If insects appear in alarming numbers in the forest, specimens, 

 together with an account of their habits, should be sent to the 

 Bureau of Entomology of the Department of Agriculture for identi- 

 fication and suggestions as to their destruction or control. 



The greatest enemy of the chestnut, as of other forest trees, is fire, 

 from which it should at all times be fully protected. 



Approved.
