REPORT OF THE SECRETARY 83 



The development and printin^f of all photographic work was done 

 in the laboratory of the United States National Museum by Dr. A. J. 

 Olmsted in cooperation with the bureau in exchange for work done 

 by Mr. Gill for other branches of the Institution. This arrangement, 

 as in the previous 5'ear, has proved eminently satisfactory. 



LIBRARY 



The reference library has continued under the care of Miss Ella 

 Leary, librarian, assisted by Mr. Thomas Blackwell. The library con- 

 sists of 27,921 volumes, about 16,177 pamphlets, and several tliousand 

 unbound periodicals. During the year 780 books were accessioned, of 

 which 115 were acquired by purchase and 665 by gift and exchange; 

 also 3,980 serials, chiefly the publications of learned societies, were 

 received and recorded, of w^hich only 108 were obtained by purchase, 

 the remainder being received through exchange. A considerable 

 amount of time was given to preparing bibliographic lists for corre- 

 spondents. Requisition was made on the Library of Congress during 

 the year for an aggregate of 325 volumes for official use. An increas- 

 ing number of students not connected with the Smithsonian Institu- 

 tion found the library of service in consulting volumes not obtainable 

 in other libraries.
