 a little white clover to any of the mixtures referred to. 

 In, some instances it may not b© necessary to sow blue 

 grass in these, since, in certain soils on which it has 

 been grown for some time, these would seem to be so 

 filled with the seed that blue grass within two, three or 

 four years, will have possessed the soil to the extent of 

 crowding the other grasses to their injury. 



When purchasing blue grass seed, much attention 

 should be given to the character of the same in regard 

 to cleanliness, more particularly in regard to freeness 

 from chaff. The standard weight of blue grass is 14 

 pounds to the measured bushel, and yet as handled by 

 seedsmen the weight varies from 8 to 30 pounds per 

 bushel. This point should not be overlooked when deter- 

 mining the amount to sow. 



Pasturing. — Under certain conditions blue grass will 

 readily establish itself, though live stock should have 

 constant access to the fields where it has been sown. 

 There are other conditions where such treading would 

 injure both the soil and also the grass. But, generally 

 speaking, grazing closely while the plants are young 

 does not injure blue grass as it would other grasses. In 

 fact such close grazing may be advantageous to it by 

 removing shade, as when the seed is sown on the un- 

 broken prairie. Until blue grass becomes well establish- 

 ed on clay soils, it should not be grazed when these are 

 unduly wet, or the soil will poach and will also become 

 impacted to the injury of the grazing. However, when 

 blue grass has covered the soil with a thick sod it may be
