the same power or steam. The accumulating results of 

 such trials being compiled, however, become a guide in 

 estimating the value of the various machines in the 

 market. As between belt and turbine (or direct steam) 

 power, the former is preferable in large creameries. In 

 small plants one is about as economical as the other, and 

 the choice may depend upon whether an engine is needed 

 J for churning, butter-worker, pump, and other purposes, or 

 you can do without it. 



Capacity. — In selecting a separator it is best to have 

 plenty of capacity. In a large creamery it is better to 

 have two separators of moderate size than one very large 

 machine. Only in very large creameries may separators 

 of largest capacity be preferable. The capacity should be 

 such as to finish the day's work in 4 to 6 hours at the time 

 when there is most milk. In the private dairy, using a 

 hand separator, the work should require only one hour, 

 rather less. The following would be our idea of the proper 

 capacity: 



Condition of Creatn. — As discharged from the separator, 

 the cream should be 'smooth and even, free from froth and 

 of perfect ** churnability." 



As to cost, the best machine is ahvays the cheapest in the long 

 run. Repairs, waste of fat in the skim-milk, of oil, and of 

 coal, by an inferior machine, will more than make up any 

 saving in first cost.
