 tirely satisfactory srrowth. 



Noyember 9 all plots were plowed, turning under 

 either yolunteer grass and rag weeds, or cowpea yines, 

 or yelyet bean yines, or cowpea stubble, or yelyet bean 

 stubble. The plowing was poorly done with a one- 

 horse turn plow and in sowing the wheat a few days 

 later some of the yelyet bean vines were pulled ay. The 

 wheat receiyed only mineral fertilizers, and, indeed, 

 practically no nitrogen had been applied to these plots 

 for three years. 



The yields of wheat in 1900 were as follows : 



Bushels of icheat per acre after leguminous and non- 

 leguminous crops : 



Both the stubble and the vines of the legumes prac- 

 tically trebled the yield obtained on the plots where no 

 le«Time had orown. The stubble was at least as effect- 

 ive as the vines, pointing to the greater economy of uti- 

 lizing the vines for hay or pasturage. 



June 19, 1900, all these plots were planted with Mos- 

 by corn, fertilized only Avith phosphate and muriate of 

 potash. The crop was a failure on all plots, the yield 

 of cured fodder corn ranging from 1,510 to 2,200 pounds 

 per acre, the plots where vines had been plowed in the 

 previous fall showing no superiority over the stubble 

 plots, and very little increase as compared with the 

 plot where no legume had grown. It is impossible to 

 ascertain whether the failure with corn was due to the
