198 CLOVERS 



grown under the most favorable conditions which 

 Europe furnishes. 



This plant is better adapted to a cool and humid 

 climate than to one hot and dry. It is even more 

 hardy than medium red clover, in the sense of en- 

 during cold, and will live under conditions of climate 

 so austere as to be fatal to red clover. It may, there- 

 fore, be grown further north than medium red clo- 

 ver, and under conditions so exposed as to cause 

 medium red clover to fail. But it does not succeed 

 quite so well as the former toward the southerly 

 limit of the successful production of medium red 

 clover; hence, the limit of production in the semi- 

 arid belt ceases sooner than in the case of the other 

 variety. The best climatic conditions for growing 

 it are found not far from the boundary line between 

 the United States and Canada, and in the vicinity 

 of the Atlantic and Pacific oceans and the Great 

 Lakes. 



In the United States the best crops are grown in 

 the States which border on Canada, and in these 

 the highest adaptation, climate and soil considered, 

 is found in Michigan, Wisconsin and Northeastern 

 Minnesota. But in New York the adaptation is also 

 high, and also in certain parts of Montana, Idaho 

 and Washington. Good crops may also be grown 

 in nearly all the second tier of States that lie south- 

 ward from the Canadian boundary. The exceptions 

 are those embraced in the semi-arid belt. Further 

 south than the second tier of States to which refer- 

 ence has just been made, the successful growth of 

 alsike generally lessens, and yet in parts of these
