208 BUREAU OF PLANT QUARANTINE [July-Sept. 
Permits may also be issued for the interstate movement of sterilized seed 
produced in a lightly infested area to an authorized oil mill in nonregulated 
territory for crushing; as one of the conditions for such authorization, oil 
mills in nonregulated territory must agree to maintain such safeguards against 
the spread of infestation, and to comply with such restrictions on the subse- 
quent movement of the linters and other products manufactured from the seed 
concerned as may he required by the Bureau of Plant Quarantine. 
Permits may be issued for the interstate movement of seed from lightly in- 
fested areas to any destination on condition that it has been given a special heat 
treatment at 145° P. maintained under approved conditions for a period of at 
Least 1 hour and subsequently has been protected from contamination, or has 
been given such other treatment as may later be approved by the Bureau of 
Plant Quarantine. 
In cases where, in the judgment of the Bureau of Plant Quarantine, the 
carrying out of the treatments required in this regulation becomes impracticable 
owing to the lack of satisfactory facilities or for some other sound reason, per- 
mits may be issued for the interstate movement of cottonseed from lightly 
infested areas on such conditions as may be prescribed by that Bureau. 
COTTONSEED PRODUCED OUTSIDE THE REGULATED AREAS 
Cottonseed produced outside of but brought within a regulated area may be 
moved interstate from such area under permit on condition that while in the 
area the seed has been protected from contamination in a manner satisfactory 
to the inspector. 
Regulation 8. Lint and Samples 
Lint and samples thereof shall not be moved or allowed to be moved inter- 
state from a regulated area unless a permit shall have been issued therefor 
by the United States Department of Agriculture. 
Permits may be issued for the interstate movement of lint or samples thereof, 
produced in a regulated area, on condition that the said lint was produced in a 
gin operated, as to seed sterilization and the prevention of contamination, to the 
satisfaction of the inspector, and on compliance with the following additional re- 
quirements which shall be carried out under the supervision of an inspector and 
in manner and by method approved by the Bureau of Plant Quarantine : 
Baled lint produced in a heavily infested area (regardless of destination) 
must be given both vacuum fumigation and either compression or roller treat- 
ment, unless and until the said Bureau shall approve some other treatment or 
treatments for the purpose; baled lint produced in a lightly infested area to 
be moved to nonregulated territory must be either fumigated under vacuum, 
or compressed, or roller treated, or given such other treatment as may later be 
approved by the said Bureau; baled lint and samples thereof produced in a 
lightly infested area may be moved interstate under permit to another regu- 
lated area 4 without fumigation or other treatment on condition that the ma- 
terial will not pass through any cotton-growing territory outside the areas 
regulated under this quarantine or the Federal quarantine on account of the 
Thurberia weevil ; samples (except when moved as above from a lightly in- 
fested area to another regulated area), whether produced in a lightly infested 
or heavily infested area, must be either fumigated, inspected, or otherwise 
treated as may be required by the inspector. 
Permits may be issued for the interstate movement of baled lint or samples 
thereof grown outside of but brought within a regulated area and to be moved 
therefrom, on the furnishing of evidence satisfactory to the inspector that the 
said materials have been protected from contamination. 
In cases where, in the judgment of the Bureau of Plant Quarantine, the 
carrying out of the treatments required in this regulation becomes impracticable 
owing to the lack of satisfactory facilities or for some other sound reason, 
permits may be issued for the interstate movement of lint from the regulated 
on such conditions as may he prescribed by that Bureau.
