IMPORTATION OF NURSERY STOCK AND OTHER PLANTS FOR PROPAGATION ONLY. 



As already noted, provision is made in Quarantine 37 for the en try- 

 under special permit of limited quantities of otherwise prohibited 

 nursery stock and other plants for the purpose of keeping the country 

 supplied with new varieties and necessary propagating stock. The 

 question of availibility of plant material for which special permits 

 are requested is passed upon by a committee of specialists of the 

 Bureau of Plant Industry. The issuance of such permits is then 

 based on the recommendations of this committee. 



Three hundred and eleven special permits were issued during the 

 period from June 1, 1919, the date on which Quarantine 37 became 

 effective, to June 30, 1920, a period of 13 months. These permits 

 included a wide range of plant materials and are each issued for a 

 specific importation of plants. The importations authorized have 

 already been made in the case of approximately 174 of these permits. 

 The other permits have been canceled for a number of reasons, as a 

 general rule because of the inability of the grower to secure the 

 desired stock or because of transportation difficulties abroad and 

 other similar hindrances. 



The material thus imported was found as a whole fairly free from 

 dangerous insects or fungus diseases. It was, however, necessary 

 to destroy several shipments because of the presence of injurious 

 insects which could not have been eliminated by any kno\\'n treat- 

 ment. In spite of the fact that emphasis has been made at all times 

 on the necessity of bringing in plant material free of sand, soil, or 

 earth about the roots, 12 shipments were found the roots of which 

 in whole or in part were embedded in soil. These shipments were 

 returned to country of origin or destroved. 



A large number of special permits nave been issued also for the 

 fiscal year ending June 30, 1921. The record of these permits is not 

 inrhidod in tlie following tables, which give the classes of plants 

 actually imported up to June 30, 1920, country of origin, and the 

 States to wnich the imported plants were distributed. The actual
