Step 3. The data and results are indicated in tabu- 

 lar form, as follows : 



Pounds Net price A mount of 



NAME OF of fat received for fat dividend due 



PATRON delivered per pound each patron 



A . . 14.00 x 20.2 cents = $2.83 



B . . 2340 X = 473 



C . . 4342 X = 8.77 



D . . 42.46 x = 8.58 



E . . 50.40 x = 10.18 



When both milk and cream are used in a creamery, 

 the pounds of fat delivered in the form of cream are 

 found by applying Step i above and then multiplying 

 the result by 1.02. From this point on, the process of 

 calculating dividends is the same as above described. 



13. FINDING DIVIDENDS ON FAT BASIS AT 

 CHEESE-FACTORIES 



Rule. To calculate the amount of each patron's 

 dividend at cheese-factories on the basis of the fat in 

 the milk, proceed as under Rule 12. 



14. FINDING AMOUNTS OF MILK, ETC., TO USE 

 IN MODIFYING NORMAL MILK 



The practice of modifying or standardizing milk 

 for special market purposes is constantly increasing. 

 This consists in increasing or decreasing the per cent, 

 of fat in a normal milk. The per cent, of fat in a 

 normal milk may be increased (i) by adding cream, 

 (2) by adding milk richer in fat, or (3) by skimming 

 part of the normal milk with a separator and then put-

 normal milk. The per cent, of fat in a normal milk
