouched, and the left was broken.

On June 10, 1895, at Bellenghise, near Saint-Quentin, a lady was
killed under a tree: she had deep marks of burning on the breast and
stomach, but her clothes remained intact. Lightning is very
mystifying.

Th. Neale cites a case where the hands were burnt to the bone in
gloves which remained intact!

At other times, garments, even those nearest the skin, are perforated,
burnt, and torn, without the surface of the skin being injured.

Thus the boot of a man who had been struck was so torn that it was
reduced to ashes, while there was no trace of a wound on the foot.

An extraordinary case in point happened at Vabreas (Vaucluse) in July,
1873. A peasant was in the fields when there was a violent clap of
thunder. The electric fluid struck his head, shaved the left side, and
completely burnt his hat. Then, continuing its route, it tore his
garments, penetrated the length of his legs, and tore his trousers
from top to bottom. Finally, it transported the unfortunate man,
nearly naked, six or seven yards from his original place, and laid him
on his stomach on a bush with his head hanging over the edge of a
river.

Sometimes, when the garments are seriously injured, we find slight
injuries under the skin which do not always correspond to the places
where the garment is most seriously affected.

Lichtenberg quotes the case of a man who had his clothes cut as by the
point of a knife from the shoulders to the feet, without the sign of a
wound except a small sore on the foot under the buckle of the shoe.

According to Howard, a man had his clothes torn to atoms without
showing any trace of the action of the electric fluid on the surface
of his body, except a light mark on the forehead.

Sometimes, as we have already said, the inner garments are burnt while
the outer ones are respected.

A woman had her chemise scorched by the fire of heaven, while her
dress and petticoats were spared.

On June 14, 1774, lightning fell at Poitiers in a yard where a young
cooper was working. It went under his right foot, burning his shoe,
passed between his stocking and leg, singed the stocking without
wounding the leg, burned the lining of his trousers, raised the
epidermis of the abdomen, tore off a brass button which fastened his
garment, and went off to twist a carpenter round in a neighbouring
lane. Neither one nor the other felt the effects of this stroke of
lightning.

Finally, the clothes, above all the shoes, are unsewn carefully and
without a tear, as though by the hand of a clever workman.

Here are two cases in a thousand--

On June 18, 1872, at Grange Forestière, near Petit-Creusot, a man had
his trousers unsewn from top to bottom and his shoes taken off.

In the department of Eure-et-Loire, some peasants were engaged in
binding sheaves, and their daughter, aged nine, was playing near them
when a storm broke with great violence.

"Let us go in, I am frightened," she cried, running to take refuge
between her parents.

"We will go in immediately, but we must finish binding before the rain
comes on."

"Then I will beg of the Good God to keep the thunder from us."

"Do."

And while the father and mother continued their work, the child went
down on her knees, and with her hands over her eyes commenced her
prayer.

Suddenly, without hearing or seeing anything, the father felt the
straw move under his feet; he turned mechanically, and gave a great
cry on seeing his little daughter stretched motionless on the ground.
She was dead. Her little corset was unsewn and her chemise burnt.

But of all the fantastic actions of lightning, the most extraordinary
and incomprehensible is the mania it has for undressing its victims,
and leaving them dead or fainting in the primitive costume of our
first parents--or in a dress too simple to be allowed by our civilized
customs.

This deplorable and quite inexplicable habit has given lightning a
large scientific _dossier_, from which we have already cited examples
in the first chapter, and from which we will again extract some
fragments.

Near Angers, on May 12, 1901, a farm lad named Rousteau, aged
twenty-three, was killed by lightning in the middle of the fields. The
corpse was found nearly naked.

On June 29, 1869, at Pradettes (Ariège), the Mayor was unfortunate
enough to take shelter under a very high poplar. Soon after he had
done so, there was a burst of lightning which split the tree and
struck him. In one of its diabolical freaks it entirely undressed him,
throwing his various garments round about him, reduced to rags, with
the exception of one shoe.

In June, 1903, at Saint-Laurent-la-Gatine, thunder broke over M.
Fromentin while he was working a plough drawn by three horses.
Lightning killed the leader, and completely undressed M. Fromentin
after burning his hat.

The same day, at Limoges, a farm servant named Barcelot was struck
under an oak. His corpse was completely naked and he had a severe
wound on his left side.

On August 20 of the same year, a violent storm burst over the Isle of
Re. A farmer, who was on his way to the station at Finaud, was struck
fifty yards from his own house. The lightning removed all his clothes.

In 1894 the keeper of the Commune of Saint-Cyr-en-Val, near Orleans,
was struck while on his rounds; the fluid deprived him of his clothes
and removed all the nails from one of his shoes.

On July 1903, at Aseras, near Nice, during a violent storm with
hailstones 350 grammes in weight, a Mme. Blanc was on her way to meet
a servant who was in the fields. She had only taken a few steps when
she was struck by lightning and completely undressed. Her body was
uninjured, but the poor woman became dumb.

How fantastic and extravagant it is! It is impossible to assign any
rule to the capricious advance of lightning.

How are we to explain the following facts of nature?

One night in April, at about 6 p.m., near Ajaccio, a peasant named J.
B. Pantaloni was leaving the fields and hurrying home to escape from a
storm. He had hardly reached his house when it was set on fire by an
electric discharge, and the unfortunate man was killed dead and
carbonized. At the same time his two sons and a daughter, who were in
the same room, were completely undressed and their garments
disappeared. These last were not hurt in any way.

Very often clothes, which have been torn and tattered, are taken a
long way off.

On October 1, 1868, seven people were seeking shelter under an
enormous beech near the village of Bonello in the Commune of Perret
(Côtes-du-Nord), when, suddenly, lightning struck the tree and killed
one of them. The six others were thrown to the ground without being
much hurt. The clothes of the one who had been struck were reduced to
tatters; several of these were found hanging on the branches of the
tree.

One day a workman was sheltering under the shed of a kiosque in which
there were five men playing cards. He was grazed by lightning. The
fluid, after having passed between the players without hurting them,
left the kiosque, and removed a shoe from the poor workman, who was
petrified with fright. They searched for the shoe which had been
confiscated by the fulminant matter, but in vain.

Moreover, lightning seems to have a special predilection for shoes; it
seldom respects them, even when it spares the other garments. Sabots,
shoes, and even boots are removed, unsewn, un-nailed, cut to pieces,
and thrown far away with extraordinary violence. Very often the
discharge penetrates into the human body by the head and leaves it by
the feet.

During a violent storm (June 8, 1868) a workman was passing near the
Jardin des Plantes, when he felt a great oppression on his stomach. He
was then knocked down roughly by an irresistible force, and deprived
of the use of his senses at the moment of the fall. He was picked up
and taken home, and on being examined, his body bore no trace of a
wound, and he escaped with a fright. But some days after, when he had
recovered from the shock, he remembered that he had worn boots at the
time of the accident. These had disappeared, the lightning had stolen
them from him, though it acted from a distance. The boots were found
in the street, and the soles had the nails completely removed,
although they were screwed in and the boots were nearly new.

On May 31, 1904, at Villemontoire (Aisne), a workman was killed on a
hay-cock, his clothes were reduced to fragments, and his shoes were
not to be found. Two other workmen were wounded, and the cock was set
on fire.

On May 11, 1893, lightning broke over the Commune of Chapelle-en-Blezy
(Haute-Marne). A young shepherd, who was watching his flock in the
fields, was knocked over by the fluid and lost consciousness. When he
came to himself he found that his sabots and cap had disappeared.

Arago states that a workman was struck under a pavilion, and that the
pieces of his hat were found embedded in the ceiling.

Biot gives the case of a hat which was flung ten paces without a
breath of wind.

We could multiply these very curious observations, but we must
restrain ourselves so as to remain within the limits of this little
book. Did I not say just now that lightning has sometimes--though very
rarely--exercised a beneficial influence on sick people it strikes?

Yes; we hear of several cases where thunder has shown itself a rival
to the noblest disciples of Esculapius, and where it has worked
veritable miracles.

For instance, a person who had been paralyzed thirty-eight years,
suddenly, at the age of forty-four, recovered the use of her legs,
after a stroke of lightning.

A paralytic had been taking the curative waters of Tunbridge Wells for
twenty years, when the spark touched him and cured him of his terrible
infirmity.

Lightning has sometimes worked marvels on the blind, deaf, and dumb,
to whom it restores sight, hearing, and speech.

A man who had the whole of his left side paralyzed from infancy was
struck in his room on August 10, 1807. He lost consciousness for
twenty minutes, but after some days he gradually and permanently
recovered the use of his limbs. A weakness of the right eye also
disappeared, and the invalid could write without spectacles. On the
other hand, he became deaf.

Indeed, if we are to believe stories which appear to be authentic, a
cold, a tumour, and rheumatism have been cured by lightning. We have
given an example in our first chapter.

It is impossible to explain in what manner the subtle fluid
accomplishes these wonderful cures. Are they to be attributed to the
shock, to a general upheaval which brings back the circulation to its
normal course? Or are we to attribute to the electric substance--still
unknown to physicians and physiologists--an action capable of
overcoming the most inveterate evils?

The science of Therapeutics already makes excellent use of the
electricity of the machines. Can we, then, marvel much that lightning
should rival our feeble electric resources? No! What a number of
services might it not render if it were not for its mad independence!
What an amount of lost power there is in the gleam of lightning!

As a matter of fact, we owe no gratitude to lightning. There are too
many miseries for a few happy results. The balance is really too
unequal.

Some lightning strokes have proved veritable disasters, on account of
the number of the victims and the havoc which has been caused.

The most extraordinary of these are the following:--

On a feast-day lightning penetrated into a church near Carpentras.
Fifty people were killed or wounded or rendered imbecile.

On July 2, 1717, lightning struck a church at Seidenburg, near Zittau,
during the service; forty-eight people were killed or wounded.

On June 26, 1783, lightning struck the church of Villars-le-Terroy,
when its bells were being rung; it killed eleven people, and wounded
thirteen.

On board the sloop _Sapho_, in February, 1820, six men were killed by
a stroke of lightning and fourteen seriously wounded.

On board the ship _Repulse_, near the shores of Catalonia, on April
13, 1813, lightning killed eight men in the rigging and wounded nine,
of whom several succumbed.

On July 11, 1857, three hundred people were assembled in the church at
Grosshad, a small village, two miles from Düren, when lightning struck
it; one hundred people were wounded, thirty of them seriously. Six
were killed, and they were six hardy men.

Early in July, 1865, lightning fell on the territory of Coray
(Finisterre) in a warren where sixteen people were weeding. Six men
and a child were killed by the same stroke, and three others were
severely wounded. Several were stripped naked, their garments being
scattered in rags over the ground; their shoes were cut to pieces and
all broken. A curious point is that the workers were struck at a
distance of 100 yards from each other.

On July 12, 1887, at Mount Pleasant (Tennessee, U.S.A.), lightning
killed nine people who were taking refuge under an oak during a storm.
These formed part of a procession which was conducting a negress to
her last home.

Here is another very curious and complex case--

On the last Sunday in June, 1867, during Vespers, lightning struck a
church at Dancé, Canton of Saint-Germain-Laval (Loire). A deathlike
silence succeeded the noise of the explosion, then a cry was heard,
then a hundred more. The curé, who thought that he alone had received
the whole electric discharge--and was in reality unhurt--left his
place, where he was enveloped in a cloud of dust and smoke, and spoke
to his parishioners from the Communion rails, to reassure them. "It is
nothing," he said. "Keep your places; there is no harm done."

He was mistaken; twenty-five to thirty people had been more or less
struck. Four were carried away unconscious, but the worst treated of
all was the treasurer. In raising him they perceived that his eyes
were open, but dull and veiled, and he gave no sign of life. His
clothes were burnt, and his shoes, which were torn and full of blood,
were removed from his feet.

The Monstrance, which had been exposed, had been thrown down on the
ground, and was battered and pierced in the stem, and the Host had
disappeared. The priest searched for it for a long time, and finally
discovered it on the altar in the middle of the corporal, on a thick
bed of rubbish.

Three or four yards of the wainscoting of the choir had burnt into
atoms. Outside, the arrow of the belfry had been carried off, and its
slates were scattered about in the neighbouring fields.

On June 22, 1902, lightning struck, the church of Pineiro (Province of
Orense, Spain) during a funeral. There were twenty-five dead and
thirty-five severely wounded.

These are cases of destruction on a large scale, but we can give
parallel cases where the terrible fluid seems only to amuse itself.

In fact, some people appear to enjoy the privilege of particularly
attracting lightning, and of frequently receiving its visits without
suffering much from its reiterated attacks.

They say that Mithridates was twice touched by lightning. The first
stroke was when he was in his cradle, his swaddling clothes were
singed, and the scar of a burn which he received on his forehead was
covered with hair afterwards.

According to the Abbé Richard, a lady, who lived in a château on an
elevation near Bourgogne, saw the lightning several times enter her
room, divide itself into sparks of different sizes, of which the
greater part attached themselves to her clothes without burning them,
and left livid traces on her arms and even on her thighs. She said,
when speaking on this subject, that thunder had never done her more
harm than to whip her two or three times, though it fell pretty often
on her château.

There seems to be a sort of relative immunity in women and children.
These are seldom struck. We have even several examples of children
remaining safe and sound in the arms of their mothers who are struck.

Fracastor's mother had her child to her breast when she was struck by
lightning. The child itself was spared.

In August, 1853, at Georgetown (Essex), Mrs. Russel, wife of the
Protestant minister, was killed by lightning, while a small child
which she had in her arms was unhurt.

It would seem as if lightning pitied the feeble--the women and
children.

We hear of cases where people were struck several times during the
same storm without succumbing to its manifold attacks.

"In two similar situations," says Arago, "one man, according to the
nature of his constitution, runs more risk than another. There are
some exceptional people who are not conductors to the fulminating
matter, and who neither receive nor pass on a shock. As a rule, they
must be ranked among the non-conductor bodies that the lightning
respects, or, at least, that it strikes rarely. Such decided
differences could not exist without there being finer shades. Thus
each degree of conductibility corresponds during the time of a storm
to a certain degree of danger. The man who conducts like a metal will
be struck as often as a metal, while the man who cuts off the
communication in the chain, will have almost as little to fear as if
he were made of glass or resin. Between these limits there will be
found individuals whom lightning might strike as it would strike wood,
stones, etc. Thus, in the phenomena of lightning, everything does not
depend on the place that a man may occupy; his physical constitution
will have something to do with it."

The phantasmagoria of lightning leaves us perplexed. All these
observations are extraordinary and very disconcerting. The facts
contradict each other, and lead us to no actual conclusion.

The _Gazette de Cologne_ gave the following case in June, 1867:--

At Czempin, a young girl of eighteen was struck by lightning while she
was working near a hearth. She remained unconscious, in spite of all
the efforts made to revive her. At last, acting on the advice of an
old man, they placed her in a freshly dug ditch, and covered her body
with earth, but in such a way as to avoid stifling her. After some
hours she recovered consciousness, and was restored to health.

Sometimes lightning amuses itself nicely and innocently. It mixes in
the society of men without doing them harm, or leaving any remembrance
but a great fear.

One day lightning entered by the chimney into the middle of a lively
dance at M. Van Gestien's, the innkeeper at Flone (Belgium). At the
sight of it the dancers were petrified with terror, and not one could
try and escape. But they misunderstood the intentions of the
lightning, which were of the most straightforward; it only wanted to
be a spoil-sport. It also had the good taste to depart quietly.

After the first excitement a profound stupefaction seized hold of the
persons present; they were all transformed into niggers. The lightning
had swept the chimney, and cast the soot into the ball-room, powdering
all the faces and toilettes.

Lightning might be the daughter of goblins rather than a messenger
from Olympus. The following facts might confirm this impression:--

At Bayonne, on June 6, 1873, lightning knocked over a gas-burner, and
threw a person down, after making her turn round three times. A family
of twelve were gathered together at a table, sixty yards, at least,
from the point where it burst. They were all knocked down, but without
sustaining any injury.

During a violent storm, lightning entered a country house by the
chimney; it lifted two big stones from the hearth, and carried them
over to near the head of a child who was asleep, and placed one on
each side, without grazing it or hurting the child.

And this same lightning, whose almost maternal delicacy is quite
exquisite, entered another time, also by the chimney, into a house,
hit a man savagely on the head, wounded him severely, and left him
dead in the middle of a pool of blood. Then it took a quantity of this
blood which was accumulated round his head, and went and stuck it on
the ceiling of the higher story. A child who was present at this
tragic scene was unhurt.

In August, 1901, an electric spark penetrated into a house in the
village of Porri, near Ajaccio, and started to make the tour of the
property. First it visited the second-floor rooms, without doing much
damage there; then it went down to the first floor, where there were
two young girls, turned them round, and burnt their legs. It continued
on its course as far as the cellar, where its dazzling brightness
terrified three young children who had taken refuge there. It spared
two, but burned the third rather severely.

Let us finish this series of electric pictures, which
depict--sometimes in a very tragic manner--the different modes of
activity of one of the grandest of Nature's phenomena, by two facts,
the strangeness of which surpasses everything that one can imagine.

Pliny gives the case of a Roman lady, who, having been struck by
lightning during her confinement, had a stillborn child, without
herself suffering the least harm.

Another:--

The Abbé Richard, in his _Histoire de l'Air_, gives a more
extraordinary case still. At Altenbourg, in Saxony, in July, 1713,
lightning struck a woman who was expecting her confinement. She was
delivered some hours afterwards of a child who was half burnt, and
whose body was all black. The mother recovered her health.

We can neither define nor delimit the power of lightning. Sometimes
merciful, often cruel, it constitutes in the universality of its
actions, one of Nature's most terrible scourges.



CHAPTER VI

THE EFFECTS OF LIGHTNING ON ANIMALS


Animals, even more than mankind, attract the fire of heaven. Lightning
has a certain regard for human beings, which it seems to lose entirely
when it is a case of the humble and faithful servants that Nature has
given us.

And, between ourselves, thunder is not always as absurd as it appears.
Its proceedings are sometimes even very tactful. Though it may often
strike innocent victims blindly and ferociously; yet it seems at times
to show a certain amount of intelligence. Thus we find among our many
examples a strange fact, which will serve to reconcile our thoughts a
little to thunder.

On June 20, 1872, in Kentucky State, we have already cited the case of
the nigger Norris, who was going to be hanged for the murder of a
mulatto companion, and who, just as he was putting his foot on the
fatal platform, was struck by lightning, and thus spared the sheriff
the trouble of hurling him into eternity.

Here was a case where thunder was full of justice, and we cannot
praise it too much.

Arago gives another case where a chief of brigands was shut up in a
Bavarian prison, together with his accomplices. No doubt he was
encouraging their arrogance by his blasphemies--the stone to which he
was attached acting as a tribune for him--when he was suddenly struck
by lightning while haranguing his disciples. He fell dead. The iron
manacles had brought on the disaster, but the brigands did not stop to
think of this natural cause; they were just as terrified as if the
iron had not been there, and the lightning had chosen its victim with
intelligence.

Here is another instance--

The favourite of a prince had obtained from him a written recognition
of her son. She counted on this to give trouble to the State after the
death of her benefactor. She enclosed it carefully in a chest, and
went and buried it deep in a wood, hoping to render all search
useless, if the prince should change his mind.

But behold, the lightning intervened; the tree was struck, and the
open chest was thrown on the highway, where it was found by a peasant.

Animals are worse treated than men, but better than plants and
inorganic bodies. What are the causes of this difference? Can we
attribute it to physical predisposition? But this has not yet been
proved. Experience shows that sparks directed on the vertebral column
are particularly dangerous. Now, the backs of quadrupeds are greatly
exposed to mortal strokes from the celestial fire.

Their fur or their plumage, which form an intrinsic part of their
bodies, put them more or less in the situation of a man who, to
protect himself from inclemency, should envelop himself in his hair,
supposing this to be long enough and rich enough to cover him
decently.

Animals rarely survive when struck. When they do not die on the spot,
they succumb soon after to their wounds. The ancients have remarked on
this.

"Man," says Pliny, "is the only animal that lightning does not always
kill; all the others die on the spot. It is a prerogative granted to
him by Nature, though so many animals surpass him in strength." And,
further on, he adds that amongst birds the eagle is never struck. This
has given it the name of _porte foudre_.

But these assertions are slightly exaggerated, and we can quote a
certain number of examples of animals which have resisted the baneful
influence of the electric current.

In 1901, a horse was touched by lightning, which was certainly
attracted by the iron of his shoe. It traced two deep trails right
along the animal's leg, where the skin was abrased, and appeared as
though it were cauterized. These two lines joined together at the fold
of the ham, and then formed a single furrow, all sign of which was
lost in the abdominal region. The rest of the body was unhurt, and the
animal sustained no further harm after being struck than it would have
done if an incompetent veterinary surgeon had fired him too severely.

On July 4, 1884, at Castres, ten persons and nine horses were struck
by lightning; all survived the accident.

On June 9, 1886, in the Grand Duchy of Luxembourg, three cows and a
little girl, who was in charge of them, were knocked over by a violent
shock. The child and the beasts soon got up. Only an ox was killed
some distance from there.

Very often horses are stunned by the discharge on animals which are
killed, but after a time they recover. This phenomenon has also been
observed in other animals. For instance, five or six pigs which were
in a cage in the prow of a ship were killed by an electric discharge,
whilst others which were only separated from them by a cloth were
saved.

But the cases are rare in which animals do not succumb to lightning.
They nearly always perish. At present we will only discuss animals as
a body, equal, or superior to man. The others, the smaller ones,
offer a still more convincing generality.

All animals seem to be greatly exposed to the wrath of Jupiter;
nevertheless, some species appear to be peculiarly sensitive to
lightning--the gentle sheep, for example, which huddle together
fraternally during a storm, and fall in a mass, struck by the fire of
heaven.

I have before me a list of animals which have been struck. There are
some of every kind. We might divide them thus--

    Several hundred rams, sheep, and ewes.
    73 horses, mares, and colts.
    71 oxen, cows, or bulls.
    9 dogs.
    4 asses.
    3 goats.
    3 cats.
    3 mules.
    2 pigs.
    1 hare.
    1 squirrel.

A prodigious quantity of geese, chickens, pigeons, and small birds.

Fish also contribute a respectable contingent to lightning.

As a rule, large groups of animals are dangerous when there is
thunder, as they seem to exercise a strong attractive influence to the
electric fluid.

Often entire herds are destroyed by lightning. Dr. Boudin gives the
following example:--

On May 11, 1865, at about 6.30 p.m., Hubert Wera, a shepherd who was
surprised in the fields when a storm overtook him, was hurrying home
with his flock. On coming to a narrow and difficult road, the sheep
formed themselves into two groups. The shepherd took shelter behind a
bush, when a terrible clap of thunder was heard. Lightning struck him
and his flock. The unfortunate man was struck on the top of his head.
All his hair had been taken from the nape of his neck, and the
electric fluid had traced a ridge on his forehead, his face, and
breast. His body was quite naked; all his clothes were reduced to
rags. Moreover, there was no trace of blood. The iron of his crook had
been detached from the handle and thrown several yards away, and the
handle itself was broken to pieces. A small metal crucifix and a
scapular belonging to the unfortunate shepherd were found fifteen
yards away.

Of the flock of 152 sheep, 126 were killed. They were covered with
blood, and their wounds were as varied as they were peculiar. Some had
their heads chopped, others had them pierced from side to side, others
had their legs fractured. As to the dog, he was not to be found.

On May 13, 1803, near Fehrbellin (Prussian States), one clap of
thunder killed a shepherd and 40 sheep.

On June 1, 1826, thunder killed 64 hairy beasts in a field at Gulpin
(Limbourg).

At Prades, on July 28, 1890, 340 sheep were struck at one blow.

During a violent storm which burst over Montmaur in the Isère,
lightning struck a flock of 90 sheep, and killed 53.

In the month of April, 1869, thunder burst over a sheepfold in which
there were 80 sheep.

Fifty of these were found entirely carbonized, the thirty others were
covered with sores, on the head, in the eyes, and on the back, and
half asphyxiated by the fulminant fluid. The poor sheep were all
cowering together.

On August 11, 1905, a flock of sheep were carbonized, and cattle of
every kind were struck.

At Limoges, on July 4, 1884, 42 cows or oxen were struck by the spark.
They were all joined together by an iron chain.

On June 24, 1822, near Hayengen (Wurtemberg), a shepherd and 216 sheep
out of 288, were struck in the open field.

Lastly, according to Abbadie, a storm in Ethiopia killed in one single
stroke, 2000 goats and their shepherd. These figures are, I think,
sufficiently eloquent, and if it were not for fear of fatiguing my
readers, who might become bored, we could add a great many similar
examples to this list. But it would be superfluous to expatiate
further on the dangers incurred in a storm by large agglomerations of
animals. In their terror, beasts, particularly sheep, press closely
together, and are soaked by the rain. In this way they offer a large
surface, which absolutely conducts the lightning. Also the column of
vapour which rises from these living masses, affords an excellent
passage for the fluid to pass through while crossing over the bodies
of the poor beasts. It would be better to disperse the flock, rather
than form a compact group of them, during a storm.

One sometimes wonders also what would be the effect of lightning on
animals arranged in a file. Would it act the same with atmospheric
electricity as with that in our laboratories? Would the influence of
the electric matter be more dangerous in the extremities than in the
middle?

When lightning meets a metallic bar, it does no harm except on
entering and departing. On the other hand, when several people form a
chain, holding hands, if the first touches the body of a Leyden
electrical jar and the last touches the top, the whole circle will
instantaneously receive a shock. Only those in the middle receive a
less violent one than those who touch the jar. Well, the discharges
from the clouds produce similar effects on men and animals.

Arago supports this by the following facts:--

At Flavigny (Côte-d'Or), five horses were in a stable when the
lightning penetrated. The two first and the two last perished, the
fifth, which was in the middle, was unhurt.

One day lightning fell on an open field on five horses in a line and
killed the first and last; the three others were spared.

But we should require a much larger number of proofs before we could
be sure of this.

In certain cases, lightning, always fantastic and extraordinary, seems
to make a fastidious choice of its victims. It kills one, spares
another, strikes a third, does good to a fourth--what a strange game!
how fantastic!

Madame la Comtesse Mycielska, of the Duchy of Posen, wrote to me
recently--

"During a storm which took place in the month of August, 1901,
lightning entered by a half-open door into a stable where there were
twenty cows, and killed ten. Beginning with that which was nearest the
door, the second was spared, the third killed, the fourth was
uninjured, and so on. All the uneven numbers were killed, the others
were not even burnt. The shepherd who was in the stable at the time of
the shock, got up unhurt. The lightning did not burn the building,
although the stable was full of straw."

We have given a similar case in the chapter on Fireballs. _A propos_
of this, M. Elisee Duval, of Criquetot l'Esneval (Seine-Inférieure),
relates a very remarkable case. On June 20, 1892, lightning fell on
the telegraph poles of Havre and Étretat. A dozen were thrown over,
and the curious part is that every second one was knocked down.

Here is a more extraordinary case still. We were not aware that
thunder could distinguish between colours, and that it has its
preferences amongst them. Well, we need no longer be surprised at
this. Here we have a case where the fluid declares itself distinctly
in favour of black. It was at Lapleau in Corrèze. One day thunder fell
on a grange full of hay and straw, and covered with thatch, without
setting it on fire. Then it went to the sheepfold and killed seven
black sheep, and left the white alone.

This choice is categorical, and people who fear lightning might follow
this example by wearing long white garments in a storm. Unfortunately,
lightning is so eccentric and uncertain, that we must not defy it; it
is not to be trusted.

Who can explain why it sometimes glides into a stable full of cows
without injuring one? This extraordinary thing happened in the Commune
of Grignicourt (Marne).

After a great clap of thunder, all the cows that were in a shed became
unfastened, without one of them being hurt.

There, again, the lightning only seemed to want to make itself useful.

If, in some cases, by a providential chance, cattle have been saved,
it is none the less true that an animal very rarely survives a
discharge which has caused the death of a human being.

But, as there is no rule without exceptions, we will give the
following:--

The sky was dark and lowering, and a shepherd, seeing that there was
about to be a storm, ran to his flock to drive it to the shed. Just at
the same moment, lightning burst and knocked him down, together with
thirty sheep. The beasts all got up soon, but the poor shepherd was
dead.

On another occasion, on June 13, 1893, a shepherd was killed by
lightning, and the remarkable thing was that only one sheep out of the
hundred of the flock was struck.

On June 17, 1883, thunder entered a sheepfold, containing one hundred
sheep. Only four perished. One of them was marked on the back with a
cross, formed of two rectilinear grooves, penetrating to the skin;
only the wool was removed.

Sometimes, but very rarely, men and animals survive the discharge.

Thus, Dr. Brillouet's horse was thrown into a ditch, and remained
there without moving for three-quarters of an hour, after which he
was able to get up. Later on he became very feeble in the legs.

Very often the same stroke kills men and animals simultaneously. We
have already given several cases of this kind. Here are some more--

A terrible storm burst at La Salvetat, on August 26, 1900. A shepherd
and his flock, composed of twenty-three sheep, were all killed by
lightning.

On June 23, 1887, a young boy, fifteen years of age, living at
Montagnat (Ain), was struck while fastening oxen to the door of a
stable; an ox was also killed.

At Lagraulière (Corrèze), on August 15, 1862, three girls were looking
after their flocks. A violent storm burst at about five o'clock, and
the thunder growled terribly. The shepherdesses, taken by surprise,
had no time to take their flocks in. The two first took shelter under
a big chestnut, the third under an oak twenty-five yards away from
them. Suddenly lightning struck the chestnut and enveloped the two
little refugees. They fell dead. The third fainted, half asphyxiated
by the smell of the sulphur. The clothes of the two unfortunate girls
who had been struck were burnt, their sabots were broken. Near them
there were five sheep, a pig, and a she-ass, which had also been
killed by the fluid. The shepherdess's dog had been cut in two.

Sometimes, also, the clap of thunder, when striking men and animals,
proves more murderous for the latter than the former, who, however,
have sometimes succumbed.

A diligence was slowly mounting an incline, when suddenly a stroke of
lightning interrupted its ascent. An electric ball burst over the
heads of the horses, and threw the whole five down, stone dead. The
postillion was struck, but not one other person was touched, though
the carriage was full of women and children.

There is one peculiarity about this incident which ought to attract
our attention--the terrible meteor was not accompanied by any emission
of light, nor followed by any reverberation of sound.

In June, 1872, at about two in the afternoon, a farmer at
Grange-Forestière was trying a couple of oxen, which he had just
bought at the fair, in a field. Lightning knocked over the man and the
animals. Some hours after, the poor farmer was picked up in a pitiable
plight. His hair was burnt in parts, also hair on his chest, he was
quite deaf, and in a state of absolute prostration. His trousers were
unsewn from top to bottom in all four stitchings, his hat was riddled
with holes, and his shoes torn off. All the same, he survived the
accident. The oxen were killed on the spot.

In fact, as we have already said, when the spark strikes men and
animals at the same time, only the former can resist the shock.

In June, 1855, thunder burst over a flock of sheep in the Commune of
Saint-Leger-la-Montagne (Haute Vienne); seventy-eight sheep and two
watch-dogs were killed on the spot. A woman who was looking after the
flock was slightly touched.

On September 26, 1820, lightning struck a labourer who was driving
near Sainte Menehould. His two horses were killed; the man escaped
with a temporary deafness.

In August, 1852, two out of four oxen were killed, the third was
paralyzed on the left side. As to the farmer, he came off with a
numbness of the left leg.

Very often a man feels nothing, not even a shock, while the animals
beside him fall dead.

Here are some facts--

On February 2, 1859, a herd of pigs were surprised by a water-spout
near Liége. One hundred and fifty of these animals perished by the
action of the electric fluid, their guides felt nothing.

In 1715, lightning fell on the Abbey of Noirmoutiers, near Tours, and
killed twenty-two horses without doing any harm to 150 monks, whose
refectory it visited and upset the 150 bottles containing their ration
of wine.

In the year IX., lightning killed a horse and a mule near Chartres,
sparing the miller who conducted them.

On July 17, 1895, four cows were going along a road, when suddenly
they were pushed and thrown roughly to the edge of the road. The old
drover who was with them felt nothing except the sensation of a strong
and very characteristic odour which he could not define.

In 1812, a fulgurant discharge took place near Mr. Cowen's and killed
his dog beside him, without doing him any harm.

In August, 1900, lightning penetrated into a cart-shed, where twelve
chickens were taking shelter. The poor things were killed, but a lady
who was feeding them was unhurt.

One often asks if lightning strikes birds in flight. This question, so
often put, would seem to find an answer in the following facts:--

A lady was looking out of her window, when there was a flash of
lightning, accompanied by a great clap of thunder. At the same time
she noticed on the grass a dead gull which she had not seen before.
The people who picked up the bird, affirmed that they found it still
hot, and they added that there was a strong smell of sulphur.

Examples of this kind are rare: we have two more--

One day, Mr. W. Murdochs with two friends was looking on at a very
violent storm, which spread itself over the Valley of the Ayr. Just
then his dog dislodged a flock of ducks which had been sheltered
behind an old building. One of the birds began to fly, and as it was
cutting through the air, it was struck by lightning and killed as
though by a gun.

During a storm in the United States, Mr. Burch saw a flock of wild
geese flying by. Suddenly there was a flash of lightning which threw
the flock into disorder; six birds fell dead to the ground.

One would have thought that the absence of all communication with the
ground ought to protect the graceful winged tribe from lightning; but
no, the poor birds have received no mercy from this terrible
adversary.

All the same, lightning is less redoubtable for them than the
sportsman's gun. It is very seldom that the kings of the air are the
victims of the fire of Heaven, but they have another enemy, barbarous,
unpardonable Man. Yes, the little earthly Jupiters are infinitely more
terrible for the bird-world than the giant of the gods. They are
rarely softened by the seductive grace, the elegance, and the
delightful twittering of the charming inhabitants of space.

In truth, one of the reasons why birds are so rarely struck in their
flight is that they foresee the storm, and have the prudence to take
shelter before it bursts.

Amongst birds, sparrows are those which suffer most from the electric
fluid.

We sometimes find them hanging by their shrivelled claws from
telegraph wires or from the branches of trees. But this latter is
rather rare. They generally nest high in the trees, and lightning
affects the branches much less than the trunk.

We also hear of little caged birds being killed in their iron prison.
One day a canary was in a cage with five others and was killed; the
rest were unhurt. The spark was attracted by the metallic bars, and
struck the canary, which was no doubt resting on iron.

Fishes in their dark dwellings are no more privileged than other
animals. They also frequently receive visits from the lightning, and
their sad fate has often proved how dangerous it is to remain near a
pool or pond during thunder.

Moreover, why are we recommended always to put the conductor into a
well, damp earth, or even into a small pond? It is because water
conducts the electric substance admirably.

We can understand that a vast space of liquid would be a good refuge
for lightning, when, after having made several victims on earth, and
fearing the vengeance of the conductors, it hurls itself into the
water.

More often it drowns itself, and in this it follows the example of the
immortal Gribouille; but enough of that. The logic of lightning is
still contestable.

However that may be, many examples show us the dangers to which the
denizens of rivers, and of the liquid element generally, are exposed.
Not only are fishermen and sailors unanimous in attesting to the
ravages wrought by lightning, but the history of electricity has
preserved the recollection of memorable disasters, of veritable
hecatombs of fish, which they attribute to the fire of heaven.

Arago recounts that on September 17, 1772, lightning fell on the Doubs
and killed all the pike and trout which were in the river. The water
was soon covered with their corpses which floated, stomach upwards.

A century before, during the year 1672, the lake in the subterranean
part of Zirknitz was the theatre of a similar event, even more
terrible, on account of the number of victims. The inhabitants of the
neighbourhood collected such a number of fish that were struck, that
they were able to fill eighteen carts.

In 1879, during a violent storm at night, the electric discharge fell
on a little fish-pond in which a number of fish sported. The next
morning they were all found floating dead on the surface of the water.
They had the appearance of boiled fish, and their flesh fell to pieces
on being touched, just as it would if it had been cooked. There was no
injury to be seen, external or internal. The scales and the swimming
bladder, which was full of air, had been preserved. The water of the
pond remained troubled and muddy the day after the storm, as though
the agitation of the tempest had been quite recent.

Here is an observation, similar to the last:--

In 1894, lightning fell on two poplars near Ignon, in the territory of
Saulx-le-Duc (Côte-d'Or). A neighbouring pond, which measured 10 yards
in length by 5 in width, was also struck. The owner states that all
the fish, to the number of about a thousand, were killed.

Another more curious case still:--

One day the fish in an aquarium placed in a drawing-room were struck.
They were all found lying dead on the floor. The glass which formed
the bottom of the vessel was twisted and coated with a thick bed of
yellowish substance.

If we study the effects of lightning on animals from the point of view
of the injuries which it produces, we can make some very interesting
remarks.

More often the hair of animals is injured or burnt. Sometimes the
spark acts on the skin over a large surface of the body of the animal.
Thus, two horses had their hair singed nearly all over their bodies,
and more particularly on the leg and under the stomach. At other times
the hair is only burnt in certain places.

Lightning struck a young four-year-old ox which was red with white
spots. It burnt and removed all the white spots and left the red
hair.

But generally we find one or more furrows of different kinds. The skin
is seldom intact under injured hair. It is nearly always more or less
burnt. And one often notices extravasations of blood which correspond
to the injuries of the epidermis, in the subcutaneous cellular tissue.

In some cases, the fulminant fluid only attacks the colour of the hair
of the animal.

The fracture of the bones or the ablation of a limb is often observed
on animals which have been struck.

In 1838, a violent storm broke near Nimegue, and several oxen were
killed in the meadows and their bones were broken.

In the month of May, 1718, in the Marche de Priegnitz, eight sheep
were struck. They could not be used as food, because all their bones
had been broken as though in a mortar, and the fragments were
intermingled in the flesh. These, however, remained intact.

We have seen in the preceding chapter that fulguration often leaves no
particular sign on men who are struck. It is the same with animals.
The electric fluid entirely absorbs the source of life and only leaves
insignificant traces of its passage. Sometimes even we can find no
exterior injury.

On July 7, 1779, near Hamburg, lightning killed two horses in their
stable. They showed no exterior trace of a burn, though both had a
rupture of the auricles.

In the month of September, 1787, at Ogenne, two cows and a heifer were
struck in their stable; no exterior wound was to be found on their
bodies.

Another observation is given by the Abbé Chapsal in his remarkable
description of the effects of lightning. A pig fell dead, struck by a
clap of thunder, and no indication could be found of the electric
passage.

We see that lightning does not always make a great distinction between
the blows which it inflicts on men and those which it inflicts on
animals.

Sometimes, also, the corpses of beasts which are struck are completely
incinerated. At the first sight, the body appears intact, but when you
touch it, it falls to pieces.

At Clermont (Oise) on June 2, 1903, several animals were entirely
carbonized in their stable.

We have also heard of animals being transported by the meteor a long
way from the place of the catastrophe. Others have suffered from grave
nervous troubles, following on the strokes of lightning which they
have received. Sometimes partial or total paralysis results. Thus, a
cow which had been struck by lightning, was knocked over, and remained
a quarter of an hour motionless, after which it was seized with
violent convulsions, then it got up quickly looking terrified.

Here is a case of a severe shock which brought on an access of
delirium.

In the course of a terrible storm on September 4, 1849, a butcher,
accompanied by a dog, took refuge under a beech at the edge of the
road. Suddenly lightning fell on the tree and struck the dog, which
became mad, and threw itself on its master, bit him in the thigh, and
only let go when the butcher dragged the animal with him into a
neighbouring house and cut his tail. The dog died in the night.

There are some examples of injuries wrought on animals which are
barely perceptible. For instance, when it makes a transparent horn,
opaque, and when it burns the mucous membrane of the nose.

On the other hand, the foetus which sleeps under the frail covering of
the egg, is exposed to the pitiless blows of the most terrible meteor,
as is the baby in its mother's womb. Chickens have often been struck
before they ever saw the light of day.

Often the noise of thunder, and the fear which results from it, causes
the miscarriage of hinds, and particularly of lambs.

An animal which has been struck generally sinks instantly, without a
struggle. All the same, we hear of the case of a horse which was
struck by the flame, and which struggled for a long time against an
inevitable death.

The corpses of animals, like those of men, are sometimes very rigid;
at others they are soft and flaccid, and decompose rapidly.

Thus all the sheep of a flock which were together under a tree in
Scotland, were killed by a great clap of thunder. The next morning the
owner, wishing to get some advantage out of their remains, sent his
men to skin them, but the bodies were already in such a state of
decomposition, and the stench was so abominable, that it was
impossible for the servants to execute his orders. They hurried to
bury the sheep in their skins.

On September 10, 1845, at about 2 p.m., lightning fell on a house in
the village of Salagnac (Creuse). Amongst other accidents it killed a
pig in a stable; three hours after the body was completely decomposed.

When animals are killed, not by the atmospheric fluid, but by the
lightning of our machines, decomposition always comes on very rapidly.

Brown Sequard made the following very curious experiment on this
subject:--

He took the hearts away from five rabbits of the same kind, the same
age, and about the same strength. He put one aside without touching
it, and he submitted the four others to the passage of an electric
current, of a different strength for each animal. Here are the
different results obtained--

The first animal became rigid after ten hours, and its rigidity, which
was excessively marked, lasted eight days. The rigidity of the four
others was feebler, and lasted a shorter time in proportion to the
strength of the electric current. Thus, the one which received the
weakest current, became rigid at the end of seven hours, and this
lasted six days. The one which received the strongest current became
rigid in seven minutes, and its body softened after a quarter of an
hour.

This experiment explains the absence, or the shortness in duration, of
corpselike stiffness in subjects which have been subjected to the
terrible discharge of lightning.

Animals are not only the frequent victims of lightning, but, as this
experiment shows, they are still oftener the martyrs of science.
Laboratories are sometimes transformed into small cemeteries, where
lie poor guineapigs, frogs which have been quartered, and mutilated
rabbits. But what is the ordinary lot of these last when science
spares them? The chief point is not to let the innocent victims
suffer.

Can we eat with impunity the flesh of animals which have been struck?
Several people say Yes, many say No. Both are right.

Putting aside the question of the rapid putrefaction to which these
bodies are nearly always subjected, the flesh of animals killed by
fulguration has often been found unhealthy and uneatable.

A veterinary surgeon who was commissioned to examine the bodies of two
cows and an ox which had been struck in a stable, declared that their
flesh could not be eaten without danger.

On the other hand, Franklin recounts how some people ate fowls which
had been killed by the electric spark--"this funny little
lightning"--and cooked immediately after death. The flesh of these
capons was excellent and particularly tender, and the illustrious
inventor of lightning-conductors concluded by proposing that we should
follow this proceeding in order to ensure our fresh meat being as
clean as possible when served at table.

We think, however, that it is more prudent to sacrifice the meat which
has been struck, as it has been proved that in certain cases the
decomposition is very rapid.

Up to now we have seen all animals, man included, as victims of
lightning: it is the general rule.

Nevertheless, we often meet beings in this world, men, animals, or
plants, which try to distinguish themselves from others by some sort
of originality. This appears to be the case with the electric fish,
whose existence seems to be dedicated to the worship of Jupiter.

These curious fish have received the gift from Nature of being able to
hurl lightning to a certain distance.

This is how they set to work. A little fish in search of food goes too
near this terrible enemy, who at once sets his living tail in motion.
Fascinating it with his eye, he renders it immovable, and lets fly
repeated discharges to it. After a minute, the poor fish is overcome,
and allows itself to be snapped up by its pitiless adversary without
resistance.

Certain rivers in Asia and Africa and the depths of the Pacific Ocean,
in which these curious animals live, are often the scenes of terrible
dramas, caused by the presence of these lightning fish, which are
divided into five species: the tetrodon, the trichiure, the silurus,
the raie torpille (cramp-fish), and the gymnote (electric eel). These
aquatic lightnings work terrible havoc among the inhabitants of
Neptune's kingdom. They use their influence over men as well as fish.
If you touch a torpille, you feel a shock strong enough to benumb and
paralyze the arm for some minutes.

A curious experiment was tried: eight people formed a chain, and one
of them, with a piece of metallic wire, touched the back of a torpille
which had been imported. They all felt the shock.

If thunder had elected to be domiciled anywhere but in its own
clouds, it would seem as if it would be in the organism of these
curious fish.

Unfortunately, in our international relations, humanity has invented a
much more dangerous torpille (torpedo)!



CHAPTER VII

THE EFFECTS OF LIGHTNING ON TREES AND PLANTS


Nearly two thousand years ago, Pliny wrote, "As regards products of
the earth, lightning never strikes the bay tree." And this is why the
Roman emperors, in fear always of the fire of heaven, crowned
themselves with laurels. This belief was almost universal in ancient
times, and survived for many centuries.

But every new century has proclaimed the immunity from lightning of
some one member of the vegetable world, though impartial research has
now established the fact that there is no such absolute privilege. If
certain trees are rarely struck, that is, perhaps, due less to its
species than to its size, its hygrometrical condition, and to other
influences which it is still difficult to specify; for lightning, as
we have seen, has capricious habits which we have not yet succeeded in
explaining.

Thus the bay tree has lost its proud position in this respect, and has
had to take its place amongst the ordinary run of trees, subject to
the unjust anger of Jupiter. Many bay trees of some size have been
seen to fall victims to the electric fluid.

The fig tree, the mulberry tree, and the peach tree have also been
reputed to enjoy safety, but this also is not the case. There is an
instance on record of a fig tree being struck by lightning and
completely withered, and another of a mulberry-tree, eighty years old,
being partly destroyed.

In our own days, the beech is believed to go uninjured. In the State
of Tennessee, in the United States, the opinion is so deeply rooted
that beech tree plantations are often resorted to as a refuge in times
of storm. But it would be a mistake to place too much trust in them.
There are records of beech trees being struck by lightning and
destroyed, just like bay trees, fig trees, and the rest.

In 1835, an old beech tree was struck in the forest of
Villers-Cotterets. This venerable patriarch was more than three
hundred years old. Of its upper branches, which were wide and strong,
four of the finest were destroyed; a fifth, stripped of its bark to a
great extent, was not torn off the trunk. The trunk was split where
the other four branches were torn from it. The interior of it was
blackened and slightly carbonized.

On July 15, 1868, at Chéfresne, canton de Percy (Manche), an oak and
an ash were struck by lightning within five minutes of each other.

On August 10, 1886, at Haute-Croix, in Brabant, an ash was struck and
destroyed. On August 23, in the same year, an ash was struck also at
Namur.

The box tree and the Virginian creeper used to be regarded as
safeguards against lightning. The same virtue was attributed to the
house-leek, a thick herbaceous plant, which grows usually upon walls
and roofs, and which the Germans call Donnerblatt or Donnerbarb,
Thunder-leaf or Thunder-beard.

According to some authors, again, lightning never strikes resinous
trees, such as pines or firs. But this also is disproved by the facts,
especially in regard to firs.

Among the many particulars I have collected of recent years, is the
following list of sixty-five different kinds of trees, with the record
of the number of times each species has been struck by lightning
within a given period:--

    54 oaks.
    24 poplars.
    14 elms.
    11 walnut trees.
    10 firs.
    7 willows.
    6 pine trees.
    6 ash trees.
    6 beech trees.
    4 pear trees.
    4 cherry trees.
    4 chestnut trees.
    3 catalpas.
    2 lime trees.
    2 apple trees.
    1 mountain ash.
    1 mulberry tree.
    1 alder.
    1 laburnum.
    1 acacia.
    1 pseudo-acacia.
    1 fig tree.
    1 orange tree
    1 olive tree.
    0 birch.
    0 maple.

Height obviously accounts for a good deal. It is incontestable that,
in the case of a clump of trees standing in the middle of a plain,
lightning will in most cases pick out the tallest. But this is not an
absolute rule. The isolation of trees, their qualities as conductors,
the degree of moisture in the soil in which they are rooted, their
distance from the storm clouds, the character of their foliage and of
their roots--all these things are important factors.

Numerous experiments have been made with a view to ascertaining the
amount of resistance offered to the electric spark by different kinds
of wood. Similar pieces of beech and oak have been exposed lengthwise
to the electric spark given out by one of Holtz's machines, with the
result that the oak wood was pierced by the electric fluid after one
or two revolutions of the machine, whereas for the beech wood a dozen
or twenty were needed. Black poplar wood and willow offer a moderate
resistance: a few revolutions suffice to penetrate them.

In all instances the susceptibility of the wood depends on the sap. It
has been proved by analysis that the woods which contain starch with
but little oil, such as the oak, poplar, willow, maple, elm, and ash,
offer much less resistance to the electric current than those trees
which are richer in fatty matter, as the beech tree, walnut tree, lime
tree, birch tree, and so on.

These conclusions are corroborated by the case of the pine tree, the
wood of which has a great quantity of oil in winter, but in summer
lacks it as much as those trees which contain more starch.

Experiments have proved that in summer this wood is quite as likely to
serve as a conductor as the oak; while in winter its resistance to the
electric spark equals that of the beech and other trees which are
rarely struck by lightning. Decayed trees are excellent conductors of
electricity; those in full vigour being much more rarely struck.

In any case, it has been proved that the effects of lightning are
particularly severe in the vegetable world. It has been pointed out
elsewhere in this little book to what dangers those persons are
exposed who take shelter beneath the trees during a thunderstorm;
there are innumerable examples of the imprudence of taking refuge from
the rain under thick foliage, people having been killed by a
fireball--for lightning does not always take the trouble to make a
selection, sparing neither the protector nor the protected.

We shall give some more instances, chosen from a considerable number
of similar observations.

In 1888, ten reapers, surprised by drops of rain and distant rumbling
of thunder, left their work and took refuge beneath a big walnut tree.
But one of them having questioned the security of this retreat, all
immediately fled in the direction of a neighbouring wood, except one
young girl of fourteen years. Several who returned to advise her to
follow them, saw her smilingly throw her arms round the trunk of the
tree, and almost at once fall backwards, her arms extended. She was
dead.

On the 22nd of August in the same year, four labourers, returning from
work, were overtaken by a thunderstorm. Three of them stopped under an
elm, the fourth prudently continued on his way. Well it was for him.
Several minutes later, the lightning struck the tree, killing two of
the labourers outright, and grievously wounding the third. The latter
was found almost completely naked; his garments, burnt and tattered,
were scattered round him. When he came to himself, he was in such a
violent delirium that it was necessary for several men to bring the
unfortunate victim to his home, where he died shortly afterwards in
the most horrible agony.

About six o'clock, on the 23rd of June, seven men employed on the farm
of Puy-Crouel, were working in a field of beet-root. Overcome with the
heat, they went into the shade of a walnut tree. All at once, a flash
of lightning illumined the sky; the seven workmen were thrown down,
one of them being hurled several yards away. Three of them were able
to get up and go to the farm, the others were severely burnt, and half
asphyxiated. One of the victims had his back skinned the whole length
of the vertebral column; the other had his face scratched, as if torn
by fingernails. All had lost their memory. The walnut tree under which
they had sheltered was cleft from top to bottom.

Here is another example no less terrible--

Seven children, belonging to Ahrens, were caught in a thunderstorm as
they were coming home from the fields, and took shelter under a tree.
The lightning killed the seven little people.

Another time, four young men taking refuge under an oak, were struck
and thrown down. One of them was killed instantly, his companions were
cruelly injured.

On the 10th of July, in Belgium, a woman gathering cherries was killed
on a tree which attracted the fluid. A young man standing beneath it
was paralyzed.

We might multiply these tragic tales; each year a number of similar
cases happen. The imprudence of human beings is truly incorrigible!

Everybody, however feeble his instinct of self-preservation, should
flee the vicinity of trees during a thunderstorm, and allow himself
to be drenched on the road, rather than offer his life as a too
generous burnt-offering to the lightning, for the oak's robust trunk,
or that of the poplar, elegantly plumed with its graceful foliage, may
be the altar on which the sacrifices in honour of Jupiter are made.

The wood of trees is not so good a conductor of electricity as the
human body. For this reason, a person leaning against a tree receives
the full discharge; at times the tree is splintered, because it did
not serve as a perfect conductor.

Yet the conductive power of certain species is so remarkable, that the
neighbourhood of particular trees may be regarded as a protection
against lightning (this, however, without coming in contact with
them!).

The tips of the branches pointing towards the clouds, and the moisture
they receive, undoubtedly influence the electricity of the atmosphere;
and, moreover, by means of these graceful branches, an inaudible but
continual exchange is effected between the electricity of the earth
and sky, thus holding the balance between two opposite charges.

Colladon asserts that poplars planted near houses may, in favourable
conditions, act as lightning conductors, on account of their height
and powers of conducting. He adds that it is necessary to take other
circumstances regarding the situation of the dwelling into account,
which are not always easy to define. Their protection of the
neighbourhood is not constantly the same. For it to be effectual, the
foliage should be very low, and they should be at least two metres
distant from the roof and walls. Their roots, too, should be in a damp
soil, and metal should not enter largely into the construction of the
neighbouring houses. In these conditions, poplars may fulfil the
useful functions of lightning conductors.

At times, during a storm, several trees are struck by the same flash.
For instance, on May 23, 1886, in Belgium, three poplars were blasted
by a single thunderbolt.

On the other hand, trees planted in lines are sometimes struck
alternately. A case occurred where the lightning seemed to have taken
aim and touched all the odd numbers in a row without striking the
others.

Certain plantations act on the fluid with an extraordinary intensity.

At Lovenjoul, in Belgium, a wood of undergrowth and big trees, planted
in marshy ground, seems to possess this singular privilege, and the
agriculturists of the country declare that no storm ever passes their
way without lightning falling there. In the middle of this wood one
can count seven oaks, near to one another, struck by it. Not far off,
a huge ash, and a little farther away two poplars, likewise blasted.

All the trees have not been struck in the same way; some are scorched
or stripped of their leaves; the others have their trunks perforated,
or split in different parts. Usually trees are cleft from top to
bottom; in some cases the furrow is horizontal or perpendicular in the
direction of the branches.

Pieces of bark or of wood are sometimes torn off lengthwise, and only
adhere to the trunk in strips here and there. But that does not prove
conclusively that the lightning struck upwards from the ground; it may
have rebounded (?) after striking from above.

Certain effects, however, can only be explained by an ascending
movement of the fluid. The following cases for example:--

"During the summer of 1787, two men were sheltering under a tree at
Tancon, Beaujolais, when they were struck by lightning. One of them
was killed on the spot, the other felt no ill effects other than
momentary suffocation. Their horses were caught up to the top of the
tree. An iron ring which bound the wooden shoe belonging to one of the
men, was found hanging from a high branch of the same tree. Now, at a
little distance, there was a tree which had also suffered greatly by
the passage of the electric fluid. In the soil at its base a round
hole was to be seen, shaped like a funnel. Directly above it the bark
had been loosened and slit into slender thongs. As for the tree
beneath which the men had sheltered, it also had half its bark off,
and long splinters were to be seen hanging only by the upper parts. On
one side of the tree the leaves were withered, on the other they were
still quite green."

In this most remarkable instance the lightning had come out of the
ground.

In the cleft of a willow tree blasted by lightning its roots were
found.

Besides, the soil is often undulating, and thrown up around trees
which have been struck.

Vegetables do not always succumb, any more than men, to these attacks.
They may be lightly struck in a vital part, in which case they recover
from their wounds. Very often they are merely stripped of their
natural garments, in other words, of their bark and foliage. This is
one of those superficial injuries to which they are most subject.

The following is an example of this kind of fulguration:--

On July 16, 1708, two oaks were struck at Brampton. The larger
measured about ten feet around the base. They were both split asunder,
and the bark peeled off from the summit to the soil, a length of
twenty-eight feet. Completely detached from the trunk, it hung in long
strips from the top.

Boussingault witnessed the destruction by lightning of a wild pear
tree at Lamperlasch, near Beekelleronn. At the moment of the explosion
an enormous column of vapour arose, like smoke coming out of a chimney
when fresh coal has been put on the fire. The lightning flashed in all
directions, great branches gave way, and when the vapour cleared off,
there stood the pear tree, its trunk a dazzling white: the lightning
had taken the bark completely off. Sometimes the bark is only
partially stripped off one side, or left on, in more or less regular
bands, either on the trunk or on the branches.

During a violent storm at Juvisy, on May 18, 1897, an elm five hundred
metres distant from the Observatory was struck by lightning, which
took the bark off lengthwise in a strip, four centimetres wide and
five centimetres deep. This band of bark was cut clean off. There was
no trace of burning.

Sometimes only the mosses and lichens are whisked off the sides of the
trees, which escape with light scratches. Two great oaks which had
been struck by fireballs, only bore traces of two punctures which
might have been made by small shot.

Moreover, it is not uncommon to see the bark riddled with a multitude
of little holes, like those made by worms.

Two men were struck by lightning near Casal Maggiore on August 15,
1791, beneath an elm tree. One of them had his elbow on the tree at
the moment, and amongst other injuries were a number of little holes
in the arm. There was a twist in the tree at the part where the elbow
rested, and a hole penetrated the centre of it to the core of the
wood. The surrounding bark looked as if it had been mite-eaten.
Several scars started from this point and ascended almost
perpendicularly towards the top of the trunk. There was no damage done
to the branches.

Lightning cut through a chestnut tree, five metres high, on the
roadside at Foulain (Haute-Marne), burning several leaves, then struck
some water-pipes at a depth of a metre and a half, and finally passed
into the dike through two holes a metre deep by a decimetre in
diameter.

The bark is often reduced to thin splinters scattered on the soil, or
hanging from the neighbouring trees, or even thrown to a considerable
distance.

On June 25, a fireball fell near Jare (Landes) on a pine tree, which
it shivered into a myriad slender strips, about 2 metres long, many of
which were caught on the branches of pines within a distance of 15
metres. Only a stump, 2-1/2 metres in height, remained standing. At
the same time three other pines, which stood 18 and 25 metres away
from the first, were destroyed. The bark had been stripped off each,
but only as far as the incision made for extracting the resin.

Furrows, of varying width, and running in different directions, may at
times be seen on trees, some short, others reaching to the top of the
tree, and occasionally to the roots. These marks show the passing of
the lightning.

Sir John Clark has seen a huge oak in Cumberland, at least 60 feet
high and 4 feet in diameter, from which the lightning had stripped a
piece of bark, about 10 centimetres wide and 5 centimetres thick, the
whole length of the trunk in a straight line.

The furrow is not always single, it may be double, and either stretch
in two parallel lines or diverge.

The Chevalier de Louville observed in the park of the castle at
Nevers, a tree struck at the top of the trunk by lightning which,
dividing in three shafts, hollowed three furrows that might have been
made by three rifle shots fired towards the roots. These three furrows
followed the irregularities of the trunk, always slipping, gliding
between the wood and the bark, and curiously enough the former was not
burnt.

But these bands are not invariably straight either; in the above
example they followed the caprices of the vegetable body. They are to
be found oblique in certain cases, but more often they surround the
trunk in long spirals of varying width, showing that the lightning
clasped the tree in the form of a serpent of fire.

Here is an example:--

During a violent storm on July 17, 1895, a poplar was blasted on the
road through the forest of Moladier, 160 metres north-west of the
castle of Valliere. The tree was 25 metres high, and in full leaf from
base to summit; it was struck halfway up by the discharge, and a
spiral furrow 10 centimetres wide twisted round the trunk to the
ground.

I noted a similar case, August 25, 1901.

Lightning struck one of the highest trees in the park at Juvisy, a
magnificent ash, stripping off and destroying the bark where the
electric fluid curved round and round down the full length of the
trunk, which was shattered by the meteor a few metres above the roots.
Enormous fragments lay all round the trunk, some hurled to such a
distance that it was obvious the explosive force of the phenomenon
must have been of extraordinary violence.

I was able to trace the course of the lightning to the foot of the
tree, along its roots to a great depth, by a black furrow.

The tree is not dead. The ivy which clung to it is dead.

The vast and splendid forest of Saint Germain often witnesses the
presence of the lightning, and the magnificent trees which adorn and
beautify this charming and celebrated place are, unfortunately, too
often the victims of these inopportune visitations.

Lightning has no respect for old memories. It demolished with a single
flash a superb giant whose long branches, laden with perfumed leaves,
had given shade to many generations. The splendid tree, which had
survived the severity of several centuries, fell beneath the arrow of
the pernicious fluid. Such was the fate of an oak near l'Etoile du
Grand-Veneur. Struck on the top, its upper branches were violently
torn off.... A spiral furrow beginning at the top ended within a metre
of the ground. But, wonderful to relate, the whole mass of the tree
appeared to have been twisted mightily by a force which worked with so
much power that the tree could never regain its original position. The
fibre, instead of growing vertically, followed the furrow made by the
lightning, and became twisted like a corkscrew. There exist certain
singular trees, the fibre of which grows in spiral fashion, and is
called twisted wood by carpenters and cabinet-makers. Pines and firs
in mountainous countries are fairly often affected in this curious
fashion. One can no more account for it than one can define the cause
of the curved form of some flashes of lightning. One does not know
exactly if they should be attributed to their following the direction
taken by the fibre, or whether, on the contrary, the tree had been
struck in its infancy by a spiral flash, and, submitting to that
influence, continued to grow up corkscrew fashion.

It is most probable that the fall of the thunder-ball on the trees in
this manner is governed by the laws of electricity. We may even note
casually that traces of similar spirals have been remarked on objects
as well as on the dead bodies of those struck by lightning, thus
preserving the ceraunic likeness of the mortal blow.

Other observers, besides, have declared that they saw distinctly the
spiral lightning flash through the atmosphere. But these observations
would need to be confirmed by photographs of indisputable accuracy. In
these circumstances, as in many others, the dark room is worth a
hundred human eyes!

In some cases the curved furrow turns several times. For instance, in
May, 1850, Grebel saw an alder nearly twenty metres high struck by
lightning on the right bank of the Elster below Zeitz. On the lower
part of its trunk were two spiral bands which had carried away bark
and sap-wood, leaving no trace of combustion.

The depth and width of the twist are very variable; at times the
furrow is deeper in the veined parts than at the edges; again it
reaches the core.

Two oaks were struck in June, 1742, in the park at Thornden. One was
marked with a spiral for a length of forty feet to within a little
distance of the ground. The band was five inches wide, but became
narrower as it descended, and was finally no more than two inches
wide. The wood was incised and even torn in places, but the branches
were not hurt. The rest of the bark seemed to have been riddled by
small shot.

All the injuries of which we have spoken (excoriation, stripping off
the bark, furrows), are not necessarily mortal. But there are other
more serious wounds from which the tree rarely recovers. We allude to
deep fissures and breaks produced by lightning. When the fracture
touches only a portion of the topmost part of the tree, the result of
the accident is not necessarily fatal. But this is not always so.

On May 14, 1865, a poplar was split in two by lightning at
Montigny-sur-Loing. One half to the full height continued standing.
The other half was chopped up in small fragments and thrown to a
distance of a hundred metres. These pieces, which were brought to me
by M. Fouché, are so dried up and fibrous that they might be taken for
hemp instead of wood.

In the majority of these cases the tree is split from top to bottom.

On July 5, 1884, in Belgium, a poplar, the biggest of a group of trees
of the same species, was struck and split down its full length.

In the month of August, 1853, on the side of the road from
Ville-d'Avray to Versailles, a poplar of about twenty years old was
cleft from the topmost bough to its roots; one half remained in its
place, the other fell on the road. A black line, about a millimetre
wide, ran down the centre of the tree.

Sometimes the tree is divided into several parts by vertical fissures.
For example, in 1827, near Vicence, a pear tree, three feet in
diameter, was split into four parts, from the top down.

How often one has remarked great tree trunks in the forests, decayed
and desolate, standing sadly, like poor headless bodies? Very often
lightning has been the executioner of these trees.

In the month of May, 1867, in the forest of Fontainebleau, a
magnificent oak, about two metres in circumference, was completely
decapitated by lightning; its branches fell on the ground. The part of
the trunk left standing was barked to the roots and splintered into
fragments of varying sizes. They were scattered on the ground or hung
from the branches of the surrounding trees. Several pieces of
considerable size were hurled more than thirty metres away, much to
the injury of the bark of the trees which they struck.

In numerous cases, the tree struck by lightning is broken in several
places, and fragments of it thrown far and wide.

On July 2, 1871, at the farm of Etiefs, near Rouvres, canton of
Auberive (Haute-Marne), lightning struck an Italian poplar, sixty
years old, thirty metres high, and three metres round at a height of
one metre from the ground, splintering off enough wood to make a heap
sixty-five centimetres round, and fifty centimetres high.

An ash was struck by lightning on July 17, 1895, on the road to
Clermont. This tree, ten metres high, was broken at a point 3-1/5
metres from the ground, and the crown, still hanging by a shred from
the trunk, lay on the embankment. The violence of the explosion threw
pieces thirty centimetres wide and 3-1/2 metres in length, into a
field from twenty-five to thirty metres off.

On July 4, 1884, in Belgium, a willow was reduced to a heap of atoms
on the ground. In March, 1818, at Plymouth, a fir more than a hundred
feet high and forty feet in circumference, the admiration of the
countryside, disappeared, literally shattered into bits. Some
fragments were thrown two hundred and fifty metres away.

One of the most curious effects of lightning is to divide the interior
of the tree into concentric layers, fitting them perfectly one into
the other, but at the same time separating them with extraordinary
precision.

_Arbres roulés_ (thus are the trees called which are victims of this
odd phenomenon), as a rule, do not show any injury on the outside. But
the body, dissected by the electric fluid, soon succumbs.

An oak, twenty-five metres high, having been struck on August 25,
1818, was opened to be examined carefully, and it was stated that the
concentric layers were as detached from one another as the tubes of an
opera-glass.

The fireball sometimes hollows a canal through the centre of the trees
from the top to the bottom, the sides of which are burnt black. The
following is a curious example:--

In June, 1823, at Moisselles, lightning fell upon a great elm, and
striking against an enormous knob, rebounded on to a neighbouring elm
half its own height, pierced it through and through, shivering it to
tatters; the trunk was burst open to the roots, it looked as if it had
been bored through from one end to the other by a red-hot bullet that
blackened and charred it.

Does it not seem as if the lightning plays with the lives of the trees
as with man? It threatens, changes, apparently spares, returns to the
charge and finally annihilates. And this sport is accompanied, at
times, by inconceivable effects.

But records are still more eloquent than reflections: Nature, in her
own mute speech, tells us of a thousand marvels.

Is not the following phenomenon enough to make lightning more
mysterious in its fantastic and varied mode of action?

On the 19th of April, lightning struck an oak in the forest of Vibraye
(Sarthe), cut this tree, measuring a metre and a half in
circumference, at two-thirds of its height, pulverized the lower
parts, strewed the shreds over a circuit of fifty metres, and planted
the upper part exactly on the spot from which the trunk had been
snatched, with all the rapidity of a flash.

Moreover, the annual concentric circles were separated by the sudden
drying up of the sap so effectually, that, the strips only remained
welded together where the knots made too great an obstacle to their
separation.

How was the lightning able to plant in the earth, with such
inconceivable rapidity, the top of the tree where the roots had been?
This is something which no one can explain. It alone is capable of
creating such situations.

But it has done better still! Two years later, in 1868, it took the
opportunity of playing a good trick on two trees of different species,
an English oak and a forest pine, which, without race jealousy,
fraternized in the forest of Pont-de-Bussière (Haute-Vienne). These
two trees were about ten yards apart, and were simultaneously hit by
the explosive matter, and in the twinkling of an eye, their leaves
were changed. The pine needles found themselves on the oak, and the
leaves of the oak went to brighten the austerity of the pine with
their delicate verdure. There was nothing commonplace about the
metamorphosis. Accordingly all the inhabitants went in crowds to the
scene of this miracle to contemplate the unusual spectacle of a
pine-oak and an oak-pine.

And the unexpected happened: both trees appeared to thrive very well
in these new conditions: the pine continued to be agreeably adorned
with its festival foliage, whilst the oak agreed perfectly with the
sombre needles of the pine.

After such marvels, my readers will not be surprised to learn that
lightning sometimes shatters the living wood, or decayed wood, into a
thousand morsels without setting it on fire.

For instance, a bundle of faggots lying on the hearth has been reduced
to atoms by lightning, without any trace of combustion being visible.

A fireball fell on a sheaf of barley in the open field without setting
it on fire, and buried itself in the ground without doing other
further damage.

In certain cases the electric fluid chars wood at varying depths: the
blackened layer is often very slight; sometimes, on the contrary,
combustion is complete.

As for the leaves, they are unhurt as a rule. When they are attacked
they shrivel up; an autumnal shade takes the place of their charming
green tints; they turn brown and dry up quickly.

One of the trees in the Champs-Élysées having been struck, it was
proved that all round it the ground was full of little holes. In two
or three places the bark was raised from beneath; the leaves were
yellow and shrivelled up as parchment would be by the fire; the upper
part remained green. Everything seemed to prove that the lightning
came out of the ground.

At other times the same effect may be observed on the leaves, when the
trunk and roots are apparently uninjured. It is not unusual to see the
tree instantly stripped of its leaves as if by some mysterious power.

The lightning acts also on the roots, as we have seen in the preceding
examples. They have been seen uncovered where the ground was much
disturbed, torn in strips, or cleft in more or less regular pieces.

We see that lightning does not make more ado about exhaling its
baleful breath on the life of plants, than on animals and men. And
moreover, that it often strikes these latter with sudden death without
leaving a trace of its passing, just as sometimes it strikes the trees
without leaving any exterior injury. Now and then life is not
completely extinguished, and little by little the tree recovers its
health. Often the vitality is not changed, one sees the tree which was
struck bear fruit as before the catastrophe.

Has it not been asserted that lightning may exert a benign influence
on vegetation?

This was the opinion of the ancients.

_A propos_ of this, Pliny said, "That thunder is rarely heard in
winter, and that the great fertility of the soil is due to the
frequency of thunder and rain in spring; for the countries where it
rains often and in good earnest during the spring, as in the island of
Sicily, produce many and excellent fruits."

It has been proved in our times that the ancients were right in
extolling rainwater as nourishment for the products of the earth, and
science has discovered the cause to be the presence of great
quantities of nitrogen and ammonia in the thunder-rain and in hail.
Perhaps electricity has a similar effect.

In the neighbourhood of Castres, on April 13, 1781, an old poplar was
stripped of its bark in several places. Now, shortly afterwards it
burst into leaf, although the neighbouring poplars were much later
than it.

The ravages caused in the fields by the electric meteor to forage and
vegetables are sometimes considerable. This is especially so with
grass when cut, to haycocks, ricks of straw, barley, etc. We have a
collection of records of men or animals who, when leaning against
haystacks, were struck.

As a rule the haystack is burnt; sometimes, however, the grass is
simply scattered and thrown to a distance.

In 1888, a very curious occurrence was observed at Vayres
(Haute-Vienne).

The lightning struck a field of potatoes at the village of
Puytreuillard; some of the stalks were burnt to cinders; but most
remarkable of all, _the potatoes were done to a turn_, just as if they
had been cooked beneath hot ashes.

A belief which was very general in ancient times and derived without
doubt from a recollection of the circumstances which were said to
accompany the birth of Bacchus, gave the vine the privilege of
protecting the neighbourhood from the fatal effects of lightning. But
this again is only a legend. The following observation proves it:--

On July 10, 1884, at Chanvres (Yonne), fifty vine-stocks were frizzled
up by lightning.

It used to be supposed, too, that the electric fluid held the lily in
particular respect. But here is a note which shows us that the white
flower is visited by the burning flashes. During a violent
thunderstorm on June 25, 1881, at Montmorin (Haute-Garonne)----But let
M. Larroque, who witnessed the curious phenomenon, describe it: "In a
clump of lilies in my garden," says he, "I see the highest of them
surrounded by a violet glimmer, which formed an aureola round the
corolla. This glimmer lasted for eight or ten seconds. As soon as it
disappeared, I went close to the lily, which, to my great surprise, I
found had been deprived of its pollen, while the surrounding flowers
were laden with it. So the electric fluid must have scattered or
carried off the pollen."

When Jupiter thunders, he still seems to dominate our world, as in the
days when the graceful legends of mythology flourished.

And not only does he work above ground, but, contrary to the belief of
the ancients, his influence extends beneath the soil.

A great number of men were working in the mines at Himmelsfurth on
July 5, 1755. They were, as often happens, working at various points
along the vein of metal, and never dreaming of the events which might
take place on the surface of the ground. All at once they were
conscious of several very violent shocks, given in the oddest and most
extravagant fashion. Some felt the shock in their backs, while their
neighbours received them on their arms or legs. They might have been
shaken by a mysterious invisible hand, stretching now up from below,
now from above, now from the sides of the galleries. One of the
miners found himself hurled against the wall, two others, whose backs
were turned, almost came to blows, each believing that his mate had
thumped him.

The real culprit was the thunder, of whom they might well demand an
explanation of these strange proceedings.

Here is another example which bears out the foregoing:--

On the 25th of May, the watchman on guard at the pit mouth of one of
the principal mines at Freyberg, perceived an electric glimmer run
along the wire rope going to the bottom of the mines, and used by the
miners to exchange signals with the men employed in working the lifts.
Suddenly all the pits were brilliantly lit up. At the same moment the
watchman saw a clear vivid flame shoot out at the other end of the
chain. On this occasion the lightning behaved with due discretion, and
shone through the mine without giving any one the slightest shock.

In vain the monster Tiberius, and the infamous Caligula, sought a
subterranean refuge from lightning. Their impure consciences, laden
with crimes, dreaded the chastisement of heaven. By fleeing from the
lightning flash, they believed themselves saved from death. Lightning
dogs our footsteps, and works even when the criminals believe
themselves in safety. It is conceivable that the ancients should have
dreaded it as an instrument of celestial justice.

Usually lightning strikes the ground with a vertical stroke, but at
times obliquely, when it traces long, horizontal lines. Often the
ground may be seen turned up at the foot of trees which have been
struck, the sod is torn, and stones thrown to a great distance.
Sometimes, too, an excavation may be seen in the ground near the
object struck, of varying breadth and height. This opening may be like
a funnel or hemispherical.

In a case observed on June 6, 1883, at Côte (Haute-Saône), a circular
hole, having a depth of 1·20 metres, has been seen in a dyke on the
declivity of the road, below a coach which was not struck.

Occasionally the hole is but the beginning of a canal, hollowed rather
deeply and perpendicularly in the ground, the sides of which serve as
a sheath to the fulgurite. But before treating of fulgurite tubes,
which constitute the most curious phenomena in the world connected
with lightning, we shall discuss certain remarkable effects observed
on the surface of the ground.

Falling on solid rocks, the electric spark can break them, cut them,
or pierce them in one or more places. Often instead of spoiling or
cutting off pieces of the stone, it covers the surface instantaneously
with a vitreous coat, having blisters of various colours. This
vitrification is often to be seen on mountains.

De Saussure found rocks of schistous amphiboles covered with vitreous
bubbles, like those seen on tiles where struck by lightning. Humboldt
made similar observations on porphyritic rocks at Névada de Toluca, in
Mexico, and Ramond, at the Sanadoire rock in Puy-de-Dôme.

In these cases, the spark, on reaching the surface, melts it more or
less completely over a varying extent, and this fusion, worked upon by
an extraordinary heat, produces a coat having a peculiar appearance,
but in which microscopical analysis finds the elements of the body it
covers.

Thus the vitreous layer deposited over chalk is of chalky origin; that
covering granite is of the nature of granite, etc.

This does not apply to certain deposits found on rocks, and even on
trees, which have been struck by lightning, and which are of very
different origin.

Whilst the former is only the stone in a fused or vitrified condition,
the latter is caused by the presence of foreign bodies, some fragments
of which have been detached by the ray and travel with it. This
transport of solid substances by lightning has often been observed.
Here are two examples of this strange phenomenon:--

On July 28, 1885, at Luchon, on the Bigorre road a passer-by saw
lightning fall twenty yards away from him. Recovered from the shock,
he went out of curiosity to look at the result, and saw the wall at
the edge of the road, the schistous and chalky rocks, even the trees
themselves, coated over with layers of brown. It was certainly a case
of the lightning having effected a deposit. This latter was very
curious. Lines could be traced on it with the finger-nail, it fell to
powder under slight pressure, became soft with gentle rubbing, caught
fire from a candle, and then gave off a resinous odour with much
smoke. What is this resinous matter? That is what no one yet can say.

In the month of July, 1885, on the day following a violent
thunderstorm which had struck the telegraph-office in the station of
Savigny-sur-Orge, I myself picked up a little black powder off the
telegraph poles, which had been left by the lightning, and which had a
sulphurous smell.

The production of this ponderable matter has often been attributed to
bolides, but direct observation proves beyond a doubt that the
electricity carries various solid substances found on earth after a
storm.

Lightning is truly the most venerable of glass-makers. Long before the
most remote peoples of antiquity appeared, whose glasswares encrusted
with marvellous iridescent tones by the passing of the centuries, are
unearthed by scientific excavations, and displayed in national
collections; long before man could have learnt to make use of the
resources of nature, lightning, burrowing in the sand, there fashioned
tubes of glass that hold the hues of the opal, and are called
fulgurites.

The ancients seem to have known of these fulgurite tubes, but we owe
the first precise description and the first specimen of these
extraordinary vitrifactions to Hermann, a pastor at Massel in Silesia.
His fulgurite, found in 1711, is in the Dresden Museum.

Since this discovery, fulgurites have often been sought for and found.
The tubes, contracted at one end, and ending in a point, are to be
seen in sandy soils.

Their diameter varies from 1 to 90 millimetres, and the thickness of
their sides from half to 24 millimetres. As to the length, it
sometimes exceeds 6 metres. Vitrified inside, they are covered outside
with grains of sand agglutinated and apparently rounded as if they had
been subjected to a beginning of fusion. The colour depends on the
nature of the sand in which they have been formed. Where the sand is
ferruginous the fulgurite takes a yellowish hue, but if the sand is
very clean, it is almost colourless or even white. As a rule, the
fulgurites penetrate the ground vertically, Nevertheless, they have
been found in an oblique position. At times, also, they are sinuous,
twisted, or even zigzag if they have met with pebbles of considerable
size.

It is not uncommon for the fulgurite tube to divide in two or three
branches, each of which gives birth to little lateral branches of 2 or
3 centimetres long, and ending in points.

There are also solid fulgurites and foliated fulgurites. The former,
no doubt, had a canal originally, which has been stopped up by matter
in fusion. The latter, instead of being stretched out in cylindrical
form, are composed of slender layers like the leaves of a book.

The scientific museum at the Observatory of Juvisy possesses a very
curious fulgurite which was offered to me some years ago by M. Bernard
d'Attanoux, and found by him in Sahara. It is not a tube ending in a
point. The lightning penetrating the sand, vitrified it on its
passage, and branched irregularly in three principal directions. One
might say it was slag formed by the juxtaposition, irregular and
crumpled, of three blades of vitrified sand, which would be pressed
together by leaving a narrow opening to their central vertical axis.
This fulgurite, which is extremely light, measures six centimetres in
length. It was found in the sand of Grand-Erg, at a depth of several
centimetres. It has been found possible to produce miniature
fulgurites by means of our electrical machines. By adding ordinary
salt to the sand, and directing a strong current into it, complete
vitrification of a tube of several millimetres is obtained.



CHAPTER VIII

THE EFFECTS OF LIGHTNING ON METALS, OBJECTS, HOUSES, ETC.


When lightning strikes the earth, it makes straight for metals. Their
perfect conducting powers place them in the first rank of conductors,
and the innumerable cases of lightning with which they are associated
have gained them a certain celebrity in the annals of thunder.

We know, indeed, the preference of the spark for metals; we know it
nurses a veritable passion for nails, wire, bell-pulls, that it dotes
on rain-spouts, leaden pipes, and telegraph wires, that it is very
feminine in its adoration of jewels, which it sublimates sometimes
with a truly fantastic dexterity.

Now and then lightning deviates from its path, and performs acrobatic
feats, elfin capers to reach the objects it covets. On April 24, 1842,
it struck the church of Brexton, springing on the cross of the steeple
at first and running down the stem, but, arrived at the masonry which
supported it, broke it into pieces; then with one bound it fell upon
a second conductor, whose support was also broken. Finally, it struck
a third conductor much lower down.

The fluid often searches for metals hidden beneath non-conductors,
which it breaks or pierces. It avoids the mattress to pursue the iron
of the bed, glances off the windows to glide over the curtain-rods, or
the lead of the sash. It has been seen to penetrate thick walls to
reach the iron safes hidden behind them.

We have already mentioned the case of the woman who, without having
been killed, had her ear-ring split. Well, we have a certain number of
similar examples to that.

On June 1, 1809, in a boarding-school for young ladies, at Bordeaux, a
gold chain, worn by one of the young ladies, was melted by the
lightning, which left a black indented line in its place, which,
however, soon passed off. The lady was struck, but recovered
consciousness within a few hours, being none the worse. Her slender
chain, worn in three rows round her neck, had been cut into five
pieces. Some of the fragments showed signs of fusion, and had been
carried to a distance.

Other examples, in which the consequences were more dramatic, will
show ladies the dangers of a love of adornment.

On September 21, 1901, during a violent thunderstorm which burst over
the region of Narbonne, a fireball fell in the domain of Castelou. A
young girl of fourteen was fatally struck by the meteor. The gold
chain which she wore round her throat was completely evaporated. There
was not a trace of it to be found.

It is not unusual to see gold chains broken, melted, partially or
completely, in the pocket which had held them.

Thus, lightning melted a watch and chain into a single lump in the
pocket of a man killed on board a passenger boat.

Bracelets, hairpins, and even precious stones are sometimes very
strangely altered.

As for watches, without speaking of the magnetization observed after a
violent electrical discharge, it has been remarked that the movement
became slower. In some cases they stopped short, and marked the exact
instant when the lightning stopped them.

When the ship _Eagle_ was struck by lightning, none of the passengers
were injured, but all their watches stopped at the moment the shock
took place.

At other times there are peculiarities in the works which are
absolutely inexplicable. The following observation, related by Biot,
is a curious case in point.

A young man was slightly struck by lightning in the street of
Grenelle-Saint-Germain. His watch was in no wise hurt outside, but,
although it was only a quarter-past eleven, the hands pointed to a
quarter to five.

Convinced that it was in need of repair, the young man placed it on
his table, intending to take it to the watchmaker; but next day,
thinking he would wind it up to make sure of the extent of the damage,
he saw, to his amazement, the hands moved and kept regular time.

In some instances the case of the watch is seriously injured, while
the works are none the worse.

A man wore a watch with a double cap attached to a gold chain. The
chain was broken, some of the links soldered together. The cap had
been perforated, and the gold spilt in his pocket. The watch itself
had not been altered.

But if lightning sometimes stops the works of watches, it also
produces the contrary effect.

Beyer relates that a flash of lightning, having entered a room and
broken the corner of a glass, set a watch going which had been stopped
for a long time.

I find the following note amongst my papers: "M. Coulvier-Gravier,
director of the meteoric observatory of the palace of Luxembourg, told
me yesterday that on Sunday, April 8, at 9.35 in the evening, a watch
(wound up), which had stopped a week previously, went on at the moment
lightning struck the lightning conductor on the Luxembourg above
these rooms."

Often enough the case is badly injured: the polish is rubbed off the
metal, it is melted, bored through, and even dented, without any trace
of fusion.

A case of the latter is rare. Here is an example, however.

In the month of June, 1853, a man from Aigremont having been killed by
lightning, his silver watch was found in his watch-pocket completely
smashed.

Indeed, one of the most common effects of lightning on watches is the
magnetization to which the various pieces of steel are subjected. We
have a considerable number of records concerning these magnetic
properties. In one case the balance had its poles so well pointed
that, when placed on a raft, it served as a compass.

We may observe, by the way, that clocks and chronometers are sometimes
as much injured also by the spark. It often gives an energetic twist
to the needles, or to the spring for regulating the strokes, or it
even melts the wheel-works, either partially or completely.

It is difficult to form any idea of the various operations of
lightning; here it hurls itself down like a fiery torrent, there it
makes itself so tiny that it can pass through the smallest apertures.

Does it not even slip under women's corsets, melting the busks and the
little knobs which serve to hook them.

It even attacks the various metal articles which set off our garments,
even to the shoe-buckles, buttons, etc.

Keys are, as a rule, very ill-treated by the fire of heaven: they are
twisted, flattened, melted or soldered to the ring from which they
hang.

On May 12, 1890, a man living at Troyes returned to his house while a
violent storm was raging. The moment he put his key into the lock, the
white gleam of a dazzling flash of lightning surrounded him, the ring
holding his keys was broken in his hand, and they were scattered on
the threshold.

At times, too, scissors, needles, etc., are snatched out of the hands
of the workers, and carried some distance off when they are not
reduced to vapour.

At Saint-Dizier (Haute-Marne) in July, 1886, lightning fell on the
workshop of M. Penon, a chain-maker. Five or six workmen were
finishing their work or getting ready to leave.

Entering by the window near which M. Penon--who was absent at the
time--usually worked, the fluid grazed the bellows which were
opposite, and caught up a piece of it, which one would have thought
was cut off with a knife. Turning to the left, and passing behind a
chain-maker, who felt a violent shock, it passed to a heap of chains
which it did not damage much. All the links in a chain of about a
metre long were, however, soldered together; the whole chain seemed
to be galvanized, and the soldering was not easily broken by hand.
Pieces of iron which had been cut and prepared for the manufacture,
were found twisted and soldered together in the same way. Finally the
lightning snatched the iron hoops from a tub, and, returning the same
way, broke a piece of wood from a board, so as to go through the lower
part of a partition, the masonry of which was carried away for a
length of fifty centimetres.

Very often lightning rivals the most skilful cabinet-makers: iron or
copper nails are pulled out of a piece of furniture with a most
amazing skill, without doing any harm to the material they kept in
place. Ordinarily they are thrown far away. Here are two examples of
this curious phenomenon:--

On September 23, 1824, lightning penetrated a house at Campbeltown;
the copper nails in the chairs were pulled out very precisely, without
the stuff being spoiled. Some were conveyed to the corner of a box
standing at the opposite end of the room, others were so solidly fixed
in the partitions, that it was only with great difficulty that they
were pulled out (Howar). At another time, close to Marseilles,
lightning slipped into a drawing-room, one might say, like a robber,
one evening, and pilfered all the nails out of a couch covered with
satin. Then it departed by the chimney through which it had entered.
As for the nails, they were found, two years afterwards, under a tile!

Locks, screws, door-knobs are frequently pulled out by the fluid.

Sometimes metal objects of much larger size, such as forks or
agricultural instruments, share the same fate. Violently torn out of
the hands of their owners, they start upon an aerial voyage, borne on
the incandescent wings of the wrathful lightning.

Workers in the fields have often been warned of the dangers to which
they expose themselves beneath a thundery sky, by carrying their
implements with the point in the air. Each year the same accidents
occur in precisely similar circumstances.

The electric fluid, invited by the metal point which acts like a
little lightning conductor, darts from the clouds upon this centre of
attraction, and runs into the ordinary reservoir by the intermedial
body of the man, who plays the _rôle_ of conductor.

Two labourers were spreading manure in a field, when a storm came on.
It was at the beginning of May, 1901. Obliged to give up work, they
were thinking of returning home. Each carried an American fork over
his shoulder. They had come within 150 metres of the village, when a
formidable burst of flame took place over their heads. Instantly the
two labourers fell, never to rise again.

In 1903 I made notes of several cases of this kind, from which I shall
quote the two following:--

On June 2, a labourer from the hamlet of Pair, commune of Taintrux
(Vosges), aged forty, was sharpening a scythe in an orchard close to
his house. Suddenly a terrific clap of thunder was heard, and the
unfortunate man fell down stone dead.

On the following day, in the same region, at Uzemain, not far from
Epinal, a young man, twenty-eight years of age, went to get grass in
the country. All at once he was struck by lightning, and his horse,
which he was holding by the bridle, as well. The poor fellow had been
guilty of the imprudence of putting his scythe on the cart with its
point in the air.

On May 27, in the Vosges, the lightning fell on a labourer, Cyrille
Bégin, who was driving a cart to which were yoked four horses. The
unhappy man was struck, as well as two of the horses.

Some authorities have attributed a doubly preservative influence to
umbrellas. The first is undoubtedly to shelter us from the rain; the
second, more doubtful, is the gift of preserving us to a certain
extent from the strokes of the terrible meteor. Silk, having the
property of a veritable repulsion to lightning, one might really
believe that umbrellas, whose covers are often made of this fabric,
are protectors against the fire of heaven. But the records which we
possess are not conclusive; if, now and then, the discharge becomes
distributed by means of the ribs, it also very often happens that it
runs along the metal parts of the handle to whatever pieces of metal
may be on the person, finally striking the soil through the human
body.

On July 13, 1884, in the province of Liége, a man and a woman
sheltering under the same umbrella were struck by lightning. The man
was killed instantly. His garments were in tatters, and the soles torn
from his shoes. His pipe was thrown twenty yards away, as well as the
artificial flowers in his companion's hat. The latter, who was
carrying the umbrella, was stunned.

At a season when, as a rule, thunder is not dreaded--December 9, 1884,
to wit--two men, who were walking on either side of a schoolboy
holding an umbrella, were killed by lightning. The child was merely
thrown down, and got off with a few trifling wounds.

In each of these cases, the person who carried the umbrella suffered
less from the electric discharge, but did not escape altogether,
nevertheless. It may be remarked, also, that the chief victims were
just under the points of the frame, and that in all probability the
electricity passed through these points.

The fusion of metals is one of the lightning's most ordinary
performances; it has occurred at times in considerable quantities.

On April 2, 1807, a fulminant discharge struck the windmill at Great
Marton, in Lancashire. A thick iron chain, used for hoisting up the
corn, must have been, if not actually melted, at any rate considerably
softened. Indeed, the links were dragged downwards by the weight of
the lower part, and meeting, became soldered in such a way that, after
the stroke of lightning, the chain was a veritable bar of iron.

How, one asks, can this truly formidable fusion take place during the
swift passage of the electric spark, which disappears, it may well be
said, "with lightning speed."

What magic force gives the fiery bolt from the sky the power to
transform the atmosphere into a veritable forge, in which kilos of
metal are melted in the thousandth part of a second!

Great leaden pipes melt like a lump of sugar in a glass of water,
letting the contents escape.

In Paris, June 19, 1903, lightning broke tempestuously into a kitchen,
and, melting the gaspipes, set fire to the place.

On another occasion, the meteor breaking into the workshop of a
locksmith, files and other tools hanging from a rack on the wall were
soldered to the nails with which the iron ferrules of their handles
came in contact, and were with difficulty pulled apart.

A house at Dorking, Sussex, received a visit from lightning on July
16, 1750. Nails, bolts, and divers small objects were soldered
together in groups of six, seven, eight, or ten, just as if they had
been thrown into a crucible.

"Money melts, leaving the purse uninjured," says Seneca. "The
sword-blade liquifies, while the scabbard remains intact. The iron in
the javelin runs down the handle, which is none the worse."

We could add other examples, quite as unheard of, as those enumerated
by the preceptor of Nero.

A hat-wire melted into nothing, though the paper in which it was
wrapped was not burnt.

Knives and forks were melted without the least injury being done to
the linen which enveloped them, by the presence of the fluid.

These proceedings give proof of exquisitely delicate feelings; it is a
pity the lightning does not always behave in the same way.

Wires, and particularly bell-wires, make the most agreeable playthings
for the lightning, judging from the frequency with which they are
struck.

Sometimes, in the middle of a fearful thunderstorm, the doorbell is
violently rung; the porter rushes to open the door for the impatient
visitor, only to receive a shock of lightning by way of salvo. The
mysterious hand which pulled the bell is already far away; but it has
left its impress on the bell, and the guiding ray follows the metal
wire in all its windings, passing through holes no bigger than the
head of a pin. The wires are often melted into globules, and scattered
around in all directions.

The Abbé Richard has seen globules from a bell-wire fall into coffee
cups, and become embedded in the porcelain, without the latter being
any the worse.

Metal wires supporting espaliers and vines are often compromising to
the safety of their neighbourhood, especially when they are against a
house.

Without renouncing the succulent peach, or the golden chasselas
grapes, propped on espaliers, we ought to see that they are so
arranged that they do not act as lightning-conductors to our
habitation.

In August, 1868, in a farm amongst the mountains near Lyons, lightning
fell at a distance of about fifteen metres from a dwelling where there
were four people; the meteor, conducted by the wire supporting a vine
on a trellis, followed it into the house, and knocked the four people
down.

One could almost believe that lightning takes a certain pleasure in
looking at its diaphanous and fugitive form in the mirrors hung as
ornaments in our drawing-rooms.

In 1889, a very coquettish flash of lightning rushed to a mirror,
breaking more than ten openings in the gilt frame. Then it evaporated
the gilding, spreading it over the surface of the glass, while on the
silvered back the evaporation of this latter metal produced the most
beautiful electric traceries.

Sometimes the tinfoil or pieces of melted glass are thrown to a great
distance; and at times the fusion of the glass is so complete that the
_débris_ hangs down like little stalactites.

As for the gilding of the frames, it is often carefully removed by the
lightning to a distance, and applied to the gilding of objects which
were never intended to receive this style of decoration.

It is just the same with the gilding on clocks, cornices, church
ornaments, etc.

There are innumerable examples coming under this category. Here are a
few:--

On March 15, at Naples, lightning flashed through the rooms of Lord
Tylney, who was holding a reception that evening. More than five
hundred were present; without any person being injured, the lightning
took the gilding clean off cornices, curtain-poles, couches, and
door-posts; then it shook its booty in a fine gold dust over the
guests and the floor.

On June 4, 1797, lightning struck the steeple of Philippshofen in
Bohemia, and went off with the gold of the clock, to gild the lead in
the chapel window.

In 1761, it went into the church of the Academical College in Vienna,
and took the gold from the cornice of one of the altar pillars to put
it on a silver vase.

It seems difficult for lightning to resist the attraction of gildings.
It was reported that when a house in the Rue Plumet in Paris was
struck in 1767, among several frames hanging in a room, the spark only
touched one which was gilt. None of the others were struck.

In spite of this extraordinarily independent behaviour, lightning has
not so much liberty of action as we might be tempted to believe; it
obeys certain laws which are not yet defined, and its gestures,
although apparently wild and capricious, are not the result of
fortuitous circumstances. To allude to it as chance may serve as a
refuge from ignorance, but it does not, any more than we can, explain
the extraordinary phenomena.

Why are certain organic or non-organic bodies visited repeatedly by
lightning? We need not have recourse to magic to explain.

It is simply because they serve as favourable conductors for the fluid.
One of the best-known examples of this kind is that of the church of
Antrasme. It was struck by lightning in 1752. It melted the gold of
the picture frames adorning the sanctuary, blackened the edges of the
niches in which the images stood, scorched the pewter vases enclosed in
a press in the sacristy; then, lastly, it made two very neat holes at
the end of a side chapel, by which it took its departure. The traces of
this disaster were removed with all haste, but twelve years later, on
June 20, 1764, the lightning returned to the charge. It penetrated the
church for the second time, but the most remarkable fact is, that it
worked havoc similar to that done on its first visit. Again the sacred
picture-frames were despoiled of their gilding, the niches of the
saints blackened, the pewter vases scorched, and the two holes in the
chapel reopened. What demon guided the lightning in these scenes of
pillage? The end of the story gives us the clue. Soon after the
catastrophe the use of the lightning-conductor became general
throughout the whole world. The church was put under the protection of
a rod of iron, after the principles of Franklin, and ever since
lightning allows the faithful to pray in peace within the sanctuary,
and has never returned to profane the church at Antrasme.

Such incidents are of fairly frequent occurrence; they give us a
chance of understanding the supposed preferences of lightning.

In the last chapter we shall see curious cases of "galvanoplasty," of
the nature of the following: amongst others, that of a piece of gold
in a purse, which was silvered over with silver taken out of another
part of the purse, through the leather of the compartment.

What a trick of prestidigitation! On our music-hall stages this turn
would have a great success.

But our last word has not been said about lightning. Just a few more.

One of the most curious effects produced on metals, is the magnetic
polarity communicated to objects in steel and iron, no matter what
they be. We have already quoted a remarkable case, that of the
ascending lightning.

A tailor was slightly touched by the spark; the day after the accident
he found his needles were magnetized: they clung closely to each other
as they were taken out of the case.

Another case of magnetization has been recorded, where certain
objects, which were struck by lightning, had power to raise three
times their own weight.

This magnetization is almost always temporary. Examples are known,
however, where objects preserved the magnetic powers that they
acquired in the moment of the shock. And one can understand the terror
inspired by lightning in uncultured minds, when, after the passing of
the meteor, they see common things suddenly animated by a fantastic
vitality, fine needles attract and raise very much larger bodies than
themselves, and impart a feverish agitation to any pieces of steel or
iron that may be placed near them.

What a lively impression these curious phenomena must have made on the
minds of men in the days when sorcery was in fashion, and when
lightning was, according to the belief then popular, at the service of
heaven and hell! But, nowadays, sorcery is fallen into disuse; the
magnetization of metal bodies, even when the result of lightning, is
something too well known to be attributed to any connection with
Satan.

And yet the gambols of electricity are truly extraordinary.

In the month of June, 1873, the electric fluid penetrated into a
butcher's shop, quite calmly followed the iron bars from which the
quarters of meat were hanging. From one of the hooks a whole ox was
suspended. All at once the skinned carcase was galvanized by the
electric current, and during several instants it was seen convulsed by
the most frightful contortions.

Again, on June 28, 1879, a concierge in the Avenue de Clichy was
sweeping his courtyard when the lightning broke at one metre above his
head. The poor man escaped with the fright. The fluid ran up the
leaden pipes and entered a room, where it broke the mirrors and a
clock, injured the ceiling, and got off by breaking the panes in the
window. On the upper storey it got into a lodging occupied by two old
women, where it caused the following damage: one of the women was
holding a bowl of milk, the bottom of the bowl was cracked and the
milk spilled on the floor; some money which was in a wooden bowl
disappeared and could not be found. The clock was stopped at half-past
six, the pendulum unhooked; and a hole made in a glass globe the size
of a five-shilling piece. Finally, a woman in bed on the same landing
saw the bed split in two by the lightning, which disappeared in the
wall. None of these persons were injured.

As a general rule, indeed, when lightning breaks into houses, although
it often does a great deal of harm, it almost always spares the people
who may be there. One is safer there than anywhere else.

Sometimes the walls are pierced or merely hollowed. This perforation
of the walls is one of the most common effects of the meteor on
buildings.

The thickness of the perforated walls is very variable.

At the Castle of Clermont, in Beauvaisis, there was a formidable old
wall, built in the time of the Romans, so tradition has it, which was
ten feet thick, and the cement was as hard as stone, so that it was
almost impossible to break it. "One day," says Nollet, "a flash of
lightning struck it, and instantly a hole, two feet deep and equally
wide, was made in it, the _débris_ being thrown more than fifty feet
away."

On June 17, 1883, at Louvemont (Haute-Marne), the wall of a bakehouse,
fifty-five centimetres wide, was broken in by lightning.

The church at Lugdivan was struck by lightning in 1761. Two furrows
like those made by a plough were to be seen on the wall.

One of the most dreadful acts of which lightning is capable is that of
hurling considerable masses of stone and rock, broken or intact, to
great distances. We have numerous examples of this terrible
phenomenon. Here are a few:--

On August 23, 1853, thunder burst over the belfry of Maison-Ponthieu.
The explosion scattered the slates and beams of the roof, and shot a
stone, measuring thirty-five centimetres, to a distance of twenty
metres. Rough stones, weighing more than forty pounds, were torn up
and thrown almost horizontally as far as an opposite wall thirty feet
away.

At Fuzie-en-Fetlar, in Scotland, towards the end of the eighteenth
century, lightning broke, in about two seconds at most, a mica-schist
rock of one hundred and fifty feet long, by ten broad, and in some
parts four feet thick; this it split into great pieces. One, measuring
twenty-six feet long by ten broad, and four in thickness, fell on the
ground twenty centimetres off. Enormous stones are thrown, at times,
in different directions.

In 1762 lightning struck the belfry of Breag Church in Cornwall, broke
the stone pinnacle of the edifice, and threw one of the stones,
weighing at least a hundred-weight and a half, on the roof of the
apsis, in a southerly direction, fifty-five metres away.

In a northerly direction another huge stone was found at 365 metres or
so from the belfry; and a third, still larger, to the south-east of
the church.

In certain cases the lightning unites a fantastic skill with this
excessive brutality. For instance, a wall has been removed intact
without being broken in any part. Here is a record of one such
extraordinary occurrence:--

On August 6, 1809, at Swinton, near Manchester, during a deluge of
rain, the lightning all at once filled a brick building, in which coal
was stored, full of pestilential, sulphureous vapour. Above it was a
cistern half full. Suddenly the edifice, the walls of which measured
thirty centimetres in thickness, were torn out of the ground, the
foundations being sixty centimetres deep, and was transported in an
upright position to a distance of ten metres.

The weight of this mass, so oddly and so rapidly moved by lightning,
was estimated at ten thousand kilograms.

In many cases, on the contrary, the subtle fluid has pulverized a
hard stone on the spot and reduced it to powder.

Tiles and slates are very often torn off the roofs: the lightning
makes them fly through the air. Sometimes it is content to perforate
them with a multitude of little holes.

As for chimneys, they are generally very ill-treated by the meteor.
The blows of which they are victims are to be accounted for easily,
for they offer perfect powers of conducting to the fulminant matter,
firstly, because of their prominence on the summit of the building,
especially when they are surmounted by a vane. Again, the flue is
often in cast-iron, and if it is bricked it is supported by bars of
iron. The surface of the interior is covered with a layer of soot, an
excellent conductor, and a stove-pipe often opens into it. Then, too,
the hearth and its surroundings are more or less made of metal.
Finally, the column of smoke and of hot, damp air rising into the air,
shows the lightning the way.

The latter often accepts this invitation, and very frequently gets
into a house by the chimney, where everything seems ready for its
reception.

Rafters and doors are sometimes bored through with one or two holes by
the spark, and split or furrowed more or less deeply. A curious fact
is that it is rare to find the slightest trace of combustion round
them.

In the month of August, 1887, lightning struck the belfry of the
church at Abrest (Allier), carrying off part of the roof.

It destroyed the walls of the porch, and in both sides of the swing
doors bored two holes, each as big as a pigeon's egg, and as
symmetrically as if they had been made by the hand of man.

The cleavage of beams is amongst the most extraordinary injuries to be
observed on woodwork. Lightning works with wrought wood just as it
does when the tree is in full sap: it reduces it to rags, and follows
the direction of the fibres.

With what crimes lightning is charged! When it is a question of
robbing a house, it spares nothing in its way.

The window-panes fly in pieces, and sometimes are thrown a long way
off. Often they are melted and disappear totally.

In July, 1783, at Campo Sampiero Castello (Padua), lightning struck a
building full of hay; the windows had glass in them, and the panes
were melted _without the hay catching fire_!

A still more astonishing phenomenon is that of the total disappearance
of the glass panes, observed at the Castle of Upsal, on August 24,
1760. Lightning visited this edifice and then took flight, carrying
off sixteen panes out of a window. Not the smallest fragment of them
was ever found.

Perhaps, as often happens, terrific heat was generated, and the glass
evaporated.

If we follow the track of lightning through rooms, very singular
effects may be seen on the furniture. Chests of drawers and wardrobes
are gutted, and the contents pulled out and strewn about the room. In
the middle of August, 1887, a house at Francines, near Limoges, was
struck by lightning. It fell in a room where the master of the house
was in bed. He felt a terrific shock, and saw his eiderdown pierced
through and through by the perfidious fluid, and a chest of drawers
with all its contents broken. Continuing on its way, the lightning
demolished the door and entered another room.

A man who was asleep in it was killed. His wife by his side and his
little girl felt nothing, but _a pillow on which one of them had her
head was thrown to a distance_. Finally, the meteor went through the
floor, broke a large clock on the ground floor, setting fire to
everything on its way.

On June 1, 1903, a fulminant ray fell on the church of
Cussy-la-Colonne (Côte d'Or). To start, it turned the clock tower
upside down, broke a clock, then opened a cupboard in the sacristy in
which there were various articles, and broke them all.

In April, 1886, lightning did great damage in the church at Montredon
(Tarn). It demolished the steeple to an extent of three metres,
several bells, and carried the enormous iron bar which supported them
a long way off. The roof of the church was burst in and the tiles were
pulverized in several places by the falling masonry. In the interior a
bench was broken, an image of Christ reduced to powder, and a metal
image of St. Peter twisted.

We may remark, by the way, that churches are very often struck by
lightning, doubtless owing to the height of the steeple above the
edifice.

We have innumerable notes about ruined steeples, turrets knocked off,
the plundering of priestly objects. Sculptures and pictures adorning
the sanctuary are often destroyed, and the altar itself shattered.
Cases of priests struck while officiating are not uncommon. As for the
faithful killed while at church, they may be counted by the hundred.

Without wishing to call lightning a miscreant or an infidel, one is
obliged to confess it fails in respect for holy places.

However, the quips and cranks of lightning observed in dwellings are
no less varied and curious.

Here are some remarkable accounts:--

One night during a terrible thunderstorm, lightning came down the
chimney of a room where two people were asleep. The husband awoke with
a start and, believing the house to be on fire, groped his way to the
mantelpiece to get a candle, but was stopped by a heap of rubbish.
Everything, in fact, of which the chimney had once consisted was
heaped up in the middle of the room. The mantelshelf, violently torn
off, had been partly melted, the clock had had the door of the case
pulled off, and all the window-panes were broken. On the lower storey,
another clock was similarly demolished, the floor was torn up and the
tiles thrown with such force against the ceiling that there were
splinters sticking all over it.

In the month of April, 1866, at Bure (Luxembourg), the thunder, which
had been rumbling for some time, suddenly crashed down all at once
about midnight with the most appalling violence, so that the ground
seemed to tremble and the houses rock on their foundations.

All the inhabitants, aroused in terror; instinctively several of them
sprang out of bed, thinking that their dwellings must be annihilated.
Every one had the presentiment of disaster, which was only too real:
the fluid had just struck the house of a poor workman, and left a
scene of frightful destruction behind it.

The roof had been carried off, the chimney destroyed, the windows
reduced, so to speak, to atoms, the principal door smashed and hurled
to a distance; of the furniture there was nothing left but shapeless
wreckage. But what was most extraordinary is, that this catastrophe
only cost the life of one person, while all that were in the house
might well have been killed.

Three children, sleeping in an upper storey, found themselves thrown
outside the house without knowing how they got there, but _safe and
sound_, though the bed was broken to pieces. The father and mother
were asleep on the ground floor, with two little children, one of whom
was at the breast. This latter was flung out of his cradle and thrown
against the wall, without being hurt.

At this moment the mother sprang out of bed to succour those dear to
her, but while the poor woman was in the act of lighting a candle, the
lightning struck her lifeless on the floor. The husband, who was in
the bed with another child, only felt a severe shaking. The lightning,
having accomplished its work of destruction, finally broke an opening
in the lower part of the wall, went into the stable adjoining the
house, and there killed the only cow that was in it.

In the month of August, 1868, at Liége, Rue du Calvaire, at the point
where the mountain of St. Laurent is highest, lightning first of all
struck two earthenware chimney-pots which were higher than the roofs.
One of these pots was thrown to the ground and broken, the other
disappeared. Then the electric spark ripped off a great part of the
roof. All the tiles were scattered round the house. A young servant
slept in a garret under the roof; the lightning penetrated into the
garret through a little hole in the wall just above the head of the
maid's bed; the latter was flung into the middle of the room without
the slightest bruise, though the wood of the bed was bored through in
two places.

From there, the spark going through the wall again, went down to the
ground floor, following the gutter pipe, which it broke. It re-entered
the house by making a little hole in the wall, pulled off the plaster
which was round two nails holding up a mirror, broke part of the
frame; again left the room, entered a little room adjoining where six
people were sleeping--the father, the mother, and four young children;
pierced the wall to enter a locksmith's, scattered all the tools, tore
out a drawer, broke it into a thousand pieces, and threw the contents
on the floor, broke all the panes of glass; again went through the
wall, went to a hutch with a rabbit in it, killed the animal, and at
last went into the garden, where it dug a double trench several feet
long.

The house was occupied by two families of ten persons, none of whom
were struck. Terrified by the report they rose instantly; the smell of
smoke filling all the rooms told them of the danger they had just
escaped.

On another occasion one sees the woodwork of the chimney burnt, as
well as a press, a looking-glass, and a clock badly injured by the
lightning; which before retiring, and by way of being a good joke,
turns a felt hat upside down, and unscrews the andirons.

Examples of this kind are very numerous. We constantly speak of the
caprices of the lightning, but what name could one give to anything so
burlesque or incomprehensible as the following:--

In the month of July, 1896, lightning fell in the village of Boulens,
on a cottage almost covered with thatch. Entering through the chimney,
which it destroyed, it first threw down a rack, pulling out the hinge
which held it up, and making in the place of the said hinge a hole
right through the wall. Afterwards it lifted a pot and the lid from
the hearth over to the middle of the floor, tearing up some tiles as
it went. It broke the latch of the hall door, as well as the key which
was in the lock; this latter was found afterwards in a wooden shoe
which was under the sideboard. Two canes that were beside the
mantelpiece, were laid on the said mantelpiece as if placed there by
hand.

A meat chopper and a copper basin used for ladling water out of a
pail, and attached to either end of the stove, were likewise thrown
into the middle of the room. But the oddest part was that these two
articles were fastened together, the twine which served to hang up the
chopper being rolled round the handle of the basin. Finally, the
flash divided, and zigzagged off, one part carrying off a piece of the
oak jamb of the hall door, the other part piercing a hole above the
stove in a mud wall. Through this it threw fragments of laths and
mortar into a window eleven metres off, near which two people were
sleeping.

This little dance, in which so many and various articles took part,
does not lack piquancy!

This is how lightning joins in the National Fête of France!

On July 14, 1884, in the village of Tourettes (Vaucluse), lightning
struck a house, carrying off a corner of the roof. It knocked off the
lower part of the roof, and broke through a wall at least fifty
centimetres thick.

In a press built half into the wall, and in which there were about
fifteen bottles containing various kinds of liqueur, only one bottle
of spirits was broken, and this was done in such a manner that no
trace could ever be found either of the glass or the liquid.

From thence it sprang to the pictures hanging above the head of a
little girl of five, who was sound asleep. Three pictures were torn
from their frames, engravings and mirrors were ground to powder, but
the child was not hurt. Then the electric current made an opening in
the ceiling, which was about forty-five centimetres thick, broke a
great many tiles as it left the house, but soon returned by way of
the chimney, three parts of which it demolished. Then it explored the
kitchen on the ground floor, where there were three men by a fire.
One, standing up, was thrown violently against the opposite wall;
another was hurled against the door; the third, seated, was raised
from his chair to a height of at least fifty centimetres, and then
dropped. To crown all, the spark tore away half the butt-end of a gun,
and carried it into the next room, where there were eleven people who
got off with nothing worse than the fright. Then going up the chimney,
it exploded at a height of 1·50 metre, throwing bits of plaster and of
the pothanger in all directions.

What frantic and almost childlike fury!

Yet somewhere else the very brother of this ray may caress the little
head of a sleeping child, and not do it the slightest harm; may scoop
a hole in the little cot, and then depart quietly without giving any
further cause for talk. Or this same lightning, terrible and
ungovernable at times, will snatch something out of a person's hand
with so much dexterity, one might almost say delicacy, that one would
hardly dare to reproach him with his lack of ceremony.

At Perpignan on August 31, 1895, lightning fell on the mountains of
Nyer, near Olette. Twenty-five out of a flock of sheep were struck.
The shepherd was enveloped by a flash, yet escaped, but the knife he
was holding in his hand disappeared--and likewise his dog.

Another time it fell on a house at Beaumont (Puy-de-Dôme), flashed
through every part of it, blew up the stone staircase, and did
considerable damage. It grazed a woman who was sitting with a cup in
her hand, but she was not hurt, though the cup was rudely torn out of
her hands.

In July, 1886, a labourer was in the act of mowing, when lightning
coming on unawares, stole his scythe and threw it 10 metres away. The
man was not in the least hurt.

The following example is truly amazing from this point of view.

A woman was busy milking a cow, when suddenly she saw a tongue of fire
shoot into the stable and round it, pass between a cow and the wall at
a place where there was not more than 30 or 35 centimetres of space,
and finally go out of the door without leaving any marks, or hurting
any living thing.

Very often lightning contents itself with making a frightful hubbub,
and breaking any china or glass it may come across.

In July, 1886, thunder burst over a house at Langres. It was at
breakfast-time. The fluid came down the chimney, which it swept
thoroughly, came near the table, ran between the legs of an astounded
guest, and then knocked a hole as big as a shilling in the neck of a
bottle which was being filled at the pump. Then it took itself off to
the courtyard, which it swept clean, and disappeared without hurting
any of the witnesses of this strange phenomenon.

On August 3, 1898, two women were in the dining-room of their house at
Confolens, when lightning broke a pane of glass in the window, and
passing within a few metres of them, went through the kitchen, and
disappeared through the wall, after having broken several cooking
utensils and the mantelpiece into atoms.

At Port-de-Bouc, on August 21, 1900, lightning struck the custom
house, went into the room of one of the officials, and cut clean in
two a china vase, which was on the mantelpiece, without separating the
pieces.

Several days later, on August 26, the mysterious fluid came to disturb
the peaceful repast of two honest labourers. Having taken refuge from
the storm in a hut, they had set out their provisions for breakfast.
All at once the thunderstorm burst into the humble dining-room,
snatched up the bread, cheese, etc., overturned the bottles and other
articles, covered everything with straw, as if by a violent gust of
wind. The labourers felt nothing but stupefaction.

Was not it a veritable farce?

In another place it bursts open a cupboard, throwing the door away,
and damaging the crockery in the most systematic fashion: it breaks
the first plate, leaves the second intact, cracks the next, spares the
fourth, and so on to the bottom of the pile. Then its task finished,
it becomes quite diminutive, like some little gnome out of a fairy
story, and flees through the keyhole, but without making the key
spring out of the lock.

On August 19, 1866, at Chaumont, lightning, having played havoc in a
house in various ways, espied a pile of plates in a cupboard, china
and earthenware plates being mixed, it broke all the china ones,
leaving the others untouched.

Why this preference? The lightning does not explain. It is for us to
find out.

On May 31, 1903, at Tillieu-sous-Aire (Eure), during a thunderstorm, a
number of china plates were filled with a kind of sticky water. The
earthenware plates beside them were not even wet. I received a little
flask of this water sent me by the parish priest, but analysis
revealed nothing unusual.

The following case gives a formal denial to the ancient prejudice
which attributes a cabalistic influence to the number thirteen.

There were thirteen people in the dining-room of a house at Langonar
while the thunder rumbled outside. Suddenly a flash of lightning
struck a plate in the middle of the table, threw dishes, glasses,
plates, knives, and forks in all directions--in a word, cleared the
table, not forgetting the tablecloth.

None of the thirteen guests were touched.

It sometimes happens, indeed, that glasses or bottles are altogether
or partly melted. Boyle gives a very curious instance of the kind.

Two large drinking glasses were side by side on a table. They were
exactly alike. Lightning seemed to pass between them, yet neither was
broken; one was slightly distorted, however, and the other so much
bent by an instantaneous softening that it could hardly stand.

When firearms are struck by lightning, their injuries are often of the
most varied kind. Sometimes the wood, particularly of the butt-end, is
split, or broken to pieces, the metal parts torn out, or thrown right
away.

On July 27, 1721, the meteor struck a sentry-box at Fort Nicolai,
Breslau, and pierced the top to get at the sentry and his gun. The
barrel was blackened; the butt-end broken and thrown to a distance.
The shot had been discharged and pierced the roof of the sentry-box.

The man got off with a few scratches.

However, firearms when carried by men appear to attract the lightning.
Soldiers are often enough struck when in the exercise of their
calling, when they are carrying arms.

But, curiously enough, many cases are known in which lightning has
struck a loaded gun, melting the bullet and part of the barrel,
without setting fire to the powder.

Thus, at Prefling, lightning penetrated the room of a gamekeeper, yet
none of the many firearms hanging up went off. The wall was damaged
between each rifle. One was standing in a corner of the room; the wall
was injured on a level with the lower end, and above it a hole was to
be seen in the woodwork.

On June 1, 1761, near Nimburg, lightning burst into the house of a
horse-keeper, where it struck a loaded carbine leaning against a wall
on the ground floor. The muzzle was slightly melted by the spark,
which ran along the barrel to the trigger, and which it soldered
together in parts. There were five bullets melted and soldered
together in the magazine and the wads much scorched. However,
incredible as it may seem, there was no explosion.

In another case the lightning went the whole length of a rifle, both
inside and outside, leaving a direct line of fusion, and yet,
incredible though it may seem, no shot was fired though the fusion
reached the powder.

These phenomena appear quite extraordinary, and altogether
incompatible with the usual theory of the combustibleness of
gunpowder. To what cause can the invulnerability of the explosive
matter be due?

Doubtless to the quickness of the lightning, which does not leave the
powder time enough to ignite.

Powder magazines are frequently struck by lightning, and this subject
is one of very great interest; they are not always blown up, in spite
of the vast quantities of explosive materials which they contain.

Here are some examples which go to prove this statement:--

On November 5, 1755, lightning fell near Rouen on the Maromme powder
magazine, and split one of the beams of the roof. Two barrels of
powder were reduced to atoms without exploding. The magazine contained
eight hundred of these barrels.

Can it be that man's thunder can repulse that of Jupiter?

Not always, as numerous examples prove the contrary. The following
observations are extracted from a collection of similar facts:--

Lightning struck the tower of St. Nazaire, Brecia, on August 18, 1769.
It stood above an underground magazine containing a million
kilogrammes of powder belonging to the Republic of Venice. The whole
edifice was blown up, the stones falling in showers. Part of the town
was thrown down; three thousand people perishing.

At four o'clock in the afternoon of October 6, 1856, lightning
penetrated the vaults of the church of St Jean, at Rhodes, setting
fire to an enormous quantity of powder. Four or five thousand people
lost their lives in the catastrophe.

The power of lightning is immeasurable. Well, it sometimes enjoys
itself after the following manner:--

In 1899 it lit a candle which had just been put out. The person who
held it was not struck, but the shock sent him to sleep for four days;
then he awoke, only to go mad, and then slept for seven consecutive
days.

At Harbourg it put out all the lights at a ball; the room was plunged
in darkness, and filled with thick and fetid vapour.

Many a time, too, has a fire, burning brightly in a grate, been
suddenly extinguished by lightning; and the same thing has happened
with pottery and tile-making furnaces. As a rule, it is extremely
difficult to re-light candles or fires thus extinguished. In some
instances it takes on itself to light the gas.

On August 3, 1876, near the Observatory in Paris, Rue Leclerc, towards
the corner of the Boulevard Saint Jacques, a gas jet was lit by
lightning. The latter was twenty centimetres from a long gutter, and
was in the gap, so to speak, of an electric circuit formed by it and
the damp wall communicating with the ground. A violent explosion took
place at the moment the gas caught alight, the gas meter, on the wall
two metres above it, was dislodged, when a second explosion was heard.
The thunderclap was truly terrific, and immediately followed the
lightning flash. The chronometer in the meteorological bureau in the
Observatory was stopped suddenly. The keeper of the square of the
Luxembourg saw a ball of red fire explode with great violence, and
scatter in all directions. The plate belonging to the Pères was,
according to M. de Fonvielle, broken to a thousand pieces, and the
outer part of an iron bar was volatilized. There were no deaths or
injuries to record, although several people were thrown down by the
shock.

Sometimes great disasters are indirectly caused by lightning. Thus in
July, 1903, it set fire to an old house at Muda, Paluzzo. Under other
circumstances, the accident might have been insignificant. But, fanned
by a violent wind, the flames increased, and, approaching nearer and
nearer, burned a hundred houses, or in other words, the whole village.

A similar catastrophe took place at the village of Ochres, in
Dauphine, on August 27, 1900. Lightning set fire to twenty thatched
cottages, which, out of thirty-two composing the village, were in
ashes within less than an hour. Three persons were burnt alive, and
four others seriously injured.

On August 25, 1881, lightning struck the village of Saint Innocent, at
three o'clock in the morning. Seven houses were totally burnt, and
three women perished in the flames.

A fire caused by lightning burst out on June 24, 1872, at Perrigny,
near Pontailler (Côte d'Or). Seventeen houses were burnt, and
seventy-eight people found themselves homeless. Sometimes these
disasters attain terrifying proportions.

During an awful thunderstorm, the electric spark set fire to eighteen
parishes in Belgium; ruin spread over an area of 160 kilometres.

But could anything be more dreadful than the fate of certain ships
that have been struck by lightning?

Here is the case of one which was literally cut in two.

On August 3, 1862, the ship _Moses_, on her passage from Ibraila to
Queenstown, was overtaken in sight of Malta by a violent thunderstorm.
Towards midnight lightning struck the mainmast, and then downwards
along it to the hold, cutting the vessel in two. She filled
immediately. Crew and passengers were lost. Captain Pearson was on the
bridge, and had just time to catch a floating spar, which supported
him during seventeen hours. The ship sank in three minutes.

At the commencement of last century, the ship _Royal Charlotte_ being
in Diamond Harbour, on the Hoogley, was struck by lightning and blown
into a thousand pieces, through the explosion of her powder magazine.
The report was heard a great distance off, and the shock was felt for
miles around.

The form and position of the masts exposes them particularly to the
attacks of the dread meteor. Several examples are known of sailors
being struck by the electric current while aloft in the rigging, and
even being thrown from there into the sea.

On August 26, 1900, the steamer _Numidie_, sailing from Bone, was
struck by lightning. The fluid fell on the mizzen-mast, and went down
the standing jib, to which the second officer was clinging. The
unfortunate man had had both his hands paralyzed and fallen; but if he
had fallen on the outside of the draille, death would have been
inevitable.

The _Rodney_ was under weigh before Syracuse when it was struck. This
was on December 7, 1838. The top-gallant-mast went first; it weighed
eight hundred pounds, and such was the violence of the stroke that it
was instantly reduced to shavings, which hung the whole length of the
vessel, like rubbish in a carpenter's shop. The topmast was very much
damaged and shattered here and there. As for the mainmast, with its
ironwork weighing more than a ton, it was wrecked for a length of some
seventeen metres.

At times the masts are split from top to bottom, broken or cut
transversely in fragments, and flung to a distance. Sometimes they
are planed, like the beams and trees of which we have already spoken.

The _Blake_ was struck by lightning in 1812. The top-gallant-mast was
in green pine, which was split into long fibres in every direction,
like branches of a tree.

It is not unusual for lightning to creep into the heart of a mast and
do it all kinds of injuries, without in any way hurting the outside;
in a word, there may be single or double furrows, longitudinal or
zigzag, sometimes curved, and of varying depth. Sometimes also, the
electric current, far more powerful than the blast of the wind, seizes
the rigging and carries it off. This phenomenon was observed on the
_Clenker_, December 31, 1828; the topmast and sails were torn off and
thrown into the water. Neither are the sails spared by the terrible
meteor; they are torn, riddled with holes, or set on fire. But as a
rule the yards are spared.

One of the most frightful effects of thunder on ships is fire, which
it drives from one part of the vessel to another. Under ordinary
circumstances it is usually local, and easily extinguished; but when
it seizes on various parts of the ship at once, as when struck by
lightning, then destruction becomes inevitable.

In 1793 the _King George_ from Bombay was sailing up the river at
Canton, when an electric spark, followed by a violent clap of thunder,
grazed the mizzen-mast, and disappeared in the hold, after killing
seven men. Seven hours later it was discovered with consternation that
the hold, full of an inflammable cargo, was on fire. It spread rapidly
over the whole ship, which it burned to the water's edge.

The ship _Bayfield_ from Liverpool was struck by lightning November
25, 1845. Instantly the deck was seen covered with globes of fire and
large sparks, which set fire to the vessel. As it threatened the
powder-magazine, the captain decided to abandon the ship. A rush was
made for the boats, but as only thirty pounds of bread could be saved,
many perished of hunger and thirst.

Often, indeed, the explosion of the powder-magazine makes the
catastrophe even more terrible. Thus, in 1798, the English vessel the
_Resistance_, was blown up in the Straits of Malacca. Only two or
three of the crew were saved.

But lightning plays more tricks with the compass than with anything
else when it visits a ship. The vibrating, quivering, magnetic needle
is often paralyzed by the electric current; sometimes its poles are
reversed, or the points, disturbed by the passage of the spark,
deviate, and no longer responding to the magnetic pole, mislead and
move hither and thither.

Sometimes they even lose all their magnetic properties.

These changes in the compass often lead to disastrous consequences.
Many cases are known of ships being steered to destruction through the
deviation of the compass. Arago tells of a Genoese ship which, about
the year 1808, sailing for Marseilles, was struck a little way off
Algiers. The needles of the compasses all made half a revolution,
although the instruments did not appear to be injured, and the vessel
was wrecked on the coast when the pilot believed he could round the
cape to the north. This may account for the total disappearance of
certain ships.

Some ships, like certain individuals and certain trees, appear in
particular to attract the electric fluid. We have many records of
vessels struck several times in the course of a single electric storm.
Here are a few:--

On August 1, 1750, the _Malacca_ was struck repeatedly.

In 1848, the _Competitor_ was struck twice within an hour.

At the beginning of December, 1770, between Mahon and Malta, the ship
of a Russian admiral was struck three times in a single night.

On January 5, 1830, in the Straits of Corfu, the _Madagascar_ received
five destructive discharges in two hours.

We could add many others to this list. But enough. And yet we have
not said the last word on the subject. We have to discuss the
interchange of sympathetic currents, and those which are the reverse,
taking place between the electricity of the skies and that of the
telegraph.

Lightning often comes incognito to visit the earth's surface, or even
the depths of the ocean. These little excursions to our terrestrial
dominions usually pass unperceived; however, in certain cases the
telegraph wires commit the indiscretion of revealing them.

On the other hand, we know that the wires entrusted with carrying our
thoughts round the world, are almost inconceivably sensitive. Without
being conscious of the fact, they are in correspondence with the sun,
149 millions of kilometres away, and any agitation on the surface of
this luminary may cause them indescribable agitation, as we witnessed
at the close of the year 1903.

During the formidable magnetic tempest of the 31st October,
telegraphic and telephonic communication were interrupted in many
parts of the world. In fact, the phenomenon was observed all over the
surface of the globe. From nine o'clock in the morning, till four in
the afternoon, the old world and the new were strangers to one
another. Not a word nor a thought crossed the ocean; the submarine
cables were paralyzed on account of solar disturbances. In France,
communication between the principal towns and the frontiers was
interrupted. During this time the sun was in a condition of violent
agitation, and its surface vibrated with intense heat. In such times
the subtle fluid profits by the confusion to glide noiselessly along
the paths which are open to it. But he does not always wait for these
favourable opportunities.

Let a thunder-cloud pass over the telegraph wires, either noiselessly
or hurling petards in all directions, the line will be affected. The
fluid imprisoned in the sky will act by induction on the electricity
of the wires which will result in the vibration of the latter,
accompanied sometimes by a flash of lightning. These phenomena may
cause grave accidents to the telegraph clerks, unless they are on
their guard against the treachery of the lightning. These mute
discharges happen frequently, but the spark strikes the telegraph
wires often, too, as well as the apparatus in the office. All sorts of
accidents result from these repeated attacks.

We know, for instance, how the birds fall victims to the lightning
when they alight on the telegraph wires after a thunderstorm; they are
often found dead hanging by their claws.

But the fluid acts on man also, through the medium of the wires.

Thus, on April 13, 1863, a telegraph clerk was engaged with several
other employees repairing some telegraph wires in the station at
Pontarlier, when all at once they felt, at the knee-joints more
particularly, a violent shock which made them bend their legs as if
they had been struck with a stick; one of them was even thrown down.
No doubt the fluid reached the wires, which in those remote parts was
in charge of the clerks.

On September 8, 1848, during a violent thunderstorm, two telegraph
poles were thrown down at Zara in Dalmatia. Two hours later, as they
were being set up again, a couple of artillerymen, having seized the
wire, felt slight electric shocks, then suddenly found themselves flat
on the ground. Both had their hands burnt; one indeed, gave no sign of
life; the other, in trying to raise himself up, fell back as soon as
his arm came in contact with that of one of his comrades, who ran to
his assistance on hearing him cry for help. The latter thrown down in
turn, felt his nerves tingle, and giddiness seize him, with singing in
his ears. When his arm was uncovered, there was a superficial burn
just on the spot where he had been touched.

On May 9, 1867, lightning fell on the road from Bastogne to Houffalize
(Luxembourg), attracted by the telegraph wire, which it destroyed for
about a kilometre. At a certain part, and over a length of about
twenty metres, the wire was cut in small pieces, three or four
centimetres long, which were scattered over the ground, and were as
black and as fragile as charcoal. The poles which supported them, and
several poplars planted on the same side of the road, were more or
less damaged.

It has been observed that trees planted on the same side as a
telegraph line were sometimes blasted on a level with the wires. It is
the same with houses near the copper threads along which human
thoughts take wing. Thus, at Chateauneuf-Martignes, on August 25,
1900, lightning destroyed the telegraph poles on the outskirts of the
railway-station. A severe shock, like an electrical discharge, was
felt at the same moment by two people who were in bed, not far from
where the wire was fixed in the wall of the house, which was a very
low one. The same phenomenon had been felt there already.

In the railway-stations, as well as in the telegraph and telephone
offices, curious results of the spark passing at a certain distance,
or even in the immediate neighbourhood, are sometimes observed.

On May 17, 1852, towards five o'clock, the sky looking overcast, the
station-master at Havre warned his colleague at Beuzeville that it
would be well to put his apparatus in connection with the ground.
Beuzeville is twenty-five kilometres away from Havre, and at the
former station the weather then did not look at all threatening. But
clouds soon piled up, driven before a violent wind. Suddenly three
awful peals of thunder succeeded each other in quick succession. With
the last, lightning struck a farm about a kilometre from the station,
and at the same moment a globe of fire of a reddish brown, and
apparently about the size of a small bomb-shell, rose as if out of a
clump of trees. It glided through the air like an aerolite, and
leaving behind it a train of light. At a hundred metres or so from the
station, it alighted like a bird on the telegraph wires, then
disappeared with the rapidity of lightning, leaving no trace of its
passage, either on the wires or the station. But at Beuzeville several
interesting phenomena were observed. Firstly, the needles turned
rapidly, with a grating noise like that of a turnspit suddenly running
down, or like a grindstone sharpening iron, which emits sparks. A
great number, indeed, flew out of the apparatus. One of the needles,
that on the Rouen side, went out of order; all the screws on that part
of the instrument were unscrewed, and on the copper dial near the axis
of the needle, there was a hole through which one could pass a grain
of corn.

The instruments at Havre were unaffected. The needle remained as
usual, also the dial, screws, and so on.

One of our correspondents has sent me the following very interesting
communication:--

"On June 26, 1901, having rung up at the central telephone-office at
St. Pierre, Martinique, a harsh noise was heard, which was almost
immediately succeeded by the appearance of a ball of fire, having an
apparent diameter of twenty centimetres, and the brilliancy of an
electric light of twenty candle power. This voluminous globe followed
the telephone wire towards the instrument. Arrived near the receiver,
it burst with a terrific explosion. The witness of this phenomenon
felt a severe shock, and dizziness. Recovered from his stupefaction,
he noted the following facts: the telephone apparatus was completely
burnt, the relay of Morse's installation was slightly damaged. The
electrical tension must have been enormous, for the wire of the
bobbins was, to a great extent, melted."

This latter effect, however, occurs very frequently. Not only does the
lightning melt and break the telegraph wires, but it injures the poles
which support them.

These are sometimes broken, split, thrown down, burst, or splintered,
sometimes into threads or shavings. Poles which have been blasted are
often to be seen alternating with others which are uninjured. Thus, on
the line from Philadelphia to New York, during a great storm, every
alternate pole up to eight was broken or thrown down; the odd numbers
were uninjured. We have mentioned a similar case already.

There are several accounts, too, of lightning in pursuit of trains.

On June 1, 1903, travellers by train from Carhaix to Morlaix, between
Sorignac and Le Cloistre, saw lightning follow the train over a course
of six kilometres, breaking or splitting several telegraph poles.

This feat has been observed more than once. The train is escorted by
lightning flashes which succeed each other almost without cessation,
and the travellers seem to be whirled through an ocean of flame.

Lightning rarely strikes the carriages; only on one occasion did it
actually wreck one, by breaking a wheel. The mutilated coach, however,
continued to hobble along until the injury was discovered.

Generally the fluid is content to wander about the rails, to the great
terror of the passengers who witness this display of rather alarming
magic. It spreads itself over masses of iron, as for instance the
roofs and balconies in Paris, without striking any particular point.

The danger would be greater to a cyclist on a road. In the suburbs of
Brussels, on July 2, 1904, a cyclist named Jean Ollivier, aged
twenty-one years, was riding during a violent storm, when suddenly he
was struck and killed on the spot.

We shall end this description of the whims and caprices of lightning
by a notice of the blasting of a German military balloon. It
happened in June, 1902. The aeronaut, whose car was steered by a
sub-lieutenant, was held captive, and soared at a height of about 500
metres above the fortifications at Lechfeld, near Ingolstadt. All at
once the aerial skiff was touched by an electric spark, caught fire,
and began to descend, slowly at first, then swiftly. The aeronaut had
the good luck to get off with a broken thigh. The five assistants, who
worked the windlass and the telephone, also received shocks
transmitted through the metal wires of the cable. They fell
unconscious, but were quickly restored. This phenomenon, which is
excessively rare, fittingly closes this odd collection of stories,
fantastically illustrated by lightning.

A communication from Berlin also mentions that the captive balloon of
the battalion of aeronauts was struck by lightning on the exercise
ground at Senne. Two under-officers and a private were wounded by the
explosion.



CHAPTER IX

LIGHTNING CONDUCTORS


Until comparatively recent times, as we have seen, all that was known
about thunderstorms was that they occurred pretty well all over the
world, and generally in either spring or summer.

While efforts were being made on our old continent to establish by
long and ingenious dissertations the exact degrees of relationship
between lightning and the sparks given out by machines, in America
practical experiments were being set about towards solving the
problems of electricity.

Franklin it was who hit upon the idea of extracting electricity from
the clouds for the purpose of investigation.

This man of immortal genius, who by his achievements in science, his
noble character, and his devotion to his country, has won the
admiration and gratitude of posterity, was of humble origin.

The son of a soap manufacturer in a small way of business, Benjamin
Franklin was born at Boston in 1706. His parents had intended him to
go in for science. He was successively an apprentice to a candle
manufacturer, a journeyman printer, the head of a big printing firm in
Philadelphia, deputy to Congress, an ambassador, and finally President
of the Assembly of the States of Pennsylvania. His political record
was a great one. No one ever rendered greater services to his country
than the diplomatist who signed the peace of 1783, and insured the
independence of the United States.

It was towards the age of forty that Franklin began his study of
electricity. Here is his own account of the memorable experiments to
which he owed the greater part of his immense fame:--

"In 1746 I met at Boston a certain Dr. Spence, who came from Scotland.
He performed some electrical experiments before me. They were not very
perfect, as he was not a man of great ability; but as the subject was
new to me they surprised me and interested me in an equal degree.
Shortly after my return to Philadelphia, our librarian received as a
gift from Pierre Collinson, a member of the Royal Society of London, a
tube of glass, together with certain written instructions as to the
way in which it should be used for experiments. I seized eagerly on
the chance of reproducing what I had seen done at Boston, and with
practice I acquired a great facility in performing the experiments
indicated to us from England and in devising other ones. I say 'with
practice,' because many people came to my house to witness these
marvels."

After making several discoveries in regard to electricity, Franklin
took it into his head to extract the fluid direct from the clouds. He
had established the fact that a stem of pointed metal, placed at a
great height--on the summit of a building, for instance--served as an
attraction to lightning and guided it into the way prepared for it. He
had been looking eagerly to the erection of a clock-tower which was
being built at this time at Philadelphia; but, tired of waiting and
anxious to carry out experiments which should solve all doubts, he had
recourse to a more expeditious instrument, and one, as events proved,
not less efficacious, for getting into touch with the region of
thunder--a kite such as children play with.

He prepared two sticks in the form of a cross, with a silk
handkerchief stretched upon them, and with a string attached of
suitable length, and set forth on his mission the first time there was
a storm. He was accompanied only by his son. Fearing the ridicule that
is showered upon failure, he did not take any one else into his
confidence. The kite was set flying. A cloud which looked promising
passed without result. Others followed, and the excitement with which
they were awaited can be imagined.

At first there was no spark and no sign of electricity. Presently some
filaments of the string began to move, as though they had been pushed
out, and a slight rustling could be heard. Franklin now touched the
end of the string with his finger, and instantly a spark was given
out, followed quickly by others. Thus for the first time the genius of
man may be said to have come to grips with lightning, and begun to
learn the secret of its existence.

This experiment took place in June, 1752, and made an immense
sensation throughout the world, and was repeated in other countries,
always with the same success.

A French magistrate, named de Romas, making use of Franklin's idea as
soon as it was known in France, took it into his head to use a kite
with raised cross-bars, and in June, 1753, before the full results of
Franklin's experiments were made public, secured still more remarkable
signs of electricity, having inserted a thread of metal throughout the
whole length of the string, which was 260 metres. Later, in 1757, de
Romas repeating his experiments during a storm, secured sparks of a
surprising size. "Imagine before you," he said, "lances of fire nine
or ten feet in length and an inch thick, and making as much noise as
pistol shots. In less than an hour I had certainly thirty lances of
this length, without reckoning a thousand shorter ones of seven feet
and under." Numbers of people, ladies among them, were present at
these experiments. They were not without danger, as may be imagined;
de Romas was once knocked over by an unusually heavy discharge, but
without being seriously hurt.

Franklin was the first to turn his experiments to practical account,
attaching lightning-conductors to public and private buildings for
their protection, and achieving marvellous results; the lightning
being caught by the metallic stem and following it obediently into the
ground.

From this time, lightning-conductors came into almost universal use,
and their value was not long in being generally recognized. Curiously
enough, France, which had been ahead of all other countries in the
study of electricity, was not one of the earliest to go in for
lightning-conductors. There were, indeed, signs of strong hostility to
their introduction. It was held even that they went against the
designs of Providence. In 1766, the Abbé Poncelet, in his work
entitled "La Nature dans la formation du tonnerre et la reproduction
des êtres vivants," in which he sets out to demonstrate that the force
which produces lightning is the same as that which causes the earth to
fructify, makes a strong protest against the construction of
lightning-conductors.

In 1782, nevertheless, at the reiterated request of Le Roi, a member
of the Academie des Sciences, and friend and admirer of Franklin, the
Louvre was endowed with the first lightning-conductor put up on a
public building in France. Soon afterwards they became common.

In 1784 the Academie des Sciences drew up the first set of rules for
the construction of lightning-conductors. It was revised and corrected
in 1823, in accordance with the various improvements that had been
introduced up till then, and it has been further added to in 1854,
1867, and 1903. These instructions point out that the most important
metallic portions of the building should be placed in communication
with the conductor, and this should sink into a well. Conductors that
are not perfectly constructed are a source of danger, instead of being
a protection, for the electric current is apt, instead of running down
into the earth, to make for any kind of metallic substance, and cause
great havoc.

The conductor ought really to communicate with a large body of
water--a body of water of greater extent than the storm cloud from
which the lightning comes. When the flow is insufficient, the water
itself is apt to become electrically charged. It is dangerous to bury
the conductor in merely damp soil; first, because one generally does
not know whether there is enough of this soil; secondly, because one
cannot be sure that the humidity will be sufficient at times of great
drought--the very times when storms are most to be feared. Failing a
river or great pond, the conductor should be put into wells issuing or
having their source in inexhaustible supplies of water deep down in
the soil.

In his table of statistics showing the number of cases in which
lightning has struck either lightning-conductors, or buildings, or
ships furnished with conductors, Quebelet gives a hundred and
sixty-eight cases in which the conductor has been struck, and in only
twenty-seven instances of these (one-sixth of the whole) have the
conductors, from some grave flaw in their construction, failed to
fulfil their office. These results are the best proof possible of the
efficacy of conductors, and the best answer to those who decry them.

The area of protection covered by the conductor is not so great as is
generally supposed. It is limited to a distance about three or four
times the length of the conductor above the roof. Thus a conductor
standing out five yards will protect an area stretching only about
fifteen or twenty yards away. This depends also to some extent upon
the nature of the place and the materials of which the house is
constructed.

Buildings are often struck by lightning because the number of
conductors has been insufficient for the extent of the edifice to be
protected.

To remedy this defect, conductors are made with a number of separate
stems--veritable wire traps in which to catch the lightning. This
system, the invention of a Belgian physicist, M. Melsens, decreases
considerably the risks of destruction, and is much more economical
than the erection of a number of separate conductors.

A conductor of this kind has been installed on the Hotel de Ville at
Brussels, which has been well protected from lightning ever since,
whereas previously this building had been struck by lightning several
times in spite of the single conductors with which it was supplied.
The metallic trellis is in communication with the sewers.

The slaughter-houses of La Villette, the Hôtel Evigné, and other
buildings in Paris, are provided with similar defences.

The Eiffel Tower boasts several such multiplex conductors. It has
often been struck by lightning, but no one who has happened to be up
it at the time has ever suffered any damage therefrom. The lightning
strikes the conductor sometimes from out the actual cloud--curious
photographs have been taken of this. The Eiffel Tower is in itself a
gigantic lightning-conductor.

Portable conductors have been invented from time to time--silk
umbrellas without iron ribs, and clothes of indiarubber and
such-like; but they have all been childish things.

       *       *       *       *       *

Without allowing one's self to get lightning, so to speak, on the
brain, it is well to take certain precautions during a storm.

The first and principal one is not to get under a tree.

The second is to give a wide berth to telegraph posts, so as to avoid
contact with the sparks that may issue from them.

Movements of the air having the effect of preparing an excellent route
for the fluid, it is well not to run in a storm. It is well also not
to ring a bell.

It is well, also, to avoid being in the neighbourhood of animals, in
view of their attraction for lightning.

In houses, doors and windows should be closed in order to avoid
draughts. It is well to keep away from the chimney, too, as well as
from metallic objects.

But lightning always has its caprices. It is this that makes its study
so interesting.



CHAPTER X

PICTURES MADE BY LIGHTNING


In this last chapter I would like to group together a series of
instances of pictures made by lightning, some of them very curious and
attributed, it would seem, to flashes of a special character, which we
may perhaps term Ceraunic Rays, from _Keraunos_, lightning. These
instances are of great variety, and doubtless admit of many different
explanations. Here, then, is a selection worth looking into.

In this case, as in so many others, it is extremely difficult to get
at the exact truth.

Generally speaking, it is from the newspapers that we get the
facts--more or less accurately observed, more or less accurately
recorded. I have made great efforts to inform myself personally as to
the incidents whenever this has been practicable.

The _Petit Marseillais_ of June 18, 1896, published the following:--

"A correspondent writes to us from Pertius, June 17:--

"'In the course of the storm here yesterday, two day-labourers of our
town, Jean Sasier and Joseph Elisson, took refuge in a cabin
constructed of reeds. They were standing at the entrance when they
were struck by lightning and thrown violently to the ground. Elisson,
who was not much hurt, soon recovered his senses and called for help.
People ran up at once and carried the two men to where they live,
where all necessary attention was given to them.

"'Sasier's condition, though serious enough by reason of a burn on his
right side, is not causing anxiety. The curious part of the incident
is the effect the electric fluid has produced upon Elisson. The
lightning cut open one of his boots and tore his trousers; but over
and above this, like a tattooer making use of photography, _it
reproduced admirably_ on the artisan's body a representation of a pine
tree, of a poplar, and of the handle of his watch. It is an undoubted
case of photography through opaque materials; most luckily the
sensitive plate--Elisson's body--merely took the impression and
received no injury.'"

On reading this narrative, I wrote to the Mayor of the Commune of
Pertius to ask him for confirmation of it, and for a photograph, if
possible, of the picture on Elisson's body. By a fortunate
circumstance, the Mayor happened to be the doctor who had attended the
victim. Here is his reply:--

     "M. Joseph Elisson, of Pertius, aged about thirty-eight, was
     struck by lightning on June 17. Called to attend to him at
     about two in the afternoon, I found some superficial burns
     forming a trail, which began near the teat of his left
     breast, at the level of his waistcoat pocket, in which there
     was a watch (which had not stopped), and went down towards
     the navel, then turned boldly to the right towards the iliac
     spine and down the outer side of his right leg as far as the
     ankle, at the level of which his boot, made of strong
     leather, had been split open.

     "To the right, a little outside the vertical line passing the
     teat, there was imprinted in vivid red--the red of the
     burn--a picture of a tree. The foot of it was on a level with
     the edge of the ribs, the top went slightly above the teat.
     This picture was absolutely vertical. Its outlines stood out
     very distinctly from the white skin. It was composed of bold,
     clearly defined lines, about a demimillimetre in width.
     Neither waistcoat nor shirt were burnt or marked in any way
     to correspond with it. Other representations of tree branches
     were reproduced higher up on the breast, but not so
     distinctly in the midst of a uniform redness. Not having by
     me my camera, I made a sketch of the tree, which was
     marvellously distinct, leaving the taking of a photograph
     until next day. Next day, when I returned with my camera, the
     picture was still clearly visible, but it had faded a good
     deal, lost in the colour of the skin, and no longer to be
     reproduced by photography. I regretted bitterly not having
     taken it the day before. I regret this all the more now that
     you have done me the honour of writing to me on the subject,
     and I am glad to be able to send you my sketch of the
     picture, which is correct as to dimensions, and which
     represents what I saw as accurately as I could make it.

                "DR. G. TOURNATOIRE."

Here is a facsimile of the sketch enclosed by the doctor.

[Illustration]

It is somewhat like the shape of a poplar. There is nothing to suggest
that we have here a case of swollen veins, or arteries made
conspicuous by a flow of blood, nor of a tree-like form due to blood
vessels, in which the blood has taken on a more or less marked aspect.
On the other hand, it is certainly not much easier to recognize in it
a photograph of a more or less distant tree. In this state of
uncertainty on the subject, I wrote again to Dr. Tournatoire, and
begged of him to go to the scene of the incident and to make a plan of
the ground, and take a photograph of the view. Here is the doctor's
reply:--

"This plan can be reproduced by a few typographical lines in such a
way as to show clearly how things happened--

[Illustration]

"The square represents the cabin in which the two workmen took refuge.
They were sitting almost opposite each other on the seats marked A and
B. There is a flash of lightning. One of the men is knocked over, and
bears on his right side a picture of the poplar P, which stands one
hundred metres away, and is visible by A through the door O, of which
the width is one metre. Behind this poplar stands a big pine, a branch
of which is also depicted on the man's body. By this same stroke of
lightning the other worker, seated at B, is thrown out of the cabin
three metres by an opening D, about forty centimetres wide. The two
men are alive, and have come out of it with a few days' rest. They saw
nothing, heard nothing, and can remember nothing."

In the photographs taken by Dr. Tournatoire it is not clear which is
the tree, for the poplar, P, does not stand out alone. As the cabin
stands under the shade of a pine tree, one is disposed to ask whether
the lightning did not strike this pine? But judging by the position of
the trees relatively to the man struck, the most likely hypothesis is
that the electric discharge came from the point P towards A, and that
the poplar as well as the adjacent pine formed a sort of screen, and
reproduced their reflection by the agency of some unknown constituent
of these Ceraunic Rays, which enable them to photograph things in this
way through clothes on to the human body.

This assuredly is a more extraordinary effect than those obtained by
the cathodic rays or anti-cathodic rays, of which science seems
equally unable to give any explanation.

Let us proceed with our studies. It is important above all never to
take the newspaper narratives on trust without verification. In the
month of June, 1897, the following appeared in the newspapers:--

"PHOTOGRAPHIC LIGHTNING.--A _chasseur_ of the 15th battalion, in
barracks at Remiremont, was struck by lightning. He was standing upon
a mound not far from a grove of pines, in the midst of ferns. Curious
to relate, on the occasion of recording the fact of the man's being
dead, it was discovered that his body was covered with punctures
imprinted on it by the lightning, and representing the nature and
aspect of the branches and plants all round him at the time when he
was struck."

I wrote at once to the _chef de bataillon_ for a precise confirmation
of this, and received the following reply:--

     "M. le Commandant Joppé, commanding officer of the 15th
     Battalion of Chasseurs, has handed me your letter of June
     14th, and asked me to reply to it.

     "It is the case that a _chasseur_ of the battalion was struck
     by lightning on the afternoon of June 4, but it is quite
     untrue that there was found on his body a photograph of the
     trees adjoining the spot of the accident. The man's clothes
     were not affected in any way, and the only traces left by the
     passage of the lightning, consisted in some slight
     irregularly shaped burns on the upper part of the hollow of
     the right temple of linear formation, save for one circular
     burn measuring from three to four millimetres in diameter,
     and depressing the skin into the shape of a saucer. There was
     no lesion on the whole surface of the body.

                "MAUNY,
                "Surgeon-Major 15th Battalion of Chasseurs."

This reply was covered by a note which ran as follows:--

     "I thought it desirable that the reply to your letter of the
     14th inst. should be made by the surgeon-major of my
     battalion in order that it might be the more scientifically
     accurate and authoritative.

                "JOPPÉ,
                "Chef de bataillon breveté,
                "Commanding Officer of the 15th Battalion of the
                    Chasseurs des Vosges."

Clearly, the student of natural phenomena cannot take too many
precautions. And yet ... an officer of high rank confided to me
recently that "surgeon-majors hardly ever take the trouble to examine
bodies thoroughly," and that it is possible that in this case "the
examination may have been very superficial." If this be a general
rule, there must have been an exception here, as also in the fifth
case, to which we shall be coming just now.

The problem is far from being solved, and we can but seek to study it
as set forth in a number of instances. Here is a third case:--

On Sunday, August 23, 1903, a certain number of riflemen were
practising at the Charbonnières range, near the village of Le Pont, in
the valley of Lalle Joux (Canton de Vaud, Suisse), five targets out of
six were in use. The targets, distant 300 metres from the firing-line,
are placed to the side of a grove of pines. Between stretches an
undulating rock-strewn meadow-land. Only the butts are provided with a
lightning-conductor, and in it are five markers. _There are six
telephone wires along the line of fire_; they come as far as the stand
and go down to within about 50 centimetres of the scorers' seats.
_Each target has its own telephone bell._

The weather was not stormy, though the sky was somewhat overcast.
Firing was going on. At about 3.30 there was a clap of thunder, and
lightning struck the electric wires. In the stand twenty-eight men,
riflemen, scorers, and spectators, are thrown to the ground in every
direction and in every position. Some are quite inert, apparently
dead; others, looking as though they were asphyxiated, give out a
painful rattling noise from their throats. At the bar, to the side of
the stand, no one felt anything--it was not even noticed that there
had been a violent stroke of lightning. A kilometre away the band,
which had been giving a concert in front of the Hotel de la Triute on
the bridge, continued to play. Presently a man reaches them with the
report that twenty of the riflemen have been killed. Consternation
becomes general, and relief parties are organized. Fortunately the
damage done was much less than was supposed.

Let us describe the men actually engaged in firing, and placed in a
line, A, B, C, D, and E, their scorers are behind them.

Let us give our attention, first, to these men and their scorers.
Presently we shall come to the others awaiting their turn, then to
the spectators, and finally to the markers at the targets.

The men were firing, either kneeling or lying.

A remained in position, kneeling "like a statue," unable to move. He
turned right over as soon as he was touched. Killed.

B had _a pine tree depicted on his breast_--upside down, its roots
indicated by some outlines up at the top; the picture was of a
brownish rather than a blueish shade. It was suggested that it
resembled a pine, because of a pine being ten metres away from the
stand, but really it was more like a branch of fern. Killed.

C felt hardly anything apart from a certain heaviness in his limbs
when picking himself up.

D had some slight burns, which were healed within two or three days.

E was holding his rifle with the barrel vertically. He found himself
about 2-1/2 metres from his position on the ground, with a stone in
his hands; his rifle had been bent in two below the trigger.

A's scorer held the pear-shaped handle of the electric bell between
his fingers, his elbows upon the table. Saw nothing, heard nothing.
Felt himself suddenly bent up double, his face buried in the gravel;
lost consciousness while he was being carried away; when he came to
himself again he began to ramble in his speech; his pencil was broken
lengthwise into four pieces. The wire of his bell had been
electrified. By way of wound, he had a picture of a pine branch on his
back; water issued from it as from a blister; there were no traces of
blood. The picture disappeared at the end of two days. For a certain
time the young man had a pain in his loins; he still limps somewhat;
probably what he now suffers from is sciatic lumbago, the result of
partial and temporary paralysis.

B's scorer had only some insignificant burns.

C's scorer only came to himself twenty minutes later as the result of
artificial respiration. At the moment of the lightning he was pressing
the electric button with his thumb in order to give the signal,
"Change the target;" he had a small hole in his thumb. This burn bled
later, and the wound took four weeks to heal. He had also some burns
on his legs.

D's scorer was holding the handle of the bell against his left cheek,
on a level with his eye. The handle, made of wood, burst. The sight of
his left eye is still affected, being very weak--the retina was
probably torn away. The day after the accident, the young man's face
became all inflamed, especially the part round the eyes. These were
quite hidden. This inflammation, of a bluish tint, is due to the
dilation of the small veins or of the capillaries.

Dr. Yersin, who attended several of the victims, attributes this
dilation to a paralysis of the vasomotor nerves, "_which would also
explain the tree-like form of the pictures seen upon the skin_," and
the transudation (?) of water across the small blood-vessels.

E's scorer had time to see the men on his left fall, in a green or
violet light. He had heard a general death-rattle-like chorus,
"Aôôô"--then, before he could make out what was happening, he found
himself driven up against the wall of the stand. He had a wound under
his feet; his thumb torn also, probably in trying to hold himself up
against the wall.

Behind the scorers were a dozen other riflemen and some spectators. To
the left the electric current left intact the rifles standing on the
rack. Quite near this, a man awaiting his turn fell, clinging on to
the neck of one of his comrades, also struck. Later he found his purse
in the middle of the stand.

In the case of several of the spectators, the burns were to be found
in separate sores. One had his hair burnt on one spot of about the
size of a five franc piece; others, who had burns upon their feet and
legs, are under the impression they saw a small blue flame at the tips
of their shoes.

The general feeling was at first merely that of stupefaction. Terror
did not come until afterwards. "Those who did not lose all
consciousness were half stunned." A young boy was noticed jammed up
against the wall, incapable of moving, but bewailing his inability to
get to his father, who lay dead upon the ground. Two men took flight
without throwing aside their guns; another ran as far as the village,
and some hours afterwards he was found asleep in a house "to which
there was nothing to take him." One young spectator, a stranger to the
neighbourhood, was seized with a partial paralysis of the brain; he
could not keep his balance when walking, and when questioned he would
recite the names of stations on a Swiss railway. He is better now.

This event will not be soon forgotten in the Joux valley. But Dr.
Yersin's explanation of the Ceraunic pictures does not seem to me to
be justified.

Here is a fourth instance, given me long ago by one of the most
learned physicists of last century, Hoin, of the Institute.

"I am going to tell you," he wrote to me in July, 1866, "of a stroke
of lightning which was very curious in its effects. It occurred at
midday on June 27, at Bergheim, a village situated to the north of
Logelbach at the foot of the Vosges. It struck two travellers who had
taken refuge under the tree and knocked them over senseless--one of
them was lifted to a height of more than a yard and thrown upon his
back. It was thought they must be dead, but thanks to the attention
given to them at once, they were brought to themselves, and they are
now out of danger. But here is the strange feature of the accident.
Both travellers have on their backs, extending down to their thighs,
_the imprint, as though by photography, of the leaves of a lime tree_;
according to the statement of the Mayor, M. Radat, _the most skilful
draughtsman could not have done it better_."

Here is a fifth instance which I find among my records. The incident
happened at Chambéry, May 29, 1868.

In the course of a violent storm, a soldier of the 47th Regiment was
struck by lightning underneath a chestnut tree. In a memorandum drawn
up on June 18 by a learned doctor of Chambéry, an eyewitness of the
occurrence, the following facts are recorded:--

"The man who was killed had been standing in the centre of a group of
eight soldiers, who had their guns in their hands, without bayonets.
Struck in the region of the heart, he did not succumb for about a
quarter of an hour, after saying a few words. The corpse bore an oval
plate, so to speak, of about 13 to 14 centimetres in length, by 4 to 5
in width, occupying largely the precordial region, and presenting the
parchment-like aspect of a vesicatory that had become rapidly dried
up. The clothes were neither torn nor burnt.

"Two hours after his death an examination of the body resulted in the
discovery of a phenomenon already recorded by several observers--the
reproduction of photo-electric pictures.

"On the right shoulder were three bunches of leaves of a more or less
deep reddish violet hue, reproduced minutely with the most absolute
photographic precision. The first, situated on the lower part of the
inside of the forearm, represented a long branch of leaves like those
of a chestnut tree; the second, which seemed to be formed by two or
three such branches twisted together, was in the middle of the outside
of the arm; and the third, in the middle of the shoulder, larger and
rounder, showed only some leaves and small branches at the top and at
the borders, the centre presenting a red stain diminishing towards the
circumference. The body, when dissected, bore no sign of any interior
lesion."

Here is a sixth instance:--

In June, 1869, a Trappist was struck by lightning at the monastery of
Scourmant, near Chimay in Belgium. It was the afternoon, and the monks
were busy mowing. The storm coming along obliged them to seek shelter.
One of them, who was following the mowing machine worked by two
horses, directed it towards an ironwork enclosure, and knelt down
beside this trellis. There was a terrible thunderclap, the horses
bolted in their fright, and the monk remained with his face to the
ground. The others, who saw him fall, ran up to his assistance, only
to find him dead. The medical attendant of the monastery, sent for at
once, discovered on the body two large and deep burns, identical in
shape, and placed symmetrically to each side of the breast; he pointed
out also to those who were present a white spot under the left armpit,
_presenting a very distinct picture of the trunk of a tree with
branches on it_.

Out of these six cases, five may be taken as fully authenticated.

Dr. Lebigne, Mayor of Nibelle (Loiret), published the following
narrative in the _Moniteur_ of September 7, 1864.

"On Sunday, September 4, 1864, at about 10.30 a.m., three men were
busy gathering pears about 200 metres out of Nibelle, when the pear
tree was struck by lightning, and was distorted from top to bottom in
the form of a screw; the lightning carried away the bark and about a
centimetre of the wood beneath; then quitting the tree, it struck the
head of one of the workmen, who was eating some bread at the time, and
killed him, as well as a dog by his side. The head was burnt behind
from top to bottom and was impregnated with a strong smell of sulphur.

"The two other workmen who were on the tree were thrown to the ground,
and remained for some time senseless. When they came to themselves
they could not move their legs. They were taken to their homes, and it
was found that both had been in contact with the electric fluid. The
astonishing thing about them is, that _one of them had the branches
and leaves of the pear tree clearly imprinted on his breast as though
by daguerreotype_. The terrible photographer had been merciful,
however, for that evening both the men were up again and able to
walk."

The _Comptes rendus_ of the Academie des Sciences for the year 1843
(xvi. p. 1328) records that in July, 1841, in the department of
Indre-et-Loire, a magistrate and a miller's boy were struck by
lightning in the vicinity of a poplar. It was found that both of them
had on their breasts stains exactly like the leaves of a poplar. These
marks, in the case of the magistrate, went away gradually as the blood
began to circulate again. In the case of the boy, who was killed on
the spot, they had faded somewhat by the day after, when decomposition
had begun to set in.

_A propos_ of this case, very similar to those preceding, Arago
recalled the fact that in 1786 Leroy, a member of the Academie des
Sciences, declared that Franklin had several times told him how a man
who was standing at a door during a storm had seen a tree struck by
lightning opposite him, and that a representation of this tree was
found imprinted upon his breast. Arago recalled, too, in this
connection a report made to the old Academy in August 2, 1786, by
Bossuet and Leroy, in which there was question of a man killed by
lightning on May 10, 1585, in the Collegiate School of Riom in
Auvergne; in this case the electric fluid had entered by the heel and
gone out by the head, leaving on the body singular marks, described in
the report. It was thought that the lightning on its way, through
having forced the blood into all the vessels in the skin, must have
made all the ramifications of these vessels sensitive to impressions
from without. Extraordinary though this may appear, they go on to say,
it is not new; Père Beccaria cites a similar case; and Franklin's case
is cited here also as analogous. Besile, the author of the record of
the Riom case, "did not hesitate," he tells us, "to attribute the
effect to an eruption of the blood in the vessels of the skin,
producing a result similar to that of an injection." The statement in
the _Comptes rendus_ is entitled "Strange appearance of Ecchymoses
formed by lightning upon the skin of two persons."

That is just the question. Was there in these pictures nothing but
ecchymoses--infiltrations of the blood into the cellular tissue?
Perhaps that may be so in some cases, but not in all. Photography, the
photo-electric pictures produced in the laboratories of physicists,
Moses's _figures_(?), the Lichtenberg flowers, cathodic rays, Rontgen
rays, radiography-all these things open new horizons for us. And even
if we do not find any explanation satisfactory, we should not be
justified in accepting the first offered to us as being so, if in fact
it be not.

Here are four interesting cases recorded by Poey in his "Rélation
Historique des images photo-electriques de la foudre."

Mme. Morosa, of Lugano, seated near a window during a storm,
experienced a shock from which she is not stated to have suffered any
ill effects; but a flower, which had stood in the route of the
electric current, was found perfectly _drawn_ on her leg, and this
picture lasted the rest of her days.

In August, 1853, a young girl in the United States of America was
standing at a window facing a nut tree at the moment of a dazzling
flash of lightning; a complete picture of the tree was reproduced on
her body.

In September, 1857, a peasant woman of Seine-et-Marne, who was minding
a cow, was struck by lightning under a tree. The cow was killed, and
the woman was thrown on the ground insensible. She was, however, soon
revived. In loosening her clothes to attend to her, the people who
came to her assistance found perfectly reproduced on her breast _a
picture of the cow_.

On August 16, 1860, a mill at Lappion (Aisne), belonging to M.
Carlier, was struck by lightning. On the back of a woman of
forty-four, who was also struck, the lightning left a reproduction (of
a reddish hue) of a tree--_trunk_, _branches_, _foliage_, _and all_.
Her clothes bore no trace of the passage of the lightning.

Unless we are to suppose that all these have been inaccurately
observed, it seems to me that we must admit that there is something
else besides ecchymoses, something else besides the workings of veins
and arteries in these pictures wrought by lightning.

Certain of these tree-like pictures resemble the patterns we get in
photographing electrical discharges upon sensitized plates. Might they
not be produced by this discharge upon the surface of the body--or by
the emission of electricity from the body struck?

The pictures we shall now hear of, to be distinguished from those
already dealt with, are easier to explain, and about their genuineness
there can be no doubt.

In the summer of 1865, a doctor from the neighbourhood of Vienna, Dr.
Derendinger, was returning home by train. On getting out at the
station he found that he had not got his purse on him--some one
probably had stolen it.

This purse was made of tortoise-shell, and had on one side of it a
steel plate marked with the doctor's monogram--two D's intermingled.

Some time after, the doctor was called to attend to a stranger who
had been found lying insensible under a tree, having been struck by
lightning. The first thing that he noticed on examining the man's body
was that on his thigh there was a reproduction, as though by
photography, of his own monogram. His astonishment may be imagined. He
succeeded in reviving the stranger, who was taken to a hospital. The
doctor remarked that in his clothes his lost tortoise-shell purse
would probably be found. So it proved. The individual struck by
lightning was the thief. The electric fluid had been attracted by the
steel plate, and had imprinted the monogram upon the man's body.

In this case we are set thinking of electro-metallurgy, all the more
because there are a number of other instances which certainly belong
to this category. Thus, for instance, on July 25, 1868, at Nantes, a
stranger near the Pont de l'Erdre, on the Quai Flesselles, was
enveloped by a flash of lightning, but proceeded on his way without
experiencing any ill effects. He had on him a purse containing two
pieces of silver in one compartment and a ten-franc piece in gold in
another. On taking out his purse he found that a coating of silver
taken from one of the silver pieces--a franc--had been transferred to
both sides of the ten-franc piece. The franc, slightly thinner,
especially over the moustache of Napoleon III., was in parts slightly
bluish. This transference of the silver on to gold was made through
the skin of the partition of the compartments![1]

Another case. In Gilbert's "Annalen der Physik" (1817) we read that a
flash of lightning struck the tower of a chapel near Dresden and took
the gilt off the framework of the clock and transferred it to the
leaden runs of the window-panes in such a way as to leave no sign of
how these had been gilded.

In these cases the analogy with galvano electro-metallurgy is evident.
But in the earlier cases this was not so; the trees contained no
metallic element. It was not a case of transference. They seem to have
been photographed by the ceraunic rays.

On October 9, 1836, a young man was killed by lightning. The corpse
bore in the middle of the right shoulder six rings of flesh-colour,
which seemed the more distinct in that the rest of the man's own skin
was very dark. These rings, overlapping each other, were of different
sizes, corresponding exactly with those of the gold coins which he had
on him on the right side of his belt, as the public official who
examined his body and all the witnesses were able to testify.

This makes us think of radiography.

A correspondent of Poey, the astronomer, told him that he had known a
Trinidad lady who had been struck by lightning in her youth and on
whose stomach the lightning had imprinted a metallic comb which she
carried in her apron.

In these instances there was some kind of contact of the objects with
the persons struck. Here are others in which the objects reproduced
are further removed, but still of metallic substance and still
reminding us therefore of electro-metallurgy.

In September, 1825, the brigantine _Le Buon-Servo_, at anchor in the
Bay of Armiro, was struck by lightning. A sailor seated at the foot of
the mizzen-mast was killed. On his back was found a light yellow and
black mark, beginning at his neck and going down to his loins, where
there was discovered an exact reproduction, in facsimile, of a
horseshoe nailed to the mast.

The mizzen-mast of another brigantine was struck by lightning in the
roadstead of Zaube. Under the left breast of a sailor who was killed
was found imprinted the number 44, which his mates all declared was
not there before. These two figures, large and well formed, with a
full stop between them, were identical with the same numbers in metal
affixed to the rigging of the ship, and placed between the mast and
the sailor's bunk, in which he was lying asleep when struck.

May it not have been a tattoo-mark in spite of what his companions
declared?

M. José Maria Dau, of Havana, records that in 1838, in the province of
Candaleria, in Cuba, there was found on the right ear and on the right
side of the neck of a young man struck by lightning, the reproduction
of a horseshoe, which had been nailed up at a short distance from him
against a window.

These various records lead us to the reflection: first, that
ceraunography should form a new branch of physics, well meriting
study; secondly, that the facts set forth are sufficiently inverse in
their nature to show us that we have before us several quite distinct
specimens of phenomena.

However, these matters have been a subject for study long before our
day.

A priest, P. Lamy, of the Congregation of Saint Maur, published in
1696 an excellent little work,[2] informed by the most lucid common
sense upon the curious effects of lightning--then a text for the most
superstitious commentaries. Voltaire could not have reasoned the thing
out better. He deals with two very extraordinary cases among others.

The first had for scene the Abbey of Saint Médard, at Soissons, on
April 26, 1676. A flash of lightning struck the tower of the abbey,
went into the clock, penetrated a wall eight feet thick, by a hole
conducting an iron rod _à l'aiguille de cadran_, detached two planks,
four feet high, and threw them to the extreme end of the dormitory,
followed a brass wire stretched along the whole length of the wall,
setting fire to it and spreading it out like a ribbon painted to
represent a furrow of flames. Here is the author's own description:--

"The most surprising effect, and one which has aroused the curiosity
of an immense number of people, is a kind of frieze of all kinds of
colours extending along the wall of the dormitory and just above the
doors.

"The depth of this frieze is about two feet; its length is almost
equal to that of the dormitory; the designs upon it are of flames
darting up and down from a kind of wide band which occupies the centre
of the frieze throughout its length.

"I have had a portion of this frieze copied, so as to give the reader
an idea of it, but it must be admitted that it is difficult to suggest
the variety of _nuances_ in the original. Some people declare that in
the midst of all the colours in the flames, faces of men may be
descried as well as of marmosets and demons; but those who are less
richly endowed with imagination can see nothing of all this."

On p. 274 is a copy of the design by P. Lamy.

At this period, physicists were of the belief that lightning was "an
exhalation of nitre and sulphur," acting something after the fashion
of powder, and able to burn up or throw over everything encountered on
its route. In this girdle traced by the lightning, the author sees a
scattering of all the constituents of the brass wire, transformed into
all kinds of colours due to the dilation of the copper, melted and
vaporized over the width of two feet, the colours, in which yellow
predominates, varying according to the thickness and the inequalities
of the "projection."

[Illustration]

The second case examined into by P. Lamy, was that of what happened in
the church of Sauveur at Lagny, when it was struck by lightning on
July 18, 1689. This is one of the most astounding in the entire
history of the subject. Let us see what our author has to tell us:--

"If we were to look for some excuse for the strangeness and diversity
of the people's sayings and doings in connection with the Lagny case
of lightning, we should assuredly find it in the extraordinary nature
of the case itself.

"For what would naturally be the effect upon minds accustomed to see
mysteries in the most transparently natural events, minds whose
philosophy never goes beyond the senses, when they learn--

"1. That the lightning had not only descended upon the clock-tower of
the church, and carried off the slates from its roof, but had struck
and overthrown nearly fifty persons inside the edifice, and wrought
great havoc on the high altar.

"2. That it knocked over and broke the pedestal on which the figure of
Christ was raised to the level of the altar-screen, though this figure
remained miraculously suspended in the same place--for this is what is
reported.

"3. That it carried off the curtain covering the panels of the altar
and threw it to the ground without breaking or melting any of its
rings, which were made only of copper, and without displacing the rod
above the ring-bolts on which they hung.

"4. That it upset the oil-lamp burning before the high altar.

"5. That it broke into two pieces the stone upon which the priest
consecrates the Host.

"6. That it tore into four pieces the card on which the canon of the
Mass was printed.

"7. That it tore the altar-cloth and the cloth which was over it--both
of them in an extraordinary way, namely, in the form of a cross of St.
Anthony.

"8. That the high altar was seen to be burning.

"9. That it burnt a part of the communion-cloth and of the tabernacle,
upon which it formed several black waves.

"10. Finally that it imprinted upon the altar-cloth the sacred words
of the consecration, beginning with _Qui pridie quam pateretur_, and
going down to _Hæc quotiescumque feceretis in mei memoriam facietis_,
inclusive; only omitting those which are usually set forth in special
characters, namely, _Hoc est Corpus meum_; _et Hic est Sanguis meus_.

"What, I repeat, can you expect unphilosophical minds to make of so
astonishing an affair as this? How account for the choice, the
discernment, and the mysterious preference for some words over others.
Which shall we consider the privileged words--those taken or those
left? What is one to think of the extraordinary way in which the
figure of the Saviour was left hanging? And of that strange imprint of
the cross? How resist all the thousand delusions and uncertainties and
fears the entire thing calls forth?

"I wonder whether the unfortunate Balthasar, when his eyes beheld the
terrible sight of the unknown hand inscribing upon the walls of his
banqueting-room the announcement of his doom, can have been a prey to
a greater variety of fears and tremors than those who witnessed or who
even heard of the effects of the lightning at Lagny. For no doubt was
felt that they were the outcome of supernatural forces--spirits alone
could have worked these marvels; it was a question only whether they
were the work of evil spirits or good. Some believed them to be the
work of good spirits, deducing this from the omission of the words,
_Hoc est Corpus_, etc., which they set down to a spirit of reverence
for the sacred mystery.

"Others believed them to be the work of evil spirits, but here again
there were different theories. Some held that bad spirits had
perpetrated these things out of sheer wickedness, wilfully profaning
the holy objects and suppressing out of contempt, or some other evil
design, the words so essential to the mystery; others held that mere
imps had been at work, actuated more by mischief than sinfulness, and
wishing only to give amusement to themselves and others by the
quaintness of their pranks. I myself do not share any of those
theories."

Lamy's narrative proceeds to an examination of all the effects
recorded, which he explains in the simplest way in the world, without
having to have recourse to any occult causes. He comes, finally, to
the last of all and the most extraordinary.

"Not wishing to put trust in anything but my own eyes, I went to the
church myself, and the effects of the lightning I saw there repaid me
for the trouble.

"I examined carefully the new imprint on the cloth. I found it very
clear and fine, the letters well finished, but the ink a little
indistinct, perhaps I should say faded. As M. le Curé de Saint-Sauveur
(who was kind enough to show me everything) assured me that at the
moment of the lightning the three-leaved card which contains the canon
of the Mass lay between the altar-cloth and the small mat upon the
stone on which the consecration takes place, folded in such a way that
the printed side was next to the altar-cloth, I compared the
characters printed by the lightning with the original lettering, and
found that they corresponded exactly, except that they went from right
to left, backwards, so that they had to be read with the help of a
mirror, or else through the cloth from behind.

"I observed that the words which the lightning had not printed on the
cloth, but had omitted, were done in red letters on the card, and were
no more favoured nor ill-used than certain other marks without any
significance also printed in red upon the card, and leaving no trace
upon the altar-cloth."

The author proceeds to explain the so-called mystery, ascribing it to
the difference between the two inks--the thick black ink and the thin
red ink. He examines also into the other phenomena, explaining them
in the same way, like the sagacious and enlightened observer he was.
It is clear, then, that the study of the phenomena of lightning is no
new thing, and that it has been followed conscientiously for many
centuries.

In the case of the canon of the Mass printed by the lightning at
Lagny, the reproduction was by contact and pressure--it was not a case
of reproducing distant objects as though by photography. Here is
another case hardly less remarkable. The narrative is from the pen of
Isaac Casaubon, in his _Adversaria_:--

"On a summer's day, about 1595, while divine service was in progress
in the Cathedral at Wells, two or three thunderclaps were heard, of so
terrible a nature that the whole congregation threw themselves down on
the ground. Lightning followed at once, but no one was hurt. The
astonishing thing about the affair lies in the fact that crosses were
afterwards found to have been imprinted upon the bodies of some of
those present at the service. The Bishop of Wells assured the Bishop
of Ely that his wife told him she had a cross thus imprinted upon her;
and that on his being incredulous, she had shown it to him, and that
he himself found afterwards that he, too, was thus adorned--on his
arm, if I remember right. Some had it on their breast, some on their
shoulders. It is from the Bishop of Ely I have these facts, which he
tells me are well authenticated."

What shall we say now of the photographing of a landscape on the
inside of the skin of sheep which had been struck by lightning? The
record of this seems well authenticated.

In 1812, near the village of Combe-Hay, four miles from Bath, there
was a wood composed largely of oaks and nut trees. In the middle of it
was a field, about fifty yards long, in which six sheep were struck
dead by lightning. When skinned, there was discovered on them, on the
inside of the skin, a facsimile of part of the adjacent landscape.
These skins were exhibited at Bath.

This record was communicated by James Shaw to the Meteorological
Society of London at its session of March, 1857. Here are his own
words:--

"I may add that the small field and its surrounding wood were familiar
to me and my schoolmates, and that when the skins were shown to us we
at once identified the local scenery so wonderfully represented."

Andrès Poey tells us of these other curious cases:--

In the province of Sibacoa, Cuba, in August, 1823, lightning imprinted
on the trunk of a big tree a picture of a bent nail, which was to be
found, bent in the opposite direction, embedded in one of the upper
branches.

On July 24, 1852, in a plantation at St. Vincent in Cuba, a palm tree
was struck by lightning, and engraved on its dried leaves was a
picture of pine trees which surrounded it at a distance of nearly 400
yards.

Dr. Sestier tells us that after the 1850 meeting of the American
Association, a person was killed by lightning while standing up near a
whitewashed wall, and that his silhouette was fixed upon the wall in a
dark colour.

With such facts before us, we seem bound to believe in the existence
of some kind of especial rays, ceraunic rays, emitted by lightning,
and capable of photographing alike on the skin of human beings,
animals, and plants, more or less distinct pictures of objects far and
near.

Decidedly, we have much to learn in this as well as in all the other
branches of knowledge.
