The Rabbit. â â⢠Living rabbits may be kept in the Schoolroom in a box open at one end, the open end protected by a door covered with wire screen- ing. A rabbit thus kept, if given a little care, soon becomes accustomed to his surroundings and will prove a very acceptable addition to the laboratory. Adaptations to Its Life. â The rab- bit in a wild state makes its home under clumps of dried grass, brush, and the like. Its English cousins make burrows in the ground. The rabbit escapes observation from its enemies by means of its color, which often closely resembles that of the thickets in which it hides. Notice the body covering; is it uniform in color and thickness? The hair forms a protec- tion from the cold. In summer the color of the coat is more earthlike than in the winter. Some arctic forms un- dergo a complete change of coat from gray in summer to white in the winter. Compare the fore limbs of the rab- bit with your own arms; do you find upper arm, forearm, wrist, and hand? In the same manner find the parts corresponding to thigh, shank, and foot in your own leg. Notice the differ- ent methods of locomotion in the rabbit; seek the ways in which the limbs of the rabbit are adapted to the function of locomotion. Notice the feet to see if they are adapted for digging or for any other purpose. The rabbit relies principally on swiftness and agility in flight rather than in ability to cope with an enemy with teeth and claws. Frequently they will remain in absolute quiet, allowing their arch-enemy, the dog, to pass close to them, relying on their protective coloration to escape notice. When chased bj^ the dog, they have the instinct of running in a circle and will during the chase suddenly jump to one side at a sharp angle in order to throw the dog off the scent. The
