_Jumars._—The reputed offspring of the ass and the bull, or cow, is an animal whose existence is still doubted; I have never, in any of my travels, seen such a one; but I was once informed by Sid Mohammed E——m, that such a beast was sometimes seen in Bled-el-jerrêde; he had not, however, seen it himself. Dr. Shaw has described one that he saw in Barbary; notwithstanding which, the Count de Buffon disputes its existence. These observations on the more remarkable _wild_ animals may serve as a clue to future travellers; their names in the language of the country being accurately given, it will not be difficult to procure some of the natives to direct where to find them, by which means their respective species may be ascertained by those who may be desirous of elucidating natural history. I shall now mention the most particular _domestic_ quadrupeds, or such as are subservient to the use of man. _El Heirie_, or _Erragual._—Nature, ever provident, and seeing the difficulty of communication, from the immense tracts of desert country in Sahara, has afforded the Saharawans a means, upon any emergency, of crossing the great African desert in a few days; mounted upon the (Heirie) desert camel (which is in figure similar to the camel of burden, but more elegantly formed), the Arab, with his loins, breast, and ears bound round, to prevent the percussion of air proceeding from a quick motion rapidly traverses, upon the back of this abstemious animal, the scorching desert, the fiery atmosphere of which parches, and impedes respiration so as almost to produce suffocation. The motion of the heirie is violent, and can be endured only by those patient, abstemious, and hardy Arabs who are accustomed to it.[87] The most inferior kind of heirie are called Talatayee, a term expressive of their going the distance of three days journey in one: the next kind is called Sebayee, a term appropriated to that which goes seven days journey in one, and this is the general character; there is also one called Tasayee, or the heirie of nine days; these are extremely rare. The Arabs affirm that the Sebayee does not always produce another Sebayee, but sometimes a Talatayee, and sometimes a Tasayee; and that its class is ascertained by the period which elapses before the young one takes the teat of the mother; thus, if it be three days, it is considered to be a Talatayee, if seven days, a Sebayee, and if nine days, it proves to be a Heirie of nine days journey. If it prove a Tasayee, there are great rejoicings, it being an accession of wealth to the proprietor, as a Tasayee is bartered for two hundred camels; the Sebayee for one hundred, and the Talatayee for thirty, or thereabout.
