8. _So-as._ Barrett considers (personal communication) that this name refers to the village of _sosa-tca_, in Sherwood Valley (cf. 1908, p. 147). Irrespective of conflicts in terminology it appears that Heintzelman fairly well covered the area usually assigned to the Northern Pomo under the eight designations just listed. His total population value is 5,350, slightly greater than but very close to the estimate derived from ethnographic data (i.e., 5,040). This close correspondence will be seen as specially significant when we come to examine his report on the Central and Southern Pomo. _Northern Pomo ... 5,040_ CENTRAL POMO _Ukiah._--In the Ukiah area are included four of Stewart's subtribes: the Yokaia of Ukiah Valley, the Ciego of Largo, the Cokoa of Hopland, and the Yobakeya of Echo. There are all consolidated by Merriam in his manuscript entitled "Tribe List of Yo-ki-ah Pomo" and will be considered together. Stewart is very positive that these four tribes all lived in one central village. He says regarding the Yokaia: "Although several villages are given by Barrett for this area, there is no doubt that during the winter months the population was concentrated in one main village" (p. 43). Regarding the Cokoa: "Politically, as well as geographically, the Cokoa resembled the Yokaia. Both had a single central village of importance where the population was concentrated" (p. 43). Merriam credits Barrett with 37 village names, to which he adds none himself. Of the 37 he confirms only 13. Since the other 24 of Barrett are doubtful, they may be excluded. Of Merriam's 13 Stewart says specifically that three were camps not permanent villages. Two, Kah-chi-o (Katcayo) and Shah-na-na-oo (Caneneu) were proved by Stewart to have existed only subsequent to the white invasion. One may belong to the Booneville tribe and another is a tribal, not a village, name. Four, Kah-ka-eu (Cokadjal). Ko-lo-ko (Koloko), Lema (Ciego), and Shanel (Canel) were the main villages, as stated by Stewart. There remain unaccounted for only Bok-shah (Barrett's Bokca), regarding which Merriam says it had a sweathouse and was "practically permanent," and Katch-a-wah-low. Merriam's conclusions thus coincide to a remarkable degree with those of Stewart and justify the assumption that, where the two investigators clearly differ, considerable weight should be given to Merriam's account. The largest of the four main villages was Canel, or Shanel. Comment has already been made upon the fact that both Stephen Powers' and Stewart's informants, proceding from entirely different premises, reached the conclusion that the town had a primitive population of 1,500. This figure therefore, however incredible, must be accepted. It is noteworthy in passing that if we apply the family number of 14 to the 104 houses shown by Powers on his map of the town, the population is computed at 1,456, almost identical with the other estimates.
