KENTUCKY BLUE GRASS. 95 



thin seeding of oats cut early for hay, the results will 

 probably be quite as good. 



Blue grass should not be sown in short rotations, since 

 it is slow in becoming well established. In rotations 

 of some considerable duration, it is frequently sown in 

 combination with medium red, mammoth or alsike 

 clover, or with all three combined, with white clover 

 and timothy added. The clovers and timothy are in- 

 tended to furnish grazing until the blue grass becomes 

 well established. Blue grass, orchard grass and white 

 clover make an excellent combination for such rotations 

 where the conditions favor the growth of all three. On 

 low-lying soils such as are found in sloughs, blue grass, 

 red top, timothy and alsike clover make a good combi- 

 nation for hay or for pasture. In latitudes in which 

 the winters are stern, blue grass, Russian brome grass 

 and white clover grown together, promise much for 

 such rotations, but experience in growing them thus is 

 not of sufficient duration to determine fully the value of 

 such a pasture crop. It is not yet known whether blue 

 grass or Russian brome if sown together would obtain 

 the mastery or if both would continue to grow indefinite- 

 ly. On lands once covered with forest, it is probable 

 that blue grass would crowd the Russian brome, but 

 that on real prairie soils the reverse would prove true. 

 When sown in mixtures intended for permanent pas- 

 tures, the relative prominence given to the blue grass 

 should increase with its relative adaptation to the local- 

 ity, and, even when blue grass is intended to be virtually 

 the sole grass in the pasture, white clover ought to be 

 sown along with it. The clover probably aids the growth
