I have accepted Merriam's line here because he has more detailed information than Kroeber on the neighboring Whilkut.
Kroeber, Handbook, p. 278, inferentially concurs with this conclusion.
Kroeber thus defeats his own argument with respect to the small decline and protected position of the Karok and Hupa.
The first attempt at population estimates in detail and with the use of a variety of data was made by Kroeber .
On the basis of such distinctions Kroeber reduces the total count by a factor of one-sixth.
