Ethnography of the Cahuilla Indians
by A. L. Kroeber
This is a short ethnography of the Cahuilla, who inhabited the desert of Southern California. This mostly covers material culture. However, Kroeber also includes some notes on place names, which solves the debate about where the city names Cucamonga, Yucaipa, Chino, and (notably) Azusa came from. (And no, it's not 'From A to Z in the USA.') --They are all Native American place names. We also learn that the original name of Los Angeles was Wenot.
In a short section on social and religious life, Kroeber notes that the 'large low-flying meteor' (Cahuilla dakush) is distinguished from ordinary shooting stars (ngamngam), which just deepens that mystery.
