 man at the Lindenmeier site in northern Colorado, bringing to light 

 more material evidence of this early American culture. Dr. Steward 

 continued his archeological and ethnological reconnaissance in west- 

 ern South America, in preparation for the editing of the proposed 

 Handbook of South American Indians, and completed preparations 

 for the actual beginning of this project. Mr. Collins, newly ap-

 Museum, worked over the large collection of prehistoric Eskimo 

 artifacts, several thousand in number, which he excavated on a 

 previous expedition to Cape Prince of Wales and other points in 

 the vicinity of Bering Strait. Dr. Fenton, appointed to the staff 

 of the Bureau in February 1939, wrote up the results of his previous 

 investigations among the Iroquois. Miss Densmore, a collaborator

 and Dance Songs" and "Choctaw and Seminole Songs." Mr. Carter, 

 another collaborator, worked with the ethnographic and Indian sign-

 Gen. Hugh L. Scott. The Bureau published its annual report and 

 six bulletins. 



International Exchanges. — The International Exchange Service 

 under the Smithsonian Institution acts as the official agency of the 

 United States for the interchange with other countries of govern- 

 mental and scientific documents. The number of packages of such 

 material passing through the Exchange Service during the year was 

 714,877, and the weight of these packages was 719,694 pounds. Ship- 

 ments to Spain were still suspended at the close of the year, but 

 efforts were being made through diplomatic channels to resume ex- 

 change relations. There are now being sent through the Exchange 

 Service to foreign countries 61 full sets of United States official 

 documents and 47 partial sets. One hundred and three copies of 

 the Congressional Kecord and the Federal Register are now sent 

 to foreign depositories. A very appreciative letter was received 

 from Dr. T. L. Yuan, officially connected with the Library Associa-

 publications presented by individuals and establishments throughout
