in Rensselaer County, X. Y. Territory under suspicion should be 
scouted within the next year or two so that infestations existing there 
may I ><* located and exterminated before spread from them occurs. 
Seven heavy-duty sprayers, operated on the double-shift basis of 
6 hours for each shift, were used during June in spraying the most 
serious infestations discovered in the Massachusetts /.one area during 
the year. 
Except for a small amount of selective thinning at the site of an 
infestation in West Hartford. Hartford County, all scouting and 
treatment work in Connecticut was confined to the barrier zone, par- 
ticularly in Litchfield County. Because of the wind spread in the 
fall of 1938 and Spring of 1939 previously referred to. condition-, 
at least in the northern portion of the Connecticut zone area, arc 
about the same as in Berkshire County. In addition to this ab- 
normal wind spread, infestations established several years a«ro in 
northern Litchfield County towns are gradually increasing because 
scarcity of relief labor for W. 1*. A. assignment and lack of regular 
funds for the employment of per diem labor make it impossible to 
do urgently needed work. Good progress has been made in eradi- 
cating the isolated infestation found last year in Southbury, X»"a 
Haven County. A small infestation in the city of New Haven re- 
ported by the Connecticut Agricultural Experiment Station this 
spring has been intensively scouted, and treatment, including spray- 
ing, has been applied. Eight heavy-duty sprayers, two of which 
were operated by a force of C. C. C. workers detailed from Camp 
Cross in Sharon, were used in the Connecticut barrier zone in June 
in treating the most serious infestations found during the year. 
Although all these sprayers began work on the double-shift basis 
of 6 hours for each shift, resignations in the W. P. A. force made 
it necessary after the first week to operate three of the machines on 
the single-shift basis of 8 hours. 
Federal W. P. A. forces. Civilian Conservation Corps camp en- 
rollees. and State employees supervised by the New York Conserva- 
tion Department scouted and applied necessary treatment in areas 
considered most dangerous in Rensselaer, Columbia, Dutchess, and 
Putnam Counties within the zone and in Essex. "Warren. Saratoga, 
Albany. Ulster. Rockland, Westchester, and Nassau Counties to 
the west and south of the 1 zone. Although numerous scattering in- 
festations resulting from the wind spread previously mentioned 
were found in a strip of town- paralleling the Massachusetts State 
line in Rensselaer and Columbia Counties, all were small and many 
no doubt have already been exterminated. Considerable additional 
work i> needed in these two counties to complete the area and locate 
and treat any existing infestation.-. In spraying the most serious 
infestations discovered during the year the New York Conservation 
Department used 11 machines. () of which were temporarily loaned 
by this project, a- they Were badly needed in treating area- in that 
Stale and a sufficient supply of Lead arsenate was not available for

Although no Federal gypsy moth work was carried on in NVw 
Jersey during the year, a small force of State employees scouted 
intensively :it the site of an attracting cage in Englewood Boro, 
Bergen Count v (near George Washington Bridge), where a male
