equal conditions of manuring ; but tho deficiency was propor- 
tionally less with the heavier dressings. The quantity of straw 
was also much below the average, though not quite so much so 
as that of the grain; but, as in the case of the latter, it was pro- 
portionally less deficient with the heavier manuring. The.quality 
of grain, as indicated by the weight per bushel of the dressed 
corn, was throughout extremely low ; in fact, lower than in any 
other year of the 20, excepting 1853. 
The following abstract shows the character of the experimental 
crops : —

The experimental crop of the extraordinarily wet and cold 
growing and ripening season of 1860 was, therefore, in every 
respect very inferior, and much below the average. In yield of 
grain it was only about equal in quantity, and it was inferior in 
quality, to that of 1852, and inferior to it also in produce of 
straw. But it was superior both in quantity and quality of grain 
to the miserable crop of 1853, though even inferior to it in 
weight of straw. 
Eighteenth Season, 1860-61. 
October (1860) was, upon the whole, seasonable; November 
was very cold, with a good deal of rain ; the beginning of De- 
cember was mild, but the remainder of the month, and a great
