30 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1916. 



The publications of the bureau issued during the year comprise 

 two annual reports with their accompanying papers, and two bulle- 

 tins. In press or in preparation at the close of the year were three 

 annual reports and five bulletins. The bureau library was enriched 

 by the addition of 1,078 volumes, among them 20 volumes of Bibles 

 and portions of the Bible in American Indian languages. 



INTERNATIONAL EXCHANGES. 



The total number of packages of governmental and other docu- 

 ments handled by the International Exchange Service during the 

 year was 301,625, an increase of 25,869 over the previous year. This 

 figure, however, still shows a decrease as compared with the total 

 handled in 1914, owing to the suspension of shipments to 10 countries 

 involved in the European w^ar. Efforts have been made to resume 

 shipments to certain of these countries, which have met with some 

 degree of success in the case of Germany and Eussia. 



The Exchange Service has continued its policy of international 

 helpfulness by assisting governmental and scientific establishments 

 to procure publications especially desired both in this country and 

 abroad. One instance showing the value of this policy may be cited. 

 The Pan American division of the American Association for Inter- 

 national Conciliation, of New York, wished to assemble a collection 

 of several thousand volumes of North American origin for presen- 

 tation to the Museo Social Argentino at Buenos Aires. Through the 

 Exchange Service the matter was brought to the attention of the 

 proper establishments and several hundred governmental and other 

 publications were received for the proposed collection. 



The number of sets of United States governmental documents sent 

 through the Exchange Service to foreign countries has been reduced 

 from 92 to 91, owing to the discontinuance of shipments to the gov- 

 ernment of Bombay at the request of that government. 



NATIONAL ZOOLOGICAL PARK. 



The National Zoological Park is becoming each year a greater and 

 greater attraction to the public, and as its collections increase so does 

 its value become of more importance as a source of information to 

 the zoologist in his stucl}^ of animal life. 



There is now in the park a total of 1,383 individual animals, rep- 

 resenting 360 species, as shown by the detailed census in the report 

 of the superintendent. 



Among the recent accessions may be mentioned a pair of young 

 lions, a pair of Siberian tigers, a great red kangaroo, several mon- 

 keys, and a number of interesting birds, but the newly acquired ani-
