evoked wildness—a man coming into the stall with a saddle or attempting to put a bridle over the horse’s head—are increased until the animal not only shows no wildness or aversion, but may even approach its trainer. This is a procedure requiring considerable judgment.

In the second method discussed by Guthrie, that of fatigue, the horse is confronted by the feared stimuli all at once, the confrontation continuing regardless of the animal’s wild behavior until, worn out, it can respond wildly no more and becomes habituated to the aversive stimulation. This is the “bronco busting” technique, and it requires a very able and tough animal therapist indeed. The analogues to this procedure in human psychotherapy are milieu therapy, psychodrama, and group therapy, where violent emotional outbursts to the point of fatigue permit habituation to the stimuli that previously evoked these responses.

John Rarey discovered a shortcut. From his own experience, punctuated by nips and broken bones, he learned to immobilize horses quickly and then hypnotize them. Once immobilized and thus unable to run, buck, kick, crowd, or bite—unable to be wild or vicious—the horses were flooded with the sight and sound and smell and touch of man, the very stimuli that formerly drove them to wildness. Once they were habituated to these stimuli, their wildness ceased. For some horses, man was simply no longer strange; others learned, despite their prior experience, that man was not a source of pain.

The state of immobility wherein stimuli may be received but not acted on is variously known as death-feigning, tonic immobility, cataplexy, catalepsy, paroxysmal inhibition, recumbency reflex, or, more generally, animal hypnosis. Svorad in Czechoslovakia has studied the brain waves of many hypnotized animals and notes that stimuli do register but that the responses to them are inhibited. In the United States, Nina Bull dealt with the same sort of “blocking” in her hypnosis studies of human emotions.

Rarey’s procedures for hypnotic induction in horses are the same as those used with dogs or cats or other animals. Stroking of the belly or steady pressure against the animal’s side, or holding the snout down while blowing steadily in the ear are all commonly practiced, but all require the animal to hold still. This is not a very serious matter with a dog or a cat, but a vicious horse can kill a man before he can even start the process of hypnosis. Rarey solved this inconvenience by use of the “Rarey strap” to hold the horse still so that induction could be started. Use of the strap is not of itself a trance-inducing technique, and it is not at all clear that Rarey recognized the importance of the hypnotic trance. This is probably the reason that references to him in the horse-handling literature of the late nineteenth and early twentieth century concentrate on the Rarey strap and speak of its usefulness in subduing vicious animals.

Rarey was quite a man. Even discounting his vibrant egoism

and an enthusiastic press, his feats of taming and tranquillizing were impressive indeed. Though he practiced his art a century ago, his techniques have the quality of having anticipated the scientific studies in hypnotherapy and desensitization theory of our own time.
