NORTHERN GREAT PLAINS FIELD STATION, 1913-1922 79 
The 70-acre deferred and rotation pasture during the three years 
from 1920 to 1922, inclusive, has been grazed at the rate of one 2-year- 
old steer to 4.375 acres. This system of grazing has resulted in a 
high utilization of the vegetation. The gains of the cattle have been 
about 10 per cent below the best gains made. The vegetation in this 
pasture has not been injured by the high degree of utilization. 
This was because the vegetation in the different divisions of the pas- 
ture was allowed to mature periodically before it was subjected again 
to grazing.
