The stream we were steering for was reached.  Travelling over the ice, we were soon again in a region where the snow lay thicker than ever, and it became very trying to our dogs.  Our special favourites, Whiskey, Pilot, and Muskymote, went on bravely, in spite of their hard labour by day and the intense cold to which they were exposed by night.  They, knowing fellows, whenever they stopped, carefully picked out the snow which, getting between their toes, would have cut them severely; but some of the younger ones, not understanding the necessity of so doing, allowed it to accumulate, and became lame.
