We might use the Yurok family number 7.5, but Goddard's account carries the implication that perhaps the Wailaki family was somewhat smaller, suggesting a factor of 7.0 rather than 7.5. Goddard bases his estimates upon a mean population of 15 to 30 persons per village. This would mean 4.5 persons per house, certainly too low a value for the aboriginal social family. At four houses per village the family number would be 5.6, still probably somewhat too low. Perhaps a compromise is advisable, say at 6.0. The average village size could be then put at 25 persons, a figure definitely lower than was assumed for the more northerly Athapascan tribes but still one which seems to be indicated by the social organization described by Goddard. The total population of the Wailaki proper would then be 80 per cent of 482 houses multiplied by 6.0 or 2,315 persons. Goddard indicates on page 108 his belief that the villages were not simultaneously inhabited. However, he adduces no evidence to favor this view. On the contrary, he mentions in his text four villages which were stated by informants _not_ to have been inhabited within their memory, a circumstance which argues strongly that the villages they did claim were actually active at the time to which they were referring, i.e., just before the white invasion. It would appear to the writer that reducing the house count by 20 per cent and reducing the family number from 7.5 to 6.0 quite adequately compensates for any errors in the ennumeration of villages. Indeed the estimate here presented may be too conservative. With regard to the Pitch group Goddard (1924) shows that the subtribe tokya-kiyahan had 15 villages. In fourteen of these he found 66 house pits, an average of 4.72 per village. At tciancot-kiyahan there were 16 villages, 7 of which had 35 house pits, or an average of 5.0. Todannan-kiyahan had 6 villages but the area was incompletely examined and there were probably more. The area of tcocat-kiyahan was not seen at all but there is certainly no reason why they should not have had at least 6 villages. At four houses per village the total, surely an underestimate, would be 172 and at 6.0 persons per house the population would be 1,032. For the entire Wailaki the indicated population is then 3,347 (or rather 3,350), a figure much in excess of previous estimates but justified by the data presented by Goddard and Merriam. _Wailaki ... 3,350_ _ATHAPASCAN TOTAL ... 15,450_ THE YUKI THE COAST YUKI The Coast Yuki have been the subject of an admirable ethnographic study by Gifford (1939), who has assembled substantially all the data extant in modern times pertaining to families and villages. He shows very clearly that this tribe occupied its villages only in a transitory manner, that it had summer beach camps and inland winter settlements. To quote Gifford's words concerning the point (p. 296):
