649. Though the sum of $147.41 per month may seen to be 

 a large figure to people who have not had experience in this 

 business, it will be found that the items are legitimate and must 

 be paid for directly or indirectly, sooner or later, by every 

 creamery. On the other hand, the figures given are estimated 

 and may be made greater or less at different factories. 



650. By carrying the calculation still further, we find that 

 if 180 pounds of butter are made daily from the 4,000 pounds of 

 milk, the cost of making this butter for the month is nearly 2.8c 

 per pound. This it will be seen is very nearly 3 cents per pound, 

 which is a rather common charge among creameries. This illus- 

 tration should not be understood as a recommendation of 3 cents 

 per pound, as the standard creamery price for making butter, for 

 the reason that there are localities in which a creamery cannot 

 be successfully operated for 3 cents per pound commission; but 

 even in such cases it may be for the best interest of the farmers 

 to have a creamery in operation at such a price per pound for 

 making as will give it a living profit. 



IV. The Creamery Building. 



651. Drainage. In selecting the site for a creamery build- 

 ing, the matter of drainage should be given careful considera- 

 tion, not only because a great deal of water is used about the 

 factory, but because of the nature of the drainage which comes 

 from a creamery. The daily washings contain more or less 

 milk, grease, etc., which decompose easily and makes the drain- 

 age a public nuisance unless properly disposed of. They may 

 also accumulate in the drain pipe until this is entirely closed up.
