Testing Milk and Its Products. 



Example 1: It has been decided to pay 90 cents per 100 Ibs. 

 of 4 per cent. -milk. The figure 90 is then sought in the table in 

 the same line as 4.0 per cent., and the vertical column in which 

 it is found gives the price per 100 Ibs. of 3 to 6 per cent.-milk. 

 3.8 per cent.-milk is thus worth 85 cents per 100 Ibs. and 4.2 per 

 cent.-milk, $1.01, under the conditions given. The prices of 

 milk of other qualities are found in the same way. 



Example 2: In the example referred to under Illustrations 

 of calculating creamery dividends (I b, 231), the figures for the 

 patrons No. 1, 2 and 3, would be as follows: 



238. Milk and cream dividends. When cream from farm 

 hand separators or other sources is brought to a factory 

 receiving and skimming whole milk, the cream patron's 

 dividend should be calculated a little differently than 

 that of the milk patron. 



In one case the dividend is based on the weight and the 

 test of cream and in the other on the weight and the test 

 of milk; the difference between the two being represented 

 by the fat left in the factory skim milk. This skim milk 

 fat is included in the milk patron's dividend and conse- 

 quently ought also to be allowed for in calculating the 

 amount due the cream patron. Such an allowance can 

 be very fairly made by multiplying the cream fat by 1.03. 

 This is assuming that the one-tenth or more of fat re- 

 turned to the milk patron in his skim milk is about 

 three per cent, of the total fat in his whole milk. 



Both milk and cream patron suffer the same manufac- 

 turing loss in the factory butter milk so that an equaliza-
