A second favour more important than the first occurred by chance. Another Sidy-Mahammet, who was sheriff of the tribe of the Trarzas, had occasion to pass through the place where M. de Brisson was enslaved, and they recognised each other. The sheriff spoke so highly of him to the brother-in-law of his master, Sidy-Sellem, that the latter, who was naturally humane and compassionate, made a second attempt to purchase him, and the bargain was at length concluded. The price of his transfer was five camels. Sidy-Sellem was the first who informed M. de Brisson of the change, which was soon confirmed by his former master, and they separated on the best terms. M. de Brisson, on returning with his new owner, met with a companion of his misfortune, who had been baker to the wrecked ship, and they travelled together under the protection of Sidy-Sellem. Their master had given them a camel to ride on without a saddle, and they proceeded in this manner for some days; but the motion of the animal was so fatiguing, that they were obliged to quit it and travel the rest of the way on foot. This journey was difficult, but much less so than the former, as their master took them through villages where water was plentiful, and the people were more feeling. M. de Brisson, however, had a shocking rencontre with some Moors of the tribe of Telkannes. They fired two muskets at him, but which luckily missed him. Two Moors then seized him, and were about to carry him off, when Sidy-Sellem, who was some distance behind, came forward on the report of the guns, and loudly complained of the outrage; but the Moors told him that they had taken the slave for a thief who had run away, Sidy-Sellem pretended to believe them, and the travellers continued their journey. The Moors of this tribe are the worst off of any in the desert. They live amongst hills which are formed entirely of sand raised by the wind; and it is so difficult to penetrate into their retreats, that it is a common saying, that they endeavour to conceal themselves from the rays of the sun: the plains in the neighbourhood contain great numbers of enormous serpents, which do not permit the cattle to approach them.
