The _ninth_ season (1851-2), was unusually cold in June and wet in
August. It will be seen that the wheat, both in quantity and quality, is
the poorest since the commencement of the experiments. The unmanured
plot gave less than 14 bushels of dressed grain per acre; the plot with
barn-yard manure, less than 28 bushels, and the best yield in the whole
series was not quite 29 bushels per acre, and only weighed 55 lbs. per
bushel. On the same plot, the year before, with precisely the same
manure, the yield was nearly 37 bushels per acre, and the weight per
bushel, 63-1/2 lbs. So much for a favorable and an unfavorable season.

The _tenth_ season (1852-3), was still more unfavorable. The autumn of
1852 was so wet that it was impossible to work the land and sow the
wheat until the 16th of March 1853.

You will see that the produce on the unmanured plot was less than 6
bushels per acre. With barn-yard manure, 19 bushels, and with a heavy
dressing of ammonia-salts and minerals, not quite 26 bushels per acre.
With a heavy dressing of superphosphate,
