FOREST SERVICE. 227 



The use of the librarj' was markedly greater this 3^ear than last. 

 Monthly announcements of all new forest literature receiA-od are 

 regularly and prominently posted on the Service and library room 

 bulletin boards. The library committee is now preparing for publi- 

 cation, in cooperation with the general library of the Department, a 

 classified list of forest literature. 



FOREST PHOTOGRAPHS AND LANTEEN SLIDES. 



The photograph collection contains 19,052 photographs, of which 

 5,192 were catalogued and filed during the past year — 808 more pic- 

 tures than were added during the previous yearr The total collection 

 comprises pictures from 43 different States and Territories and 9 

 foreign countries. 



Lantern slides in the collection number 2,881, of which 561 were 

 added during the year. 



Duplicate photographs (mainly unmounted) to the number of 

 4,137 were given to 47 educational institutions, to 52 applicants for 

 illustrations to be used in books and articles on forest subjects, and to 

 39 individuals who had extended assistance and courtesies to mem- 

 bers of the Service doing field work, or were exchanged for sets of 

 views from 4 foreign countries. Selections of lantern slides, num- 

 bering in all 1,861, were loaned for educational purposes. 



As an aid to filling gaps in the collection and to prevent duplica- 

 tion, a map was prepared showing by counties the number of photo- 

 graphs already filed. 



EXPOSITIONS. 



The exhibit described in the last report of the Forester was dis- 

 played at the Louisiana Purchase Exposition until its close, Novem- 

 ber 1, 1904, when most of the material was safely returned to Wash- 

 ington. A few articles were shipped to Portland, Oreg., in antici- 

 pation of use at the Lewis and Clark Centennial Exposition; a large 

 glass case and contents, illustrating methods of turpentining, was 

 loaned to the museum of the College of Pharmacy, St. Louis, Mo., 

 and all of the living trees and nursery stock, comprising the outside 

 tree-planting exhibit, were presented to the Missouri Botanic Garden, 

 St. Louis. 



For the Lewis and Clark Centennial Exposition a practically new 

 exhibit of the Forest Service was prepared. This was installed, to- 

 gether with the exhibit of the Reclamation Service, in a special Gov- 

 ernment building. Approximately 5,600 feet of floor and wall space 

 was devoted to the forest exhibit. The two displays were planned 

 to show clearly the direct and vital relationship between the fields of 

 the two organizations, which, especially in the West, work hand in 

 hand to secure, in the interest of the people at large, the wood and 

 water resources of the country against waste and monopoly. The 

 forest exhibit was ready and open to the public on the opening day 

 of the exposition, June 1, 1905. The cost of preparing and installing 

 it was approximately $7,600. Large colored and uncolored trans- 

 parencies and colored bromide photographs effectively illustrated 

 forest conditions and problems and the work of the Forest Service 

 throughout the country. Maps, charts, instruments, models, wood 

 specimens, and a timber-testing machine in operation were also
