268 BUREAU OF PLANT QUARANTINE [Oct.-Dec. 
rial will not pass through any cotton-growing territory outside the areas regu- 
lated under this quarantine or the Federal quarantine on account of the 
Thurberia weevil; samples (except when moved as ahove 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 carry- 
ing 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 
areas on such conditions as may be prescribed by that Bureau. 
Regulation 9. Linters and Samples 
Linters and samples thereof shall not be moved or allowed to be moved 
interstate from a regulated area unless a permit shall have been issued there- 
for by the United States Department of Agriculture. 
Permits may be issued for the interstate movement of linters or samples 
thereof, produced in a regulated area, on condition that said linters were pro- 
duced from sterilized seed and protected from contamination to the satisfaction 
of the inspector, and on compliance with the following additional requirements 
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 linters produced in a heavily infested area (regardless of destination) 
must be either fumigated under vacuum or roller treated, or given such other 
treatment as may later be approved by the said Bureau ; baled linters produced 
in a lightly infested area to be shipped 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 linters and 
samples thereof produced in a lightly infested area may be shipped interstate 
under permit to another regulated area 6 without fumigation or other treatment 
on condition that the material will not pass through any cotton-growing ter- 
ritory 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 infested 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 linters 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 such 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 imprac- 
ticable owing to the lack of satisfactory facilities or for some other sound 
reason, permits may be issued for the interstate movement of linters from the 
regulated areas on such conditions as may be prescribed by that Bureau. 
Regulation 10. Mill Waste, Unbaled Lint and Linters, and Other Forms 
of Unmanufactured Lint and Linters 
No form of cotton lint, linters, or fiber shall be moved or allowed to be 
moved interstate from a regulated area unless a permit shall have been issued 
therefor by the United States Department of Agriculture, except that no permit 
is required for the interstate transportation of materials which have been woven 
or spun from cotton lint or linters and are uncontaminated with other cotton 
or cotton products, nor for the interstate transportation of mattresses, pillows, 
cushions, or upholstery which have been commercially manufactured in com- 
pliance with the pink-bollworm regulations of the State concerned and in which 
any unwoven lint or linters used are completely enclosed in the finished 
product.
