WORK IN PENNSYLVANIA 
With the Federal and State funds available in the Pennsylvania area and 
the assistance from Luzerne and Lackawanna Counties previously refera 
it was found possible to BCOUt intensively flood areas within the infested terri- 
tory along the Susquehanna and Lackawanna Rivers, assembling-cage sites 
where male ninths were captured last summer, sites of previously ! 
Infestations in outside territoryt and to do considerable scouting and creosoting 
in the generally infested area. Woodland areas were thinned and the >lash 
was burned in sections where effective scouting could not otherwise be done, 
sprouts were removed from stumps in territory previously em ever, and the 
most dangerous areas were sprayed during May and June. Burlap hands- 
also applied in woodland and residential sections where considerable 
Infestation exists. These burlaps were patrolled and all caterpillars found 
were destroyed. 
In a total of 70 infestations found during the fiscal year 1934 in 15 lightly 
infested townships, only 10 were reinvested in 1935, and 5 of these were in 
localities where only single egg clusters were found during 1934 and where no 
sj naying was done. In the other 5 the trees along the property lines were 
not sprayed because wind drift would have caused the spray to lodge in 
adjoining property not covered by permits. 
I niring the year 8.608 shipments of quarantined forest products, nursery 
stock, and other materials were inspected and a total of 70 gypsy moth egg 
Clusters were found and treated. There were a few quarantine volations, and 
in each of the cases prosecuted by the State the defendants were found guilty. 
SPECIAL SCOUTING 
From the latter part of January to the last of April, special survey work 
was carried on with negative results west of the Hudson River in the extreme 
southeastern part of New York, in northeastern Pennsylvania adjacent to the 
New York and New Jersey State lines and the area where regular scouting work 
has been performed, in sections of northeastern and southern New Jersey where 
no scouting or cage work had previously been done, in New Castle County, 
Del., and in three townships in Cecil County, Md. The State authorities in 
these States and in Ohio were urged to do as much special survey work as 
time and funds would permit in territory where Federal work was no: planned. 
Fifteen Federal experts w T ere detailed to this work. They paid particular atten- 
tion to trees and nursery plantings on large estates, around hotels, gasoline 
stations, cemeteries, and dumps; also in localities where large movable equip- 
ment used in construction work might have been used or stored. Although an 
average of not more than 4 days was spent in each town, the work was sutli- 
Ciently well done so that it is believed any sizable infestation would have been 
noticed. The State of New 7 Jersey furnished an Inspector who worked with 
the Federal employee assigned to duty in that State. Pennsylvania and Ohio 
also did considerable work of this type. No Infestation was found in any of 
the outlying territory. 
SPRAYING 
During the spraying season more 1 than 7.7(H» acres of woodland and 6,90 ' 
residential properties were treated in the Pennsylvania territory, and the other 
areas are indicated under the States concerned. This involved the use of C»l 
high-power spraying machines in the following states: Massachusetts, 11; Con- 
nectiCUt, 12; Pennsylvania, 27: New Jersey, 2. In addition to those. \) sprayers 
were loaned to the conservation department of the State of New York tor 
treating infestations on Long Island, in the BrOUZ, and in Austerlitx and Milan 
in the hairier zone. 
The weather during the spraying season was not so favorable as usual and 
Considerable time was lost on account of rain and wet foliage. 
\ embling-cage work was conducted in Vermont, Massachusetts, Connecti- 
cut, and Pennsylvania. 
DEFOLIATION EN NEW ENGLAND 
in the summer of 1984 defoliation caused by the gypsy moth was considerably 
in excess of that recorded for Im:;:'.. For the entire infested area a total of 
t woodland with from Blight to complete defoliation were found. 
as compared with .''.!»7.7:*.o acres recorded for 1933. in general there was less
