On the way home one winter afternoon I came upon a beaver colony a little below timberline. In the edge of the woods I stood for a time looking out on the white smooth pond. Lines of tracks crossed it from every point of the compass. Two camp birds alighted on a tree within a few feet and looked me over. I heard a flock of chickadees going through the woods. A lynx came out of the willow clumps on the opposite shore. He walked out on the snowy pond and headed straight for the house. He was in no hurry and stepped slowly along and climbed on top of the house. Here he sniffed a time or two, then raked the house with right forepaw. He sniffed again. Nothing in reach for him. Climbing down off the beaver house the lynx walked around it and started for the woods near me. Catching my scent he stopped, took a look, then went full speed into the Engelmann spruce forest. Other lynx had visited the top of the beaver house and also prowled along the bottom of the dam. A number of mountain sheep had crossed the pond a day or two before. The pond was in a deep gulch and a goodly stream of water out of sight beneath the ice and snow was running into it. The concentrated outflow burst out over the top of the south end of the dam through an eighteen-inch opening. This pond was frozen over for five months. For these five months the beaver each day had a swim or two in the water under the ice. When hungry he took a section of an aspen from the pile on the bottom of the pond. This was dragged under the ice up into the house, where it afforded a meal of canned green bark. Most summer birds fly away from winter. Other birds and a few animals travel a short distance--go to a place where food is more abundant although the winter there may not be any milder than in the locality in which they summered. Birds that remain to winter in the locality in which they summered, and most of the animals, too, go about their affairs as usual. They do not store food for the winter or even for the following day. The getting of food in the land of snows does not appear to trouble them. But a number of animals--squirrels, chipmunks, conies, and beavers--store food for the winter. Generally these supplies are placed where they are at all times readily reached by the owners; on the earth, in it, in the water; the place depending on the taste and the habits of the fellow. Upon the mountain tops the cony, or Little Chief Hare, stacks hay each autumn. This tiny stack is placed in the shelter of a big boulder or by a big rock, close to the entrance of his den. While the beaver is eating green canned bark the cony is contentedly chewing dry, cured hay. The beaver is one of the animals which solves the winter food and cold problem by storing a harvest of green aspen, birch, and willow. This is made during the autumn and is stored on the bottom of the pond below the ice-line. Being canned in cold water the bark remains fresh for months.
