LYNN. 



A. C. DOAK, Local Superintendent. 



About February 1, arrangements were completed for a thor- 

 ough campaign against the moths in this city, - - a date altogether 

 too late, in view of the general infestation existing here. Mr. 

 Doak employed a large gang of men, and entirely covered the 

 street trees and private estates in the residential district. A 

 very general infestation was found, and, considering the short 

 period of time available before the hatching season, the results 

 of this work showed in an especially gratifying manner. The 

 usual campaign of spraying and burlapping was vigorously 

 prosecuted, with good results. 



Lynn has been peculiarly exposed to continued infestation 

 by the gypsy moth, because of the neglect of the large colonies 

 existing in the Lynn Woods, which are now entirely and seriously 

 infested. Hundreds of acres in these woods were stripped by 

 the caterpillars during the past year, with the result that many 

 fine pines, oaks and other trees have been killed. So severe 

 was the caterpillar plague in this district last year that we were 

 obliged to request the mayor to close the park to the public, 

 which was done for a period of about two months. 



Early in the fall an arrangement was completed between the 

 Lynn park board and the Lynn water board and the State for 

 special co-operative work, to reduce the pest in the Lynn Woods. 

 The first effort to be made is naturally that of protecting the 

 park roads, so as to reduce as far as possible the scattering of 

 the caterpillars on vehicles. To this end upward of 100 men have 

 been employed in thinning strips 75 feet wide along the prin- 

 cipal roads, thus permitting of economical spraying operations 

 next season; and this work is now organized in a satisfactory 

 manner. The superintendent is strongly of the opinion that, 

 unless a large sum of money can be expended in the Lynn
