Towards evening the locality was enlivened for a short time by a small slave-caravan, led by Mohammed Trumba or ʿAkerút, an active, energetic man, whom I met several times in the course of my travels, and incurred some obligation towards him, as it was he who, on my setting out from Zinder to Timbúktu in the beginning of 1853, brought me a supply of one thousand dollars, without which I could scarcely have succeeded in my undertaking. He had come in only sixty-five days from Zinder, and thirty-three from Asben, having been obliged to pursue his journey as fast as possible, because, owing to the expedition of the Kél-owí against the Welád Slimán, provisions were very scarce in Asben. He estimated the number of fighting men who had gone on that expedition at seven thousand, and stated that the Tawárek were acting in concert with the Dáza, a tribe of Tébu, whose real name is Búlgudá. He stated that E’ Núr (or Annur, as the name is pronounced), the chief of the Kél-owí, was at present in Tasáwa (that is to say, the town of that name on the borders of Negroland), but would soon return to Asben. He confirmed the report of plenty of rain having fallen in the desert, in consequence of which the wells were full; but he begged me to beware of the cold during the nights, which he represented as very intense. He had twenty-three female slaves with him and only five camels, and hastened on to Tasáwa, in order to obtain dates for his famished people. [Sidenote: Wednesday, June 26th.] Owing to the camels having strayed, it was very late when we left our encampment, and entered a sort of flat valley, from which we ascended to a higher level. From this we obtained a distant glance, towards the W.S.W., of the ruins of a fortress called Kasr Sháraba, the history of which, as it is connected with the struggles of yore between the Tébu and the inhabitants of Fezzán, would be full of interest, if it could be made out distinctly. Towards noon the country wore a more genial aspect, being adorned with several groups of palm-trees. We had to go round a rather steep hill, about 350 feet high, from the summit of which I obtained an interesting view over the desert. The whole country presented a very irregular structure, and scarcely allowed the continuous line of the Wadi Berjúsh to be traced by the eye, hills of considerable height and black pebbly tracts succeeding each other. Over such a desert we continued our march until, late in the afternoon, we reached a spot where the sight of a true wadi, full of herbage and bordered by a strip of talha-trees, gladdened our hearts, and we encamped. It was a pleasant open ground; and the night being cool and refreshing, we felt very much invigorated when we rose the next morning to continue our march.
