No. 4.] THE GYPSY MOTH. 365 



in any of the towns in eastern Massachusetts, and these two 

 factors have been of grave importance in preventing the 

 extermination of the moth here. In spite of these obstacles 

 notable progress towards extermination has been made in the 

 residential district. In the northern part of the town limited 

 infestations have been found in the brush and woodland 

 areas. The whole town should be carefully inspected before 

 the hatching period, and all infestations put in shape for 

 exterminative measures. If this cannot be done, extensive 

 colonies may develop here ; if it can be done, and these 

 measures applied, the extermination of the moth from Bel- 

 mont will not be difficult of accomplishment. 



Boston. — In Dorchester and Roxbury but 5 caterpillars 

 were taken under the burlaps. In South Boston three times 

 the area was burlapped the past season that was covered in 

 1898. The burlaps were carefully attended, and no trace 

 of the moth was discovered throughout the entire season. 

 Three former colonies in East Boston have been apparently 

 exterminated. At Orient Heights the infested vacant lots 

 have been cleared up, the fruit and shade trees trimmed, 

 and exterminative work is now well in hand. Boston 

 proper, Roxbury and Dorchester should now be thoroughly 

 inspected by experienced men to guard against the repeti- 

 tion of such an outbreak as occurred several years ago at 

 Sargent Street, Dorchester. This work should be done 

 early in the season, so that if an infested spot is located, 

 it can be cleared up at once before the hatching time. 



Brookline. — Since the finding of the colonies in this town 

 in 1896 sufficient time had elapsed to allow any straggling 

 moths from these colonies to increase to a point where their 

 presence could be easily detected. A thorough inspection 

 of the residential district was made last spring. As a result 

 of this examination, it seems proba])le that the infestations 

 in Brookline have now been located. A small number of 

 larvse were taken at different points in the town during the 

 past summer. At the Schlesinger colony, where a formida- 

 ble outbreak of the moth occurred in 1896, only 2 larvte were 

 found in 1899. At the Crafts colony there has been no trace 

 of the moth found in 1898 or 1899, and the insect has been 

 probably exterminated there.
