e 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.

On this basis we have six villages with a total of 140 houses and an
average of nearly 23. This would mean an aboriginal population of 1,610
persons. If we were to admit no declining population in 1870 but if we
allowed that Unutsawaholma, with 17 houses, was of average size in
aboriginal times, the value would still be 1,010 for the population of
Alexander Valley.

Driver states, in conjunction with his village list, "these certainly
not all inhabited at the same time." His opinion may be justified but
he cites no evidence in its support, and the circumstantial data
brought out with respect to each village separately does not indicate
that discontinuance of habitation occurred very long ago. It is true
that Alexander Valley was the scene of a minor intertribal war in the
early years of the nineteenth century, as the result of which the Pomo
were driven out by the Wappo. In the confusion there may have been some
shifting of inhabitants and reconst
