THE NEW FRENCH EXPORT PLANT INSPECTION SERVICE 



By L. O. Howard 



On page 76 of the current volume of the Journal of Economic 

 Entomology (February, 1910) occurs an abstract of remarks made 

 by the "WTiter on the subject of European conditions as affecting 

 nursery stock, in which it was shown that the French government 

 had promised to estabhsh a governmental inspection service in France, 

 under the Ministry of Agriculture. These remarks were made at 

 the Eighth Annual Meeting of Horticultural Inspectors at Boston, 

 on December 26, 1909. 



Early in November there was received at the Department of Agri- 

 culture through the French Ambassador to the United States and 

 the U. S. Department of State, a statement to the effect that the 

 service had been established, and transmitting more or less detailed 

 information from the official journal of the French Repubhc. Infor- 

 mation was conveyed that Dr. Paul Marchal, director of the Agri- 

 cultural Entomological Station at Paris, had been placed in charge 

 of the work, and the hope was expressed that the service established 

 would be satisfactory to the government of the United States, on the 

 understanding that the arrangement will not affect the right of the 

 United States to examine shipments of living plants, where necessary.
