stimulated investigation, giving wiser direction to inquiry, and the results have abundantly proved the value of the 'Instructions' and the wisdom of its publication; and it serves to mark an epoch in the history of ethnographic investigation in America. The material which has thus been accumulated is of great amount, and its study has led to such important conclusions that it is deemed wise to prepare a new system of instruction, more comprehensive in plan and more elaborate in detail. First, it is found necessary to enlarge the alphabet so as to include a greater number of sounds, which have been discovered in the North American languages, and to mark other letters with greater precision. Second, it is necessary to enlarge the vocabulary so as to modify it somewhat, as experience has dictated, so that new words may be collected. Third, it is desirable that many simple phrases and sentences should be given—so chosen as to bring out the more important characteristics of grammatic structure."

In the preparation of this paper, the alphabet was considered to be of prime importance. Concerning it, the author says: "After devoting much time to the consideration of the subject, and the examination of many alphabets devised by scholars and linguists, none was found against which there was not serious objections, and the author attempted to devise an alphabet which would contain all the supposed requirements; but there were many difficulties in the way, and many compromises to be made in weighing the various considerations. At this stage of the work he applied to the eminent philologist, Prof. W. D. Whitney, for assistance. After much consultation and the weighing of the many considerations arising from the large amount of manuscript material in the author's hands, Professor Whitney kindly prepared the following paper on the alphabet."

The words, phrases, and sentences to be collected are arranged in schedules, each preceded by instructions, and followed by blanks for additions, as follows:

This paper was prepared with special reference to the wants of the collector, being printed on bond paper and bound in flexible cloth. It was widely distributed and, like that of Mr. Gibbs, resulted in the collection of valuable linguistic material.

In 1879 Congress consolidated the various surveys, including that of the Rocky Mountain Region, into the United States Geological Survey, but made provision for continuing the publication of the Contributions to North American Ethnology under the direction of the Secretary of the Smithsonian Institution, and directed that the ethnologic material in Major Powell's hands be turned over to the Institution. Thus the Bureau of Ethnology of the Smithsonian Institution was organized, and Major Powell was placed at its head.

By this time the growing interest manifested in the study of North American linguistics rendered necessary the preparation of a new edition of the Introduction. In the words of the author:

"The progress made by various students, and the studies made by the author, alike require that a new edition be prepared to meet the more advanced wants and to embody the results of wider studies. Under these circumstances the present edition is published. It does not purport to be a philosophic treatment of the subject of language; it is not a comparative grammar of Indian tongues; it is simply a series of explanations of certain characteristics almost universally found by students of Indian languages—the explanations being of such a character as experience has shown would best meet the wants of persons practically at work in the field on languages with which they are unfamiliar. The book is a body of directions for collectors.

"It is believed that the system of schedules, followed seriatim, will lead the student in a proper way to the collection of linguistic materials; that the explanations given will assist him in overcoming the difficulties which he is sure to encounter; and that the materials when collected will constitute valuable contributions to philology. It has been the effort of the author to connect the study of language with the study of other branches of anthropology, for a language is best understood when the habits,
