TEST OF CREAM SEPARATORS. 



During the session of our Short Dair}- Course for 1894, there

The separators, as shown in the accompanying cut, were mount- 

 ed on solid stone piers and each was driven hy a separate counter 

 shaft which in turn received its power from the main shaft running 

 through the building. The power was furnished by a 25 horse 

 power Westinghouse engine which furnished ample power to run 

 all the separators at once and maintain the main shaft at a very
