14 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1934 
vania. The nursery area from which the soil samples were collected aggregates 
113.6 acres. Of this acreage, 39.6 acres required the addition of approximately 
6.5 tons of lead arsenate to bring the concentration up to the required dosage of 
1,500 pounds of the poison in the upper 3 inches of surface soil throughout the 
areas. Totals of 217 nursery plots, 227 frames, and 6 heeling-in plots were found 
to contain lead arsenate equaling or exceeding the required amount. The 
renewal of the lead arsenate concentration in all nursery plots containing growing 
plants was accomplished by the end of the fiscal year." On May 31 all chemical 
apparatus and reagents were transferred from the technological laboratory at 
White Horse, N. J., to the Japanese beetle research laboratory of the Bureau of 
Entomology at Moorestown. The State-owned White Horse laboratory was 
reconditioned for occupancy by the New Jersey Department of Agriculture. 
Instructions to Inspectors on the Treatment of Nursery Products, Fruits, 
Vegetables, and Soil, for the Japanese Beetle was issued on March 14, 1934, as 
B. P. Q.-359. This 17-page mimeographed circular replaces P. Q. C. A.-224, 
dated April 16, 1929, and 7 supplements issued later. These instructions now 
assemble in a single manual complete details of all types of treatments currently 
employed as a basis of quarantine certification under the regulations. 
CERTIFICATION OF FRUITS, VEGETABLES, AND CUT FLOWERS 
For the first time since 1923 it was possible to maintain a continuous 24-hour 
fruit and vegetable inspection service in the Philadelphia market district from 
June 15, the effective date of the seasonal quarantine on these commodities, until 
the restrictions were lifted. The fumigation of bananas loaded at wharves on 
the Philadelphia water front was also unnecessary. In the Philadelphia market 
and water-front districts where formerly there have been dense flights of the 
insect, the adults in 1933 were present in greatly reduced numbers. It was still 
possible to find beetles in fair quantities in these sections, but swarming did 
not occur. 
Advantageous prices in Chicago, St. Louis, Detroit, Indianapolis, Cleveland, 
and Cincinnati for string and lima beans grown in southern and central New 
Jersey and eastern Pennsylvania occasioned an unprecedented demand for the 
inspection and certification of these commodities. The midwestern drought of 
1933 and the large influx of visitors to the Century of Progress Exposition at 
Chicago probably created the great demand for eastern-grown beans. Speedy 
inspection of the large quantities of beans examined was accomplished through 
the use of 22 mechanical bean-inspecting machines. The largest number of beetles 
separated from a single consignment consisted of 430 specimens removed from a 
carload of 667 bushels of string beans consigned from Morrisville, Pa., to Chicago. 
During the height of the bean inspection there was a differential of $0.95 per 
bushel between the price obtained in the midwestern markets and that received 
on the New York market. Approximately 9,900 beetles were removed from the 
machine-inspected beans. 
Observations in sections from which quarantined fruits and vegetables were 
being certified showed that adult-beetle flight had, by the middle of September, 
subsided enough to justify the removal of the restrictions on these two items. 
Accordingly, the seasonal restrictions on the movement of fruits and vegetables 
were lifted, effective on and after September 15. Restrictions on the movement 
of cut flowers were allowed to remain in effect until October 15. Inspectors in 
the Philadelphia wholesale cut-flower market found adult beetles in cut flowers as 
late as October 5. 
VEHICULAR INSPECTION 
Already established for approximately 3 months at the beginning of the fiscal 
year, 25 vehicular inspection stations continued in operation on the borders of the 
regulated territory in Virginia, and along the Maryland- West Virginia, Penn- 
sylvania-West Virginia, and Pennsylvania-Ohio State lines. A roving patrol of 
Pennsylvania inspectors continued to check traffic on exit highways leading into 
the nonregulated territory in the northwestern part of the State. The 4 State- 
employed inspectors comprising a mobile patrol on highways at the boundary of 
the regulated zone in northwestern New York continued their schedules on 10 roads 
until October 16. At the end of October the personnel at the remaining posts 
was reduced from 53 to 42 men. Ten of the remaining inspectors were relief 
workers, supplied through the Pennsylvania Emergency Relief organization. 
Closing of the remaining 31 stations was accomplished from November 9 to 15. 
Road patrol for 1934 was begun on March 27 with the establishment of two 
posts in Virginia. Additional stations were opened shortly thereafter. By the
