desire to perform the ceremony at least once a year in each of the larger villages. In Southern California mourning ceremonies are everywhere the most prominent. In the coast region, among the various groups of Mission Indians, initiation ceremonies make up most of the public rituals that are not connected with mourning. In the interior the Mohave possess no initiation ceremonies. In both regions such ceremonies as partake neither of the nature of mourning nor initiation are conspicuous by the prominence of the myth element. They consist essentially of long series of songs, occupying one or more nights in the recital, which recount, in part directly but more often by allusion, an important myth. At times the myth is actually related in the intervals between the songs. In some cases dancing by men or women accompanies the singing, but this is never spectacular and in many cases is entirely lacking. Being only ceremonial recitations of myths, these ceremonies are not attached in their performance to specific localities, and when dancing regalia are used they are of the simplest character; nor is there opportunity for either altar or ritual. The predominance of the mourning element in the ceremonies of this region is further shown by the fact that among some tribes, as the Mohave, these same singing ceremonies, besides being performed independently, are also sung for many hours at every death. The series of songs selected for each individual on this occasion is that with which he is acquainted. In accord with what has been said of the dream as the basis of Mohave religious life, these singing ceremonies are almost always believed by each person to have been dreamed by himself. CEREMONIAL STRUCTURES AND PARAPHERNALIA. The ceremonial chamber is also of distinctive character in the three culture areas. In the Central region it is a large, circular, dome-shaped structure, partly underground and with a covering of earth. It serves also as place of assembly and at least at times as sudatory, whence its popular name of sweat-house. In the Northwest the sweat-house is quite small, almost entirely underground, and its roof consists of boards without a covering of earth. It is constantly used for sweating and is the regular sleeping place of all adult males. It is not used for public ceremonies except in the case of the dance initiating shamans. In the South the ceremonial structure is not a house, but either a mere enclosure of brush, as among the Mission tribes, or a simple shade of brush on upright posts, as among the Mohave. This type of ceremonial structure is also found in the southern part of the Central region among the Yokuts.
