This experimeut was made on a white, sandy soil, 

 poorer than that used in the last mentioned experiment. 



In th(^ late spring and early summer of 1899 velvet 

 beans hiid been planted in drills on certain plots and 

 begjz:ar weed had been sown broadcast on others. The beg- 

 gar weed and a portion of the velvet beans was used 

 exclusively for fertilizer. On other plots velvet beans 

 Avere cut, thus leaving only the stubble as fertilizer for 

 corn. 



"These various fertilizing materials were all plowed 

 under March 31, 1900, and Mosby corn planted April 

 5, using per acre 240 pounds of acid phosphate and 40 

 IKninds of muriate of potash.
