It will be seen from these instances that the charge of stupidity is not an undeserved one. Still the animal has enough intellect to receive all the education which it needs for the service of man, and which it receives at a very early age. The ordinary Camel of burden is merely taught to follow its conductor, to obey the various words and gestures of command, and to endure a load. The Deloul, however, is more carefully trained. It is allowed to follow its mother for a whole year in perfect liberty. Towards the expiration of that time the young animal is gradually stinted in its supply of milk, and forced to browse for its nourishment. On the anniversary of its birth, the young Deloul is turned with its head towards Canopus, and its ears solemnly boxed, its master saying at the same time, "Henceforth drinkest thou no drop of milk." For this reason the newly-weaned Camel is called Lathim, or the "ear-boxed." It is then prevented from sucking by a simple though cruel experiment. A wooden peg is sharpened at both ends, and one end thrust into the young animal's nose. When it tries to suck, it pricks its mother with the projecting end, and at the same time forces the other end more deeply into the wound, so that the mother drives away her offspring, and the young soon ceases to make the attempt.
The food of the Camel is very simple, being, in fact, anything that it can get. As it proceeds on its journey, it manages to browse as it goes along, bending its long neck to the ground, and cropping the scanty herbage without a pause. Camels have been known to travel for twenty successive days, passing over some eight hundred miles of ground, without receiving any food except that which they gathered for themselves by the way. The favourite food of the Camel is a shrub called the ghada, growing to six feet or so in height, and forming a feathery tuft of innumerable little green twigs, very slender and flexible. It is so fond of this shrub that a Camel can scarcely ever pass a bush without turning aside to crop it; and even though it be beaten severely for its misconduct, it will repeat the process at the next shrub that comes in sight.
It also feeds abundantly on the thorn-bushes which grow so plentifully in that part of the world; and though the thorns are an inch or two in length, very strong, and as sharp as needles, the hard, horny palate of the animal enables it to devour them with perfect ease.
There are several species of these thorn-shrubs, which are scattered profusely over the ground, and are, in fact, the commonest growth of the place. After they die, being under the fierce sun of that climate, they dry up so completely, that if a light be set to them they blaze up in a moment, with a sharp cracking sound and a roar of flame, and in a moment or two are nothing but a heap of light ashes. No wonder was it that when Moses saw the thorn-bush burning without being consumed he was struck with awe at the miracle. These withered bushes are the common fuel of the desert, giving out a fierce but brief heat, and then suddenly sinking into ashes. "For as the crackling of thorns under a pot, so is the laughter of the fool" (Eccl. vii. 6).
The dried and withered twigs of these bushes are also eaten by the Camel, which seems to have a power of extracting nutriment from every sort of vegetable substance. It has been fed on charcoal, and, as has been happily remarked, could thrive on the shavings of a carpenter's workshop.
Still, when food is plentiful, it is fed as regularly as can be managed, and generally after a rather peculiar manner. "Our guide," writes Mr. Hamilton, in the work which has already been mentioned, "is an elderly man, the least uncouth of our camel-drivers. He has three camels in the caravan, and it was amusing to see his preparations for their evening's entertainment. The table-cloth, a circular piece of leather, was duly spread on the ground; on this he poured the quantity of dourrah destined for their meal, and calling his camels, they came and took each its place at the feast. It is quaint to see how each in his turn eats, so gravely and so quietly, stretching his long neck into the middle of the heap, then raising his head to masticate each mouthful; all so slowly and with such gusto, that we could swear it was a party of epicures sitting in judgment on one of Vachette's chefs d'œuvre ."
The foregoing passages will show the reader how wonderfully adapted is the constitution of the Camel for the country in which it lives, and how indispensable it is to the inhabitants. It has been called "the ship of the desert," for without the Camel the desert would be as impassable as the sea without ships. No water being found for several days' journey together, the animal is able to carry within itself a supply of water which will last it for several days, and, as no green thing grows far from the presence of water, the Camel is able to feed upon the brief-lived thorn-shrubs which have sprung up and died, and which, from their hard and sharp prickles, are safe from every animal except the hard-mouthed Camel.
But these advantages would be useless without another—i.e. the foot. The mixed stones and sand of the desert would ruin the feet of almost any animal, and it is necessary that the Camel should be furnished with a foot that cannot be split by heat like the hoof of a horse, that is broad enough to prevent the creature from sinking into the sand, and is tough enough to withstand the action of the rough and burning soil.
Such a foot does the Camel possess. It consists of two long toes resting upon a hard elastic cushion with a tough and horny sole. This cushion is so soft that the tread of the huge animal is as noiseless as that of a cat, and, owing to the division of the toes, it spreads as the weight comes upon it, and thus gives a firm footing on loose ground. The foot of the moose-deer has a similar property, in order to enable the animal to walk upon the snow.
In consequence of this structure, the Camel sinks less deeply into the ground than any other animal; but yet it does sink in it, and dislikes a deep and loose sand, groaning at every step, and being wearied by the exertion of dragging its hard foot out of the holes into which they sink. It is popularly thought that hills are impracticable to the Camel; but it is able to climb even rocky ground from which a horse would recoil. Mr. Marsh, an American traveller, was much surprised by seeing a caravan of fifty camels pass over a long ascent in Arabia Petræa. The rock was as smooth as polished marble, and the angle was on an average fifteen degrees; but the whole caravan passed over it without an accident.
