12 BULLETIN 81 7 U. S. DEPARTMENT OE AGRICULTURE. 



Pending the completion of arrangements with foreign governments 

 for the survey and delimitation of disease-free districts and for the 

 inauguration of a system of inspection and certification of potatoes, 

 a temporary quarantine was laid, as follows: 



United States Department of Agriculture, 



Office of the Secretary, 

 Federal Horticultural Board. 



Notice of Quarantine No. II (Foreign), 

 potato quarantine. 



The fact lias been determined by the Secretary of Agriculture that injurious potato 

 diseases, including the powdery scab {Spongospora subterranea), new to and not 

 heretofore widely prevalent or distributed within and throughout the United States, 

 exist in the Dominion of Canada, Newfoundland, the islands of St. Pierre and Mique- 

 lon, Great Britain, Ireland, and Continental Europe, and are coming to the United 

 States with imported potatoes. 



Now, therefore, I, David F. Houston, Secretary of Agriculture, under the authority 

 conferred by section 7 of the act of Congress approved August 20, 1912, known as 

 "The Plant Quarantine Act" (37 United States Statutes at Large, page 315), do hereby 

 declare that it is necessary, in order to prevent the introduction into the United 

 States of such potato diseases, to forbid the importation into the United States, from 

 the countries hereinbefore named, of the common or Irish potato {Solarium tuberosum) 

 until such time as it shall have been ascertained, to the satisfaction of the Secretary 

 of Agriculture, that the country or locality from which potatoes are offered for import 

 is free from such potato diseases. 



On and after December 24, 1913, and until further notice, by virtue of said section 

 7 of the act of Congress approved August 20, 1912, the importation, from the countries 

 hereinbefore named, of the common or Irish potato, except for experimental or scien- 

 tific purposes by the Department of Agriculture, is prohibited: Provided, That ship- 

 ments of such potatoes loaded prior to December 24, 1913, as shown by consular in- 

 voices, will be permitted entry up to and including January 15, 1914. 



Done at Washington this 22d day of December, 1913. 



"Witness my hand and the seal of the United States Department of Agriculture.

Secretary of Agriculture. 



A GENERAL QUARANTINE NOW IN EFFECT. 



The order quoted above has resulted in the stoppage of potato 

 importations from Canada and all the countries of Europe for an 

 indefinite period. It is not known at present how many of these 

 countries will ultimately qualify for the lifting of the quarantine, but 

 the apparent general distribution of powdery scab in many of them 

 makes it improbable that they will resume shipments to the United 

 States in the near future. Certain portions of Canada are reported 

 to be nearly free from powdery scab, and the vigorous campaign now 

 being waged there against the disease offers hope that the restriction 

 may be modified with respect to specified districts at an early date. 



The initiative in lifting the quarantine rests with the foreign 

 government, which must notify the United States that specified dis-
