Walden Pond, and areas in Revere, Belmont, Watertown, and western 
Cambridge. 
Scattering infestation, that is, the occasional or fairly general 
occurrence of the larve of the gypsy moth, without, however, result- 
ing in complete or notable stripping of the street trees and forests. 
was found through much of the southern half of the Fells reservation, 
and practically throughout the towns lying within the area of worst 
infestation indicated, and as far south as the Charles River. Exterior 
to this area of general infestation, scattering presence of the gypsy 
moth was found in Lexington, Winchester, and Woburn to the north- 
west; in Stoneham, Wakefield, Saugus, and Reading to the north; 
and in Peabody, Salem, Beverly, Marblehead, and Lynn to the north- 
east. To the west, Arlington, Belmont, Watertown, and Cambridge 
-west of Harvard Square are much infested. In Newton there are 
perhaps some twenty-five small points of infestation, as reported by 
the street commissioner, Mr. Ross. Very good work in the way of 
control has been done in this town, and with the exception of the new 
colony located near Newton post-office, on the Van Etten estate, only 
scattering larva’ were found. The colony just referred to was dis- 
covered last year (1903), and represents a spot of bad infestation, 
covering a considerable area of garden, orchard, and ornamental 
plants. In the southern portion of Newton is located one of the 
worst of the outer colonies found during the course of the work of the 
gypsy moth committee. This colony, near the intersection of Dedham 
and Parker streets, originally covered several hundred acres of wood- 
land, and was made the subject of very thorough extermination work 
by the committee. This work has since been followed up to some 
extent under the direction of Mr. Ross. <A careful examination of 
this area shows much of it still free from the gypsy moth, but ocea- 
sionally larve were found, showing that there is still a scattering 
infestation here and there which in a few years will be sufficient to 
repeat the damage of 1896, when the colony was first located. No 
larve were found in 1902 or 1903 in the area covered by this colony, 
and the insect is evidently, therefore, just beginning to get a new 
start. In South Boston the gypsy moth has increased very little, and 
the extermination of several of the worst colonies seems to have been 
effected. This is true of the Dorchester colony (Sargent street), 
where a considerable residential area, including also some forested 
hillsides which were badly infested in 1898, shows now no examples 
of the insect. The infestation still exists in the residential district at 
West Cottage street, Dorchester. In the old colonies examined at 
Brookline no larve or other indications of infestation were found. 
One of the most interesting features of the investigation was the 
demonstration that in a good many areas the careful work of the 
gypsy moth committee has resulted in the extermination of the insect.
