REPORT 



SECRETARY OF THE SMITHSONIAN INSTITUTION 



CHARLES D. WALCOTT, 



FOR THE YEAR ENDING JUNE 30, 1911. 



To the Board of Regents of the Smithsonian Institution: 



Gentlemen : I have the honor to submit a report showing the 

 operations of the Institution and its branches during the year ending 

 June 30, 1911, including the work placed by Congress under the direc- 

 tion of the Board of Regents in the United States National Museum, 

 the Bureau of American Ethnology, the International Exchanges, 

 the National Zoological Park, the Astrophysical Observatory, and the 

 United States Bureau of the International Catalogue of Scientific 

 Literature. 



The general report reviews the affairs of the Institution proper, 

 with brief paragraphs relating to the several branches, while the 

 appendix presents detailed reports by those in direct charge of the 

 work. Independently of the present report, the operations of the 

 National Museum and the Bureau of American Ethnology are fully 

 treated of in separate volumes.
