If we total all the Yukian divisions, including the Coast Yuki and the Huchnom, we get 9,730 persons. Similarly, the Athapascan tribes collectively give 15,450. The combined total is 25,180. Some of the groups, such as the Tanom and Huchnom, may have been overestimated, but this will be compensated by underestimates for other groups, such as the Onkolukomnom. If we accept as valid the published ethnographic data of Barrett, Kroeber, Foster, and Gifford, together with the manuscript material of Merriam, it is very difficult to fix the population of the Athapascan and Yukian stocks at a figure much below 25,000. In this connection it is interesting to consider the estimates of Heintzelman, because his figures for the Kato and for the Huchnom have been shown to conform in general to those derived from village lists. Many of Heintzelman's Indian names cannot now be identified and his localities are frequently vague and obscure. However, a reasonably clear line can be drawn between the Pomo and those tribes living north of the Pomo. The first five groups mentioned in the report are unequivocally Pomo. Then come the "Bi-lo-ki, Po-mes" with the six divisions previously mentioned called Tar-toos, Si-dam, Po-ma Pomes, Si-mas, Di-no-kis, and Du-che-calla-os. The Si-dam and Po-ma Pomes are Potter Valley Pomo. The Tar-toos are Huchnom. The Si-mas are probably southeastern Yuki. The Di-no-kis and Du-che-calla-os cannot be identified by Dr. Barrett (personal communication) and are therefore probably not Pomo. Since the whole group was said by Heintzelman to reside "between Clear Lake and the heads of Eel, Russian and Trinity Rivers" these two unidentified divisions may be ascribed to the Yuki. The numerical aggregate of the four Yukian divisions is 2,450. Following the Bi-lo-ki on Heintzelman's list are the Me-che-pomas who inhabit the east part of Kinamoo Valley and the "Eel River Mountains," 40 miles northeast of the proposed site, i.e., Fort Bragg. Covelo is almost exactly 40 airline miles northeast of Fort Bragg. Barrett (1908, p. 249, fn.) says that the Pomo name for Round Valley is maca-kai, and quotes another variant, Me-sha-kai. In a personal communication he states his belief that Round Valley is here referred to. Along with the Me-che-pomas Heintzelman lists the Be-dar-ke-sill, which he says are found in the south part of Trinity County and the north part of Mendocino County, 50 miles from Fort Bragg. Since the name cannot be identified, the people may be allocated on the basis of location alone to the southern part of the Wailaki. The aggregate population of these two groups is given as 2,100.
