What the time was, or how long it had taken those one hundred and thirty-seven camels to pass through the gap, I had no idea; but the sun was already slanting downwards in the west and was no longer lighting the rocks at the bottom of the "coffee-cup". In fact they had disappeared for some time in the shadow cast by the ridge on which we were hidden, and as the sun gradually sank, so did the sharply-outlined shadow of the ridge and the gap, rising upwards along the opposite face of the chasm, gradually shade the zigzag path higher and higher.

We were fearfully thirsty, but we still dared not shift our cramped positions to get at our water-bottles and make ourselves more comfortable. We simply lay where we were, peering through our loopholes between the rocks at the caravan crawling down the path. Vultures, perched on the rocks around us, craned their bare necks downwards and watched too. It looked like some huge centipede or caterpillar, as each camel carefully felt for his next foothold and swung his long ungainly legs stiffly and cautiously forward. I caught sight of one, the third in a gang or string of five, evidently making very "heavy weather" of it. Whenever the path was sufficiently broad I noticed that an Arab would take hold of his halter to steady him. I pointed out this camel to Jaffa, and scarcely had he whispered: "He fall—soon," when the poor brute stumbled, tried to recover his feet, and fell on one knee, the other leg sprawling over the edge, violently pawing space. The Arab guiding him sprang away, clinging to the rocks, and in a moment the camel had toppled over. I heard wild cries of alarm; the camel leaders on the zigzag below tried desperately to make a gap in their line as they saw what was happening over their heads; but too late. The camel fell; the two camels behind were dragged after him, and the three slid like an avalanche down the rocks, sweeping more camels and one or two Arabs from the narrow zigzags below, bursting their bundles and scattering rifles until they disappeared in the gloom beneath.

It was a horrid sight, and for two or three minutes there was the utmost confusion. The frightened drivers pulled the camels' heads this way and that, and how the poor stupid creatures could keep their foothold at all was marvellous, especially as in many places the path was so narrow that, even from where I was, I could see the "inner" bundles of rifles scraping against the rocks.

We were so intent on watching this that we never turned our heads; but when I did again look across the gap to see whether Webster and his men were still hidden, I had a terrible fright.

Squatting right in the mouth of the gap, and on both edges of it, were a score or more of Arabs, their rifles slung over their shoulders. Jaffa saw them; Griffiths saw them. If they were as frightened as I was they did not show it.

We hardly dared to breathe. There they were, the nearest of them not fifty yards away. They evidently meant to stay, for they had brought firewood, and some of them were trying to set light to it, whilst others were pouring water from a skin into a brass cooking pot.

That anything such as this should happen had never entered my head. I never thought that they would have taken the precaution of leaving a rearguard to protect their line of retreat, and to have done so entirely altered the whole situation and upset all my calculations.

If they took to wandering along that ridge we should be discovered, and if they simply remained where they were we could not fire on the caravan without exposing ourselves to this new force. At the very first shot they would take cover, find out where we lay, and then crawl to the rocks overhead and shoot down. In those first few moments my whole idea was to kill as many as possible before being killed myself.

We watched them with straining eyes. If they had scattered and come near us I should have opened fire. My fingers clutched my rifle to draw it to me, and then loosened again, because they all collected round that cooking pot; the blue smoke came curling up among them, and they evidently had no other thought than to rest and make coffee. They never even troubled to look down to see whether their comrades and the camels were recovering from their disorder, but huddled close together, sheltering their heads from the sun with their dirty cloaks.

There was no immediate danger, so I turned to watch the caravan. Down at the gloomy bottom of the "coffee-cup" I could just distinguish little white figures moving among the boulders—-the advance party had at last reached the gorge which led them out into the open. Three or four disappeared round the shoulder of the rocks which shut out my view of the gorge, and I knew that in a moment or two they would sight the Intrepid lying at anchor—and perhaps her advancing men.
