MODERN BTJITER MAKING. 



per cent, Table No. VIII. This shows how easily 

 the overrun may be reduced by reading the test 

 while the test is too hot, and how easily it can be 

 increased by reading the test when it is too cold, or 

 by including the full meniscus, or by not including 

 the meniscus in reading milk tests. Not only is the 

 overrun affected by the above mentioned conditions, 

 but not infrequently by deliberate over or under- 

 reading of milk or cream tests. 



37. The effect of under-reading cream tests. Table 

 No. IX. Assuming that 800 lbs. of butter fat is re- 

 ceived in 3,200 lbs. of cream testing 25 per cent. 

 Butter made contains 80 per cent butter fat and the 

 loss incident to its manufacture is 1 per cent. 



TABLE IX. 



'J'lir J'lffcrl of Underreading Cycuhi Tents. 



The above table shows that for every .5 per cent 

 reduction in reading 25 per cent cream, the overrun 

 is increased by about 2.7 per cent. The higher the 

 cream tests are, the less is the increase in overrun 

 due to reduced reading.
