5. Value of Ice Cream. Since a gallon of 15% cream 
weighs 8.45 pounds, 100 pounds of 4% milk will make 
3.15 gallons of 15% cream (see formula for calculating 
cream, p. 240) or, allowing an-overrun of 33 1-3%, 4.2 
gallons of ice cream. At $1.00 per gallon this is worth 
$4.20. To this must be added the value of 73 pounds of 
skim-milk which, at one-half cent per pound, are worth 
37 cents, making a total value of $4.57 for the 100 pounds 
of milk made into ice cream. 
Summary. The preceding calculations show that 100 
pounds of 4% milk are worth 
$1.45 when sold as cheese, 
1.65 when sold as butter, 
2.03 when sold as cream, 
3.25 when retailed as milk, 
4.57 when sold as ice cream. 
It is to be remembered that the above figures show the 
relative gross returns at the prices given. The net re- 
turns will vary greatly, depending largely upon the near- 
ness to market and the quantity of milk handled; also to 
some extent upon the use to which the skim-milk is put. 
If fed to pigs and calves the value of skim-milk is less 
than one-half cent per pound; if made into buttermilk or 
cottage cheese its value may range from one to two 
cents per pound. 
Table of Values. The following table of values has 
been prepared for handy reference. The price of milk is 
used as a basis, and the table shows at what prices cream 
and butter must be sold to give the same returns as milk:
