Thorough work cleaned up these small infestations during the following year, and repeated scouting has failed to indicate the presence of the pest. In the meantime intensive work was carried on in the central part of the infested area, and more than 3,000,000 egg clusters were treated the first season. The trees on several acres were not only completely defoliated at the time the colony was discovered, but many were dead and others were in a dying condition. This intensive work pre-. FiGTRE 5.—Blue spruce defoliated aud killed by tlic gipsy moth vented defoliation the following season; in fact, no trees have suf- fered from gipsy-moth feeding in New Jersey since that time. Dur- ing the next four years the scouting and clean-up operations were continued throughout the entire area known to be infested, particu- lar attention being paid to a series of extensive w^oodland areas north of Somerville, known as the Watchung Ridges. These areas were by far the most difficult and expensive part of the territory to handle properly, as many square miles of woodland were involved. Substantial progress was made as the work proceeded. The density of the infestation in 1921 is indicated on the map in Figure 6. Since 1925 continuous progress has been made in cleaning up and exterminating the gipsy moth in New Jersey. It has been necessary to operate in an area embracing 2,369 square miles, and the towns in the area where colonies have been found cover 924 square Please note that these images are extracted from scanned page
