SIR: I submit herewith a report on the feeding value of coreals, by 

 Joseph Chamberlain, Chief of the Cattle-Food and Grain Laboratory 

 of the Miscellaneous Division, acknowledgments being due to Mr. 

 H. W. Houghton, assistant chemist, who performed the analytical 

 work on a portion of the samples examined, and to Mr. T. C. Trescot,
