244 A NATIONAL PLAN FOB AMERICAN FORESTRY 



extensive enough to meet the nation's forest requirements, it will be 

 necessary, in order to meet such requirements, to effect a very great 

 extension in the practice of forestry and in measures to build up the 

 forest growing stock, and to protect and maintain this growing stock 

 on a sustained yield basis. In addition to the desirability of assuring 

 adequately that the requirements of the United States for timber 

 products and other forest uses and services will be met, w r e have the 

 economic incentive for making constructive use of a huge area of 

 forest land which by and large is not susceptible of any other major 

 commercial use.
