forestry with an ex]icrimcntal tract of 30,000 acres, is another evidence of 

 the importance of our forest resources. The general interest in forest 

 e.xploitation, using the term in a strictly economic sense, is attested farther 

 by the fact that the demand for com])etcnt foresters by both federal and 

 state governments ;unl ])ri\ale inilividuals, is far in e.xcess of the supply. 

 The trentl of the times points to a more scientilic, careful administration of 

 forest areas, and it logically follows that th(; insect enemies of our trees 

 should be the subject of more extended investigations for the special 

 purpose of ascertaining some practical methods of controlling the more 

 dangerous species on wild land. This work, in bringing together many 

 -scattered records, should prove of great value in all subsecjuent studies 

 along these lines.
