My strength being now exhausted, I sat down on the naked plain, with a full view before me of the whole breadth of the wadi, and with some confidence expected the caravan. I even thought, for a moment, that I beheld a string of camels passing in the distance. But it was an illusion; and when the sun was about to set, not being able to muster strength enough to walk a few paces without sitting down, I had only to choose for my night’s quarters between the deserted huts and an ethel- tree which I saw at a little distance. I chose the latter, as being on a more elevated spot, and therefore scrambled to the tree, which was of a respectable old age, with thick tall branches, but almost leafless. It was my intention to light a fire, which promised almost certain deliverance; but I could not muster sufficient strength to gather a little wood. I was broken down and in a feverish state. Having lain down for an hour or two, after it became quite dark I arose from the ground, and, looking around me, descried to my great joy a large fire S.W. down the valley, and, hoping that it might be that of my companions, I fired a pistol, as the only means of communicating with them, and listened as the sound rolled along, feeling sure that it would reach their ears; but no answer was returned. All remained silent. Still I saw the flame rising towards the sky, and telling where deliverance was to be found, without my being able to avail myself of the signal. Having waited long in vain, I fired a second time—yet no answer. I lay down in resignation, committing my life to the care of the Merciful One; but it was in vain that I tried to sleep, and, restless and in a high fever, I tossed about on the ground, looking with anxiety and fear for the dawn of the next day. At length the long night wore away, and dawn was drawing nigh. All was repose and silence; and I was sure I could not choose a better time for trying to inform my friends, by signal, of my whereabouts. I therefore collected all my strength, loaded my pistol with a heavy charge, and fired—once—twice. I thought the sound ought to awaken the dead from their tombs, so powerfully did it reverberate from the opposite range and roll along the wadi; yet no answer. I was at a loss to account for the great distance apparently separating me from my companions, who seemed not to have heard my firing.
