Previous to the year 1906 the researches of the Bureau were restricted to the American Indians, but by act of Congress approved June 30 of that year the scope of its operations was extended to include the natives of the Hawaiian islands. Funds were not specifically provided, however, for prosecuting investigations among these people, and in the absence of an appropriation for this purpose it was considered inadvisable to restrict the systematic investigations among the Indian tribes in order that the new field might be entered. Fortunately the publication of valuable data pertaining to Hawaii is already provided for, and the present memoir by Doctor Emerson is the first of the Bureau's Hawaiian series. It is expected that this Bulletin will be followed shortly by one comprising an extended list of works relating to Hawaii, compiled by Prof. H. M. Ballou and Dr. Cyrus Thomas.
