Medicine-men are often used as instruments for the working of private revenge. Cowards are to be found among Indians as among white men. Among white men these despicable wretches attack their foes through the columns of newspapers or in the pages of magazines, while among the former they call in the services of a medicine-man. This hired charlatan then either directly or by proxy works upon the fears of the man he is hired to injure. Sometimes he actually poisons or otherwise harms him under pretence of protecting him. But the Indian is dreadfully superstitious, and to work upon his mind is easy, and he soon imagines himself to be sick. For the cure of disease the better class of Navaho shamans have a system of chanting, praying, dancing, bathing, sweating, etc., that Dr. Matthews has fully described in the United States Bureau of Ethnology reports. The complexity of these ceremonies cannot be comprehended or conceived by those whose knowledge of the Indian is superficial and casual. If, however, a shaman makes himself unpopular, or fails to cure in several successive cases, or earns the enmity of a treacherous shaman foe, he is liable to be accused of witchcraft, and if a sufficient number of the people can be made to believe the charge he is speedily done away with. One of the shamans made famous by Dr. Matthews was recently killed on account of his harsh and tyrannical manner. He was accused of witchcraft and shot. Hence it will be seen that the Navaho is not yet perfect--any more than his white brother. No, indeed! There are other points in which he is similar to his brother of the white skin. Some years ago I journeyed in a wagon with an old Arizona pioneer, Franklin French, from Winslow, on the line of the Santa Fé, through the Hopi country, the Mormon town of Tuba City, past the Navaho settlements of Willow Springs, Echo Reef, etc., to Lee's Ferry of the Colorado River. Beyond Willow Springs we camped one night, and I went to a Navaho hogan to purchase corn and vegetables for ourselves, and feed for the horses. Everything was six prices too high, but the Navahoes knew I was in need of their articles and raised the prices accordingly. It is not only the white man that understands the principle of "cornering the market." We compromised, however, and, after a hearty supper and a chat around the camp-fire, I rolled myself up in my blankets ready to sleep until called for breakfast in the morning.
