1933] SERVICE AND REGULATORY ANNOUNCEMENTS 203 
that the effectiveness of this treatment is greatly increased if bulbs which have 
been dried for mure than 3 weeks are presoaked in cold water for 2 hours, 
the use of this desirable modification of the treatment is recommended. The 
use of a disinfectant to check subsequent infections of diseases such as basal 
rot is optional with the permittee. The disinfectant may be used either in 
the hot water or as an after-dip. 
Further information regarding the treatments will be furnished upon request. 
Shipments requiring treatment shall be held intact at the place of treatment 
until the Bureau's representative arrives. In the event infestation is not 
general but occurs in only one or more clearly distinguishable units, only those 
infested units shall be required to be treated. All bulbs of the same variety 
from one shipper to the same addressee will be considered as belonging to the 
same unit unless evidence is presented to show that certain cases of the lot 
came from a separate source in the country of origin and unless such cases 
are marked to indicate that fact. When 2 or more varieties are included 
in the same case, the entire case will be considered as 1 unit unless these 
varieties are completely separated from each other in tight containers which 
would prevent an intermingling of dirt and debris. 
To prevent any unnecessary delay should treatment be required, the per- 
mittees should arrange in advance for facilities for giving any necessary 
treatments. Small lots of bulbs may be treated at the Inspection House of 
this Department in Washington, D.C. 
A permittee may elect to refuse a shipment if found infested, in place of 
providing for the required treatment. If any permittee intends to follow that 
plan, he should notify this Bureau in advance of the arrival of the bulbs, 
stating whether such infested shipment is to be removed from the country at 
his expense or is to be abandoned for destruction.

STRONG CALLS CONFERENCE ON IMPORTANT PLANT QUARANTINE 
> (Press notice) 
August 22, 1933. 
Called to " reexamine the underlying principles involved in the interpreta- 
tion and enforcement" of the Nursery Stock, Plant, and Seed Quarantine No. 
37, a public conference will be held at 10 a.m. October 25 by the Bureau of 
Plant Quarantine, United States Department of Agriculture. In announcing 
the conference, Lee A. Strong, Chief of the Bureau, referred to his statement 
issued July 20 in which he reviewed the legislative and administrative history 
of this quarantine, and indicated that the Department now is ready to give 
serious consideration to modification and liberalization of this regulation. 
The conference will meet in the auditorium of the Interior Department Building 
in Washington. 
In his statement a month ago Mr. Strong said: "After a careful and 
extended study of this whole problem, I find myself seriously questioning the 
need for, and the justice of, the procedure we are following. Inspection 
methods have been greatly improved and our scientific knowledge of foreign 
pests and diseases has increased. I feel that greater confidence can be placed 
in the efficacy of inspection of plant material at the time of arrival." In the 
formal announcement of the conference Mr. Strong threw open the door for 
discussion of all questions pertaining to this quarantine and mentioned specific 
subjects for consideration.
