Mr. GERARD FOWKE, in addition to assisting in the preparation of the final report on the field work of the mound exploration division, has made a study of the stone articles of the collection made by it. Mr. H. L. REYNOLDS has made a study of the copper articles collected, and has prepared a paper which is nearly completed. Mr. J. D. MIDDLETON’S office work has consisted entirely in the preparation of maps, charts, and diagrams. These are of two classes-- (1) those made entirely from original surveys, which constitute the larger portion, and (2) the archeological maps of States and districts, showing the distribution of given types, which are made from all the data obtainable, including additions and verifications made by the mound exploration division of the Bureau. Mr. J. C. PILLING continued his bibliographic studies during the year, with the intention of completing for the press his bibliography of North American languages. After consultation with the Director and a number of gentlemen well informed on the subject, it was concluded that the wants of students in this branch of ethnology would be better subserved if the material were issued in separate bibliographies, each devoted to one of the great linguistic stocks of North America. The first one selected for issue related to the Eskimo, which was prepared during the year, and when put in type formed a pamphlet of 116 pages. The experiment proved successful, and Mr. Pilling continued the preparation of the separates. Late in the fiscal year the manuscript of his bibliography of the Siouan family was sent to the Public Printer. It is the intention to continue this work by preparing a bibliography of each of the linguistic groups as fast as opportunity will permit. Mr. FRANK H. CUSHING continued work upon his Zuñi material, so far as his health permitted, until the middle of December. At that time he gave up office work and left for Arizona and New Mexico, intending to devote himself for a time to the examination of the ruins of that region with the view of obtaining material of collateral interest in connection with his Zuñi studies as well as in hope of restoring his impaired health. Mr. CHARLES C. ROYCE, although no longer officially connected with the Bureau, devoted much time during the year to the completion of his work upon the former title of Indian tribes to lands within the United States and the methods by which their relinquishment had been procured. This work, delayed by Mr. Royce’s resignation from the Bureau force, is reported by him as nearly completed.
