216 “‘TWENTY-FIFTH ANNIVERSARY REPORT. 
CREAM AND BUTTER PRODUCTION. 
For the sake of uniformity in comparison, we make all the cream 
contain 20 per ct. of fat and assign it a market value of 20 cents a 
quart. In calculating the profits derived from selling cream, we 
deduct the value of the serum or skim-milk, that is, the cream less 
the milk-fat, assigning a value of 12% cents a hundred pounds. 
The yield of butter is obtained by deducting 0.16 as lost in skim- 
ming and churning from the fat present in 100 pounds of milk 
and calculating the remainder into butter containing 85 per ct. of 
fat. The value of the butter is fixed at 25 cents a pound. The 
following table gives the results:

CHEESE PRODUCTION. 
A large amount of work has demonstrated that, knowing the per- 
centage of fat and of casein in milk, one can with fair accuracy de- 
termine the yield of cheese (green) by multiplying the percentage 
‘f fat by 1.1 and adding to this result the percentage of casein mul-
