BUREAU OF PLANT QUARANTINE O 
In September, after the force had been assembled and trained, work was taken 
up along the Susquehanna and Lackawanna Rivers in order that any infestation 
that existed might be treated to prevent the movement of egg clusters on drift- 
wood during high water. The Susquehanna River banks were scouted from the 
Newport Township line north to the Falls Township line, a distance of approx- 
imately 25 miles, and the banks of the Lackawanna were scouted a distance of 
7 miles from its mouth northeastward. Only 5 small infestations were found as 
a result of this work, 3 in Pittston Township and 2 in the boroughs of Old Forge 
and Taylor. Prior to this time 1,823 assembling cages were put up in 54 towns 
surrounding the badly infested area and were patrolled by the field men. Sixty- 
one moths were taken from 31 of these cages. 
An effort was made in Pennsylvania to scout and treat the area known to be 
most heavily infested and to determine as far as possible the outlying infestations 
by scouting the roadsides, orchards, and trees along the woodland borders. This 
resulted in finding infestations in territory that had not been examined the 
previous year, and on March 1 the Pennsylvania State quarantine was extended 
to cover the area of 700 square miles known to be infested at that time. Since 
that date, scouting has been continued in the territory surrounding the infested 
area, particularly toward the north, east, and south, and several small isolated 
infestations have been located. This brings the acreage of territory that should 
be placed under quarantine up to 880 square miles. The scouting disclosed no 
outlying colonies beyond the generally infested area, and this indicates that the 
problem in Pennsylvania consists of the difficult task of wiping out the infestation 
in the large area described above. The work accomplished is listed in table 1. 
Twenty-one spraying machines were operated in this territory during the summer. 
Over 2,700 residential properties were treated, but most of the work was done 
in woodlands where long lines of hose and irregular terrain made progress slow and 
difficult. 
In the enforcement of the State quarantine, which was handled cooperatively 
with this office, 1,999 shipments were inspected and certified. Most of this 
material consisted of mine props and lagging, but nursery stock, and a miscel- 
laneous assortment of forest products, cable reels, etc., were also inspected before 
movement was permitted. 
On August 16, 1933, an allotment of $2,020,620 was made by the Public Works 
Administration to the Bureau for the purpose of carrying on the control and 
extermination work in Pennsylvania, in the barrier zone in New England and New 
York, and in the strip of territory between the barrier zone and the Connecticut 
River in Connecticut, Massachusetts, and Vermont. After this allotment had 
been made the funds carried in the regular appropriation for scouting and exter- 
mination were withdrawn and the gypsy moth force, with the exception of the 
quarantine section, was transferred to work under this allotment. The work 
was organized rapidly and men began reporting the first week in September. 
More than 2,000 men were employed through the offices of the national reem- 
ployment service in the States where the work was to be done. The force 
decreased somewhat during the winter, and in March and early April 1934 drastic 
reduction in personnel was necessary in order that $459,282 of the funds available 
could be carried over for use after July 1. The number of employees was 
decreased to approximately 450, but by the 1st of June it was necessary to 
employ additional men to take care of spraying, and the rolls for that month 
averaged 1,200 men. 
On June 30 the emergency work was discontinued and all temporary employees 
dropped, with the exception of a small force needed to care for and repair equip- 
ment and compile and complete the records of the project. 
Through a provision in the agricultural appropriation bill, $360,000 was made 
available to carry on the regular work of this project for the fiscal year 1935. 
In order to carry through the gypsy moth project on the increased funds 
available during the year, additional supplies of insecticides, tools, and other 
equipment were purchased. One hundred and sixty-five tons of arsenate of lead 
and 10,500 gallons of fish oil were purchased for the spraying work in the New 
England territory, and 80 tons of arsenate of lead and 3,500 g lllons of fish oil were 
purchased for the Pennsylvania area. Most of the supplies in Pennsylvania were 
procured by the State. It was also necessary to remodel most of the spraying 
equipment so that constant spraying could be maintained to prevent delay in 
filling the tanks, and 10 additional high-power spraying machines, mounted on 
light automobile chassis, were obtained.
