thousands of individuals who might wish to make their own 

 importations would be small justification for the risk of 

 carriage of new pests to every part of the United States— a 

 risk which would he vastly greater than before Quarantine 

 37 was established. 



This situation led to the exclusion of importations 

 for mere personal use or gratification, and to the limitation 

 of the issuance of special permits for the entry of new or 

 unavailable plants chiefly to plant propagators who will agree 

 to utilize the plants imported for the purpose of reproducing 

 additional stocks for a period of one to five years, based on 

 the time needed for such multiplication or reproduction. The 

 immediate sale of plants thus imported is not permitted, but 

 no restrictions are placed on the sale of the plants produced 

 from the imported stock except that the importer will be ex- 

 pected to maintain a sufficient supply to meet his future needs. 



It is expected, therefore, that importations under Regu- 

 lation 14 will be largely by persons who will propagate the 

 imported stock as a commercial enterprise and thus perform a 

 public i ser vi c e by making such plants generally available. The 

 o#2.y exceptions are the issuance of pe units to provide for the 

 needs of botanic, gardens, agricultural colleges, experiment 

 stations, and other similar public institutions, and to those 

 few amateurs who are widely or nationally known as maintaining 

 collections of real merit and open to the public, or engaged in 

 work of public benefit with the plants concerned. If such 

 persons are not known to the experts of this Department, they 

 will be required to furnish evidence of their status. 



In the event, however, that the authorized agencies, 

 commercial or other, do not bring in varieties of plants which 

 enthusiastic plant lovers may wish, the Department has made 

 special provision for the entry through its Office of Plant 

 Introduction of any neglected or overlooked new varieties and, 

 incidentally, this Office has been undoubtedly the principal 

 agency for the importation of new plants into the United States 

 for the last twenty years. 



To recapitulate, the existing provisions for the entry 

 of new or unavailable plants under Regulation 14 include (1) 

 all the importations which any commercial grower is willing to 

 make, and such commercial growers include persons of world-wide 

 recognition as plant specialists and breeders; (2) importations 

 by botanic gardens and some hundred experiment stations and 

 Other public institutions with enthusiastic experts in horticul- 

 ture and floriculture; (3) importations by the leading and 

 recognized amateurs of the country, and (4) importations through 

 the Office of Foreign Seed and Plant Introduction of the Depart- 

 ment of Agriculture. 



Under the plan, therefore, of Quarantine 57, it becomes
