nights we camped on the bare granite rock before we reached the limit of the bay. All vegetation had disappeared; hardly a bunch of grass was seen. The only signs of former life were the sodden and splintered spruce and fir stumps that projected here and there from the bases of huge gravel heaps, the moraine matter of the mighty ice mass that had engulfed them. They told the story of great forests which had once covered this whole region, until the great sea of ice of the second glacial period overwhelmed and ground them down, and buried them deep under its moraine matter. When we landed there were no level spots on which to pitch our tent and no sandy beaches or gravel beds in which to sink our tent-poles. I learned from Muir the gentle art of sleeping on a rock, curled like a squirrel around a boulder.
