192 Testing Milk and Its Products. 



holders who is elected secretary attends to the details of 

 running the factory and selling the product. His ac- 

 counts show the amount of money received each month 

 for the butter and other products sold, and the expenses 

 of running the factory during this time. The expenses 

 are substracted from the receipts, and the balance is 

 divided among the patrons, each one receiving his pro- 

 portionate share according to the amounts of butter fat 

 delivered in each case (as shown by the total weight and 

 the average test of milk delivered during this time). 



In nearly all cases, the farmers receive about eighty 

 pounds of skim milk for each hundred pounds of whole 

 milk they deliver to the factory, in addition to the 

 amount received for the milk, calculated according to 

 one or the other of the preceding methods. 



229. Illustrations of calculations of dividends. In order 

 to illustrate the details of calculating dividends, or the 

 amount to be paid each patron for the milk supplied 

 each month, when payments are made by each of the 

 four systems given, it will be assumed that a creamery 

 receives 5000 pounds of milk daily for thirty days, and 

 makes 6650 Ibs. of butter from the 150,000 Ibs. of milk 

 received during this time. The average test of this milk 

 may be found by multiplying the total weight of milk 

 delivered by each patron by his average test, and divid- 

 ing the sum of these products by the total weight of milk 

 received at the creamery (in the example given, by 150,- 

 000), the quotient being multiplied by 100. Such calcu- 

 lations may show that, e. g., 5700 Ibs. of butter fat have 

 been received in all in the milk delivered by the differ- 

 ent patrons; this multiplied by 100 and divided by
