DIRECTIONS FOR USE OF TABLES.The folowing pages contain complete tables for making an 80 lb.

blend of any per cent from 8'^ to 30 7f inclusive. This is done by mixingcream testing 15 Vc to 46 '< with skim-milk, or with any per cent of milkor cream from skim up to 30 'i.There are two rows of tests; i. e., one is the per cents of theheavier cream to be used, and the other, the per cents of the milk andthe lighter cream. The former is found in the horizontal row of testsand the latter in the vertical row. Find the test of the heavier cream,the number of pounds of this cream required to be mixed with skim-milk, milk, and other per cents of cream are then given in this verticalcolumn.

Example :How many pounds each of 20 Vc cream and 4% milk arerequired for 80 lbs. of an 8''< blend? In the S^'c table, find the A'/c inthe vertical row and the 20',; in the horizontal row of tests. The figure(20.00) where the horizontal and vertical columns meet is the numberof pounds of the 20'' cream required. Then 60 lbs., the remainder ofthe 80 lbs., is the amount of 4'r milk needed.

In any case the number of pounds given in the table is the weightof the heavier cream used.

As 8 lbs. is the average weight of a gallon of cream, 80 lbs. isapproximately 10 gallon. This weight has been taken as a basis forthese tables because 10 gallon is the quantity generally desired and alsothe amount i>om which any desired quantity can be most easily figured.

The method for determining the number of pounds needed for anynumber of gallons is as follows:

In the table the number of pounds required for ten gallon is given.For any number of gallons, other than ten, move the decimal point oneplace to the left, which gives the amount for one gallon, then multiplythis result by the number of gallons desired.

The table can be applied for using three or more different per centsof cream or milk. If one did not have enough of any two kinds tomake the desired per cent, a number of small amounts of different percents can be used.

Example:80 lbs. of 25"^/ cream is desired. 40 lbs. of 30''f ; 15lbs. of 247c ; and 30 lbs. of 18 'f are on hand. Applying the tables, wefind that 13.33 lbs. of 24 Cr, with 26.66 lbs. of 18 ';>;^ make 40 lbs. of 20 '^'r.This with the 40 lbs. of 30%, makes the required 80 lbs. of 25%.
