People learn from other people, and races have forever learned from other races. Herein we are treated to an in-depth understanding of categorized social characteristics of the Native American peoples, primarily those of the western U.S. as they existed at the time of book publication (1908). 'In dealing with [the Native Americans] as a race, a people, therefore, I do as I would with my own race, I take what to me seem to be racial characteristics, or in other words, the things that are manifested in the lives of the best men and women, and which seem to represent their habitual aims, ambitions, and desires.' - Summary by Roger Melin & book foreword
