We are on our way to meet the Kailouee Tuaricks, with whom we have arranged in Ghât to conduct us by Aheer to Zinder--a service for which we have already paid a hundred dollars of the money of Ghât. They are a company of merchants returning to their own country, and although they will probably protect us to a certain extent, can scarcely inspire so much confidence as Waled Shafou would have done. We travelled four hours on the 26th. Dr. Barth was again lost this evening, having pushed on in his usual eager way for about half an hour. We were filled with alarm. There were two roads dividing at a certain place, one direct and the other turning off at an angle. Naturally, the Doctor followed the straight road, which proved to be the wrong one. However, knowing he had gone on before, my fears were awakened when we reached the fork; and I immediately fired several guns, and ordered a search to be commenced. The guns not only served as guides to Dr. Barth, but introduced us to the Kailouees, who were close at hand, and came running to meet us. Their appearance, for I scarcely know what reason, sent a thrill of joy through our frames; and the weariness and discouragement we had brought with us from Ghât disappeared. We entertained great hopes of these new companions. The first impression they produced was good; for they greeted us most cheerfully, and began helping to unload the camels. They have several female slaves with them, and muster in all some twenty persons and about thirty camels; so that, altogether, we shall form a very respectable caravan.
