Dick Rock was a stalwart ranchman in the prime of life, who possessed a great fondness for big-game animals. He lived not far from the western boundry of the Yellowstone Park. He liked to rope elk and moose in winter, and haul them on sleds to his ranch; to catch mountain goats or mule deer for exhibition; and to breed buffaloes. His finest bull buffalo, named Indian, was one of his favorites, and was broken _to ride!_ Scores of times Rock rode him around the corral, barebacked and without bridle or halter. Rock felt that he could confidently trust the animal, and he never dreamed of guarding himself against a possible evil day. But one day the blood lust seized the buffalo, and he decided to assassinate his best friend. The next time Dick Rock entered the corral, closing the gate and fastening it securely,--thus shutting himself in,--the big bull attacked him so suddenly and fiercely that there was not a moment for either escape or rescue. We can easily estimate the suddenness of the attack by the fact that alert and active Dick Rock had not time even to climb upon the fence of the corral, whereby his life would have been saved. With a mighty upward thrust, the treacherous bull drove one of his horns deeply into his master's body, and impaled him so completely and so securely that the man hung there and died there! As a crowning horror, the bull was unable to dislodge his victim, and the body of the ranchman was carried about the corral on the horns of his assassin until the horrified wife went a mile and a half and summoned a neighbor, who brought a rifle and executed the murderer on the spot. Such sudden onslaughts as this make it unsafe to trust implicitly, and without recourse, to the good temper of any animal having dangerous horns. If bird-lovers knew the prevalence of the murder instinct among the feathered folk, no doubt they would be greatly shocked. Many an innocent-looking bird is really a natural villain without opportunity to indulge in crime. It is in captivity that the wickedness inherent in wild creatures comes to the surface and becomes visible. In the open, the weak ones manage to avoid danger, and to escape when threatened; but, with twenty birds in one large cage, escape is not always possible. A "happy-family" of a dozen or twenty different species often harbors a criminal in its midst; and when the criminal cunningly waits until all possibilities of rescue are eliminated, an assassination is the result.
