wise have been found in the fall inspection. At the present 

 writing the trees in the worst-infested sections of the residential 

 district have been cleared of the gypsy moth nests up to the snow 

 line, and about two-thirds of the street trees cleared of both 

 gypsy and brown-tail moths. A great deal of cutting of brush 

 along infested roadsides has been carried out under the direction 

 of the local superintendent. 



Waltham presents one of the serious problems of the in- 

 fested district, as where the gypsy moth has been neglected 

 it has increased remarkably in the past two years. The wood- 

 lands are generally infested, and some of the colonies have 

 reached dangerous proportions. The city has a costly moth 

 problem before it, and much careful and thorough work must 

 be carried on in 1907, if a gain is to be made against the insects. 

 In the work at Waltham we have had the continued assistance 

 and co-operation of the local authorities, and, if suitable funds 

 can be provided for the 1907 operations, a good showing will 

 be made by the close of the year. 



WATERTOWN. 

 JOHN C. FORD, Local Superintendent. 



The principal work in this town has consisted of cutting 

 brush and the general clearing up of infested roadsides on the 

 principal streets, burlapping and spraying trees in Whitney 

 Hill Park, the removal of worthless trees, and the cementing 

 of cavities in those which have become decayed. The street trees 

 show an improved condition over 1905 ; but little gain against 

 the gypsy moth has been made on private estates, owing to in- 

 effective local work or work done by irresponsible contractors. 



At the Watertown arsenal grounds, which have been badly 

 infested, a remarkable improvement has been made, largely 

 owing to the personal interest and efforts of the commandant. 

 At the present writing the work of clearing the street trees is 

 in progress, and should be nearly completed by January 15. The 

 work next season should include the general use of the burlap 

 over the town, and the spraying of trees in the most badly 

 infested sections.
