262 MODERN METHODS OF TESTING MILK 



This rule can be made more clear by considering 

 the process in three separate steps, assuming that the 

 creamery is operated on the co-operative plan. 



Step i. By Rule I find the amount of milk- fat fur- 

 nished by each patron during the dividend period. 



Step 2. Find the net value of one pound of milk- 

 fat by dividing the total net receipts by the total num- 

 ber of pounds of fat delivered by all the patrons during 

 the dividend period. 



Step 3. Multiply the number of pounds of fat de- 

 livered by each patron by the net 'price received for 

 one pound of fat. 



Example: Step i. The data and results are indicated 

 in tabular form as follows: 



Pounds of Milk Per cent. Pounds of 



NAME OP delivered during of fat fat in milk 



PATRON dividend period in milk delivered 



A .... 350 x 4.0 = 14.00 



B .... 650 x 3.6 = 23.40 



C .... 835 x 5.2 = 43.42 



D . . * . 965 x 4.4 42.46 



E .... 1,200 x 4.2 = 50.40 



Total number of pounds of fat delivered by 



all patrons 173-68 



Step 2. From the amount of fat indicated above, 

 the amount of butter made was 195 pounds, which 

 realized 18 cents a pound after deducting all expenses, 

 making a total of $35.10. This sum divided by 173.68, 

 the total pounds of fat delivered, gives 20.2 cents as 

 the net price received for each pound of fat.
