294 BOARD OF AGRICULTUTE. [Pub. Doc. 



and the extermination of the moth can be accomplished, an 

 expense will be stopped which must otherwise be constantly 

 increasing and which must be borne annually for an indefi- 

 nite period either by the State or by all residents of the 

 country over which the moth would extend its constantly 

 widening range. 



Encouraging progress toward extermination has already 

 been made with manifestly insufficient funds and in the face 

 of many obstacles. The numbers of the moth have been so 

 reduced that no material damage has been done Ijy it during 

 the past two years. It has been exterminated first from 

 single trees, then from orchards, woodlands and entire 

 towns. More than eight hundred infested localities have 

 been entirely freed of its presence. This work was begun 

 on the borders of the infested region and has progressed 

 toward the centre until the moth appears now to have been 

 exterminated from more than one-third of the region infested 



in 1891. 



Respectfully submitted, 



E. H. FORBUSH.
