ready to harvest over 53 # of the dry matter was in the stalks and leaves 

 and but 46.32 $ in the ears. 



Undoubtedly the most valuable single nutrient in the corn is the pro- 

 tein. The following table shows the distribution of the protein at the 

 different dates:

Ie all the earlier stages of growth, the greater share of the protein is 

 found in the leaves; and even when the corn is ripe enough to cut, but 

 little over half of it is found in the ears. This fact calls attention again to 

 the necessity of carefully housing and preserving the fodder. 



The next table which gives the distribution of the albuminoid nitrogen 

 should be studied in connection with the one just given,, relating to the 

 total protein.

It seems that when the corn is in the roasting ear and the whole plant is 

 vascular but 2.53 # of all the albuminoid nitrogen in the plant is resident 

 in the stalks, even at this date nearly half of the albuminoid nitrogen of 

 the entire plant is found in the ear, immature as it is. When the crop is 

 ready to cut nearly sixty per cent of the albuminoid nitrogen is found in 

 the ear. 



Turning now to the class of soluble non-nitrogenous substances in- 

 cluded, by the chemists, under the term nitrogen-free extract and contain- 

 ing such nutrients as starch and sugar the following table shows how 

 their distribution changes at the four dates given.
