At length, the cattle and flocks having been driven in advance, we started, and, leaving the vale, ascended elevated rocky ground, from which, following a south-westerly direction, we descended, a little before two o’clock in the afternoon, into the narrower eastern part of a deep and beautiful valley, which here is adorned by a pretty grove of date-trees, while its western part expands into fine cultivated ground. Here we made a halt of about half an hour, in order to water the animals and replenish our skins; for not even here was it thought advisable to encamp, as it is regarded as a very inauspicious place, this being the spot where, in 1850, the Kél-owí fell upon the Welád Slimán and almost exterminated them. After so short a halt we again pursued our march. I was now so totally exhausted that I was obliged to dismount at short intervals and lie down for a moment; and once, when left alone, it was only with the utmost exertion that I was able to mount my horse again; but nevertheless I managed to drag myself along. At length, about sunset, we chose a place for our encampment on the brow of the slope descending into a deep valley. Having now been thirty-four hours on horseback with only short and insufficient intervals, I fell senseless to the ground, and was considered by Mr. Overweg and our people as about to breathe my last. But after an hour’s repose I recovered a little, and, having had a good night’s rest, felt myself much stronger on the following morning, so that I could even undergo some exertion which was not exactly necessary.
