The fat of the ostrich is used in the preparation of the favorite dish _kouskousson_, and is often eaten with bread. It is also used medicinally. In cases of fever, for instance, the Arabs make a paste with it and bread-crumb, which is given to the patient, who must not drink any thing during the whole day. In rheumatism, and in renal diseases, the painful parts are rubbed with the grease until it disappears. The patient then lies down in the scorching sand, his head being carefully covered, and a profuse perspiration ensuing, the cure is often complete. In bilious attacks, the fat is melted, salted, and taken in draughts, with powerful effect, the patient even becoming extremely thin. The Arab doctors say, “the patient parts with every thing in his body that is bad, gains a frame of iron, and acquires excellent eyesight.” Ostrich fat is sold in the markets, and in the tents of the great a store is kept to give away to the poor—in value, one pot of this fat is equivalent to three pots of butter. The feathers of the ostrich are sold at the _ksours_, at Tougartet: at the time of the purchase of grain, the ostrich-skins are bought, that of a male selling for four or five _douros_, that of a female from eight to fourteen shillings. Formerly, the only use made in the Sahara of the plumes was to decorate the tops of tents. To the Arab, the chase of the ostrich has a double attraction—pleasure and profit: the price obtained for the skins well compensates for the expenses. Not only do the rich enjoy the pursuit, but the poor, who know how to set about it, are permitted to participate in it also. The usual plan is, for a poor Arab to arrange with one who is opulent for the loan of his camel, horse harness, and two-thirds of all the necessary provisions. The borrower furnishes himself the remaining third, and the produce of the chase is divided in the same proportions. The use of ostrich-fat in medicine dates back to a very remote period: and Pliny relates that, on a certain occasion, when Cato—surnamed Uticensis—was accused of selling poison, because “he held cantharides at three-score sesterces a pound, at the same time ostrich-grease was sold for eighty sesterces the pound; and, in truth, it is much better for any use it shall be put unto than goose-grease.” In the quaint account of “The World encompassed by Sir Francis Drake,” there is a curious description of the mode of hunting ostriches, as practiced in those days at the Cape. The history is written by “Mr. Francis Fletcher, preacher in this employment,” and he thus begins:
