BUREAU OF ENTOMOLOGY AND PLANT QUARANTINE 29 
victed of violating the State quarantine law. Approximately 32,500 
shipments originating within the generally infested area were thor- 
oughly inspected and certified as free from this insect before move- 
ment was permitted, and about 42,000 shipments originating in the 
lightly infested area were moved under permit during the year. 
GYPSY MOTH WORK BY CIVILIAN CONSERVATION CORPS 
This Bureau has continued to supervise C. C. C. gypsy moth work 
in part of the area between the barrier zone and the Connecticut 
River in Vermont, Massachusetts, and Connecticut, and cooperation 
has been maintained with the various State, Federal, and C. C. C. 
officials. 
After the hurricane of September 1938 the daily average of en- 
rollees available for the work dropped from 499, which was approxi- 
mately the same as at the end of the previous year, to 169. This 
amounted in man-days for the year to a reduction of 56 percent. 
At the beginning of the year men were available from 11 camps 
(2 in Vermont, 4 in Massachusetts, and 5 in Connecticut), while at 
the close of the year they were furnished by only 4 camps (2 in 
Massachusetts and 2 in Connecticut). All work was discontinued in 
Vermont soon after the storm, and the reduction in Massachusetts 
was very severe, as 2 of the camps removed worked exclusively on 
gypsy moth control. 
The drastic reduction in manpower made it impossible to approach 
the completion of the work plan. Scouting and burlapping were 
drastically cut, and the men were concentrated in areas of especially 
heavy infestation. Many areas that needed follow-up work were left 
untouched. If the work could have continued, as planned, further 
work in some areas could have been discontinued for several years. 
The severest and most extensive defoliation that has ever occurred 
in the area between the barrier zone and the Connecticut River in 
Vermont, Massachusetts, and Connecticut developed in the summer 
of 1938. Work was planned in these and adjoining areas during the 
present year but could not be carried out because the force was 
reduced. 
Some work was done in 38 towns (6 in Vermont, 12 in Massachu- 
setts, and 20 in Connecticut), and some infestation was found in all 
with the exception of 2 in Connecticut. As much of these areas as 
possible was treated. 
Approximately 62,000 6-hour C. C. C. man-days were used. Most 
of the work was done in very heavy infestation, so that slightly more 
than 25,000 acres were covered. About 1,650 acres of woodland were 
thinned, and approximately all the brush from this operation was 
burned. Over 8,800,000 new gypsy moth e^ clusters were destroyed, 
about 1,600,000 of which were burned in brush piles. In addition, 
burlap bands were applied to over 52,000 trees, and more than 3,400,- 
000 gypsy moth caterpillars and pupae were destroyed. 
Intensive work was done on 515 acres in the main infestation of a 
large woodland block in the Granbv-Simsburv-Canton section of 
Connecticut. On this acreage over 7,< '68,000 new gypsy I Loth egg 
clusters were destroyed by creosoting and burning. The work con- 
sisted of piling the foresl debris and of chopping oul much of the 
undergrowth, especially of the favored-food-plant species. This ma-
