supposed he did. But whether he does or does not feed, 

 his organs of taste and smell are rather obsolete or disused, 

 for we are able to state, from observation, that many kinds 

 of odorous bodies which are obnoxious to many insects are 

 not so to him. 



I have tried camphor upon the tree, watered it with so- 

 lution of soap and of tobacco, and I don't know that he 

 was disturbed any further than he would be mechanically 

 by their application. 



I might here notice the inadequacy of other measures 

 which have been recommended to frustrate his operations, 

 but prefer to proceed to a statement of those means which 

 will ensure success, if persevered in, and prove satifactory. 

 As the notion is prevalent that he crawls up the body of 

 the tree, I would state that he flies on to it, and, therefore, 

 it is useless to apply any preventative to keep him from 

 ascending that way. 



I am free to state, that this insect cannot be combatted 

 without labor, and the result secured, will very far more 

 than compensate for all labor bestowed, even in a pecuniary 

 point of view. 



Believing, from my observation, that he cannot be suc- 

 cessfully opposed by preparations of soap, and infusions of 

 odorous bodies thrown on to the tree, by means of a 

 syringe, I proceed to state the course which has been fol- 

 lowed with success, so far as I know. 



Our rule of action should be, direct aggi^ession upon him, 

 both in the beetle and larva forms. In the pupa stage he 

 lies in the ground secured from our search.
