William H. Hinson tells us why animal trainers carry a stool when they go into a cage of lions. They have their whips, of course, and their pistols are at their sides. But invariably they also carry a stool. Hinson says it is the most important tool of the trainer. He holds the stool by the back and thrusts the legs toward the face of the wild animal. Those who know maintain that the animal tries to focus on all four legs at once. In the attempt to focus on all four, a kind of paralysis overwhelms the animal, and it becomes tame, weak, and disabled because its attention is fragmented.
