COMPOSITION AND DIGESTIBILITY. 



159 



Mr. H. J. Patterson,* Chemist at the Maryland 

 experiment station, shows the yield in pounds 

 per acre of the digestible matter in the differ- 

 ent parts of the corn plant. 



The fertilizing constituents to be found in 

 the corn plant as a whole, or in its several parts 

 or by-products, are given in the following table. 

 These figures are the averages of many pub- 

 lished American analySes,i- as prepared by Mr, 

 W. H. Beal, of the Office of Experiment Sta- 

 tions, Washington, D. C:
