not offer any particularly serious problems in the way of con- 

 trol measures, if the moth could be suppressed in the larger 

 infested localities to the north. 



Georgetoiun. 



1899. — The Georgetown colony offered a unique problem. 

 It involved several acres of woodland, which were completely 

 stripped in the season of 1899. The land not being particu- 

 larly valuable, it was possible to cut out and burn the entire 

 colony, and to carry this heroic treatment over a consider- 

 able area lying outside of the known infested section. The 

 fall examination showed only nine egg clusters, which were 

 destroyed. 



1904. — With five years in which the insect could multiply, 

 a very careful examination of this colony failed to reveal a 

 single specimen of the gypsy moth. While it is still possible 

 that colonies may develop elsewhere in the town, from insects 

 scattered from the original colony by teams or birds, it is ap- 

 parent that the old centre of infestation, which offered one of 

 the most formidable problems the committee was ever called 

 upon to face, has been completely wiped out. 



Lexington. 



1899. — At the close of the year the woodland colonies 

 offered the most serious problems in this town. The town had 

 been thoroughly examined, and its exact condition determined. 

 In the southern part, near tlie Arlington line, several small 

 colonies were located, thoroughly treated, and put in condition 

 for exterminative work. The old colonies in the south-eastern 

 part of the town Avere in excellent condition. 



1904. — The remnants of the old colonies in the woodlands 

 have now increased to such a point that considerable stripping 

 of trees occurred the past summer. An important colony has 

 also developed near the AVoburn line, and here woodland and 

 shade trees have been seriously injured. The tree warden of 

 this town has done excellent work in suppressing the moth, 

 so far as his means would permit ; but the insect has made a 

 steady gain, and at this writing not only a large part of the 

 woodland but also a considerable part of the residential district 

 is badly infested.
