The face of the glacier had undergone much change. Blocks of immense size had broken from it, and lay strewn over the valley at its base; while the glacier itself had pressed down the slope, crowding rocks, and snow, and the _débris_ of ice before it in a confused, wave-like heap. The progress toward the sea had been steady and irresistible. The journey to the top of the glacier was much more difficult than in the previous autumn, the snow having in a great measure melted away, exposing the rocks, and embarrassing us in the ascent of the glacier's side, as well as of the gorge. Every thing was wet and mucky, overhead as well as under foot. The glacier-surface was shedding water from every side, like the roof of a house in a February thaw; and the little streams which flowed down its side, joining the waters of the melting snow, trickled underneath the glacier and reappeared in rushing torrents in the valley below from the glacier front; and thence poured into the lake, and from the lake to the sea. I was fortunate in finding my stakes all standing; and, having brought up the theodolite, I repeated the angles which, with Sonntag, I had taken the previous October. These angles, when afterwards reduced, exhibited a descent of the centre of the glacier, down the valley, of ninety-six feet. [Sidenote: THE MUSK-OX.] Chester Valley has in former times been quite a resort of the Esquimaux. We found there several old ruins of huts, some of them with bones strewn about them, which showed that they were not of very ancient date. Among these bones, which were mostly of the walrus, seal, and bears, I found a part of the head of a musk-ox, and in such a position as appeared to render it probable that the animal of which it had formed a part had been the food of the former inhabitants of the ruin. Upon referring the matter to Kalutunah, he told me that the musk-ox was supposed to have been once numerous along the entire coast, and that they are still occasionally seen. No longer ago than the previous winter, a hunter of Wolstenholme Sound, near a place called Oomeak, had come upon two animals and killed one of them. It would seem from this circumstance that the musk-ox is not yet extinct in Greenland, as naturalists have supposed. One day of my stay in the valley was occupied with running a set of levels down from the foot of the glacier to the sea, by which I found the former to be ninety-two feet above the latter; and another day was passed in hunting.
