240 Testing Milk and Its Products. 



Directions for Use of Tables VII, VIII, IX, and XI. 

 TABLES VII, and VIII. Find the test of the milk in table VII or 

 of cream in table VIII; the first or last horizontal row of fig- 

 ures, the amounts of fat in ten thousand, thousands, hundreds, 

 tens, and units of pounds of milk are then given in this verti- 

 cal column. By adding the corresponding figures for any given 

 quantity of milk or of cream, the total quantity of butter fat 

 contained therein is obtained. 



Example: How many pounds of fat is contained in 8925 Ibs. of milk 

 testing 3.6-5 per cent.? On p. 242, second column the test 3.65 is found, and 

 by going downward in this column we have : 



8000 Ibs 292. Ibs. 



900 Ibs 32.9 Ibs. 



20 Ibs 7 Ibs. 



6 Ibs 2 Ibs. 



8925 Ibs. of milk. 325.8 Ibs. of fat. 



8925 IbB. of milk testing 3.65 per cent., therefore, contains 325.8 Ibs. of 

 butter fat. 



TABLE IX. The price per pound is given in the outside vertical 

 columns, and the weight of butter fat in the upper and lower 

 horizontal row of figures. The corresponding tens of pounds 

 are found by moving the decimal point one place to the left, 

 the units, by moving it two, and the tenths of a pound, by 

 moving it three places to the left. The use of the table is, 

 otherwise, as explained above. 



Example: How much money is due for 325.8 Ibs. of butter fat at 15% 

 cents per pound? In the horizontal row of figures beginning with 15% on 

 p. 217, we find : 



800 Ibs $46.50 



20 Ibs 3.10 



6 Ibs 77 



.8 Ibs .12 



325.8 Ibs. 850.49 



825.8 Ibs. of butter fat at 15% cents per pound, therefore, is worth $50.49. 



TABLE XI. Find the test of milk in the upper or lower hori- 

 zontal row of figures. The amounts of butter likely to be made 

 from ten thousand, thousands, hundreds, tens, and units of 

 pounds of milk are then given in this vertical column. The use 

 of the table is, otherwise, as explained above in case of table VII. 



Example: How much butter will 5845 Ibs. of milk testing 3. 8 per cent, 

 be apt to make under good creamery conditions ? In the column headed 

 3.8, we find : 



5000 Ibs 209.0 Ibs. 



800 Ibs 33.4 Ibs. 



40 Ibs 1.7 Ibs. 



5 Ibs.... .2 Ibs. 



5845 Ibs. 244.3 Ibs. 



5845 Ibs. of milk testing 3.8 per cent, of fat will make about 244.3 Ibs, of 

 butter, under conditions similar to those explained on pp. 184-188,
