The hay was aftermath, with much clover, and was fine and in 
excellent condition. The grains as previously noted. 
We have two periods of nine days each in which the food was hay 
ad libitum, and these shall serve us for comparison. . The figures of 
these periods are herewith given:

If we divide the period of trial into nine days intervals, we have 
two periods under hay feed exclusively, and four periods under 
mostly brewers’ grains feeding, one of which, the earliest, can be ex- 
cluded on account of its transition nature. The figures, however, 
show as below : :

We have thus our answer very plainly outlined: the feeding of 
the brewers’ grains was conducwe to tite flow of milk.
