SERVICE AND REGULATORY ANNOUNCEMENTS 53 
In view of the fact that the Florida situation was not fully known and that 
there was a possibility of such cars containing infested products, it was apparent 
that cars loaded with Florida host fruits and vegetables unloaded at northern 
points and then placed uncleaned on loading tracks in peach-growing districts 
and other fruit-producing areas might result in the escape of the Mediterranean 
fruit fly in such areas and eventually in the general establishment of the pest 
throughout the United States. 
As the shipment of Florida host fruits and vegetables to the Southern and 
Western States was discontinued on May 16 under department order P. Q. C. A. 
No. 229 (which is printed in full on p. 101), the destinations involved in the car- 
cleaning requirements throughout the remainder of the spring shipping season 
were confined to the Northern and Central States. 
Between May 16 and June 30. 4.310 carload shipments of restricted material 
were reported as consigned from Florida to approximately 190 cities and towns 
scattered throughout such States. By June 30. car-cleaning reports had been 
received from the railroad companies covering 4,181 cars. 
In order to check on the efficiency of car cleaning, empty refrigerator and 
ventilated cars were inspected in transit at Potomac Yards, Cincinnati. Evans- 
ville. St. Louis, and Atlanta, and for briefer periods at Buffalo. Cleveland. 
Toledo, and Chicago. One hundred thirty-one cars which bore evidence that 
they had been used in the transportation of Florida products but had not been 
cleaned at the unloading point were intercepted between the middle of May 
and the end of the fiscal year. These were either cleaned at the point of in- 
terception or traced and cleaned later. The figure given is in addition to certain 
cars found dirty by railroad employees themselves and which were cleaned 
without reporting the individual number? of the cars concerned to the 
department. 
Supplemental to the Federal requirements, the officers of the States of 
Arizona and California insisted on the fumigation of all refrigerator cars en- 
tering their borders from eastern points, and under those requirements the 
largest of the refrigerator-car lines operating in the Southwestern States re- 
ports having fumigated 295 ears with hydrocyanic-acid gas during May. and 
1.174 during June. 
ROAD STATION OPERATION 
In order to prevent the movement of Florida host fruits and vegetables by 
truck and other road vehicles, a patrol service was established along the border 
between that State and Georga and Alabama. 
There were 22,727 cars inspected on the Georgia-Florida boundary during the 
period from May 16 to 31: of these 1.167 carried 1.442 lots of contraband fruits 
and vegetables. During June, 53.872 vehicles were inspected on this line, of 
which 2.319 carried 2.627 lots of contraband articles. 
On the Florida-Alabama line during June. 84,747 vehicles were inspected, of 
which 5.332 were found to be currying fruits and vegetables. 
PREVENTION OF SPREAD OF GIPSY MOTH 
During the S-montb period covered by this report the principal work con- 
cern! forest scouting in the barrier zone and in New Jersey to determine any 
points of infestation, together with the ereosoting of all egg masses found at 
any Buch points. In June, spraying begins in all districts which have been 
determined to be Infested by the preceding scenting work of fall and winter. 
As to New Jersey the outstanding feature was the finding of bnt a single 
point of Infestation during the fiscal year. This consisted of a number of 
egg clusters found in the western extreme of Piacataway Township in Middle- 
pel County. All of the egg clusters had hatched and small gipsy-moth larvae 
were found feeding on shrubbery and young fruit trees in the Immediate 
vicinity. The vegetation in and surrounding the area determined as infested 
was Sprayed during the period between May 10 and June 10 and was closely 
guarded to prevent th«' removal from the vicinity of any trees, shrubs, or por- 
tions thereof. 
Spraying work in the barrier-zone ana in western New England was started 
on June :: and finished shortly after the end of the month, infested localities 
were sprayed in the towns of Poultney, vt.. Bgremont, New Marlboro 
Sandlsfleld, Sheffield, and Tyringham, Mass.. and Canaan, Cornwall. Goshen, 
Norfolk. North Canaan, Salisbury. Wallingford. and Warren, Conn. An in-
