a strain that he had thus selected. Ordinary crimson 

 clover, however, usually winter-kills in the states north 

 of New Jersey and west of the Alleghany Mountains. 



Crimson clover has been successfully grown in Georgia, 

 Alabama, Mississippi and Tennessee, but the prevailing 

 dry autumns. in these, states make it difficult to secure a 

 catch. In the moister region near the Gulf of Mexico, it 

 succeeds well, but is little used. 



In Oregon, Washington and British Columbia west of 

 the Cascade Mountains, the conditions are also very favor- 

 able to crimson clover, but it has never been much used. 



For fall sowing the important requisites are a mild winter 

 climate and comparatively frequent rainfalls in late sum- 

 mer and early fall so that the plants can get well started. 



As a spring-sown crop, crimson clover has succeeded 

 in Michigan and North Dakota, but it is doubtful if it 

 can compete with red and alsike clover used in this manner. 



Crimson clover shows no very marked soil preferences, 

 succeeding both on sandy and clayey soils, whether cal- 

 careous or not, so long as they are well drained. It does 

 not succeed well on poor sandy soils and demands a good 

 humus content for its best development. On muck soils 

 it is said not to succeed well. 



Crimson clover is well adapted to withstand shade, 

 and so is often sown in orchards and with other crops. 



Crimson clover apparently never has been troubled in 

 America by " clover sickness," it having been sown on 

 some farms continuously for at least ten years. Werner 

 writes that in Germany it should not be again sown on the 

 same ground until four to six years have elapsed. 



515. Importance. Crimson clover is grown in the 

 United States mainly in New Jersey, Delaware, Maryland 

 and Virginia, but its culture is increasing in the Carolinas.
