It appears from these averages that under the conditions existing 

 in Maine, which require the cutting of the large varieties of corn in 

 an immature state, the Maine field corn which reaches maturity, 

 contains the larger percentage of dry matter. This is true espec- 

 ially of the years 1892 and 1893, when the latter crop was more 

 perfectly developed. Again, the excess of dry matter in the Maine 

 field corn consists almost wholly of the Don-nitrogenous compounds 

 classed under the head of nitrogen-free-extract. The character- 

 istic differences in the composition of the dry substance of the two 

 varieties of corn are more clearly seen by a comparison in the water- 

 free condition.

The dry substance of the larger and immature corn contains 

 more ash protein and fiber and less nitrogen-free-extract and fat: 

 The much larger percentage of fiber and greatly less percentage of 

 nitrogen-free-extract are the noteworthy differences.
