GENERAL ADMINISTRATION AND PROTECTION. 57 



tions for material desired for use in connection with addresses by members of 

 Forest Service or in connection with Forest Service exhibits. 



Prints for Official and Personal Use. 



Care must be taken to distinguish between photographic material needed 

 for official use and material desired by members of the Forest Service for 

 their personal use. Photographic material for personal use will be supplied to 

 members of the Forest Service only by sale. Photographs which are to be 

 used for illustrating books or articles prepared by members of the Forest 

 Service as individuals should be regarded as for personal use, and the char- 

 acter of this use should be clearly indicated by the requisition. When new 

 photographs are developed, one set will be supplied for the use of the office 

 if requisitioned by the chief of the office, such photographs to be regarded as 

 Forest Service property. 



Photographic material may be requisitioned for outside distribution for the 

 following purposes : 



(a) To cooperators and others from whom aid has been received or by whom 

 courtesies have been extended in furtherance of official work. 



(6) For use in illustrating material to be published in newspapers or other 

 periodicals. 



(c) For use in book illustrations. 



(d) For use in educational work by lecturers and schools and for exhibit 

 purposes. 



Requisitions for photographic material of any kind to be disposed of to 

 cooperators and others who have extended aid or courtesies in the furtherance 

 of official work must be initialed by a chief of office, in the districts or in 

 Washington. Requisitions for photographic material to be given, loaned, or 

 sold for use in illustrating any book, article, or other printed matter, or for 

 use in educational work by lecturers and schools or for exhibit purposes, must 

 be initialed by the District Forester or by a chief of branch, and be approved 

 by the editor. The editor has charge of all work designed to promote general 

 education in forestry by the diffusion of information concerning forests and 

 their best use, through the supply of information to newspapers and other 

 periodicals, through the giving of addresses other than those before audiences 

 of National Forest users with regard to National Forest work, or through 

 exhibits in cooperation with schools other than technical schools of forestry. 

 All requisitions for photographic or art work which will be used to promote 

 general education in forestry must be approved by the editor. 



Lantern-Slide Collection. 



All exhibit and lantern-slide material owned by the Forest Service, whether 

 in the districts, in Madison, or in Washington, will be considered a part of 

 the Forest Service lantern-slide collection and the Forest Service supply of 

 exhibit material, and will be under the direct jurisdiction of the editor, to whom 

 will be made such periodical reports as may be called for. 



Sale of Prints. 



The act of March 4, 1907, authorizes the disposal of photographic prints 

 (including bromide enlargements), lantern slides, transparencies, blue prints, 

 and forest maps at cost and 10 per cent additional. Decision as to whether 

 or not material should be sold should be based on the same grounds as decision 

 whether material should be loaned or given away. The object in every case 

 should be to promote the work of the Forest Service or to diffuse information 

 concerning forestry as effectively as possible. Generally speaking, gifts should 

 be restricted to cooperators or persons who have extended aid or courtesies in 

 furtherance of official work; but when a valuable educational result can be 

 attained only if material can be furnished free, gifts may be made, in the dis- 

 cretion of the editor. 



Use of Prints to be Stated in Requisition. 



The geographer will see, before initialing requisitions for photographic work, 

 that the purpose for which the work is to be used is clearly indicated and 

 that the requisition conforms to the above instructions. 



Schedule of Prices. 



When material is to be sold it will be according to the following schedule 

 of prices :
