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 lutrogen 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 lilling the silo and feeding out the 

 silage. In the season of 191-1^15 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 host quality of silage.
