The author informs us in the preface that the aim of this book was to depict the life and ethnology of the Indian tribes on Puget Sound with as much detail as possible to preserve them, such as they were when the first whites stepped into their lands. This book is based on the collective materials of different pioneers into the unresearched territories. It tells about the history, routines, traditions, rituals, and beliefs of the Siwash tribe.
