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,} as prepared by Mr. 
W. H. Beal, of the Office of Experiment Sta- 
tions, Washington, D. C.:
