n (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

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" w
