A PRACTICAL DEMONSTRATION ON SIX FARMS. In order to demonstrate the practical value of the three essential factors previously mentioned they were applied on six farms in the vicinity of Grove City, Pa., with the voluntary coop- eration of the dairy- men. Five of the farms sent milk and one sent cream to the experimental cream- ery operated at Grove City by the Dairy Division.

The scores of the six farms, according to the dairy-farm score card used by the Dairy Division, United States Department of Agricul- ture, were as follows: , 42, , , , and out of a possible 100.
