This waiting was a tremendous strain. To know that the caravan was approaching on the other side of that ridge, behind and above us, made the longing to climb up and look over simply maddening.

To pass the time we made little loopholes between the rocks, through which we could fire towards the gap and down the zigzag path without being seen ourselves. Griffiths asked me, under his breath, if he could smoke his pipe. He asked simply to hear himself speak. He knew that I would refuse, but it was a comfort for him to whisper and a comfort for me to whisper back that the blue smoke might show—a fact he knew well enough.

Then a horrid thought struck me. When we had first reached the gap I had lighted a cigarette, and the burnt match and the end of the cigarette must be lying somewhere there still. If either of them were seen the alarm would be given at once. My whole mind became tortured with picturing them lying there on the bare stones, and I would have given anything in the world to be able to crawl across and try to find them. I did not fear that our tracks would be found: the rocks were quite bare; what loose stones there were between them would not leave a foot-mark; but even now, as the scene comes back to me, I remember that the fear of the burnt match and cigarette end being discovered was horrible at the time.

Just as the strain became almost unbearable, and the impulse to crawl to the gap almost more than I could resist—I had actually risen to my hands and knees—Jaffa gave a low sound, and pressed me down.

Looking through my loophole I saw a tall, fine-looking Arab standing erect at our side of the gap, with a rifle in his hand, turning his head from side to side and then peering below into the chasm beneath.

LOOKING THROUGH MY LOOPHOLE I SAW A TALL, FINE-LOOKING ARAB PEERING INTO THE CHASM BENEATH.

I felt certain that the white cigarette end must be lying there at his feet, and that in another second he must see it. My heart seemed to stop beating and my ears buzzed. He turned and looked intently at the very heap of boulders behind which we lay. I could have sworn that our eyes met. I had to put my hand to my mouth to prevent me giving way to the frantic desire to yell. Then he disappeared back into the gap, and I breathed more freely.

"He tell others—all safe—see nothing—camels come presently," Jaffa whispered.

In two or three minutes more Arabs—ten, then twenty—crowded through the gap, their rifles held ready and their fierce eyes scanning every rock.
