years if the cutting is fixed by date instead of by the maturity 

 of the crop. It is not possible as yet to state at just what 

 period of growth corn contains most sugar, but it is some- 

 where between the formation of the ear and the milk stage.* 



As the ear ripens the sugars change to starch in the kernels, 

 and decrease in the stalk and leaves.

Cutting corn for the silo at the period of growth yielding 

 the most sugars results in larger losses in the silo, since the 

 shrinkage in dry matter in 1899-1900 was much greater than 

 in 1S98-1S99 or 1900-190T.
