ately adjoining residential sections, will furnish annually the 

 caterpillar swarm to reinfest the estates previously cleaned of 

 the moths ; hence it is most important that neither time nor 

 money should be spared in wiping out the gypsy moth in the 

 woodlands. 



Prospect Hill Park, a block of some 165 acres, is thoroughly 

 infested, and a considerable amount of defoliation has occurred 

 here, particularly in 1907. Co-operative work between the city 

 and State is already in progress here, with the object of bring- 

 ing the moths thoroughly under control. There is also under 

 consideration a plan for co-operative work between the large 

 owners of woodlands, the city and the State, to the end that the 

 incipient moth colony in these woodlands may be suppressed. 



During the coming season, besides the usual preparatory work 

 in orchards, numerous worthless trees should be cut and burned, 

 and a thorough cleaning made of infested roadsides not previ- 

 ously attended to. 



Much burlapping and spraying will be required in the resi- 

 dential district, as well as the use of sticky bands ; and spray- 

 ing will give good results in the woodlands, which have been 

 thinned out and put in condition for economical work. 



We are glad to say that in this city the field operations have 

 had adequate financial support by the city government, and the 

 work, as far as it has gone, has been well administered. 



WATERTOWN. 

 JOHN C. FORD, Local Superintendent. 



A gain has been made in this town during the past year, and 

 the work of controlling the moth pests has been successful. The 

 present methods used in thickly settled districts have been em- 

 ployed as needed, and have given fairly good results. Local 

 considerations at times have made it impossible to apply these 

 methods of work in season and in the most efficient way, other- 

 wise a much greater gain in reducing the number of the moths 

 would have been made. 



In the early part of the year a force varying from 15 to 45 

 men was employed in clearing street trees and those on private 

 estates, while a considerable amount of work was done in Whit-
