32 STORRS AGRICULTURAL EXPERIMENT STATION. 
The average production of butter fat ranged from 190 pounds 
in herd No. 1 to 319 pounds in herd No. 5. ‘The difference in 
the average production of these two herds might be attributed 
in part to a difference in feeding, care, and management. In 
the opinion of the writer, however, the variance in a large 
measure was due to the difference in the breeding and the 
individuality of the cows in the two herds. 
Dividing the herds into three divisions according to pro- 
ductive capacity, we have the following table:
