He was unwilling to think of what he would do if the cleft now suddenly came to an end; the thought occurred to him constantly, but he thrust it aside, and went on steadily. But he knew it could not be for long.

Where the cleft was more than usually narrow, he set his back against one side, and hands and feet against the other, carefully hoisting himself up and making sure of his hold with one foot and hand before moving the other. Where it was wider, or almost disappeared, he clung tightly to the side, testing the rocky points that jutted out before trusting his weight to them. At times he had but just time to get a grip with his hands, when his foothold gave way. Then, clinging tightly with his fingers, he had to feel about with his feet for a rest before shifting his grip. Inch by inch, by the exercise of all his strength and all his will, he climbed on, until at last he reached a ledge that allowed him a much-needed rest. He looked down at the way he had come, but the sight made him dizzy, and he hastily averted his eyes. It seemed incredible that he should have come up there; from where he was, the rock seemed to fall away inwards beneath him. He determined not to look back again; he felt that if he did so he would never reach the top. He turned instead to a scrutiny of the way before him.

A cold sweat broke out on him as he realized that the cleft he had been climbing ran but some ten or twelve feet more, making perhaps a sixth part of the height.

But the ledge, he remembered, continued to the left, in a series of jutting crags, until it reached another vertical cleft running right to the top. One thing was clear: it would be impossible to pass along the ledge with the rope coiled round his body; the path was far too narrow, and if the rope should catch on any projecting point he would be thrown off his balance.

Another thing was borne in upon him now—that to think overmuch about the task before him was more dangerous than all else. Without more ado, he loosened the rope and let one end fall, fastening the other carefully to the rock on which he was seated.

Where it was possible to get along the ledge, it would surely be possible to come back the same way, he thought. It was only in the actual descent that the difficulties were greater. And if he came to any point that was absolutely impassable, he could always give it up and return—“Perhaps,” he added, with emphasis.

Little by little he made his way along the ledge, depending at times upon the grip of his hands alone, with his body entirely unsupported. First a firm grip with the one hand and then a careful search with the other for a fresh hold. All his thoughts were concentrated upon his hands and their hold. When at length he had reached the flat rock that he had been making for, he found himself exhausted for the moment. He closed his eyes, and allowed his whole body to relax for a brief respite.

It gave him some relief; when he opened his eyes again, he felt as if he had slept. Once more he recommenced his perilous way, creeping carefully and with every nerve strained, to the next projecting rock. This brought him to the commencement of the upward cleft he had in mind. The first part was an easy slope, and could be managed well enough; higher up, however, it grew steeper. Ørlygur realized that, even if he succeeded in getting up, it would be almost impossible to get down again. For a moment he considered whether it would not be better after all to go back for the rope, but he gave up the idea at once. The passage along the ledge was one he felt he had not strength now to repeat. And with the rope round his body it would mean almost certain disaster to attempt it. Losing no time in further reflection, he started up the cleft.

At first all went well. Then came a stretch of smooth rock rising straight up on either side. The slightest false move here would be fatal, and there were some ten or twelve feet of it to be covered. How he managed it, he never quite knew, and from this point onwards he moved unconsciously, knowing nothing of his own progress until he found himself lying, exhausted and breathless, at the summit. His clothes were torn, his hands bleeding and bruised, and there was a cut on one knee. The keen mountain air refreshed him, and he lay quietly drinking it in before rising to his feet. He remembered now how he had been on the point of slipping at that last stretch of smooth rock, and, nerved by fear, had made a superhuman effort. It had been muscle acting without brain, for his mind had been a blank at the time. But it was done now. After that terrible moment, the last part of the way had been easier, and he had not stopped to think.

After resting for a little, he went to the edge and peered over. Now that he was here, he felt no sensation of dizziness as when he had looked down before. But it was evident beyond doubt that it would be certain death to attempt to descend by the way he had come.
