Franz Boas,
The mind of primitive man
(1911)
“ In the composition of our people, the indigenous element has never played an important rôle, except for very short periods. In regions where the settlement progressed 253for a long time entirely by the immigration of unmarried males of the white race, families of mixed blood have been of some importance during the period of gradual development, but they have never become sufficiently numerous in any populous part of the United States to be considered as an important element in our population. ”
