LETTER OF TRANSMITTAL. 



U. S. Department of Agriculture, 



Bureau of Animal Industry, 

 Washington, D. C, August 12, 1911. 

 Sir : I have the honor to transmit herewith, and to recommend for 

 publication in the bulletin series of this bureau, a manuscript entitled 

 " The Maintenance Rations of Farm Animals," by Dr. Henry Pren- 

 tiss Armsby, who has charge of the cooperative work in animal 

 nutrition between this bureau and the Institute of Animal Nutri- 

 tion of The Pennsylvania State College. The paper is based not 

 only on Dr. Armsby's own work, but on that of other investigators 

 as well, and is believed to cover the subject thoroughly. 

 Respectfully, 



A. D. Melvin, 

 Chief of Bureau. 



Hon. James Wilson, 



Secretary of Agriculture.
