 beans, jjotatoes, oats and peas, corn, clover for four years and 

 corn. 



The corn crop of the past season made an excellent growth, 

 but was rather seriously injured by an excejitionally early and 

 severe frost on September 13. So serious was the injury that 

 it was deemed best to allow the crop to stand until the ears were 

 thoroughly dry. It is Ixdieved that the jiroportion of sound 

 corn obtained by following this plan was greater than it would 

 have been had the crop been cut and shocked in accordance with 

 the usual custom. 



On the basis of 100 for nitrate of soda, the relative standing 

 of the different nitrogen fertilizers and the no-nitrogen plots as 

 measured by total yield during the past season was as fol- 

 lows : — 



Per Cent. 



Grain on Cob.

 Barnyard manure, 

 Sulfate of ammonia, 

 Dried blood.

The I'elative standiiig of the diilVreiit maierials as indicated 

 by total yield for the twenty-two years during which the exjieri- 

 ment lias continued is as follows : — 



Per Cent. 



Nitrate of soda, lOO.OU 



Barnyard manure, ......... 94.20 



Dried blood, 92.80 



Sulfate of ammonia, ......... 87.53 



No nitrogen, .......... 73.04 



In making u]) the table on relative standing for the twenty- 

 two years the grain only for 1011 w^as included, as, owing to 

 the manner in which the crop was handled, there had been 

 breakage and waste from the frost-bitten stalks and leaves, the 

 amount of which was not uniform for the different plots.
