removed from the centre of infestation than those heretofore 

 found, — conditions which hardly seem probable, — is not 

 so serious a menace to the success of the work as the en- 

 forced neglect, necessary in the years of diminished appro- 

 priations, of large infested woodland colonies in the central 

 district. The acreage of the outside colonies is seldom 

 large ; that of the inside woodland colonies is numbered by 

 hundreds. Outlying colonies are generally well isolated, 

 and their extermination, where sufficient funds are provided, 

 is not a matter of great difficulty. 



Condition of the Infested Region. 



The detailed description of the condition of the infested 

 towns will afford a proper basis for a summary of the con- 

 dition of the entire district. Under "outer towns" are 

 included those towns lying between the central infested 

 region and its border. The ' ' central towns " are those 

 lying nearest the centre of infestation and are most gen- 

 erally infested. 



Outer Towns. 



Arlingto7i. — The condition of Arlington shows a grati- 

 fying improvement. But few places have been found 

 infested in the residential part, and in the majority of 

 these only scattered caterpillars were taken. The wood- 

 land colonies were thoroughly worked with good results. 

 They still need thorough and repeated examinations, and, 

 if these can be given them, their extermination is assured. 

 In the fall of 1899 the entire burlapped area was carefully 

 inspected, and but few nests were found. A considerable 

 amount of territory beyond the burlaps was also inspected, 

 and three small colonies were located. These colonies are 

 restricted in area, and their extermination is not a difficult 

 problem. There yet remain a few colonies where the cavi- 

 ties in the trees should be closed and the loose bark removed, 

 and in others dead trees and brush should be cut, after which 

 all the infestations in the town will be in the best possible 

 condition for rapid extermination. 



Belmont. — There are probably more worthless, hollow 

 fruit trees and brush infested stone walls in Belmont than
