INCREASE IN CORN FOR THE SILO AS IT APPROACHES 
MATURITY. 
How much increase is there in a crop of corn for the silo during the 
latter period of its growth? To answer this question and to learn 
something of the nature of the chemical changes which take 
place, a field of Burrell and Whitman corn, intended for the silo, 
was divided into two parts; each alternate set of four rows was cut 
September 11, and the remaining portion allowed to stand 
until a later date. There was a little less than two acres in the 
field, but we give the results calculated per acre as being more 
convenient. ‘The corn as fast as cut was placed upon wagons and 
drawn to the barn, where it was weighed and then at once cut into 
the silo. By dividing the field into sets of four rows each we 
were able to secure more uniform conditions than would otherwise 
be possible, besides giving the remaining corn a better chance to 
grow. Several samples were taken from different parts of the field 
and brought to the laboratory and the water content determined. 
Later an analysis was made to find the chemical composition of 
the dry matter. At this date, September 11, the corn varied 
from full silk to the watery stage of the kernels. 
September 29, from fear of threatening frosts, the remaining 
eorn was cut, weighed and sampled for analysis, and a silo 
adjoining the first filled. When the silos are opened samples of
