Table II. shows what happens when a farmer becomes a 

 dairyman. The owner of this herd after testing twice, discov- 

 ered that his cows were yielding only 4.88 lbs. of butter fat per 

 week. They were ordinary nondescript cattle which he sold and 

 replaced by high grade dairy cows. Both the old and the new 

 are compared in Table 11. showing that with all things com- 

 parable the latter were practically twice as good as the former. 

 This man began to see the dawn of prosperity and bought more 

 high grade cows with the result that now he has an excellent 

 herd yielding between 8,000 and 9,000 pounds of milk and well 

 above 300 pounds of butter fat. His original herd would 

 alw^ays have kept him in the rut.
