It was a poor year for the wheat-grower, and that, whether he manured
excessively, liberally, moderately, or not at all.
“I do not quite see that,” said the Deacon, “the farm-yard manure gave
an _increase_ of nearly 20 bushels per acre. And the quality of the
grain must have been much better, as it weighed 3½ lbs. per bushel more
than the plot unmanured. If the wheat doubled in price, as it ought to
do in such a poor year, I do not see but that the good farmer who had in
previous years made his land rich, would come out ahead.”
“Good for the Deacon,” said I. “‘Is Saul also among the prophets?’” If
the Deacon continues to study these experiments much longer, we shall
have him advocating chemical manures and high farming!
The _eighteenth_ season (1860-1,) gave less than 11½ bushels per acre on
the unmanured plot; and nearly 35 bushels on the manured plot.
The mixed mineral manures, gave nearly 15½ bushels.

The _nineteenth_ season (1861-2,) gave 16 bushels per acre on the
unmanured plot, and over 38¼ bushels on the plot manured with farm-yard
manure.
Mixed mineral manures, gave nearly 18 bushels per acre.

The _twentieth_ season (1862-3), gave 17¼ bushels on the unmanured plot,
and 44 bushels per acre on the manured plot.
Mixed mineral manures alone gave 19¾ bushels per acre.

When we consider that this is the twentieth wheat-crop in succession on
the same land, these figures are certainly remarkable.
“They are so,” said the Deacon, “and what to me is the most surprising
thing about the whole matter is, that the plot which has had no manure
of any kind for 25 years, and has grown 20 wheat-crops in 20 successive
years, should still produce a crop of wheat of 17¼ bushels per acre.
Many of our farmers do not average 10 bushels per acre. Mr. Lawes must
either have very good land, or else the climate of England is better
adapted for wheat-growing than Western New York.”
