2 THE MILK FACTORY 
of producing the maximum quantity and quality 
of milk from a given amount of feed. The dairy 
barn is the dairyman’s milk factory, and like 
the mill owner, he brings his raw material in one 
door and after passing it through the factory, takes 
his finished product out of another door.

Volume of business and expense decide profit 
or loss. (Volume means quantity.) Dairy ex- 
penses must be borne by every quart of milk, 
A dairy producing only 10 quarts of milk makes 
each quart bear 7's of the entire cost of operating 
the dairy. A dairy producing 200 quarts of 
milk makes each quart bear only zécth of the en- 
tire cost of operation. The expense of operating 
a 200-quart dairy is not 20 times as great as the 
expense of operating a 10-quart dairy. The di- 
vision of expenses among 200 quarts makes each 
quart carry a much smaller tax than where ex- 
penses are divided among only Io quarts. A 
sufficient volume of milk is necessary to pay the 
cost of good dairy operations. Small business 
means loss, while large business means _ profit.
