Recognition, however, should be given to the fact that the greater 
part of the importations handled in Washington, D. C, represented 
special-permit material and, as such, received very close inspection 
and frequently some sort of treatment as a condition of entry. 
The enforcement of the regulations governing the movement of 
plant material into and out of the District of Columbia required the 
inspection of 1,164 shipments of incoming domestic material (con- 
sisting of 326,895 plants, cuttings, bulbs, etc., and 3.026 lots of seeds). 
234 of which received some form of treatment for the elimination of 
pests; and 8.272 shipments of outgoing domestic material (consist- 
ing of 214,151 plants, cuttings, bulbs, etc., and 11,063 lots of seeds), 
404 of which required treatment. In addition, 10,009 containers of 
domestic plant material were inspected at the post office and at rail- 
way and express stations. Twenty-one and one-half carloads of 
plants included in these figures are designated as 21% containers. 
INSPECTION OF PLANT-INTRODUCTION AND PROPAGATING GARDENS 
Plant material which is being propagated at plant-introduction 
gardens maintained by the Bureau of Plant Industry is inspected at 
regular intervals for the presence of plant pests. Plant material 
distributed from the plant-introduction gardens at Coconut Grove. 
Fla., and Mandan, X. Dak., was inspected by State officials cooperat- 
ing with this Bureau. The inspections at the plant-introduction 
garden at Chico, Calif., were handled jointly by an inspector of this 
Bureau and an entomologist from the California State Department of 
Agriculture. Material distributed from the District of Columbia, 
Maryland, and Savannah. Ga.. was inspected by inspectors of the 
Bureau. A summary of these inspections appears in table 18.

INTERCEPTIONS OF PROHIBITED AND RESTRICTED PLANTS AND PLANT PRODUCTS 
The inspection of ships, airplanes, vehicles, cargo, baggage, ship's 
stores and quarters, and foreign mail packages at the various mari- 
time and border ports of entry resulted in the interception of large 
quantities of prohibited and restricted plant material. Much of this 
intercepted plain material was infested with insects or infected with 
plant diseases of considerable economic importance. In classifying 
the interceptions, those made at bridges and crossings at tin' Mexican 
and Canadian border ports have been considered as having been 
taken from baggage A record of the number of interceptions of 
prohibited and restricted plant material appears in table 19.
