Overweg and I, accompanied by Khálef-Allah and a guide, made an excursion down the river, in order, if possible, to reach its mouth; but the experiment proved that there is no path on the southern shore, the track following the northern bank: for on that side, not far from the mouth, lies a considerable Kánembú place called Bóso, though, in the present weak state of the Bórnu kingdom, much exposed to the incursions of the Tawárek. Having penetrated as far as a village, or rather a walled town, named Fátse, the walls of which are in a decayed state, and the population reduced to a dozen families, we were obliged to give up our intended survey of the river. As for myself, I was scarcely able to make any long excursion; for, on attempting to mount my horse again, I fainted, and fell senseless to the ground, to the great consternation of my companions, who felt convinced my end was approaching. We therefore returned to our encampment. In the evening I had a severe attack of fever.[6] [Sidenote: Saturday, Sept. 20th.] It had been determined the day before that we should cross the river to- day, and the governor’s permission had been obtained; but as the vizier’s messenger had not yet arrived, we decided upon waiting another day. Feeling a little better, I made a rough sketch of the town, with the dúm-palms around it, and prepared myself, as well as I was able, for the fatiguing march before me. We had a good specimen to-day of the set of robbers and freebooters we had associated with in order to carry out the objects of the mission. The small Tébu caravan, which I mentioned above as having arrived from Kánem, and which had brought the news that the people of Wadáy had made an alliance with all the tribes hostile to the Welád Slimán, in order to destroy the latter, had not been allowed to cross the river until to-day. They were harmless people, carrying very little luggage (chiefly dates) upon a small number of oxen; but as soon as they had crossed, our companions held a council, and, the opinion of the most violent having gained the upper hand, they fell upon the poor Tébu, or Kréda, as they call them, and took away all their dates by force. The skins were then divided; and the greater part of them had already been consumed or carried away, when an old Arab arrived, and, upbraiding his companions with their mean conduct, persuaded them to collect what remained, or that could be found, and restore it to the owners. In the evening the vizier’s messenger arrived, and the crossing of the river was definitively fixed for the next day. [Sidenote: Monday, Sept. 22nd.]
