SOILS. GENERAL CONSIDERATIONS. 



103 



Evidently, in making a choice of land for beet cul- 

 ture, if we take these as a basis, or a series of others 

 having given good results, we cannot be far from the 

 truth, but it would not necessarily follow that because 

 the ones in question contained more of a given chemi- 

 cal and less of another that little or no sugar could be 

 expected ; for example, when we compare the soils of 

 Prussia, apparently heavy, and those of France.
