PREFACE.

This little book is written for three classes of readers--for
horse-owners who may interest themselves in the subject, for farriers
who are open to conviction, and for veterinary students who have to be
examined.

The method pursued has been, to first describe the form and action of
the foot, next the preparation of the foot for shoeing. Then the form
of a shoe is treated of and the details to be observed in making it.
The selection of shoes for varieties of feet or for special kinds of
work follows, and afterwards the fitting and nailing-on are considered.
Other chapters are devoted to "roughing," shoeing defective feet,
accidents, the use of leathers and pads.

Throughout an endeavour has been made to be as simple and clear as
possible in expression, to lay down correct general principles and to
point out the technical details which are essential to good shoeing.
On all these points authorities are not agreed, and I trust those who
differ from me will pardon any too dogmatic expressions of opinion in
these pages.

The illustrations will be of assistance in making clear the text.
Some of these are copied from books, some are drawn from models or
preparations, and some are diagramatic. The books I am indebted to are,
"Anatomy of the Domestic Animals," by Gamgee and Laws; "On the Horse's
Foot," by Bracy Clark; Bouley's "Atlas of the Foot," and Goyau's
"Maréchalerie."

THE ART OF HORSE-SHOEING A MANUAL FOR FARRIERS.

CHAPTER I.

Farriery is the art of shoeing horses, and can only be properly learned
by a long practical experience in the shoeing-forge. If the foot of the
horse were not a living object perhaps the training obtained in the
forge would be all that was necessary for efficient workmanship. As,
however, the hoof is constantly growing it is constantly changing its
form. The duty of a farrier therefore is not merely to fix a shoe upon
the hoof but to reduce the hoof to proper proportions before doing so.
Now as hoof is only the outer covering of a complex and sensitive foot,
damage to the exterior surface may injure the structures within. Injury
does frequently result, and not always from carelessness. Perhaps as
much injury follows careful work, based upon wrong principles, as
slovenly work carried out in perfect ignorance of any principle. The
injury to feet resulting from shoeing may not be apparent at once. It
may be, and often is, of a slow and gradual nature, and not credited to
its true cause until the horse is rendered an incurable cripple.

It seems evident then that to do justice to a horse a farrier should
not only possess manipulative skill, but should have a correct idea
of the structures and functions of the foot, as well as a thorough
knowledge of the form and variations of the hoof.

Few persons appreciate the importance of horse-shoeing, whilst a small
number tell us it is unnecessary. Here and there an enthusiast has the
courage of his convictions and is able, for a time, to exhibit animals
doing work without shoes. In some countries horses are regularly ridden
with no addition to their natural hoof, but in such places the surface
over which the animals travel is grass land. In all civilised countries
where good roads exist shoeing is practised. The gentleman with a fad
who occasionally appears in England with unshod horses at work is an
unconscious impostor. He sets his little experience against the common
sense and universal practice of others. No man of business would pay
for shoeing if he could do without it. The "shoeless" experiment has
been tried over and over again, but always with the same result--a
return to shoeing. In dry weather the hoof becomes hard, and it is
wonderful how much wear it will then stand on the hardest of roads.
In wet weather the hoof becomes soft, and then the friction on hard
roads soon prohibits work without shoes. If work be persisted in, under
such circumstances, the hoof rapidly wears away and lameness results.
Persons trying to prove a pre-conceived theory meet this difficulty
by resting the horse until the horn grows, but business men who keep
horses for work in all weathers can afford no such luxury. Shoeing has
been called "a necessary evil." The phrase is a misuse of words, for
there is no necessary evil about it. Of course it is no more free from
accident than other operations, but its evils are fairly described
as accidents, whilst its benefits are fully apparent. Without shoes
horses at work would be more often lame than with them; without shoes
horses could not do half the work they do with them, and so we need not
further discuss the necessity of shoeing.

The value of horse-shoeing depends upon the manner in which it is done.
Very seldom does the owner of horses appreciate the quality of the
work. As a rule the price charged, or the distance from the forge to
the stable, regulates the choice of a farrier. Not having any pecuniary
interest in the trade, I may say that such matters should not be
allowed to decide between one farrier and another. A bad workman may do
an injury at one shoeing which will cost the owner of the horse more
than would pay ten times over the difference between his charges and
the higher prices of a better man.

Many years ago I knew a firm who changed their farrier and system
of shoeing for a cheaper plan. The cost for shoeing alone fell very
considerably, but the cost of horse-flesh rose in one year more than
£100. The old saw--"that for want of a nail the shoe was lost, for
want of a shoe the horse was lost, and for want of a horse the man
was lost," has been illustrated times without number. Few persons,
however, are aware of the terrible consequences which have more than
once attended neglect in the shoeing of horses. Napoleon's retreat from
Moscow depended for most of its hardships and horrors upon the simple
fact that his horses were not shod properly for travelling on snow and
ice. The horses could not keep their feet, and were unable to drag the
guns and waggons, which had to be abandoned. During the Franco-Prussian
war, Bourbaki's retreat became a confused rout from a similar cause.
In civil life no winter passes without injury and death to hundreds of
horses from the same neglect. These are instances that anyone can see;
but heavy losses due to bad shoeing are constant from other or less
evident evils--from the adoption of wrong methods and the practice of
erroneous theories.

The farrier has not been fairly treated by the public. His practical
knowledge has been ignored, he has been instructed by amateurs in all
sorts of theories, and coerced into carrying out practices for the
untoward results of which he has been blamed. The natural consequence
of all this has been that the art of farriery degenerated, and the
farrier was forced into a position destructive to the self-respect of
any craftsman. In no other trade do persons entirely ignorant of the
business presume to direct and dictate as to how the work should be
done. No one presumes to instruct the watch-maker or bell-hanger as to
the details of his craft, but the farrier has been compelled to take
his instructions from all sorts and conditions of men.

Only in recent years has the man who shoes horses been allowed to know
something of his calling. Various causes have acted in putting an end
to the state of discord, and the trade is now entering upon a brighter
time. The Worshipful Company of Farriers--one of those ancient City
Guilds which had survived their original vocation and usefulness--has
wakened up, and is striving to resume its proper function as the head
and director of the trade over which it ought to preside. Agricultural
Societies have also taken the matter up, and fostered a healthy
emulation amongst farriers by instituting practical competitions at
their shows. Veterinary Surgeons have devoted considerable research to
the elucidation of the anatomy and physiology of the foot, and many
old errors have been corrected. School Boards have made the present
generation of farriers able and willing to supplement their practice
by a study of principles. We have, in fact, arrived at a time when
everyone interested seems inclined to recognise the importance of the
art and its technical difficulties, and when no one has a brand new
infallible discovery which alone can save the horse and guide the
farrier.

My object in writing is not to suggest anything new but to point out
the general principles upon which the art is based, and to indicate
those details which are essential to success, and those which are to
be avoided if soundness and duration of service are recognised as true
economy in a stud of horses.

CHAPTER II.

THE FORM AND ACTION OF THE FOOT.

The foot of a horse consists of a variety of living structures,
differing in form and texture, and enclosed in a horny covering called
the hoof. Although the farrier's work is applied only to the hoof it is
necessary that he should know something of the whole foot, because it
is but too easy to injure the structures within by alterations of the
horny covering without.

The simplest way to understand the foot is to study separately the
different parts, and to apply that knowledge in obtaining a general
idea of the relations of all the parts to each other. There is not then
much difficulty in appreciating the functions of each part, and the
uses and action of the whole organ.

THE HOOF.

Everyone is familiar with the general appearance of the hoof. It is not
a regular geometrical figure. Each of the four feet of the horse shows
some peculiarity in form, by which a farrier can at once identify a
fore from a hind or a left from a right.

The fore feet should be similar in size and shape. Disease may be
suspected when any marked difference exists. But a healthy hoof which
has been broken, or much rasped, does not retain its proper form and
may thus confuse a novice.

The hind feet should be proportionate in size to the fore, and then it
is not of much practical consequence whether the whole are large or
small.

The front feet are rounder and less pointed at the toe than the hind;
they are also more sloping in front. The two fore feet and the two hind
should be in pairs. The right and left feet are distinguished from each
other by the inner side being more upright or, if examined on the under
surface, by the outer border being more prominent.

Although to a casual observer the hoof appears as one continuous horny
structure, it may easily be separated into three distinct parts by
prolonged soaking in water. The division takes place so as to leave the
sole, frog, and wall separate portions. These may now be considered.

[Illustration: Fig. 1.--A Fore Foot.]

[Illustration: Fig. 2.--A Hind Foot.]

=The Wall= is that portion of the hoof seen whilst the foot rests upon
the ground. It covers the front and sides of the foot. It extends
from the coronet downwards and slightly outwards so that its lower
circumference is greater than its upper. The front portion shows its
greatest height and obliquity, diminishing in these respects as it
passes backwards. At the heels the wall is turned in upon itself, and
passes forward towards the centre of the foot until it becomes lost in
the structure of the sole. These turned-in portions of the wall are
called _the bars_, and serve two purposes; they increase the bearing
surface of the wall, and by embracing a part of the sole on each side,
they afford an increased solidity to the union of the wall with the
rest of the hoof.

If we detach the wall its inner surface is seen to consist of a number
of thin horny projections running parallel to each other from above
downwards and forwards. These are called the horny laminæ. They number
from five to six hundred and correspond to similar processes on the
sensitive foot. (Fig. 3).

[Illustration: Fig. 3.--Half of a Hoof, showing the inside.]

Round the upper circumference on the inside of the wall is a depression
or groove presenting innumerable small pits or openings. This
corresponds to a part of the sensitive foot called the coronary band,
which will be noticed again.

A section of wall enables us to see variations in its thickness. (Fig.
4). It is thickest at the toe, becoming gradually thinner towards the
heels; thus affording strength and solidity to resist wear at one part,
as well as pliancy at another to ward off concussion.

[Illustration: Fig. 4.--Transverse Section of Wall showing variation in
thickness.]

The structure of the wall is fibrous--the fibres running parallel
to each other, and with the same obliquity as that presented by the
front of the wall. Although the wall varies in thickness from before
backwards, it does not from above downwards. It maintains the same
thickness from the coronet to its lower circumference.

The layers of the wall are hardest externally, becoming softer as they
approach the inner surface--a condition due to the outer layers being
exposed to friction and evaporation. This is a simple and valuable
provision of nature which should not be interfered with. The hard outer
layer is best adapted to withstand wear, and its density protects the
deeper layers from evaporation. This maintains the whole wall at the
degree of softness and toughness which best preserves elasticity and
strength of horn.

=The Sole= is that division of the hoof which forms the floor of the
foot. It is situated within the lower border of the wall, and is
slightly arched so that on a hard level surface its central part takes
no bearing. (Fig. 5). Posteriorly the sole is divided by a triangular
space into which the frog fits, and thus its continuation to the heels
consists of two angular portions embraced between the bars and the
wall. The unmutilated sole is throughout of nearly equal thickness,
but a slight excess round the circumference gives firmer attachment to
the wall.

[Illustration: Fig. 5.--The Sole with Frog removed.]

The inner surface presents a finely pitted appearance which is most
marked at the toe and round its border. The part immediately related
to the frog shows few pits, and we shall find that the whole surface
corresponds to the sensitive parts to which it is attached.

The structure of the sole is, like the wall, fibrous; but the fibres
are smaller. They run downwards and forwards in the same direction as
those of the wall. The outer layers are the hardest and protect the
deeper from injury.

=The Frog= is the smallest division of the hoof, and is a triangular
shaped body filling up the space left between the bars. (Fig. 6). Its
broad base is rounded and prominent, and is continued laterally by a
thin layer which binds together the heels and envelopes the back of the
foot. This thin layer is continuous with a horny band extending round
the upper part of the wall at its junction with the hair, and sometimes
prolonged downwards on the surface of the wall. (Fig. 7). It appears
to be a continuation of the outer layer of the skin, analogous to the
free border of skin at the root of the human nail. (Fig 8). It serves
the useful purpose of covering and protecting the young horn of the
wall at its source of growth.

[Illustration: Fig. 6.--The Frog, detached from the Sole.]

[Illustration: Fig. 7.--The Frog and frog-band.]

[Illustration: Fig. 8.--The frog band detached from wall by a small
wedge.]

The point of the frog, much the harder part, extends forward to the
centre of the sole. Though situated between the bars the frog is only
attached to their upper border--the sides remaining free and separate.
Thus on each side is formed a deep fissure which permits the frog to
expand laterally when compressed, without such force being continued to
the sides of the foot. The frog is elastic, and when pressed upon must
expand slightly. If these spaces between frog and bars did not exist,
the foot would be injured when the frog was compressed by the weight of
the horse--either the sensitive parts within would be bruised or the
heels would be forced apart.

The centre of the frog presents a depression or "cleft" caused by
the doubling in of the horn. Few shod feet exhibit it of natural
appearance, and the term cleft, by implying a narrow deep fissure,
keeps up the false notion. The cleft should be shallow and rounded.
It serves two purposes--it increases the mobility of the frog, and by
breaking the regularity of surface affords a secure foot-hold on level
ground.

The prominence of the frog might lead a superficial observer to
consider it a thick solid mass; and I believe this mistake is the cause
of its too frequent mutilation. It is merely a layer of horn following
the outline of the structures within, which are similarly prominent and
irregular in surface. (Figs. 9 and 10). The diagrams show a section
through the point and through the cleft of the frog.

[Illustration: Fig. 9.--Section of Foot at cleft.]

[Illustration: Fig. 10.--Section at point.]

The frog is fibrous, though not to such a marked degree as the other
portions of the hoof. Its chief qualities are elasticity and toughness.

THE SECRETING STRUCTURES.

If we macerate a dead foot in water for a week or two, the hoof may be
removed entire without injuring the tissues within. In this way the
sensitive foot or "quick" is exposed to view, and presents an exact
counterpart of the inside of the hoof. The sensitive foot consists of a
layer of fibrous tissue stretched over the bones and other structures
which form the centre of the foot. It is plentifully supplied with
blood-vessels and nerves necessary to its double function as the source
of horn growth and as the tactile organ of the foot. Horn is, of
course, not sensitive, although the slightest touch on a horse's hoof
is recognised by the animal, and this feeling is due to the impression
made upon the sensitive foot. In the living horse any injury to the
"quick" causes the greatest pain, and although this sensitiveness is
a serious disadvantage in disease it is a most valuable provision in
health, enabling the horse, even through a thick layer of horn, to
recognise the quality of the surface upon which he may be standing or
moving. It is this sense of touch--this tactile function--which demands
that the sensitive foot should be so bountifully supplied with nerves.

Every farrier knows how profusely blood flows from any wound of the
"quick"--evidence that the part is well supplied with blood-vessels.
This full supply of blood is not merely for the ordinary waste and
repair which takes place in every tissue; it is to meet a special
demand--to supply the material for the production of horn. The
sensitive foot is the secreting structure of the hoof, and the source
of the constant growth and reproduction of horn. It corresponds with
great exactness to the inside of the hoof, and as we have described the
hoof in sections it may be convenient to follow that course with this
structure, and to describe the _sensitive frog_, the _sensitive sole_,
and the _sensitive laminæ_. We shall begin with the last.

=The Sensitive Laminæ.= Corresponding to the horny leaves on the
inside of the wall, the sensitive foot presents an arrangement of
minute parallel folds which are called the sensitive laminæ. (Fig.
11). Between these the horny laminæ rest, so that there is a kind
of interleaved attachment which affords the very firmest connection
between the wall and the sensitive foot. If the laminæ be laid bare in
a living horse by removal of the wall, it is found that they have the
power to secrete a kind of horn, not a hard fibrous horn like that of
the wall, but a softer variety. This function is not very active in
health or we should find that the lower edge of the wall was thicker
than the upper; but it exists, and is very evident in some cases of
disease.

[Illustration: Fig. 11.--Foot with hoof removed showing at the upper
part the Coronary band, and below the Sensitive Laminæ.]

In laminitis the wall at the toe is often pushed forward out of
position by a horny mass formed by the laminæ, and so we have the
deformity of an excessive length of toe. In some cases of long
continued sandcrack the irritation of the laminæ causes excessive
secretion, and a horn tumour results. The sensitive laminæ, then,
fulfil two functions; they offer a firm connecting medium for the
wall, and they secrete horn. By the cruel experiment of removing the
horny sole and frog of a living horse and then forcing him to stand on
the maimed foot on a level surface, it has been shown that the laminæ
are capable of alone supporting the weight of the animal. It has been
argued from this that the laminæ always support the weight, and that
the horse's foot may be described as being slung by the connecting
laminæ. This is not true. The frog and sole help to support weight, and
the hoof acts as one continuous whole, each part taking its direct and
proportionate share of the weight placed upon the foot. The sensitive
laminæ are not elastic, they are unyielding, and, therefore, allow no
downward yielding which would impose excessive pressure on the sole.

=The Coronary Band.= (See Fig. 11). The sensitive laminæ do not cover
the whole of the upright portions of the sensitive foot. There is
between their upper extremity and the line which separates the skin
from the sensitive foot, a convex band which runs round the upper
border of the foot, and is turned downwards and inwards at the heels.
This is called the coronary band, and corresponds to the groove which
we noticed on the inner side of the upper border of the wall. On its
surface are innumerable small projections or papillæ which, in the
living animal, fit into the openings on the groove of the wall. From
each of these papillæ grows a horn fibre, and from the surface between
them is formed a softer horny matter--the two products forming together
the substance of the wall. The coronary band is, then, an important
structure, being the source from whence the wall is produced. Upon the
healthy condition of this band depends the soundness of the wall, and
any interference with its integrity must lead to defects or deformities
in the wall.

=The Sensitive Sole= (Fig. 12) is that portion of the "quick" to which
the sole is attached. Its surface is covered with papillæ, like those
on the coronary band but much smaller, giving an appearance somewhat
like the pile of velvet. From these the horn fibres of the sole are
formed, and a firm means of connection is afforded for the floor of the
hoof.

[Illustration: Fig. 12.--Under Surface of Foot showing Sensitive Frog
and Sole.]

=The Sensitive Frog= in structure resembles the sensitive sole, but its
papillæ are very much smaller, and the surface therefore is smoother.
The irregular prominent surface of the frog, with its cleft and the
space at each side of it, is exactly reproduced on the sensitive frog,
as might be expected, for the one is moulded on the other. There is
one difference between the sensitive frog and the other portions of
the sensitive foot which I may here mention. It is not attached to
the bones of the foot except by its point, but is situated behind the
bone, and has as a basis a mass of soft tissue which forms an important
cushion or pad, to be referred to later.

GROWTH OF HOOF.

Like every other part of an animal body, the hoof is constantly
changing. Wear and tear cause waste of the horn, which is replenished
by growth. When wear exceeds growth the foot becomes denuded of horn,
and lameness results. When growth exceeds wear the hoof becomes
disproportionately long, and some parts suffer by the overgrowth of
others--for instance, whenever the heels are unduly high the frog
becomes small and weak. In a state of nature the horse's foot keeps
itself of proportionate form. On hard ground the hoof is worn away
as quickly as it grows. On soft ground it may, for a time, become
overgrown, but this is rectified by the soft horn becoming fractured
and broken off. In enclosed cultivated grounds the movements of the
horse, even on grass land, are too limited to ensure a proportionate
form of hoof. When horses are turned out without shoes the feet should
not be left to take care of themselves, unless the pasture is of large
area and the time at grass extends for several months.

In a hoof which is overgrown--and all shod feet become overgrown in
four or five weeks--there is apparently a greater excess of horn at
the toe than elsewhere. This is due to the oblique direction of the
wall at the toe, and to the fact that the horn fibres of the hoof do
not grow down vertically, but obliquely forward. When the natural wear
of the hoof is prevented, the effect of growth is to lengthen the toe
and carry forward the bearing surface of the foot. Now this bearing
surface has a proper relative position to the limb above it. Therefore
a disproportionate foot must injuriously affect both the action and
position of the whole limb.

The rate at which the wall grows varies greatly in different horses,
and is affected by external conditions. The good average wall grows
nearly one inch in three months, and the whole hoof is replaced in from
ten to fifteen months. The hoof grows more rapidly when a horse is
actively exercised than when he is confined in a box. Febrile diseases
check growth, and irregularities of the system cause the formation
of ridges in the horn, each one commencing at the coronet and being
carried down with the growing horn until the hoof is marked by a series
of rings running transversely and parallel to each other. These rings
are of themselves no detriment to a horse, but they mark irregularities
of growth which may have been due to illness or lameness.

The growth of horn on a shod foot is affected by the bearing it takes.
When a part of the wall takes no bearing on the shoe it grows quicker
than that which does. We see this when a shoe is so fitted that the
heels take no direct pressure on the shoe, also when a portion of wall
is broken at the quarters, and again when, for any reason, a portion of
the edge of the wall has been rasped away to prevent bearing upon some
special spot. In all these cases, after the shoe has been worn a month,
it will be found that the horn has grown more rapidly at the part where
bearing did not take place, and, when the shoe is removed, the horn
which was relieved of pressure is found to have been in apposition with
the shoe.

The growth of horn cannot be accelerated by any application to its
surface. If we desire to hasten growth of the wall we can do so by
stimulating the part from which it is produced, _i.e._, the coronary
band. A mild blister to the coronet causes considerable increase in
the rapidity of growth, but no ointments applied to the surface of the
wall affect its production in the least, though they may modify its
condition and prevent dryness and brittleness.

The sole grows in much the same way as the wall, but it wears quite
differently. It never becomes overgrown to the extent seen in some
instances of the wall. The hard firm structure of the wall, if not worn
down by friction on roads or dry hard surfaces, may grow to a great
length. As a rule, when much overgrown, it splits in the direction of
its fibres and becomes detached in broken fragments. The sole, when
overgrown, has a tendency to become detached in flakes, and never very
much exceeds its normal thickness without becoming dry and brittle,
when the movements of the horse cause it to break up and fall off.

The frog when it takes a bearing on the ground wears off in shreds. A
frog which takes no bearing dries up, and sometimes a large superficial
layer is cast off. Though the softest of the horny divisions of the
hoof, the frog is able to withstand wear and tear as well as any of
the others. Being elastic and resting upon soft tissues, it is able to
yield to any undue pressure and leave the firmer horn of the wall and
bars to sustain the greater strain. The growth of the frog depends a
great deal upon the form of the back parts of the wall. If the heels
become overgrown, the frog is removed from bearing and consequently
wastes. High heels have always between them a small frog. On the other
hand low weak heels have always a large frog, and the explanation
is that the increased bearing thrown on the frog causes greater
development.

=Properties of Horn.= Horn is light, hard, tough, and elastic,
properties most essential to its usefulness as a protector of the foot.
Horn is porous, and absorbs moisture. Too much moisture in horn weakens
it, and therefore it must be remembered that the natural protection
against this is the hard outer layer of the hoof. When this layer is
rasped off moisture is more easily absorbed until the dry, hard surface
is restored by exposure and friction.

Horn is a bad conductor of heat, and thus an equally good protective
against the effects of snow in some countries, and of hot dry sands
in others. With a sound thick hoof the application of a red-hot shoe
produces very little effect on the internal structures, provided,
of course, it remain in contact only a reasonable time. With a foot
protected by a thin layer of horn, fitting a red-hot shoe must be done
quickly or it may damage the soft tissues.

DISSECTION OF THE FOOT.

So far we have only described the outer covering of the foot and the
structure from which it grows and by which it is connected to the parts
within. A little deeper examination is necessary to understand the
mechanism of the whole organ.

[Illustration: Fig. 11.--Section of Foot.]

If we divide into two lateral halves a foot cut off at the fetlock
joint, we have a section which should show the whole of the deeper
structures. In the centre we see the three lower bones of the limb--the
pastern, coronet, and pedal. (Fig. 11). On the front surface of these
bones we notice a tendon or sinew which comes from above the knee and
is fixed to the upper part of the pedal bone. At the back of the bones
two very large tendons run down and are fixed on the last two bones.
These tendons are the structures through which the movements of the
foot are made. They have in themselves no power of contraction but they
are connected above the knee, and in the hind leg above the hock, to
powerful muscles which possess the power of contraction. When these
muscles contract the tendons are drawn up towards knee or hock, and so
move the foot backwards or forwards.

To permit movement of one bone upon another the ends of the bones are
suitably shaped, and covered with a layer of gristle or cartilage. To
limit the movement and to hold the bones together the ends of each bone
are surrounded by ligaments, and thus we have joints formed.

[Illustration: Fig. 12.--Side view of Pedal Bone.]

The pastern bone is altogether above the level of the foot, the coronet
bone is partially within the hoof, and the joint between it and the
pedal bone is quite within. The pedal, often called the coffin bone,
(Fig. 12) is entirely within the hoof and fills the front part of
the horny envelope completely. It is a peculiarly shaped bone, being
continued backwards by two projections which follow the course of the
wall to a little beyond the quarters of the foot. (Fig. 13). From
this point to the extremity of the heels the wall is not supported by
bone but by strong plates of gristle, which are called the lateral
cartilages.

[Illustration: Fig. 13.--Under surface of Pedal Bone.]

[Illustration: Fig. 14.--The Lateral Cartilage.]

=The Lateral Cartilages= are situated one on either side of the foot
partly within and partly without the hoof. They form the basis upon
which the back part of the wall is moulded, and being elastic permit
a certain amount of movement in the posterior parts of the foot.
(Fig. 14). If the coffin bone filled the whole hoof, the foot would
be too rigid. With bone at the front portion we have a firm surface
for attachment, and with cartilage at the back we have an equally
firm attachment, but one that will yield to blows or pressure and
thus better protect the internal parts. These cartilages extend above
the level of the hoof, and may be easily felt in the living horse at
the back part of the coronet. (Fig. 15). Between them, and behind
the body of the coffin bone is a large space which is filled up by a
mass of soft tissue to which various names have been given, such as
plantar-cushion, frog-pad, etc.

[Illustration: Fig. 15.--Coffin Bone and Lateral Cartilages seen from
above.]

=The Frog-Pad= is the name under which we shall notice it. It forms
the bulbs of the heels and is the soft basis upon which is spread the
sensitive frog. It extends from side to side of the foot between the
two lateral cartilages, and fills up all the space within the hoof
behind the body of the coffin bone. The structure of this pad may be
described roughly as consisting of a network of fibrous bands, having
the interstices filled up with elastic tissue. (Fig. 16). Down the
centre of the pad runs a vertical partition of inelastic fibres; from
this strong fibrous bands pass to each cartilage, and so the whole of
the back part of the foot is tied together. The heels and quarters may
be pressed together to some extent, but they are prevented from being
forced asunder by the fibrous connections of the frog-pad. During
progression the downward movement of the coronet bone is provided
for by this soft pad, and so is an upward movement of the frog when
excessive bearing is placed upon it.

[Illustration: Fig. 16.--Section of foot showing the frog-pad and at
each side the cut edge of the lateral cartilage.]

The frog-pad serves other purposes besides those we have just referred
to. It is essentially a cushion or pad to prevent jar or concussion,
but it also plays an important part in the action of the foot, as we
shall see later on.

=The Coronary Cushion or Pad= is another mass of tissue of a similar
nature to the frog-pad. It is situated just above the upper border
of the hoof, and gives to the coronet its prominence and elasticity.
At this part of the foot there is an enormous number of small
blood-vessels and nerves, and the coronary pad forms not only a base
for these to rest on but a necessary protection for them. If instead of
this elastic bed they were placed merely between the skin and the hard
bones and tendons of the part, they would be injured by every slight
bruise. Even with this cushion, we have in practice very many serious
conditions following bruise of the coronet.

=Blood-vessels of the Foot.= It is not necessary to describe the
course of these vessels. All we need remember is that every part of
the tissues within the hoof is very plentifully supplied with blood,
and that the flow of blood is most rapid when the foot is in action.
In a dead foot from which the blood has escaped a certain amount of
movement of the bones within the hoof is easily effected. In the
living foot when every vessel is filled with blood no such movement
takes place. The blood in the vessels forms a sort of waterbed which
assists in preventing concussion and which distributes evenly over the
whole organ the pressure applied when weight is thrown on the foot.
In studying the dead foot with a view to understand its mechanism we
must not lose sight of the difference which results from having in one
case the blood-vessels empty, and in the other--the living animal--the
blood-vessels full.

THE FOOT AS A WHOLE.

The details I have given of the structure and uses of each separate
part of the foot will, I hope, be sufficient to enable us to understand
the form and action of the organ as a whole.

No one part of the foot is of greater importance than another, each is
dependent for its highest development and soundest condition upon the
integrity of neighbouring parts.

A weak wall allows of the flattening and spreading of the sole, whilst
a weak sole permits contraction of the wall. Overgrown heels cause
wasting of the frog, but low weak heels are usually accompanied by
excessive development of frog.

The special function of the foot is to sustain the weight of the
animal whilst standing or moving. The horse standing squarely on all
four feet rests his weight chiefly on the lower circumference of the
wall. On level ground the sole, on account of its arched form, takes
no direct bearing, but if sole and wall be sound a proportion of all
pressure applied to the wall is transmitted to the sole. So also must
all weight imposed on the arch of the sole be transmitted, through its
abutments or union with the wall, to the wall. If the sole be so thin
that it yields to pressure then its proper action is destroyed, and
instead of acting like an arch and supporting weight imposed on it, it
yields and injury results. The arched form of the sole indicates that
it was not intended to take a direct bearing on hard ground. On a soft
surface the edge of the wall sinks and the whole under surface of the
foot takes a direct bearing. Pressure of the sole on the soft surface
does no harm because it is diffused evenly over the whole of the sole.
We take advantage of this when the wall is diseased or injured, and
we desire to throw on the sole a larger share of weight. We turn such
animals out into a soft field or stable them on sand or saw-dust. Any
system of shoeing founded upon the true form and action of the foot
must recognise the arch, and not endeavour to force the sole to take a
bearing for which it is not adapted. There is only one part of the sole
which should act as a bearing surface, viz., that outer border which
is firmly joined to the wall. This part--the abutment of the arch--is
destined by nature to take a bearing and through it the whole of the
sole supports its share of weight.

The frog takes a bearing on the ground but it has a weight sustaining
function quite secondary to the harder and firmer parts of the hoof.
It is formed of a softer horn, and it has above it only soft tissues
which permit yielding. The frog then, when weight is placed upon it
by the standing horse, recedes from pressure, and leaves the heels
(wall and bars) to sustain the primary weight. Wall, sole, and frog,
each take their share in supporting weight, but this function is
distributed over them in different degrees, and it is fulfilled by each
in a varying manner. During progression the foot is repeatedly raised
from and replaced on the ground. It has not only to support weight but
to sustain the effects of contact with the ground at each step, and
the effects of being the point of resistance when the body is carried
forward and the foot is again raised from the ground.

What part of the foot comes first to the ground? Many different answers
have been given to this question. It has been said by some that the toe
first touches the ground, by others that the foot is laid flat down,
and by a few that the heel is the first part to come in contact with
the ground. Fortunately it is not now necessary to argue this question
on a purely theoretical basis. Instantaneous photography has shown that
on level ground, at all paces, the horse touches the ground first with
the heel. This fact gives significance to the structural differences
we find between the front and back portions of the foot. At the back
part of the foot we have the wall thinner than elsewhere, we have the
moveable and elastic frog, the lateral cartilages, and the frog-pad. We
have in fact a whole series of soft and elastic structures so arranged
as to provide a mechanism best adapted to meet shock and to avoid
concussion. Whilst drawing heavy loads, or ascending or descending
hills, the horse may vary his action to suit the circumstances,
and then we have the exception which proves the rule--then we have
sometimes the heel, sometimes the toe brought first to the ground.

At the time when the foot first touches the ground, the leg is extended
forward and the pastern is in the same oblique position to the shank
as when a horse is standing. This obliquity of the pastern is another
safeguard against concussion, and it renders impossible the first
contact with the ground at any point other than at the heel. As the
leg becomes straightened, the weight of the body is imposed upon the
foot, but the greatest strain arrives just before the toe leaves the
ground, for then there is not only weight to sustain, but the friction
to be borne which results from the toe being the fulcrum upon which
falls the whole effect of the muscular effort necessary to raise and
carry forward the body of the animal. The front part of the foot is
structurally well adapted for its use. It presents the thickest and
strongest part of the horny covering, and, as an inside basis, it
has the unyielding coffin bone. Thus we have at the toe strength and
rigidity--at the heels strength and elasticity.

Another important point in the action of the foot is implied by the
question--does it expand when weight is thrown on it? The principles of
horse-shoeing require that this question should be answered. There are
those who say that the foot does not alternately expand and retract as
weight is placed upon or removed from it. There are others who assert
that the expansion of the foot is an important natural function that
must be provided for in any system of shoeing. It is agreed by most
observers that at the upper border of the hoof, more particularly
at the heels, expansion does occur. It is when we come to the lower
border of the foot that the statements are most conflicting. Ordinary
measurements taken at this part with calipers or by tracings on paper
of the foot when raised from the ground and when resting upon it, show
no variations in the width of the foot. These methods of measurement
are not sufficiently delicate to be trustworthy. Experimentalists
in Germany and in this country have recently used an apparatus by
which the slightest variations are detected by electrical contact,
and the results are very interesting. These experiments show that
in a well-formed, healthy foot the hoof throughout its posterior
two-thirds does expand to pressure, and perhaps that the arch of the
sole is slightly flattened. This expansion is, however, comparatively
slight--about equal to the thickness of a sheet of writing paper--and
may practically be disregarded in considering the best methods of
shoeing sound feet.

One result of these experiments is to show what an important part the
frog plays in the foot, and also how the action of one part depends
upon the conditions of others. When the frog rests firmly on the ground
and weight is placed upon the foot expansion occurs, especially at the
upper or coronary border of the hoof. When the frog does not touch the
ground and weight is imposed upon the foot, contraction occurs. The
explanation of this difference seems to be as follows. When weight is
placed upon a foot, the coronet bone is depressed upon the soft mass of
the frog-pad. With a sound frog taking a bearing upon the ground, the
frog-pad cannot descend, and the compression to which it is therefore
submitted causes it to bulge laterally and so expand the back of the
foot. When the frog does not reach the ground and weight is placed
upon the frog-pad, there is nothing to prevent it yielding downwards,
and in so doing the fibrous bands connecting together the two lateral
cartilages of the foot are depressed and the cartilages drawn
together--hence the contraction of the foot. No better illustration
could be given of the unity of all parts of the foot, and how one or
many parts may suffer if the structure or function of one be defective.

There is one more movement of the hoof which is possible and which
must be referred to, as it has been made the basis of a grave error in
shoeing. I have said the back part of the foot is elastic and yielding.
If you examine a shoe, so applied to a foot that an inch or more of its
extremity has no contact with the hoof, you will find that when weight
is rested on that foot the horn yields downwards and comes in contact
with the shoe. This simply demonstrates that when there is nothing to
support it the horn at the heels may be forced downwards. It is not a
normal action, and in an unshod foot cannot occur on a level surface.
The effect of this downward movement of the heels is to put a strain on
the horn of the quarters. A shoe so fitted as to permit this evil is in
common use, and no fault is more serious than thus forcing an unnatural
action upon the hoof at every step. With unintentional irony this piece
of bad work has been called "easing the heels."

In concluding this chapter, I would just repeat that the natural
bearing surface of the horse's foot is the lower edge of the wall and
that portion of the sole immediately in union with it; that the arch of
the sole should not be in contact with the ground; that the frog ought
to have a bearing on the ground, but ought not to be so prominent as
to unduly share in sustaining weight. This natural bearing surface is
what we want to utilize in shoeing. We put on a shoe _merely to prevent
excessive wear of the hoof_. If we can protect the wall the frog can
take care of itself, and we have only so to apply our shoe that we do
not damage any useful structure or interfere with any natural function.

NOTE.--No person is expected to learn the structure of a foot
entirely from this description. He must obtain two feet cut off
at the fetlock joint. One he should soak in water till the hoof
can be pulled off. The sensitive foot is then visible and the
inside of the hoof; with these before him, the drawings and
descriptions in this chapter will be of great assistance. The
second foot he should have sawn vertically down the middle through
the point of the toe, and again across the quarters, so as to show
the inside of the foot from two different points of view; this
will afford a view of the relation of parts.

CHAPTER III.

PREPARATION OF THE FOOT.

The cheap wisdom of the amateur is often expressed in the remark "the
shoe should be fitted to the foot, not the foot to the shoe." Like
many other dogmatic statements this is only the unqualified assertion
of half a truth. Foot and shoe have to be fitted to each other.
There are very few horses whose feet do not require considerable
alteration before a shoe can be properly fitted to them. As a rule,
when a horse arrives at the forge, the feet are overgrown and quite
out of proportion. In a few cases--as when a shoe has been lost on a
journey--the foot is worn or broken and irregularly deficient in horn.
In either instance the farrier has to make alterations in the hoof to
obtain the best bearing surface before he fits a new shoe. The claim
often made for some novel inventions in horse shoes, "that they may be
fitted and applied in the stable by a groom or stableman" is evidence
of a sad misunderstanding of the art of horse-shoeing. If shod feet
always remained of the same shape replacement of shoes would be a very
easy matter--but they never do. The living foot is constantly changing,
and therefore the man entrusted with fitting shoes to it, must know
what its proper form should be. When he finds it disproportionately
overgrown he must know how much horn to remove--where to take away
and where to leave alone. He must not carry in his head a theoretical
standard of a perfect foot and attempt to reduce all feet to that
shape. He must make allowance for varieties of feet, and for many
little differences of form that present themselves in practice. He has,
in fact, to prepare the foot for a shoe, and it is just as important
to do this properly as it is to prepare a shoe for the foot. To fit a
shoe to a foot which has not been properly prepared may be even more
injurious to the horse than "to fit the foot to the shoe."

The general principle to be followed is--to remove superfluous horn,
to obtain a good bearing surface for a shoe, to bring all parts of the
hoof equally into proportion. A good foot so prepared, when the horse
is standing on level ground should show, when looked at from the front,
both sides of the wall of equal height; the transverse line of the
coronet should be parallel with the line of the lower border of the
hoof, and

the perpendicular line of the leg should cut those lines at right
angles. (Fig. 17). When looked at from the side the height of the heels
and the toe should be proportionate. When looked at from behind the
frog should be seen touching the ground. On lifting the foot a level
bearing surface wider than the wall should be presented, extending from
heel to toe all round the circumference of the hoof; within this level
border, the sole should be concave, strong, and rough.

[Illustration: Fig. 17.]

In Fig. 17 is shown the foot on its ground surface and from the side.
The parallel lines are quite arbitrary, but assist in explaining how
the proportion of the foot is to be attained. Both sides of the foot
are of the same height. The bearing surface just meets the middle line.
All the lines at coronet, heel, and toe, are at right angles to the
perpendicular line. The side view shows the proportionate height of
heel and toe, and the slope of the wall in front. Compared with Figs.
22 and 23 deviations from proportion are seen.

These conditions are not attainable with all feet, but the prudent
farrier does the best he can under the circumstances. It is easy to
make the frog touch the ground by over-lowering the heels, but this is
only introducing one evil in attempting to avoid another. Some feet
have naturally a long toe with an excessive slope of the front part
of the wall. To hide this defect a farrier may "stump up" the toe and
leave the heels too high, but he does so at the expense of the horse's
foot. Each foot requires treating with full knowledge of the form best
adapted to its natural formation, and most capable of carrying a shoe.

=The Instruments= used to prepare a foot for shoeing are a rasp, a
drawing knife, and a toeing knife.

The rasp is the most indispensable. It should be sixteen inches long,
proportionately broad, and one part of it should be a file-surface. The
shorter, narrow rasps do not afford all the advantages a farrier should
possess to enable him to do the best work. To strike an even all-round
level bearing surface on a hoof a farrier requires a large rasp, just
as a joiner must have a large plane to produce a level surface on wood.
Harm may be done by the careless use of a rasp, and a bearing-surface
spoiled by the over-reduction of horn at one place. This fault may be
aggravated by attempts to mend it, if such attempt take the form of
further reduction of the whole hoof on a foot where horn is deficient.

The drawing knife is a comparatively modern instrument which replaced
a tool called the buttress. A drawing knife is formed with great skill
for the purpose of paring out the concave sole of the hoof, and has
done infinite harm. In the days which have now almost passed away,
when it was thought the proper thing to make the hoof look clean,
smooth, and pretty, the drawing knife was the chief instrument in
the preparation of the foot. Now, when nearly all men know that the
stronger the sole and frog of the foot can be preserved the better
for the horse, this knife is less used--and the less the better. The
doorman, preparing a foot for the fireman to fit a shoe to, should
not use a knife at all. The man who fits the shoe requires a knife to
remove occasional little prominences of horn which are liable to cause
uneven pressures or which are in the way of a properly fitted shoe--as,
for instance, the edge of the wall to make way for a clip, or the angle
of sole at the heel to prevent uneven pressure by the shoe.

The toeing knife usually consists of about a foot of an old
sword-blade. This knife is held and guided by one hand of the farrier,
whilst with the other it is driven through overgrown horn by the
hammer. Skilfully used it is unobjectionable, and for the large strong
hoof of heavy draught horses it saves a great deal of time and labour.
For the lighter class of horses it is unnecessary, and for weak feet
with a thin horn covering it is dangerous.

The toeing knife cannot leave a finished level bearing surface, and
its work has to be completed by a few strokes of the rasp. A farrier
should, therefore, never attempt to remove all the superfluous horn
with the knife, he should leave some for the rasp so that in producing
the final level surface no encroachment upon the necessary thickness of
covering horn need be made.

[Illustration: Fig. 18.]

=The overgrown foot= such as we find on a healthy horse that has
retained a set of shoes for some weeks, or that has been without
shoes on a surface not hard enough to cause sufficient wear, is quite
unfitted to receive a shoe. It must be reduced to proportions. In
Fig. 18, I have attempted to show diagrammatically a side view of
an overgrown hoof. The dotted lines at the base show two effects of
lowering one part more than another, although both attain a level
surface. In Fig. 21 we see the result of over-lowering the heels, and
in Fig. 20 of leaving them too high. It may also be noticed that these
conditions affect other parts of the foot; in fact not only other parts
but the whole foot, and even the relative position of the foot to the
leg. If we compare the proportionate foot, Fig. 19, with the diagram
Fig. 21, it will be seen that by over-lowering the heels the slope
of the front of the foot is increased, that the bearing surface from
heel to toe is slightly increased in length, and that if the dotted
perpendicular line be accepted as showing the direction through which
the weight of the body passes, lowering the heels tends to put an
increased proportion of weight on the back parts of the foot. If we
compare Fig. 19 with Fig. 20 we see the effect of leaving the heels too
high. The bearing surface from heel to toe is shortened, the slope of
the wall at the toe is made less, and more weight is thrown upon the
front parts of the foot.

[Illustration: Fig. 19.--A proportionate hoof.]

[Illustration: Fig. 20.--A disproportionate hoof--heels too high.]

[Illustration: Fig. 21.--A disproportionate hoof--heels too low.]

Now these alterations in both cases affect not only the form of the
foot but its relative position to the leg, and as the bones of the
limb above are a series of levers connected by muscles and ligaments
so placed as to be most efficient for movement, it is evident that
alterations of the foot must affect the action of the limb. (Compare
Figs. 19, 20 and 21) In the unshod horse roaming about there is a
natural automatic return to proper relative position whenever it has
been temporarily upset. A long toe is worn down and high heels are
reduced to their proper level by friction. Not so a foot protected by
an iron shoe. Wear is stopped, and a disproportionate hoof becomes more
and more disproportionate. Temporary alterations of the position of the
foot do little harm because they are permitted, within a margin, by the
movement of joints and by the elasticity of muscles. When, however, an
alteration of position is continued for many weeks it tends to become
permanently fixed and may thus do a great deal of harm, which is not
traced to its real cause because the effect is slow and gradual. It is
important, therefore, to remember that the proportion of the hoof is
to be maintained not only because it is necessary to the well-being of
the foot; but because it affects the action of the whole limb. Too long
a toe may cause a horse to stumble, and it must always increase the
strain on the back tendons during progression. Heels too high prevent
the frog from taking its proper bearing on the ground, and thus cause
a loss of function in the back parts of the foot. An excessively high
heel has a tendency to throw the knee forward and to straighten the
pastern.

[Illustration: Fig. 22.--Heels high--under surface and side view.]

[Illustration: Fig. 23.--Heels low--toe long.]

It is impossible to lay down any hard and fast rule to guide a
farrier in maintaining the proportions of heel and toe when reducing
an overgrown hoof to proper form. Feet differ much in their natural
formation, some are high-heeled and some low, some are straight in
front some very much sloped, some are narrow and upright, others round
and spreading. In Fig. 22 the heels are too high, and the bearing
surface does not reach the transverse line at the heels. The side
view shows the excessive height of heels and the slope of the wall in
front too upright. Great assistance is afforded the farrier in judging
whether he should remove more horn from heel or toe by the appearance
of the under surface of the foot. When the heels are much above the
level of the frog there is an indication for their lowering. When the
wall and bars are about flush with the angle of sole between them,
there is, as a rule, no more horn to spare at that part. The length of
the toe may be usefully gauged by the condition of the junction between
wall and sole. When the sole is sound and strong all the wall above its
level--wall unsupported by sole and showing on its inner aspect marks
of the horny laminæ--may be rasped down so that a firm bearing surface
is obtained consisting of wall and sole.

In Fig. 23 the bearing surface at the heels is below the line marking
a proportionate foot. The toe is too long and projects beyond the
transverse toe line. The side view shows the low heel and the
corresponding excess in the slope of the wall in front. The lower
transverse line in each figure does not represent the ground, but is
added to make clear the height of heels and length of toe.

Important as it is to maintain the relative proportions between the
front and back parts of the foot, it is perhaps even more important
to preserve the balance between the two sides of a foot. Both sides
must be left of equal height. If one side be higher than the other a
disproportionate amount of weight is thrown on the lower side, and more
or less strain is put upon the ligaments of the joint above. In the
Figs. 24 one limb is shown with both sides of the hoof even, and the
straight line of the limb cuts squarely across the transverse line of
the bearing surface of the foot. In the the other limb one side of the
hoof is too high, and in the preparation for shoeing only that side
will require attention.

[Illustration: Fig. 24.]

Through constant neglect of this point some feet become more or less
permanently twisted--and the twist occurs at the coronet. The ground
surface of a foot or a shoe always tends to remain at right angles to
the direction of the limb, and when the sides of a hoof are allowed to
remain of unequal height, the higher side presses the soft tissues of
the coronet upwards. As the hoof grows from the coronet the side thus
increased in height is not so noticeably uneven at the lower border of
the wall as at its upper, and it cannot be restored to its proper form,
except by months of careful attention and slight over-lowering at each
shoeing. The diagrams (Figs. 25 and 26) represent vertical sections
through a foot from side to side. One shows the wall uneven at the
base, the other shows it uneven at the coronet.

[Illustration: Fig. 25.--Uneven at ground surface.]

[Illustration: Fig. 26.--Uneven at coronet.]

Peculiarities in the formation of a limb sometimes cause an apparent
error in the relative position of the foot. Thus we have horses that
turn their toes in, and those that turn their toes out. The cause of
this twist takes place at the upper part of the limb, and it will be
found that when the toes turn out the elbow turns in and _vice versâ_.
The farrier can do no good to this formation, and attempts to alter
it or disguise it by devices in shoeing are only injurious to the
foot,--little deceptions worthy of a horse-coper.

=A good bearing surface= is the primary object aimed at in preparing
the foot for a shoe. The relative position of the limb to the foot
and the proper proportions of every part of the foot are matters to
be borne in mind whilst the farrier is directly forming the bearing
surface for a shoe. A good bearing surface must be even, level, on
sound horn, and as wide as can be obtained to give stability to the
shoe. It should not be limited to the wall. If, without over-reduction,
the use of the rasp leaves a firm portion of the sole as a level
surface continuous with the lower edge of the wall, the best of bearing
surfaces is obtained. (Fig. 27). The bearing surface should be level
from heel to toe, and no part of it can be singled out either as unfit
to bear weight or as specially capable of enduring undue pressure. No
broken or diseased horn should be used as bearing surface for a shoe.
The broken horn should be removed and the diseased horn must, if not
entirely removed, have so much of its border cut or rasped off as will
prevent contact with a shoe.

[Illustration: Fig. 27.]

After forming a level bearing surface with the rasp the sharp outer
border of the wall is lightly removed with the file, so as to prevent
splitting of the horn. The outer surface of the wall should not be
rasped for it affords protection to the deeper layer of horn. The
harder the outer layer of horn is kept the tougher and firmer is the
whole thickness.

=The Sole and Frog= require very little attention. No sensible farrier
now puts himself to the unnecessary trouble of cutting away horn
that is wanted for protection. It was not the practical farrier that
introduced the stupid "paring and cutting" that ruined horses' feet for
nearly a century. It was the theorists, who taught expansion of the
wall and descent of the sole as primary necessities in the function of
a foot, who must be credited with all the evils resulting from robbing
the sole and frog of horn. When a horse is shod with an iron shoe the
wall cannot wear, and therefore it has to be artificially reduced at
each shoeing. But the shoe does not interfere with the wear of a frog,
and the farrier may safely leave that organ entirely to take care of
itself. To some extent the shoe does interfere with the natural wear of
the sole, and, therefore, any flakes of horn which have been prevented
by the shoe from detaching themselves from the sole may be removed.
The best way to remove these is with the buffer. The sole should not
be pared out. I mean not only that the horn should be left strong,
it should not be pared with a drawing knife, even if only a harmless
surface layer be removed. The effect of leaving the sole of a shod foot
with a smooth, level, pared surface is to stop its natural method of
throwing off more or less broken flakes, and to cause it to retain that
which is half loose until it is removed in one great cake.

A portion of the sole that requires a little special care in preparing
for shoeing is the angle between the wall and the bars--the well-known
seat of "corn." This must not be left so as to come in contact with
the shoe. It is not to be "scooped" out, but it should be reduced
distinctly below the level of the wall so that when the shoe has been
in position for a week or two there is still no contact between the
horn of the soles and the iron at that point.

=Level or adjusted surface?= The bearing surface of a hoof must, of
course, be exactly adapted to the surface of shoe intended to be
applied. Presuming that the best surface for a shoe is one level from
toe to heel, I have insisted upon the necessity of a level bearing
surface on the foot. There are, however, exceptional cases in which a
level shoe is not used, and then we must alter the foot accordingly.
Horses that wear the toe of a shoe out of all proportion to the rest
of the iron may be beneficially shod with a shoe turned up at the toe.
To fit such a shoe the hoof surface must not be made level, it must be
rasped away at the toe and rounded off to follow the line of the shoe.
In the three diagrams (Fig. 28) is shown--(_a_) side view of a foot
prepared to suit the turned-up shoe at the toe, (_b_) a level line to
fit a level shoe and, (_c_) a form often adopted on the Continent to
suit a shoe fitted with a slight curve throughout. This adjusted shoe
is designed to imitate the shape of the worn surface of an old shoe
or to some extent the worn surface of an unshod foot. Every farrier
knows how many horses go better after a level shoe has been worn a few
days than when first applied, and it is argued, with reason, that the
greater ease is due to the shoe being worn to the form offering least
resistance to the movement of the foot in locomotion. I have nothing to
say against this form of shoe and the necessary form of foot surface
for it, except that it is more difficult to make than the ordinary
level one. When adopted the curve of the foot should not be obtained by
over-lowering the toe and heels but by leaving the quarters higher.

[Illustration: Fig. 28.--Three forms of bearing-surface.]

FAULTS TO BE AVOIDED.

Fig. 29 shows a hoof in which shortening of the toe has been effected
not by reducing the ground surface of the wall, but by rasping away the
wall in front of the toe. This should not be done with any good foot,
but it may be adopted with feet having an unnaturally long toe and no
superfluous horn on the under surface. A "stumped-up" toe is very ugly
and it weakens the hoof in front.

[Illustration: Fig. 29.--A "stumped-up" toe.]

=Uneven bearing surfaces= are easily produced by a careless use of the
rasp. One side of the wall may be made lower than the other, one heel
may be reduced more than the rest of the foot, or one side of the toe
may be unevenly reduced. In Fig. 30 the foot presents an uneven surface
which not uncommonly results from careless work. The parts over-reduced
are those most easily reached with a rasp. The near foot suffers at
the outside heel and inside toe. The off foot at the inside heel and
outside toe. A left handed farrier would injure the feet in just the
opposite positions.

[Illustration: Fig. 30.--Uneven surface.]

Another fault results from holding the rasp untruly. If we suppose the
inside heel of the near foot to be under preparation and the farrier
inclines his rasp too much inwards, he leaves the wall at the heel
lower than the sole within it. On such a foot a level shoe rests upon
the sole instead of upon the wall, and a bruised heel soon follows.

=Paring away the sole= to produce a deep concave appearance has another
evil effect in addition to that before pointed out. It removes the horn
just within the border of the wall, taking away the natural support,
and leaving as bearing surface for a shoe a narrow ridge instead
of a strong flat surface. Fig. 31 shows this fault, and it must be
remembered that this ridge may be left as thin as a knife edge. Such a
ridge cannot sustain the weight of the horse, and when it yields the
shoe also yields, the clenches are raised and the shoe becomes loose.

[Illustration: Fig. 31.--A Pared-out Sole.]

=Excessive rasping of Wall.= The best farriers--those most proud of
their work--have a great temptation to use a rasp too freely to the
outer surface of the wall. The hoof gets rough, or it may be ridged,
its appearance is improved by being made smooth, and it is only human
to turn out work which is clean and neat. Owners and grooms are rather
inclined to forget the claims of the horse when judging shoeing,
and the result is that some harm is done by excessive rasping. A
strong foot does not suffer much, but its strength is preserved by
leaving the hard outer surface intact. Rasping off an outer layer of
horn favours evaporation and hardening of the underneath layer, and
the toughness so desirable is to some degree replaced by hardness
and brittleness. Excessive rasping below the clenches is even more
injurious than rasping above them. The wall, between its bearing
surface and the clenches, has to withstand the contact of the shoe, and
the perforation by nails. It should be the toughest and strongest part,
and, therefore, should not be rasped more than is necessary to lay down
the clenches and finish the fitting. Unfortunately the neatest work
is done by fitting a shoe "close" and then rasping off any protruding
horn. This is bad for the foot, as it weakens the wall and spoils the
bearing surface at each shoeing. The worst offenders in this direction
are dealers, who sacrifice everything to appearances and insist upon
shoeing being neat at all hazards.

=Opening the Heels= is one of the gravest faults a farrier can be
guilty of. It consists in cutting away the extremity of the wall at
the heel and generally a slice off the side of the frog at the same
time. The effect is to produce an appearance of width at the back of
the foot--to make what is called "a fine open foot." Fig. 31 shows a
foot which has been injured in this way. The wedge shaped opening which
results has many objections. It breaks the continuity of structures
at the heels, it removes horn unnecessarily, it weakens the foot and,
when the wall is interfered with, it shortens the bearing surface for a
shoe. The bearing surface at the back of the foot is perhaps the most
important of any afforded by the wall. The longer the bearing surface
is at the heels the more the base for sustaining weight is brought
under the leg, and the better the position for supporting the body. All
removal of horn that shortens this surface is injurious.

=Over-reduction of hoof= is always a fault. It is true a carefully
fitted shoe on a foot so treated may do no harm for a time. Too much
horn should be left rather than too little. A strong covering of horn
is a protection against many mistakes in the fitting or form of a
shoe applied to a foot. So long as a hoof is everywhere strong enough
to sustain pressure and afford bearing, weight is evenly distributed
throughout the whole foot. When the horn is thin it yields to any
uneven pressure and damage is done to the foot, even if immediate
lameness is not induced.

CHAPTER IV.

THE FORM AND MANUFACTURE OF SHOES.

Horse-shoes are made either by hand or machinery. In this country most
are hand-made--the front shoes from new bar-iron, and the hind from
old shoes welded together and drawn out under heavy hammers. Probably
no method of working iron gives such good results as this in producing
a hard, tough shoe that will withstand wear. The custom of the trade
is to keep a stock of shoes suitable for all the regular customers.
From this stock are selected sizes and forms, which are then specially
fitted for each foot.

Various materials have been tried in the production of horse-shoes.
Leather, compressed and hardened, has been tried, and failed.
Vulcanite was experimented with unsuccessfully. Paper, or more
correctly, a compressed _papier maché_, has also been tested but proved
unsatisfactory. Steel has been pretty largely tried in many different
forms, but it is difficult to temper. As nearly all shoes are applied
immediately after being fitted they have to be rapidly cooled in water,
and steel treated in this way is made so hard that, if the shoes do
not break, they are dangerously slippery on most paved streets. As a
material for shoes good malleable iron has no equal. It can be obtained
in bars of various sizes to suit any form and weight of shoe, and the
old shoes made from it may be worked up over and over again.

The chief objects to be attained in any particular pattern or form of
shoe are--that it be light, easily and safely retained by few nails,
capable of wearing three weeks or a month, and that it afford good
foot-hold to the horse. All shoes should be soundly worked and free
from flaws.

The first shoes were doubtless applied solely to protect the foot from
wear. The simplest arrangement would then be either a thin plate of
iron covering the ground surface of the foot, or a narrow rim fixed
merely round the lower border of the wall. Experience teaches that
these primitive forms can be modified with advantage, and that certain
patterns are specially adapted to our artificial conditions. A good
workman requires no directions as to how he should work, and it is
doubtful if a bad one would be benefitted by any written rules, but it
should be noted that a well-made shoe may be bad for a horse's foot,
whilst a very rough, badly-made one may, when properly fitted, be a
useful article. To make and apply horse-shoes a man must be more than
a clever worker in iron--he must be a farrier, and that necessitates a
knowledge of the horse's foot and the form of shoe best adapted to its
wants.

=Weight of Shoes.= The lighter a shoe can be made the better. Weight
is a disadvantage we are obliged to put up with to obtain wear, for
the frequent removal of shoes is only a little less injurious to the
hoof than working with none at all. It is not to be understood that
the heaviest shoe gives the most wear; on the contrary, a heavy shoe
may have the iron so distributed as to increase the rapidity of wear,
and a shoe of half the weight properly formed may last longer. It is
no uncommon thing to find worn-out shoes still weighing more than a
new shoe which will, on the same horse, give a longer period of wear.
When a horse wears his shoes out very rapidly, the indication to the
farrier is not simply to increase the weight, but to see if he can
obtain more wear by altering the form and distributing the iron in a
different way. A tired horse wears his shoes much more rapidly than a
fresh and active one. Continued slipping wears away a shoe out of all
proportion to the work done by a horse having a firm foot-hold. These
two different conditions may be partially due to the shoes, for a heavy
shoe tires the leg, and broad flat shoes favour slipping. Some horses
wear one special part of the shoe excessively--as a rule, either at the
toe or the heel--and this is better met by turning up the worn part out
of the line of wear than by thickening it and so increasing weight.
Besides, a heavy shoe requires a greater number or a larger size of
nails to retain it securely in position, and this is a disadvantage.
It has often been asserted that a horse "goes better" in a heavy shoe
than a light one, and that this is due to the heavier shoe acting as a
protection to the foot and warding off concussion. If the term "goes
better" merely means that he lifts his foot higher and consequently
bends his knee more, I do not deny the assertion. The reason of this is
not that the horse feels less concussion and therefore goes freer. It
is an exaggeration of the natural movements, due simply to the horse
with weight imposed on his feet having to use the muscles of his arms
more to lift that weight. The same thing can be brought about by tying
bags of shot on to the hoof, which is done to cultivate "action." The
healthy foot requires no artificial aids against concussion, but when
a foot becomes tender from bad shoeing it may sometimes be relieved by
adding to the substance and weight of a shoe.

The following are about the average weights, per shoe, of horses
standing 16 hands high:

Race Horses 2 to 4 ounces.
Hacks and Hunters 15 to 18 "
Carriage Horses 20 to 30 "
Omnibus " 3 to 3-1/2 lbs.
Dray " 4 to 5 "

=Thickness and Width of Shoes.= To obtain the necessary amount of wear
from shoes they must be increased either in thickness or width, and it
will assist us in estimating the relative value of these conditions
if we shortly consider their advantages and disadvantages. I may say
at once that no sound foot requires a wide shoe merely as "cover"
or protection for the sole. Defective soles may sometimes require
protection, but sound ones never, and we may therefore put aside
entirely all claims made for width of shoe under pretence that it gives
a valuable protection to the foot. A shoe should be as wide as the
natural bearing surface of the foot, so that it may occupy the whole
of the space offered by nature as useful for bearing. Even when it is
wider no harm is done until the width is such as to afford a lodgement
for stones, etc., between the concave sole and the web of the shoe.

A thick shoe raises the foot from the ground and thus removes the frog
from bearing--a very decided disadvantage. It also requires the larger
sizes of nails to fill up the deep nail holes, and very often renders
the direction of the nail holes a matter of some difficulty.

The width of a shoe may beneficially vary. It should be widest at
the toe to afford increased surface of iron where wear is greatest.
It should be narrowest at the heels so as not to infringe upon the
frog, nor yet to protrude greatly beyond the level of the wall. The
thickness of a shoe should not vary unless, perhaps, it be reduced in
the quarters. Heel and toe should be of the same thickness so as to
preserve a level bearing. Excess of thickness at the toe puts a strain
on the back tendons, whilst excess at the heels tends to straighten the
pastern.

=The surfaces of Shoes.= There are two surfaces of the shoe which
claim attention, one which is applied to the foot, and another which
rests on the ground. The form of these surfaces may be varied greatly,
but of course the foot-surface presents much less necessity and less
opportunity for alterations than the ground-surface. The foot-surface
of a shoe must be formed in accordance with the requirements of
the horse's foot, and no other consideration should be allowed to
materially modify it. The ground-surface may be altered to suit the
tastes and prejudices of the owner as well as the requirements of the
horse and the peculiarity of roadways.

[Illustration: Fig. 32.--A level, flat bearing-surface.]

=The Foot-Surface.= It is quite obvious that the surface of the shoe
upon which the hoof has to rest should be regular and even; that it
should not consist of hills and holes or grooves and ridges. I should
not have mentioned such a very evident matter but that in large towns,
the cheaper and poorer classes of shoeing commonly possess this very
fault. When shoes are made from thin, wide, old iron tyres they are
"buckled" on one surface, and to hide this the farrier puts that side
to the foot so that it is not noticed until it causes damage. There
are three or four forms of foot-surface adopted by farriers, all of
which have distinctive features, and some of which have very grave
evils. There is the plain flat surface which is given to all narrow
shoes, to hunting shoes, and to some heavier and wider shoes. So long
as the sole is healthy and arched this is a very good form. All hind
shoes have a flat foot-surface, and most fore shoes might have it with
advantage. It utilises the whole of the natural bearing surface, and
must of necessity afford a firmer basis for the foot to rest upon than
a more limited surface. The fore feet are not so constantly arched in
the sole as the hind. Sometimes they are flat and occasionally convex.
If a shoe be intended for use on all feet--on feet with convex and flat
soles as well as those properly formed--a wide flat foot surface would
often cause injury by pressing unevenly upon the sole. To avoid this
injury in less than five per cent of feet, and to save the trouble of
keeping in stock shoes of different forms, the flat foot-surface of
front shoes has been replaced by a bevelled or "seated" surface. (Fig.
33).

[Illustration: Fig. 33.--A "seated" bearing surface.]

This form is very widely used. It consists of a narrow flat surface
next the outer circumference of the shoe, about equal in width to the
border of the wall, and within that, of a bevelled surface, sloped
off so as to avoid any pressure on a flat sole. This "seated" surface
is not positively injurious but it limits the bearing to the wall,
and neglects to utilise the additional bearing surface offered by the
border of the sole. If shoes were to be made all alike no shoe is so
generally useful and safe as one with a foot-surface of this form,
but it is evident that when the sole of the foot is concave there is
nothing gained by making half the foot-surface of the shoe also concave.

There are two other forms of foot-surface on shoes. In one the surface
slopes gradually from the outer to the inner edge of the shoe, like
the side of a saucer. In the other the incline is reversed and runs
from the inner edge downwards to the outer. This last form is not
often used, and was invented with the object of spreading or widening
the foot to which it was attached. The inventor seemed to think that
contraction of a foot was an active condition to be overcome by force,
and that expansion might be properly effected by a plan of constantly
forcing apart the two sides of the foot. The usual result of wearing
such a shoe is lameness, and it achieves no good which cannot be as
well reached by simply letting the foot alone.

[Illustration: Fig. 34.--Foot-surface sloped outwards.]

[Illustration: Fig. 35.--Foot-surface sloped inwards.]

The foot-surface which inclines downwards and inwards like a saucer
acts in an exactly opposite way to the other. The wall cannot rest
on the outer edge of the shoe, and consequently falls within it, the
effect being that at every step the horse's foot is compressed by the
saucer-shaped bearing. This form of surface (Fig. 35) is frequently
seen, and is at all times bad and unnecessary. Even when making a shoe
for the most convex sole it is possible to leave an outer bearing
surface, narrow but level, which will sustain weight without squeezing
the foot.

[Illustration: Fig. 36.--Foot-surface level at Heels.]

At the heels the foot-surface of all shoes should be flat--not
seated--so that a firm bearing may be obtained on the wall and the
extremity of the bar. No foot is convex at the heels, therefore there
is no excuse for losing any bearing surface by seating the heels
of a shoe to avoid uneven pressure. Fig. 36 rather exaggerates the
"unseated" portion of shoe.

=The Ground-Surface.= As I have said, this may vary indefinitely.
Sometimes it is a plain flat surface, broken only by the holes made for
nails or by the "fullering" which affords not only space for the nails
but some grip on the ground. When a shoe is "fullered" the groove made
should be deep, so as to let the nail-head well down, and wide so as to
afford room for giving the nail a proper direction. If the fullering
be continued round the toe of a shoe by a good workman neatness is
given, but when a clip is drawn the iron is so reduced that some wear
is sacrificed. If only an inch at the toe be unfullered, the solid iron
affords more wear just where it is wanted.

[Illustration: Fig. 37.--Concave ground-surface.]

The concave shoe, often described as a hunting-shoe, presents a very
different ground-surface from that just referred to. It rests upon
two ridges with the fullering between, and on the inner side of these
the iron is suddenly sloped off. This shoe is narrow and flat on the
foot-surface, and is specially formed to give a good foot-hold and to
be secure on the hoof.

[Illustration: Fig. 38.--Double-grooved ground-surface.]

A Rodway shoe has two longitudinal grooves and three ridges on its
ground-surface. The outer groove carries the nails, and the inner
groove lightens the shoe and increases the foot-hold. It is not
the number of grooves or ridges that prevents slipping; it is the
absence of a continuous flat surface of iron, and the existence
of irregularities which become filled up with sand and grit. A
four-grooved shoe has no more anti-slipping properties than a
three-grooved, and a one-grooved shoe is as good as either, although it
cannot stand the same amount of wear.

Transverse ridges and notches have also been tried as ground-surfaces
for shoes, but offer very little, if any, better grip than the
longitudinal grooves. Their great disadvantage is that they cannot be
made deep enough without weakening the shoe, whilst if shallow they are
worn out before the shoe has been long in wear.

[Illustration: Fig. 38.--Ground-surfaces, notches, projections, ridges.]

=A Calkin= is the name given to the extremity of a shoe when turned
down at the heels. Calkins are used on most hind shoes and, in some
parts of the country, on fore shoes. They are supposed to be the
most convenient and effective means of giving good foot-hold. This
supposition is correct when a horse travels on soft ground or on
streets so paved that a space is left between each course of stones.
They are of very little use on asphalte or wood pavement, and not much
more use on roller-made macadam. With light modern carriages and level
modern roads calkins are quite unnecessary, and better means of giving
foot-hold may be substituted. It is a fact that horses when shoes are
new and calkins prominent do their work without slipping, and that
when the calkins are worn down the horse moves with less confidence
and security. This does not prove that calkins are necessary. It must
be remembered that horses possess a power of adapting themselves
to circumstances, but having learned to rely upon any artificial
assistance they are the more helpless, for a time, on its withdrawal.
Calkins assist the horse for a time, but after the calkin is worn
down the horse is in a worse position than if he had never become
accustomed to its assistance. Of course on soft ground, especially
grass, calkins afford a firmer grip than any other contrivance. On the
other hand, their constant use lifts the frog out of bearing and causes
it to waste, thus spoiling the action of the natural provision against
slipping. Level shoes on the hind feet promote sound, prominent frogs,
and give firm foot-hold for all light horses. Even omnibus horses,
now that the vehicles are supplied with effective foot-brakes, may
advantageously be worked without calkins. On country roads, especially
when the district is hilly or the load is heavy, calkins may be
requisite, and must then be made to do as little harm as possible.

[Illustration: Fig. 39.]

The wear of a shoe is affected by the height of a calkin. The more
the heel is raised the greater the amount of wear at the toe. Many
shoes when worn out at the toe show very little effects of wear at
other parts, and the question arises how best to increase the wear
of the shoe without increasing its weight. In Fig. 39 three diagrams
are presented in which dotted lines show the effect of wear. At (_a_)
the shoe is of even thickness throughout--from heel to toe--and the
line of wear shows that when the shoe is worn out a great amount of
iron remains. At (_b_) the quarters of the shoe are made thinner and
the toe is made thicker, so that with no increase of weight but by a
better distribution of the iron, increased wear is provided for at
the part where it is most required. At (_c_) is shown a shoe similar
in form to that at (_b_) but differently fitted. The toe is turned
slightly upwards, and the result is that a larger portion of iron
is brought into wear. In the case of very hard-wearing horses that
scrape out the toe of the ordinary shoe in ten or fourteen days this
form of fitting adds considerably to the durability of the shoe, and
so preserves the foot from the evil of too frequent removal of shoes,
whilst avoiding any increase of weight. Without calkins wear is more
evenly distributed, and the toe is not worn away disproportionately to
the rest of the shoe.

[Illustration: Fig. 40.--Two calkins--the low square one preferable.]

A calkin throws the leg and foot, to some extent, out of their
proper position. A very high calkin is not only objectionable, it
is unnecessary. Not much prominence is required to afford a catch
or stop. Excessive height is usually given to meet wear, and this
can be obtained equally well by increasing the width and breadth. I,
therefore, recommend that when calkins are used they should be low,
square and broad. The further under a foot the calkin is placed, the
greater is the raising of the heel, therefore calkins should always be
accompanied by a long shoe. The further back a calkin be placed the
less it interferes with the natural position of the foot.

Calkins render a horse liable to tread the opposite foot, and the
higher and sharper the calkin the greater the injury inflicted. To
avoid this injury the inner heel of a shoe frequently has no calkin,
but is made at the same level as the outer by narrowing and raising
the iron at the heel, forming what is called a wedge heel. This is not
an advisable form of shoe as it has on the inner heel a skate-shaped
formation, most favourable to slipping, and on the outer a catch--an
arrangement tending to twist the foot each time the catch takes hold of
the ground. If calkins are used at all they should be of equal height
and on both heels of the shoe.

In Scotland, and in the North of England, heavy horses are shod, fore
and hind, not only with calkins but also with toe-pieces, and the
owners assert that the horses could not do the work without them. That
horses do similar work in the South without calkins and toe-pieces
rather shakes one's faith in the assertion, but it must be remembered
that nearly all paved streets in the North have a division left between
the rows of stones in which the toe-piece finds a firm resisting
surface. I believe also that the average load drawn is greater in the
North than in the South. One thing in favour of toe-pieces must be
acknowledged--they, with the calkins, restore the natural position of
the foot and preserve the level of the shoe. On the larger draught
horses the toe-pieces permit a lighter shoe to be used, as the portion
of iron between heels and toe need not be thick to resist wear. It only
requires to be strong enough to support weight and much less iron is
therefore used.

The heavy dray horse of the North, shod with toe-pieces and calkins, is
never worked at a trot. In London all horses are trotted--a proceeding
which reflects discredit upon the intelligence of the managers.

I must mention another objection to calkins. They increase the tendency
to "cut," and many horses will cease "cutting" after calkins are
removed and a level shoe has been adopted.

=Nails and nail holes.= It is necessary to consider these together
as they are dependent on each other. Shoes were first nailed to the
feet by flat-headed nails, and probably it was a long time before the
wedge-headed nail was thought of. When the nail head fits into the nail
hole it may retain the shoe till it is worn as thin as a penny, but if
only the shank of the nail enters the shoe, the head is soon worn off
and the shoe becomes loose. Within the last 20 years the horse-shoe
nail trade has been revolutionised by the introduction of machinery.
Machine-made nails are now almost entirely used, and the three or four
leading brands are as near perfection as were the very best hand-made.
Practically there is no fault to find with them, and as they are
ready-pointed for driving they save time and labour in the forge. They
are made in various sizes, and numbered from 2 up to 16. Only the very
best iron can be used to produce good nails. Nothing is dearer than bad
nails which cause injury to the foot and loss of shoes.

[Illustration: Fig. 41.]

A good nail should present certain forms of head, neck and shank. The
head should not be too broad at the top or it may become fixed in the
nail-hole only by its upper edge, as shown in the middle diagram Fig.
41, and when the shoe has had a few days wear the nail loses its hold,
and the shoe is loose. The neck should not be too thick, as it is then
liable to press on the sensitive foot and to break the wall. The shank
should not be too wide or too thick. The point should not be too long
or too tapered as this leaves insufficient metal to form a good clinch.

There are two methods of putting nail-holes into shoes--by "fullering"
and by "stamping." A stamped shoe is one in which the nail holes are
merely punched at certain distances, so as to leave four-sided tapered
holes of the exact shape of a nail-head. A fullered shoe is one having
a groove round the circumference through which the nail-holes are
punched. Both processes, when well-done, admit of nails being driven
into the hoof with equal safety and ease.

Whether stamped or fullered, there are a few more important points to
remember about the nail-holes. The wall is not of the same thickness
throughout, but becomes thinner towards the heels. The inner side of
the foot is also somewhat thinner and more upright than the outer.
The safest position, then, for the nails is in the front half of the
foot, but should this position not present sound horn they may be
placed further back. The danger of placing nails near the heels is due
entirely to the greater risk in driving them through the thin horn.
There need be no fear of interfering with expansion.

The distance of the nail-holes from the outer edge of the shoe should
depend upon the thickness of the horn of the wall, and therefore be
greater in large shoes than in smaller, and greater at the toe than at
the heels of the same shoe. When the nail-holes are all near to the
circumference of the shoe (Fig. 42 B.) they are described as "fine";
when they are all placed far from the edge (Fig. 42 A.) they are called
"coarse." When the nail-holes are too "fine" a nail has to be driven
high up in the wall to obtain a firm hold, and this is liable to split
the horn. When nail-holes are too "coarse" the nail in driving goes
dangerously near the sensitive foot. The evils of coarse and fine
nailing depend a great deal upon the method of fitting the shoes. When
shoes are fitted full to the foot (when the outer circumference of the
shoe is greater than the circumference of the wall) "coarse" nail-holes
are brought to about their best position. When shoes are fitted close
(_i.e._, when their outer edge is brought within the border of the
wall) "fine" nail-holes are brought to their best position in relation
to the foot. It need hardly be added that the fit of a shoe ought not
to be subject to the position of the nail-holes, but that these should
be properly placed so that fitting be guided only by the requirements
of the foot.

[Illustration: Fig. 42.--Wrongly placed Nail-holes.]

Each nail-hole when properly placed--neither too coarse nor too
fine--should be punched straight through the shoe and not inclined
either inwards or outwards, except at the toe where the slope of the
wall is followed by slightly pitching in. When a fuller is used the
groove made should be wide; then the farrier has more command over the
direction of his nail. If the nail-hole be pitched in, the nail must
take that direction and is liable to wound the foot. If the nail-hole
be pitched out, the nail is prevented from taking sufficient hold of
the horn.

[Illustration: Fig. 43.--Nail-holes "pitched" in and out.]

The position and direction of the nail-hole control the passage of a
nail through a shoe and into the hoof. The man who drives a nail is
usually blamed for laming a horse, but in most cases it would be more
just to blame the man who made the nail-holes or fitted the shoe and so
rendered safe driving difficult or impossible.

Each nail-hole should be as far as possible from the other--say,
from an inch to an inch and a half apart. When the two front or toe
nail-holes are put too far back the whole are crowded, or the last are
pushed back too near the heels.

For small shoes four or five nail-holes are sufficient. Medium-sized
shoes should have from five to seven, and the heavy shoes of big
draught horses must have eight. The number of nail-holes need not
always be increased in proportion to the size of the shoe, because as
the weight of shoe is increased so is the size of the nail, and an
extra strong nail may take the place of additional ones. The fewer
nails in a foot the better, but as a properly-placed nail does no harm,
and as the loss of a shoe may be very serious, it is better to have one
too many than one too few.

[Illustration: Fig. 44.--Machine-made Shoe--Fore-foot.]

[Illustration: Fig. 45.--Machine-made Shoe--Hind-foot.]

=Machine-made Shoes.= Horse-shoeing is distinctly an art requiring
special skill for its proper performance. It is also one of the most
laborious of all skilled trades. Anything which lightens mechanical
toil tends to improve the mental and artistic qualities of the workman,
and all applications of machinery which lessen the heavy manual labour
of the farrier may therefore be looked upon as improvements. Machinery
has lightened the labour of shoe-making in two ways--by supplying
various patterns of grooved and bevelled iron in bars, which only
require cutting into lengths and turning round to form a shoe, and also
by making shoes all ready to be fitted to the foot. Machinery has not
yet turned out a shoe as good and durable and well finished as the best
workman can produce by hand, but it can produce many forms of shoes as
good for all practical purposes, and it has this advantage--all are
alike. Bad workmen make bad shoes, but a machine, once able to produce
a good model, can repeat it exactly, therefore machine-made shoes of
a proper pattern are superior to all but the very best hand-made
shoes. Economy, of course, is on the side of the article produced by
machinery, and all large firms keeping their own farriers find a great
saving by buying the ready-made shoes. Under conditions when shoes must
be fitted without a fire, as in coal mines, or in the case of armies
during a campaign, the machine-made article has the advantages of
regularity of form and a true level bearing surface.

[Illustration: Fig. 46.--Sections of rolled bar iron.]

In little shops where often only one man is at work, either
machine-made shoes or prepared bar iron offer great conveniences.
The prepared bars can be bought seated on the foot-surface and with
a single or double groove on the ground-surface. Very narrow bars
suitable for tips, "Charlier," or light hack shoes are now widely used,
and a special bar--flat on the foot-surface, concave to the ground--can
be obtained which only requires cutting into lengths and turning round
to form a first-class hunting-shoe.

[Illustration: Fig. 47.--Sections of light pattern bar iron.]

Both prepared bars and machine-made shoes must be judged by their form
and by the material used in their manufacture. Some are better than
others, but all have to contend with a large amount of trade prejudice
which has little basis except in the matter of the hind shoes--here
machinery has not yet reached perfection.

CHAPTER V.

SELECTION OF SHOES.

In practice, a farrier does not trouble much about the selection of
suitable shoes. The rule is to apply whatever form of shoe the horse
has been wearing, and only to venture an opinion as to alterations when
asked by the owner. When the selection of a suitable shoe is left to
the workman he takes into consideration the work required of the horse,
the form of the feet, and the wear of the old shoes. The form of the
old shoes indicates not only whether a horse is a light or hard wearer
but what parts of the shoe are most worn, and thus enables provision
to be made against excessive or irregular wear. The form of the feet
indicates not only what size of shoe is requisite but also what special
weakness or strength is to be encountered. It is also necessary to
note the condition of the fetlocks and knees, which may show signs of
"brushing" or "speedy cutting." According to all these appearances a
shoe should be selected. For the different classes of horse there are
well-known forms of shoe which present special advantages, thus:--

=The race horse= when in training, may be shod with a very light
shoe, but on the turf he requires the lightest contrivance capable of
protecting the hoof and affording good foot-hold. The ordinary racing
plate answers these requirements. It is made in a "crease," or tool, or
may be made from specially prepared bars which only need cutting into
lengths and turning round. The plate is about one-third of an inch wide
by one-eighth thick. The foot-surface is flat, and the ground-surface
is fullered and concave.

=Steeplechase= plates are made on the same pattern, but should be a
little stronger so as to avoid even the possibility of becoming twisted
on the foot.

=Hunting shoes= should be light, very secure, and of a form to give
good foot hold. The best are flat on the foot-surface, and fullered and
concave on the ground-surface. The hind shoe should also be concave on
the ground-surface, but to avoid the injury of over-reaching the inner
circumference at the toe should be rounded and smooth. A small square
calkin at each heel affords grip on grass, and especially in going down
hill at a fast pace.

=Hacks=, being used on hard roads, must have heavier shoes than
hunters, but the form may be the same.

=Carriage horses= require more substance in their shoes than hacks, and
the narrow concave shoes suitable for hunters and hacks cannot give
sufficient durability. The double-grooved shoe known as "Rodway's" is
the best for this class. On ordinary roads the hind feet may be shod
with a common two heeled shoe, but on wood and asphalte the heavier
sizes of Rodway iron make a shoe that affords very good foot hold and
dispenses with the necessity for calkins.

=Omnibus and Van horses= require stronger shoes to meet the hard wear
entailed by their work. The heavy Rodway iron makes very suitable front
shoes, but the hind shoes must be solid with only a fullering for the
nails or, as many prefer, each nail-hole separately stamped. As a rule
the hind shoes of this class of horse have calkins on the outside heel.
If the vehicle in which they run is provided with a foot-brake calkins
are unnecessary, and the advantages of a level shoe should be made use
of. The advantages are--better foot hold, longer wear and less danger
from treads and "cutting."

=Heavy draught horses.= In Scotland and in the North of England this
class of horse is shod with a toe-piece and calkins on both fore and
hind shoes. In London calkins are only put on the hind shoes, and
toe-pieces are not used at all. On paved streets where a space exists
between the rows of stones and especially if the road be hilly, I think
toe-pieces are advisable, and of course when they are used calkins must
be also made. Horses having become accustomed to toe-pieces, when shod
with a level shoe, slip much more for a week or two than do horses
which have never learned to rely upon the bar across the toe. Every
thing considered, I incline to prefer a level shoe in front, and a
shoe with two low square calkins behind for heavy draught horses. The
enormous width of shoe often used in London is quite unnecessary, it is
very heavy and it favours slipping. A narrower shoe must of course be a
little thicker to meet the wear, but it is lighter and affords better
foot hold, and as slipping and fatigue are both causes of excessive
wear, a narrow shoe, weight for weight, will last longer than a broad
flat one.

CHAPTER VI.

FITTING AND APPLICATION OF SHOES.

Having selected shoes suitable for the feet and adapted to the special
work of the horse, having also prepared the foot for shoeing, we arrive
at another important part of the farriers' art--fitting the shoe. No
matter what form of shoe be used or how the foot be prepared for it,
unless the two are properly fitted the horse does not obtain all the
advantages of good shoeing, and may be positively injured. The owner of
horses seldom knows anything about the fitting of shoes, and therefore
fails to appreciate how some of his directions concerning feet and
shoes are quite impracticable.

[Illustration: Fig. 48.]

I have in a previous chapter attempted to show how a foot should be
prepared for shoeing, and what bearing surface should be left for the
shoe. I have also described what I consider the best forms of shoe. The
object at all times should be to follow nature as closely as possible,
but it often happens that we may, with benefit, depart from the exact
indications given and still fulfil all essential requirements. If we
examine the unshod foot which has been worn down to proper proportions
we find the bearing surface is not level--it is worn more at the toe
and heels than elsewhere. If we examine the ground surface of an old
shoe the same thing is noticed--the surface is not level, the toe and
heel show most wear. The question then arises, should we make the
artificial bearing surface of the foot on the same plan and adjust the
shoe to it, as in Fig. 48, or should we make the surface level and
apply a level shoe as in Fig. 49? I believe that the ideal arrangement
would be to follow the line suggested by a worn foot or a worn shoe,
but it is difficult to carry out, and greater exactness of fit is more
readily obtained by two level surfaces. The ground surface of a shoe
may, if necessary, be altered to suit the outline of wear, whilst the
level foot-surface is preserved, as in Fig. 50.

[Illustration: Fig. 49.]

[Illustration: Fig. 50.]

Whatever form the farrier adopts, a shoe should rest equally
throughout, and the contact of foot and shoe should be exact over the
whole bearing surface. Assuming then that a properly prepared foot
presents a level surface, the fitting of shoes becomes simple so long
as the smith possesses manual dexterity and follows the indications of
common sense.

There are two conditions to be fulfilled, (1) to fit the shoe to the
plain surface of the foot, (2) to fit the shoe to the circumference of
the wall. Most amateurs judge shoeing by the way a shoe follows the
outline of the hoof, but the practical man knows that it is equally
difficult and important to fit the surface.

=Outline fitting.= A shoe is first compared with the foot, it is then
heated, and the heels cut off or turned down to the proper length.
Each limb of the shoe is fitted to follow the outline of the wall,
and it is necessary to warn the novice that the inside and outside
borders of a foot are not alike. The outside is rounder and fuller,
and the shoe should be shaped to follow exactly the direction of the
wall. The outer border of a shoe should always be as prominent as the
outer border of the hoof; it should never be within it. The inner
border must not protrude beyond the wall lest the opposite leg be
struck. A well fitted shoe must be fitted full to the foot. What is
called "close" fitting, _i.e._, bringing the shoe rather within the
circumference of the wall, is injurious, as it loses the best and
strongest bearing of the wall, and permits the farrier to give an
appearance of neatness by rasping away any horn which protrudes beyond
the shoe. On a well-shaped foot the shoe should follow the outer line
of the hoof from toe to heel, but where the heels of a foot are turned
inwards there is an advantage in fitting the shoe wider at the heels,
as by so doing the base of the foot is not constricted and a wider
resting surface is afforded to the limb. When a shoe is fitted wide at
the heels it is essential that the foot-surface of the shoe should be
level at the heels. If it be inclined, as it often is in seated shoes,
a very grave defect in the fitting results, for the heels have no level
bearing-surface.

A shoe fitted too wide is liable to be trodden off by the opposite
foot, or it may cause the horse to hit the opposite fetlock joint.

Provided the nail holes are properly placed, when the outside border
of the shoe is fitted nicely to the circumference of the hoof, they
are brought to their right position. When nail holes are placed too
near, or too far, from the outer border of the shoe--_i.e._, when they
are too "fine" or too "coarse"--it may be necessary to correct their
position by fitting the shoe "closer" or "fuller," as the case may be.
When a farrier fits shoes made by another man he may overlook this, as
we are all slaves to habit. The man who in his daily practice combines
"close" fitting with "fine" nailing has to alter his routine when
fitting a shoe with coarse nail holes.

The length of a shoe at the heels is a matter of more importance than
is generally recognised. As a rule hunters are all shod too short,
while most cart horses are shod too long. The objections to a long
front shoe are that it is liable to be trodden off by the hind shoe,
and that it may injure the elbow when the horse lies down. A long hind
shoe is free from both these disadvantages, and as it usually has a
calkin is the best form to adopt.

In fitting the heels of front shoes, in all but galloping horses, the
iron should generally extend slightly behind the extremity of the
horn. (Fig. 48). Horses used for galloping should have the end of the
shoe just within the termination of the horn, and should finish with
an oblique extremity. (Fig. 49). There is nothing gained by greater
shortening, if the iron be fitted exactly to the horn. Why shoes are
often pulled off, when only just the length of the hoof, is because
they are not fitted close enough, and very often because they are
wilfully and ignorantly designed to leave a space between hoof and
iron. This so-called "eased" heel is an unmitigated evil.

[Illustration: Fig. 49.--Shoe fitted short at the heels.]

=Surface-fitting.= It is simple to direct that the bearing-surface of
a shoe should be exactly adapted to the bearing-surface of a foot. It
is not so simple to carry out. When the horn on the lower surface of
a foot is thin any uneven pressure--_i.e._, pressure applied directly
to one spot--soon causes injury, pain, and lameness. When a good thick
layer of horn exists, uneven pressures are less injurious, because
the horn distributes them over a wide surface. Good workmanship is
displayed by leaving no uneven pressure, and by so fitting a shoe that
it shall do no harm. With a narrow shoe--one only the width of the
wall--no uneven pressure can be applied to the sensitive foot, but
such a shoe is seldom used as it is too light to afford sufficient
wear. A wide shoe with a flat foot surface is easily fitted on all
concave feet--_i.e._, on all hind and most fore feet. To make use of
the whole bearing-surface a shoe must rest evenly from toe to heel--the
flat surface of the shoe must take a level bearing on the whole flat
bearing-surface of the foot.

There are two places where injury from uneven pressure is most likely
to happen--at the toe and at the heels.

In preparing a foot the wall at the toe may, from want of care, be
reduced a little below the level of the sole, or in making a shoe the
inside border at the toe may be left higher than the outside. In each
case uneven pressure is placed on the sole just where the back border
of the shoe rests. In fitting a hot shoe, wherever the hoof is unduly
marked warning is given that pressure at that point must be prevented
by altering the surface either of the shoe or the foot. On a strong
foot, the knife may be used to remove a little horn; on a weak foot the
alteration must be on the shoe.

At the the heel uneven pressure is most frequent on the angle of sole
between the wall and bar, where it causes the so-called "corn"--a
condition in the horse having no analogy to the affliction similarly
named in the human subject. It is simply a bruise of the sensitive
parts under the horn.

A bruised heel--a corn--is most likely to arise from the use of a
shoe too short, especially if fitted too close. It may arise from a
properly-fitted shoe retained too long on the foot and shifted from
its proper bearing on the wall to an improper bearing on the sole. A
bruised heel may also result from the use of a well-made shoe if the
preparation of the hoof has been faulty. Rule-of-thumb directions to
"reduce the heels to a level by the use of the rasp, but on no account
cut away any sole" may result in injury. In a strong foot with an
overgrown sole it is easy to get a level surface and to fit on to it a
level shoe, but the horn of the sole does not remain level. As it grows
and flakes off the portion between the bar and wall is raised. If the
weather be wet it swells, and then, bound down by the shoe, it acts
simply as a stone might and bruises the sensitive parts within by its
uneven pressure. It is always safe and it is never injurious to remove
so much of the surface of this portion of sole with the drawing-knife
as will ensure no uneven pressure on it by the shoe.

[Illustration: Fig. 50.--An "eased" heel.]

The more exactly the shoe fits the foot-surface the more easily it is
retained in position by the nails, and the less likelihood there is of
any part of it pressing distinctly on a limited portion of horn. Exact
fitting allows all bearings and pressures to be distributed equally
over the surface of the hoof, and thus permits the shoe most nearly to
resemble a mere continuation of the hoof in iron--an arrangement to
prevent wear, but not to interfere with natural functions. There is one
departure from level fitting which requires special notice since it
is made, not by accident or negligence, but by design. It consists in
taking the bearing of an inch or an inch and a half of the extremity of
a shoe off the foot. (Fig. 50). It has been called "easing the heels,"
and the space permits a knife-blade, sometimes even a pencil, to be
placed between the shoe and the foot. It is one of the very worst
practices that theory has forced into horse-shoeing. Men who do it say
"the heels won't stand pressure." I reply they will stand all proper
pressure, and a good deal more than the quarters. But the practice
does not relieve the heels of pressure. If you examine a shoe fitted
in this way, after it has done a month's service, you will find it
sometimes polished bright, sometimes with a deep groove worn into it.
You may also test its bearing by raising the foot from the ground and
inserting between shoe and hoof a flat bit of wood, then on releasing
the foot and raising the opposite one, you will find that the bearing
is such that the bit of wood cannot be removed. The "eased heel" does
not relieve the heels of pressure but, instead of constant normal
bearing, it permits a downward movement of the back of the foot at each
step--which is unnatural, and which cannot occur in an unshod foot
on a level surface. The "eased heel" does more than this. It wastes
a large extent of good bearing-surface, and it concentrates pressure
at one point--where the shoe and foot meet--at the quarters. It loses
good bearing-surface where it is important to have it, and unevenly
throws extra weight on the quarters which are the weakest parts of the
wall. An "eased heel" has not one single advantage, but it has every
disadvantage which misplaced ingenuity could contrive.

[Illustration: Fig. 51.--Section of a seated shoe.]

For flat feet a wide shoe with a flat foot-surface is unsafe as there
is liability to uneven pressure on the sole. For such feet the safer
form of foot-surface is one presenting a level narrow bearing-surface
round its outer border, from which an inclined or bevelled surface
continues the shoe inwards. (Fig. 51) This form of shoe can be fitted
to nearly any kind of foot. To escape injury to a flat sole "seating
out" shoes is necessary, but the operation should always leave a level
bearing-surface for the wall. When a shoe is seated from one side to
the other so as to produce a saucer shaped surface harm is done to the
foot. Such a shoe presents no level bearing-surface, and the weight of
the horse pressing the wall on an inclined plane causes the foot to be
pinched or compressed in a manner which soon causes lameness. (Fig.
52). A few years ago these shoes were too common, and to make them
still more injurious, the foot was pared out from the centre to the
circumference like a saucer, and the two spoiled articles were fitted
together. Their surfaces of contact were two narrow ridges which even
the most expert workman could not fit without injury to the horse.

[Illustration: Fig. 52.--Section of a "saucer" shoe.]

In Fig. 52 a shoe with an inclined surface is applied to a foot with
a bearing-surface as wide as the wall but the only contact is at the
edges. The horn at the edge will yield, and the hoof be pressed inwards
as the weight of the animal forces the foot into the saucer-shaped
shoe. When the bearing-surface of the foot, instead of being as wide as
the wall, is only a ridge, the horn yields more rapidly, the clinches
rise and the shoe becomes loose.

In Fig. 53 is shown a section of another shoe with an inclined instead
of a level surface, but the slope is from within outwards. The effect
of this is exactly the opposite of the previous shoe. The wall is
forced outwards, and if it does not as a whole yield to the pressure
the portion in contact is broken. When this form of bearing-surface is
adopted at the heels of a shoe the two sides of the hoof are violently
forced apart, and it has even been recommended as a means of expanding
the foot; but forcible expansion is both unnecessary and dangerous.

Always regarding the shoe as an extension of the natural hoof in a
harder and more durable material, it is evident that the most stability
will be attained by the use of as wide a bearing-surface of foot and
shoe as is compatible with ease and safety to the horse.

In Fig. 54 is shown a section of a narrow shoe which takes a bearing
over the whole extent of its foot-surface.

[Illustration: Fig. 53.--Bearing-surface inclined outwards.]

[Illustration: Fig. 54.--Narrow shoe with level bearing-surface.]

In Fig. 55 is shown a shoe with as wide a bearing-surface as in Fig.
54, but which loses half its bearing because the foot-surface is too
narrow to utilise it.

[Illustration: Fig. 55.--Bearing-surface of foot too narrow.]

[Illustration: Fig. 56.--A good bearing-surface.]

In Fig. 56 we have a model bearing-surface on the foot, nearly twice
the width of the wall, and we have a shoe with a flat foot-surface
capable of using the whole bearing. Such is the fitting of all hind
shoes, and it might well be adopted with advantage in all fore shoes on
good feet.

=Clips= are thin projections drawn up from the outer border of shoes
for the purpose of giving greater security to their position on a
foot. On heavy cart horses the clips are sometimes of great size and
encourage the idea that the smith looks upon them as designed to assist
the nails to retain the shoe on the foot. They should have no such
purpose, their use being merely to prevent the shoe shifting to one
side. A clip should not be narrow and high, it should be low and wide
so that its bearing is taken against the lower edge of the wall. A high
clip is a most serious danger when shoes get loose and are trodden on
by the horse. The usual position for a clip is at the toe, but there
are occasions when two clips--one at each side of the toe--are used. On
some shoes a clip is placed at the outer quarter to prevent the shoe
being displaced inwards; this is more often required on hind shoes. A
clip at the toe affords some assistance in fitting a shoe exactly, and
it also affords steadiness to the shoe during the driving of the first
nails. In America clips are not used, and when American machine-made
shoes were first introduced into London they were fitted without clips.
I am bound to confess that these shoes did not shift on the feet to any
noticeable extent, but they are now all fitted with clips so I suppose
the workmen found they were an advantage. The greatest evil resulting
from clips is seen in slovenly fitting, when the farrier with his knife
carves out a great hole in the wall in which to imbed the clip. As a
clip is flat it cannot be fitted to the rounded face of the wall, but
all that is necessary is to reduce the round to a flat surface with the
rasp, so that the clip may rest on it, care being taken that at the
extreme edge the horn is not left so prominent as to be unduly pressed
upon when the clip is driven close to the wall. It is easy to lame a
horse by violently hammering up the clip, especially when the horn
behind it has been so much cut away as to leave only a thin protecting
layer. A clip should only be hammered up sufficiently to leave it
firmly applied to the wall. A bad workman in making his clip may spoil
the foot-surface of a shoe by causing a bridge on the bearing surface
of the iron at the toe, and this, on thin or flat feet, may cause
lameness.

A very unsightly appearance and very defective work results from the
fireman leaving his clip at right angles to the line of the shoe. It
should be inclined backwards at about the same slope as the portion of
wall against which it is to rest. The two diagrams (Fig. 57) illustrate
what is meant.

[Illustration: Fig. 57.--Toe Clips.]

=Hot and Cold Fitting.= When an engineer or a carpenter has two
surfaces to fit together with great exactness he employs some colouring
material to show where they do come in contact and where they do not.
When a farrier fits a shoe to a horse's foot he tests its adaptation by
applying it at a dull red heat to the horn. This proceeding shows with
precision the bearing surfaces, as the horn is charred in proportion to
the contact. If the shoe be found not to fit exactly, it is taken back
to the anvil and altered. It is then again for a few seconds applied
to the horn and the surface of contact examined. This proceeding is
repeated until sufficient exactness is arrived at and then the shoe
is cooled ready for nailing on. As horn is a bad conductor of heat
this process of "hot-fitting" does no harm to the sensitive structures
within the hoof unless it be carried to an extreme. When the horn is
very thin the heat of a shoe retained too long in contact with it
does serious mischief, and the injury known as a burnt sole has often
resulted from careless work. If a shoe, whilst being altered to fit a
foot, were cooled each time it was laid on the hoof, it would have to
be re-heated before the necessary alterations could be made and this
would cause great waste of time. The abuse of hot-fitting may do harm
without any direct burning of the sole. An ill-fitting hot shoe may be
held on the hoof until it beds itself into the horn and thus a complete
correspondence between the surface of the foot and the surface of the
shoe be effected. Such a proceeding is well described as "fitting the
foot to the shoe" and is not only destructive to the horn but damaging
to the foot by permitting an uneven shoe to look as though it were
properly fitting. When hot-fitting is used and not abused--when it is
adopted merely to indicate how and where the shoe fits, and not to make
it appear to fit--I consider it has many advantages over cold-fitting.
With some feet and some shoes it is quite possible to produce a good
fit without heating the shoe. When a shoe requires much alteration
to bring it into exact correspondence with the foot, even the most
expert farrier cannot do justice to his work with cold iron--he gets
as near to a fit as he can and when the hoof is strong little harm is
done. The best work is that which includes the greatest exactness of
fit, and uneven pressure or loose shoes result from inferior work.
A badly fitted shoe requires more nails to retain it in place, and
experience has shown that hot-fitted shoes give a smaller average of
loose or lost shoes than those cold-fitted. The slight charring of
the end of the horn fibres which results from proper hot-fitting has
never been found to do injury, and it apparently has some advantages.
One is that the surface of the hoof less readily absorbs moisture than
when not charred. Another is that the horn is softened for a time and
expanded, allowing nails to be easily driven, and then contracting and
retaining them more firmly. The objection to hot-fitting applies only
to its abuse. The advantages are greater exactness of fit, greater
security that the shoe will be firmly retained on the foot, and greater
facility in the operation of shoeing. Perhaps I ought to add that when
cold-fitting is inevitable machine-made shoes are the best, because
they are more regular in form, and more often level on the foot-surface
than hand-made shoes. Army studs on active service, and studs used in
coal mines comprise, perhaps, the only animals upon which cold-fitting
is unavoidable.

[Illustration: Fig. 58.]

=Tips= are short shoes protecting only the foremost half of the foot.
Upon grass or soft roads tips are quite sufficient to prevent undue
wear of the hoof. Even upon hard roads tips will protect the hoof in
dry weather, but in wet seasons the horn becomes softened, and then
that part coming in contact with hard road-surfaces wears rapidly and
lameness may follow. Tips require more care in use than shoes because
they protect from wear only the toe, and when retained on the foot
too long a time cause the hoof to become very disproportionately long
at the toe. In fitting a tip care must be taken to afford the horse
a level surface to bear on. The unprotected horn at the back of the
foot must take a bearing on the ground level with the ground-surface
of the tip. If there is sufficient horn on the foot this can be easily
effected by only removing the overgrown wall to just the length the
tip extends and leaving the horn behind untouched. Where there is not
sufficient superfluous horn this method cannot be used, and we apply a
tip gradually thinned off towards its hinder extremities. If a little
horn can be removed obliquely from the front half of the foot by a few
strokes of the rasp this "thinned" tip is more easily fitted so as to
get a level surface on the ground. When a horse has worn this form
for a month it is generally possible to bring a tip, of even thickness
throughout, into the same line of bearing as the horn at the heels.

[Illustration: Fig. 59.--Foot prepared for a tip.]

[Illustration: Fig. 60.--An ordinary and a "thinned" tip.]

Tips do not give a good foot-hold on grass, but they afford greater
security of tread on hard smooth roads and on ice than long shoes. The
great advantages of tips are two-fold--they are light, and they permit
the greatest freedom of movement and action in the posterior part of
the foot. In some cases of chronic foot lameness the use of tips and
regular work will effect soundness when every other method of treatment
has failed.

[Illustration: Fig. 61.--Groove for Charlier shoe formed by cutting
away strip of wall.]

[Illustration: Fig. 62.--Section of Charlier shoe on foot.]

=The Charlier System= is a method of shoeing which a few years ago took
a very prominent hold on the fancy of horse-owners. Like every other
system it has advantages and disadvantages--it has prejudiced enemies
and indiscreet friends. The principle or theory upon which it is based
may be thus stated. The lower border of the wall is, it is said, the
chief sustaining structure of the hoof, and as all that is required of
a shoe is to prevent undue wear, therefore, remove a small strip of the
lower border of the wall and substitute for it a similar sized strip
of iron, and we shall protect from wear at the same time that we leave
entirely to nature every other part of the hoof--sole, frog, and bars.
This seems eminently simple and logical, but it is easy to show that
it is more plausible than true. First, I would point out that the wall
_only_ is not the natural sustaining structure of the hoof. The wall
_and the sole at its connection with the wall is_. Next I deny that
the Charlier system does "leave entirely to nature every other part of
the hoof." In cutting away the wall from the sole to affix the shoe,
the natural function of the sole is seriously interfered with, and the
bearing on the wall which ought to be partially distributed over the
arch of the sole is limited to the wall. It is claimed that when the
foot has had time to grow the sole will be found on a level with the
shoe, and thus directly sharing in the weight-sustaining function. I
have examined many feet shod by Charlier specialists, and have never
yet seen the sole of a hind foot level with the shoe three days after
the shoeing. Only once have I seen the sole of the fore foot level
with the shoe after a week's wear. I am often apologetically told,
"Well, it is not quite in wear, but it is not an eight of an inch below
the surface of the shoe." Quite so, it is _nearly_ in wear, but if
not actually in wear what becomes of the principle? The sole is not
directly in wear and bearing is confined to the wall. As to the frog,
the Charlier affords no greater use to it than any other shoe of a
similar thickness, unless instead of being placed on sound firm horn it
be dangerously let down into the hoof so that its edge approaches very
closely to the sensitive foot. It is sometimes difficult to arrive at
the truth as to the significance of the phrase "embedding or letting
down" the shoe of the Charlier system. At one time we are assured that
"the shoe is not sunk, the sole is permitted to grow up." When this is
so, very little positive objection to the system can be taken, because
the shoe then rests at the same level on firm horn as does any other
narrow shoe; but then the frog takes no better bearing than in other
systems and the superfluous growth of horn on the sole is of no value.
When the shoe is really "let down" of course the frog does receive
increased pressure--it is forced to share with the wall the primary
function of sustaining weight instead of, as in nature, taking only
a secondary share of such action. It does this at the expense of a
shoe placed so close to the "quick" that if the upper and inner border
of iron be not bevelled off, immediate lameness results. When the
Charlier shoe was first introduced it was applied the full length of
the foot, but it was found that when thinned by wear the heels spread
and led to injury of the opposite leg or to its being trodden off.
Now the Charlier is only applied like a tip round the front portion
of the surface of the foot, and it therefore partakes of some of the
advantages I have credited to tips. It is a very light shoe and only
requires small nails to fix it securely, but as the shoe is only the
width of the wall the nails have to be driven solely in the wall,
and their position is open to the objection applying to all too fine
nailing. The disadvantages of the Charlier are its being "let down"
too near the quick, its limited bearing, and its fine nail holes; the
advantages are the lightness and the freedom given to the back of the
foot, both of which are attainable with a narrow tip not let down. One
very apparent effect resulting from the use of the Charlier system is
the alteration in the action of the horse. All knee action is lost, and
some horses go decidedly tender whilst others acquire a low shooting
stride, which is certainly not in accordance with our notions of good
free locomotion.

CHAPTER VII.

"ROUGHING."

In winter, ice, snow, and frost, render roads slippery, and it is
necessary to provide some arrangement whereby horses may have the
greatest security of foot-hold. In countries such as Canada or Russia,
where a regular winter sets in at a tolerably uniform date and
continues without intermission for some months, it is easier to adopt
a good system of "roughing" than in Great Britain. There, on a thick
layer of ice or snow, sharp projections on the shoes cut into the
surface and afford foot-hold. The edge of the projections is not soon
blunted, and when once properly placed their duration is as long as the
time desirable for retaining the shoe. Here, very different conditions
obtain. Sometimes a week or two of frost and snow may prevail, but more
frequently the spells of wintry weather are counted by days. Two or
three days of frost and then two or three days of mud and slush, to be
followed by either dry hard roads or a return of ice and snow, is our
usual winter. We require during this time to provide for occasional
days, or more rarely for weeks, of frost-bound roads. Our horses' shoes
wear about a month and then require replacing by new ones. When roads
are hard and dry we want no sharp ridges or points about our horses
shoes, and yet we must always be able at twenty-four hours notice to
supply some temporary arrangement which will ensure foot-hold.

The necessity for "roughing" and the evil effects of continuing to
work unroughed horses on slippery frost-bound roads is demonstrated in
London every winter by a very significant fact. If after three days of
ice and snow, anyone will visit a horse-slaughterers' yard, he will
find the place full of dead horses which have fallen in the streets and
suffered incurable or fatal injury. A sudden and severe attack of ice
and snow half paralyses the horse traffic of a large town for a day or
two, and many owners will sooner keep their horses in the stable than
go to the expense of having them roughed. The loss in civil life from
unpreparedness for ice and snow is very serious, but the loss which
has fallen upon military movements from similar neglect is appalling.
Napoleon's rout from Moscow in 1814, Bourbaki's flight into Switzerland
in 1871, and the Danish retreat upon Koenigsgratz in 1865 are terrible
instances of the frightful loss sustained when horses are unable to
keep on their feet at a walk, let alone drag guns and wagons over an
ice-covered surface.

[Illustration: Fig. 65.--Frost-nails, various.]

A well-managed stud of horses which is required to face all weather and
to work every day through an English winter should, from December 1st
to March 1st, be shod in such a manner as to be easily and speedily
provided with mechanism which will afford secure foot-hold. This may be
effected by the use of moveable steel "roughs" or "sharps." Of course
the cost is the argument against them, but this should be considered
in view of the probability or certainty of loss which will follow
from neglect. If we allow common humanity to animals to enter into
the consideration, economy will be served by adopting a well arranged
system of roughing. Every good horseman appreciates the enormity of
over-loading, but neglect of roughing causes just as much cruelty. A
horse that on a good road can properly draw a ton would be considered
over-loaded with two tons, and his struggles to progress would at once
attract attention. The same animal with half a ton on an ice-covered
surface would suffer more exhaustion, fatigue, and fright, and run more
risk of fatal injury than in the case of the over-loading, but his
owner who would indignantly repudiate the one condition will designedly
incur the other.

Probably this is only thoughtlessness, but it is a reflection on the
prudence of a manager, and certainly not flattering to the feelings or
intelligence of a man.

There are many ways of providing foot-hold for a horse on ice and snow.
The most simple and temporary proceeding is to use frost-nails. Fig. 65
shows various sizes and shapes of these articles.

They are not driven through the hoof like ordinary nails, but through
the shoe only, which is prepared for their reception at the time of
fitting. A shoe to carry frost-nails is fitted a little wider than
usual at the heels and has at its extremities, or more often at its
outer extremities, countersunk holes stamped and directed outwards
so that the frost-nail can be safely driven through by anyone and
its shank turned down over the shoe. There is a difficulty in firmly
securing them, they are apt to work loose and then become bent and
useless. If used on the inside heel of a shoe they constitute a danger
to the opposite leg should they bend and protrude from under the shoe.
As a temporary provision against a sudden frost or fall of snow they
are useful--but they are only a make-shift.

The more permanent and effective system of "roughing" consists in
removing the shoes and turning down a sharp chisel projection at the
heels. In very bad weather a projecting edge is also laid across the
toe of the shoe.

[Illustration: Fig. 66.--Heels of Fore and Hind Shoes, sharped.]

The diagrams show the method of "sharping" a front and hind shoe at
the heels only. The hind shoe, having calkins, is not much altered.
The smith simply converts the square calkin into a sharp-edged one.
The fore shoe having no calkins is turned down at the heels to afford
enough iron to form the 'sharp.' But this shortens the shoe, and if it
be repeated two or three times, as it often is, the bearing surface is
spoiled, and the slightest carelessness in fitting the shoe causes a
bruised heel. 'Roughing' is generally done in a hurry. A dozen horses
reach the farrier's shop at one time and all desire to return to
work with as little delay as possible. The work is perforce hurried
through, careful fitting cannot be done, and bad-footed horses suffer
accordingly. The dotted lines in Fig. 66 show the original length of
shoe, and the shortening which results from a second roughing.

All horse-owners know how many lame horses result from the repeated
roughings necessitated by a week or two of wintry weather. Some of
this is inevitable from the rush and hurry which cannot be prevented.
Valuable horses with weak feet should not be submitted to any such
risk. They should be shod with removable sharps. The mere fact of
removing a horse's shoes perhaps five or six times in a month must
injure the hoof. Add to this the shortening of the shoe, the raising
of the heel by the roughing, and the irregular bearing due to hurried
fitting and we have conditions which only the very strongest feet can
endure without serious injury.

[Illustration: Fig. 67.--Toe Sharp.]

For heavy draught horses, and for all where the roads are hilly, the
toes as well as the heels must be 'sharped' when ice and snow are
firm on the surface. Fig. 67 shows this arrangement at the toe. The
removable steel "sharps," of which I have spoken, are certainly the
least objectionable method of providing foot-hold in winter. They are
made in various sizes to suit all kinds of shoes. They vary in shape
somewhat, but their form is more a matter of fancy than utility. One in
each heel of a shoe is the usual number used but if snow and ice are
plentiful and the roads hilly two additional "sharps" may be placed at
the toe of the shoe.

[Illustration: Fig. 68.--Removable Steel Sharp.]

[Illustration: Fig. 69.--Steel Sharps, screw.]

At the time of fitting the shoes, holes are made by first punching a
round hole through the heels--and through the toe if desired--then the
hole is 'tapped' and a thread formed to fit it in the shank of the
sharp which is to fill it. If the sharps are not immediately wanted
the holes may be filled with corks to keep out the grit and dirt. When
corks are used the wear of the shoe causes a burr to form round the
edge of the hole, and before the sharp can be screwed in a "tap" must
be worked into each hole to clear the thread. One great objection to
this method is that as the shoe wears it becomes thinner, and if much
worn the shank of the "sharp" may be too long, and when screwed home
cause pressure upon the hoof and consequent lameness. To guard against
this steel "blanks" are used to preserve the holes, and when a frost
comes they are removed and the "sharps" put in.

The blanks vary in height and of course those least in height are best
for the horse's action, but they must not be allowed to get so worn
that it is impossible to remove them. These blanks are shown below.

[Illustration: Fig. 70.--Blanks, screwed.]

[Illustration: Fig. 71.--Steel Sharps and Blank, Plug shanks.]

The "tapping" and "screwing" of shoes is expensive, and in small shops
must be done by hand. In large shops a gas engine and a machine would
reduce the cost very greatly, and if the system came into general use
this method of providing against frost-bound roads could be carried
out at much less cost than now. With a view to economy and simplicity
a sharp has been invented which requires no screw. The shank may be
either round or square. A hole is punched in the heel of the shoe and
carefully gauged to the size of the shank of the "sharp." The sharp is
then put in and a tap of the hammer secures it. The difficulty is to
get the hole in the shoe and the shank of the sharp of corresponding
form and size. When this is done the sharp keeps its place and is not
difficult to remove. Too often, however, they are not uniform, and then
the sharp falls out or sometimes cannot be removed. When the holes are
drilled instead of punched the fit is more exact, but this only applies
to those with a round shank. A slight taper is given both to the hole
and the shank of the "sharp." As with the screw sharps so with these,
blanks are used to keep the holes open until the road-surface requires
the sharp.

[Illustration: Fig. 72.--Steel Taps for screwing shoes.]

No sharps should be left in shoes when the horses are stabled at
night, as serious injuries to the coronet may result from a tread by
the opposite foot. The coachman or horse-keeper must be supplied with
a spanner to remove the screws, and with a tap to clear the holes if
blanks are not used.

For roads not badly covered with snow and ice, sufficient security is
afforded by some forms of india-rubber pads, which will be described in
a future chapter.

CHAPTER VIII.

INJURIES FROM SHOEING.

Even with the most careful farrier injury may occur during shoeing,
or may arise as the result of the operation. Sometimes the foot,
from its condition or form, renders an accident possible, and it may
be so diseased, or defective, as to render shoeing with safety very
improbable. Sometimes the shoe is to blame, and sometimes the nail or
clip. A few words about each of the common injuries may be useful as
helps to their avoidance or as guides to their remedying.

=From nails= two kinds of injury may result. The most common arises
from the nail being driven too near the sensitive parts, and is known
as a _bind_. The nail does not really penetrate the sensitive foot, but
is so near as to press unduly upon it. This condition causes lameness,
which is generally not noticed till a day or two after the shoeing. It
is readily detected by the farrier on removing the shoe and trying all
the tracks of the nails in the hoof by pressure with pincers. When the
lameness is slight removal of the nail and one or two days rest are all
that is required. When the lameness is great it may be suspected that
the injury has caused the formation of matter within the hoof. This
must, of course, be allowed to escape, and the services of a veterinary
surgeon are advisable.

Any neglect in these cases, such as working the horse after lameness
has appeared, or delay in removing the offending nail, may lead to very
serious changes in the foot, or even to death of the horse.

Another injury caused by nails is from a direct puncture of the
sensitive foot. This may be slight, as in cases where the farrier in
driving the nail misdirects it and so stabs the sensitive parts, but
immediately withdraws the nail knowing what has happened. The lameness
resulting from this is usually slight. Very much more serious is the
lameness resulting from a nail which pierces the sensitive foot and
is not recognised at once by the farrier. As a rule, lameness is
immediate, and should the horse perform a journey before the nail is
removed, serious damage is certain to follow.

Want of skill in driving a nail is not always the chief cause of
"binding" or "pricking" a horse. More often than not the form and
position of the nail-holes is the primary cause, for if the nail-holes
in the shoe are too "coarse" or badly pitched it is quite impossible
to safely drive nails through them. Sometimes the nails are defective,
and this was much more common when nails were all hand-made. Bad iron
or bad workmanship led to nails splitting within the hoof, and whilst
one half came out through the wall the other portion turned in and
penetrated the sensitive foot causing a most dangerous injury. The best
brands of machine-made nails, now generally used, are remarkably free
from this defect.

No lameness resulting from injury by a nail should be neglected. If
detected and attended to at once few cases are serious. If neglected,
the very simplest may end in permanent damage to the horse. By treating
these accidents as unpardonable, horse-owners rather encourage farriers
to disguise them or to not acknowledge them. If the workman would
always be careful to search for injury and when he found it acknowledge
the accident, many simple cases would cease to develop into serious
ones. Frank acknowledgement is always best, but is less likely to take
place when it is followed by unqualified blame than when treated as an
accident which may have been accompanied by unavoidable difficulties.

=From clips= lameness may arise. A badly drawn clip is not easily laid
level and flat on the wall. When hammered down excessively it causes
pressure on the sensitive foot, and lameness. When side clips are
used--one each side of the foot--it is not difficult to cause lameness
by driving them too tightly against the wall. They then hold the hoof
as if in a vice. When shoes get loose or are partially torn off the
horse may tread on the clip, and if it be high and sharp very dangerous
wounds result.

=From the shoe=, injury results from any uneven pressure, especially
when the horny covering of the foot is weak and thin. The horn
becomes broken and split, and the bearing for a shoe is more or less
spoiled. Flat feet are liable to be bruised by the pressure of the
inner circumference of the shoe at the toe. Lameness from this cause
is easily detected by removing the shoe and testing the hoof with the
pincers. If attended to at once, and the bearing of the shoe removed
from the part little injury results. If neglected, inflammatory changes
in the sensitive parts are sure to arise.

=Corns= in horses are due to bruising of the angle of the sole by the
heel of the shoe. A wide open foot with low heels is most likely to
suffer, but any foot may be injured. The most common seat of injury is
the inner heel of a fore-foot. Even a properly fitted shoe may cause
a corn if retained too long upon a foot, as then, owing to the growth
of the hoof, its extremity is carried forward from beneath the wall
so as to press upon the sole. A short shoe, fitted too close on the
inside, is the most common cause of corn. To guard against the shoe
being trodden on by the opposite foot the inside is generally fitted
close, and to guard against being trodden on by the hind foot it is
often fitted short. Thus to prevent accidents of one kind methods are
adopted which, being a little overdone, lead to injury of another. A
not uncommon error in the preparation of the foot for shoeing may also
lead to the production of the so-called corn. If the wall on the inside
heel be lowered more than it should be the horn of the sole is left
higher than the wall, and then a level shoe presses unevenly upon the
higher part.

A corn, be it remembered, is not a tumour or a growth, it is merely
a bruise of the sensitive foot under the horn of the sole. It shows
itself by staining the horn red, just as a bruise on the human body
shows a staining of the skin above it. To "cut out a corn" with the
idea of removing it is simply an ignorant proceeding. If a corn be
slight all that is necessary is to take off the pressure of the shoe,
and this is assisted by removing a thin slice or two of horn at the
part. When the injury is very great matter may be formed under the
horn, and of course must be let out by removal of the horn over it.
Provided there is no reason to believe that matter has formed, a corn,
_i.e._, the bruised and discoloured horn, should not be dug out in
the ruthless manner so commonly adopted. Cutting away all the horn of
the sole at the heels leaves the wall without any support. When the
shoe rests upon the wall it is unable to sustain the weight without
yielding, and thus an additional cause of irritation and soreness is
manufactured. The excessive paring of corns is the chief reason of the
difficulty of getting permanently rid of them. The simplest device for
taking all pressure off a corn is to cut off an inch and a half of the
inner heel of the shoe. With the three-quarter shoe (Fig. 73) a horse
will soon go sound, and his foot will then resume its healthy state.
The saying "once a corn, always a corn" is not true, but it is true
that a bruised heel is tender and liable to bruise again, from very
slight unevenness of pressure, for at least three months. All that is
necessary is care in fitting and abstention from removal of too much
horn at the part. Of course when the degree of lameness is such as to
suggest that matter is formed the horn must be cut away so as to afford
an exit for it, but the majority of corns are detected long before the
stage of suppuration has resulted from a bruise.

[Illustration: Fig. 73.--Three-quarter Shoe.]

=A burnt Sole.= In fitting a hot shoe to a foot it sometimes happens
that the sensitive parts under the sole at the toe are injured by heat.
This is most likely to occur with a foot on which the horn is thin,
especially if it also be flat or convex. Burning the sole is an injury
which must be put down to negligence. It does not occur from the shoe
being too hot but from its being too long retained, and may be expected
when the fireman is seen holding a dull-red hot shoe on to a foot,
with a doormen assisting to "bed it in" by pressing it to the foot
with a rasp. When the heat of a shoe penetrates through the horn with
sufficient intensity to blister the sensitive parts of the foot great
pain and lameness result. In many cases separation of the sole from the
"quick" takes place, and some weeks pass before the horse can resume
work.

=Treads= are injuries to the coronet caused by the shoe of the opposite
foot, and are usually found on the front or inside of the hind feet.
The injury may take the form of a bruise and the skin remain unbroken,
it may appear as a superficial jagged wound, or it may take the form
of a tolerably clean cut, in which case, although at first bleeding is
very free, ultimate recovery is rapid. Bruises on the coronet--just
where hair and hoof meet--are always to be looked upon as serious. The
slighter cases, after a few days pain and lameness, pass away leaving
only a little line showing where the hoof has separated from the skin.
This separation is not serious unless a good deal of swelling has
accompanied it, and even then only time is required to effect a cure.
In more serious cases an extensive slough takes place, and the coronary
band which secretes the wall may be damaged. The worst cases are those
in which deep seated abscesses occur, as they often terminate in a
"quittor." The farrier should always recognise a tread as possibly
dangerous and obtain professional advice.

It is a common custom to rasp away the horn of the wall immediately
beneath any injury of the coronet, but it is a useless proceeding which
weakens the hoof and does no good to the inflamed tissues above or
beneath.

Treads are most common in horses shod with heavy shoes and high
calkins--a fact which suggests that a low square calkin and a shoe
fitted not too wide at the heels is a possible preventive.

"Cutting" or "Brushing."

By these terms is meant the injury to the inside of the fetlock joint
which results from bruising by the opposite foot. Possibly some small
proportion of such injuries are traceable to the system of shoeing, to
the form of shoe, or to the action of the horse. They are, with few
exceptions, the direct result of want of condition in the horse and
are almost confined to young horses, old weak horses, or animals that
have been submitted to some excessively long and tiring journey. The
first thing a horse-owner does when his horse "brushes" is to send
him to the farrier to have his shoes altered. In half the cases there
is nothing wrong with the shoes, and all that is required is a little
patience till the horse gains hard condition. At the commencement of
a coaching season half the horses "cut" their fetlocks, no matter how
they are shod. At the end of the season none of them touch the opposite
joint, with perhaps a few exceptions afflicted with defective formation
of limb, or constitutions that baffle all attempts at getting hard
condition. The same thing is seen in cab and omnibus stock. All the
new horses "cut" their legs for a few weeks. The old ones, with a few
exceptions, work in any form of shoe, but never touch their joints.
They "cut" when they are out of condition--when their limbs soon tire;
but they never "cut" when they are in condition--when they have firm
control of the action of their limbs. There are, however, a few horses
that are always a source of trouble, and there are conditions of
shoeing which assist or prevent the injury. The hind legs are the most
frequently affected and this because of the calkins. Many horses will
cease "cutting" at once if the calkins of the shoes be removed and a
level shoe adopted. There are certain forms of shoe which are supposed
to be specially suitable as preventives. A great favourite is the
"knocked-up-shoe"--_i.e._, a shoe with no nails on the inside except at
the toe, and a skate-shaped inner branch.

[Illustration: Fig. 74.--"Knocked-up" Shoes--with and without an inner
Calkin.]

These shoes are fitted not only close to the inner border of the wall
but within it, and the horn at the toe is then rasped off level with
the shoe. Whether they are of any use is a question, but there is no
question of the harm they do to the foot. Some farriers are partial
to a three-quarter-shoe--one from which a couple of inches of the
inside heel has been removed. Some thicken the outside toe, some the
inside toe. Some raise one heel, some the other, and some profess
to have a principle of fitting the shoe based upon the formation of
the horse's limb and the peculiarity of his action. If in practice
success attended these methods I should advise their adoption, but my
experience is that numerous farriers obtain a special name for shoeing
horses that "cut," when their methods, applied to quite similar cases,
are as antagonistic as the poles. A light shoe without calkins has at
any rate negative properties--it will not assist the horse to injure
himself. For all the other forms and shapes I have a profound contempt,
but as people will have changes, and as the most marked departure from
the ordinary seems to give the greatest satisfaction, it is perhaps
"good business" to supply what is appreciated.

The two great cures for "cutting" are--regular work and good old beans.
When a man drives a horse forty miles in a day at a fast pace he, of
course, blames the farrier for all damage to the fetlocks. He is merely
illogical.

[Illustration: Fig. 75.--Toe of Hind Shoe showing the edge which cuts
the Front Foot.]

Over-reaching.

This is an injury to the heel--generally the inner--of a front foot.
The heel is struck by the inner border of the toe of the hind shoe.
Over-reach occurs at a gallop in this country, but is seen in America
as the result of a mis-step in the fast trotters. An over-reach can
only occur when the fore foot is raised from the ground and the hind
foot reaches right into the hollow of the fore foot. When the fore and
hind feet in this position separate the inner border of the toe of the
hind shoe catches the heel of the fore foot and cuts off a slice. This
cut portion often hangs as a flap, and when it does the attachment
is always at the back, showing that the injury was not from behind
forwards as it would be if caused by a direct blow, but from before
backwards--in other words by a dragging action of the hind foot as it
leaves the front one. An over-reach then may result either from the
fore limb being insufficiently extended, or from the hind limb being
over extended.

The prevention of this injury is effected by rounding off the inside
edge of the hind shoe as shown below.

[Illustration: Fig. 76.--Toe of Hind Shoe showing rounded inside
border.]

Speedy-cut.

This is an injury inflicted on the inner surface of the lower part of
the knee joint by a blow from the toe of the shoe of the opposite foot.
It occurs at a trot, and very seldom except when a horse is tired or
over-paced. A horse that has once "speedy-cut" is apt to do so again
and it may cause him to fall. Such horses should be shod "close" on
the inside, and care should be taken that the heels of the foot which
strikes should be kept low. In some cases a three-quarter shoe (see
Fig. 73) on the offending foot prevents injury.

"Forging" or "Clacking."

This is not an injury but an annoyance. It is the noise made by the
striking of the hind shoe against the front as the horse is trotting.
Horses "forge" when young and green, when out of condition or tired.
As a rule, a horse that makes this noise is a slovenly goer, and will
cease to annoy when he gets strength and goes up to his bit. Shoeing
makes a difference, and in some cases at once stops it. The part of the
front shoe struck is the inner border round the toe. (Fig. 77). The
part of the hind shoe that strikes is the outer border at the inside
and outside toe. (Fig. 78).

[Illustration: Fig. 77.--Toe of Fore Shoe. The arrows mark the place
struck in "forging."]

[Illustration: Fig. 78.--Toe of Hind Shoe showing the edge which
strikes the Fore Shoe.]

[Illustration: Fig. 79.--Toe of Fore Shoe with inner border bevelled
off.]

To alter the fore shoe, round off the inner border; or use a shoe with
no inner border such as the concave hunting shoe To alter the toe of
the hind shoe is useless, but by using a level shoe without calkins
some advantage is gained. A so-called "diamond-toed" shoe has been
recommended. It is not advisable as it does no good except by causing
its point to strike the sole of the front foot. If by such a dodge the
sound is got rid of it is only by running the risk of injuring the
foot.

CHAPTER IX.

SHOEING BAD FEET.

Any average farrier can shoe without immediate harm a good well-formed
foot that has a thick covering of horn, but when the horn is deficient
in quantity or quality injury soon takes place if a badly fitted
shoe be applied. There are feet which from disease or accident or
bad shoeing have become, more or less, permanently damaged. Some are
seriously altered in shape. Some are protected only by an unhealthy
horn, and some show definite changes which cause weakness at a special
part. These are the feet which really test the art of the farrier, for
he must know just what to do and what not to do, and must possess the
skill to practice what he knows.

=Flat Feet.= Some horses are born with flat feet, others acquire them
as the result of disease. Too often the flat sole has another defect
accompanying it--low weak heels. Such feet are best shod with a seated
shoe so as to avoid any uneven pressure on the sole, and the shoes
should always be fitted a little longer than the bearing-surface of the
foot, so as to avoid any risk of producing a bruise at the heel--in
other words, of causing a corn. The seated shoe is not advisable on a
hunter. The concave shoe used for hunters has many distinct advantages
and only one disadvantage for a flat foot, viz, that it has a wide flat
foot-surface. It may cause an uneven pressure at the toe on a flat
sole, but this is easily avoided by not making it too wide; perhaps the
very worst thing to do with a flat foot is to try and make it look less
flat by paring it down. The thinner the horn the greater the chance
of injury to the sensitive parts under it, and every injury tends to
make the sole weaker. Leaving the sole strong and thick, whilst fitting
the shoe to avoid uneven pressure, is the principle of shoeing to be
adopted with flat feet.

=Convex Soles.= The sole of the foot should be concave, but as the
result of disease many feet become convex. This bulging or "dropping"
of the sole varies in degree from a little more than flat to an inch or
so below the level of the wall. When the under-surface of a horse's
foot resembles in form the outside of a saucer, fitting a shoe becomes
a work of art. Very often the wall is brittle and broken away and
it is most difficult to find sufficient bearing-surface on the foot
for a shoe. Many of these feet may be safely shod with a narrow shoe
that rests only on the wall and the intermediate horn between the
wall and sole. Such a shoe may, according to the size of the foot, be
five-eighths or even three-quarters of an inch wide. Its thickness
is to be such as will prevent the sole taking any direct bearing on
the ground, and sometimes a shoe of this form is much thicker than
it is wide. The advantage of this shoe is that it is so narrow that
any bearing on the sole is avoided. The disadvantage is that on rough
roads the sole may be bruised by the flint or granite stones. When the
horn of a "dropped" sole is very thin, or when the horse has to work
on roads covered with sharp loose stones, some cover for the sole is
necessary and the narrow shoe is not practicable. To provide cover
for the sole, the web of the shoe has to be wide, and, therefore, the
foot-surface of the shoe must be seated out so as to avoid contact
with the sole. Too often the seating is continued from the inner
to the outer border of a shoe, so that no level bearing-surface is
provided for the wall to rest on. This kind of shoe is like the hollow
of a saucer, and when applied to a foot is certain to cause lameness
soon or later. Each time the horse rests his weight on it the hoof
is compressed by the inclined surface of the shoe, which instead of
providing a firm bearing-surface affords only an ingenious instrument
of torture.

[Illustration: Fig. 80.

Improper bearing surface.

A level bearing surface.]

In even the worst of these deformed feet some good sound horn is to be
found at the heels, where an inch or sometimes two can be utilised for
level bearing. No matter how much seating is required at the toe and
quarters, the heel of the shoe may always be made level.

It cannot be too strongly urged that in the preparation of feet with
bulging soles no horn is to be removed from the sole. The toe is to be
shortened, the heels lowered proportionately, and the bearing-surface
of the wall made level with a rasp. At no place must the shoe rest on
the sole. In nearly every case the toe is left too long and the bearing
taken upon it by the shoe only increases the deformity. In many feet a
large slice might be sawn off the toe with advantage, as the sensitive
foot is separated from the wall by a mass of diseased horn which
presses the wall at the toe forward. (Fig. 81).

[Illustration: Fig 81.

Deformity resulting from Laminitis.

Section showing how front of wall is separated from sensitive laminæ.]

=Sandcracks.= This is the name given to cracks in the wall which
commence at the coronet and extend downwards. From their position
at the toe, or at the side of the hoof, they are sometimes called
respectively "toe-cracks" and "quarter-cracks." The crack may be very
slight and may exist without causing lameness. It may appear suddenly,
accompanied by great lameness and by the issue of blood from between
the edges of the divided wall. These are grave cases which require
surgical attendance. Sandcracks are most commonly seen in dry brittle
feet, and the horses most subject to them are those employed in heavy
draught work. Railway shunt-horses and omnibus horses are very liable
to be troubled with sandcracks in the toe of the hind feet.

In shoeing for this defect there are two things to avoid, (_a_) not to
place any direct pressure on the part; (_b_) not to fit a shoe which
will tend to force the crack open. Following these lines it is well
not to put a clip exactly over a crack. If at the toe place a clip
each side of the crack, and never use calkins or high heels which
throw the weight forward. If at the quarter avoid a spring-heeled shoe
which permits the downward movement of the foot behind the crack and
so forces it open. In all cases, after fitting the shoe level to the
foot, remove a little more horn just below the crack so as to relieve
the direct bearing on the part. (Fig. 82).

[Illustration: Fig. 82.

=A=--Horn removed to prevent pressure.

Bearing relieved at wrong place by "springing" the heel.]

In the case of crack extending the whole space of the wall some
provision should always be made to keep it from opening, because every
step of the horse, especially when drawing a load, causes an outward
pressure at the coronet. This pressure forces the hoof apart and the
injury caused does not cease with the pain and lameness which follow,
and which may be temporary. Doubtless the original cause of a sandcrack
is some morbid condition of the coronary band--the band from which the
wall grows. The sensitive laminæ are at first not affected further than
by the inflammation consequent upon the direct tearing which occurs
when the crack takes place. The continued irritation, kept up by a
persistent fissure in the horn covering the laminæ, soon causes other
serious changes which tend to make the sandcrack a permanent disease.
Thus even the smallest crack should be attended to and measures adopted
to prevent its enlargement or, when extensive, to limit all opening and
shutting movement of the hoof.

[Illustration: Fig. 83.--French Clips in Position.]

This is sometimes attempted by a simple leather strap tightly applied,
or by binding the foot with string or tape. Tape is less liable to
slip than string. When the hoof is sufficiently thick two nails may
be driven in opposite directions transversely through the crack and
clinched; or French sandcrack-clips (Fig. 83) may be used which are
easily applied. The instruments necessary are shown below (Fig. 84).
The iron (_b_) is made red-hot and pressed on the hoof over the crack
so as to burn a groove each side of it. Into these grooves the clip
(_a_) is put and the pincers (_c_) are then used to compress the clip
firmly into its place. There is a strain upon the clips, and sometimes
one breaks. It is therefore necessary always to use two, and for an
extensive crack three may be employed.

[Illustration: Fig. 84.]

All these appliances tend to keep the lips of the crack from
separating, but they do not prevent the edges of a deep wide crack from
being forced together and thus pinching the sensitive parts. To provide
against this injury a slip of hard wood may be fitted into the crack,
and then the nails or clips may be more safely drawn tight without fear
of injury, and with a better chance of preventing any movement in the
edges of the crack. To insert the wood, the crack is converted into a
groove nearly as deep as the wall, about three-eights of an inch wide,
with straight sides, or better still, with a little greater width at
the bottom than at the surface. Into such a groove a piece of wood
formed to fit it is gently driven from below and rasped off to fit
exactly. Or, softened gutta-percha may be pressed firmly into the space
and levelled off when cold.

To "cut out" a sandcrack except for the purpose of refilling it is bad
practice as it favours movement and helps to make the defect permanent.
To rasp away the horn so that only a thin layer is left is also
injurious. No horn should be removed except for the fitting of a plug
as above described or, under veterinary direction, for the purpose of
giving vent to matter which has formed within the hoof.

In many European countries a shoe is used for toe-cracks which has two
clips drawn on the inside border of the shoe at the heels. These clips
catch the bars of the hoof and prevent the heels of the foot closing
in. The idea is that when the wall at the heels contracts, there is a
tendency for the wall at the toe, if separated by a crack, to open.
Fig. 85 shows the position of the clips which must be carefully fitted
so as to rest on the inside of the bars. Mr. Willis, V.S., has tried
these shoes and speaks well of their utility.

[Illustration: Fig. 85.--Shoe with Heel Clips for Sandcrack.]

When the crack is in the quarters of the foot, it is not the tendency
to expansion of the hoof that has to be guarded against. It is the
downward motion of the heels that forces open a crack in this position.
The farrier provides against this by taking care to have a firm bearing
of the shoe on the hoof behind the crack as shown in A figure 82.

=Contracted Feet.= Some diseases of the foot lead to contraction of
the hoof, which is most noticeable round the coronet and at the heels.
Any long continued lameness which prevents the horse placing the usual
weight on the foot may be accompanied by contraction. Constant cutting
away of the bars and paring the frog so that it takes no contact with
the ground also leads to shrinking in of the heels. By lowering the
heels and letting the frog alone many feet will in time widen out to
their proper size, but no system of shoeing is so good for contracted
feet as the use of tips, which leave the whole back part of the hoof to
take direct bearing on the ground.

Many shoes have been invented for forcing open the heels of contracted
feet. Some have had a hinge at the toe and a movable screw at the
heel. Some have had the bearing-surface at the heels made with a slope
outwards, (See Fig. 53, page 74) so that the weight of the horse should
constantly tend to force the heels apart. There is no necessity for any
of these contrivances. A properly fitted tip (See page 78) will permit
the hoof gradually to expand to its healthy size and form.

=Seedy-toe.= This is a condition of the wall usually found at the toe
but not uncommon at the quarters. It is not common in hind feet but
occurs sometimes. When the shoe is removed a separation is noticed
between the sole and the wall, and this separation may extend up the
wall nearly to the coronet. As a rule the space so formed is a narrow
one, but it may be wide enough to admit three fingers of a man's hand.
Probably all seedy toes result from some injury or disease of the
coronary band from which the wall grows, and the first appearance is
not a cavity but a changed and softened horn, which may be dry and
crumbly, or moist and cheesy. The diseased horn may be scraped out
and the cavity filled with tar and tow. The wall bounding the cavity
should be relieved of all pressure on the shoe, and if a radical cure
be desired all the unattached wall should be cut away. This, however,
should be done under veterinary guidance.

=Turning in of the Wall.= By this expression, I mean those cases of
weak low-heels in which the border of the wall turns inward. Such a
form of horn offers no suitable bearing for a shoe, and if submitted to
pressure by a shoe gets worse. Too often this condition is treated by
paring away the sole within, which increases the deformity. The sole
should not be cut but be left as strong as possible. The curled-in
border of the wall should be cut down and all bearing taken off the
shoe. In one or two shoeings the wall will resume its proper form. When
both heels are so affected, and the horse has to remain at work, only
one heel must be treated at a time. The extreme point of the heel is
never affected, and affords a point for bearing when the border of wall
in front of it is cut away so as not to touch the shoe.

CHAPTER X.

LEATHER AND RUBBER PADS.

In the days when farriers were driven by theoretical teachers to pare
out the soles and otherwise rob the foot of its natural covering
of horn, artificial protection had frequently to be given to the
foot. A horse with a thin sole could not travel over rough roads,
on which sharp loose stones were plentiful, without great risk of
injury; consequently in those times plates of leather were often used
to protect the foot. When a horse went "a little short" his owner
not unnaturally concluded that he had bruised his foot and that the
protection of a leather sole would be beneficial. In many cases the
defective action was due to other cause than bruising, but still the
leather was adopted, and it soon became an accepted theory that leather
soles modified concussion and protected the foot from jar. This is
more than doubtful, and I hold a very firm opinion that a plate of
leather between the shoe and the foot has no such effect, whilst it
interferes with the exactness of fit of the shoe. "Leathers" are useful
on weak feet to protect a thin or defective sole from injury. When the
under surface of a foot has been bruised, cut through, or when it is
diseased, leather offers a useful protection, but when the sole is firm
and sound it is quite unnecessary.

To apply leather properly, a square piece fully the size of the shoe
is taken. A portion is then cut out where the clip has to fit and all
protruding parts cut away level with the border of the shoe. If applied
without more precautions, an open space would be left between leather
and sole into which mud and grit would find their way and the leather
would soon be cut through by resting on the irregular surface of the
frog. To prevent this mischief the under surface of the foot is made
level before the shoe is applied. The leveling is managed by spreading
a paste of tar and oatmeal over the sole, and filling up the space
at the sides of the frog with tow. Then the shoe with the leather is
nailed on in the usual manner.

The belief in leather as an anti-concussive appliance has led to the
use of what are called "ring-leathers." These are not plates covering
the whole under surface of the foot but narrow bands fixed between shoe
and hoof. They are absolutely useless, in fact their only possible
effect is to spoil the fit of the shoe. Plates of india-rubber have
been tried between the shoe and the foot as preventives of concussion.
They invariably fail by reason of their effect upon the shoe. At each
step when the weight of the horse comes on the foot the elastic rubber
yields, the shoe is pressed closer to the foot, the nails are loosened,
and when the foot is raised the rubber rebounds. The shoe soon becomes
so loose that it is cast or torn off. Nothing elastic should be placed
between shoe and foot. When an elastic or spring is applied it must be
between the shoe and the ground.

Various arrangements have been adopted to supply the horse's foot
with some provision against concussion. Injured and diseased feet may
no doubt be benefitted by some elastic appliance which secures them
from the jar of contact on a hard road. They may be protected against
direct bruise. The healthy foot requires no such protection. Nature
has covered it with a thick layer of horn and has provided against
concussion by quite other means--by the co-ordinate action of muscles,
by the oblique position of the pastern and by the construction of the
back part of the foot.

Quite apart from any attempt to prevent concussion a valuable use has
been found for india-rubber pads in connection with horse-shoeing.
The improvement in modern road-surfaces has been accompanied by an
increased facility for slipping, and it has been found that no material
gives such security of foot-hold on smooth surfaces as india-rubber.

The earliest of these contrivances with which I am acquainted was
formed so as to leave the frog uncovered whilst a bearing of rubber was
given all round the inner circumference of the shoe. This pad had a
wide flat border which fitted under the shoe, with which it was nailed
on to the foot. Its great objection was that it could not be nicely
fitted on many feet without first cutting away the bars.

Then we had rubber pads which were not nailed on with the shoe, but
which fitted into the shoe and were removed at will. The objection to
these was that they could only be used with a seated shoe and could not
be applied with a narrow shoe or one possessing a flat foot-surface.

The next form to appear was a leather sole on which an artificial
frog was fixed. Great difficulty was at first experienced in fixing
this frog so that it remained firm. The difficulty has not yet been
surmounted by all makers, but Mr. G. Urquhart, of London, makes a
most reliable article. These "frog-pads" certainly give a very good
foot-hold on all kinds of paved streets.

[Illustration: Fig. 86.--Frog-pad.]

A pad of very elegant appearance is "Sheather's Pneumatic." It is not
solid like the ordinary frog-pad but hollow and is compressed at each
step but immediately resumes its prominent form on being relieved of
pressure.

[Illustration: Fig. 87.--Sheather's Pad.]

One of the simplest anti-slipping pads is "Balls & Keep's Wedge-pad."
It possesses one advantage in not covering up the whole under-surface
of the foot. When properly fitted it is firmly retained and does its
work, but a careless farrier may so apply it that it shifts on the
foot. To fit it exactly the wall of the back part of the foot must be
lowered more than that in front, so that shoe, foot and pad may all be
closely adjusted.

[Illustration: Fig. 88.--Wedge-Pad.]

[Illustration: Fig. 89.--Pad with Shoe attached.]

What is called the "Bar-pad" is a leather plate on which an
india-rubber pad occupies the whole of the back portion and it is fixed
to the foot with a short shoe. This pad is not only an anti-slipping
agent, it is anti-concussive, and for some diseases and some injuries
of the heels is a most valuable appliance. For long-standing "corns,"
for cases of chronic laminitis, and for horses that markedly "go
on their heels" the bar-pad is without doubt the most efficient
arrangement yet invented. The best are made by Mr. Urquhart.

[Illustration: Fig. 90.--Bar-pad with Shoe.]

[Illustration: Fig. 91.--Without Shoe.]

All these pads increase the cost of shoeing but what they save, by
preventing falls and injuries to the horse and fear and anxiety to the
driver, far more than balances the account in their favour. The cost
however is an item, and inventors have turned their attention to the
production of some other methods of applying rubber in connection with
the shoe for the prevention of slipping.

Shoes have been manufactured into which cavities of different forms and
sizes have been made. These are filled by correspondingly shaped pieces
of rubber. The cavity must be so formed as to retain the rubber and
this renders the manufacture very difficult except by the employment of
malleable cast iron shoes. This is a great disadvantage.

Another plan is to make from rolled bar iron, a hollow shoe, section
of which would be U-shaped but level to the foot. Into the groove so
formed a thick cord of rubber is placed after the shoe is nailed on
the foot. This wears well and affords good foot-hold but it entails
the serious objection that the nails are difficult to drive and far
from being so safe as in the ordinary shoe. If rubber is ever to be
available in a grooved shoe it should be designed so that the nails and
nail holes are not interfered with.

CHAPTER XI.

SHOEING COMPETITIONS.

The Agricultural Societies that have made Horse-shoeing Competitions a
feature of their Annual Shows have distinctly done good to the art. In
those districts which have had the benefit of these competitions for
many years past, horse-shoeing is best done. In those districts where
no competitions have been held shoeing is generally badly done. When
the farrier takes a pride in his work he is more careful with details.
Provided proper principles are adopted, no calling is more dependent
upon care in details for the best results than that of the farrier.
Competitions stimulate emulation amongst men. Public appreciation, as
displayed by the prominence given to the art by the Show authorities
and by the admiring crowd that generally assembles to see the men at
work, encourages a feeling of responsibility and gratifies the natural
and honest pride of the workman. Very few trades have suffered more
from public neglect and indifference than that of the farrier.

The success of a shoeing competition depends almost entirely upon the
secretary of a show, unless that officer has amongst his stewards an
energetic horseman who has grasped the importance of good shoeing and
who possesses some organising powers. In this connection I may perhaps
offer a word of acknowledgement for the work done by Mr. Clay, to whose
energy and skill the Royal Agricultural Society has for many years been
indebted for the success of its valuable annual shoeing competition.

All the arrangements for the competition must be completed before the
work is commenced, and upon their perfection depends the success of
the whole thing. There should, if possible, be two classes--one for
heavy horses and one for light horses. At large competitions there
should also be a champion class. There are farriers who travel from
show to show and generally appear in the prize list. This handicaps
the local men, and is not encouraging to those who have not quite
risen to front rank. The object of the competition is to improve the
work of the district, and it is quite a question whether the rules
should not exclude men who have taken, say, two first prizes at any
large competition. The only argument in favour of letting the well
known smith who has taken many prizes enter a competition is that his
work may be seen, examined and imitated. By confining prize winners to
the champion class this good would be attained; at the same time more
encouragement would be given to local men.

The necessities for a competition include anvils, fires, tools, iron
and horses.

For every five men there should be one anvil with its accompanying vice
and forge. The anvil should be so placed that the sun is not full on
the face of the workman. The exact relative position of anvil, vice
and forge should be entrusted to a practical farrier, and the whole
placed the night before they are wanted. Coal, nails and iron should
also be provided. If competitors are allowed to bring their own iron or
nails some poor man may be placed at a disadvantage, and the habitual
competitor, versed in every detail, is given an advantage. Each man
should bring all smaller tools he may want. In broken weather a canvas
roof should be supplied both for horses and workmen. At all times a
temporary wooden floor should be put down for the horses to stand upon.
This should be a little longer than the line of anvils so that each man
has his horse opposite his anvil. It should be at least twelve feet
deep so that there is room enough behind and in front of the horses for
men to pass. On the side farthest from the anvils a firm rail must be
fixed to which the horses' halters may be tied, and outside of this--at
least six feet distant--should be another line of post and rails to
keep back spectators.

Horses have to be borrowed or hired, and one horse is sufficient for
two competitors. Care should be taken not to have any horse with
unusually bad feet. The most suitable horses are those with overgrown
hoofs. Under no circumstances should a vicious or very fidgety horse be
selected.

When time is not an object, the best test of a workman is to require
him to make a fore and hind shoe and put them on the horse. At a
one-day show, or at a competition when the entries are large, it is
sufficient to require the making of a fore and hind shoe and the
fitting and nailing on of the front one. A reasonable time should be
fixed, and undue haste should be deprecated.

There should always be two judges, who should be supplied with books in
which each division of the operation of shoeing should be separately
marked. There are only three important divisions of the subject: (1)
Preparation of the Foot, (2) Making the Shoes, and (3) Fitting and
nailing on.

Sometimes these operations are marked separately for fore and hind
feet. I consider this quite unnecessary. There is not sufficient
difference either in principle or detail to require each foot to be
specially marked. The judge of course notes every thing in his mind,
and it is sufficient for him to estimate and mark the value of the
work under the three different operations. The great fault I find
with most competitions is that "the preparation" of the foot for the
shoe is not more strictly defined. The competitors are permitted to
mix up the "preparation" and the "fitting." Some of them do nothing
to the foot until they commence to fit the shoe. This is wrong, and
every foot should be properly prepared--the bearing-surface formed
and the proportions of the hoof attended to--before the fitting is
attempted. A rule to this effect should be added to the conditions in
the schedule of the competition. Each judge may perhaps be permitted
to fix his own standard of marking but a uniform system would be
useful for comparison. If the maximum be indicated by too small a
figure difficulty often arises in exactly determining the merits of
men who have come out equal in the totals, and there is too often,
in a large class, a number whose marks are about equal. The three
operations--preparing the foot, making the shoe, fitting and nailing
on--are about equal in value. A maximum of five points in each is too
small a number to make distinctive marking easy, but there is nothing
gained by adopting a higher maximum than ten. A marking sheet for the
judges of a shoeing-competition may be something in this form:

The stewards should see that each competitor has a number, and that the
same number is attached to the side of the horse on which he works. The
steward also should take the time at which each batch of competitors
commence and see that none exceed it.

Excessive rasping of shoes should be prohibited, and the men should
see the sizes and kinds of nails provided so that they may make their
"fuller" and nail holes accordingly.

Shoeing competitions are almost entirely confined to country districts.
It is a great pity that they are not attempted in large towns. The only
difficulty is the expense. It would well repay large horse-owners to
subscribe and support this method of improving the art.

In conclusion I must say that the best of all ways to improve the art
is by giving practical instruction at the anvil. A few lessons from a
competent practical teacher are worth more than all books or lectures,
as the work has then to be done, errors are pointed out and corrected,
and reasons given for each step as it is attempted.

The Berkshire County Council has adopted a travelling forge--the
suggestion of Mr. Albert Wheatley, V.S., of Reading--which is
accompanied by an instructor and passes from town to town and village
to village. In this way is supplied the tuition which used to be
obtained by apprenticeship to a good workman. Other County Councils
should adopt this method.

Gold Medal
Mid-Winter Exhibition,
San Francisco, 1894.

The Capewell Nails are:--
"The Best Driving Nails,"
"The Best Nails to Hold," and
"The Safest Nails to Use."

They never split in driving,

They never buckle in the hardest hoof.

They are flexible to clinch, and the clinch holds against any strain
in service.

Their perfect points make a clean cut hole in the most brittle hoof.

They are absolutely uniform in length, breadth, and thickness.

=They are manufactured in London from the best Swedish Iron=,
the quality of which is improved in compactness,
tenacity, and uniformity of temper by the "Capewell
Process."

As demonstrated by actual mechanical tests at Chicago, the tensile
strength of the Capewell is greater than that of any other nail made.
Thus it is that the Capewell nails never break under the heads but hold
the shoe until it is worn out.

On Sale by all Iron Merchants, Ironmongers,
and Dealers.
