In order to move more quickly, Mr. Finch and Captain Bruce dispensed with the rope. The rocks were quite easy, and at 26,500 feet they had passed two admirable sites for a camp. But the wind was steadily increasing in force, and they were compelled to leave the ridge and traverse out across the great north face. This was bad luck, for the ridge was easy climbing and the face was not. The stratification of the rocks was most awkward, and it was hard to find any good footholds. The climbers were unroped, and it was a severe test of Captain Bruce, who had had no mountaineering experience to give him confidence. Sometimes they were on treacherous slopes, sometimes on more treacherous snow, and they often had to cross heaps of scree that moved with every step. They stopped occasionally to replace an empty cylinder of oxygen with a new one, each of which meant five pounds off their load. Presently the aneroid gave their height as 27,000 feet. They now ceased traversing, and began to climb straight upward to a point on the North-East ridge, half way between the shoulder and the summit. Soon they were at 27,300 feet, and the top of Everest was the only mountain they could see without looking down. The peaks which had seemed so formidable from the glacier had now sunk into insignificant humps. They were 1,700 feet below the summit, well within half a mile of it, and they could distinguish stones and a patch of scree just under its highest point. But it was very clear that they could go no farther. Weak with hunger and the anxiety and labours of the past forty-eight hours, it was plain to Mr. Finch that if they went on even for another 500 feet they would not both get back alive. Like wise and brave men they decided to retreat. It was now about midday, and for greater safety they roped together. At first they followed their old tracks, and then moved towards the North ridge at a point higher than where they had left it. They reached the ridge at two o'clock, and there reduced their burden by dumping four oxygen cylinders at a place to which future climbers could be directed.
