fourth being cowpeas. This is at the rate of 4.() tons of the mixture 

 per acre. 



In an adjacent one-tenth acre plat Johnson grass and cowpeas were 

 seeded at the same rate; that is, 2 pounds of Johnson grass and 3 

 pounds of Early Black cowpeas in place of Sudan grass (fig. 5). The 

 yield of the mixture was 561 pounds of air-dry hay, or 2.8 tons per 

 acre. 



A similar mixture of Sudan grass and Arlington soy beans, a twin- 

 ing variety, was sown the same date, using 3 pounds of soy beans and 

 2 pounds of Sudan grass. About one-fourth of the mixture was soy 

 beans, which twined about the grass to a height of 4 to 6 feet. When

cut on September 6 the Sudan grass was in bloom and the soy-bean 

 pods w^ere about half grown. 



This mixture cured more readily than the cowpea mixture and was 

 superior in physical quality. The yield was 888 pounds of cured hay, 

 or at the rate of 4.-1: tons per acre.

TESTS AT MISCELLANEOUS EXPERIMENT STATIONS. 



TEXAS. 



At the San Antonio (Tex.) Field Station Mr. S. H. Hastings 

 tested Sudan grass in 1911 and 1912 and reported as follows: 



From the growth of the plat tested in 1911 this apijears to be the most prom- 

 ising grass that has been grown at the experiment farm. Two plats were
