I fully expected the next moment to see the huge claws of a monstrous grizzly as he worked his way down to us, when, instead of a growl, I heard the whine and sharp bark of a dog.  It was the voice I felt sure, of our faithful Pilot, whom we had left at our last camp, as we supposed, on the point of death.  I called out his name, and he answered with a joyous bark.  Presently we saw him looking down upon us, when, satisfied that we were really there, he gave another bark, and then Red Squirrel, who had clambered up to the surface, told me that he was scampering away to the southward.  I tried to get out to watch him, but was utterly unable to accomplish the task, and Red Squirrel himself was too weak to help me.  I felt sure, however, that the dog had gone to summon our friends.  I tried to cheer up poor Hugh with the news.  He seemed scarcely able to understand what had occurred, and I became greatly alarmed at his condition.
