HADLEY: GREEN JAPANESE BEETLE 
199 
County, New Jersey. In addition to this territory, the intra-state 
quarantine order included the township of Palmyra and the Borough 
of Riverton in the area subject to quarantine. The regulations also 
provided for the thorough cleaning of all vehicles employed in the trans¬ 
portation of this product. The details of the rules and regulations of 
the state quarantine order were identical with those of the federal 
quarantine, already in force, and their enforcement delegated to the 
representative of the state already attached to the green Japanese 
beetle force. In effect, the representative of the Federal Horticultural 
Board was directly responsible for the enforcement of both quarantine 
orders without further distinction. 
In enforcing the quarantine regulations, the following methods of 
precedure were adopted. Early in the spring of 1919, a questionaire, 
together with a map of the infested territory on which the location of 
the farm could be indicated, and a copy of the regulations, were sent 
to every resident of the quarantined area who owned or rented five or 
more acres of land. In this way it was possible to determine what 
farms were growing sweet corn, what proportion was intended for 
home consumption and what for sale, where it was to be shipped, loca¬ 
tion and other data of importance in carrying out the provisions of the 
quarantine. 
This territory was roughly divided into three districts, (1) including 
those farms within the quarantined area, but well outside the known 
limits of infestation; (2) those farms within the probable limits of 
infestation, but not as yet actually infested; and (3) those farms 
known to be actually infested. 
For the first district, “blanket” certificates were issued to each 
farmer growing green or sweet corn for sale, allowing unrestricted ship¬ 
ment of their product up to August 15, or until revoked for cause. It 
was expected that the limits of a possible spread of the beetle would be 
known by that time, and after that date the certificates were extended 
for the balance of the season, except where circumstances did not war¬ 
rant such action for individual cases. 
For the second district, similar “blanket” certificates were issued, 
valid until July 25, or until revoked for cause. It was anticipated that 
by that time the outlying points of infestation would be definitely 
known. After that date, the certificates were extended if circum¬ 
stances warranted; otherwise the farm in question automatically fell, 
in the third classification. 
For the third district, comprising those farms known to be infested 
in greater or less abundance, no “blanket” certificates were issued, 
but actual inspection and certification of every package of corn was 
required before it could be moved from the farm. Throughout this
