This little trick is probably very widely distributed; it has been observed among the Omahas, the Pawnees and the Kwakiutls; the Japanese, and the Caroline Islanders. Dr. Boas informs Dr. Haddon (see American Anthropologist, v, 1903, p. 218) that there are two shamanistic societies among the Kwakiutls, and that this trick is used to identify the members of one of these societies when they meet in the forest. The members of the other society are recognized by another trick, which, since it requires the use of a stick, does not fall within our subject. The trick has also been described from Argyleshire by Dr. R. C. Maclagan (p. 189) as the "thumb loop."
