898 EXPERIMENT STATION RECORD. 



Wheat in rotation took up much more potash than in continuous cul- 

 ture. As with barley, the greater part of the potash was found in the 

 straw, which also contained the bulk of the carbohydrates in the form 

 of cellulose. 



The conclusion that phosphoric acid is specially concerned in the 

 formation of the nitrogenous bodies and that potash is likewise related 

 to the non-nitrogenous compounds, though regarded as well founded by 

 the authors, otfers only an imperfect explanation of the functions of 

 these mineral constitutents. 



Of all the crops of the four-course rotation the leguminous crops take 

 up the most lime, clover sometimes utilizing more than all the other 

 crops of the rotation taken collectively.

Cotton, K. L. Bennett and G. B. Irby {Arkansas Sta. Bui. 31, pp.23, 24).— Bvief 

 general statements are made as to Egyptian varieties, crosses of American and Egyp- 

 tian varieties, and American varieties. 



Cowpeas, R. L. Bennett and G. B. Irby {Arkansas Sta. Bui. 31, 2)p- 11-16). — Notes 

 on 7 varieties and directions for cultivation are given. The Unknown pea is regarded 

 as the best variety for green manuring and as superior to any of the running varieties 

 for hay. Late planting afforded a growth of vines more nearly upright and a larger 

 yield of peas than early planting.
