The best cow in herd 23, produced 4,337.2 pounds of milk, con- 

 taining 215.55 pounds of butter fat, while the best one in herd 3 

 gave 9,454.3 pounds of milk, containing 324.08 pounds of butter 

 fat. The latter produced twice as much milk and one and one- 

 half times as much butter fat as did the former. You will also 

 notice that the best cow in herd 24 produced 477.3 pounds of 

 butter fat, which is more than twice as much as was produced 

 by the best cows in herd 16, 17 and 23. In three of the eighteen 

 herds reported the best cow produced more than 350 pounds of 

 butter fat; in five, between 300 and 350 pounds, and in five the 

 production ranged from 250 to 300 pounds. The range of but- 

 ter fat production extends from 202.7 pounds to 477.3 pounds, 

 which at the price assigned gives a possible return per cow of 

 from $50.67 to $119.32. After noting this variation in the best
