.ETTER OF TRANSMirrAL 



U. S. Department of Agriculture, 



Division of Entomology, 

 Washington., D. C, May 10, 1902. 

 Sir: 1 transmit herewith cop}^ of an article entitled "How Insects 

 Affect Health in Rural Districts," and have the honor to recommend 

 the publication of the same as a Farmers' Bulletin. The article was 

 originall}^ prepared by me for the Yearbook for 1901, in which it 

 appears under a different title, but in view of the very general interest 

 in the subject it seems desirable to republish the matter in the pres- 

 ent form for distribution to farmers, to whom, it is believed, the bul- 

 letin will prove of special interest and value. 



Very respectfully, L. O. Howard, 



Entomologist. 

 Hon. James Wilson, 



Secretary of Agriculture.
