CRIMSON CLOVER 373 



plant a crop of cotton or corn. It adds a large quantity of 

 vegetable matter to the soil and also materially increases 

 the supply of nitrogen. It is seldom used as a pasture crop, 

 but is occasionally cut for hay. The hairy stems and leaves 

 are somewhat objectionable, and when the hay forms a large 

 part or all of the ration of an animal, "hair balls" are some- 

 times formed in the stomach, giving considerable trouble.
