The vegetation in the neighbourhood of Bóse-bángo is extremely rich; but as we advanced gradually the trees ceased, with the exception of the kálgo, the bush so often mentioned by me in Háusa, and which here begins to be very common. I was greatly disappointed in my expectation of making a good day’s march, for, after proceeding a little more than three miles, I saw my tent, which had gone in advance, pitched in the neighbourhood of an encampment of Arabs belonging to the tribe of the Ergágeda. Here we stayed the remainder of the day, enjoying the hospitality of these people, who had to pay dearly for the honour of such a visit; for the pupils of my friend, who had capital appetites, required a great deal of substantial nourishment to satisfy their cravings; and besides a dozen dishes of rice, and a great quantity of milk, two oxen had to be slaughtered by our hosts. These Arabs, who formed here an encampment of about twenty-five spacious tents, made of sheepskins or fárrwel, have no camels, and possess only a few cows, their principal herds being sheep and goats, besides a large number of asses. They have been settled in this district, near the river, since the time when Sídi Mukhtár, the elder brother of El Bakáy, established himself in Timbúktu, that is to say, in the year 1832. Although I should have liked much better to have made at once a fair start on our journey, I was glad that we had at least set out at all, and, lying down in the shade of a small kálgo tree, I indulged in the hope that in a period of from forty to fifty days I might reach Sókoto; but I had no idea of the unfavourable circumstances which were gathering to frustrate my hopes. The whole of this district is richly clothed with siwák, or ʿirák (_Capparis sodata_), and is greatly infested with lions, for which reason we were obliged to surround our camping-ground with a thick fence, or zeríba; and the encampment of the Sheikh, for whom an immense leathern tent had been pitched, with his companions, horses, and camels, together with the large fires, presented a very imposing appearance. I was told that the lion hereabouts has no mane, or at least a very small one, like the lion of Ásben. [Sidenote: Thursday, April 20th.]
