'The Mattoles have their habitat on the creek which bears their name, and on the still smaller stream dignified with the appellation of Bear River. From the coast they range across to Eel River, and by immemorial Indian usage and prescriptive right, they hold the western bank of this river from about Eagle Prairie, where they border upon the Veeards, up southward to the mouth of South Fork.' Powers' Pomo, MS.

RUSSIAN RIVER AND COAST TRIBES.
The Pomos consist of 'a great number of tribes or little bands, sometimes one in a valley, sometimes three or four, clustered in the region where the headwaters of Eel and Russian rivers interlace, along the estuaries of the coast and around Clear Lake. Really, the Indians all along Russian river to its mouth are branches of this great family, but below Calpello they no longer call themselves Pomos.... The broadest and most obvious division of this large family is, into Eel river Pomos and Russian river Pomos.' Powers, in Overland Monthly, vol. ix., pp. 498-9.
