This is the Indian story as told by the half-blood, who did not claim to have been an eye-witness, but spoke of it as a matter of common knowledge and beyond question. It is doubtless substantially correct. The hypnotic action described is the same which the author has repeatedly seen employed in the Ghost dance, resulting successively in involuntary trembling, violent spasmodic action, rigidity, and final deathlike unconsciousness. The Ghost dancers regard the process not only as a means of bringing them into trance communication with their departed friends, but also as a preventive and cure of disease, just as we have our faith healers and magnetic doctors. With the Indian’s implicit faith in the supernatural ability of the doctor, it is easy to suppose that the mental effect on the woman, who was told and believed that she was to be cured, would aid recovery if recovery was possible. It is unlikely that death resulted to the medicine-man. It is more probable that under the hypnotic spell of the doctors he fell unconscious and apparently lifeless and remained so perhaps for a considerable time, as frequently happens with sensitive subjects in the Ghost dance. The fact that the same process should produce exactly opposite effects in the two subjects is easily explainable. The object of the hypnotic performance was simply to bring the mind of the subject under the control of the operator. This accomplished, the mental, and ultimately the physical, effect on either subject was whatever the operator wished it to be. After bringing both under mental control in the manner described, he suggested recovery to the woman and sickness or death to the medicine-man, and the result followed. Until the advent of these women from beyond the mountains such hypnotic performances seem to have been unknown among the Yakima and other eastern tribes of the Columbia region, the trance condition in the Smohalla devotees being apparently due entirely to the effect of the rhythmic dances and songs acting on excited imaginations, without the aid of blowing or manual passes. Hypnotism and so-called magnetism, however, appear to have been employed by the medicine-men of the Chinook tribes of the lower Columbia from ancient times. Especially wonderful in this connection are the stories told of one of these men residing at Wushqûm or Wisham, near The Dalles.
