, it
suffered also much from rust. Allowing for the destruction
occasioned by the birds, the crop was estimated at:

41 1/4 bushels in patch No. 1,
36 " " No. 2,
41 1/4 " " No. 3,

and in that part of No. 3 which was also covered with guano, it
reached by actual weight (not by estimate), 53 bushels of 60 lbs.
to the acre. Those patches in Nos. 1 and 2 which had guano put on
them, suffered so much from the depredations of the birds, that no
account was taken of them separately. The crop was cleared off the
land, which was cleaned, and again sowed with wheat on 3rd
October, 1843. It was drilled in rows seven inches apart, and at
the rate of 2 1/2 bushels to the acre. It is to the results of
this crop that I now wish to call your attention. Before sowing,
the land was subsoiled to the depth of from 14 to 16 inches;
except a strip of about 10 feet in width, down the middle of the
field, which was left untouched for the purpose of determining
what were the advantages derived from subsoiling. If the advantage
was merely that of thorough draining (for the field had not been
thoroughly drained previous to the subsoiling), it was thought
probable that this strip of 10 feet wide would be drained by the
subsoiling on each side of it; but if, in addition to this, the
wheat plant derived more nourishment by striking its root deeper
into the soil, where that was loosened by the subsoil plough, the
crop ought to be better in the subsoiled than in the unsubsoiled
part. The field runs over the ridge of a hill, and upon that ridge
the soil is so poor and thin, that it was deemed expedient to give
it a slight dressing of coal-ashes and night-soil, from an idea
that the plant would scarcely survive the winter unless some
stimulus were applied there; but the ashes contained little
manure, and were only applied to the worst part of the field,
covering about one-third of its surface. The wheat was Spalding's
Prolific; it came up evenly and well all over the field. It was
hand-sowed with lime early in February to the extent of about 24
cwt. of dry lime on the acre. In order to ascertain the value of
lime, and the proper quantity, I had the field uniformly covered
with it, except one land, which was left entirely without, and the
headlands, which had one three, the other six times as much lime
put upon them as any other part. The field was also dressed with a
chemical manure of the following ingredients on th
