PART VI. CLOUDLAND.

[Sidenote: Cloudland]

We have seen the close resemblance of warm winds and seas between the

North Atlantic and the North Pacific; but it was only in the North

Atlantic region that the great Ice Age, in long pulsations, widened

and shrank its Icefields. Ten thousand years ago (Wright) in the

Niagara District, and seven thousand years ago (de Geer) in Finland,

the edges of the Icefield were withdrawn for the last time, and the

climate began to get warm and comfortable.

In America and in Europe, as the ice retreated, a belt of tundra

crept closely in its wake, and in the rear of that a belt of green

turfed grasses.

In Eastern Canada, and North-western Europe these green turfed

pastures are varied with woodlands of such trees as cast their leaves

in winter. Amid these changes the horse had vanished from North

America, but survived in Asia, and slowly extended his range as the

ice retreated from Europe. In Europe {34} as in America, man also

widened his hunting grounds in the wake of the melting Icefield.

In the big region of the south-west wind the lands which surround the

North Sea and the Baltic are different from all others, being under a

low sun, cloudy, with only one day's sunshine out of seven. And

Cloudland breeds a special type of man with blue eyes, a ruddy skin,

and hair of chestnut, bay, brown, or dun, colours like those of

horses.

Under the grey skies of Cloudland, man lacks the protective colour

which in all other regions of the world defends the body from actinic

light. I think we shall find this true of the horse also.

The original striped colouring of the Bays and Duns never developed

in Western Europe with its climate of cloudy skies and verdant

pastures.

[Sidenote: The white horse]

THE WHITE HORSE. Now let us study the conditions following the Ice

Age in Southern Russia. Here the Dun horse has a white coat for

sunny snowy winters. Rumour says that foals are not born white, and

it must be remembered that snowy winters are recent even as grassy

plains.

This whiteness is not, like the summer colouring, a paint issued by

the body to tint {35} the hair, but a mere absence of any colouring

matter. It is as though the animal saved his stores to paint his

inside to a warm red during the cold season instead of wasting it in

mere vanity upon his outer clothing. At the same time nothing could

be more reasonable than a white coat for concealment against a snowy

background. Hares, Eskimo, and lots of other tribes are most

particular in this matter, and among the best people of all snowy

regions a white suit is the correct mode for winter. It may be that

some tribes of ponies neglected to change in the spring, and so

became conspicuous in summer, a fatal error where there are wolves

about. These were not likely to prosper and raise children except

under man's protection, so one suspects that white coats for summer

wear date only from the human period. Men had a feeling, too, that

the white horse was so beautiful that he must be sacred, a special

gift of the gods. Without any special merit, being indeed of lower

stamina and endurance than any other horses, the white stock were

favoured by breeders. Left to themselves, they would die out rapidly

in any sunny climate. One notes, however, that the Persian wild ass

has a silvery white coat, the hue of his native desert. There are

many animals whose {36} dark hair is white at the tips, so that they

are really brunettes who masquerade as blondes.

[Sidenote: Bearded horses]

BEARDED HORSES. The ancient horse-eating artist-savages of France

have left us portraits of ponies strongly bearded under the lower

jaw. In the earliest portrait we have of the Celtic pony (Ewart),

Odin's eight-legged Sleipnir shows the coarse bearded cut of jaw.

The Celtic pony types are bearded to the northward, clean-shaven

towards the southward parts of their wide range. The Prejevalski,

who is the Tarpan of Asia, is slightly bearded. So is the Kiang or

wild ass of Asia. One finds the beard bristles in all the northern

breeds of horses, not in the desert stocks to the south. Why then

should northern horses want to grow a beard?

A horse has so small a stomach that his day's work to get sufficient

grass is seven hours. Up to about fifty degrees of north latitude,

he gets seven hours of daylight even in mid-winter. Northward of

that he needs beard bristles to aid him in feeling and selecting

grass in the darkness. Southward of that, if he is hunted by wolves

or tigers, he needs a few beard bristles for night grazing except in

cloudless regions where there is always starlight. So, {37} roughly,

the range of bearded horses is that of long dark nights.

[Sidenote: Size]

THE REGISTER OF SIZE. The size of horses varies with their

nourishment.

On the scattered but rich bunch grasses of the desert, where there is

much travel for a little food, the pasture registers the stature of

the Bay as about fourteen hands two inches.

The scattered but rich bunch grass of the American steppe makes

horses prosperous in summer but famished in the winter, so that the

pasture registers a smaller horse than that of the desert--up to

thirteen hands. Under the same conditions we may take the register

of the Dun in Asia as up to thirteen hands.

The poor grass of the British moors registers a pony of ten to eleven

hands.

Strong feeding of grain and hay registers stabled horses up to

nineteen hands.

The great abundance of green turfed grass the year round in

North-western Europe should, under its best conditions, register as

large a horse as either steppe or desert.

[Sidenote: The three pastures]

THE THREE PASTURES. The Bay pasture and the Dun pasture are each of

continental size, whereas the green pasture is only a small province.

In the same way, the rock formations of the Bay and the Dun pastures

are each {38} continuous for several thousands of miles. In sharp

contrast is that little ragged edge of a great continent known as

North-western Europe, a district which has many times been flooded by

the sea, each bath making new beds of rock.

The lowlands of Great Britain, for example, have been frequently

submerged, and the island shows samples of almost every rock

formation known upon the earth. This European pasture then is not

only small, but also varied in its rock formations, its soils, and

its landscape. One may get a standard horse of registered size in

the Bay range or the Dun range, but would expect to find on the green

range of Europe not only many colours, but also many types derived

from the primitive stock, strains of all sorts and sizes. A glance

at three formations will show how much the build and size of a horse

is varied by the rocks.

GRANITE. In North-western Europe the granitic or speckled formations

form upstanding moorlands. The poor but abundant grass maintains

ponies both light and heavy of build, derived from several kinds of

ancestors. They are so secured from attack by beasts of prey that

they do not need to run far and fast on ground where running would be

dangerous. {39} These are grouped under the general name of Celtic

pony.

[Sidenote: Limestone and clay]

LIMESTONE. Allowing for some districts, like the central plain of

Ireland, where the Ice-sheet has left the country very badly drained,

a limestone formation usually makes dry soil. The vegetable mould

may hold a little water and make mud, as on the chalk downs, but the

rock is so porous that most of the rain soaks down, and the waters

run mainly underground. Moreover, the vegetable mould gives chemical

qualities to this water, which is enabled to dissolve the rocks and

form caverns on the underground water courses. At the same time the

water becomes 'hard' with lime in solution, so that the springs will

petrify moss and twigs.

The dryness of the ground tends to make horses sound of bone. The

carbonate of lime in the water supplies them with the material for

bone. As the result the bones are very light in proportion to their

strength. So this pasture registers a well-built and very light

horse. If such an animal is of Bay blood, he is larger and swifter

than the Arab, lacking only in soundness and in travel endurance.

CLAY. As clay holds water, its soils provide abundance to the grass

roots, and so produce {40} thick turf with a great weight of green

forage to the acre. Such heavy feeding without any exercise in

search of water, would, after the killing out of the wolves, tend to

produce a large, heavy, slow-going gentle horse with steady nerves

such as our draught stock, lacking in that soundness of feet and legs

which is limited to the breeds of arid regions.

[Sidenote: Horses of Cloudland]

So far, the argument presents for the green pastures of cloudland

horses of several colours; and, for the varied rock formations in the

North Sea and Baltic basins, horses of many types.

[Sidenote: Forest varieties]

Professor Ewart traces among the ancient wild horses of the forest

species three very distinct types:

1. At the time when the glacial drift of the Rhine and Weser valleys

had a climate like that of the Outer Hebrides of to-day, the

conditions of cold and damp matured the Diluvial horse (Equus

Caballus occidentalis). This animal stood fifteen hands, had a

longer face than the general forest type, was coarsely built, had

heavy fetlocks, a short upright pastern, a broad round foot. This is

the cart horse breed.

2. The Grimaldi Grottoes in the Riviera preserve remains of a

forest-upland horse, {41} large, coarse, heavy in build, with a

short, broad face, and a flat profile.

3. The Solutré Caverns of France preserve paintings made by ancient

savages of a small stout, chunky, bearded horse, rather like a long,

low Iceland pony, with a short broad face, elk-like nose, and low-set

tail, rough-haired towards the root. He stood from twelve to

thirteen hands in height.

From these three forest varieties our draught horses are mainly

descended; but there were also in Ancient Europe two other species

besides that of the woodlands.

_A_. Siwalik type. A fifteen-hand horse, lightly built like the

modern thoroughbred. The forehead recedes at an angle from the line

of the face, and there is a prominence between the eyes. The limbs

are long, withers high, and tail set on high.

_B_. Prejevalski Tarpan steppe type, the Dun of Northern Asia. The

face is long, narrow and straight. The nasal chambers are large,

causing a Roman nose. The limbs are clean, with close hocks and

narrow feet. Height twelve to thirteen hands.

We must think then of such types as the Forest and Siwalik adapting

themselves to the soils of North-western Europe.
