At one point it seemed that we should be obliged to return to the summit and try the other way down. We were on the very edge of the arête. On one side was the enormous precipice facing the Pelvoux, which is not far from perpendicular; on the other a slope exceeding 50°. A deep notch brought us to an abrupt halt. Almer, who was leading, advanced cautiously to the edge on hands and knees, and peered over; his care was by no means unnecessary, for the rocks had broken away from under us unexpectedly several times. In this position he gazed down for some moments, and then, without a word, turned his head and looked at us. His face _may_ have expressed apprehension or alarm, but it certainly did not show hope or joy. We learned that there was no means of getting down, and that we must, if we wanted to pass the notch, jump across on to an unstable block on the other side. It was decided that it should be done, and Almer, with a larger extent of rope than usual, jumped. The rock swayed as he came down upon it, but he clutched a large mass with both arms and brought himself to anchor. That which was both difficult and dangerous for the first man was easy enough for the others, and we got across with less trouble than I expected; stimulated by Croz’s perfectly just observation, that if we couldn’t get across there we were not likely to get down the other way. We had now arrived at *C* and could no longer continue on the arête, so we commenced descending the face again. Before long we were close to the schrund, but unable to see what it was like at this part, as the upper edge bent over. Two hours had already passed since leaving the summit, and it began to be highly probable that we should have to spend a night on the Glacier Blanc. Almer, who yet led, cut steps right down to the edge, but still he could not see below; therefore, warning us to hold tight, he made his whole body rigid, and (standing in the large step which he had cut for the purpose), had the upper part of his person lowered out until he saw what he wanted. He shouted that our work was finished, made me come close to the edge and untie myself, advanced the others until he had rope enough, and then with a loud _jödel_ jumped down on to soft snow. Partly by skill and partly by luck he had hit the crevasse at its easiest point, and we had only to make a downward jump of eight or ten feet.
