These figures show that the highly beneficial effect of the nitrate 

 of soda, proved by the harvest, manifested itself early in the season 

 and was well sustained until its close. Indeed, the plots which 

 received this fertilizer continued, as a rule, to gain as compared with 

 the nothing plots, throughout the season. July 20th, the corn on the 

 four plots which had received nitrate of soda averaged 10.5 inches 

 taller than that on the two nothing plots. On August 21st, the 

 difference between the same sets of plots was 16.8 inches in favor of 

 the plots which had received nitrate of soda. This result then does 

 not indicate that there has been any great disadvantage in applying 

 this fertilizer all at one time, just before planting the seed ; and it 

 should be remembered that this soil is a " light sandy " one, and that 

 there was a full average amount of rain during June, July and 

 August.
