nitrogen, nitrate of soda is applied at the rate of 250 pounds 

 per acre, except on the pk)ts where nitrate of potash is the 

 source of the potash applied ; here a suitable reduction in 

 the quantity of nitrate of soda is made, on account of the 

 nitrate nitrogen furnished by the })otash salt. The principal 

 source of phosphoric acid on these plots is acid phosphate, 

 applied at the rate of oGO pounds per acre to all. Tankage 

 at the rate of 270 pounds per acre is applied to all plots as 

 a source of less immediately available nitrogen and phos- 

 phoric acid. The crops grown in this experiment in the 

 order of succession are as follows : 1898, Medium Green 

 soy beans; 1899, Beauty of Hebron potatoes; 1900, Fott- 

 ler's Brunswick cabbage. Medium Green soy beans, Black 

 coAV pea, Wonderful cow pea; 1901, Turkish Red wheat, 

 Medium Red clover ; Rural Thoroughbred, Leaming Field, 

 Boston Market and Eureka corn ; 1902, Medium Red clover ; 

 1903, Medium Red clover. 



During the past season the crops grown in the field were 

 as follows : cabbages on sixteen plots, two series of eight 

 each ; Sibley's Pride of the North corn on sixteen plots, 

 two series ; and Leaming Field corn for ensilage on eight 

 plots. The season was unfavorable to full maturity for the 

 cabbage crop, for reasons which have been alluded to in dis- 

 cussing results on fields B and C. For the same reasons, 

 and also because of the excessive rains at the season of 

 l)lanting, the season was highly unfavorable to the corn crop. 

 Defective germination, owing to the excessive rains, pro- 

 duced an uneven stand of plants in the areas devoted to 

 corn. For the reasons indicated, it does not seem worth 

 while to publish the results in full detail, and averages only 



will be ijiven. 



These for the cabbages are as follows
