Passing on to table 3, let us study for a moment the average 

 production of the cows in the different herds. The average pro- 

 duction of herd three is seen to have been 88,056.78 pounds of 

 milk and 275.78 pounds of butter fat from five cows. By not- 

 ing the highest and lowest production in this herd as shown in 

 tables 1 and 2, it is obvious that they are uniformly high produc- 

 ers. The same thing is true in herd six, where the number of 

 cows is greater and the butter fat production larger. Herd 23 

 has the lowest average production, which is 3,314.10 pounds of 

 milk and 142.05 pounds butter fat per cow. In the different 

 herds, the average return per cow on the butter fat basis varies 

 from $35:51 to $87.54. When we reflect that the average cost 

 of feeding a cow for a year varies under different conditions from 

 $35 to $45, the profit per cow in some instances becomes a nega- 

 tive quantity. There is a vast difference between a return of
