94 ANM AL ItKroliTS OF I ►KI'A IM MKNT OF AGUICULTUUE, 1937 
as tb(y aflct t tlie entry of for»'i;;ii i»laiits and plant piodiuis into the island. 
Insular inspeetors serving as collaltorators render valuable a.ssistanee, esi>ecially 
in that portion of the work pertaining to tlie enforcement of the foreign plant 
(juarant inos. 
Inspections are made in the fields, in packing liouses, and on the docks 
of such fruits and vegetables as are permitted to move to the mainland under 
ihe i)rovisions of quarantine No. 58. During the year 2,^17 shipments, con- 
sisting of oo bunches of bananas, 519,031 crates of pineapples, and 17,100,020 
pounds of other approved fruits and \'egetables were certified for such 
movement. 
InsiK'ction is also made of parcel-post packages originating on the island and 
destined for points in continental United States. Through cooperation with 
post-oflice officials, arrangements were made to carry on this inspection at 
the four main post offices on the island. This arrangement has increased con- 
siderably the elliciency of this phase of the work and has also greatly reduced 
the number of Puerto Kican mail packages requiring inspection upon arrival 
at New York. A total of 5.()5'> packages were examined in the San Juan office, 
and 337 were found to contain prohibited plant material and were returned to 
the sender. Inspection figures for the post offices in Mayaguez, Ponce, and 
Arecibo are not available. 
In Ilawaii the enforcement of foreign plant quarantines is handled wholly 
by in.sular inspectors serving as collaborators. The inspectors of this Bureau 
stationed in the Hawaiian Islands are engaged in the enforcement of quaran- 
tine No. 13, which governs the movement of fresh fruits and vegetables to 
the mainland. Inspections are made in the fields, packing houses, and on the 
docks of such fruits and vegetables as are permitted to move to the mainland 
under the provisions of quarantine No. 13. During the year, ].72*^ shipments, 
representing 71,1SI> bunches of bananas, 39,443 crates of pineapples, and 3.712.002 
pounds of other approved fruits and vegetables, were inspected and certified. 
It is necessary to devote considerable time to the inspection of parcel-post 
packages originating in Hawaii and destined for mainland points. During 
the year 102.r)64 such packages were opened and examined and the plant 
quarantine status of 163.8-14 packagers was determined by other means: 5C 
packages were found to contain prohibited plant material. 
Inspection and sealing of baggage of travelers between Hawaii and the main- 
land were continued. A total of 3,485 pieces of baggage were safeguarded in 
this manner. 
On November 1, 1936, the inspection and clearing of airplanes bound for 
mainland ports was inaugurated at the Pearl City airport and on April 10. 
1937, inspection of shipments of plant material from Hawaii to the mainland 
by air express was commenced. This inspection not only avoids delay upon 
the arrival of the airplanes at the mainland, but also is a decided advantage 
from the standpoint of pest risk. 
INSPECTION OF SPECIAL-PERMIT AND DEPARTMENTAL PLANT MATERIAL 
Importations of propagating plant material are inspected at special ports of 
entry designated for that purpose. Most of these special-permit importations 
:ire in.spected and treated at the inspection house at Washington, D. C. In 
addition to special-permit importations, departmental importations and plant 
I>ropag.!fing material distributed by the Department are likewise inspected at 
the Washington, D. C, inspwtion house. The inspection-house stafT at Wash- 
ington also inspects and certifies for interstate shipment commercial shipments 
of nur.sery stock, in order that such shipments may moot the certification 
requirements of the various States. Tabh^ 27 gives a summary of insi>ections 
unci treatments of nursery stock at the Washington, D. C, inspection house 
during th<^ year.
