It was not necessary to mount much, for we were almost as high as the mouth of the cave, according to Christian's belief, and our work consisted chiefly in passing along the face of the rock, round projecting buttresses and re-entering angles, till we reached that part of the mountain where we might expect to find our glacière. While we were thus engaged, two hoarse and ominous ravens took us under their charge, and accompanied us with unpleasant screams, which argued the proximity of food or nest. We soon found that we had disturbed their meal, for we came to marks of blood, and saw that some animal had slipped on the rocks above, and landed on the ledge on which we were walking, bounding off again on to a shelf below, where the ravens had already torn the body to pieces. I must confess to a very considerable shudder when we discovered the reason of their screams, and neither of us seemed to enjoy the circling and croaking of the unclean birds. Very soon after this, Christian announced that we had reached the cave, and a steep little climb of six feet or so brought us to the entrance. Here we were haunted still by the presence of pieces of the fallen goat, which lay about here and there on the ground; and the flutter of wings overhead explained to us that the old ravens had built their nest in the mouth of the cave, and had brought morsels of raw flesh to their young ones, which were scarcely able to fly. I am ashamed to say that we were so angry with the old birds for shrieking so suggestively in our ears, and parading before us the results of a slip on the rocks, that we charged ourselves with stones, and put an end to the most noisy member of the foul brood; Christian making some of the worst shots it is possible to conceive, and raining blocks of stone and lumps of wood in all directions, with such reckless impartiality, that the only safe place seemed to be between him and the bird. One of us, at least, regretted the useless cruelty as soon as it was perpetrated, and it came back upon me very reproachfully at an awkward part of our return journey.
