UNITED STATES DEPARTMENT OF AGRICULTURE, 



DIVISION OF CHEMISTRY, 

 Washington, D. <7., April 2, 1886. 



SIR : 1 have the honor to submit herewith for your approval the final 

 results of the investigations of American cereals which have been 

 made by this Division under the direction of Mr. Clifford Richardson. 

 These investigations, it is believed, are the most extensive and 

 thorough of any similar ones heretofore carried on, and have revealed 

 the influence of soil and climate on the composition of our grain in a 

 manner which will prove beneficial both to our farmers and manufact- 

 urers. 



Respectfully, 



H. W. WILEY, 



Chemist. 

 Hon. N. J. COLMAN, 



Commissioner.
