as good prices in the market as timothy hay, although it is 

 more nutritious. There is more danger of its being spoiled by 

 bad management, and horse owners are fearful of injurious 

 results when it is used by careless feeders. Under such unfav- 

 orable conditions it is believed to aggravate the trouble known 

 as heaves in horses. When clover is mixed with timothy in the 

 field the clover will nearly all disappear by the second cutting

 palatable, but the yield per acre is very light. It is not used for 

 hay alone, and even in pastures it is usually mixed with blue- 

 grass, Bermuda grass and other pasture crops. After the plant
