It is almost invariably harnessed to carts, and always in pairs. The mode of yoking the animals is as simple as can well be conceived. A pole runs between them from the front of the vehicle, and the Camels are attached to it by means of a pole which passes over their necks. Oxen were harnessed in a similar manner. It was probably one of these cars or chariots that was mentioned by Isaiah in his prophecy respecting Assyria:--"And he saw a chariot with a couple of horsemen, a chariot of asses, and a chariot of camels" (Isa. xxi. 7). The cars themselves are as simple as the mode of harnessing them, being almost exactly like the ox carts which have already been described. The weight which can be drawn by a pair of these Camels is really considerable. On a tolerably made road a good pair of Camels are expected to draw from twenty-six to twenty-eight hundred weight, and to continue their labours for twenty or thirty successive days, traversing each day an average of thirty miles. It is much slower than the Arabian Camel, seldom going at more than two and a half miles per hour. If, however, the vehicle to which a pair of Bactrians are harnessed were well made, the wheels truly circular, and the axles kept greased so as to diminish the friction, there is no doubt that the animals could draw a still greater load to longer distances, and with less trouble to themselves. As it is, the wheels are wretchedly fitted, and their ungreased axles keep up a continual creaking that is most painful to an unaccustomed ear, and totally unheeded by the drivers. The hair of the Bactrian Camel is long, coarse, and strong; and, like that of the Arabian animal, is made into rough cloth. It is plucked off by hand in the summer time, when it naturally becomes loose in readiness for its annual renewal, and the weight of the entire crop of hair ought to be about ten pounds. The skin is not much valued, and is seldom used for any purpose except for making ropes, straps, and thongs, and is not thought worth the trouble of tanning. The milk, like that of the Arabian animal, is much used for food, but the quantity is very trifling, barely two quarts per diem being procured from each Camel. There is but little that is generally interesting in the Rabbinical writers on the Camel. They have one proverbial saying upon the shortness of its ears. When any one makes a request that is likely to be refused, they quote the instance of the Camel, who, it seems, was dissatisfied with its appearance, and asked for horns to match its long ears. The result of the request was, that it was deprived of its ears, and got no horns. THE HORSE.
