conduct original investigations in the forest and laboratory to deter- 

 mine (1) the principal insect enemies of forests and forest products; 

 (2) the character and extent of the problems which, on account of the 

 losses involved, demand special attention; and (3) the more important 

 facts in the life and habits of the destructive insects, local forest man- 

 agement, lumbering operations, beneficial insects and other natural in- 

 fluences upon which to base conclusions and recommendations relating 

 to practical methods of preventing losses.
