Being already fatigued, the disappointment, of course, depressed my spirits, and I had to summon all my resolution and energy in order to descend into the ravine and climb the other side. It was now past ten o’clock; the sun began to put forth its full power, and there was not the slightest shade around me. In a state of the utmost exhaustion I at length reached the narrow pinnacled crest, which was only a few feet broad, and exhibited neither inscriptions nor sculptures. I had a fine prospect towards the south-west and north-east, but I looked around in vain for any traces of our caravan. Though exposed to the full rays of the sun, I lay down on my high barbacan to seek repose; but my dry biscuit or a date was quite unpalatable, and being anxious about my little provision of water, I could only sip an insufficient draught from my small water-skin. As the day advanced I feared that our little band, thinking that I was already in advance, might continue their march in the afternoon, and, in spite of my weakness, determined to try to reach the encampment. I therefore descended the ravine, in order to follow its course, which, according to Hatíta’s indications, would lead me in the direction of the well. It was very hot, and being thirsty, I swallowed at once the little water that remained. This was about noon, and I soon found that the draught of mere water, taken upon an empty stomach, had not at all restored my strength. At length I reached the bottom of the valley. Hatíta had always talked as if they were to encamp at no great distance from the mountain; yet, as far as I could strain my view, no living being was to be seen. At length I became puzzled as to my direction, and hurrying on as fast as my failing strength would allow, I ascended a mound crowned with an ethel-bush, and fired my pistols; but I waited in vain for an answer: a strong east wind was blowing dead against me. Reflecting a moment on my situation, I then crossed the small sand-hills, and, ascending another mound, fired again. Convinced that there could be nobody in this direction, at least at a moderate distance, I bethought myself that our party might be still behind, and, very unluckily, I kept more directly eastward.
