by the gypsy moth has been prevented by the use of thorough 

 control measures. In the late winter and early spring trees on 

 private property were thoroughly cleared of the pests, and a 

 considerable amount of most excellent work was done in put- 

 ting old orchards in good condition for spraying and burlap- 

 ping. About 65,000 burlaps were applied and attended during 

 the summer, over 30,000 caterpillars being killed in this way. 

 About 80 per cent, of the caterpillars taken were in the wood- 

 land, a fact which reflects great credit on the good work done 

 in the residential sections in 1906. 



The fall inspection of the residential district has been com- 

 pleted, and shows great gain over last year, only 314 egg clus- 

 ters being found. The woodland inspection is now in progress, 

 and a large number of scattering nests have been destroyed. 



In the course of the summer's work an important colony on 

 South Main Street, where 383 egg clusters had been destroyed, 

 was sprayed so thoroughly that not a single caterpillar was 

 taken there under the burlaps. At the Wignot colony in South 

 Natick, where 802 egg clusters were destroyed, the spraying 

 was so effective that only a single caterpillar was found later. 

 The work against the moths in Natick has been ably adminis- 

 tered, and has not suffered from lack of sufficient financial sup- 

 port at any time. The most important problem on hand here 

 at present is the condition of woodlands in the northern part of 

 the town along the Weston line, where co-operative work be- 

 tween the two towns will be necessary. We have assurances 

 from the Weston authorities that the colonies over the line in 

 that town will be thoroughly treated before the opening of the 

 caterpillar season.

The gypsy moth has become well established in nearly every 

 portion of this town. Early in the year the street trees were 

 cleared of the moths, and in the latter part of June the work of 

 cleaning private estates and certain important woodland colo- 

 nies was under way. A number of infested orchards were thor- 

 oughly treated, and at the opening of the caterpillar season 

 more than 35,000 burlaps were applied to the trees in the in- 

 fested districts. A careful attention to the burlaps reduced the
