nation of pests in these shipments was given to 175,517 plants, 1,509 
lots of seeds, and 141 parcels containing plant material not for propaga- 
tion. Id addition 25,978 containers were examined at the post offices, 
express offices, and freight stations, and 19 truckloads containing 68,922 
plants consigned to retail merchants in the District of Columbia were

INSPECTION OF PLANT-INTRODUCTION AND PROPAGATING GARDENS 
Plant material that is being propagated at plant-introduction and 
propagating gardens maintained by the Bureau of Plant Industry, 
Soils, and Agricultural Engineering is inspected regularly for the 
presence of plant pests. Such material distributed from the gardens 
at Coconut Grove, Fla., and Mandan, X. Dak., was in-pected by State 
officials cooperating with this Bureau. The inspections at Chico, 
Calif., were handled jointly by an inspector from this Bureau and 
an entomologist from the California Department of Agriculture. 
Material distributed from the District of Columbia. Maryland, and 
Savannah, Ga., stations was examined by Bureau inspectors. The 
following were examined prior to distribution from these stations 
during 1944: 448,178 plants, 1,264 bud sticks and cuttings, 43,388 
roots and tubers, and 136 shipments of seeds. 
INTERCEPTIONS OF PROHIBITED AND RESTRICTED PLANTS AND PLANT PRODUCTS

in mail, 1,484 ; in quarters, 6,176; in stores, 3,558; total, 57.951. In 
addition, interceptions were made in baggage by customs officers at 
Mexican border ports where no plant-quarantine inspectors are sta- 
tioned. Customs officers at Canadian border ports without plant- 
quarantine inspectors made 210 interceptions.

operal ion Of the customs personnel in the enforcement of foreign plant 
quarantines, particularly at ports where traffic conditions do not now 
warrant the services of a plant-quarantine inspector. This is an impor- 
tant factor in maintaining the safeguards against pest entry.
