corn was rather higher than in any other year of the experiments ; 
and the proportion of com to straw was much above the average, 
being about the same as in 1846 and 1857, the years of highest 
yield of corn in proportion to straw throughout the 20 years, 1844 
excepted, when it was unusually high, but when, in these experi- 
ments, the total amount of produce was very small.

The season of 1849 seems to have been particularly favourable 
£or the action of nitrogenous manures; there* being comparatively 
little deficiency where the ammonia-salts were used alone, as 
compared with the result with the same amount in conjunction 
with mineral manure ; and the excessive amounts of ammonia 
gave proportionally larger amounts of increase than in most of 
the other seasons. 
Seventh Season, 1849-50. 
The autumn of 1849 was generally favourable for getting in 
the seed. In the early part of December, and the latter part of 
January (1850) there was a good deal of rain, and, intermediately, 
pretty continued frost. February was fine and mild ; March 
fine, but very cold ; April very fine and seasonable until the last 
Aveek, when it was much colder ; and May cold and wet in the 
early part, but seasonable afterwards. June, July, August, and 
September, were almost throughout unseasonably cold ; and there 
were occasional heavy rains in June and July, but during 
August, and the greater part of September, but little rain fell.
