GETTING THE PROCESS OF MILK
 TESTING DOWN FINE.

How to Prorate the Value of SIilk When Tested by the Babcock or a Similar Mschinc-In Figuring Carry Out the Fractions of Mills In DecimaIs.
 First-Take fair sample of milk, and find by the rules given for using the ma chine the per cent. of fat an the milk, then by multiplying the weight of the whole body of milk from which the sam pie came by the per cent of fat found it will show the whole weight of fat in the milk weighed in. From day to day through the month, or as often as tests are taken during the month, credit each patron with the weight of the fat in the milk the test applies to. For instance, if one days milk of 300 pounds shows { per cent. milk, give the patron credit for twelve pounds of fat in the cheese or butter that is subsequently, included in a sale. If tests are made once a week add together weight of milk back to former test, whethe. milk was delivered lx or seven days, as the case may be, and multiply the aggregate weight by the per cent. shown by the test.
 Second-When a sale is made aster- tain the weight of fat of all the patrons that has entered into the weight of the butter or cheese sold. From the sum obtained from the sale of either product, or from both, if both are made, from the milk, deduct the cost of manufacture; then, using the aggregate weight of fat in the sale as divisor, and the sum of money left, after deducting the cost of manufacture, as a dividend, find the value of one pound of fat in either the butter or cheese, or both, if both are made and are in the sale. Then multi ply the weight of the fat each patron has % his credit by the price found for one pound, and pay him so many dollars and cents. Example:

 Total paid the foar patronA. ........... .sTsasl which is within eight cents of the bal ance ill the pool. as shown above. and that is about as "close shave" as the average mathematician could make in working out a dividend, unless he had a hint from omniscience just how far he had better take in or leave out frac- tions of mills. l have purposely taken not round numbers for weight of milk, or per cent. of fat or price of cheese, because it comes as it happens on the books of the factory, and so put my self in the cheesemaker's place and help him all can.
 want to also call attention to the ab- solute necessity of having the mills and fraction of mills carried out st least three figures to the right of the decimal in getting the value of one pound of fat for the multipler of the aggregate fat of each patron, for the price of the pound . a very intense representative of the money in the pool.-J.
