The beaver and the bear are often benefited by the deep snows which afflict their wild neighbors. During the prolonged hibernating sleep, the bear does not eat, but he commonly needs a thick snowy blanket to keep him comfortable. The beaver has his winter stores on the bottom of the pond beneath the ice. These he reaches from his house by swimming beneath the ice from the house to the food-pile. If the ice is not covered by snow, it may, during a cold winter, freeze thickly, even to the bottom, and thus cause a starving time in the beaver colony. Deep snow appears not to trouble the "stupidest animal in the woods," the porcupine. A deeper snow is for him a higher platform from which the bark on the tree may be devoured. Rabbits, too, appear to fare well during deep snow. This uplift allows them a long feast among the crowded, bud-fruited bush-tops at which they have so often looked in vain. The chipmunk is not concerned with groundhog day. Last summer he filled his underground granaries with nuts and seeds, and subways connect his underground winter quarters with these stores. But heavy snows, with their excess of water, flood him out of winter quarters in spring earlier than he planned. One March at the close of a wet snow-fall I went out into a near-by pine grove to see the squirrels. One descended from a high hole to the snow and without trouble located and bored down through the snow to his cone-deposit. With difficulty he climbed up through the heavy snow with a cone. He did not enjoy floundering through the clinging snow to the tree-trunk. But at last up he started with a snow-laden cone, in search of a dry seat on which to eat. After climbing a few feet he tumbled back into the unpleasant snow. In some manner the wet snow on the tree-trunk had caused his downfall. With temper peppery he gathered himself up, and for a moment glared at me as though about to blame me for his troubles. Then, muttering, he climbed up the tree. Sometimes the chipmunk, and the squirrel also, indulge in hibernating periods of sleep despite their ample stores of convenient food. The ptarmigan is preëminently the bird of the snows; it is the Eskimo of the bird world. It resides in the land realm of the Farthest North and also throughout the West upon high mountain-tops. In the heights it lives above the limits of tree growth, close to snow-drifts that never melt, and in places above the altitude of twelve thousand feet. It is a permanent resident of the heights, and apparently only starvation will drive it to the lowlands. Its winter food consists of seeds of alpine plants and the buds of dwarf arctic willow. This willow is matted, dwarfed, and low-growing. When drifted over, the ptarmigan burrow into the snow and find shelter beneath its flattened growth. Here they are in reach of willow buds.
