Animals at Rest
Wild animals asleep fall into graceful attitudes. The fox curls himself up with all the luxurious air of a cat; he rests his head in the lap of two front pads, then twines his brush neatly round over his long, pointed nose. He is a light sleeper; but hares and rabbits are still more easily roused. We believe hares sleep with their eyes wide open; the uncapped lenses of the eyes remain active through sleep, so that any vision of danger conveys an automatic alarm to the brain. People are sometimes puzzled when, in open fields, they notice a dozen or more hare forms or beds within a few yards of each other. They may conclude that hares swarm in those fields. Probably the reason for the many forms is that a hare likes to face the wind when sleeping, and so scratches out many beds to suit the wind's changing directions. Among animals that sleep very soundly is the hedgehog—he has little to fear when asleep; in case of danger, he has only to erect his spines, to discourage effectively any disturber of his dreams. While hedgehogs, dormice, and badgers sleep deeply through the greater part of the winter, the squirrel is the lightest of sleepers; on dry, bright winter days he enjoys a frolic in the snow.
