Asia. Some attention is given to growing it in 

 Germany, the principal source from which comes 

 supplies of seed at the present time. It was intro- 

 duced into Michigan by the experiment station of 

 that State in 1897, and its behavior in several trials 

 made to grow it on sandy and gravelly soils in vari- 

 ous places, has, on the whole, been encouraging. 



Since this variety, like the Turkestan, being con- 

 siderably hardier than common alfalfa, can undoubt- 

 edly be grown further north than the latter, there 

 would seem to be no reasons at the same time why 

 sand lucerne would not grow satisfactorily on 

 sandy soils that lie far south, but this does not seem 

 as yet to have been proved by actual demonstration. 

 It is" possible, therefore, that this plant may render 

 considerable service to areas scattered over consider- 

 able portions of the United States and Canada, in 

 which the soil is light. 



While sand lucerne has higher adaptation than 

 common alfalfa for sandy and gravelly soils, it does 

 not follow that it has equal adaptation for being 

 grown on ordinary alfalfa soils. No advantage, 

 however, would result from growing sand lucerne 

 where common alfalfa will grow equally well, as 

 it is not superior to the latter as a food, if, indeed, 

 it is equal to the same, and there would be a dis- 

 tinct disadvantage in the greater cost of the seed of 

 sand lucerne. 



Sand lucerne is not any more a rotation plant 

 than the common variety. In fact, it is even less 

 so, since it would not be practicable to introduce 

 it into short rotations when grown in northerly lati-
