6 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1941 



work among the Senecas of Allegany Reservation, N. Y., and carried 

 forward a number of other investigations dealing with Iroquois 

 problems. Miss Frances Densmore, a collaborator of the Bureau, 

 continued her study of Indian music, collecting additional songs, 

 transcribing these and songs previously recorded, and preparing ma- 

 terial for publication. The Bureau published its annual report and 

 three bulletins. The library accessioned 378 items and relabeled and 

 reshelved over 5,000 books. 



International Exchange Service. — The Exchange Service acts as 

 the official United States agency for the interchange of parliamentary, 

 governmental, and scientific publications between this country and 

 the rest of the world. During the past year the Service handled 

 576,282 packages of such publications, with a total weight of 388,649 

 pounds. Naturally, the last 2 years have shown a marked falling off 

 in the number of packages passing through the Exchange Service 

 because of war conditions in large parts of the world. The material 

 that cannot now be shipped abroad will be stored at the Institution 

 until the end of hostilities. Transmission of shipments to and from 

 Great Britain and to Latin America has been practicaly uninter- 

 rupted, and some material has been forwarded to Spain and Portugal, 

 although irregularly. Five consignments of exchanges have been lost 

 through war activities. 



National Zoological Park. — The W. P. A. project which has been 

 of such great assistance to the Park in the past few years was termi- 

 nated on August 6, 1940, so that few improvements could be under- 

 taken during the year. The four new waterfowl ponds were com- 

 pleted and birds transferred to them at the beginning of the year. 

 The new restaurant constructed by the P. W. A. was completed in 

 the fall of 1940 and was opened to the public in March 1941. Visi- 

 tors for the year totaled 2,430,300, including 48,050 representing school 

 or other groups from 20 States and the District of Columbia. The 

 Smithsonian-Firestone Expedition to Liberia for the purpose of 

 collecting live animals for the Zoo returned to this country in August 

 1940. The animals brought back numbered nearly 200, representing 

 61 species of mammals, birds, and other forms, several of them being 

 new to the history of the collection. The usual large number of 

 gifts was received during the year, and 70 mammals, 49 birds, and 

 14 reptiles were born or hatched in the Park. The total number 

 of animals in the collection at the close of the year was 2,380, repre- 

 senting 730 different species. The chief need of the Zoo is for 

 three new buildings: one for antelope, deer, wild hogs, and kan- 

 garoos ; one for monkeys ; and the third for carnivores. 



Astrophysical Observatory. — At Washington the work of the staff 

 was devoted largely to completing for publication the immense table
