Of these three classes of ceremonies the mourning ceremonies are at least as important as the others and by far the most distinctive of the state as an ethnographic province, although neither they nor the secret society are found in the specialized Northwestern area. The mourning ceremonies further do not occur among the Athabascan, Yuki, and Pomo tribes to the south of the Northwestern tribes as far as the bay of San Francisco; but outside of this strip in the northern coast region they are universal in the state. Among the Maidu they are usually known as "burning," among the Miwok as "cry." Among the Yokuts they have been called "dance of the dead," and among the Mohave and Yuma "annual." These ceremonies are usually participated in by a number of visiting communities or villages. They last for one or more nights, during which crying and wailing, sometimes accompanied by singing and exhortation, are indulged in, and find their climax in a great destruction of property. While those who have recently lost relatives naturally take a prominent part, the ceremony as a whole is not a personal but a tribal one. Among the Yokuts and probably other groups it is immediately followed by a dance of a festive nature, and usually there is a definitely expressed idea that this general ceremony puts an end to all individual mourning among the participants. A typical form of the mourning ceremony is found among the Maidu, who call it östu. Each village or political unit possesses its burning ground. Participation in the ceremony is effected by receipt of a membership-string or necklace, both the receipt and return of which are marked by payments or presents. The ceremony is held in autumn in a circular brush enclosure. Property to be destroyed is tied to poles which are erected on the ground. After an opening exhortation by the chief or shaman in charge of the ceremony, the wailing begins, to continue throughout the night, many exclamations to the dead being uttered. Toward morning the numerous articles displayed on the poles are taken down and burned. When everything has been destroyed the assembly breaks up for gambling and feasting. The purpose of the ceremony is to supply the ghosts of the dead with clothing, property, and food. Although its general tenor is communal, each family offers only to its own relatives. In some cases elaborate images of stuffed skins ornamented with dancing apparel are made to represent important people who have died. These are burned with the property offered to the dead.
