LETTER OF TRANSMITTAL. 



U. S. Department or Agriculture, 



Washington, D. C, Marcli 6, 1907. 



Sir: We have the honor to transmit herewith a paper entitled 

 "Insect and Fungous Enemies of the Grape East of the Rocky Moun- 

 tains," prepared by Mr. A. L. Quaintance, of the Bureau of Entomol- 

 ogy, and Dr. C! L. Shear, of the Bureau of Plant Industry. 



This bulletin treats of the principal insect and fungous enemies of 

 the American varieties of grapes, giving the most successful methods of 

 treatment at present known. It first states the nature of the insect 

 enemies and the means of controlling them, then discusses the fungous 

 parasites, including treatment, and in conclusion gives an account of 

 spraying apparatus, with directions for applying spray mixtures. 

 The reason for the joint publication arises from the fact that the reme- 

 dial measures used in combating the insects and the fungous parasites 

 are of such a nature that the applications can be combined and there- 

 by result in a great reduction in cost of time and labor. We recom- 

 mend the publication of this paper as a Farmers' Bulletin. 



Respectfully, 



L. O. Howard, 



OMefofthe Bureau of Entomology. 

 B. T. Galloway. 

 Chief of the Bureau of Plant Industry. 

 Hon. James Wilson, 



Secretary of Agriculture.
