All along this crest went a snakelike long crevasse, for which we had continually to sound, and go first one side and then the other; then we got to the foot of the saddle. Some twenty or thirty steps, some cut, some uncut, soon took us up a kind of hollow, and we got on a little sloping plateau of some large, where we left the grub and the knapsack, keeping my small flask of cognac only. Then up a steep ice slope, very steep I should say, down which the bits of ice cut out of the steps hopped and jumped at full gallop and then bounded over to some bottomless place which we could not see down. Their pace gave one an unpleasant idea of the possible consequence of a slip.
