The foregoing table gives analyses at different periods of 

 growth. 



This table shows the general tendency of the plant to 

 increase rapidly in all its parts up to August 6. After this the 

 stores are emptied into ear and grain, and additional increase 

 comes from the activity of the husks rather than from the 

 leaves. These, in so far as they are situated below the 

 eighth or ninth node, the usual seat of the ear, become 

 productively inactive and dry up, whilst those above them 

 yield their substance to the ear, and after drying represent a 

 less valuable material than the lower ones. Both become 

 very brittle when dry and are usually lost in the process of 

 harvesting. 



The following table, prepared for the United States De- 

 partment of Agriculture, collected from the reports of forty- 

 nine experiment stations and many other sources, including 

 the publications of schools, colleges and agricultural societies 

 in the United States and Canada, is a compilation of all 

 analyses published before September i, 1890. A variety of 

 methods were used in the determinations by the earlier 

 chemists, so that a slight discrepancy exists between the 

 results of the older and later published analyses.
