Animal Heroes

It was a good old plan--one that doubtless came from the days when Buffalo and Coyote played the parts of Cow and Dog. Jack never forgot it, and more than once it saved his life. In color as well as in power he was a rarity. Animals are colored in one or other of two general plans: one that matches them with their surroundings and helps them to hide--this is called "protective"; the other that makes them very visible for several purposes--this is called "directive." Jack-rabbits are peculiar in being painted both ways. As they squat in their form in the gray brush or clods, they are soft gray on their ears, head, back, and sides; they match the ground and cannot be seen until close at hand--they are protectively colored. But the moment it is clear to the Jack that the approaching foe will find him, he jumps up and dashes away. He throws off all disguise now, the gray seems to disappear; he makes a lightning change, and his ears show snowy white with black tips, the legs are white, his tail is a black spot in a blaze of white. He is a black-and-white Rabbit now. His coloring is all directive. How is it done? Very simply. The front side of the ear is gray, the back, black and white. The black tail with its white halo, and the legs, are tucked below. He is sitting on them. The gray mantle is pulled down and enlarged as he sits, but when he jumps up it shrinks somewhat, all his black-and-white marks are now shown, and just as his colors formerly whispered, "I am a clod," they now shout aloud, "I am a Jack-rabbit."
