LETTER OF TRANSMITTAL 



Hon. W. a. Graham, Commissioner. 



Sir: — I submit herewith manuscript for a Bulletin on "Insect Ene- 

 mies of Corn." Corn is our most important crop, and the total damage 

 done to it by insects is enormous. The Bulletin which we issued upon 

 this subject in May, 1905, has been exhausted, and the matter which it 

 contained has here been rewritten to include later observations and to 

 avail ourselves of many excellent publications on corn insects which have 

 recently appeared from other States, thus bringing, so far as I am able, 

 the best present information into shape available to our farmers. The 

 general plan of the older Bulletin has been retained, as also the illustra- 

 tions. 



I recommend its publication as the Bulletin for May, 1914. 



Very respectfully, 



Franklin Sherman, Jr., 

 Approved for printing : Entomologist. 



W. A. Graham, 



Commissioner.
