Beginning with what may be admitted as possible, we find that the Dene Hareskins practise a form of healing under hypnotic or mesmeric treatment. {38} The physician (who is to be pitied) begins by a three days' fast. Then a 'magic lodge,' afterwards to be described, is built for him in the forest. Here he falls into the Sleep of the Shadow; the patient is then brought before him. In the lodge, the patient confesses his sins to his doctor, and when that ghostly friend has heard all, he sings and plays the tambour, invoking the spirit to descend on the sick man. The singing of barbarous songs was part of classical spiritualism; the Norse witch, in The Saga of Eric the Red, insisted on the song of Warlocks being chanted, which secured the attendance of 'many powerful spirits'; and modern spiritualists enliven their dark and dismal programme by songs. Presently the Hareskin physician blows on the patient, and bids the malady quit him. He also makes 'passes' over the invalid till he produces trance; the spirit is supposed to assist. Then the spirit extracts the _sin_ which caused the suffering, and the illness is cured, after the patient has been awakened by a loud cry. In all this affair of confession one is inclined to surmise a mixture of Catholic practice, imitated from the missionaries. It is also not, perhaps, impossible that hypnotic treatment may occasionally have been of some real service. Turning to British Guiana, where, as elsewhere, hysterical and epileptic people make the best mediums, or 'Peay-men,' we are fortunate in finding an educated observer who submitted to be peaied. Mr. Im Thurn, in the interests of science, endured a savage form of cure for headache. The remedy was much worse than the disease. In a hammock in the dark, attended by a peay-man armed with several bunches of green boughs, Mr. Im Thurn lay, under a vow not to touch whatever might touch him. The peay-men kept howling questions to the kenaimas, or spirits, who answered. 'It was a clever piece of ventriloquism and acting.'
