REPORT OF THE SECRETARY. 21 



1, 1911. The exchange agency maintained by the Smithsonian Insti- 

 tution in Leipzig was discontinued on the latter date. 



Packages for Luxemburg and Roumania have heretofore been dis- 

 tributed through the Leipzig agency. Since its discontinuance the 

 Amerika-Institut has been good enough to assume charge of the dis- 

 tribution of packages in Luxemburg, and the Academia Romana at 

 Bucharest has been asked to act as the Roumanian exchange inter- 

 mediary. 



The Japanese Government has transferred the exchange agency of 

 that country from the Department of Foreign Affairs to the Imperial 

 Library at Tokyo. The regular series of United States official docu- 

 ments, which had been sent to the former for a number of years, has 

 also been deposited in the Imperial Library. 



The Government of the United Provinces of Agra and Oudh, 

 Allahabad, India, has, at its request, been listed to receive a partial 

 set of United States official publications, the total number of such 

 depositories being now 34. The number of depositories of full sets of 

 governmental documents remains the same as at the close of last year, 

 namely, 55. 



The Governments of the Argentine Republic, Denmark, and Great 

 Britain have entered into the immediate exchange of their parlia- 

 mentary record during the past year, 29 countries now taking part 

 in this exchange with the United States. 



Important collections of foreign publications have, through the 

 efforts of the Exchange Office, been obtained during the past year 

 for the Library of Congress and for several other establishments of 

 the Government. 



NATIONAL ZOOLOGICAL PARK. 



The accessions to the Zoological Park during the past year were 

 335 animals, and the total number of animals on hand June 30, 1911, 

 was 1,414, representing 376 species of mammals, birds, and reptiles, 

 about 20 species being new to the park. 



Among the important additions to the collections I may mention a 

 pair of northern fur seals from Alaska, a hippopotamus, an East Af- 

 rican buffalo, three prong-horn antelopes, a pair of reindeer, and a 

 large Asiatic macaque monkey. 



The number of visitors was 521,440, or a daily average of 1,428. 

 As an indication of the educational value of the park, it may be men- 

 tioned that it was visited by 169 schools, classes, etc., with 4,966 

 pupils, an increase of about a thousand over the year preceding. 

 While most of the classes were from the District of Columbia, some 

 of them belonged in various parts of the country, including all the 

 New England States, New York, Pennsylvania, and North Carolina.
