PROFITABLE DAIRYING 



It would be easiest for him to dilute the cream 

 with skim-milk, which we will assume tests 0, 

 although it may test .1 of 1.0 per cent fat; for 

 practical work, however, it may be said to test 

 nothing; 0, therefore, is placed in the lower left- 

 hand corner. His contract calls for a 25 per cent 

 cream, and 25 is placed where the diagonal lines

cross in the center of the square. Subtracting 25 

 from 30 and following the diagonal line we place 

 the difference, 5, in the lower right-hand corner. 

 The difference between and 25 is 25, and we put 

 that in the upper right-hand corner on the other 

 diagonal. We now have figures in each of the 

 four corners. The diagram may now be explained 

 as follows, reading from left to right in the usual 

 way: Of the 30 per cent cream we take 25 pounds, 

 and of the skim-milk 5 pounds ; pouring these two 

 together we have 30 pounds of 25 per cent cream. 

 In other words, for every 25 pounds of 30 per 

 cent cream, 5 pounds of skim-milk must be added
