I was confronted with this problem: whether it was better to enjoy life for a few days, sleeping and eating my fill until the provisions gave out, or to "plug on" again in hunger with the prospect of plunging at any moment into eternity without the great luxury and pleasure of food. And then an idea presented itself which greatly improved my prospects. It was to construct a ladder from alpine rope; one end of which was to be secured to the bow of the sledge and the other to be carried over my left shoulder and loosely attached to the sledge harness. Thus, if I fell into a crevasse again, it would be easy for me, even though weakened by starvation, to scramble out again by the ladder, provided the sledge was not also engulphed. Notwithstanding the possibilities of the rope ladder, I could not sleep properly at all; my nerves had been so overtaxed. All night considerable wind and drift continued. On the 19th it was overcast and light snow was falling. I resolved "to go ahead and leave the rest to Providence." As they wallowed through the deep snow my feet and legs kept breaking through into space. Then I went right under, but the sledge was held back and the ladder "proved trumps." A few minutes later I was down again, but I emerged again without much exertion, half-smothered with snow. Faintness overcame me and I stopped to camp, though only a short distance had been covered. All around me was a leaden glare, the snow clouds "corralling" me in. The sun had not shown up for some days and I was eager to see it once more, not only that it might show up the landscape, but for its cheerful influence and life-giving energy. A few days previously my condition had been improving, but now it was going back. During the night of the 18th loud booming noises, sharp cracks and muffled growls issued form the neighbouring crevasses and kept waking me up. At times one could feel a vibration accompanying the growling sounds, and I concluded that the ice was in rapid motion. The sun at last appeared on the 19th, and I was off by 8.30 A.M. The whole surface was a network of crevasses, some very wide. Along one after another of these I dragged the sledge until a spot was reached where the snow-bridge looked to be firm. Here I plunged across, risking the consequences. After three hours' marching nothing serious had happened and I found myself on safer ground with a "pimply" surface visible ahead, close under the slopes of the highlands. Once on this I became over-reliant, and in consequence sank several times into narrow fissures. At 1 P.M. the Mertz Glacier was at last crossed and I had reached the rising hills on its western side. Overlooking the camp, five hundred feet above the glacier, were beetling, crevassed crags, but I could trace out a good road, free from pitfalls, leading to the plateau, at an elevation of three thousand feet.
