The pups are weaned at the end of forty days, but are still fed with goat's, or camel's milk, thickened with dates, or kouskoussou. In the Sahara, the flocks are so numerous and milk so abundant, that it is not at all surprising that wealthy Arabs, after having weaned their greyhound pups, should set aside so many she-goats for their nourishment. When the pups are three or four months old, their education commences. The boys drive out of their holes the jerboa, or the rat called _boualal_, and set the pups at them. The latter by degrees get excited, dash after them at full speed, bark furiously at their holes, and only give up the pursuit to begin another. At the age of five or six months, they are assigned a prey more difficult to catch—the hare. Men on foot lead the greyhound close to the form where the animal is couched. Then, by a slight exclamation, they set the young dog, who rushes at the hare, and soon acquires the habit of coursing with speed and intelligence. From the hare, they pass to the young of the gazelle. The Arabs approach the spot where these are lying near their mother, and direct the attention of the greyhound to them. As soon as he is thoroughly excited and rears up with impatience, they let him go. After a few lessons of this kind, the greyhound understands perfectly what to do, and begins to press forward resolutely in chace of the old hinds themselves. When a year old the greyhound has very nearly reached its full strength. His scent is developed, and he follows the gazelle by its slot. Nevertheless, he is kept under some restraint, and not until the age of fifteen to eighteen months is he regularly allowed to hunt. From that period, however, he is held in leash, and often with great difficulty; for the Arabs say that when the greyhound scents the game, his muscular power becomes so great that, if he stiffens himself upon his paws, a man can hardly make him lift a leg. As soon as he sights a herd of thirty or forty gazelles, he trembles with joy, and looks up at his master, who cries to him: "Ah son of a Jew! thou canst not say this time that thou didst not see them." The hunter then takes off his goat's-skin bag, and pours a little water on the back and belly of the hound, who, in his impatience, casts a suppliant eye on his master. At last, he is free and bounds forward. Presently, he tries to hide himself, stoops down, and follows a circuitous course until he is within an easy distance, when he springs forward with all his might, and picks out for his victim the finest male in the herd. When the hunter cuts up the gazelle, he throws to the _slougui_ the flesh around the kidneys. If he were to offer him the intestines, he would reject them with disdain. The greyhound that cannot hunt at two years old, will never be able do so. There is a saying to this effect, A greyhound after two years And a man after two fasts [fifteen years];
