46 GOVERNMENT FOREST WORK. 



of National Forest lands under special-use permits, 

 the development of recreational resources within the 

 National Forests, the exchanges of National Forest 

 lands and timber for lands in private ownership 

 within the National Forests, and the administrative 

 work connected with the purchase of forest lands in 

 the eastern United States. 



The Branch of Research has supervision over the 

 investigative work of the Service, including silvicul- 

 tural studies, studies of State forest conditions, 

 investigations of the lumber and wood-using indus- 

 tries and lumber prices, and the investigative work 

 carried on at the Forest Products Laboratory and the 

 forest experiment stations. 



The Branch of Engineering administers water- 

 power permits and easements granted prior to the 

 passage of the Federal Water power act, and makes 

 such power investigations and reports as are re- 

 quested by the Federal Power Commission. It is also 

 charged with the making of such surveys and maps 

 as are necessary to the National Forest work. It 

 administers for the Forest Service the provisions of 

 the National Forest road appropriation acts and 

 supervises the construction of such roads and trails 

 as are handled by the Forest Service. Practically all 

 civil-engineering work in the Service is now handled 

 by this Branch. 



The Branch of Public Relations devises and de- 

 velops means of contact with the public, to the end 

 that the services which the Forest Service is prepared 

 to render may be better known and more generally 

 made use of. These means include official publications, 

 information for the press, information and material 

 for use in schools, and forestry exhibits and motion 

 pictures. The Branch gives particular attention to en- 

 listing the cooperation of the public in the prevention 

 and control of forest fires.
