The sun that I had half longed for, half looked forward to with terror, at last rose. My condition, as the heat went on increasing, became more dreadful; and I crawled around, changing every moment my position, in order to enjoy the little shade afforded by the leafless branches of the tree. About noon there was of course scarcely a spot of shade left—only enough for my head,—and I suffered greatly from the pangs of thirst, although I sucked a little of my blood till I became senseless, and fell into a sort of delirium, from which I only recovered when the sun went down behind the mountains. I then regained some consciousness, and crawled out of the shade of the tree, throwing a melancholy glance over the plain, when suddenly I heard the cry of a camel. It was the most delightful music I ever heard in my life; and raising myself a little from the ground, I saw a mounted Tarki passing at some distance from me, and looking eagerly around. He had found my footsteps in the sandy ground, and losing them again on the pebbles, was anxiously seeking traces of the direction I had taken. I opened my parched mouth, and crying, as loud as my faint strength allowed, “áman, áman” (water, water), I was rejoiced to get for answer “íwah! íwah!” and in a few moments he sat at my side, washing and sprinkling my head, while I broke out involuntarily into an uninterrupted strain of “el hamdu lilláhi! el hamdu lilláhi!” Having thus first refreshed me, and then allowed me a draught which, however, I was not able to enjoy, my throat being so dry, and my fever still continuing, my deliverer, whose name was Musa, placed me upon his camel, mounted himself in front of me, and brought me to the tents. They were a good way off. The joy of meeting again, after I had been already despaired of, was great; and I had to express my sincere thanks to my companions, who had given themselves so much trouble to find me. But I could speak but little at first, and could scarcely eat anything for the next three days, after which I gradually recovered my strength. It is, indeed, very remarkable how quickly the strength of a European is broken in these climes, if for a single day he be prevented from taking his usual food. Nevertheless I was able to proceed the next day (the 17th), when we kept more towards the slope of the Akakús, and here passed a broad lateral valley, rich in herbage, called Ádar-n-jelkum, after which we descended about a hundred feet from the pebbly ground into sandy soil forming a sort of valley called Ighelfannís, and full of ethel-trees and sebót. In such a locality we encamped two hours after noon, near splendid ethel-trees; but the strong north-easterly wind, enveloping ourselves and baggage in thick clouds of sand, banished all enjoyment.
