 essential for good churning. Most of the gravity-skimmed 

 cream is too poor in butter-fat. 



"5. Less butter-fat remains in the skimmed milk." 



The relative skimming efficiency of the hand-separator, as 

 compared with the older gravity systems, is given by Hunziker 1 

 as follows : 



If the dairy contains several cows, the saving in cream by 

 the use of the hand-separator will be an important item. 

 Taking all the advantages of this method into consideration, 

 the purchase of a hand-separator will, under ordinary condi-

 Selection of the separator. 



At the present time, there are many kinds of hand-separators
