The shoes are joined at the heel. As the horse can only suffer in the part that is quick, and not in the part that is hard, it is, of course, the frog that should be shielded from accident. The shoes should therefore follow the curvature of the frog. They give to the nail-heads the form of a grasshopper's head, the only form, as they allege, that allows the nails to be worn down to the last without breaking. They approve of our method of driving the nails into punched holes and clinching them outside, which prevents a horse from cutting himself; but their scarcity of iron obliges them to content themselves, for their part, with hammering the nails down upon the hoof, so as to render them serviceable a second time by making a new head. If a horse overreaches himself they cut away his heels and place light shoes on his forefeet, but heavier ones on his hindfeet. They are careful not to leave one foot shod and the other bare. If during an excursion a horse happens to cast one of his fore-shoes, and his rider has not a fresh supply with him, he takes off both the hind shoes and puts one of them on the forefoot; and if the animal is shod only on his forefeet, the rider will take the shoe off the other foot, rather than leave him in such a condition. Should a horse, after a long journey such as the horsemen of the desert not unfrequently make, require to be shod, it is no uncommon thing to place a morsel of felt between the shoe and the foot. The necessity, caused partly by the nature of the ground and partly by the length of their excursions, of shoeing the horses of the Sahara, has shown the expediency of accustoming the colt to let himself be shod without resistance. They therefore give him kouskoussou, cakes, dates, etc., while he allows them to lift his foot and knock upon it. They then caress his neck and cheeks, and speak to him in a low tone; and thus after a while he lifts his feet whenever they are touched. The little difficulty experienced at a later period, thanks to this early training, has probably given rise to the Arab hyperbole: "So wonderful is the instinct of the thoroughbred horse that if he casts a shoe he draws attention to it himself by showing his foot." This exaggeration at least proves how easy these horses are to be shod, and further explains how every horseman in the desert ought to have the knowledge and the means of shoeing his own horse, while on a journey. It is a point of the highest importance. It is not enough to be very skilful in horsemanship, or to train a horse in the most perfect manner, to acquire the reputation of a thorough horseman—in addition to all this, he must likewise be able to put on a shoe if necessary. Thus on setting out for a distant expedition every horseman carries with him in his _djebira_ shoes, nails, a hammer, pincers, some strips of leather to repair his harness, and a needle. Should his horse cast a shoe, he alights, unfastens his camel-rope, passes one end round the _kerbouss_ of the
