304 DAIRYING. 



find how much butter each pound of fat makes. Multiply- 

 ing the amount received per pound of butter, less the cost 

 of making, etc., by this last result will give the amount to 

 be paid for each pound of fat delivered. 



Example : Suppose the patrons furnish milk containing 

 in all 400 lbs. of fat, which made 460 lbs. of butter, selling 

 for 27 cents per pound. The expense of making the butter 

 is found to be, e.g., 4 cents per pound. 27-4= 23 cents; 

 460 divided by 400 equals 1.15; 23 multiplied by 1.15 equals 

 26.45, which is the amount, in cents, to be paid per pound 

 of fat delivered; 26.45 X 3 = 79-35. or nearest 79 cents, is 

 then the money to be paid for 100 lbs. of 3 per cent milk, 

 and (see table) 90 cents for 100 lbs. of 3.40 per cent milk, 

 $1.24 for 100 lbs. of 4.7 per cent milk, etc. 



4. A certain price is to be paid per lOO lbs. of milk of average 

 quality. Find the total fat contained in the milk as before; 

 divide this amount by the total weight of milk delivered, 

 and the result will be the average per cent of fat in the 

 milk. Starting from this per cent at the left of the table, 

 go to the right until the price per 100 lbs. agreed upon is 

 reached; the perpendicular column in which this figure is 

 found is the one to be used. Example: Suppose milk of 

 average quality is to be paid $1.00 per hundred pounds, 

 and the farmers furnish 8500 lbs. of milk, containing in all 

 440 lbs. of fat; 440 divided by 85.00 then equals 5.18, the 

 number nearest to which in the table is 5.20 per cent. To 

 the right of 5.20 per cent $1.00 is found in the column 

 headed .58, which column would be the one to use.
