rains, and prevailing low temperatures. The harvest period was 
also generally wet and unfavourable, especially in the later districts. 
The extent of land under wheat was reported to be considerably 
above the average, and shortly before harvest the opinion pre- 
vailed that the crop would be of more than average produc- 
tiveness ; but owing to the unfavourable harvest weather a 
considerable proportion of it was badly got in. 
The following results were obtained in the experimental 
field :—

The quantity of corn per acre, excepting on the unmanured 
plot, was fully equal to, and that of the straw rather over, the 
average of the last 12 of the 20 years. But the crop was unevenly 
and badly ripened, and the weight per bushel was low. The 
season was, indeed, not unfavourable to quantity of produce ; and, 
so far, to a fair average productiveness under the influence of 
liberal manuring ; but it was unfavourable for the full develop- 
ment and the maturation of the grain. 
Fourteenth Season, 1856-7. 
The latter part of October and a great portion of November 
(1856) were fine and seasonable, but the end of November and 
beginning of December were unusually severe : then came a short 
period of very mild weather, with a good deal of rain, followed 
with fine frosty weather ; the quarter having been marked by 
rapid variations of pressure, and extreme changes of temperature.
