28 ANNUAL BEPOBTS OF DEPARTMENT OF aGBIOULTUBE, 1935 
were cut and destroyed. Most of these were cut under the Emergency Relief 
Administration brown-tall-moth-removal project A few were cot by men 
from civilian Conservation Corps camps and a few more by the State ento- 
mologist In Massachusetts a Large proportion of the towns within the In- 
fested area wore examined for webs and 169,352 were cut and d< The 
winter was considered unfavorable for insecl survival and these records it di- 
cate that persistent treatment will be necessary to keep this I 
dangerous level. 
GYPSY MOTH QUARANTINE ENFORCEMENT AND CERTIFICATION 
REGULATORY CHANGES 
Revised quarantine regulations were promulgated to become eff< I I 
2, 1934. This involved the first change in the gypsy moth Infested ureas since 
1931. <)n the basis of freedom from infestation as evidenced by the Inspection 
of millions of Christmas trees over a period of years, supplemented by observa- 
tions Of district inspectors continuously stationed in the affected areas, it was 
possible to remove from the lightly Infested territory in Vermont certain towns 
adjacent to the Canadian border and along the northwestern periphery of the 
infested zone. On the other hand, a number of towns in the lightly bi- 
sections of Maine, New Hampshire, Vermont, and Connecticut were changed to 
heavily infested. This enlargement of the heavily Infested section added a 
strip of territory from 1 to 3 tiers of towns wide on the northern boundary 
of the former area. Conditions of gypsy moth infestation In the affected towns 
were determined by special scouts of the gypsy moth quarantine unit and by 
Civilian Conservation Corps workers employed under the supervision of State 
officials. The finds were sufficient to justify these towns being considered 
heavily rather than lightly infested. The principal effect of this change in the 
administration of the quarantine is the embargoing of the movement of Christ- 
mas trees from these latter areas in which the trees formerly were eligible 
for certification after inspection. There were also a few minor changes in 
products affected by the certification requirements. 
CERTIFICATION OF QUARANTINED PRODUCTS 
Routine demands for inspection and certification were met by a force of 
21 inspectors. Each Inspector was assigned to a district and was held responsi- 
ble for all details of quarantine enforcement in his district. When Japanese 
beet Le and gypsy moth certification was required, this joint Inspection & 
also was provided by the district inspectors. 
Quarries and nurseries in sections of the lightly infested area in which 
gypsy moth infestation had not previously been found were scouted for egg 
Clusters. The nurseries concerned had previously been scouted and found 
free from the Japanese beetle. Determination of freedom from gypsy moth 
infestation of these establishments and their surroundings allowed them to 
receive permits for their shipments without detailed inspection of each article. 
Christmas-tree inspection was performed from mid-November until December 
15. Mild weather during much Of this period facilitated examination of the 
tree-. At the peak of the Inspection early In December, 00 temporary in- 
spectors were employed. During the 1!»."> I shipping season there were certified 
377 carloads of trees. Tn addition, 206 carloads were shipped from the 41 
Vermont towns released from quarantine In October. This total of 583 can 
shipped from the areas as previously regulated is compared with a total of 
450 carloads certified therefrom in 1933. As the Inspected trees all originated 
in the Lightly infested area, only a single gypsy moth egg Cluster was found. 
Presence during the fall of large numbers of gypsy moth egg clusters on laurel 
ted to a change In the procedure whereby this commodity was certified. 
Lanrei branches In large quantities or after processing Into roping, wreaths, or 
funeral pieces cannot be satisfactorily inspected. Therefore, actual Inspection 
was limited to loose branches In small quantities. The bulk of this material 
was Inspected on the lot basis, in this manner, entire aninfested sections 
within which it was safe to pick laurel were designated after thorough scout- 
ing of the localities. Shippers desiring to manufacture decorative articles 
containing laurel for movement under certification were given certificates for 
material obtained from these aninfested sections. 
Prom early in October until the first week in December, Inspections were 
made of 161 lots from which evergreen boughs were gathered for shipment
