The _terbigue_ is, in fact, a robbery, but it is at the same time almost a warlike operation—it is, at least, a _razzia_. The strength of the party that executes the enterprise, the importance of the wrong inflicted upon an entire division of a tribe, the high qualities of the perpetrators of the robbery, who, after all, are real warriors,—all these circumstances taken together, if they do not suffice as a justification in the eyes of scrupulous Europeans, are esteemed in the desert as extremely plausible motives. Since a few brave and reckless fellows have imperilled their lives to injure a hostile tribe, there cannot be otherwise than joy and triumph in that to which they belong. In the _khriana_, however, we descend a step lower, and arrive at a mere marauding expedition, executed by professional thieves. It is no longer war, even in miniature—it is nothing more than theft. It is no longer a subject of rejoicing for a whole tribe, though still a matter for praise and congratulation among friends; always provided the robbery has not been committed on their own or on a friendly tribe—which would be a disgrace—but absolutely on an enemy. They say, "Such a one is a brave man—he robs the enemy." As may readily be imagined, all thefts are not managed in the same manner, but are adapted to the nature of the capture that is proposed to be made. HORSE-STEALING. This species of theft is practised towards the end of the Mussulman month. When the moon is scarcely visible, five or six men, having a proper understanding between themselves, take a supply of provisions with them in their wallets, and go forth in search of adventures. Before starting, they give alms to the poor, and intreat them to intercede with Allah for the success of their enterprise. They then swear by some well-known marabout, generally Sidi Abd-el-Kader, that, if they succeed, they will do him homage by putting aside a portion for the unfortunate. "O Sidi Abd-el-Kader," they exclaim, "if we return with joy, loaded with spoils and free from accident, we will give thee thy lance's share, if it please Allah!"
