total production of the 11 cows longest in the herd, how- 

 ever, are given in this article. 



It is obvious from a study of the table that cows pro- 

 ducing the most fat do not always produce the most milk. 

 Cow E, the best one in fat production and the fourth in milk, 

 produced an average of 292 lbs. of fat and 7,861 lbs. of milk 

 per year. The lowest producer, cow G, averaged 231 lbs. 

 of fat and 6,170 lbs. of milk. The whole range in fat pro- 

 duction was only 61 lbs. The highest cow was 21 lbs. above 

 the second, proving her in a distinct class from the others, 

 but the next four cows had almost} the same fat production, 

 varying only three pounds.

Cow I, which was fourth in fat production and first in 

 milk, gave 23 lbs. less fat than the first cow, but produced 

 1,104 lbs. more milk per year. She produced 2,795 lbs. 

 more milk than cow G, the lowest producer of the 11 cows 

 in both fat and milk, and 714 lbs. more milk than any of 

 the other cows. Cow F, although next to the highest pro- 

 ducer of milk, averaging 8,251 lbs., with the ninth cow in 

 production of fat. Cow J was third in milk, but seventh in

The best cow in fat production produced 61 lbs. or 26 

 per cent more fat than the poorest cow. The best cow in 

 milk production produced 2,795 lbs., or 45 per cent more

 fat, cows E and K, produced an average of 50.5 lbs. or 22
