Camel in Wikipedia
Camel, a prominent domestic animal of the East without the existence of which life in the Arabian deserts would be impossible. It was perhaps the first beast of burden applied to the service of man. It is mentioned as such in the Biblical records as early as the time of Abraham. It constituted a great element in the riches of the early patriarchs. There are two species of camel: the one-humped camel (camelus dromedarius), and the two-humped camel (camelus bactrianus). The camel is used for riding as well as for carrying loads; its furniture is a large frame placed on the humps, to which cradles or packs are attached. In this manner was all the merchandise of Assyria and Egypt transported. But the camel is appreciated for other reasons: it may be hitched to a wagon or to a plough, and in fact is not unfrequently yoked together with the ass or the ox; the female supplies abundantly her master with a good milk; camel's hair is woven into a rough cloth wherewith tents and cloaks are made; finally its flesh, albeit coarse and dry, may be eaten. With the Jews, however, the camel was reckoned among the unclean animals.
