2. Tribes of California. Berkeley: University of California Press.

 This is a large nation, extending from the Sacramento to Honey Lake, and from Big Chico Creek to Bear River. Of separate tribes or villages there are many. I give what I could collect, first premising that the same name is applied to the locality and to the inhabitants of it, though this is not always the case (282).

 On Honcut Creek, going up, are the To-to and the Hel-to. In Concow Valley are the Kon-kau, once a large and powerful tribe, and probably the best representatives of this nation. All these tribes, in giving their full designation, add the word Maidu (282).
