1 The figures in this column represent the number of cubic centimeters of normal alkali required to 
neutralize the acids in 100 grams of the juice. 
Total weight of juice, 9,494. 5 pounds. Total weight of nitrogen calculated as protein, 150.75 pounds. 
DISCUSSION OF RESULTS. 
The investigation was conducted under all the difficulties inherent 
in practical farm conditions. The silo was not in any sense an 
experimental silo. The burial and removal of the bags took place 
during the regular course of rilling the silo and feeding out the 
silage. In the season of 1914-15 the filling extended over a period 
of 17 days and the feeding out took nearly 3 months from the first 
bag to the last. In the season of 1915-16 the filling took only 8 days 
but the feeding out extended over a period of nearly 7 months. In 
the former season the corn was considered somewhat overmature and 
for a few minutes during each day's run water was added through 
the distributer. In the latter season the corn was considered less 
mature than is desirable for the best quality of silage.
