It will be noted that the highest gains per head are secured in the 100-acre and the 70-acre pastures. The gains of the cattle in these two pastures are now looked upon as the normal maximum gains per head that may be expected from the native forage. Both of these pastures had abun- dant feed left standing at the close of each season. Therefore, the quantity of available feed could not have been a limiting facto; m the production of gains. This is also further shown by the fact that the gains in these two pastures have been practically equal. The small difference in favor of the 70-acre pasture is considered of minor significance. The gains in the 100-acre pasture may be influenced by its size and also by the fact that through it is the entrance to the
