scale, the gypsy moth, and the brown-tail moth. The sea- 

 son under consideration has shown that at least one of these 

 pests — the elm leaf-beetle — is already thoroughly established 

 in the heart of the state, far to the northward of where we 

 should expect it to make its first appearance, while I have 

 known for two years that another — the brown-tail moth — 

 had at one time gained a temporary foothold within our bor- 

 ders, though, thanks to the Massachusetts Gypsy Moth Com- 

 mission, it was apparently destroyed before spreading. We 

 can hardly hope long to escape serious injury from these 



insects, and it is of 

 the greatest import- 

 ance to the state that 

 our citizens be on 

 the lookout for the 

 first appearance of 

 each of them. 



For several years 

 there has been rea- 

 son to expect that 

 the Imported Elm 

 Leaf - Beetle,^ — 

 which has been so 

 troublesome in other 

 states, would attack 

 the elm trees along 

 our southern bor- 

 ders, although there 

 seemed to be some 

 reason to hope that 

 it would not flourish 

 in the central and 

 northern parts of 

 the state. It was 

 something of a sur- 

 prise, therefore, to
