The Arab to whom I am indebted for these particulars is an Oulad-Sidi-Shikh, named Abd-el-Kader-Mohammed-ben-Kaddour, a professional hunter. According to him, the country for ostriches is comprised in a triangle contained by lines drawn from Insalah to Figuig, from South to North—from Figuig to Sidi-Okba, from West to East—and from Sidi-Okba to Ouargla, from North to South. GAZELLE HUNTING. The chace of the gazelle is not, like that of the ostrich, at the same time a lucrative and a toilsome enterprise—it is merely an exercise, a pastime, a party of pleasure. The gazelle is barely worth a franc or a franc and a half, and it is not for such a valueless prey that an Arab will prepare, train, fatigue, and even risk the loss of a horse,—as frequently happens in ostrich hunting. Besides, in this species of sport, the chief credit belongs neither to the man nor to the horse,—for whom it is, properly speaking, nothing more than a promenade—but to the greyhound, that other companion of the noble of the desert, of whom I shall have occasion to speak hereafter. If the gazelle be of little value, it is because it is by no means rare. Everywhere, but above all in Sersou, is found the _sine_, or diminutive gazelle; in the Tell and in mountainous districts, the _ademi_, the largest kind; and in the Sahara, the _rime_, or intermediate species, distinguished by the whiteness of its belly and thighs, and the length of its horns. All these varieties alike travel in herds of four, five, ten, twenty, thirty, a hundred; and not unfrequently as many as two or three hundred are found herding together. At a distance they may be taken for the flocks of an emigrating tribe. A herd of gazelles is called a _djeliba_. Gazelle hunting is not a sport exclusively reserved for horsemen. In the incessant and daily wanderings of the Sahara tribes, as soon as the camp is fixed near a fountain or river, the hunters set off in great numbers, taking care to go up the wind. The gazelles possessing a very fine sense of smell, the scent of the men wafted on the wind would soon put them to flight. The hunter advances under shelter of bush after bush, and from time to time imitates the cry of the gazelle. The latter stops, looks about on all sides, and seeks the companion it supposes to have gone astray. The hunter approaches close to it, and may even be seen without scaring it away. At a proper distance he pulls the trigger, and rarely misses his aim, "unless a spell cast upon his rifle causes it to hang fire, and prevents it from going off during the whole day." At the sound of the report the entire herd dashes off at top speed, but at the end of a league or a league and a half, their fright has passed off with the recollection of the cause of their alarm, and they again halt and go on browsing as before.
