crop, in this part of our experimental field, was 101.5 feet 

 long and 80 feet wide ; it yielded 3,765 pounds of green fod- 

 der, with an average of from 12 to 18 per cent, of dry vege- 

 table matter. The rate of production per acre, calculated 

 on the basis of our own observation, would be 9| tons of 

 srreen fodder. A few weeks more of OTowth would have 

 materially increased the yield. The course adopted in our 

 feeding experiment obliged us to use the Southern cow pea, 

 as the serradella was not yet far enough advanced in growth. 

 Southern obseiwers obtain from 20 to 25 tons of green crop 

 per acre. The cutting of the pea vines for fodder began as 

 early as Aug. 1, and lasted until Aug. 23. A new growth 

 had started from the roots again Aug. 25 ; it proved, how- 

 ever, of but little value for feeding purposes, on account of 

 the lateness of the season.
