I am also indebted to Mr. Albert S. Gatschet and Mr. J. Owen Dorsey for
the preparation of many comparative lists necessary to my work.

The task of preparing the map accompanying this paper was greatly
facilitated by the previously published map of Gallatin. I am especially
indebted to Col. Garrick Mallery for work done in the early part of its
preparation in this form. I have also received assistance from Messrs.
Gatschet, Dorsey, Mooney and Curtin. The final form which it has taken
is largely due to the labors of Mr. Henshaw, who has gathered many
important facts relating to the habitat of North American tribes while
preparing a synonymy of tribal names.
