than 100 smaller research centers. Several hundred technical men are 

 engaged in the research program. Additional temporary assistants are 

 employed in some phases of the work in accordance with demands. The 

 majority of the technical men are forestry-school graduates, but geologists, 

 entomologists, pathologists, botanists, chemists, engineers, economists, 

 statisticians, and others are also used. 



Most of the technicians employed in research have had advanced train- 

 ing; many have doctors' degrees or their equivalent. The various phases 

 of forest research require as a foundation broad training in natural science 

 with emphasis on forestry, regardless of whether the technician is to deal 

 with forest management and protection, watershed management, range 

 management, forest products, or forest economics. Advanced work — be- 

 yond this foundation training in forestry — may be in any one or more of 

 a large group of biological or other sciences, such as plant physiology, 

 pathology, entomology, ecology, soils, genetics, taxonomy, mathematics, 

 and organic chemistry.

A forest-research project. The rate of snow melt in the forest is studied with the help of 



special equipment. 



State and Private Forest Cooperation 



Some 370 million acres, or more than four-fifths of our total commercial 

 timber-growing area, are now in State or private ownership. Of this, 343 

 million acres are privately owned and include 140 million acres in farm 

 woodlands. The area under State or county ownership is continuously in- 

 creasing through public acquisition for State forest purposes and through 

 tax delinquency. 



The future of forestry in the United States depends in no small degree 

 upon acceptance and operation of better forestry practices on private lands.
