ANALYSIS OF INDIVIDUAL STALKS OF THE CORN PLANT. 
From a tenth acre plat of Waushakum corn thirty stalks, each bearing 
two ears, in as nearly the same state of development as could be 
determined by a superficial examination, were selected August 18, 
1882, and a label affixed to each, The kernels of corn were just 
beginning to swell, showing that they had already been fertilized with 
pollen. Commencing at this date, and at intervals of one week there- 
after, viz.: August 18, August 25, September 1, September 8, Septem- 
ber 15 and September 23, five of these selected stalks were taken and 
analyzed separately, in the same manner. ‘lhe analyses, not only gave 
a good average for the composition of the corn plant at each stage of 
development but are especially interesting, showing as they do the 
marked difference between individual stalks. ‘The variation found 
between stalks of the same variety of corn grown under the same con- 
- ditions of cultivation, soil and climate is almost as great as between | 
different varieties grown in different parts of the country. 
In each case duplicate determinations were made of the ash and 
nitrogen, the figures given being the mean, only one determination 
was made of the fat or of the crude fiber, unless there was reason for 
suspecting an error. 
The result is presented in full.
