[Footnote 1:  Even more important than these is the relative decrease of the successful strains of the population, briefly treated in Vol.  I, ch. 33.  This is the problem of eugenics, the choice and biologic breeding of capable men to be the citizens of the nation, and broadly understood, it includes both the negro and the immigrant problems.]

[Footnote 6:  The latest and best statement is that of H.P.  Fairchild, “Immigration,” pp. 215-225, citing various opinions, and accepting the view of Walker.  But he says (p. 216):  “It must be admitted that this is not a proposition which can be demonstrated in an absolutely mathematical way, which will leave no further ground for argument.”]

[Footnote 8:  The effect of the growth of cities is discussed in the “American Journal of Sociology,” Vol. 18, p. 342, in an article on “Walker’s Theory of Immigration,” by E.A.  Goldenweiser.]
