Although there was some variation from one year to the next in the 
quantity of beef produced per acre by each of the classes of cattle 
under study, no one of the three years appears to have been excep- 
tionally favorable or unfavorable to all classes. (Figs. 6 and 7.)

Fig. 7.— The annual production of beef per acre of grass varies as between kinds of steers 
usually had from 4 to 5 acres of grass per head. Thin 2-year-old 
steers had about the same area as thin aged steers, and thin yearlings 
had from 3 to 4 acres per head. 
Thin aged steers made greater daily gains than the other classes 
of cattle. They had fewer acres per head than the half-fat aged or 
the fat aged steers but made more rapid gains. The thin aged steers
