CLOVEKS. 221 



Mammoth clover usually yields but one crop in a 

 season. It produces seed plentifully in this country. 

 The seed can not be distinguished from that of me- 

 dium red clover. One crop of mammoth clover may 

 not yield as much as two crops of medium clover. 

 The one crop of the former may be more economical 

 than the two crops of the latter. 



Mammoth clover grows rather coarse on rich soils. 

 The quality of the hay is in such cases not so good as 

 that of medium red clover. It is best adapted to 

 relatively poor soils. Its deep roots and coarse 

 growth gives it a large manurial value. 



White Clover ( TrifoUum reperis) holds the 

 same relation to Kentucky blue grass as red clover 

 does to timothy. It is suitable for pasture only. For 

 pastui'e it is, in connection with Kentucky blue grass, 

 unexcelled. It is not largely sown but finds its way 

 into pastures which are suited to it. It is very un- 

 even in its distribution, even in the same field , and 

 grows very unequally in different seasons. It needs 

 warmth and moisture but stands drought better than 

 red clover. 



It seeds freely. The seed may remain in the soil 

 several years. The seed is supposed to make horses 

 slobber on account of their acid nature, a character- 

 istic common to all clover seeas. There are about 

 twice as many seeds in a pound as of red clover. . It 

 roots readily from its creeping stems. It is perennial. 

 It is frequently called Dutch clover because it was 

 first brought into cultivation in the Netherlands. 



Alsike or Swedish Clover [TrifoUum hybri- 

 dum) is a finer, smaller clover than medium red clo- 

 ver, with blossoms of small reddish white heads. In
