_Hesperomys_ is the rather woodsy name of the white-footed or deer-mouse, a shy, timid little creature dwelling in every wood, who, notwithstanding his abundance, is an utter stranger to most of us. We are more familiar with his tracks, however, than with even those of the squirrel and rabbit. His is that tiny double trail galloped across the snowy paths in the woods. We see them sprinkled over the snow everywhere; but when have we seen the feet that left them? Here goes a line of the wee prints from a hole in the snow near a stump over to the butt of a large pine. Whitefoot has gone for provender to one of his storehouses among the roots of the pine; or maybe a neighbor lives here, and he has left his nest of bird-feathers in the stump to make a friendly call after the storm. A bed of downy feathers at the heart of a punky old stump beneath the snow would seem as much of a snuggery as ever a mouse could build; but it is not. Instead of a dark, warm chamber within a hollow stump, Whitefoot sometimes goes to the opposite extreme, and climbs a leafless tree to an abandoned bird's nest, and fits this up for his winter home. Down by Cubby Hollow I found a wood-thrush's nest in a slender swamp-maple, about fifteen feet from the ground. The young birds left it late in June, and when Whitefoot moved in I do not know. But along in the winter I noticed that the nest looked suspiciously round and full, as if it were roofed over. Perhaps the falling leaves had lodged in it, though this was hardly likely. So I went up to the sapling and tapped. My suspicions were correct. After some thumps, a sleepy, frightened face appeared through the side of the nest, and looked cautiously down at me. No one could mistake that pointed nose, those big ears, and the round pop-eyes so nearly dropping out with blinking. It was Whitefoot. I had disturbed his dreams, and he had hardly got his wits together yet, for he had never been awakened thus before. And what could wake him? The black-snakes are asleep, and there is not a coon or cat living that could climb this spindling maple. Free from these foes, Whitefoot has only the owls to fear, and I doubt if even the little screech-owl could flip through these interlaced branches and catch the nimble-footed tenant of the nest.
