The exact nature and relation of the various dances are very little known among most of the tribes of the Central region. Probably a typical example of these dances is furnished by the Maidu of the Sacramento valley, who declare that their ceremonies were obtained from their neighbors, the Wintun. This statement is borne out by indirect evidence. Among the Maidu the ceremonies were performed in winter and constituted a series of fifteen or more distinct dances, coming for the most part in a definite order. So far as known they were the following: Hesi, Luyi, Loli, Salalu-ngkasi, Duck, Bear, Coyote, Creeper, Turtle, Aloli-ngkasi, Yokola-ngkasi, Moloko-ngkasi, Deer, Aki, Hesi. The majority of these dances were performed by men, but some by women only. There is no evidence that participation in these dances was dependent upon anything like membership in an association. Each had its characteristic paraphernalia or combinations of paraphernalia. In several there are participants with special apparel and with a distinctive name. At least some of these seem to represent mythical characters. In several instances these performers enact ceremonial operations, largely in the nature of complex approaches and departures which take place outside the assembly chamber. The names of several of these ceremonies occur also among neighboring Indians speaking entirely different languages, and thus give proof of the transmission of the ceremonies from one locality to another. The Hesi, the most important of the Maidu series, is danced also by the Wintun. The Loli is an important ceremony among the Maidu, Miwok, and Pomo. The performer called Kuksu, who refers to important myths, is found among the Maidu, Wintun, Pomo, and either the Miwok or Costanoan Indians formerly at Mission San José. There is every reason to believe that a fuller acquaintance with the tribes whose ceremonies are as yet least known will reveal other instances of ceremonies held in common and known under the same name. Farther to the south, among the Yokuts of the Tulare basin, these ceremonies do not seem to have penetrated. Here the majority of the public ceremonies, like the rattlesnake ceremony that has been mentioned, were of the nature of shamanistic performances. Throughout the Central region the dances, while they might be held only in structures of certain kinds, were never rigorously attached to a specific locality.
