Title: A Great Globe Author: Elisée Reclus Date: 1898 Language: en Topics: geography Source: The Geographical Journal, Vol. 12, No. 4 (Oct., 1898), pp. 401-406 Notes: Paper read at the Royal Geographical Society, June 27, 1898. Before the reading of the paper, the PRESIDENT said: We have with us this evening one of the most celebrated and eminent geographers now living, M. Elisee Reclus. He has come amongst us to give us his views respecting the use of globes. I now request M. Reclus to read his paper. After the reading of the paper, the PRESIDENT said: I have no doubt several geographers will wish to discuss this extremely important paper which M. Reclus has just read to us.
RECENTLY being in conversation here in London with a traveller and
discoverer, I mentioned the great geographical importance of accurate
representations of our planet in the shape of globes; suddenly he
interrupted me, and said with a smile, "What is the use of your
Lilliputian globes, ten, a hundred, or a thousand yards thick, when you
have the very globe itself, our good and beneficent Earth, to walk over,
to look at, to study, and to love?" Of course I laughed, and thought
with him that all representations and symbols of life are very little in
comparison with life itself: our works are small when contrasted with
nature. But the great man who thus spoke in joke knew as well as I do,
the value of scrupulous effects in geographical work. He has himself
drawn very useful maps, which enable us to follow him in his great
travels. We cannot all perambulate the surface of our planet, but we may
still be very useful in a secondary way. The great question is to know
in what direction we are to exert ourselves in order to produce the
greatest amount of perfect scientific labour. The chosen few will make
discoveries; the others, less fortunate, but happy still, will follow in
the track opened to them.
One of our eminent geographers, who is present at this meeting, Dr. Hugh
Robert Mill, gave us, a few years ago, a lecture on the "Geographical
Work of the Future," and put great stress on this, that " accurate
cartographic representation is the very essence of geography." Certainly
he was right. Accuracy of design is of paramount importance, and this is
the reason why geodesists measure the surface of the Earth with such
wonderful care and precision: a difference of a few millimetres on two
measurements of a line of base is justly a great matter of discussion,
and obliges the scientific bodies to begin the work again. Thus a
perfect exactitude is obtained in geodetic calculations, and the real
distances and proportions of all geographical features are triumphantly
made out; but the results, although fulfilling all expectations and
perfect in registers and tables, are in a certain measure practically
lost on the deceitful maps and charts: there truthful representation is
quite out of the question, at least for all parts of the figure which
are not delineated on the centre of the map. A plane surface never will
nor can be the real representation of a spherical surface. Splendid
devices may be imagined by the mathematicians to lessen the importance
of errors according to this or that dimension of the map, but although I
do not deny the immense conveniency of maps, without which there would
be no geography at all, still we may point out the errors which will
subsist, and sometimes we feel tempted to ask, "What's the use of having
secured perfect accuracy in measurement, within one millimetre, when on
paper the errors must amount to yards, furlongs, and miles?"
There is only one way to represent truly the surface of the Earth.
Curves are to be translated in curves; a sphere or fragment of a sphere
must be reproduced by another sphere or fragment of sphere. Therefore
are we really astonished that public attention and the special care of
geographers are so little attracted towards this logical mode of
geographical work.
The progress of cartography proper has been really immense. When we
compare the maps and charts which are now constructed by the various
industrial, maritime, and military staffs with the very interesting maps
of the last century, which had been also constructed with great care by
the best geographers and at very great expense, we are struck by the
marvellous increase of those documents, not only in quantity, but also
in quality. I may say that certain maps, where the scale is very large,
and which, in fact, may be considered part of an immense globe, are at
the same time so gloriously embellished by colours and graduated tints
that they are really wonderful to look at, both as true representations
of nature and as marvellous works of art. The impression which genuine
geographers feel is very near or even entirely similar to that of an
artist before a glorious picture or statue. To see nature itself, and to
behold at the same time a picture of it in perfect accordance with the
reality, is positively a rapture. As examples, there are the official
maps of Switzerland or the Bay of Naples.
But, returning to sphaerography, we must avow that there are very few
globes or segments of globes which have been made with sufficient care
to be held in comparison with the best charts. Generally they are much
less scrupulously drawn, being constructed more for show than for
science; they are less worthy of attention. Of course, some of the
elaborate globes which have been issued by various publishers are
altogether very creditable objects, but few are to be studied with the
same confidence as maps in almost all civilized countries. Some of the
globes which have been constructed are huge in dimensions. There is one
cut in a rock, I believe, on the seashore near Bournemouth, but I don't
know if it has any real value. There was one at the last Paris
Exhibition which was some 120 feet in circumference, being one-millionth
of the mother Earth to scale, and I must say this gigantic globe has
left on minds of the three hundred thousand people who saw it a very
deep impression, by the mere comparison of dry land and sea, and the
large proportions of countries which are ordinarily shown in Lilliputian
forms in most atlases. I remember, also, the real feeling of rapture
which pervaded me when, in my youth, I walked inside of Wylde's globe,
near this very place, admiring the magnificent sight. But that noble
structure, as well as the Paris Exhibition globe, made no pretence to
accuracy in geography proper; they had been designed only to be looked
at from afar, without any special study of minor details.
The Paris globe was to be seen from the outside, on a winding staircase;
the London Wylde's globe, forgotten now by our contemporaries, was seen
from the inside, and was to be contemplated at one circular glance.
According to Alfred Russel Wallace, whose opinion has such great weight,
the last method would be really the best.
I repeat it again, this department of geography, sphaerography, although
the most important to develop, has not kept pace with the other,
cartography, and I presume it will be a real revolution when it has
taken in science and practice the paramount place it deserves. At
present small globes are very much in use for schools, but we know how
that- part of the educational furniture is shamefully neglected; the
very fact that it is found in elementary classes is one cause of the
disdain in which globes are generally held. There is, perhaps, another
reason. Globes of large proportions are very cumbrous objects, and in
our crowded cities, where space is so expensive, it is very difficult to
find place for these scientific guests. And, above all, the best of
reasons is that education has not been yet directed in that way, and
people, even scientific people, are not yet sufficiently convinced of
the absolute necessity there is to study geography on images of our
planet reduced to a commodious scale and with the real proportions.
There is no geographer, however learned and accustomed to the reading of
maps, who is not constantly at a loss to understand immediately, at the
sight of charts drawn on all kinds of scales, what exact proportions the
country represented bears to his own land or district. He will not see
the real state of things; he will try to remember the figures he has
learnt by heart, or make tedious calculations, which are a great loss of
time.
So it is that for us all, learned or unlearned, the direct study of
geography on spherical surfaces is absolutely necessary. If the scale of
the globe is very small in comparison to the real dimensions; if it is,
for example, in the proportion of only one to 10 or 20 million, then the
surface is to be kept even—polished, we may say—because the roughness of
the highlands and mountains cannot be represented with sufficient
relief. On such a ball, 6 or 12 feet in circumference, the highest
mountain of Himalaya would not represent 1/25th of an inch in height,
and the ordinary hills would hardly alter the regular surface of the
globe. But, with larger spheres or fragments of spheres, another element
of truth and beauty is added to the construction; the actual relief
appears on the curvature of the model.
And here allow me to say, once for all, that the system of exaggerating
the proportional height of hills and mountains on the surface of globes
is utterly bad, contrary to real science, and ought to be discouraged by
all geographers respectful of nature and its laws. In that way the
utmost ugliness is attained; people who do that kind of work seem to
think themselves above all sense of reality. Thus we hear that the
ladies of the Philippine islands, wishing to make a valuable present,
imagined to have a representation of their archipelago made by a
jeweller with rubies for the cities, sapphires for lakes, and other
costly stones for volcanoes. Of course, many thousand pounds were
expended for that miserable rubbish.
All the pseudo-relief maps which show us slopes with two, three, fifty,
one hundred times their real proportions in height, inconsistent with
the facts, and violating the forces of gravitation, are the logical
consequence of a childish desire to represent grand sights as if they
were always stupendous, wonderful, next to miraculous. It is in the same
spirit that, during the first part of this century, before the invention
of photography, painters were prone to exaggerate in their pictures
twice, or even three times, the real proportions of mountains in
altitude; conscious in a certain measure of the deficiency of their art,
they relied on falsehood to make it more eloquent. Happily, new
discoveries have enrolled the sure, the victorious light of the sun on
the side of truth, and now we have by thousands and by millions splendid
pictures of mountains, which give to our eyes the true sense of
proportion, and certainly do not diminish our conception of beauty.
The revolution which photography has accomplished in pictorial art is to
be achieved also in relief construction. We are to be most strict in one
thing—keep always to the truth. It is the best plan in scientific work
as in life. Truth in scales: therefore it is that we must use globes
instead of maps as frequently as possible. Truth in heights of relief:
therefore do we leave entirely out of question the idea of showing any
apparent roughness on globes or fragments of globes under the scale of
one-millionth. On such balls colours and shades only will be convenient
to represent the various altitudes on the Earth and depths in the sea.
But as soon as the globe or fragment of globe is large enough to show at
least one-millionth part of the Earth in real proportions, then we may
try to represent as well the heights and depths as the planimetric
dimensions. Of course, the chiselling and moulding of the surface will
be more and more elaborate in proportion to the increase of the scale.
On a globe of one-millionth, the great masses of highlands and
mountains, 3000 feet in height, will hardly appear above the plains, and
only by the contrast of light and shade; but summits of 10,000 or 12,000
feet will be seen perfectly well-the more so, that to show forests,
pastures, snow or ice, various colours and tints will heighten the
effect as they do in reality. It the size in diameter be doubled, the
impression of the sight is increased, and the relief is represented with
much greater accuracy. If you construct a very large globe on the scale
of 1 to 100,000, then all the details of elevation and depth will appear
most distinctly, even hills and hillocks 150 feet in height. You see the
very Earth as if you were sailing above it in a balloon. The
representation of such heights, whose appearance our eyes are accustomed
to, gives us an unexpected advantage by furnishing us with a standard of
comparison. To give us an idea of the real height of a building,
photography and painters put men or women standing all around or leaning
against the pillars. Thus spectators of a relief will easily estimate,
by comparison with known heights, the real dimensions of the hills and
mountains which diversify the surface.
There has been in Switzerland lately a very interesting public
controversy. A skilful cartographer and relief maker (M. Charles Perron)
had proposed to the Federal Council to construct, for the Paris
Exhibition, a relief of Switzerland on the scale of 1 to 100,000, which,
he said, would do honour to the country; and, indeed, the samples of the
work which he exhibited at Bern and Geneva excited general admiration.
Evidently the undertaking deserved to be encouraged, and it would have
been taken under the official patronage of the Swiss Republic if a few
influential geodesists had not interfered, asserting that a true and
perfectly detailed representation of nature wanted a larger scale than
the 100,000thb. As in examples of their contention, they referred to the
parting of slopes on nearly horizontal ground; the geographical changes
brought in the configuration of a valley by the advance of a morainic
ridge; the displacement of the courses of rivers caused by landslips and
erosions—all facts of small magnitude in their origin, but of great
geographical importance, and which are to be fully represented on large
relief to be clearly understood. Pamphlets and articles were published
on both sides, and the question was fully elucidated by most competent
scholars.
Now we may resume the discussion. According to the effect which must be
attained, and the elaborate study which is aimed at, scales must be
different in globes, as also they are in all other modes of
representation, maps, charts, and plans.
If our intention is to show the majestic appearance of the Earth, with
its continents and seas, with its mountains, rivers, and plains, if it
is to give a perfect idea of the interaction and interdependence of all
organs in the grand planetary body; then, by all means, let us construct
a large globe, where we may be impressed by the mass itself, by the
harmonious forms of the countries we know, and specially love and study.
But if our aim is to show the details as, thoroughly as possible, and
the means be not sufficient to construct the globe at a convenient
scale, the only way is to model fragments or parts of sphere in
proportion of 1 to 50,000, 25,000, 20,000, 10,000, 5000, as may be
desirable. With the increase of these treasures, geographical societies
will acquire documents enough to represent in reality whole parts of the
Earth in miniature, attaining the utmost perfection, and satisfactory
both to the learned and the artists.
This is, in fact, the thing which will be done in Switzerland. Two
objects are to be attained, and therefore work will be directed in both
ways. I hear M. Perron's great work will be pushed on with great
enthusiasm, and we may hope to see, two years hence, in the Paris
Exhibition, his complete relief of Switzerland on the scale of
100,000—the most complete, and certainly the best of the kind, which
geography will possess; and, on the other side, all those who have
carefully inspected the Polytechnium in Zurich know what splendid
achievements local geodesists have made in the shape of mountain-reliefs
on very large scales, showing and explaining at the same time the
features of the country. Nowhere in the civilized world do we find so
much and so great work accomplished in the way we recommend.
Among the conquests of a proximate future, I think a better division of
labour will be introduced in geographical bodies. Already a very great
improvement has been made in the scales of maps, especially for large
geographical works. Nearly all these are now constructed according to a
scale with very convenient decimal numbers, 100,000, 50,000, 40,000,
20,000, which allow us easy arithmetical comparison, all numbers being a
multiple or a decimal fraction of another. The United States squeezed,
so to say, between two tendencies, to measure still in the ancient way,
by inches or parts of an inch to the mile, or to deal with great decimal
masses, have chosen for their maps the various scales of 250,000,
125,000, and 62,500, which last measure is so very near to the
proportion " one inch to the mile," that it may be considered as
practically the same. In reliefs, even more than in maps, the habit has
become general to take regular scales with full thousands and tens of
thousands; thus comparisons are more easily made between the various
productions. This tendency of relief-makers will, I hope, grow more and
more common, and gradually, by mutual, though informal, aareement, their
works will be made according to a few commodious patterns, and
constitute as many different parts of great globes constructed on the
same scale. If all these disjointed and scattered parts, well reproduced
and regularly exchanged between the authors and the geographical
societies, were collected and put together, the construction of entire
globes on very large scales would be found very much advanced. People
would be astonished to see what large fragments of continents in relief
we already possess, if they saw in a great hall, put in their proper
place, all the plans of the Alps, Pyrenees, and Auvergne, and other
mountainous lands. These relief constructions on large scales are the
necessary complement to the lesser globes, for whose construction we
plead urgently.
This spontaneous organization of labour which pervades the scientific
workers in the common field will prevail more and more. We see already
the various geographical societies uniting every yearmore intimately to
distribute thebusiness among themselves. Small societies have their very
important part for local efficiency, and we may expect from them
searching studies on the special questions relative to their own or
surrounding countries. Larger bodies residing in important seaports or
commercial centres have a greater field of action, and their natural
circle of study embraces especially the parts of the world which belong
to the general market of their cities; lastly, the societies, whose area
of action and reaction is the immense world at large, are invested with
a mission of high and noble import—to centralize every document
belonging to the Earth at large, and to any part of it specially; to
collect in their libraries all the books, all the pamphlets and
documents, that have been written or published anywhere in the world; to
have the entire set of maps, charts, and plans which have been
constructed and drawn by geographers and engineers in the entire world;
and especially to offer to their guests, who are, so to say, the
delegates of all mankind, a model of the Earth, under the shape of a
globe, vast in dimensions, where every man will find himself at home,
and even will learn to know his own country better than before, where he
may also indicate all possible corrections and improvements;-such a
model, in fact, which will afford a standard of scientific perfection
which human intellect and skill are able to attain. This is, I think,
what the legitimate ambition of a geographical society ought to realize,
and will certainly realize, in the proximate future.
Among all the riches which I foresee in our palaces and museums on
geography, there is one, as is implied in the subject of my lecture, to
which I look forward with an intense desire. Now, at a time when every
morning and evening newspaper brings us news from all parts of the
world; when every one of us, even the least fortunate, is fed and
clothed with productions of all continents and seas; when we all have
friends across both oceans in the antipodal countries;-the moment has
come for us to have grand representations of our common home, and not to
satisfy ourselves with petty spheres, round copper balls, similar to
that which Krates of Melos exposed to the curiosity of men in the temple
of Pergamos, twenty-one centuries ago. Now Globes must be temples
themselves, as well by the magnificence or proportions as by the beauty
of workmanship and the scrupulous care of scientific drawing. In sight
of such constructions, people must feel grave and respectful, not only
because those monuments consecrated to science will partake of its
majesty, but also because they will belong to all men, without any
privilege for race or nationality, and will help to strengthen within us
the feeling that we are one and the same family.
