moth colonies existing here are a source of danger to a wide- 

 spread area. The gypsy moth has been found generally 

 scattered throughout all parts of the city, and the brown-tail 

 moth is notably abundant. A thorough inspection of the 

 city has been made, with the result that nearly every section 

 has been found infested with the gypsy moth. The largest 

 number of colonies was found in the residential section. 

 Many of them were of considerable size, over 100 nests 

 being; found on a single estate. The residential section was

cleared of the brown-tail moth nests in the spring of 1905, 

 and as a result there was but little damage by these cater- 

 pillars during the summer. 



In November and ^December the local superintendent, with 

 a small gang of men, carried on work against both insects 

 on the public shade trees. It has appeared to be difficult 

 to secure a suitable number of employees to carry on the 

 work to greatest advantage, and, as a consequence, only 

 about one-fourth of the public trees have been cleared of 

 the moths. Steps are now being taken to increase the 

 force of men, and it is expected that the entire city will be 

 covered before the egg clusters of the gypsy moth hatch, 

 next spring. A great deal of very careful work will be 

 necessary here to keep the gypsy moth under control. The 

 trees in the entire city should be burlapped next season and 

 carefully attended ; in addition, spraying will be needed in 

 the worst-infested sections.

Gypsy moths were first found in 1904 in this town. An 

 examination in the summer of 1905 by an inspector from 

 this office showed the insect to be present in about half a 

 dozen localities. The town as yet has not been completely 

 scouted, and this work should have attention next year. 

 Burlapping will be necessary on trees in the known gypsy
