"The sooner the better, sir," said the sentry; and we went on as far as the next sentry, passing the stones where we had sat to sun ourselves. We talked with this second man about the Boers, received a similar account of the proceedings of the enemy, said "Good-night," and then strolled back to the stones, to sit down for a few minutes, my heart beating harder than ever. "Now," said Denham at last, in a low tone of voice; "off with your rope, and give me one end. I'll make your line fast to mine, while you secure the other end to that big stone. Tight, mind; I don't want to fall sixty feet and break my neck." "Nor I," was my reply. "Be sure of your knot, too." "Right." Then, in the silence, we each did our part of the task, ending by Denham letting the strong thin rope glide over the edge of the great stones which formed the breastwork. The next minute we stood listening to the sounds from the court, and narrowly watched for our sentries. Far out in the darkness a feeble light or two showed where a lantern burned in the Boer lines. Everything seemed to favour our design, even to the end, and I was breathing hard with excitement, waiting to begin. Just then a hand touched my arm and glided down over my wrist. I knew what it meant, and grasped Denham's hand. "Good luck to us!" he whispered. "I'll go first and test the rope-- hush! I will. As soon as I'm down I shall lie flat and hold on. Ready?" "Yes." "Off!" CHAPTER FORTY ONE. OUR WILD ATTEMPT. Denham's words sounded so loud that, as I dropped on one knee to hold the knot of the rope round the stone to prevent it from slipping, I felt sure that the sentries to right and left must have heard him speak. But it was only due to my excited way of looking at things. For the next minute, after a preliminary rustling, I felt a peculiar thrill run along the hide rope. This went on while I wondered if my companion had made the joining of the two ropes secure, my imagination working so rapidly that I seemed to see the knot stretching and yielding till one of the ends slipped through the loop of the knot, and-- The thrilling sensation had ceased; and the rope, which felt in my hands like some living, vibrating thing, hung loose. The next moment a kink ran up it and dissolved in my hands. It was Denham's way of saying "All right," and I knew my turn had come.
