xlii THE GYPSY MOTH. 



accuracy just how successful each method is, cannot be overesti- 

 mated. The care with which the experiments at Amherst are 

 conducted guarantees the accomplishment of this most important 

 task, while the discovery of a new insecticide with the properties 

 which the arsenate of lead apparently possesses must certainly be 

 worth more to the State than all the money it has spent for the 

 extermination of the gypsy moth.
