INTRODUCTION. 81 



'rom 1820 sliipments of clover seed have been made 

 ^om PMladelpliia to Liverpool, and different parts 

 f the United Kingdom. It is quite probable that 

 tie species or variety known in England, as the 

 irge American cow clover was introduced about 

 liis period. There are at present, three distinct 

 pecies of red clover, in England, which are culti- 

 ated by agriculturists, viz: Trifolium Pratense, 

 'rifolium Perrenne and Trifolium Medium. It will 

 le seen by a comparison of their analyses, that there 

 3 not much difference in their nutritive values, 

 'here is however, in their perrennial properties, the 

 wo latter being more permanent or lasting. : ., 



In this country at the present time it may be said 

 hat red clover is simply divided into two classes, 

 he large or mammoth, and the trifolium pratense 

 )r common clover. Parties who have made a spec- 

 ality of growing clover seed for market.in the west- 

 ern part of the state for the past forty years make no 

 3ther distinction than the above. The two kinds 

 ire essentially different, however, in their properties 

 jf grow^th, &c., w^hich will be treated of under its 

 proper head. Of the many substitutes for clover, 

 which are grown in England, such as lucern, sain- 

 foin, burnet, &c., few of tlv3m are cultivated with 

 any degree of success in this country. Although 

 lucern seems to be far better adapted to the climate 

 of this country than that of Britain. Sainfoin I 

 have found to grow well here this spring when other 

 grasses made very little iDrogress. Sainfoin has 

 been cultivated ip England since 1651, and is still 

 in high repute, f Al^-^ke clover is not receiving the 

 attention to which its superior merits entitle it J
