310. Quarantine measures. — For a period of years it had 

 become evident that some measure should be taken to stop 

 the introduction of foreign disease and insect pests which 

 were annually finding their way to this country on nursery 

 stock and other plants and plant products. As a result, a 

 Plant Quarantine Act was passed by Congress on August 20, 

 1912, under authority of which the United States Depart- 

 ment of Agriculture has, from time to time, issued various 

 quarantine rulings which restricted or prohibited the im- 

 portation of certain plants and plant products found to 

 be infested with noxious diseases and insects. The ruling 

 which particularly affected the nursery and florist business, 

 and which was strongly protested by special interests, was 

 known as Quarantine 37, and was issued November 18, 1918. 

 This measure, together with later interpretations and rulings 

 thereon, provides that: 



"Stocks, cuttings, cions, and buds of fruits for propaga- 

 tion" and "seeds of fruit, . . . may be imported from coun- 

 tries which maintain inspection, under permit upon com- 

 pliance with these regulations, but, where a particular 

 purpose is specified, for that purpose and no other. . . . Im- 

 portations of nursery stock and other plants and seeds speci- 

 fied in this regulation, from countries not maintaining in- 

 spection, may be made under permit upon compliance with 

 these regulations in limited quantities for experimental pur- 

 poses only, but this limitation shall not apply to tree seeds." ^ 



From this ruling it will be seen that fruit-stocks for prop- 

 agating purposes are still admitted into the United States, 

 but possibly the time may come when all such stocks must 

 be grown here. 



311. Importations of stock. — While no restriction was 

 placed on the entiy of fruit-stocks, the impression went out
