When we examined Gifford's figures for the Clear Lake Pomo village of Cigom we found 5.0 persons per family, 2.35 families per house, and 11.75 persons per house. The similarity between the two sets of values, derived by different investigators independently, is clearly significant. Moreover, the slightly smaller numbers discovered by Driver at Unutsawaholma are explicable on the basis of the later date (1870) taken as the base line. At any rate there can be no doubt that the two villages were remarkably alike in composition of population. In computing aboriginal population at Cigom and the surrounding country it was pointed out that Gifford actually was dealing with a _declining_ population and that, if the aboriginal state were to be conceived properly, his figures would have to be increased. For this reason the family number was set at 7 instead of 5, which raised the number of persons per house to 16.45. Because of other evidence the latter value was reduced to 14.0. For Driver's village the same considerations must apply. However, since the family number was found to be 4.38, rather than 5.0 the aboriginal value may be put at 6 instead of 7. Then, if the number of families per house is 1.91, the average persons per house would be 11.5, a figure which there is no strong reason for changing. It now appears that, if Unutsawaholma "formerly" had 17 houses, with 11.5 persons per house, the "former" population would have been approximately 195, or in round numbers 200. Returning the matter of houses, Driver says (p. 184) that his informants "estimated" the number, but he thought the estimates were too high. (The number for the village of Unutsawaholma was evidently known exactly.) I think we have to concede Driver's point but we still do not know how great was the exaggeration. We note that Unutsawaholma with 17 sure houses "formerly" had 1 sweathouse but no designation "large" or "small." Of the two "large towns" one had 2 sweathouses and the other had 1 sweathouse and 40 ordinary houses. The same numbers were assigned to two other villages but they were not called large or small. The one called "small" had 1 sweathouse. The village, therefore, with 1 sweathouse and 17 other houses, but not designated either large or small, may be taken as approximately intermediate. The small town may be assigned half this number, or 8 houses. Those with 40 estimated houses, but not called large, may be assigned 25 houses each. Netstul, a "large town" with 40 houses and 1 sweathouse, may be given 30 houses, and Koticomota, a "large town" with 2 sweathouses, may be given 35 houses. This is a purely arbitrary arrangement but it must come somewhere near fitting the facts.
