34 INDIAN FOREST INSECTS 



That the work is a comparatively simple one to put through will 

 be fairly obvious from the above descriptions of the methods necessary to 

 undertake it. Many of the head-quarter houses of the Range Officers are 

 situated in the immediate vicinity of the forests under their charge. By 

 felling a couple of trees somewhere close to the range house they would 

 be able to visit the trees twice a month without any very serious inter- 

 ruption to their executive duties. The value of the observations they 

 would thus be able to record is almost incalculable, and would result in 

 the local Forest Officer soon being placed in the possession of the life 

 histories of all his more serious pests. This of course presupposes that 

 a course of Forest Zoology is included in the education of the Range 

 Officer.
