are, however, a few small colonies now in existence in Brook- 

 line, the insects probably having been brought in within recent 

 years from other infested localities. 



Burlington. 



1899. — Two small colonies of the moth were known to exist 

 in woodlands. These were treated by cutting out and burning 

 the underbrush, destroying the eggs, and putting the colonies 

 in condition for burlapping the following season. 



1904. — The woodland colonies mentioned above have, now 

 developed to small proportions, a few hundred egg clusters 

 being found in each. As yet the insects have done no particu- 

 lar harm here, but will make their depredations felt in a year 

 or two, if neglected. 



Cambridge. 



1899. — At the close of 1899 there were several small infesta- 

 tions in this city, but none of any special importance. Here 

 and there in the residential sections small colonies occurred, 

 but none which offered any serious obstacles to remedial treat- 

 ment as soon as the larger colonies in the outlying towns could 

 be suppressed. From the immense traffic through this city, 

 caterpillars were continually brought in from infested localities 

 lying to the north, and thus kept up a small although constant 

 infestation. 



1904. — The residential part of Cambridge is now quite gen- 

 erally infested by the gypsy moth. The insects have already 

 reached a point where considerable damage to trees has taken 

 place, much stripping being noticed this year in the Brattle 

 Street district, also near the Harvard Botanic Gardens, and to 

 a less extent at North Cambridge. The moth has made a rapid 

 increase in this city, although much has been done to suppress 

 it by the park superintendent and by individuals. 



Chelsea. 



1899. — A few egg clusters and caterpillars were found in 

 Chelsea in 1899. These probably resulted from straggling 

 insects brought in from Maiden and Everett. The city as 

 a whole was in very good condition. 



1904. — Several sections of the city are now quite thoroughly 

 infested. The moths are most noticeable along the main 

 avenues, near the Everett and Revere lines. The city does
