times'." It is hardly to be expected that an old man could
very accurately transmit population data secured as a small boy at his
grandfather's knee. For these reasons I think Merriam's village names
cannot be discarded, unless specific evidence proves that they are
errors. They must be accepted as villages which at one time were
inhabited. There remains of course the possible contingency that some
of these places had been abandoned before the advent of the first white
influence or that they were spots inhabited for a short time during the
upheaval accompanying the American invasion. Since there is no
conceivable way in which we may ascertain the true facts in detail,
perhaps some arbitrary correction is desirable. Consequently the
following procedure is suggested: estimate the population on the basis
of all the Merriam names, then reduce by one-third. Such a method
should take care of all instances of temporary villages, camp sites
etc.

Applying the above principles, we may assign 150 inhabitants to
Boo-tah-kah-chut-te ("big roundhouse"), 50 to Che-ah-po-y-chut-te
("fair-sized but no roundhouse"), and 200 to She-ko-ki-chut-te ("two
big rancherias and roundhouse"). Two houses, or say 30 persons, may be
allocated to the other 10 sites of Merriam. The total would then be
700, which, reduced by one-third, gives as a final value 470.

For the Mato-pomo as a whole the population figure is 1,250. It is
difficult to see how a much lower figure could be set for the area.

For the Northern Pomo collectively there has been derived a population
estimate of 5,040. It is of interest to compare this figure with the
values cited by Heintzelman.

This officer listed eight names which can be indentified as falling
within the group being discussed. They are as follows.

1. _Si-dam._ This is _sedam_ of Barrett (1908, p. 141) and of
Stewart (1943, p. 41), located in Potter Valley.

2. _Po-ma Pomes._ This is _pomo_ of Barrett and Stewart, likewise
in Potter Valley.

3. _Kal-il-na-pomas._ This group was located between Martoo
(Sherwood) and Metumki (Little Lake) valleys and is possibly
equivalent to kalal-nokca, a village below Ukiah (Barrett, personal
communication). However the habitat specified by Heintzelman does
not support Barrett's surmise. The group undoubtedly lived much to
the north of Ukiah.

4. _She-bal-na-pomas._ These were in Sherwood Valley and are
referred to by Barr
