DISCUSSION OF THE RESULIsS: 
With the exception of the preliminary period at the begin- 
ning of the experiment, each of the fodders was fed two or 
more weeks, and the actual test covered the last nine days of 
this period. ‘The milk was weighed at each milking, and a 
combined sample of the night’s and morning’s milk of each 
cow was taken for fat determinations by the Babcock test. A 
composite sample, covering two or three days, was also taken 
from each cow’s milk, and determinations of the total solids of | 
the milk were made three times weekly. ‘These determinations 
were made regularly throughout the experiment, including 
the preliminary part of each feeding period. The daily yield 
of fat for each cow was calculated from the weight of each 
day’s milk and the corresponding percentage of fat, and by 
adding the daily weights the total fat for nine days was 
obtained; and the yield of solids from each cow was obtained 
from the two or three days’ yield of milk and the corresponding 
percentage of solids, and these two and three days’ yields were 
added to obtain the total solids for nine days. ‘The butter 
corresponding to the nine days’ fat yields was obtained by 
adding one-sixth to the weight of the fat. 
It will be noticed that the two lots of cows were quite uniform 
in the amounts of milk and of fat produced during the oat and 
pea period (1) when both lots had the same kind of fodder. 
As soon, however, as cows 5, 6 and 7 were given oat fodder in 
place of oats and peas, although the dry matter of the ration 
was larger than before, there was a marked falling off in pro- 
ducts. This cannot be well accounted for except in the fact
