The soil that a Camel most hates is a wet and muddy ground, on which it is nearly sure to slip. If the reader will look at a Camel from behind, he will see that the hinder legs are close together until the ankle-joint, when they separate so widely that the feet are set on the ground at a considerable distance from each other. On dry ground this structure increases the stability of the animal by increasing its base; but on wet ground the effect is singularly unpleasant. The soft, padded feet have no hold, and slip sideways at every step, often with such violence as to dislocate a joint and cause the death of the animal. When such ground has to be traversed, the driver generally passes a bandage round the hind legs just below the ankle-joint, so as to prevent them from diverging too far.

It must be remarked, however, that the country in which the animal lives is essentially a dry one, and that moist and muddy ground is so exceptional that the generality of Camels never see it in their lives. Camels do not object to mud an inch or two deep, provided that there is firm ground below; and they have been seen to walk with confident safety over pavements covered with mud and half-frozen snow.

The animals can ford rivers well enough, provided that the bed be stony or gravelly; but they are bad swimmers, their round bodies and long necks being scarcely balanced by their legs, so that they are apt to roll over on their sides, and in such a case they are sure to be drowned. When swimming is a necessity, the head is generally tied to the stern of a boat, or guided by the driver swimming in front, while another often clings to the tail, so as to depress the rump and elevate the head. It is rather curious that the Camels of the Sahara cannot be safely entrusted to the water. They will swim the river readily enough; but they are apt to be seized with illness afterwards, and to die in a few hours.

We now come to some other uses of the Camel.

Its hair is of the greatest importance, as it is used for many purposes. In this country, all that we know practically of the Camel's hair is that it is employed in making brushes for painters; but in its own land the hair plays a really important part. At the proper season it is removed from the animal, usually by being pulled away in tufts, but sometimes by being shorn like the wool of sheep, and it is then spun by the women into strong thread.

From this thread are made sundry fabrics where strength is required and coarseness is not an objection. The "black tents" of the Bedouin Arabs, similar to those in which Abraham lived, are made of Camel's hair, and so are the rugs, carpets, and cordage used by the nomad tribes. Even mantles for rainy or cold weather are made of Camel's hair, and it was in a dress of this coarse and rough material that St. John the Baptist was clad. The best part of the Camel's hair is that which grows in tufts on the back and about the hump, the fibre being much longer than that which covers the body. There is also a little very fine under-wool which is carefully gathered, and, when a sufficient quantity is procured, it is spun and woven into garments. Shawls of this material are even now as valuable as those which are made from the Cachmire goat.

The skin of the Camel is made into a sort of leather. It is simply tanned by being pegged out in the sun and rubbed with salt.

Sandals and leggings are made of this leather, and in some places water-bottles are manufactured from it, the leather being thicker and less porous than that of the goat, and therefore wasting less of the water by evaporation. The bones are utilized, being made into various articles of commerce.

So universally valuable is the Camel that even its dung is important to its owners. Owing to the substances on which the animal feeds, it consists of little but macerated fragments of aromatic shrubs. It is much used as poultices in case of bruises or rheumatic pains, and is even applied with some success to simple fractures. It is largely employed for fuel, and the desert couriers use nothing else, their Camels being furnished with a net, so that none of this useful substance shall be lost. For this purpose it is carefully collected, mixed with bits of straw, and made into little rolls, which are dried in the sun, and can then be laid by for any time until they are needed.

Mixed with clay and straw, it is most valuable as a kind of mortar or cement with which the walls of huts are rendered weather-proof, and the same material is used in the better-class houses to make a sort of terrace on the flat roof. This must be waterproof in order to withstand the wet of the rainy season, and no material answers the purpose so well as that which has been mentioned. So strangely hard and firm is this composition, that stoves are made of it. These stoves are made like jars, and have the faculty of resisting the power of the inclosed fire. Even after it is burned it has its uses, the ashes being employed in the manufacture of sal-ammoniac.
