".Two facts are clearly shown. First, that the latter 

 growth of dry matter in the corn plant is made up chiefly of 

 non-nitrogenous compounds; second, a large percentage of 

 these compounds consist of sugars and starch, substances that 

 are the best of their class for the purposes of animal 

 nutrition." 



Not only is the yield increased by allowing the 

 plant to mature, but contrary to general opinion the 

 mature material is actually more digestible, as is shown 

 by the following summary of American digestion 

 experiments compiled by Jordan: 



DIGESTED FROM lOO PARTS OF ORGANIC MATTER 



Cut before glazing, 13 experiments 

 Cut after glazing, 10 experiments 



Applying these figures for com fodder to the 

 yields shown by New York experiments in the preced- 

 ing table, it is found that an acre yielded of dry
