trees and their rates of growth under 

 varying conditions of soil, heat, light, 

 and moisture. They also studied the 

 numerous dangers to which the forest 

 is exposed, and invented means and 

 established laws for its protection. In

 justment between the needs of the 

 forest and the requirements of man, 

 and in course of time laid the founda- 

 tions for a new system that was des- 

 tined to be of great importance to the 

 economic interests of nations. 



Many sciences were involved in the 

 solution of these questions. With 

 the progress in means and methods the 

 aims and objects of the new profes- 

 sion gradually grew to be more and 

 more clearly defined, and knowledge 

 and experience ultimately evolved the
