76 THE BOOK OF USEFUL PLANTS 



Sand lucern is proving just the thing for light, 

 sandy soil in the north central states. 



The growing popularity of alfalfa in Kansas is 

 shown by the fact that in 1891 the crop measured 

 34,000 acres. In 1907 it was 743,000 acres. The 

 prejudice of farmers is strong against a "new 

 thing." But even prejudice must surrender when 

 the new plant multiplies the farm income, and 

 at the same time improves the land.
