ings and equal opportunities, they have drifted far apart in 

 character. 



It is not a difference of hide or horns or temper; not that 

 one is wild and the other a pet ; it is not a difference of beauty or 

 intelligence or morals. The only difference worthy of note is a 

 difference in work in eaning money for the owner. Here is 

 how they differ. 



The Two Records for "T..ree Years. 



The milk of each of these cows has been weighed and tested 

 and an exact record of its amount and quality kept for the 

 whole period, and every pound of the feed consumed by each cow 

 both summer and wintter has been set down in definite terms. 



During the past three years cow No. 1 has produced 34,171 

 pounds milk containing 1,214 pounds butterfat, and cow No. 2 

 in the same time has yielded but 11,491 pounds milk with 414 

 pounds butterfat. This makes the annual production of the one 

 11,390 pounds of milk and 404 2-3 pounds fat; and of the other 

 3,830 pounds milk and 138 pounds butterfat. 



These cows were cared for in the same way and given the 

 same kinds of feed and encouraged to eat all they could make 

 good use of. Cow No. 1 ate 1.56 times as much as cow No. 2, 

 but produced 2.97 times as much milk and 2.93 times as much 

 butterfat. Or reduced to a like feed basis, No. 1 produced 1.88 

 times as much as No. 2. 



259 vs. 138 Tfos. Fat on the Same Feed. 



Feed fed to No. 1 produced 1.88 times as much butterfat as 

 when fed to No. 2, that is equal amounts of feed made 188 

 pounds fat when fed to No. 1, but only 100 pounds when fed to 

 No. 2. Each year, No. 2 got only 138 pounds butterfat from 

 the same quanity of food that No. 1 changed into 295 pounds fat. 

 The one cow is nearly twice as good a producer as the other on 

 exactly the same feed. 



This sounds significant. It gives a big hint as to the kind 

 of cows to keep. But it represents only the parting of the ways. 

 Let us follow these cows further. What does this difference mean
