The Religion of the Luiseño Indians of Southern California, by Constance Goddard DuBois, , at sacred-texts.com
The Tamyush, sacred stone bowls, were never made. They were among the first people, born of the Earth-mother. If the chief in whose charge they are, does not take good care of them they go away.
They have been seen going along the road, and one can follow their track in the dust. It is like a rattlesnake track, but broader.
At Pichanga one lately came there. A raven was seen flying along above the road, and every now and then he swooped down as if following some object. A man went to see what was there, and found the Tamyush. It had been coming along the road to Pichanga. He took it to his home and they had a big ceremony over it. The man is dead now.
