LETTER OF TRANSMITTAL. 



Raleigh, N. C, October 1, 1909. 



Sir: — I have the honor to transmit herewith manuscript for a 

 Bulletin on "Insect Enemies of Tobacco/' together with illustrations 

 for same. This is by Mr. Z. P. Metcalf, Assistant Entomologist, 

 and is designed to answer many of the questions concerning tobacco 

 insects that come to this office every year. 



This Bulletin is based not only on the correspondence of the 

 office and a careful study of the literature on the subject, but also 

 includes the results of a number of original observations and experi- 

 ments by Mr. Metcalf during the past two seasons, most of which 

 were made in Granville County. I recommend that it be issued as 

 a Bulletin of this Department for October, 1909. 



Respectfully, 



Franklin Sherman, Jr., 



Entomologist. 

 To Hon. W. A. Graham, 



Commissioner of Agriculture.
