Indirect confirmation of this conclusion comes from comparison of the Huchnom village distribution with that of the subtribes of the Yuki proper. The Tanom had 6 nohots scattered along approximately 20 miles of the Eel River and the Witukomnom had 4 or 5 along some 15 miles of stream valley. The Huchnom territory was about 270 square miles and, judging roughly from the maps of Foster and Barrett, the Tanom and the Witukomnom areas were approximately 200 square miles each. The Tanom possessed at least 6 nohots and the Witukomnom 9 (Foster's data). Hence the average area covered per nohot would be 33 for the Tanom and 22 for the Witukomnom. If we allow 11 primary villages or nohots for the Huchnom the average area covered by each would be 25, entirely within the same range. Now the character of the terrain for the three groups did not differ in any essential respect. Hence there is no reason to suppose that the population density of the Huchnom, computed on a riparian or area basis, was any less than that of the other two subtribes. Furthermore I can see no evidence pointing to a smaller individual community or village population among the Huchnom. Eleven nohots or village constellations would yield a total population of 2,090, or approximately 2,100, an estimate somewhat smaller than the one given previously but one which I can find no reason for further reducing. Some confirmation of the figure derived from village data is contained in the survey of Heintzelman (1855). He mentions as one of his principal divisions the Bi-lo-ki, a name which is the same as Balokai. The latter were the Pomo of Potter Valley, according to Kroeber and also Barrett (p. 128). This group, Heintzelman says, included 3,000 persons. However, he breaks them down into six smaller divisions and says that "these Indians reside between Clear Lake and the heads of Eel, Russian and Trinity Rivers." The six divisions are: 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 undoubtedly Potter valley Pomo. The Si-mas, according to a personal communication received from Dr. Barrett, are probably Yuki from the region of the headwaters of the South Eel River (the tcimaia mentioned in the Ethnogeography of the Pomo, 1908. p. 247). The Di-no-kis and the Du-che-calla-os Dr. Barrett is unable to identify. The Tar-toos are undoubtedly Huchnom (see Barrett's monograph, 1908. p. 256; also confirmed by personal communication). Their number is given by Heintzelman as 1,600. This value, for 1855, bespeaks an aboriginal population not far from 2,000. Hence again the ethnographic method is supported by the estimate of the contemporary observer. _Huchnom ... 2,100_ _YUKI TOTAL ... 9,730_ THE ATHAPASCANS AND THE YUKI
