LETTER OF TRANSMHTAL. 



United States Department of Agriculture, 



Washington, D. C, July 11, 1906. 

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

 Control of the Codling Moth and Apple Scab," by C. L. Marlatt, of 

 the Bureau of Entomology, and W. A. Orton, of the Bureau of Plant 

 Industry. 



This bulletin deals onl}^ with the two principal enemies of the apple, 

 namely, the chief insect enemy, the codling moth, and the principal 

 fungous disease, apple scab. The reason for such joint publication 

 arises from the fact that the remedial treatment for both of these is 

 of such a nature that the applications can be combined at a lessening 

 of nearly one-half the cost of time and labor. The bulletin includes 

 a brief but plain statement of the nature of the codling moth and the 

 means of controlling it, followed by a similar portion relating to 

 apple scab, and concluding with the combined directions for spraying, 

 and a spray calendar. We recommend the republication of this paper 

 as Farmers' Bulletin No. 247, revised, the original edition having 

 appeared March 7, 1906. 



Respectfully, L. O. Howard, 



Chief, Bureau of Entomology. 

 B. T. Galloway, 

 Chief, Bureau of Plant Industry. 

 Hon. James Wilson, 



Secretary of Agriculture.
