The few wild animals which inhabit these melancholy regions are the antelope and the ostrich; their swiftness of foot enabling them to reach the distant watering-places. On the skirts of the desert, where water is more plentiful, are found lions, panthers, elephants, and wild boars. Of domestic animals, the only one that can endure the fatigue of crossing the desert is the camel. By the particular conformation of the stomach he is enabled to carry a supply of water sufficient for ten or twelve days; his broad and yielding foot is well adapted for a sandy country; and, by a singular motion of his upper lip, he picks the smallest leaves from the thorny shrubs of the desert as he passes along. The camel is therefore the only beast of burden employed by the trading caravans which traverse the desert in different directions, from Barbary to Nigritia. As this useful and docile creature has been sufficiently described by systematical writers it is unnecessary for me to enlarge upon his properties. I shall only add that his flesh, though to my own taste dry and unsavoury, is preferred by the Moors to any other; and that the milk of the female is in universal esteem, and is indeed sweet, pleasant, and nutritive. I have observed that the Moors, in their complexion, resemble the mulattoes of the West Indies; but they have something unpleasant in their aspect which the mulattoes have not. I fancied that I discovered in the features of most of them a disposition towards cruelty and low cunning; and I could never contemplate their physiognomy without feeling sensible uneasiness. From the staring wildness of their eyes a stranger would immediately set them down as a nation of lunatics. The treachery and malevolence of their character are manifest in their plundering excursions against the negro villages. Oftentimes without the smallest provocation, and sometimes under the fairest professions of friendship, they will suddenly seize upon the negroes’ cattle, and even on the inhabitants themselves. The negroes very seldom retaliate. Like the roving Arabs, the Moors frequently remove from one place to another, according to the season of the year or the convenience of pasturage. In the month of February, when the heat of the sun scorches up every sort of vegetation in the desert, they strike their tents and approach the negro country to the south, where they reside until the rains commence, in the month of July. At this time, having purchased corn and other necessaries from the negroes, in exchange for salt, they again depart to the northward, and continue in the desert until the rains are over, and that part of the country becomes burnt up and barren.
