-66 Testing Milk and Its Products. 



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



TABLES VII, and VIM. Find the test of the milk in table VII o* 

 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 p'-'inda of fat Is contained In 8925 lbs. of milk 

 testing 3. to per cent.? Ou p 264, econd column the lest 3.65 1b found, and 

 by going downward In this cw.uniu we have: 



8000 lbs 292. Iba. 



9U0 lbs 82.9 lbs. 



20 lbs 7 lbs. 



5 lbs 2 lbs. 



8925 lbs. of milk. 825.8 lbs. of fat. 



8925 lbs. of milk testing 3.66 per cent., therefore, contains 825.8 lbs. of 

 butter fat. 



TABIC 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 thG table is, 



otherwise, as explained above. 



Example: How much money is due for 325.8 lbs. of butt«r fat at 153^ 

 cents per pound? In the horizontal row of figures beginning with 1514 on 

 p. 217, we find i 



800 lbs _ $46.50 



20 lbs 3.10 



e lbs 77 



.8 lbs 12 



825.8 lbs. J50.49 



825.8 lbs. of butter fat at 15}^ cents per pound, therefore, la 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 lbs. of milk testing 3.8 per cent 

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

 3.8, we find : 



6000 lbs 209.0 lbs. 



800 lbs 33.4 lbs. 



40 lbs 1.7 lbs. 



5 lbs 2 lb». 



6845 lbs. 244.8 lbs. 



5845 lbs. of milk test ng 3.8 per cent, of fat will make about 244.8 lbs. of 

 butter, under oondltiuus similar to those explained in par. 220.
