No. 4.] GYPSY MOTH.- 227 



Lynn. 



1899. — There were practically no important moth colonies 

 in Lynn at the close of the State work. Scattering infestations 

 of small size occurred in the woodland, but were very thoroughly 

 treated during the summer of 1899. A few localities were in- 

 fested in the residential district, and these also were thoroughly 

 treated. 



1904. — The good work done in Lynn previous to 1899 has 

 been verified by the results developing in that city to date. 

 While the small infestations have now grown to moderate size, 

 the city as a whole is still in very good condition, if we except 

 the part nearest the Saugus line. In that section there has 

 been a very undesirable increase in the numbers of the moth. 

 In the northern part of the town the Lynnfield colony has ex- 

 tended southward into the wooded area, while near Walden 

 Pond there is another woodland colony of considerable size. 



Lynnfield. 



1899. — At the close of the year the town was practically 

 free of the moth. A small number of insects had been taken 

 in the southern joart of the town, but aside from that there 

 were no colonies of importance. 



1904. — A large Avoodland colony, involving 2-)erhaps one 

 hundred acres, has now developed in the southern part of the 

 town, and stretches southward over the border of Lynn. This 

 colony has made a very rapid development, and, from its occur- 

 rence near the northern border of the infested district, is one of 

 the most important in the whole list. Another colony has de- 

 veloped at North Lynnfield, but tliis has received an important 

 check through the lumbering operations which have been car- 

 ried on there. 



Manchester. 



1899. — Only sixteen egg clusters were found in the entire 

 town of Manchester this year. A single season of very thor- 

 ough work h'ud practically suppressed the large colonies found 

 there in 1898. In no place was more thorough work done by 

 the employees of the Board, and the results at the close of 1899 

 proved the wisdom of applying such measures. 



1904. — But a few specimens of tlie moth were found in 

 this town the present year. The old colonies seem to be ap-
