[July-Sept. 
Regulation 2. Shipments of 5-Leafed Pines 
section a. control of movement 
(1) Five-leafed pines shall not be moved or allowed to be moved interstate 
from an infected State or District to any point outside thereof, unless a Federal 
pine-shipping permit has been issued therefor and is attached to the outside of 
the container, except that, in the case of shipments to or between the States of 
Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, 
and Vermont, a control-area permit secured from the proper officer of the State 
of destination (see Appendix) may, until further notice, be substituted for the 
Federal pine-shipping permit. The pine-shipping permit may specify a desti- 
nation point or a limited destination area for the shipment, and in that event 
the pines covered thereby shall not be moved or allowed to be moved interstate 
directly or indirectly, either in the original container or otherwise, to destinations 
other than those authorized in such permit. 
(2) Five-leafed pines shall not be moved or allowed to be moved interstate 
from any State or District unless there is attached to the outside of the con- 
tainer thereof a valid State or District nursery inspection certificate of the State 
or District from which the shipment is made. 
(3) Branches and other parts of 5-leafed pines without roots may be shipped 
interstate from any State or District without restriction under these regulations, 
except that if such articles are visibly infected with the white-pine blister rust, 
they must either be shipped in a preservative or be authorized and labeled under 
the provisions of regulation 7. 
SECTION B. CONDITIONS GOVERNING THE ISSUANCE OF PERMITS 
(4) Federal pine-shipping permits may be issued upon compliance with the 
following conditions: 
(a) That the 5-leafed pines to be moved shall be grown from seed in a location 
within 1 mile of which there have existed since the time of planting said seed 
no European black currant plants and within at least 1,500 feet of which there 
have existed since the time of planting said seed no currant or gooseberry plants 
of any size or variety which in the judgment of the inspector would involve risk 
of spread of the white-pine blister rust. A Ribes-free zone greater than 1,500 
feet in width may be required when necessary in the judgment of the inspector 
to insure freedom from infection. The requirement that the Ribes-free conditions 
described must have been maintained since the time of planting the seed may be 
waived pending the completion of Ribes-eradication in the environs of the 
nursery, in the case of premises which, on account of their great distances from 
known points of blister-rust infection and the relative scarcity of susceptible 
Ribes in the vicinity of the 5-leafed pine stock, represent in the judgment of 
the Bureau of Plant Quarantine little or no risk of being involved in blister-rust 
infection. 
(6) That the owner of the nursery shall submit a signed application for a pine- 
shipping permit to the Bureau of Plant Quarantine, giving the location of the 
premises upon which said pines will be grown and agreeing that no 5-leafed pines 
shall be grown in or distributed by any nursery or nurseries owned or controlled 
by the applicant except such as are maintained in compliance with the previous 
paragraph: Provided, That in the case of nursery properties under single owner- 
ship and management but represented by units widely separate, such units may 
be considered as independent nurseries and pine-shipping permits may be issued 
for one or more such individual units based on the certification requirements 
stated below when in the judgment of the inspector no risk of spread of white-pine 
blister rust is involved. The application required herein should preferably be 
filed before the seed are planted (in order to avoid disappointment and loss in case 
the premises are later found not to comply fully with the requirements of para- 
graph (a) above). 
(c) That before shipment of said pines certification shall be made to the 
Bureau of Plant Quarantine by an inspector showing that the nursery stock 
has been found to be free from white-pine blister rust and that the premises 
and the environs have been inspected annually and maintained as specified in 
paragraph (a) above. 
(d) Permits for the reshipment of such pines certified under the conditions 
prescribed by paragraph (c) above may be issued to purchasers of such stock 
who do not grow 5-leafed pines upon receipt of an application and a signed 
agreement by the applicant agreeing to observe these regulations and the condi- 
tions under which the permit is issued.
