210 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 
fats; The value: of the buttersts suxédaaty2 Secenteea. pouiieeet le

CHERSIO*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 
sf fat by 1.1 and adding to this result the percentage of casein mul-
