high-mountain work had not yet been taken to the cache, and our pemmican, erbswurst, chocolate, compressed tea, and figs were safe. But it was a great blow to us and involved considerable delay at a very unfortunate time. We felt mortification at our carelessness as keenly as we felt regret at our loss. The last thing a newcomer would dream of would be danger from fire on a glacier, but we were not newcomers, and we all knew how ever-present that danger is, more imminent in Alaska in winter than in summer. Our carelessness had brought us nigh to the ruining of the whole expedition. The loss of the films was especially unfortunate, for we were thus reduced to Walter's small camera with a common lens and the six or eight spools of film he had for it. [Illustration: Hard work for dogs as well as men on the Muldrow Glacier.] [Sidenote: Camping Comfort] The next day the final move of the main camp was made, and we established ourselves in the cirque at the head of the Muldrow Glacier, at an elevation of about eleven thousand five hundred feet, more than half-way up the mountain. After digging a level place in the glacier and setting up the tent, a wall of snow blocks was built all round it, and a little house of snow blocks, a regular Eskimo igloo, was built near by to serve as a cache. Some details of our camping may be of interest. The damp from the glacier ice had incommoded us at previous camps, coming up through skins and bedding when the tent grew warm. So at this camp we took further precaution. The boxes in which our grub had been hauled were broken up and laid over the whole portion of the floor of the tent where our bed was; over this wooden floor a canvas cover was laid, and upon this the sun-dried hides of the caribou and mountain-sheep we had killed were placed. There was thus a dry bottom for our bedding, and we were not much troubled thenceforward by the rising moisture, although a camp upon the ice is naturally always a more or less sloppy place. The hides were invaluable; heavy as they were, we carried them all the way up. So soon as we were thus securely lodged, elated when we thought of our advance, but downcast when we recalled our losses, we set ourselves to repair the damage of the fire so far as it was reparable. Walter and Johnny must go all the way down to the base camp and bring up sled-covers out of which to construct tents, must hunt the baggage through for old socks and mitts, and must draw upon what grub had been left for the return journey to the extreme limit it was safe to do so.
