LETTER OF TRANSMITTAL. 



U. S. Department of Agriculture, 



Division of Entomology, 

 Washington, D. C, Mary 7, 1903. 

 Sir: I have the honor to transmit herewith the manuscript of a 

 bulletin on The Control of the Codling Moth. This has been prepared 

 in a condensed form by Mr. C. B. Simpson, a special agent of this office, 

 from the extensive notes which he has taken during three years' inves- 

 tigation of the codling moth in the Northwest. On account of its 

 probable value to apple growers 1 recommend that it be published as 

 a Farmers' Bulletin. 

 Respectfully, 



L. O. Howard, Entomologist, 

 Hon. James Wilson, 



Secretary of Agriculture.
