Currant and gooseberry plants shipped from any infected State or District 
must be either dormant and defoliated or else dipped in lime-sulphur solution 
(4.5° B.) immediately before shipment. (See regulation 3-&.) 
The control-area provision is continued and is extended to Maryland, Ohio, 
Pennsylvania, and Wisconsin. Under that requirement a control-area permit 
must be secured from the State of destination for the shipment of currant and 
gooseberry plants into those States which have legally establishd areas in 
which the growing of currant and gooseberry plants is prohibited. Such 
States are Connecticut, Idaho, Maine, Maryland, Massachusetts, Michigan, 
Minnesota, New Hampshire, New York, Ohio, Pennsylvania, Rhode Island, Ver- 
mont, and Wisconsin. (See regulation 3-c.)

NOTICE OF QUARANTINE NO. 63 
(Approved Aug. 27, 1926 ; effective Oct. 1, 192G ; supersedes Quarantine No. 26, as 
amended, and Quarantine No. 54, as extended) 
I, C. F. Marvin, Acting Secretary of Agriculture, have determined that it 
is necessary to quarantine every State of the continental United States and 
the District of Columbia, in order to prevent the spread of the white-pine 
blister rust (Cronartium ribieola Fischer), a dangerous plant disease not here- 
tofore widely prevalent or distributed within and throughout the United States. 
Now, therefore, under authority conferred by the Plant Quarantine Act of 
August 20, 1912 (37 Stat. 315), as amended by the act of Congress approved 
March 4, 1917 (39 Stat. 1134, 1165), and having duly given the public hearing 
required thereby, I do quarantine every State in the continental United States 
and the District of Columbia, effective on and after October 1, 1926. Here- 
after, under the authority of said act of August 20, 1912, amended as aforesaid, 
no five-leaved pines (Pinus) or currant and gooseberry plants (Ribes and 
Grossularia, including cultivated or wild or ornamental sorts) shall be moved 
or allowed to be moved from any such State or from the District of Columbia 
into or through any other State in the continental United States or the District 
of Columbia, except in manner or method or under conditions prescribed in 
the rules and regulations supplemental hereto and in amendments thereof: 
Provided, That the restrictions of this quarantine and the rules and regula- 
tions supplemental hereto may be limited to the areas in a quarantined State 
now or hereafter designated by the Secretary of Agriculture as infected when 
said State shall have provided for and enforced such control measures with 
respect to such designated areas as, in the judgment of the Secretary of Agricul- 
ture, shall be deemed adequate to effect the control and prevent the spread 
of the white-pine blister rust : Provided further, That, for the enforcement 
of the restrictions under this quarantine on the interstate movement of five- 
leaved pines and currant and gooseberry plants, all interstate shipments of 
nursery stock or other plants shall be subject to inspection at place of shipment 
or destination or at any point en route, by duly authorized 
inspectors of the United States Department of Agriculture. 
Done at the city of Washington this 27th day of August 1926. 
Witness my hand and the seal of the United States Depart- 
ment of Agriculture. 
C. F. Marvin, 
Acting Secretary of Agriculture.
