4. _Waterman._ With the list on page 206 is also given a list of villages derived from a map executed by a man named Randall, a county surveyor, in 1866. Although no house counts are given, the list is useful for establishing the existence of certain towns in the year 1866. 5. _Merriam._ The village lists for the Yurok follow Waterman and Kroeber quite closely. However, Merriam was able to locate several inhabited places which had escaped the attention of the other two investigators. These villages have been added in table 2 (p. 92, herein) and a conservatively estimated house count assigned to them. In table 1 (pp. 85-91, herein) will be found a list of 78 villages, based primarily on Waterman's data. Under each village name are assembled such facts as I can find in the writings of Kroeber and Waterman bearing on the existence of the town. In the third column is placed my own evaluation of these facts in the form of a statement whether such existence should be regarded as certain, probable, or doubtful. The results have been then transferred to table 2 (p. 92, herein). In the first column of this second table is the arbitrary number assigned each town shown in table 1 (pp. 85-91, herein), the doubtful towns being omitted. In the second column is the source, where the letter "l" denotes that the house number is derived from Waterman's list on page 206, the letter "t" that the number was derived from Waterman's textual descriptions, and the letter "M" that the data were secured from Merriam's village lists. The letter "R" indicates that the town appeared on Randall's map of 1866 but was not adequately discussed by Waterman or Kroeber. The letter "p" indicates that the house number is my own estimate. The third column shows the house number itself. In addition are shown the corresponding house numbers as taken from Kroeber's informants ("modern memories") or from the census of 1852 as cited by Kroeber. The total number of houses is 412, which, at 7.5 persons per house, gives a population of 3,090. Some insight into the validity of the value thus obtained may be secured by cross checking the various sources for house number. As a basis for comparison the list in table 1 (pp. 85-91, herein) may be used, since it is constructed for the great majority of villages from Waterman's final estimate. There are 16 towns for which a number is given in Waterman's list (1920, p. 206) and for which a statement of house numbers derived directly from informants is to be found in his detailed descriptions. For these towns the list shows 88 houses and the text 101. Now, if the same ratio of house numbers (_i.e._, 88 to 101) is applied to the total population as derived from table 2 (p. 92, herein) the result is a population of 3,562 persons.
