needing humus sadly. It has failed in countless in- 

 stances because of lack of inoculation. If one wishes 

 to grow it he should either inoculate with soil from 

 some successful crimson clover field or should per- 

 sist year after year in growing it on the same soil 

 till at last the inoculation comes. There seems 

 a wild clover along the Atlantic Coast that carries 

 the same bacteria as crimson clover but this is not

 territory than is now known or supposed.

 will bear seed when only just above the earth.
