No. 4.] THE GYPSY MOTH. 375 



tery, which, from the immense amount of travel centring 

 there, will probably remain slightly infested so long as the 

 moth is abundant in the inner towns. No egg-clusters were 

 found in the fall inspection. As the danger of reinfestation 

 decreases, faithful attention to the burlaps, with an occa- 

 sional search for eggs, will be the only work necessary in 

 Watertown. 



Wintlirop. — During the season of 1899 all the trees in 

 this town were burlapped, and received close attention. A few 

 scattered larvae were found. A careful examination at the 

 end of the burlap season disclosed but a single egg-cluster. 

 The town is now practically cleared of the gypsy moth. In 

 common with other similarly located towns, Winthrop is 

 somewhat exposed to the danger of reinfestation from the 

 central district so long as the moth remains there in numbers. 



Wohurn. — The greater part of the residential district was 

 burlapped and carefully attended during the summer. In 

 one colony, where caterpillars were so numerous in 1897 as 

 to necessitate burning with oil, no form of the moth was found 

 this year. All told, a smaller number of caterpillars were 

 destroyed this year than last, and but few egg-clusters were 

 found in this section during the fall inspection. The northern 

 portion of the city has not been scouted since 1895 until this 

 fall, when a few small colonies were found. With but little 

 effort these colonies can be put in shape for exterminative 

 work. All the known woodland colonies are either entirely 

 or nearly exterminated. In one woodland colony in 1898 

 392 caterpillars were destroyed ; and in the same colony in 

 1899 only 3 were found. In another, 70 caterpillars were 

 destroyed in 1898, and no form of the moth was found in 

 1899. There still remains an area in the northern portion 

 of the city wdiich should be inspected again. 



Central Towns. 

 Everett. — Limitations of funds at critical periods have at 

 times prevented the employment of active measures in this 

 city, and, as a result, the condition is but slightly improved 

 over that of former years. The infested areas are well known, 

 and if circumstances enable us to make a thorough search 

 for eggs before the hatching period, a large part of the city 

 will be in condition for exterminative work in 1900.
