 The Honorable Commissioner of Agriculture, 



Albany, N. Y. 



Sir: — This bulletin embraces the results of long investigation 

 and observation of the grape-vine flea-beetle and is submitted foi: 

 publication under Chapter 67 of the Laws of 1898. 



The difficulties of combating this pest of the vineyard have 

 heretofore appeared to be insurmountable. The life-history and 

 habits of the beetle have been discovered, and the results of 

 numerous experiments indicate that it is not more difficult to 

 destroy than many other pests. 



The bulletin certainly emphasizes the need of being alert and 

 observing. The mistake in the past seems to have been that 

 the enem}^ was allowed to do its w^ork before an effort was made 

 to destroy it. 



This bulletin will commend itself, we believe, to the grape- 

 growers of the country not only because of its completeness and 

 of the care which has been exercised in the work necessary to 

 secure the facts embodied in the publication, but because of its 

 practical value to the grape industry. 



I. P. Roberts, 



Director.
