In treating the various tribes it has been deemed advisable that a geographic rather than an ethnologic grouping be presented, but without losing sight of tribal relationships, however remote the cognate tribes may be one from another. To simplify the study and to afford ready reference to the salient points respecting the several tribes, a summary of the information pertaining to each is given in the appendices.
In the spelling of the native terms throughout the text, as well as in the brief vocabularies appended to each volume, the simplest form possible, consistent with approximate accuracy, has been adopted. No attempt has been made to differentiate sounds so much alike that the average student fails to discern the distinction, for the words, where recorded, are designed for the general reader rather than the philologist, and it has been the endeavor to encourage their pronunciation rather than to make them repellent by inverted and other arbitrary characters.
I take this opportunity to express my deep appreciation to those who have so generously lent encouragement during these years of my labor, from the humblest dwellers in frontier cabins to the captains of industry in our great commercial centres, and from the representatives of the most modest institutions of learning to those whose fame is worldwide. Without this encouragement the work could not have been accomplished. When the last opportunity for study of the living tribes shall have passed with the Indians themselves, and the day cannot be far off, my generous friends may then feel that they have aided in a work the results of which, let it be hoped, will grow more valuable as time goes on.
