The variety of the preceding table is described as making 

 but little vine, and is considered less valuable than the 

 " Clay " variety. It made a dense foliaceous growth, fully 

 equal to the latter in size. Neither of them produced seeds. 



COW PEA. 

 Variety : WnipPOORWiLL. 



[Raised on Plats of Station, as Mixed Crop, with Oats. Collected Aug. 1, 1883.] 



The analysis was made from the pea vines raised with the 

 oats ; the analysis of the latter has been reported in Bulletin 

 5 (No. 102). This course of separate analj^sis was adopted 

 on account of the uneven distribution of both plants. The 

 mixed crop was, on the first of August, in excellent condi- 

 tion for green fodder or hay. An experiment with rye 

 failed, on account of a bad quality of r3^e. Assuming the 

 mixed crop of peas and oats to consist of three times as 

 much oats as peas, the nutritive ratio of the mixture would 

 be 1:12. In case of two parts of oats and one of cow 

 peas, the ratio would 1 : 10, and in case of even quantities 

 of both plants, the ratio would be 1 : 8.7. Raised in con- 

 nection with rye the nutritive value of the mixed crop would 

 be still hiijher. AVithin three months' time, a fodder can 

 be raised f'iUi/ equal, if not decidedly superior in nutri- 

 tive value, to our best English grasses.
