The taboo is in existence in all its force among the Navahoes. The most singular of these is that which forbids a man ever to look upon the face of his mother-in-law. Among civilized people it is a standard subject for rude jesting, this relationship of the mother-in-law, but with the Navahoes, the white man's jest is a subject of great earnestness. Each believes that serious consequences will follow if they see each other; hence, as it is the custom for a man to live with his wife's people, constant dodging is required, and the cries of warning, given by one or another of the family to son or mother-in-law, are often heard. I was once photographing the family of Manuelito, the last great war-chief of the Navahoes. The widow of the chief, her two daughters, their husbands and children, made up the group. But there was no getting of them together. I would photograph the mother with her daughters and grandchildren, but as soon as I called for the daughters' husbands, the mother "slid" out of sight, and when I wished for her return, the men disappeared. Then, too, a Navaho will never touch fish, much less eat it. According to one of the shamans, the reason for this is, that some of their ancestors were once turned into fish in the San Juan River, and, were they to eat fish, they might thus become cannibals, and eat descendants of their own ancestors. As neither Matthews nor Stephen refers to this cause of the taboo, I merely give it for what it may be worth. The former tells of a white woman, who, in a spirit of mischief, threw a pan of water in which fish had been soaked over a young Navaho. He changed his clothes and bathed himself carefully, in order that no taint of the tabooed fish might remain upon him. I have had a great deal of fun by innocently offering candy in the form of fish to Navahoes. As they are fond of candy, it was a strong proof of the power of the taboo that they invariably refused to touch it. Superstition naturally forms a large part of the Navaho's thought. He believes in charms, amulets, fetishes, witchcraft, taboos, magic, and all the wondrous things he can conceive. His name for a personal fetish is _Bizha_, "his treasure, something he especially values; hence his charm, his amulet, his personal fetish, his magic weapon, something that one carries to mysteriously protect himself." The talisman or amulet for the gambler is a piece of fine turquoise, because Noholipi, a gambling god, who appears in their Origin Legend, was made successful always with a large piece of this precious stone. There are quite a number of medicine-men, or shamans, among the Navahoes, some good, others bad. It has been my privilege to know several who are men of dignity and character.
