464 REPORT OF THE COMMISSIONER OF AGRICULTURE. 



of tlie investigations, so far as they have been written np, will be pub- 

 lished directly under the new Division. 



In this connection, as evidence of the interest abroad in applied en- 

 tomolog"}', I would refer to the holding of an international exhibition 

 of machinery and contrivances for applied remedies against fungi and 

 insects that are destructive to cultivated plants. This congress was 

 held in October at Florence, and his Excellency, B. Grimaldi, the min- 

 ister of agriculture, industry, and commerce for Italy, was very anx- 

 ious to have the Division represented by such discoveries and mechan- 

 ical appliances as have been developed in its work of late years. He 

 was also very anxious to have a representative from the Department 

 to take part in the discnfesions of the congress to be held in connection 

 with the exhibition. The Entomologist was in fact made one of the 

 jurors, and it is to be regretted that, by the terms of our appropria- 

 tion, the Department was unable to have entomological representation 

 at said congress. From reports of the congress that have come to 

 hand, kindly furnished by Prof. Gustav Foex, in charge of the experi- 

 mental school of agriculture at Montpellier, and of Henri Grosjean, of 

 Paris, it is evident that they have made good use of the remedies and 

 contrivances published and recorded in our annual reports, and that, 

 with the exception of experience against the Grape-vine Phylloxera, 

 there was not very much that would have interested us in America. 



The work of the Division is best represented by its published re- 

 sults, as, after all, its value is proportioned to the manner in which it is 

 placed upon record and made available to the public, though there is 

 of necessity a great amount of work that is not accounted for in print. 

 In the matter of published and contemplated reports and bulletins, 

 the following list represents the activity of the Division fairly well:
