FOREWORD HE observations recorded in this memoir are based on a note- worthy collection of jade objects ‘gathered by Lieutenant Emmons during many years of study among the tribes of British Columbia and Alaska, together with a few specimens belonging to other collections. The articles of jade assembled by Lieutenant Emmons, which he has deposited for exhibition in the Museum of the American Indian, Heye Foundation, are of importance not only by reason of the wide range of finished implements and ornaments which they include, but also because of the number of worked bowlders and fragments that exhibit the processes of cutting and shaping. On this account the author has had exceptional facilities for conducting the study whose results this Museum now has the privilege of making available to students. GrorGcE G. HEYE, Director.
