The Indians had horses for all purposes. The buffalo horse was merely a trained cow pony; he bore a special mark or nick in his ear to distinguish him. He had to be alert, intelligent, willing to follow the game and press close to the side of the running animal, yet able to detect its intention and swerve from it so as not to become entangled, and all with no more guidance than the Indian exerted by pressure of his knees. The war horse and the buffalo horse were renowned for their speed, intelligence, and endurance. They were prize possessions and were valued above all else.
