fur. His tail he spreads out behind and uses it as a rudder while he falls slowly and gracefully.
Once when John Burroughs was traveling in Mexico he was much impressed with the stories that the natives told him about the ability of the black Mexican squirrel to jump from a great height. The naturalist scoffed at the natives so much that they finally tried an experiment for his benefit. A black squirrel was caught and taken in a bag to the top of a cliff which fell sheer for five hundred feet. They opened the mouth of the bag, while a man stood on either side of it to prevent the squirrel's escape in any way but by jumping. The squirrel looked first at one of his captors and then at the other, and then over the side of the cliff. Without a second's hesitation he took the leap. He was six or eight seconds making the descent, striking gracefully upon a rock. He did not seem to be in the slightest degree injured by his long jump. Any other quadruped, with the exception of the flying squirrel, would have been pounded to jelly.
