The increase in the circumference of the chest varied from 2.5 to 
12.5 inches, most of the steers showing an increase of 6.5 to 9.5 inches. 
Table II shows that the steers having a large increase in the circumference 
of the chest have been those steers that had made the greatest daily 
gains. (It is true that the more a steer gains the greater is the amount 
of covering of flesh over the ribs or around the chest circumference.)
