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

 but was rather seriously injured by an exceptionally 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 believed that the proportion (d" sound 

 corn obtained by following this plan was greater than it wouh] 

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

 the usual custom. 



On tlu' basis of 100 for nitrate of soda, the ndative standing 

 of the diilerent nitrogen fertilizers and the no-nitrogen })lots as 

 measured by total yield during the })ast season was as fol- 

 lows : —

The relative standing of tlie dilTci-ent niatci'ials a.'^ indicated 

 by total yield for the twenty-two years iliiring which the experi- 

 ment has continued is as follows: —

Tn making up the table on relative standing for the twenty- 

 two years tlie grain only for 1911 was iiudnded, as, owing to 

 the manner in which tlie cro]) was handl<'(1, there liad been 

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

 amount of wdiich was not uniform for the different plots.
