people of the State is not only justifiable but most desirable, for 

 it was established for just that purpose; and no one who incurs 

 loss by insect ravages can excuse himself for that loss except on 

 the ground of ignorance that such assistance can be obtained. 



Over eight hundred of these circulars were sent out to the 

 newspapers, granges and other organizations of the State,

 over the State. It has probably been introduced from several 

 other States, as there is nothing except the objections of 

 purchasers to prevent its being brought in on every plant

 inspected and no scale found. This action was most incon- 

 venient for Massachusetts nurserymen, who were often thus 

 prevented from tilling orders to go to States having such 

 laws. To meet this difficulty, the committee of the trustees
