large produce without manure, and by mineral manure alone, 
in the first year, shows that there was a quantity of un- 
• exhausted nitrogen from previous manuring available within 
the soil. The larger produce by ammonia-salts alone in the 
first than over the 20 seasons shows, in like manner, a com- 
parative exhaustion of available mineral constituents in the 
later years. On the other hand, in the case of the farmyard 
manure, and the artificial manures in which there was annually 
supplied an abundance of mineral constituents as well as 
ammonia, or nitrogen in some form, the average produce of the 
20 years considerably exceeded that of the first year. Part 
of this latter result is doubtless due to accumulation from 
year to year ; but no doubt it is also in great measure due to the 
comparatively defective productive characters of the first season. 
This conclusion is confirmed by the fact that, the quality of 
the produce, as indicated by the weight per bushel, was, both 
from the deficiently and from the liberally manured plots, 
considerably belov/ the average. The proportion of corn to straw" 
was also in most cases below the average. 
The results obtained in the experimental field are accordant, 
therefore, with those over a considerable area of the country, in 
showing that the variable, but upon the whole wet and cold 
season of 1 852, was unfavourable to the barley crop, and 
especially so in point of quality. 
Second Season, 1853. 
Up to the middle of January, the winter of 1852-3 was, upon 
the whole, very unseasonably warm and wet ; the rest of January, 
February, and March, were very cold, with a good deal of east
