 Srotia and New Brunswick, over all of Rhode Island, ball of Connecti- 

 cut, and into New York. The brown-tail moth has accompanied the 

 ijipsy moth in its work of destruction. 



The brown-tail moth spreads locally by means of flight, mostly; 

 but may be carried great distances commercially, on shipments of young 

 trees bearing young caterpillars in their winter nests. The first nests 

 found in Connecticut came on fruit tree seedlings imported in 1909 

 from a French nursery. .(Britton.) The pest has several times reached 

 nurseries in Illinois on young trees from Belgium and France, but has 

 each time been eradicated by the state inspection service before it 

 could spread from the nurseries. In 1921 the federal inspectors inter- 

 cepted nests of the brown-tail moth on forty-two shipments from 

 France, and egg masses of the gipsy moth on one shipment. 



These two pests have been fought most vigorously but are not yet 

 under complete control. It is worth while to give here an account of 

 the expenditures made up to date (April 5, 1922) in the fight against 

 the gipsy moth and the brown-tail moth. Mr. A. F. Burgess, who is in 

 charge of the work, has kindly furnished these figures.
