342 THE EMPTY QUARTER greater than mine. If I could do without that, they surely could; and the moment was rapidly approaching when I could no longer keep awake in the saddle, while the camels, driven on by Zayid as if the fiend himself was behind them and responding nobly to the heel, were almost at the end of their powers of endurance. Furthermore there was not the slightest hope of fodder even if we came to fuel. About 9 p.m. I sounded Salim and Humaid and was not less surprised than pleased to find them in agreement with my view, that it was useless seeking fuel in that darkness without any idea whatever of its whereabouts or distance. Like that we might go on all night without success, and our last state would be worse than our first. Let us rest the night and sleep, I said, for even the hungry camels will be better to-morrow for a rest now. Yes, added Abu Ja'sha, and the camels are dead, but Zayid drives on as you see. Look you, I said, I can go on no more without sleep. If any of you know of fuel within five minutes or ten, let him lead on. Otherwise I will halt here and you may do as you will. So, with considerable relief I thought, the cry went up that Shaikh 'Abdullah was weary and would halt. Back from the front came sounds of voluble cursing and Zayid reined up to protest at the folly of halting. It is but folly, I rejoined very curtly as I tapped Na'riya to her knees, it is but folly to march on blindly you know not whither. I march no more, and here I sleep. You are the Amir and can please yourself. There may be fuel near or far, within five minutes or five hours. Seek it out as you please and I will come to you when you have found it. I can follow your tracks in the daylight to-morrow, but I can sit on a camel no more. So with a muttered curse Zayid yielded, and the unfor- tunate camels came to rest at 9.15 p.m. after a forced and furious march that had begun soon after midnight. Out of the 21 hours they had actually marched 18 allowing for the occasional short halts we had enjoyed, and the distance we had covered in the time was about 70 miles. The wretched animals just stretched out their necks on the cool sand and remained motionless, while we unloaded the gear and spread our beds on the desert for a well-earned rest.
