THE INTERDEPENDENCE OF FOREST 



CONSERVATION AND FORESTRY 



EDUCATION 



The economic and industrial develop- 

 ment of the western continent is compara- 

 tively recent. The abundance of the nat- 

 ural resources in the new world made the 

 consideration of their exhaustion a subject 

 of little public interest. The increasing 

 rapidity in the depletion of these resources, 

 particularly in the most populous and best 

 industrially developed of the American 

 republics, has within recent years empha- 

 sized the need of foresight in dealing with 

 them. 



The United States has been the foremost 

 of the western nations in urging the con- 

 servation of national resources through 

 better use and in enacting national and 

 state laws regulating use. When a nation 

 is new and sparsely populated the neces- 

 sary encouragement for industrial expan- 

 sion and increased population makes gov- 

 ernmental regulation of forest and other 

 natural resources less essential. There 

 comes a time, however, in the life of every 

 nation when future needs must be safe- 

 guarded from present private greed. When 

 this time comes a change must be initiated 

 in the method of handling these resources. 



The recognition of this principle caused 

 the United States in 1891 radically to 

 change her policy regarding the unoccu- 

 pied national domain and begin the estab- 

 lishment and organization of national for- 

 ests. Prior to this time practically all of 

 the forests in the entire country could be 

 exploited without regard for a second 

 crop, because nearly all timberland was
