The papers accompanying the Fourth Annual Report of this Bureau, which was for the fiscal year 1882-’83, included one under the title “Pictographs of the North American Indians, a Preliminary Paper, by Garrick Mallery.” Although that work was of considerable length and the result of much research and study, it was in fact as well as in title preliminary. The substance and general character of the information obtained at that time on the subject was published not only for the benefit of students already interested in it, but also to excite interest in that branch of study among active explorers in the field and, indeed, among all persons engaged in anthropologic researches. For the convenience of such workers as were invited in general terms to become collaborators, suggestions were offered for the examination, description, and study of the objects connected with this branch of investigation which might be noticed or discovered by them. The result of this preliminary publication has shown the wisdom of the plan adopted. Since the distribution of the Fourth Annual Report pictography in its various branches has become, far more than ever before, a prominent feature in the publications of learned societies, in the separate works of anthropologists, and in the notes of scientific explorers. The present paper includes, with proper credit to the authors quoted or cited, many contributions to this branch of study which obviously have been induced by the preliminary paper before mentioned. The interest thus excited has continued to be manifested by the publication of new information of importance, in diverse shapes and in many languages, some of which has been received too late for proper attention in this paper.
