gypsy moth was taken in the summer of L939. These men also ex- 
amined selected areas in Middlesex. Morris, Passaic, Somerset, Sussex, 
and Warren Counties. A total of 6,706 acres of woodland and more 
than 33.750 fruit and shade tree- were examined. No evidence of 
the gypsy moth was found. 
Work in Pennsylvania was confined chiefly to sections of the cen- 
trally infested area not scouted Last year and to intensive scouting 
and necessary treatment at sites of infestations previously located 
in lightly infested territory and similar work at sites of assembling 
cages where moths w^ere taken in July and August 1939. In scouting 
the lowlands along the Susquehanna and Lackawanna Rivers lying 
within the infested area. 1 infestation consisting of 58 egg clusters 
was located and treated in the township of Pittston. Spraying of 
the infested residential areas was begun May 21 and 2,351 individual 
properties were treated. Fifteen of the 28 sprayers used in wood- 
land spraying, which was begun on June 3, were operated on the 
double-shift basis and the remaining 13 machines were operated 
throughout the season on the single-shift basis of 8 hours' daily 
employment. 
In October and November 1939, federally supervised gypsy moth 
projects using labor furnished by the National Youth Administration 
began operations in Luzerne and Lackawanna Counties, Pa. 
Together these projects provided for the monthly employment of 
320 workers. These workers were divided into 3 groups for each 
county and were furnished 48 hours of employment each month. 
Although considerable difficulty was experienced with these men at 
the beginning of the work, this was gradually overcome and much 
good work was done, although close supervision by thoroughly experi- 
enced regular employees was necessary at all times. Beginning in 
December, 9 workers employed on the basis of 3 equal shifts monthly 
were detailed to work in the repair shop at Wilkes-Barre. 
In October a Department of Public Assistance project sponsored 
by the Bureau of Plant Industry of the Pennsylvania Department 
of Agriculture was started in Pittstown Township, but the project 
was disappointing because it was found impossible to obtain a 
sufficient number of workers willing and qualified to do the work 
assigned them. In May 1940, when this project was terminated, less 
than 43 percent of the man-hours of labor promised in the projec t 
application had been furnished. Worthless brush and debris on the 
forest floor of 217 acres was cut and disposed of by these Workers 
during their period of employment. 
In the enforcement of the Pennsylvania quarantine on account 
of the gypsy moth, 16.089 shipments from the lightly infested area 
were allowed to move on permits issued after it had been deter- 
mined that there was no danger of transporting infestation. In the 
generally infested area 19,029 shipments were thoroughly inspected 
before certificates were issued authorizing them to be moved. Sixty- 
one warnings were issued to first-time violators of the quarantine, 
and there were 3 individual instances of the successful prosecution 
of shippers who failed to heed the warnings issued to them. Effec- 
tive November 15, 1939, a Pennsylvania State quarantine revision 
eliminated quarantine restrictions on the townships of Canaan in 
Wayne County, Carbondale in Lackawanna County, and Jackson in 
2077.-'; -40 3
