8, 9, and 10. _Lower Lake._ The three groups inhabiting the entire region of the southeast were the Kamdot, Elem, and Koi. Each had a principal village plus from two to four others with assembly houses. They are in the same terrain with and appear to be quite similar to Cigom. Palmer gives for the three a total population of 390, which, if increased by 50 per cent, would mean 585. If, on the other hand, we regard them as being of the same character as Cigom we could multiply 235 by 3 and get 705. A curious contributory bit of evidence can be derived from Gifford's study of land ownership in this area (1923). Gifford shows that the ownership of property at Cigom was communal but at Kamdot, Elem, and Koi, it was a family matter. He lists very carefully the exact ownership of the tribal real estate. There were 22 tracts belonging to the _village_ of Cigom but 85 belonging to _families_ of Elem, 38 to _families_ of Koi, and 57 to _families_ of Kamdot. From this we can derive the minimum number of families for these places, for the tracts were simultaneously owned by different families. Using a factor of 6 persons per family the population of Elem would be 510. In this connection it is of interest that Gifford during the same investigation found that two subsidiary villages were occupied simultaneously with the main village. Thus he states (p. 86): "A second mainland overflow village, which was once _contemporaneously inhabited_ with insular Elem and mainland Behepkobel, was Mucokol...." (Emphasis mine.) A principal village the size of Cigom or larger plus two accessory villages of only 100 each would bring the population to 435. Thus there can be little doubt that Elem had fully 500 inhabitants. On the basis of family number the figures for Koi and Kamdot would be respectively 228 and 342, or, say, 230 and 340. According to the data above the total population of the Clear Lake basin was 3,155, which may be rounded off to 3,150. When Kroeber originally formulated an estimate of the population of the Pomo communities, based largely upon Barrett's study, he set the average per community at 100. Later (Gifford and Kroeber, 1937, p. 119) he reduced the probable number of communities and reset the population limits at 75-300. with a likely average of 200. The average we get here is 287, considerably larger than Kroeber would allow. However, all the available evidence seems to support the conclusion that, for the Clear Lake region at least, the community size was somewhat larger than stated by Kroeber.
