reduction in the acreage that normally would have been sprayed with the 
equipment available. 
GYPSY MOTH PROJECT 
Owing to the finding of 12 small gypsy moth infestations in Washington 
County, Maine, prior to the close of the last fiscal year a limited amount of 
work was continued in that county during the summer and fall. Egg clusters 
were found and treated in four towns, and the territory in and surrounding 
each colony was thoroughly cleaned. Four small infestations were located on 
residential property in the city of Calais and these were thoroughly treated. 
This work concluded the plan for the gypsy moth AV. P. A. project in Maine. 
While this work was being carried on, inspectors from the Entomological 
Branch of the Department of Agriculture in Canadii examined territory on the 
east side of the St. Croix River, Charlotte County, New Brunswick. The gypsy 
moth has been found in small numbers on 15 properties in that county. Eight 
of these were in St. Stephen, the largest infestation being 12 egg clusters: 
3 in ^Nlilltown, the largest infestation being 8 egg clusters ; and 4 were small 
infestations in adjoining territory. 
In New Hampshire the special scouting work in 26 towns and grants in 
Coos County was finished in July 1936, and no infestation was discovered. A 
small amount of work was done along the Connecticut River from Lancaster 
south to the Massachusetts line, and after this was finished the work in New 
Hampshire was discontinued. 
Practically all of the P. A. work in Massachusetts and Connecticut was 
carried on west of the Connecticut River. In Vermont considerable infestation 
was found from Barnet south to the Massachusetts line but this decreased 
toward the barrier zone. No infestation was discovered north of Barnet or 
within the barrier zone area, and the isolated infestations located in Essex, 
Cliittenden County, and Derby, Orleans County, during 1936 were examined 
but no trace of the insect was found. 
In the Massachusetts portion of the zone, conditions are more satisfactory 
than for many years, but there is much infestation in certain localities between 
the barrier zone and the Connecticut River that seriously threatens work in 
the zone. This is particularly true in Deerfield, Northampton, and Russell, 
where sizeable areas were defoliated by the gypsy moth this summer. 
The scarcity of relief labor available for this project in the Connecticut 
barrier-zone area has limited the amount of work that could be done there, 
particularly in Litchfield County and in the northern half of Fairfield County. 
Conditions in the Connecticut zone area are therefore not so satisfactory as in 
Vermont and Massachusetts. Except in the town of Granby, where heavy 
feeding occurred this year, infestation between the barrier zone and the Con- 
necticut River is not so heavy as in the other two States mentioned. 
In New York intensive scouting was done by W. P. A. forces in Wash- 
ington, Rensselaer, Dutchess, and Putnam Counties within the zone area 
and in Albany, Westchester, and Putnam Counties to the west and south 
of the zone. No infestation was discovered as a result of this work, but in 
Putnam Valley, Putnam County, and in Shawangunk, Ulster County, sizeable 
infestations were found. The infestation in Shawangunk was located by 
employees of the New York Conservation Department after male moths had 
been t^iken at one of the assembling cages put out in that locality. The 
Putnam County infestation was discovered by men from the Civilian Con- 
servation Corps scouting a section of that town. W. P. A. forces assisted 
in the intensive follow-up work, including selective thinning of favored food 
species and spraying at each of these infested sites, and in both localities 
a material reduction in infestation has been noted. Special survey work 
started in the territory west of the Hudson River in 1936, was completed 
February 28, 1937. From July 1, 1936. to February 28, 1937, 488 towns and 
boroughs located in 31 counties were covered but no infestation was found. 
State and C. C. C. camp forces supervised by the New York Conservation 
Department located and treated several small isolated infestations in Columbia 
and Dutchess Counties within the barrier zone and in Westchester County, 
the Borough of the Bronx, and Nassau County to the south of the zone. Ex- 
cept for the infestations in Shawangunk and Putnam Valley above referred 
to, conditions are better in the State of New York than for several years.
