“But the hunters with terrible guns came and killed them for their skins, killed them by hundreds of thousands, and in just a few years those great herds became only a memory. Thunderfoot, once Lord of the Prairies, was driven out of all his great kingdom, and the Bison, from being the most numerous of all large animals, is to-day reduced to just a few hundreds, and most of these are kept in parks by man. Barely in time did man make laws to protect Thunderfoot. Without this protection he would not exist to-day. “A close neighbor of Thunderfoot's in the days when he was Lord of the Prairies was Fleetfoot the Antelope. Fleetfoot is about the size of a small Deer, and in his graceful appearance reminds one of Lightfoot, for he has the same trim body and long slim legs. He is built for speed and looks it. From just a glance at him you would know him for a runner just as surely as a look at Jumper the Hare would tell you that he must travel in great bounds. The truth is, Fleetfoot is the fastest runner among all my children in this country. Not one can keep up with him in a race. “Fleetfoot's coat is a light yellowish-brown on the back and white underneath. His forehead is brown and the sides of his face white. His throat and under side of his neck are white, crossed by two bands of brown. His hoofs, horns and eyes are black, and there is a black spot under each ear. Near the end of his nose he is also black, and down the back of his neck is a black line of stiff longer hairs. A large white patch surrounds his short tail. Who remembers what I told you about Antelope Jack, the big Jack Hare of the Southwest?” “I do!” cried Peter Rabbit and Jumper the Hare together. “What was it, Jumper?” asked Old Mother Nature. “You said that he has a way of making the white of his sides seem to grow so that he seems almost all white, and can signal his friends in this way,” replied Jumper. “Quite right,” replied Old Mother Nature. “I am glad to find that you remember so well. Fleetfoot does the same thing with this white patch around his tail. The hairs are quite long and he can make them spread out so that that white patch becomes much larger, and when he is running it can be seen flashing in the sun long after he is so far away that nothing else of him can be seen. His eyes are wonderfully keen, so by means of these white patches he and his friends can signal each other when they are far apart. “Fleetfoot has true horns, but they are unlike any other horns in that they are shed every year, just like the antlers of the Deer family. They grow straight up just over the eyes, are rather short, and fork. One branch is much shorter than the other, and the longer one is turned over at the end like a hook. From these horns he gets the name of Pronghorn.
