PREFACE.
In preparing the following lessons, in answer to the demand of the public
school teacher for such assistance, the aim has been to present them in
such a manner that both teacher and pupil may, through the understanding
and acceptance of the steps involved, become expert in the development
and delineation of _original_ maps showing surface structure in relief.
To this end, suggestions vital to the success of the would-be mapmaker
will be found in the Introduction.
In Part II. it is aimed to show that, with a clear mental image of
surface forms and areas, the expression of the same will be a simple and
easy matter, and a valuable preparation for the mapping of large areas or
continents.
For the illustrations a medium has been used, which, in many respects,
closely resembles in its results on paper the texture of chalk on the
blackboard.
The author desires to acknowledge her indebtedness to Francis W. Parker,
the head of the Chicago Institute, late Principal of the Chicago City
Normal School, for help derived from the study of his works, and for
the rare educational privilege enjoyed while working as a member of his
Faculty. Especially were the discussions under his leadership, at the
ever-to-be-remembered weekly meetings, a continual source of inspiration.
Under the new light thrown upon the subject of geography, as presented by
Colonel Parker, the impulse was first received which afterward bore fruit
in the development of a new method of map drawing; a method which it was
desired should be an adequate expression of the solidity and continuity
of the continental land mass.
The necessity for such a map Colonel Parker had himself realized for
years and had sought its delineation. With a desire to meet the pupil’s
needs in this respect, upon further study of structural geography the
idea was conceived of drawing maps which would show mass without outline,
and which would also represent relief.
This method of map drawing was called “Chalk Modeling,” and from the
first crude effort in this direction by the author, in the year 1891, at
the Cook County Normal School, the “Chalk Modeled Map” passed through
many stages of development until it reached its present form.
Thus to Colonel Parker himself is primarily due whatever of educational
value has resulted from the invention of the author or development by
others of what is called “The Chalk Modeled Map.”
Acknowledgments are also due Miss Louise Barwick, for the zeal displayed
in forwarding the development and delineation of the Maps of the
Continents, and for valuable assistance rendered in the drawing of the
same, as illustrations for this work.

INTRODUCTION.
[Illustration]
NECESSITY FOR THE STUDY OF STRUCTURAL GEOGRAPHY PREPARATORY TO THE
DRAWING OF MAPS.
The fundamental object in the study of Geography, as we understand it,
is to acquire mental images of the present appearance of the earth’s
surface; its structure, the rocky material of which it is composed, and
the causes and effects of its changes, as a preparation for the home of
organic life.
It is a study of the earth as a material basis for the evolution of man,
and the development of civilization. It leads up to a search for the laws
and workings of the creative forces—forces relating to our planet and to
the sun, the central source of light and heat.
This study has a different meaning to different persons. To one it means
the study of all that lies between the covers of a book, or memorizing
other people’s sayings. To another it means “Connected information
regarding the condition of man’s life on this planet”—again “Geography
is a description of the earth’s surface, or anything that affects or is
affected by it.” A more common definition is, “Geography is a description
of the earth’s surface and its inhabitants.”
An ability to recognize in present environment that which leads to
an understanding of geographical conditions in general, is much to be
desired and is the aim of the teacher of the present day. Geologists
tell us that the same processes are going on now that have ever been in
operation, in the fitting of the earth for the habitation of man. That
these changes are taking place is implied in the very fact that we are
studying the earth’s present appearance.
The study of the history of these changes, and of the nature of the
earthy material as shown in rock and soil, and in vegetation, and of the
influence of heat, light, air and moisture, means the study of all the
natural sciences; not as special isolated studies, but bound together in
one great whole. So closely are they related, merging into and impinging
upon each other as they do, that there seems to be no place or line of
separation between them.
The larger part of the surface of the earth (nearly three-fourths) is
covered with water, and the action of this mighty agent, under the
influence of that great dynamic force and life-giving energy, heat, opens
an immense field for investigation.
These combined influences constitute the study of the environment of all
organic life; and knowing these in a given case, we get an approximate
idea of the stage of development. The development of man, the highest
type of organic life, depends largely upon structural, climatic,
vegetable and animal environment.
To know these is to understand his habits of life, his reasons for choice
of homes, and to judge of his probable advancement in civilization.
The powerful influence which the physical features of the earth’s
surface have exerted in shaping the current of historical events, can
hardly be realized, until thoughtful investigation of the subject
has been made. The knowledge of geographical conditions, as climate,
mountains, valleys, rivers and seas, with vegetable and animal life gives
us the theatre of action for events in history.
As the mere existence of mountain range, desert, sea or river, may
be essentially the influence which has led to the growth or downfall
of empires, it is clearly seen that a sound knowledge of structural
geography is absolutely necessary for all intelligent study of history;
no general relation of important occurrences can be traced without it.
Nearly, if not equally necessary is it in the study of literature. In
order to properly appreciate the works of our best writers, both of prose
and poetry, an acquaintance with nature, a scientific and geographical
knowledge, local and general, is very essential. It forms a basis for
the correct understanding of books, since the best writers and thinkers
of all ages have been students of nature. Their writings are filled
with lessons and illustrations, as well as generalizations drawn from
close observations of her methods. If, then, a knowledge of structural
geography is requisite to the true understanding of man’s relation to
man and the world around him, it becomes important that the subject be
presented in such a manner as to attract and hold the interest of the
pupil; and properly presented there can be nothing more interesting than
the study of his immediate environment—that which touches him in his
every day experience.
This study of his immediate environment is essential to the forming of
mental images of areas and surface forms outside and beyond his sense
grasp and to a comprehension of the structure and surface contour of the
world at large: such mental images being fundamentally a necessity to the
delineation of adequate structural maps of the whole or any part of the
earth’s surface.
NECESSITY FOR FIELD LESSONS AND IMPORTANCE OF FORMING, IN CONNECTION WITH
THEM, A HABIT OF MODELING, PAINTING AND DRAWING.
The study of geography, which in the past consisted mainly in the
memorizing of meaningless names with little or no exercise of the
reasoning faculties, or opportunities for making generalizations through
acts of comparison and inference, has been superseded by instruction of a
more rational order.
We have learned that to memorize names and locations of mountains, rivers
and lakes, without seeing their relation to a whole, or to make only
superficial observations of extended areas of land, results merely in
indefinite mental impressions, leaving out the very basis of all concise
and clearly defined geographical knowledge.
To the end that definite mental images may be acquired, field excursions
under the direction of competent leaders are now advocated, and when
entered upon with an intelligent purpose are held to be indispensable
factors in the correct study of geography.
[Illustration: SECTION OF STREAM SHOWING RAPIDS.]
Under these conditions (the intelligent purpose and the competent
leader), the pupil who visits a lake is likely to have a more adequate
mental image of old ocean, than one who has never seen a lake or other
large body of water. One who has seen low hills with their out-cropping
rock, and the action of small streams upon them, will have a better idea
of what mountains and rivers may be.
In the new education the pupils are thus in the field lesson brought face
to face with nature. Through these lessons the powers of the imagination
are quickened and strengthened by the continual observation of surface
forms, the true basis for all attempts to image the structure of the
earth.
Inferences are made at every step of the way as to the history of the
physical features observed, and the nature of the forces that have acted
upon them to shape and distribute. Areas and forms of land are constantly
being compared as to shape, size, width, length and height, and simple
generalizations, formed from direct observations, are combined with other
generalizations, to form those that are higher or more comprehensive.
This is but a brief suggestion of the part the field lesson bears to
education in general.
In the particular study of geography it must be borne in mind that no
essential knowledge can be gained except through close observation of the
earth’s surface forms. As the true teacher of science in his classes in
botany or zoology leads his pupils to an individual study of plants and
animals, and also to a study of these in their surroundings, their social
relations, so also the student of geography goes directly to nature for
all fundamental knowledge pertaining to the subject.
Field lessons, though conducted mainly as contributing to the student’s
fund of knowledge, are also a source of pleasure, and may be made the
foundation of a more healthful love for and delightful companionship
with nature. They are not alone a mine of knowledge but also a perfect
well-spring of inspiration.
In every stream, plain and valley, new beauties of form and color are
continually presenting themselves. Varying tints of landscape vistas,
drifting cloud masses, softly rounding hills, majestic mountain forms,
the play of sunlight and shadow; all make subtle appeal. Entering into
harmony with creation we are led into harmony with its source.
Everything combined, all the wealth of color, warmth of sunlight, song
of birds, hum of insects and breath of growing things, conspire to the
unfoldment of the being on all the planes of life’s expression, for,
the first and controlling impulse is toward expression; expression on
the physical, mental and emotional planes—in fulfillment of the law of
growth, for expression is a necessity to growth.
_Expression._ Geography has been said to be an analytical study of the
earth’s surface, or the study of the separate landscape elements, such as
form, color and organic structure.
Geography is emphatically a study of form, the forms of the earth’s
surface features, each to be studied in relation to other and contrasting
forms, as well as in relation to their environment.
Upon the pupils’ return from the field, the forms and areas observed
may be modeled in sand, sketched on paper, or chalk modeled on the
blackboard. Maps may be drawn of the areas studied and sketches may be
made in color of stretches of different soils and verdure, together with
the atmospheric effects observed. Tints of sea, sky and cloud, color and
shades of rock and foliage are all speaking in tones which the child may
interpret and render intelligible to others, through the medium of brush
and paints.
It is of great importance to his future growth that the student acquire
the habit of freely expressing himself through the art modes of modeling,
painting and drawing, since much of his mental power depends upon such
expression; for by holding in mind, while in the act of expression, the
images acquired through observation, more of the details of the object or
scene as well as the generalities are recalled.
[Illustration: RIVER BASIN.]
Expression thus reacts upon self, causing the mental picture to be
intensified and expression to become more definite and complete. No
other means are so adequate to this end: _i.e._, the forming of distinct
images in the mind, unless it may be the giving of oral and written
descriptions. These, of course, should be demanded of the pupil as well.
By this demand the pupil sees the necessity of closer observation and
investigation that he may give a fuller and more truthful expression,
and with careful leading he becomes a critic of his own thought and
skill, which is a step pre-eminently educative.
_Aim of Field Lesson._ A direct purpose or aim of the field lesson in
teaching geography should be to form a clear idea or mental picture of a
river basin as a basis for imaging other river basins, and as a unit for
the study of the continent, or of all land surface: and to know the river
basin is to know its history; that is, the history of the river itself,
its valley, and the story of its building and shaping.
It may not be possible for all students to make a study of the whole of
a river or brook basin, yet it may be done by sections—getting a general
idea of the slope of the river bed, water-parting, slope and valley.
The action of the forces of nature may also be seen in the changes now
going on in the different sections—the cutting back of the stream at
its source, its eroding power, its carrying power, and its building or
leveling power.
If it is not possible to take the children to the field for nature study,
they may find fruitful sources of study without.
_City Schools._ Nearly every school-house has some surroundings that may
be studied to advantage, except those in closely built city streets; but
even in such cases there is always the work of rain, heat, frost, and
wind to study, as well as insect life. The drifting of sand and snow, the
frost on the window-panes, the forming of ice around doors and windows
and the effect of heat in its melting, rain-drops, clouds, puddles of
water in the slight depressions of sills and walks, with tiny streams
flowing therefrom, are all to be observed.
Where did the dirt on the windows and sills come from, especially after
some snow-storm? Tiny seeds in the corners where the winds have left
them; insects in the spring;—where did they come from? Where were they
all winter? These and many other hints might be given for such study.
[Illustration: THE CUTTING BACK OF A STREAM AT ITS SOURCE.]
_The country_ furnishes a rich field for investigation. Around every
building and in many localities that can be easily reached, most of the
types of the earth’s surface forms may be found. Care must be taken that
they are considered as _types_, or the pupil might answer the question,
“How high are mountains?” as the child did who said in reply, “Two inches
high.”
In the lower grades of school, much of the geography work should be the
direct lesson in the field followed by lessons in school. The higher
grades, also, should continue the frequent field excursions which are
begun in the lower.
[Illustration: SOURCE OF BROOK IN NEARLY LEVEL COUNTRY.]
Visits may be made to the hills, groves, lakes and ponds of the vicinity,
and upon returning to the school-room, these and surrounding areas may
be modeled in sand or clay, painted in water-color or drawn on the
blackboard.
[Illustration: FARM IN CENTRAL NEW YORK.]
Brook basins may be studied as presenting many if not all of the features
of the river basins. Maps may also be made of these areas, as well as
detailed drawings of special features.
As has been said, the pupil should model and draw continually, in
connection with or after every lesson in the field. It is the very best
method by which to attain mental growth, and should of course, be the
genuine expression of his own mental images gained through observation.
He should model and draw all surface features or areas seen in his
excursions. He may model, in sand, putty or clay, maps of the areas of
the school-yard, farms or parks in the vicinity; or chalk model them,
then indicate upon them the boundaries of any sub-divisions they may
have, such as fields, clumps of trees, houses or other buildings.
[Illustration: MAP SHOWING ITS RELATION TO THE BROOK AND RIVER.]
_Imaginary Areas._ Let the pupil also sketch on the blackboard, imaginary
scenes and typical features of other areas and countries under the same
or contrasting climatic and other conditions; always questioning, as he
draws his mental picture—if of a river, for instance—what is the cause
of its rapidity, what its probable depth and effect on the soil, why it
cuts here or builds there, and why the slopes back of it are terraced as
they are.
If he represents islands, he should ask himself the question why they are
rocky or alluvial; _i.e._, what their origin; and never represent in any
expression that which is contradictory and so untrue to nature.
Landscapes typical of the different zones of temperature, showing
characteristic structure, vegetation, homes, habits and occupations of
inhabitants may be drawn.
Maps, also, of these areas and those adjoining, may be chalk modeled.
As the mind becomes stored with separate images acquired through actual
observation of areas of the earth’s surface, gradually, by the combining
and blending of these, a new mental image, a comprehensive picture is
formed, corresponding in the main to the general features of the whole
earth, with its uplifted masses and lower plains, its natural divisions
of continents, seas and oceans, its atmospheric and climatic conditions.
If the habit has been formed of chalk modeling imaginary areas, as well
as those within the sense grasp, it will be a comparatively easy matter
to chalk model a map of the whole continent. On this the student may mark
the boundaries of all political divisions as he studies them, and locate
the important cities and places of interest.
_Practical Suggestions._ Before we leave the subject of field lessons,
some practical suggestions in regard to them are here offered.
Actual observations may be made on the action and effects of rivers,
underground water, rain, wind, heat and frost.
The effects of glacial action, and the eruptive forces of nature may also
be seen in places.
To study river action it is not necessary to visit a river (if there
be none near); any small stream of water, any tiny rivulet beside the
roadway, tells its story of wearing and building, its vertical cutting
and its swinging from side to side. It has its miniature valley, its
basin and water-parting and possibly a delta at its mouth. It may also
have its cascade or waterfall.
[Illustration: RIVULET SHOWING FALL OF WATER AND DELTA.]
The wearing of rock, through the influence of rain, frost and heat, may
be seen in any stone building, fence or pavement.
Effects of heat and moisture on vegetation, as influencing the growth
of plants and trees, should be noticed. The growth of shrubs and trees
during a dry season can be measured and compared with that of wet seasons.
The observer should mark the effect of vegetation in the action of rain
on a grassy slope—how the grass protects the soil, preventing it from
being washed away, and how, by holding back the water so that it flows
more slowly, it is less destructive in its action.
To add to the interest, the pupil may be led to imagine the effects upon
climate and streams, of the denuding of large areas of their forests;
also how rock sculpturing, in the forming of gorges, cañons, etc., would
be modified by the volume and force of streams.
Observation should also be made on the making of soils, their
constituents and relative proportions of loam, sand, gravel and clay, and
the relation of these to plant and animal life.
The part that the common earth-worm bears in constantly uniting,
enriching and otherwise preparing the soils for the support of vegetable
life, may be seen in many areas. (It has been computed that in one year
several tons of soil are brought up and distributed by them, within an
area of an acre of land.)
A study made of the action of underground water, as shown in common and
intermittent springs, would be full of interesting suggestions.
The effect of glaciers may be seen in part and their tremendous influence
imagined, by the presence of the countless numbers of striated boulders,
pieces of rock and pebbles, which are strewn all over our prairies
hundreds of miles from any mountains which could have been their home.
It is not necessary to witness the devastation of a cyclone in order to
study the effects of wind action. The piling of sand on the sea-shore,
the drifting of snow or the whirling of dust in the street illustrate
this. The observer may notice where the dust blown from the street has
choked and buried the grasses and weeds beside it, and imagine what might
be the fate of forests in the path of encroaching sand-dunes.
[Illustration: SAND-DUNE ON THE SHORE OF LAKE MICHIGAN.]
Pupils may be told of the dunes which travel great distances: that one
way by which this is known is by noting trees and houses that were once
back of the traveling sand-hills and are now in front of them; also tell
of the sites of ancient cities long buried and now being excavated and
brought to light again.
IMPORTANCE OF LEARNING TO INTERPRET PICTURES AS AN AID TO IMAGING THE
CONTINENT.
The ability to image the continent or any part of it, from the reading
of pictures, is of great importance. It is an inexpressible aid to the
imagination in the study of areas that lie outside of the sense grasp.
Good pictures should be chosen: pictures showing several different
views of the same section of a country; pictures that are a truthful
representation of both detail and generalities. (Many wood cuts are as
good as photographs for this purpose. Great care, however, should be
taken that they are faithful transcripts.)
After a close study of them, questions may be asked the pupil as to
climate, structure, nature of rock and soil; whether it may be supposed
to be an arid or fertile region; whether the river basins are young or
old; what agents were most active in shaping its features, and what its
probable destiny: or the pupil may be led to give his own inferences as
to conditions, without direct questioning.
In this way contrasting sections of country may be studied and compared,
thus making the mental picture more vivid and complete.
[Illustration: MAP OF ABYSSINIAN HIGHLAND.
(Drawn from information gained through interpretation of pictures and
written description.)]
It is understood that these mental images gained from such study of
pictures, have as a basis, images acquired from actual observation of the
earth’s surface. From this mental picture, supplemented by images gained
by oral and written descriptions, maps may be chalk modeled which will
contain all the essential features of structure.
[Illustration: YOUNG RIVER BASIN.]
Valuable information for the making of maps has been gained in this way;
indeed, adequate maps cannot be made without this means of acquiring
the necessary knowledge, which the delineator has not been able to gain
through travel and personal investigation.
Through this study or reading of pictures a natural interest is aroused
in the mind of the pupil to see located on the map (that is, to see in
relation to the whole) countries and places of special interest; such as
natural wonders of structure, and remarkable instances of man’s skill
and power in overcoming obstacles and improving his environment.
Especially will this be the case if the teacher accompanies the
descriptions with rapid illustrations on the blackboard.
[Illustration: TEPEE OR WIGWAM OF THE SIOUX INDIANS.]
Necessity for skill in drawing on the part of the teacher, becomes very
evident as the desirability of frequent illustrations is felt, and the
fact is also realized that by it untold influence for good is exerted
over the mind of the pupil. It is an aid to correct mental picturing,
which the teacher cannot afford to omit.
[Illustration: COAST OF ALASKA.
(Showing its drowned valleys caused by the gradual sinking of the land,
also glaciers, Alaskan hut and totem pole.)]
Special features are more readily understood when drawn in detail: as
mountain peaks, stern or forbidding in outline, or lofty and grand
in their mantles of snow and rivers of ice (Mt. Blanc); valleys
with wooded slopes and streams of water; lakes, waterfalls (Niagara
Falls); glaciers and icebergs, with typical scenes of Arctic regions,
including inhabitants with their homes (Muir Glaciers), (Alaskan huts
and totem-poles); deserts and oases, with typical trees and surrounding
objects (palm trees, pyramids, camels); Indian homes and environment;
dykes of Holland, Suez Canal, St. Gothard Tunnel, Great Wall of China,
etc.
[Illustration: THE CHALK MODELED MAP.]
MAPS OF THE PAST AND PRESENT.
As it is impossible to adequately teach the surface features of a country
with only a vague idea of its structure, and with no aids in the form of
pictures, drawing or modelings by which these surface features may be
illustrated, there arises the necessity for maps.
These, to be of any real service, must be a representation of the form
and character of the area which is the subject of study, and must
indicate the relation of part to part, parts to the whole, and the whole
to parts.
As symbols and more than symbols, they must bring to the mind vivid
pictures of the real country or continent, not as too commonly taught;
“A mental picture of the map, so clear and consistent ... that he (the
pupil) can read the answers to all questions concerning it, from his
mental map, as easily as he could from the printed one, if it were before
him.”
This is to limit and cramp the mind’s action, as the pupil sees only
the map and its corresponding concept of map, its size, boundaries and
patches of colored paper. It gives no idea of relation or correspondence
between the map and the actual world of life, form and color.
_Aim of Teacher._ In using maps it should be the aim of teachers
to create in the mind a complete, harmonious picture; the blending
together of the several concepts of structure, climate, drainage, soil,
vegetation, animal life, races of men, etc., corresponding to reality,
or real life in the real world.
_The flat political maps_ of the past made no attempt to show any
structural features except those of horizontal or level plains, markings
which show the locations of mountain ranges and volcanoes, and lines
indicating rivers and outlines of continents or coasts.
These maps have had comparatively little meaning to the young pupil.
There was in them no suggestion of solidity or mass; the contents to him
seemed flat and thin, and confined between coasts which were sharply
defined. Tent-like mountains crossed ghost-like surfaces, and thread-like
rivers were made to zigzag along in an erratic and irresponsible way,
showing to him no reason whatever for their being.
Many teachers or pupils have not known how to interpret maps. They have
not realized that, where rivers rise in certain localities (especially
if more than one rises in the same place), there is a reason for their
rising just there and for their flowing in different directions; that
their source is probably at an elevation or rise of land (called a divide
or water-parting), that there is likely to be more rainfall on the side
of the mountain range that has the more rivers, and that this has a close
relation to the direction of the prevailing winds.
_Natural Boundaries._ In the past study of these maps, outlines of
political divisions have been memorized. It was not realized that many
of the boundaries of those areas were fixed in the beginning by the very
nature of the surface structure, and that they are where they are, simply
because they could not well be anywhere else. (See Mexico, India, Italy.)
[Illustration: MAP OF THE CHICAGO DRAINAGE CANAL.
(With larger map showing its relation to Lake Michigan and the
Mississippi River, also sections in detail.)]
_History._ We have seen that the study of history cannot be successfully
taught without a knowledge of structural geography on the part of
teacher and pupil; so we may say the same of maps, that their use is
of fundamental importance in that study, and the ability to read them
understandingly is as indispensable as it is in the study of geography.
To try to teach history otherwise would be a waste of time and effort.
The habit of locating the events recorded, of tracing upon the map
the route of an army, or the line of an important road or canal, and
observing the impediments or natural obstructions to be overcome, with
the great advantages to be derived therefrom, together with inferences
as to the time and labor required, has the effect of making the study of
history of living interest, especially if the map used indicates such
surface structure.
In the structural map the student readily sees the meaning to commerce of
the cutting of a canal which would unite two large bodies of water, or
the effect the building of roads and bridges across hitherto impassable
regions would have upon the life and growth of a people in the opening
up of new and extensive areas to civilization, and consequently the
development of their own internal resources.
The importance of this habit of usage, or constant reference to the
map, is also recognized when one realizes how it fixes in the memory
not only the location of cities and boundaries of ancient empires, but
the geographical structure and environment associated with their growth
and with important historic events; making plain the reasons for, or
causes why, certain events occurred at certain places, as the inevitable
consequence of their environment.
Light dawns upon the pupil as he studies. He sees that environment has
been an important factor in the development of the human race. He traces
step by step in imagination the growth of civilization, from the time
that man in his nomad stage first drove his herds into the valley in
search of food and water. There, finding the soil productive, water
unfailing in supply, and the valley protected from marauders by natural
barriers, as desert or mountain walls, he fixes his home; in the course
of time comfortable dwellings are constructed, land is cultivated and the
place becomes a center of civilization.
In connection with this train of thought, the student by contrast notes
the far different effects of environment as shown by life in the Arctic
or other regions, and he turns to his map with renewed interest and eager
inquiry.
_Literature._ The habit also of locating on the map every place, natural
feature or country read about, should be cultivated, as it is of
importance in obtaining a correct understanding of an author’s meaning.
If we did not have the knowledge of physical structure in mind as a stage
on which the actors move, much of our literature would lose its value,
becoming flat and uninteresting.
To know the great lake region adds to one’s interest in Longfellow’s
“Hiawatha,” and the tales of the early explorers; and a knowledge of the
Catskills and the geography of the Hudson River valley gives greater zest
to the enjoyment of Irving’s “Rip Van Winkle” and “Sleepy Hollow.”
It is also necessary to the understanding of the stories of Holland
(“Hans Brinker”) that we know the habits of the Hollanders arising from
the physical characteristics of their environment.
To read intelligently Scott, Dickens, George Elliot and others is to
understand the peculiarities of climate and structure of the British
Isles. The old Greek stories and the German Folk Lore as well, demand
for their understanding and interpretation, that we place them not only
in relation to the habits and thoughts of the people, but also to the
physical foundation of the country itself.
_Relief Map._ The nearer a map corresponds in its inherent form and
material, to the surface features of the earth which it is designed to
represent, the more of reality does it recall to the mind. The most
effective map of this kind and the one which corresponds most closely to
the reality is the modeled map of putty or plaster, showing structure in
relief.
These maps have been in use for years, and have been of incalculable
interest and benefit to those whose stock of knowledge concerning
geographical structure had been mainly gathered from the flat political
map and old modes of teaching.
On seeing a relief map of one of the continents for the first time, there
arises a sense of wonder and surprise, and as the realization dawns upon
one of the continuity of the great mass of land represented, with its
altitudes and depressions, and that it is one stupendous aggregation of
soil, rock and vegetation, surrounded by a great expanse of water, a
feeling of awe and astonishment is awakened.
As this new light comes to the student, he looks with interest and
eagerness to see the plan of it all. We do not mean to say that he
sees in the map before him an actual correspondence to the earth’s
surface structure, that is, forms that are reproductions in miniature
of mountain range and valley, but he sees a representation of them
calculated to arouse his imagination to a lively degree. He is enabled
to picture to himself great slopes crowned by lofty mountain peaks,
and the meeting of their lower edges where mighty rivers flow. He sees
in imagination how these waters have cut deep channels into the great
uplifted masses, how they have torn jagged gashes into their rugged sides
as they leaped and tumbled through dark cañons, grinding off rocks that
form sediment constantly to be deposited later on upon the plain below.
He easily understands that they must act as a source of drainage for wet
lands and as channels for the irrigation of dry areas.
In looking upon the great bodies of water, oceans, seas, lakes and gulfs,
as represented on the maps, he questions the relation of these waters
to the land, their depth and what place they fill in the economy of
nature. Indeed, the relief map has an awakening effect, quickening the
imagination and stimulating to mental effort—earnest thought.
They are invaluable in their place and have come to stay; yet on account
of their weight and general unwieldiness they are not practically as
useful as maps which are lighter and more easily handled.
_The papier mache_ maps in relief, although much lighter in weight, are
still very bulky if made large enough to be of much practical use as
wall maps, since they cannot be folded or reduced in size to facilitate
transportation, or removal from room to room.
The best of these, also, are modeled in such low relief that they are
better adapted to the use of pupils in the higher than in the lower
grades. Other maps of rather recent date are the _typographical_ map and
the _contoured_ map. The former shows general altitudes by the use of
shades of color, and is of great value to one who can interpret it, but
only a confused mass of signs and symbols to the young student, and thus
not much more helpful to him than was the old reference map.
In the contoured map, the altitudes are scientifically represented
by lines drawn to an exact scale, and such maps are most valuable to
students of the higher grades.
A structural map suitable to all grades of pupils, the lower as well as
the higher grades, seems highly essential; especially should it be one
that is adapted to the teacher’s use while before the class—one to teach
from. This should be entirely different from a reference map. It should
plainly show the great facts of physical geography or surface structure,
as well as some detail, and this in a simple form. For the lower grades
there should be no lines to mark the political divisions, neither
should there be any names of countries, states, or cities to designate
localities.
Everything should be omitted that would have a tendency to divert the
attention from the chief function of the map which is, to aid in the
formation of a mental picture or image, corresponding to the structural
features of the real country or continent.
_The Chalk Modeled Map._ These maps, following the use of the putty or
plaster relief maps, should be the only ones placed before the pupils
of the third and fourth grades, or even higher grades, until they have
gained mental power to read and understand the signs and symbols of the
map, and realize clearly the chief structural features of the whole globe.
The student should be enabled by the use of maps to picture in his mind
the configuration of the whole earth; the distribution and shape of land
and water surfaces, the great structural division of continents, the
slopes and counter-slopes with their crowned heights and level plains,
the great land masses and river basins, peninsulas, gulfs and bays,
islands and their relation to the mainland.
In fine, the whole world surface should become a reality to him if the
map is rightly taught. This will be an easy matter for a teacher who
is alive to the beauty of the world around us and who has a personal
knowledge or clearly pictured concepts of the real country. Such an one
will readily see the value of the maps as an aid to the pupil in gaining
a comprehensive mental picture of the earth’s surface.
She will remember that the mere placing of the maps before the pupil is
not enough, that they will be as unmeaning to him as the flat political
map, unless he has already in mind the primary concepts acquired through
observation of surface forms, and has made his inference as to cause from
the effects seen.
Of what value will it be to him to know that certain lines indicate a
mountain range or river, unless he has an approximate idea of what a
mountain range or river is?
For the use of the more advanced pupils of the higher grades, who see
the relation of structural environment to man in his development as
a nation, the relation of natural structural divisions to political
divisions, these maps should have lines drawn upon them to indicate the
boundaries of such divisions. Names, also, of countries, mountain and
river systems should be marked, and the large bodies of water of the
interior. Later on, the smaller divisions of states and provinces, gulfs
and bays, lakes and rivers, with their tributaries, should be shown, and
important cities may also be located; in the end, all the data needed as
a reference map.
The map devised to fulfil these conditions, and now in considerable
use in this country, is called the “Chalk Modeled Map.” It is drawn to
represent surface structure in relief, giving much of the effect of an
engraving or photograph of a relief map, yet intrinsically more truthful
and artistic than any such representation could be.
There is an immense difference between this and a drawing from a relief
map, or from a photograph of one. In this map the delineator expresses at
first hand his own concept of the continental structure, as the artist or
poet expresses in his work his own original ideas. We feel his thought in
the very quality of line used. We read how the truths have appealed to
his own consciousness. It stands where the relief map itself stands, as
representing the delineator’s own mental image of such structure.
There are no lines drawn in this map that contradict or confuse the
meaning; all is direct, truthful and clear in statement of fact. Each
line has its own particular meaning. If represents direction. Applied to
land surface, a vertical line means a perpendicular mountain or side wall
of plateau, horizontal lines indicate level areas, and oblique lines a
sloping surface.
Until recently, this map has not been available for general use, except
as each teacher made his or her own. The latter, however, is the ideal
way of teaching. To draw a map of a continent or section of it, as is
required, in order to illustrate or emphasize any particular point before
the class, adds intensely to the interest of the lesson and to the
adequacy of concept gained by the pupil.
Too often, however, the opposite course is pursued. The teacher’s
conceptions of earth structure are perhaps vague, or, teachers may not
have been in the habit of representing by drawings that which they may be
able to picture quite clearly in their own minds, even the desirability
of so doing may not have been entertained by them.
In fact, there are comparatively few who have been persistent enough to
make maps, for though there may be a good knowledge of geography, clear
mental pictures of structure and the ability, also, to draw them, yet
lack of time necessary for their proper delineation has doubtless often
compelled the busy teacher to forego their execution.
_Printed Wall Map._ The Chalk Modeled map has recently been presented to
us in a more durable and serviceable form for general use; a printed wall
map, which combines the latest geographical knowledge together with the
best available skill in delineation.
It does not embody all the desirable points of the original, yet it has
an added one, that of durability.
The introduction of “Nature Study” into the public schools has
contributed largely to the demand for such a map. Pupils brought into
close relations with nature, naturally seek to relate the knowledge
gained in this basic study of geography, to the map; as in connection
with the field lessons, after actual observation of surface areas, the
student is led to model or draw what he has seen. This he represents in
pictorial form, as it appears to him, or he charts or maps it from actual
measurements.
Sometimes he tries to combine these methods so as to show elevations as
altitudes on his map or chart, but the results are often very crude; a
mere representation of hills and mountains piled up on level ground.
He realizes that this is not a proper representation and is often
discouraged. He knows that peaks are related to level ground by
continuity of mass: that they are the corrugated tops of great uplifted
masses or swells of land, and his failure to find this illustrated in the
old maps has led him to lose much of his interest in them, and to greet
the new one with ardor.
It appeals to his reason as a symbol more nearly corresponding to the
features of the country represented. It is indeed the link needed to
connect the political map with the putty relief map.
_Mass Without Outline._ Not only can we say that the Chalk Modeled map
has been a great factor in the better understanding of the surface
contour and conditions of the continental mass, thus advancing the
true study of geography, but that it has also awakened some of the
teachers of the public schools of the country, to the lack of interest
and lifelessness in the teaching of drawing as it has prevailed in the
schools in the past. It has been the means of revealing to them the
beauty and desirability of delineating mass without a continuous hard
outline. The artist when inspired with his subject masses his material in
boldly and each stroke counts for the thing he wants to say—it tells of
the direction of surface, or edge of mass, or detail.
In the new map, the representation of solidity and land continuity as
mass, with no hard and fast limitations of land and water, such as the
outlines so prominent in the old reference maps, is a noticeable feature.
It is a well-known fact that a general or approximate shape of the coasts
of continents is all that can be known from the most careful surveys;
for in reality with every season there is more or less change in coast
line, caused by wearing and building of ocean and river, as well as by
the occasional rising or sinking of stretches of land along the coast. In
course of time these changes become very apparent.
The omitting of outlines of continents, then, in the drawing of maps
has been for a purpose. They have not been necessary to the showing
of limitation of continental mass or the meeting of the surface plane
of water with land surface; and as the direction of all lines used in
delineating have their meaning, there can be truthfully none used to
represent something lying between land and sea, as there is nothing
there. Continental coast contours may be as accurately shown as the
occasion demands without the use of any outline to confuse the eye or to
contradict the direction of line used to delineate the structure of the
land surface at the water’s edge. (See map illustrations in Part IV.)
The most prominent feature of the new map is the representation of the
relief of the earth’s surface; showing, as it does at a glance, the
great back bone of the continent, with its ragged broken line of peaks
dividing the waters of the two slopes; its great land masses, primary and
secondary; and its area or line of greatest depressions. Its river basins
also are plainly seen, and we infer the reason for the general course of
the rivers and read their history from the sculpturing they have done.
We may note also the character of the mountain ranges; whether they are
young or old; where new land is being made, and where areas are sinking.
One can often determine what the prevailing wind of a section may be
and the regions of greatest rainfall, and can judge of the climate and
vegetation; in short, very rational conclusions concerning the life and
habits of a people may be formed from a study of the map alone, and the
student can picture, in imagination, the growth or advancement of nations
under the given conditions.
He will be enabled to see, as has been remarked in substance before, that
the mighty influences bearing upon civilization have always been largely
dependent upon the geographical structure of a country; the relation of
natural divisions to existing political divisions will be noted, and the
reasons for the locations of great centers of commerce, important cities,
and military fortifications, will be understood.
_Altitudes._ In common with all relief maps, altitudes are shown in
these, greatly exaggerated in comparison with the horizontal distances,
but this is essential in order that the pupil may be able to grasp the
_general truths_ of the organization of the continent.
Relief maps in relatively exact proportions will not help to this, as the
highest elevation would appear nearly on a plane with the ocean level,
and would be of no better service for school use than the flat maps,
from which no idea of the general organism can be acquired by the young
student, if indeed it can be by one of riper years.
Also in all topographical surveys, and in the profile of vertical
sections of country found in many geographies, we find the same
exaggeration of height in relation to horizontal distances, used to
illustrate elevations and slopes.
These, with photographs or pictures of relief maps are extensively used,
as well as birds’-eye views, showing on the part of the map-makers, a
recognition of the importance of the pupil’s gaining mental concepts of
altitudes. The latter, of course, must exercise his judgment in relating
the heights, to the horizontal distances given, as he so continually does
in every-day life in regard to other matters.
The horizontal map distances should be related to the other horizontal
distances of the map, and the altitudes to other altitudes, and these
with reference, also, to the tabulated lists found in every geography, of
the heights of mountain peaks and lengths of rivers.
“All knowledge of external things comes through observation, comparison,
and judgment.” To judge of great altitudes, one must have a knowledge of
the heights within experience. To be able to gain a proper conception of
immense distances, as the distance across a continent, comparison must be
made with the distances one has already measured or traveled.
In the measurements of areas, size of fields and gardens, width of ponds,
or heights of trees and hills, the pupil has numerical facts from which
he judges of other forms and areas; as forests, marshes, plains, the
width of rivers and lakes, the heights of mountains and cliffs, or length
of rivers and mountain ranges.
Also in the measuring of the deposition of silt in small streams, he may
judge of the quantity that large rivers like the Mississippi or Nile
must carry; and from measuring the yearly growth of vegetation in his
own climate, he judges what might be the growth in other climates. Thus
through observations, inferences, and comparisons, he is enabled to read
his map with some degree of power to judge its distances and altitudes.
The aim in the preceding pages has been to show the vital importance to
the would-be delineator of Chalk Modeled maps, of the thorough study
of geography, in its truest sense, and that the foundation of such
study lies in the field lesson, with its accompanying expression of the
knowledge gained there, of surface forms, areas and structures.
The habit, also, of modeling and drawing in connection with the study
of geography, is conducive to the wished-for end; _i.e._, an adequate
knowledge and expression, of the surface contour of the continent.
The chalk modeling of maps is in itself the simplest of all modes of
drawing. It may have been inferred from what has been said on the subject
of maps, that drawing them consists merely in showing simple indications
of slopes; short or long, abrupt or gentle, and summits; broken or
rounded, river basins, character of water-partings, valleys, lakes,
rivers and coasts either bold and rocky, or low and alluvial.
It would be as unnecessary for the purposes of geographical instruction,
as it would be impossible, to draw absolutely correct maps of the earth’s
surface.
Each mountain peak cannot be shown, nor every indentation of coast-line,
but the general trend or direction of mountain ranges and rivers, and
more or less of geological structure can be portrayed in a conventional
manner.
It is not difficult to chalk model with reasonable accuracy. The ability
to do this, however, with any degree of rapidity as well as accuracy,
implies, as has just been said, an adequate knowledge of the subject
to be represented. No mere imitation, or acquisition of technique, or
copying of maps, is educational, nor has it any vital relation to the
true study of geography. Like all dead copies, it betrays in itself its
lack of life, or of real knowledge on the part of the delineator.
An instructor whose eyes are open to truth, can generally tell from a
pupil’s representation whether it is the result of his own individual
thought, the expression of his own knowledge of the subject, or the
reflex of another’s thought.
If it is an expression of his own, there will be much revealed in the
touch and in the quality of line itself, that could not be depicted in
form or put into words. The representation, also, will indicate to what
degree the subject has interested and inspired the individual, and how,
with a clear mental image, he has instinctively expressed himself in the
simplest and most direct manner possible with the medium at hand.
In the following pages will be found suggestions as to the method of
chalk modeling, given in the form of a series of lessons; the underlying
principles in the lessons being those on which is based all expression of
thought in every field of study and among all peoples.
The illustrations are not intended to be models for the teacher or pupils
to copy, but are meant to be helps or encouragement to those who desire
and have courage to attempt to express their own mental images.
Busy teachers need only to realize that comparatively little effort is
necessary in order to acquire a certain amount of success, if they have
their subject in hand, that is, if they have an adequate mental image of
the object to be sketched.
It is hoped that such success will prove a strong inducement to a
deep study of the subject of art, and especially to the psychology of
expression.
PART II.
LESSONS.
REMARKS.
Chalk Modeling of surface forms is the easiest and simplest method of
geographical drawing, and one of the best ways of beginning art work in
the school-room, for absolute definiteness of form and detail is not
required, and we know that generalities are represented much more easily
than details—large masses more easily than small objects.
No one need hesitate to try to draw who can write or gesture: this last
we are all doing continually, either consciously or unconsciously.
Watch the friend while telling some interesting story, or while giving a
description of some object or landscape. Note the gestures unconsciously
employed and how truthful to the subject they are. Also notice that the
more intense the desire to make you understand, the more adequate is the
gesture.
No conscious thought is required as to what motion to make, for the very
desire to express brings with it both the required word and action.
This is spontaneity, and if a pencil or crayon were in the hand of the
narrator, with paper or a blackboard near, a sketch might be the result,
and one quite adequate to its purpose.
If you are in earnest and truly desire to express your thought by drawing
or chalk modeling, you will forget yourself in your effort to be
understood. You will find a way to accomplish your object, choosing and
using the right direction of line and giving the right accentuation or
emphasis without any special attention as to the method of working.
Drawings may be made on the blackboard with common blackboard crayon of
medium softness, or with charcoal or crayon upon paper. The blackboard is
much the more serviceable, as upon that you can draw with great freedom,
without fear of wasting paper or of spoiling your work. Swing the arm out
freely from the shoulder as you work, give out that which you have to
give, without fear, generously. If it is but a line to indicate the edge
of a table, draw that line as though you were _glad_ to draw it. Express
your thought boldly regarding the fact or object you wish to make your
statement about—fear not.
REPRESENTATION OF SURFACES WITH HINTS ON THE DELINEATION OF DISTANCES.
LAND SLOPING _FROM_ THE OBSERVER. LIGHT AND SHADE.
The most convenient length of crayon to use, is a piece about an inch and
a half or two inches long, yet we may often profitably use the whole side
or length of the crayon. If we wish to represent broad surfaces, we will
naturally use the side of the crayon, as a child does. To show narrower
widths of surface press more upon the end of the crayon, also use a long
_edge_ to represent the edges or the meeting of surface planes. This
manner of using the crayon seems the most natural for the purpose, and it
certainly economizes time.
Line represents direction. When applied to surface we understand it to
indicate horizontal, vertical, oblique, and curved surface directions.
Try it and see if it is not true that lines in one direction never
indicate any other direction; the vertical can never be mistaken for the
horizontal, or the reverse. For the representation of a level plain,
make simple strokes in the horizontal direction with the side of the
crayon, and to represent a vertical surface as a cliff, make a stroke in
the vertical direction with the same broad side of the crayon. Oblique
surfaces, as slopes, are to be drawn with oblique strokes, and curved
surfaces like rounded hills, represented by continuous upward and
downward strokes. (See Fig. 1.) In the delineation of mountain masses,
that are high with abrupt declivities as well as gradual slopes, we use
the side of the crayon with an oblique stroke as in Fig. 2. We see then
that right direction of lines of themselves illustrate surface planes,
elevations or depressions.
[Illustration: 1 2 3 4 5]
Detail of structure, however, cannot be well brought out except by
effects of light and shade. Choose from which direction your map or
sketch is to be lighted, and keep it always in mind while drawing. Study
the effects of light and shade everywhere. Note the length of shadows at
different times of the day, and their relation to the position of the sun.
To represent an unbroken sweep of land or water, as of a plain or lake,
draw a broad unbroken line for the distance, as all detail of surface
forms seems to merge into one horizontal mass; nearer to us, we perceive
more detail of landscape or broken land surface, which we may represent
with broken lines. This is the most simple representation of level
distance. (Note Fig. 3.)
In Fig. 4, or the representation of a plateau (upraised mass of land),
there are horizontal, vertical, and oblique surfaces combined. The detail
of structure in the foreground is represented with some definiteness
of line, while the mountain slopes are quite indefinite. Notice that
the oblique and vertical lines are shorter in the distance than in the
foreground, and that the land seems to rise as it recedes from us. Look
out of doors and see if it is not so. Notice rows of trees, houses, or
telegraph poles, in their relative height, also in their relation to the
ground on which they stand.
In the delineation of a valley between parallel mountain ranges, keep
in mind the proportionate height of mountains to width of valley; for
example, think of the apparent width of street or railroad track at the
farther end, in comparison with the width of the same close by you, and
also notice that it decreases in definiteness as it recedes into the
distance. Note the width of the valley in Fig. 4.
Fig. 5 represents land sloping from us as it recedes. Note the more
definite lines in the foreground, indicating some detail of structure,
and the indefiniteness, or less distinct lines that indicate the distant
hills, these lines becoming more and more indistinct as the hills recede.
[Illustration: 6 7 9]
LAND SLOPING TOWARDS THE OBSERVER. QUALITY OF LINE. RELATIONS.
Each line drawn has its own characteristic meaning—its own individuality,
so to speak. It not only represents direction, but carries with it a
certain quality of effort or mentality, as indecision, fear, courage,
certainty. (See Fig. 6, _a._ _b._ _c._) We also see in it the habitual
mental attitude of the delineator. This is plainly seen in the quality
of line used by the timid, contrasted with that of the fearless—by the
unstable or changeable mind in contrast to one who is clear in his
thought (who “knows his own mind”) and positive in his expression. (_d._
_c._ _e._)
It follows, then, that to draw a firm line with ease and rapidity, one
must have a positive knowledge of what one desires to express, just the
length of the line and its relation to all other lines; that is, one
must see things or objects in their right relations. All things in the
universe are related to each other—nothing stands alone. The mountain is
closely related to the valley, it has given of its substance to build and
enrich the latter, and its streams have carried nourishment to help swell
the river at its base.
In its delineation, therefore, one must keep in mind the relation of its
height to the width of the valley, and to the plateau on which it may
stand; the declivity of its slopes, and their relation to the vertical
direction, which may be seen as an imaginary line drawn from the center
of the base to the zenith.
[Illustration: 8 10]
The trees beside the hill in Fig. 7 show the latter to be very high. In
Fig. 8 the hill becomes low because of the relation of its altitude to
the height of the trees in the foreground.
The delineation of more or less detail also helps to determine altitudes;
as, to draw grasses, boulders or out-cropping rocks on the hill side,
would show that we were near enough to the hill or knoll to see them
in detail. Hills in the far distance would be represented without much
detail, for they are too far away naturally for us to observe it.
To represent land sloping towards us as in Figs. 7, 9, and 10, the
foreground must be broken up, that is, represented in more or less of
structure detail. Fig. 9 shows low hills at the foot of the mountain
range sloping toward the level land in the immediate foreground. Fig. 10
a steep alluvial fan indicating the nature and character of its structure
by the direction and quality of line used. The crumbling sandstone
rock, showing the effects of weathering, is indicated by short nearly
vertical strokes, with the thought of stratification also in mind. The
flowing sand is represented by vertical and oblique lines drawn in the
direction in which sand would naturally flow. We have here three examples
of land sloping towards us. One represented by nearly horizontal lines,
the others by vertical or oblique lines. Grasses grow many blades from
one root. Their tendency may be vertical but many influences combine to
turn them from that direction. Use an edge of the chalk with an upward
or downward motion. Knolls of any contour may be represented by drawing
grasses in the direction of the slopes as in Fig. 8.
[Illustration: 11 12 13 14]
HIGH AND LOW WATER-PARTINGS WITH MAP.
If your subject “possesses” you, there will be no need of giving special
thought to effects or results; these will follow naturally from the state
or quality of feeling engendered in your mind by its contemplation; that
is, if one part of the surface to be represented is hard and rocky, and
another soft and yielding, and you have observed this fact in relation to
the whole, you will naturally show it in the quality of line you use. No
other hints can be given that will help you so readily to the artistic
touch as this, together with the hints given in our last lesson as to
the necessity of an adequate knowledge of form and of relationships or
proportions. Fig. 11. A water-parting high and mountainous. It shows its
rocky structure in the harsh and “liney” quality of the work as well as
in the surface contour. The paper is left white for the streams of water.
On the blackboard, when drawing maps with chalk, use charcoal for the
rivers, as in the rapid delineation of such maps it takes too much time
to save spaces for them; and at the best it is such an exaggeration of
the width of streams, that it misleads the pupil.
Fig. 12 represents a low water-parting. Notice the texture of line, soft
and yielding, produced by thinking, knowing and feeling that the surface
was not rocky, but a somewhat sandy soil, mixed with a little loam.
Perspective is shown by less of detail in the distance than in the
foreground; the trees in the latter being more accurately drawn, as well
as taller. The poplars at the right of the picture also show that the
ground is a little uneven, as the distant ones seem to be partially below
a slight rise in the surface. Fig. 13 is a map or bird’s eye view of a
height of land worn down by streams running in different directions,
leaving the water-parting sharply defined.
A little sketch of the sea shore (Fig. 14) illustrates another quality
of “touch.” In depicting water rolling irresistibly on, a mighty force
dashing against the shore and breaking into showers of spray, you will
naturally use a steady, forceful but light touch in indicating its curves
and masses. “Feeling” and “touch” are something to be experienced and not
taught mechanically.
[Illustration: 15 16 17 18 19]
MEETING OF WATER AND LAND. LAKES, SPRINGS, ISLANDS. HIGH AND LOW TIDE.
The artistic appeals to the higher or finer qualities of our nature, and
to be artistic is to show forth or make visible these qualities. Work
which is truly artistic can only be produced when we are in such harmony
with our subject that these qualities predominate. These truths are so
important that I ask you to experiment and discover them for yourselves.
How will you get the “atmospheric” effect unless you realize that a
certain volume of atmosphere is between you and the distant object?
How will you keep true values unless you see truly (correctly)? In all
drawing of any special subject it should be the aim to keep everything
subordinated to the main point of interest, just as in writing you make
every word or sentence bear upon the main point of your theme or your
argument.
The meeting of land and water can never be represented by a continuous
line; as line indicates direction of surface, and as the surface planes
of both land and water are continually changing, the direction of line is
changing or being broken, even if on the same general plane. Fig. 15 (a
lake among the hills) shows the horizontal plane of water surface meeting
the oblique surface of land. Where the water falls over the rock, the
oblique and curved lines used are broken, to represent the nature of the
rock underneath. Notice that the depth of each little fall corresponds
with the stratification of rock. The water, as it recedes, lies level,
also. You will have no difficulty in drawing ponds and lakes, if you
think of the farther shores as less distinct, and the waves, although
rough and broken in the foreground, as merged and blended together in the
distance.
[Illustration: 20 21 22 23 24]
Figs. 16 and 17 are high and low tide on the Piscataqua River. (The
ocean tides flow in for miles up the river.) These illustrations show
the broken, or short, nearly horizontal lines used to indicate the tops
of the little waves and ripples in the foreground. As the water lowers
a little in the river, the island (Fig. 16) is seen, connected with the
mainland by an isthmus, or narrow neck of land; and in Fig. 17 it is seen
as a part of the mainland. Figs. 18 and 19 are springs flowing out from
hillsides. Notice the relation the grasses and rock bear to the water.
Fig. 20 represents North Cape; Fig. 23, a coral island: both show water
in active motion, compared with that in Fig. 15, and with Fig. 21 (a
rocky island). Fig. 22 shows rapids in a New England stream. Notice the
velocity and volume of water. Fig. 24 is a map of the Mississippi River.
The upper part of the map is drawn without any lines between river and
land. The lower half has a line drawn close to the edge of the water,
to indicate the levees, which are necessary in that region, to prevent
inundation. For a map of continental islands and drowned valleys, see map
of the fiord coast of Alaska, in the Introduction.
SKETCHES ILLUSTRATIVE OF WIND AND WATER EROSION.
All who will may learn to draw. It is that which we most earnestly desire
to do, that is accomplished in every department of effort. All lesser
interests will give place to that which we consider of the greatest
importance. Therefore if we as teachers recognize the value of the habit
of sketching before our classes and greatly desire to be able to draw
with ease and rapidity, we will put ourselves into right relationship to
the work, and will undoubtedly acquire the desired skill.
We have been observing all our lives; we have made careful observations
of many details of form and color, perhaps, and close investigation of
structure, but we have not analyzed them into terms of drawing. We have
not been looking for the planes of surface, or the relative proportions
of parts, or for distance or foreground. Now, however, with the desire
to be able to sketch readily, we will observe the object or landscape
for that special purpose. One sketch will represent only what has been
observed by looking in one direction without turning the head. The most
interesting point of the view will be that at which one looks directly,
and consequently it will be the most important part of the sketch with
every other part subordinated to it.
[Illustration: 25 26 27 28 29]
In out of door sketching it will be necessary to eliminate much that is
seen, only drawing that which is chosen to be the vital or interesting
part of the picture, with that which modifies, or is necessary to show
it in its completeness. Select your point of view, standing at such a
distance that all you care to study may be comprehended in a glance.
[Illustration: 30]
Note the relation of earth to sky, and of trees to hills, streams, or
other objects to be included in the sketch. As a help to find the true
direction compare the surface planes and edges with that which you know
is vertical. Study the light and shade, choose the simple broad tones
which will best express distance, middle ground and near details. Work
simply and easily, not straining after certain preconceived effects. It
is this particular truth or fact which now appeals to you, which you are
to express, and do not hesitate to express it freely and boldly. Sketch
everything, anything, no matter how complicated it may seem to be, and
sketch often. The child does that, and learns to draw by drawing.
[Illustration: 31]
Fig. 25 shows the edge of a desert in Wyoming Territory, where the only
vegetation is sage brush. The rains have worn a little gully in the
general sandy level. Notice the steep slant of the sandy sides. Fig. 26
is a sketch of a hole in the sandy soil of a farm, on the banks of the Au
Sable River, New York. It was first worn by the rains as a little gully
on the upper edge of the bank, and with every rain-storm more sand was
washed out and carried down into the river. A part of this is deposited
lower down the river, below the bank on the right, in the sketch Fig. 30.
[Illustration: 32]
Use horizontal lines for the sandy level, and curved lines to indicate
the slow current in the water. Fig. 27 also shows the result of rain and
wind erosion of the bank behind the stump of the tree. Fig. 28 represents
a section of Yellowstone cañon, and Fig. 29 is a sketch from Monument
Park, Colorado. In both the latter are seen examples of rain and wind
erosion, more particularly in Fig. 29. Notice the hard layers of rock
that cap and protect the softer sandstone beneath, and the hard pinnacles
that jut out from among the sliding sands in Fig. 28.
[Illustration: 33]
The effects of river erosion, together with the weathering of rocks are
seen in Fig. 31, which is a sketch of a section of Wilmington Pass, in
the Adirondacks. The precipitous sides of rock, are shown with evergreens
growing wherever they can find a foothold in the soil made by the
disintegration of the rocks above. Boulders and trees have been brought
down by the loosening of masses of rock, through the action of frost,
heat, and melted snow, causing obstructions in the stream, over and
between which the waters tumble and roll. Fig. 32 is a view taken from
the beach of Arch Rock, at Mackinac Island. It is a mass of calcareous
rock, showing the result of lake erosion and weathering. The rock in Fig.
33 shows signs of disintegration from the action of wind and rain.

SCENES TYPICAL OF THE DIFFERENT ZONES.
Take the children into your confidence: that is, cause them to feel that
you are not sketching for their amusement or for their admiration, but
are trying to help them to a better understanding of the subject. They
will appreciate your motive and be stimulated to increase their own
efforts. With every attempt to sketch on your part, additional skill
will be acquired, for it is only by repeated attempts that progress is
made. By such continued efforts you not only gain the power to express
the knowledge you have, but are led to see wherein you are deficient
and require closer study of your subject. When we try to express our
knowledge of a subject by drawing, we are often greatly surprised to find
how little we know of it. It is the same with writing or speaking. Our
knowledge or ideas of a subject should be arranged in orderly sequence,
so logical and clearly defined, that we shall not be obliged to go back
and modify or correct any part of our expression. Such corrections in
connection with drawing destroy that pleasing quality which marks a
sketch as “artistic.” The teacher who appreciates the importance of
forming correct mental habits, will encourage in his pupils the practice
of accurate and thorough study of a subject, before any attempts at
expression are made.
[Illustration: 35 42 43 44 45 46 47]
In drawing from your imaginary picture, look at it closely and carefully.
Clear it up, classify its component parts into primary and secondary,
that is, decide which is the most important and interesting part of the
whole, and to what degree the other parts are to be subordinated to that,
then analyze it into terms of drawing, _i.e._, vertical, horizontal, etc.
In the scenes given in this lesson as typical of the different zones of
climate, some of the primary features were gained through observation,
some through pictures supplemented by reading. Many of the sketches
illustrating the other lessons, as well as those in the Introduction,
will also give suggestions for this lesson, such as the illustrations on
Alaska, India, and the continents. These need not be duplicated here.
In the scene from Siberia (Fig. 34), and in that of the dunes in
the Sahara desert (Fig. 35), notice the form of both snow and sand
drifts—their sharp edges and short and long slopes. The corn-field in
northern New York (Fig. 36), illustrates the law of receding parallel
lines—that they appear to converge as they recede, and if extended far
enough, would seem to meet at a point on the horizon (the “point of
sight”), a point immediately opposite the eye. A line drawn from the top
and one from the bottom of each stalk in the front row, to the point
of sight, will show this. Notice how the stalks in the foreground are
brought out with more prominence than those farther away and outside of
the direct line of vision.
[Illustration: 41 48 49]
Figs. 37 to 40, inclusive, tell the stories of a lumber camp (Northern
Michigan); logs of cotton-wood floating out into the Au Sable River
(Adirondacks); a scarred and storm-worn pine tree, also one gashed by
the axe of the wood-cutter. In contrast to the pine, notice the graceful
elm of New England, in Fig. 41, and in Fig. 42, the banana tree of hot
climates. Fig. 43 is a scene typical of the hot belt (the Amazon region,
where there is abundant rainfall), and Figs. 44 and 45 show an oasis in
the desert, also cactus, as another typical form of vegetation. Fig. 46
represents a rice-field, and Fig. 47 cotton balls and flowers.
Figs. 48 and 49, showing a factory or “mill” in New England, and the New
York State harvest scene, are typical of the cool belt, or temperate
zone.

RIVER BASINS. COASTS.
Do not copy the sketches given in these lessons. They are but suggestions
to you, who will be able to express your own thoughts and represent your
own mental pictures better than you can another’s. They are given to show
you that simple sketches will help a child to a clearer understanding of
the subject under consideration. As has been said elsewhere, all such
illustrations should be drawn as they are needed to illustrate a given
point in the development of a lesson; for they carry more weight than if
sketched beforehand, that is, outside of the class exercise.
To merely locate in your sketch a house, spring, tree or man, will often
be of great value to the pupil, though you may feel timid about trying to
draw it, or think you have not the time. The experience of many teachers
in this respect may be illustrated by supposing a case.
A sketch is to be drawn, including the figure of a man, animal or any
object which has been considered difficult and therefore somewhat avoided.
The teacher, by one or two rapid strokes in the right direction,
indicates the location and movement of this figure, and proceeds with
the lesson without any hesitation or laborious attempts to really sketch
it. The next time it is necessary to represent it (perhaps in the second
or third lesson), sufficient confidence and skill have been gained to
encourage additional strokes in the development of form, and every
succeeding attempt has resulted in the addition of details of structure,
until almost without knowing it, the necessary skill has been acquired to
make an adequate sketch. How? By _doing_, the teacher has been forced to
form the mental picture, which, once acquired, can be represented, though
it may be more or less crudely at first.
[Illustration: 52 53 54 55 56]
Fig. 50 illustrates the basin of a young river or brook, with its slopes
and system of drainage, just such an one as may be seen near many country
school-houses, and an exaggerated type, only, of what may be found in
the streets and alleys of the city. Its source (_a_) is found in a
slight depression which, in the spring or after heavy rains, becomes
a pond, from which its waters overflow and trickle down through two
channels, which they have worn for themselves. The soil brought down
by these rivulets and others which are tributaries to the main stream,
may be seen deposited at _b_, _c_, _d_, _e_, as flood plains, islands,
and delta. Notice the cañon cut by one of the tributaries through the
left slope of the basin, and the cascade and waterfall where the debris
brought down at high water has formed an obstruction. In Fig. 51 is
given a typical Switzerland river basin. Figs. 52 to 55 inclusive, show
ocean wearing and rock weathering. “Hilt Rock” (Fig. 52) shows alternate
layers of trap rock and sandstone. In Fig. 53 (“Point Portal,” Pictured
Rocks, Lake Superior), is seen the effect of wave and wind wearing in
soft rock, and Fig. 54 (“Land’s End,” Cornwall, England), is an example
of wave wearing in hard rock. Fig. 55 (“Giant’s Cause-way,” Ireland),
shows the weathering and wearing of basaltic rock. Fig. 56 is Eddystone
Light-house, (England).
[Illustration: 57 58 59 60]
In the drawing of maps, the meeting of land and water can be as
accurately drawn by the new method as by the old. The following sketches
illustrate the fact that it is not necessary to use any line running
contrary to the general direction of surface, in order to represent any
contour of coast.
Figs. 57 to 60 are imaginary bird’s-eye views of coasts. Fig. 57 shows
a stretch of level land at the coast, with broken or hilly land between
it and the distant higher hills or mountains: the latter being merely
suggested in the representation. A stream winds its way through the low
land to the ocean, where the silt which it has brought down and the sands
which have been washed up by the sea, form a delta and sand-bars. Fig. 60
shows drowned valleys, fiord coasts, and continental islands.
SUGGESTIONS ON THE USE OF THE CHALK MODELED MAP OF NORTH AMERICA IN
FOURTH AND FIFTH GRADES.
It is hoped that these suggestions will aid many teachers to realize
that the Chalk Modeled maps signify much more than the simple fact of
high and low land, or a representation of structural relief: that from
them, together with suitable pictures showing typical scenes in different
parts of the world, such valuable knowledge of the real surface of the
earth may be gained by the pupil, as will enable him to appreciate the
important relation sustained by man to his environment, and also to his
fellow man.
Previous to the study of the map of North America, the pupil may be
led to imagine the character of the country to the north, south, east
and west of his own locality. He may travel in imagination across the
continent to either ocean, and may study different sections of the
country through pictures and from oral and written descriptions. Such
sections should also be chalk modeled, showing the plateaus, mountain
ranges, plains, valleys, arid and fertile regions.
These drawings should be large, sometimes extending the whole length of
the blackboard from left to right, and drawn in a semi-conventionalized
manner, that is, in a style that combines both landscape, and map
drawing. This is an essential link between the two and should play an
important part in the development of continental picturing: the motive
being (in all this) to have the pupil mentally image the real continent,
before the map or symbol is presented to him. With such preparation, when
the chalk modeled map is placed before him he readily reads its surface
contour.
He notes the great highlands, plateaus, and mountains, the plains,
valleys, slopes, river basins, lakes and rivers.
He is then led to infer the character of soil, climate and
vegetation—everything, indeed, that relates to man’s environment.
He is asked to locate the great forest regions that furnish material
for shelter and articles of household use; to point out the areas best
adapted to the growth of different kinds of food-plants, and also those
that furnish material for clothing; to indicate the grazing lands where
herds of cattle feed; the mining regions, where coal for fuel, iron,
copper, silver, gold, and other valuable metals and minerals are found.
Information necessary to inferences is given at the moment required, such
as altitudes, horizontal distances, latitude, etc. The pupil is also
encouraged to read and acquire knowledge upon certain points for himself,
that he may bring it to the class for the benefit of others.
(The following questions may have some value to the teacher in the
further study of the map, but should _by no means_ be used as a set form
or method of questioning. They are only suggestions, given to those who
may need them in assisting the pupil to think and reason for himself.)
His attention may be called to the triangular shape of the land mass,
with its greatest elevation in the west. He may be told that its length
is 5,700 and its greatest width 3,000 miles.
Questions may then be asked as follows: Into how many slopes or great
drainage systems is the continent divided? Into what ocean do the waters
of the long slope flow? Those of the short slope? Locate and give general
direction of the continental axis. Trace this from Behring Strait to
Isthmus of Panama.
Compare its length with greatest width of continent. Compare length of
long slope (2,200 miles) with length of short slope (500 to 700 miles).
Which slope has the longer coast-line? Mold in sand and chalk model,
showing the two slopes and continental axis. Compare surface of both
slopes. Which has the greater area of highlands? Which of plains? Give
number and comparative size of lakes. Compare length and direction of
rivers on each slope. What is the character of the coasts and harbors?
What of the islands? Which slope has the larger inland drainage system?
Compare with oceanic drainage system.
Locate highlands of each slope. Give the appearance of the Appalachian
Mountain System. Compare with the Rocky Mountain System. What can be
learned as to the general formation and altitude of each slope? (Show
typical pictures.) What is the effect of altitude upon the surrounding
country? What on drainage? What is the effect of large rivers upon
plateaus?
Locate great central valley of North America. What two great rivers flow
through this valley? Trace the Mississippi River from its source to its
mouth. Trace the Mackenzie River in the same way. What separates the
Mississippi basin from the Mackenzie basin? From the Saskatchawan basin?
Trace lowest line from the mouth of the Mississippi to the mouth of the
Mackenzie. Into what does this line divide the continent? (Into two land
masses.)
Compare these two. In which is the continental axis? (In the primary land
mass.) The secondary land mass is divided by the Appalachian Mountain
System into two slopes, of which the eastern is called the Atlantic
slope. Compare these slopes. Where do the Appalachian Mountains begin?
(In the St. Lawrence basin.) Nearly to what gulf do they extend? (Gulf
of Mexico.) What is their direction? What separates the secondary land
mass into two parts—northern and southern? (The St. Lawrence River.) The
northern part is the peninsula of Labrador. In this part trace the water
partings of the Hudson Bay river system.
In the primary land mass two immense mountain ranges extend over 5,000
miles—nearly the entire length of the continent. What are these mountains
called? Compare their general altitude with the low range of mountains
(100 feet high) crossing the Isthmus of Panama. How wide is this Isthmus?
(Fifty miles from coast to coast.)
What is known about a certain canal which has been begun in Panama? Is
there any other important canal in Central America?
Commencing in the southern part of Mexico, and extending northerly and
westerly, two great ranges bound the great plateau of Mexico on the east
and west. This plateau is divided by the Rio Grande, Colorado, and other
rivers, at a distance of about 500 miles north. The southern part of it
is a volcanic region, in which are Popocatapetl and other high mountains.
What can be told about the Colorado River? (Show pictures of structure,
also of ancient cliff dwellings.) What is the character of the rock
through which the river cuts? Is it in the region of much rainfall or of
no rainfall? North of the great plateau is the great basin, 600 miles
wide and 900 miles from north to south, enclosed by the Sierra Nevada,
Wasatch and Rocky Mountains.
What is the character of the large lake found here? Of what was it once
a part? (Tell of old Lake Bonneville, and the terraces which record the
height of its ancient waters, high up on the mountain sides, at the east
of Salt Lake. Show pictures of structure of country and the effect of
irrigation on the barren soil.)
What low range of mountains west of the Sierra Nevada range? Describe the
beautiful valley lying between these ranges. Why is it fertile? What are
its products? Describe the great red-wood trees.
What peninsula south of this is formed by the union of these two ranges?
Locate Mt. Shasta, 14,442 feet high, in the Cascade range (a part of
Sierra Nevada), just north of the California valley; also Mts. Tacoma,
Hood, and Ranier, in the same range. Find Mt. St. Elias, in Alaska—the
highest peak in North America, being 19,500 feet above sea level. (Show
pictures of these mountains. Tell stories of Alaskan Indians.)
Yellowstone Park is in the Rocky Mountain range, east and north of
Mt. Shasta. What do you know of this wonderful park? (Sketch geysers
of Yellowstone Park.) Can the prevailing wind of the Pacific slope be
confidently stated? What of the Atlantic slope? Compare the number and
character of rivers, also the coastal planes of these two slopes.
What relation has the structure of a region to the amount of rainfall?
Locate the region of greatest rainfall on the continent; also the region
of no rainfall, or desert region. Compare with the rainfall of the home
region. (Let the pupils chalk model the map again, showing the depressed
axis, great plateau and mountain ranges: also indicating the character
of coasts, whether high or low, and stating whether they are building or
wearing coasts, and why.)
Name the river basins of each slope. Locate the basin of the Mississippi
River, and trace its water partings. Give the general direction of the
river and the reason for its flowing in this direction.
What great rivers are in the right slope of this basin? Which is the
largest river? Why are the waters of the Missouri River colored? Which is
the largest river in the left slope? Compare the two slopes. Which is the
higher? Which has the greater number of river basins? Locate the Ozark
Mountains. Are there any lakes in this basin? In which course of the
river are the waterfalls or cascades found? (Show pictures of St. Anthony
and Minnehaha Falls.)
What is the length of the Mississippi River in a direct line? (1,275
miles, while the length by water way is 3,160 miles.) What is to be
inferred from these data as to the course of the river? What as to the
slope of the land and the character of the soil? What must be the effect
on navigation and commerce? In which course, upper, middle, or lower, are
most of the windings? (Tell of the levees built to prevent the river from
overflowing its banks.)
(The total length of the line of embankments, including those on both
sides of the river and its tributaries, is 42,500 miles.)
At what rate is the river lowering the continent? (Enough sediment is
annually carried down to cover twelve miles square of surface one foot
deep.)
Where is the soil being deposited? How far is the river navigable? What
canal is being dug to connect its waters with those of Lake Michigan?
Consider the effect of this great work on the commerce of Chicago. What
is the temperature in the northern part of the Mississippi River basin?
What is the character of its vegetation? Compare these with those of the
southern part. Where is the greatest rainfall? What besides fertile soil
and abundant rainfall, is necessary to insure luxuriant vegetation? Name
some fruits characteristic of the northern part of the basin, also of the
southern part.
Locate areas of land best adapted to the growing of food plants; as
grain, including rice; potatoes and sugar-cane; also those best for
grazing purposes; the raising of cattle, sheep, etc. What plants produce
materials for the manufacture of clothing? What areas are especially
suitable to the growth of cotton? What to the growth of flax and hemp?
Locate coal mines, and other mining districts; also lumber regions.
Where are the largest cities situated? Why are they thus located? What
localities are best adapted to manufacturing purposes? Which to commerce?
Interest the children in the discovery of the “great river.” Read
accounts of Joliet’s and Marquette’s discoveries in 1673, also LaSalle’s
discovery of its mouth in 1682.
Study the history of the early colonists and show the relation of their
environment to their social and political development.
The further study of history will require a constant review of the
geographical features of the continent, and will show their relation to
the political divisions. These may be marked off upon the map with red
chalk at the proper time.
In a similar manner each river basin of the continent may be studied
separately, and the Hudson Bay basin. Compare the Atlantic and the
Pacific, river basin systems, also Alabama and Texas systems of river
basins.
Review the whole continent. See where the boundaries of all natural
divisions coincide with the political divisions. Draw the continent,
and mark all the large political divisions on the map. Add, also, the
continental islands. How were these formed? What is a political division?
What is its use? Mention the government of each division of the continent.
As the study of other continents are taken up, they may be compared with
this one, and with each other, in regard to resemblances and differences.
[Illustration: 61]
MAP OF NORTH AMERICA.
It is supposed that in the course of their study, the pupils have been
in the habit of modeling in sand and chalk modeling on the blackboard
at every step of the way. It may now be found that they are prepared
to represent the entire continent, first in two slopes, again in land
masses, and then as an aggregation of river basins, as suggested in the
last lesson.
Such a development of the map is illustrated in the present lesson by
four stages of chalk modeling. The first stage is represented in Fig. 61.
It shows the continent of North America in two great slopes, one long one
sloping to the east, and a short one sloping to the west, from the line
of meeting of their upper edges, or what has been termed the Continental
Axis.
Fig. 62 represents the continent as sketched after a study of it as
simple land masses—a primary land mass, and a secondary land mass, with
the line of depression at the meeting of the two opposing slopes. This
line is indicated by lines slanting downwards towards the depressed axis.
[Illustration: 62]
The primary land mass is represented as one continuous unbroken land
mass extending from the Isthmus of Panama to Behring Strait, and is
itself divided into two main slopes. The secondary land mass is likewise
divided into two slopes; it is also separated by the St. Lawrence River
basin into two parts, _viz._, the northern or Labrador land mass, and
the southern or Appalachian land mass. Fig. 63 is drawn to represent the
drainage, or principal river basins; as, the Mississippi, Mackenzie, St.
Lawrence, and Saskatchawan basins, and the Hudson Bay river system. In
drawing small maps on paper it is necessary to trace the rivers with a
fine pencil point. For very large maps, four of five feet long, spaces
may be left, but great care should be taken to keep them as narrow as
possible, so as not to exaggerate the width of the rivers more than
is necessary. Fig. 64 is drawn in more detail and the great political
divisions are marked upon it. On the blackboard map these divisions
may be marked with colored chalk, and should follow the contour of the
surface as closely as possible.
For the teacher who wishes to rapidly chalk model a map for immediate use
in the class, the following hints may be of service:
Plan to draw the continent in its proper proportions within a given
space. Imagine that you see it as already drawn. Commence with the
region best known or understood, and draw as you mentally travel, to the
north, south, east or west. It may be that you will begin with the great
depressed regions, in which case draw the ascending slopes and crowning
altitudes as you mentally picture; or if the great highlands or water
partings are fixed upon as a starting-point, the descending slopes should
be drawn to the line of meeting of other slopes, or to the sea level.
Break the line to indicate broken or uneven surface. You will do this
naturally, however, if you have in mind the picture of a broken surface.
[Illustration: 63]
Keep the river basins definitely in mind, and the character of streams
and rivers: the character also of the land structure; whether it is rocky
or alluvial; sharp or hard, or soft and yielding. Knowing that line
represents direction, and having a clear and distinct picture in mind of
the real country with its surface features, it will be an easy matter
to draw or represent it. Understand, as has often been said, that the
delineator is drawing from his own mental image of a map, and not copying
the work of another. In the latter case no instructions are necessary,
as the practice is of no educative value, and should be persistently
discouraged.
While at work, always think of the continent as being lighted from
one direction, so as to show strong lights and shadows (utilize the
blackboard for shadows), this helps to show altitudes; bear in mind,
however, that these depend mainly upon direction of line corresponding to
direction of surface.
It is to be remembered also, that knowing the geological structure
prevents one from drawing level lands first, and from afterward
delineating mountains as being piled upon them. Mountains should be drawn
where they belong and valleys where they belong, with no contradictory
lines underneath to confuse the meaning.
With few exceptions, mountains are the crowning points or peaks of
slopes—their meeting place. They may be the corrugated points of mountain
ranges or of worn down plateaus.
From whatever part of the continent the work is commenced, let it be
carried out in every direction until the limit of land is reached, and
then stop. Remember that there is no line between land and water, either
at sea-shore or at lake-shore. The rivers may be drawn with charcoal,
accentuating the lower part of the river near its mouth.
[Illustration: 64]
Let me say to the beginner—do not let any crude results disturb or
discourage you. You can chalk model with an adequate amount of skill if
you will. It simply means a close study of nature, a clear knowledge of
geographical structure, and persistent effort.
[Illustration: 65 66 67 68]
NATURAL FEATURES OF INTEREST IN NORTH AMERICA.
It is the constant, persevering attempts—simply the continual doing—that
accomplishes the work of the world. Devote ten minutes a day, if you
cannot spare more time, to your preparation for sketching in to-morrow’s
classes. By expressing your mental picture again and again you clear it
up, and the increased interest of your pupils in the work will be ample
reward. The experience gained will probably show that your last attempt
is a much more complete expression than the first one; the repeated
efforts made having resulted in a more thorough knowledge of the subject
and therefore, a more complete representation.
As before stated in connection with the study of North America, natural
features of interest should be sketched while with the class, at the same
time locating them on the map.
The mental images for such sketches, as well as for all others, if not
gained by actual observations, must be acquired through the study of
pictures and descriptions, as has been remarked before, and should not be
copied line for line from another’s sketch.
[Illustration: 69 70 71 72 73]
In Fig. 65 (entrance to Mammoth Cave, Kentucky) the stratification of the
rocks is seen back of the entrance, within it, and at the right in the
rocks of the foreground. (It is estimated that 12,000,000 cubic yards
of limestone have been worn away or displaced in the excavation of the
interior of this celebrated cave.)
Fig. 66 (Natural Bridge, Virginia) also plainly shows the stratification
of rock. What is the character of the rock? What was the agency employed
in the sculpturing of both of these natural wonders?
In Fig. 67 (Niagara Falls) the general direction of the mass is oblique.
Notice how the water breaks as it falls, owing to the resistance of
the atmosphere. In the “Palisades on the Hudson” (Fig. 68) notice the
debris at the foot of the vertical wall of stone, forming what is called
the talus slope. This is mostly overgrown with vegetation. In Fig. 69
(a gorge in the cañon of the Colorado) the stratification of rock and
the almost vertical cliffs are the principal features illustrated. Fig.
70 represents a lofty peak in one of the cañons along the line of the
Colorado. Fig. 71 (Devil’s Slide, Weber Cañon, Utah) shows the mountain
side as worn back leaving the trap rock projecting. (How came the harder
rock there in this peculiar shape?) Figs. 72 and 73 are geysers in
Yellowstone Park—“Old Faithful” and “the Sponge.” In the latter, notice
the corrugated formation, and the little stream that flows from its base.
[Illustration]
MAP OF MEXICO WITH SUGGESTIONS FOR FIFTH AND SIXTH GRADE TEACHERS.
In the study of political divisions, details of structure, climate, etc.,
that were not brought out in the work on the continent as a whole, should
precede the historical study.
Again let it be stated, that the method and questions here given are not
to be followed literally; they are merely presented as suggestive hints
to teachers, who should frame their own questions so as to best lead the
pupil in his study to a realization of what the country is in itself,
and how geographical conditions affect the history and civilization of a
people.
Having a general idea of the geographical features of Mexico, the pupil
in its closer study, may give its location as lying south of the United
States and extending from Texas on the north to central America on the
south. He may describe its general shape as triangular or cornucopia
shaped. He may notice that the Rio Grande forms its natural boundary on
the north, for nearly three fourths of the distance from gulf to ocean.
What is the length of this river? Compare with length of the Mississippi.
How far is it navigable? (About 500 miles.) What is its character?
(Swift, crooked, and obstructed by rapids and sand-bars.) Notice the
break in the great western range of mountains, forming a depression
between the Sierra Madre and Sierra Nevada Ranges.
Just north of this break and west of the Colorado River, in the state of
California, lies the great Mohave Desert, in which is the famous “Death
Valley,” 100 feet below the level of the sea.
From the Gulf of Mexico on the east and the Pacific Ocean on the west
the land rises in a succession of terraces or plateaus, with elevations
varying from 2,000 feet to 8,000 feet above sea-level.
The great central or upper plateau has an elevation of about 3,000 feet
at the north, but ascends gradually to the height of 8,000 feet in the
southern part. Compare this with the Mohave Desert. With the great
plateau of the United States. With Florida (mean elevation 30 feet). In
this part, the eastern mountain wall of the great central plateau, and
the western, which is much higher of the two, culminate in a knot of
lofty mountains. This is a volcanic region, and here a number of isolated
volcanoes tower above the uplands in a line from east to west. Of these
snow-capped volcanoes the highest are Popocatapetl and Orizaba, which are
about 17,500 feet above the sea-level.
Compare these with the highest peaks of the Rockies. From this point the
land abruptly lowers to the low Isthmus of Tehuantepec and the Peninsula
of Yucatan. Mexico has an area of 744,000 square miles. Compare with area
of the United States (3,605,000).
Why are there more rivers flowing into the Gulf of Mexico than into the
Pacific Ocean? Where is the greatest rainfall? What is the direction of
the prevailing wind? Can this be known from the map? The average annual
rainfall at the Gulf Coast is 150 inches. How does this compare with
that of Florida? (60 inches.) With that of Chicago? (36 inches.) What is
the rainfall on the western coast? (There is scarcely no rain at all.)
Why? Where is the source of the rivers on the west coast? The average
rainfall of the plateau is 27 inches. May we expect to find many rivers
flowing from it? What is likely to be the character of rivers flowing
into the Gulf? (They are swift torrents bearing trees and rocks, tearing
and cutting gorges and cañons from 800 to 1,000 feet deep.) Compare
these with rivers of the Atlantic Coast. How are the sand-bars at the
mouths of the rivers on the eastern coast to be accounted for? What
effect must they have upon commerce? What may we conclude as to the
character of Mexican harbors? Would the water-ways afford an enemy means
of transportation to the heart of the country? May we conclude that the
natural structure of the country affords protection from enemies? What
influence has this isolation had upon the progress of the people? Has
Mexico a navy? Why not?
Mexico has two seasons—the dry season and the rainy season. The latter
begins in June and lasts until October. What is the prevailing wind in
each season? What influence has altitude upon climate? Mexico has three
zones of climate, according to altitude. The mean temperature of the low
lying coast zone or “Hot Lands” is 77 to 82 degrees Fah. at Acapulco on
the western coast. What is the climate? (Hot or dry.) What is the climate
on the eastern or Gulf coast, where the mean temperature is 77 degrees
Fah. rising at Vera Cruz sometimes to 110 degrees Fah.? (Hot, humid and
unhealthy. In the rainy season the land is partly under water—steaming.
In the dry season the ground is parched and the air oven-like.) What is
the character of vegetation, birds, and animals? Compare vegetation with
that of cold or cool regions as to appearance, kinds of trees, etc., and
its value or usefulness to animals and man. Which city would be the most
desirable for a home?
What must be the natural effect of the existing structure and climatic
conditions upon the inhabitants of these areas? What kind of houses would
they be apt to build? Draw type of houses with environment. The plains
rise from the coast gradually to the height of about 2,000 feet where the
hills begin, and above these we find other plains.
How does this altitude affect the climate? Vast herds of cattle, horses
and sheep roam these plains, and well stocked ranches are in the northern
part. Agriculture is the chief occupation in the southern part. The soil
being largely volcanic is extremely fertile when irrigated. From the
height of 2,000 feet to about 7,000 feet we find the “Temperate Lands.”
These combine the conditions of two zones. The heat and moisture of the
“Hot Lands” uniting with the cooler breezes of the uplands, produces one
of the most equable and delightful climates in the world.
The mean temperature is from 62 to 70 degrees Fah. Compare this with the
mean temperature of Chicago. The heaviest annual rainfall recorded is 90
inches. Air-plants and creeping vines are everywhere. Flowers are more
delicately fragrant, birds are songsters, and insects are fewer than in
the lower hot lands.
Tropical products are found at a height of 4,000 feet. Rice, coffee,
sugar-cane, tobacco and fruits like olives, oranges and lemons are all
found here.
Evergreens, oaks and cedars are here as well, while maize and beans are
seen growing all the way up from the coast.
Grains grow best at a height of 6,000 feet. Compare these conditions with
those of the Hot Lands. Would the temperate lands be a desirable place
for a home? What effect has the climate upon the people? Compare them
with inhabitants of the low lands. Draw typical scenes, including houses,
of temperate lands.
About 7,000 feet we find the “Cold Lands.” Here the amount of rainfall is
only one-sixth of that of the low lands. Many small rivers having their
source in the eternal snows of the lofty mountain peaks, disappear before
reaching the lakes or lagoons. Why? Above 8,000 feet many varieties of
the fir tree are seen climbing the mountain slopes. Only four mountain
peaks are snow-capped all the year round.
The mountains are rich in metals, especially silver. Sulphur is obtained
from the very throat of the crater of Popocatapetl. Salt is obtained
from the lakes. The pupils should chalk model the plateau of Mexico
showing what they have learned of details of structure. On this plateau
every variety of surface is seen. Here are deserts, wooded hills, quiet
valleys, and broad level plains studded with clear sparkling lakes which
have no visible outlets. What feeds these lakes? What is their character?
(Saline.) Why are they salt? Are they getting larger or smaller? Why?
Compare the surface here described with that of Yucatan.
The soil of the latter is largely limestone. The surface is low and
monotonous, with scarcely a river or brook of any considerable size.
Midway between Vera Cruz on the Gulf coast and Acapulco on the Pacific
in the valley or basin of Anahuac, on a plateau of the interior, is
situated the renowned city of Mexico, at an altitude of about 7,800 feet
above sea-level. In which climate zone is it located? The valley is about
55 miles long, and 30 miles wide, and is hemmed in by mountains with the
great volcanoes to the southeast.
Higher than any other, and the first to attract the traveler’s eye as he
enters the valley, is the mighty Popocatapetl.
In the northern half of the valley are three small lakes and a number of
towns and villages. In the southern half there are three large lakes and
the city of Mexico. The lowest part of the basin is Lake Tezcuco. This
is only 6 feet below the level of the plateau on which the city stands.
The waters of this lake are salt, while Lake Xochimilco is a fresh water
lake, situated a few miles south of the city and is 4 feet higher. It is
from this lake that the city of Mexico obtains its water supply. What is
the population of the city? What do you know of its people?
Throughout the lessons the pupil should be continually led to imagine
what the life of the people must be, from what is known of their
environment. Lead him also to infer the reasons for their present
state of advancement in civilization. Have him sketch scenery, houses,
utensils, etc., illustrative of their modes of life.
Show pictures of ancient Aztec and Toltec ruins. Tell of the people who
came from the north and settled in the marsh near Lake Tezcuco.
Speak of their great works—temples, aqueducts, dykes and causeways. Refer
to evidences of culture as shown in ruins of buildings, fountains, baths,
tapestries, etc. What was their religion? Compare them with the Indians
of northern forest regions.
What were the motives of the Spaniards in the conquest of Mexico?
Describe the landing of Cortez and his army and let the pupil infer the
difficulties and dangers encountered on their way into the country; the
hot climate, shifting sands, tropical marshes, slippery precipices,
gorges with swollen streams, and the mountains to be crossed. Through
a pass they went in single file into a sterile region where there was
no water: through a second defile, a valley, and then another and more
difficult gorge until the summit reached, they descended into the
interior valleys. Here the Spaniards rested for four days, near the
desert infested with wolves and other wild animals. Tell of Cortez’
attack on the great city—his repulse—the siege, etc. Show that the
results were largely determined by the geography of the country.
Cortez conquered because the country being broken up by mountains,
plateaus and valleys naturally divided the people into many small tribes,
some speaking different languages, who were under forced subjection to a
federation consisting of warrior bandits from the stronger cities.
Give the result of the conquest to the Mexicans, and bring their history
down to the present day if desired.
What class of people now inhabit Mexico? What regions are most densely
populated? What is the population? Compare with the population of the
United States.
What is the form of government? Where are the largest cities? Where the
greatest seaports? Describe the modifications of surface structure since
the conquest. (Lake Tezcuco has receded from the city two and one half
miles. How?) Tell of the floating gardens.
[Illustration: 74 75 76 77 78]
The page of illustrations accompanying the above suggestions include the
Map of Mexico, Fig. 74, and also a section of the map, Fig. 75, showing
more plainly the old valley of Anahuac, and Lake Tezcuco. Figs. 76 to 78
are scenes typical of the country.
MAP OF SECTION OF THE UNITED STATES, FOR USE IN PREPARATORY LESSONS ON
THE CIVIL WAR.
The section under consideration lies east of the Mississippi, and south
of the Ohio and Potomac Rivers.
The motive for its study is to trace the influence of physical
environment upon the character and motives of the inhabitants.
The following plan for the lesson is suggested:
1. _Description of Country._ (_a_) character; (_b_) altitude; (_c_)
vegetation; (_d_) productions.
2. _Division into Belts._ (_a_) mountainous; (_b_) hilly or plateaus;
(_c_) lowlands.
3. _Interests of the People in these Sections to be Subserved._ (_a_)
Protection of homes; (_b_) railroads; (_c_) factories and cattle; (_d_)
open navigation; (_e_) non-interruption of labor.
4. _Plans of Attack by the Enemy._ (_a_) To gain a stronghold in the
mountains; (_b_) destroy railroads; (_c_) obstruct rivers; (_d_) capture
cattle; (_e_) devastate the fields.
[Illustration: 79]
Locate on the map of the United States the special section of country
to be studied, and chalk model in detail large map of the same. (See
Fig. 79.) From this map, together with typical pictures of scenery,
_i.e._, mountains, rivers, valleys, vegetation, industries, etc., the
pupil may imagine the general character of the land. What will be his
mental picture? (A rolling country, broken into hills and valleys, with
mountains more or less rounded and generally clothed with vegetation.)
Passing downwards from the heights, the surface becomes more gently
undulating and finally stretches away in long level fields.
The pupil may imagine what might be seen from a great height south of
the whole section. Immediately below is the sea. Florida at the right,
low and green, widens into the mainland in front. The sandy gulf shores
broken by many rivers and blending into light greens, darken and turn
into browns in the mountains. Lines of grays and purples in the distance
indicate the farther mountain ranges. The gentle western slope, and the
more abrupt eastern one are clothed with rich foliage, through which
gleam the waters of many rivers.
What is the trend of the mountain ranges? (From northeast to southwest.
Three nearly parallel ranges are seen with long valleys between.) Which
is the most important one? What is the whole mountain system called? (The
Appalachian System.) Give the names by which the principal ridges are
known. Where is the greatest height? (In North Carolina—Mt. Mitchell,
6,710 feet high. From this point the mountains lower gradually to the
north, being in Pennsylvania from about 1,000 feet to 1,500 feet in
height. To the south they drop more rapidly, through Georgia and Alabama.)
Are there any natural divisions in the eastern slope? (The mountains,
piedmont, and tide-water regions. The piedmont or old plateau region is
hilly, while the tide-water region, having been built by the rivers,
is low and near the coast often swampy and unhealthy. The rivers are
numerous, forming low islands at their mouths.) What are the divisions of
the western slope? (Mountains, plateaus and valley country. The plateaus
are long arms of high land stretching out from the mountains, under the
names of the Cumberland and Tennessee. Rivers have cut into the plateaus
which gradually widen into the Ohio and Mississippi.) What is the nature
of the soil? (Rich, low and level, adapted to the raising of cotton. Near
the Mississippi the land is often swampy and covered with a dense rank
growth of vegetation. The strong current of the river often changes the
course of its channel, thus forming the numerous bayous or long narrow
lakes found in Arkansas, Louisiana and Mississippi.)
What is the vegetation of the mountain regions? (Wooded with pine, oak
and other mountain trees.) What would be the chief products of this
region? How could the lumber be gotten out of the country? (Tell of
mines.) (Slightly wooded and richly turfed would describe the middle
section.) What would be the chief occupations of the people? (Farming and
stock-raising. In the low valley country the products are tobacco, sugar,
rice and cotton.)
At the time of the Civil War, what were the chief interests of
the mountain people? (In consequence of their industries they had
comparatively slight interest in the questions of slavery.)
Their knowledge of passes, cross-roads, sites for forts, etc., would make
them invaluable aids to either party. Of what value might the possession
of any special point be to either side during the war? (It might be used
as a fort or arsenal. To the opposing side it might prove an entering
wedge by which other points might be gained and so divide the people.)
What would be the interest of the miners? (They would favor peace for the
sake of uninterrupted labor. If by war their work should be stopped their
families would be reduced to starvation.)
Near the mines would be found railroads. What would be the policy of the
South in regard to them? (To protect them for their own use.) That of the
North? (Destruction or possession.) What would be the farmer’s interest?
(The protection of stock and farm products.)
In the lowland section the protection of railroads would be one interest.
What other interests would be endangered by war? (Vast fields of cotton
and other southern products would be subject to trampling or burning;
fences, houses and other buildings likely to be destroyed. The desertion
of slaves would leave fields uncultivated, want in the houses and homes
unprotected.)
If crops could be raised and gathered, what of their disposal? (The
market would be smaller, their delivery uncertain. Blockaded rivers and
deserted railroads are obstacles to commerce.)
What points would be desirable to gain against the South? (_a_) (A
foothold in the mountains and control of the railroads leading thereto;
(_b_) Possession of boats to be used on the Mississippi in closing ports
and the holding of them; (_c_) Occupation of a line of points on the
Tennessee or the Cumberland River, and so push the northern line farther
down; (_d_) Possession of seaports along the Atlantic coast.)
What could be planned for the opposite side? (_a_) (To gain possession
of Washington; (_b_) To fortify the northern boundary of the Confederacy;
(_c_) To protect the Mississippi River and the coast.) Read extracts from
war letters of Grant, McClellan and others to show the relation of the
plans of the generals to the geography of the country.
MAP OF SOUTH AMERICA.
To repeat what has been said in substance again and again, in the course
of these lessons (it cannot be too often brought to mind), if you know
your subject, _i.e._, have the knowledge, and desire to give it to others
you will be able to do so; more or less crudely it may be, but one learns
to do, only by doing.
Should you be in doubt as to the direction of line to use, analyze the
gestures you would naturally make in an oral expression of the same
subject, and see just what direction you wish to represent.
Do not misunderstand in regard to the representations of elevations on
the map. These are not drawn to represent actual shape, any more than
actual size or height; they merely indicate location.
The horizontal distances of the map should never be compared with the
altitudes, but compare altitudes with altitudes, and horizontal distance
with horizontal distance. Lead the pupil also to continually compare
the altitudes given, with those within his sense grasp; _e.g._, Mt.
Chimborazo is about 20,500 feet in height. What is the height of the
highest building, hill or mountain the pupil has ever seen? How many such
elevations placed one above another would equal the height of Chimborazo?
By such comparison the pupil will be in no danger of getting a wrong idea
of the altitude from the study of the maps. Horizontal distances may be
compared in the same way. A given distance of thousands of miles may be
compared with a shorter distance within the experience of the pupil.
[Illustration: MAP OF SOUTH AMERICA]
Remember this method of drawing or chalk modeling is designed chiefly to
suggest to the mind the main characteristic features of the continent.
To those who have read Lessons VIII. and IX. it is scarcely necessary
to illustrate the four stages in the map of South America or other
continents.
Notice that the land lowers towards the north in Peru and Bolivia and
also from the Guiana highlands. Get the effect by reducing the size of
the hills and mountains as they recede, and by making them less definite.
[Illustration: 80]
MAP OF EURASIA WITH SECTIONS IN DETAIL.
Your pupils may soon excel their teacher in chalk modeling. This is
encouraging. The true teacher will rejoice at such proofs of success in
instruction and be stimulated to renewed endeavors.
It is of such vital importance that pupils acquire the habit of
expression through drawing. Fig. 80 is a map of “Eurasia” or Europe and
Asia together as one continent. It shows the highlands which divide the
waters of the northern or long slope, from those of the short slope,
i.e., the backbone of the continent or continental axis. About midway
between the extreme eastern and western coasts, note the high plateau
or center from which many mountain ranges radiate—the Pamir or “Roof of
the World” 15,000 feet in height. The plateau of Thibet is also 15,000
feet high, but towering above these are many lofty mountain peaks, some
reaching the height of 25,000 to 29,000 feet.
From these plateaus, those of Gobi and Iran, and the highlands in Europe,
the land lowers more or less abruptly as it recedes to the north, east
and south. To represent the Arctic coast, where the land is mostly low,
draw with the horizontal stroke. Between this and the highlands use
broken horizontal or slightly curved lines to indicate the broken hilly
surface. Be careful to keep the great depressions level around the Black,
the Caspian and Aral Seas.
[Illustration: 81 82 83 84 85 86]
[Illustration: 87 88 89 90 91]
The Scandinavian Peninsula (Fig. 81) is drawn more in detail to show the
fiord coast.
Fig. 82 is a typical view of the coast. A map of India, with the Himalaya
Mountains on the north, and the Hindu Kush Mountains on the west, is
seen in Fig. 83. Notice the source of its three great rivers. Fig. 84
is a typical view on the Bramahpootra River. Fig. 85 is a map of Greece
and Fig. 86 a view of the country immediately surrounding the Acropolis.
Figs. 87-91 are a map of Japan and typical scenes illustrative of the
country, houses, and costumes of the people.

REVIEW OF INSTRUCTIONS. MAPS OF AFRICA AND AUSTRALIA.
In reviewing the directions for chalk modeling, the following points are
noted, (_a_) A mental picture made clearer by expression; (_b_) A desire
to express through the medium of chalk and blackboard; (_c_) Analysis
into terms of drawing, as masses and sub-masses, direction of line,
light and shade; (_d_) Quality of line, attained through “feeling” or
harmony with the subject; (_e_) Artistic expression (no modifications, as
erasures or additions); (_f_) Persistent effort.
Through the observance of the hints given on these points adequate skill
in execution may be acquired.
The plateaus of Africa and Australia are classed together in this lesson.
Little is known of the western half of the latter, but the eastern half
of Australia has its rivers and river basins.
We see also how it has been worn into mountain ranges; the highest part
being in the southeast. Africa is also wearing back from the coasts and
the plateau itself has many long river basins, the longest of which is
that of the Nile. The Nile is not only the longest river in Africa but is
the third river of the globe as to length. The valleys of the continent
are mostly very narrow, especially the valleys of this river.
[Illustration]
The Sahara Desert is represented as being broken into a number of
plateaus and depressed regions, which is expressed by short, nearly
horizontal lines.
The Abyssinian Plateau is given in detail in Fig. 92. Notice that it
lowers gradually towards the south, but abruptly towards the north and
that its surface is broken into many plateaus and deeply cut river beds
by tributaries to the Nile.

ADVERTISEMENTS
CHALK-MODELING.
_Relief maps_ or representation of relief maps are absolutely essential
to the intelligent teaching of geography. The most effective means that I
have seen employed for the production of such maps is the chalk-modeling
so long and successfully taught by MISS IDA C. HEFFRON. I can think
of no other contribution to present text-books which would be of so
great service to the teachers as a book from which they may learn
chalk-modeling, to the end that any portion of a continent or country may
be placed in relief before the eyes of the children on whatever scale the
teacher desires.
I have known MISS HEFFRON’S work for the last fifteen years and commend
it without reserve.
O. T. BRIGHT, _Chicago, Ill._
It gives me great pleasure to commend MISS HEFFRON’S work to the
attention of school officers, and to school teachers who desire
assistance along the lines of expression in school work. Her large
practical experience in teaching children in all the grades of public
school work, furnishes a substantial basis for most excellent instruction
in her chosen field.
Whatever success may have attended the introduction of Nature Study
into this school has been largely due to her intelligence and skill in
directing the work in drawing, painting and modeling.
WILBUR S. JACKMAN, _Teacher of Natural Science,
Cook County Normal School_.
The value of Drawing and Modeling as modes of expression cannot be
over-estimated. Every subject taught in our schools gains new power and
life, as the brush or pencil, the clay or tool, tells its own truth
concerning it. Literature, History, Science and Geography gain an
immensely added value: each one becomes a living thing if the teacher
possess the power to illustrate her subject. In Geography especially,
the Chalk-Modeling originated by MISS HEFFRON, while teacher of Drawing
in the Cook County Normal School, is of incalculable value. In fact, to
those in whose schools it has been introduced, the wonder is that pupils
ever comprehend the subject without its revealing and interpreting aid.
KATE STARR KELLOGG, _Prin. of Lewis School, Englewood, Ill._
I have seen the results of MISS IDA CASSA HEFFRON’S work in teaching
Drawing, Painting, Modeling and Illustrative Drawing, and Chalk-Modeling
in Structural Geography, and I consider her work of the highest
importance. It gives to training teachers, and teachers of general
experience as well, a newer and deeper insight into the truth that
Drawing with its allied subjects is a form of expression.
