The total starch per acre increased more than twenty-three 
times between tasseling of corn and harvesting, a period of fifty- 
five days. From the stage of glazing of corn until full ripening 
the increase in dry matter was 716 pounds, the increase in 
nitrogen-free extract, 587 pounds, while the increase of sugar and 
starch was 989 pounds, or greater by 273 pounds than the entire 
gain in crop. That is, much of the nitrogen-free extract which at 
period of glazing of corn was in the transitory state had been 
translocated and transformed into sugars and starch. 
The conclusions reached last year with B. & W. corn are in 
the main borne out by the present season’s investigation, and the 
results of two years’ work given in a short summary are as 
follows : e 
| CONCLUSIONS. 
1. That the greatest weight of green fodder is between the 
period of full silking and milky stage of kernel. | 
2. That the total weight diminished after this date but the total 
dry matter increased. 
3. That as the corn approaches maturity the per cent of amide 
nitrogen diminishes, while the albuminoid nitrogen increases, Bi: 
thus seemingly increasing the feeding value of the crop. 
4, That the sugars and starch increase rapidly during the latter 
period of growth and maturing of the corn plant, and that these — . 
are the most valuable portion of the nitrogen-free extract. 
5. That between the period of glazing and full ripening of corn — 
- there was a large increase in amount of sugar and starch. 
6. That for the greatest amount of nutriment, considered from 
_ a chemical standpoint, corn should not be cut before it has well — 
ripened. . 
7. That the B. & W. corn can not, in ordinary culture, be 
matured in this latitude. 3
