think European authorities have very rarely quarantined against Amer- 

 ican fruits on the grounds of danger of introduction of injurious insects. 

 It is true that the German Empire and one or two other goverments 

 quarantined American apples on account of the San Jose scale. It is 

 my understanding, however, that in the case of Germany this quaran- 

 tine was not issued so much on account of the San Jose scale as to 

 favor growers of apples in that country. Personally, I do not believe 

 Europe will quarantine against the oriental fruit moth. 



Mr. T. J. Headlee: We do not want any misconception concern- 

 ing the measures that are taken to prevent the distribution of the Jap- 

 anese beetle on nursery stock into other parts of the United States. 

 From the time the existence of this insect was recognized no plants have 

 been allowed to leave the infested sections of the nursery with- 

 out having all the soil removed from the roots. In view of the fact 

 that the plants are moved when the Japanese beetle is in the ground as 

 a grub, such precautions would seem ample to prevent the distribution 

 of the insect on nursery stock. 



Mr. E. N. Cory: You don't attempt to control the action of the 

 individual in taking plants out of the areas? 



Mr. T. J. Headlee : In response to Mr. Cory's question, up to the 

 past season we have made no attempt to prevent individuals from 

 carrying in hand, bag or vehicle, individual plants such as rosebushes 

 from premises within the infested area. During the past season a cam- 

 paign of education was put on among the people living in the infested 

 district for the purpose of obtaining their cooperation in the prevention 

 of this sort of movement. During the coming year still greater and 

 we hope more effective efforts will be taken along this line.
