thinner, other conditions being equal. Third, the per cent, of fat changes 

 with the amount separated per hour. Milk should be run through the sep- 

 arator at a constant stream. If milk is fed at an uneven rate, or the 

 flow of milk is stopped, the thickness of the cream will be vastly in- 

 fluenced. Fourth, the amount of water or skim milk used to flush out 

 the bowl will naturally tend to affect the cream test. It is always well 

 to use a uniform quantity. And lastly, there is a ceram screw, in the sep- 

 ator bowl, for the purpose of changing the thickness of the cream when de- 

 sider. By this it can be so reguiaiea as to make thin or thick cream, 

 and when once set, if all the other conditions of the separation are 

 kept uniform, it will produce nearly a constant per cent, of cream. These 

 principles hold true in all centrifugal separation, and if such precau- 

 tions are taken, a cream quite uniform in test can be depended upon; at 

 any rate, far more uniform than can be obtained from the dilution sys- 

 tem. 



The idea of this paper is principally to discourage the use of the dilu- 

 tion system. I hope that some day that it will be eradicated from 

 the state. It is an ineffectual way of separating cream. But there are 

 many people today in the business who are attempting to sell these sep- 

 ators throughout the state. We occasionally hear of the large numbers 

 being sold in a certain county for sums vastly greater than they ought 

 to be sold at. When I hear of it, I feel like saying, like the boy said 

 when his father had served him with three or four servings and asked 

 him if he cared for a fifth he answered, "No, not another darned bit," 

 and I hope the time will come when we can say that to the dilution 

 cream separator in Illinois. 



DISCUSSION. 



Q. — What about the calves and pigs where using the dilution separa- 

 tor? 



A. — I am afraid they would have to live on pretty poor material.
