EXPERIMENTS IN DEEP PLoUGHING.
Al late meeting of the Highland Agri-
cultural Society Of Scotland, Mr.. Grdwood
read a report of the experiments in deep
ploughiug, mode by Mr.. Wilson Of East.

The farm on which Mr.. Wilson's expor.
imenis were mnde, is nearly level, the soil
varying from gravelly earth 10 tenacious
clay. il had for many years been plowcd
from to 6 inches deep, and at that depth
hard crust or pan had formed, which as
almost impervlous 10 water.
The first field experimental upon, con.
sssd Of 3 acres, partly heavy, on clay

4 depth of or I inches was first taken
with the common pl0w, IN October and No

subsoil pillow TO un additional depth of Z or

usual way.

through the crust or pan, or that portion
where the subsoil pillow bad been. The
whole Geld was equally mnnufed with a
moderate supply OF iaFm.yard dung aud

The appearance of the whole crop was
similar till August, when that portion OF II
in the sub soied land took the lead, and tho
produce per acre where sub. soled was 26
tons II cwi., and where plowcd IN the old
way, 20 tons ! cwt.
The second experiment was made 90 a
field of deep EARTH inclined TO sand, on a
subsoil Of sandy clay. Two acres were
sub.soiled - inches deep, two we're pio~-
ed 6 or : inches, and two ridges we're
trench. plowed l3 inches. The field was
cross plowed in the spring, MANFRED IN the
drill, and plaaied with potatoes, the crop
was lifted towards the end Of October, when
the quantity yielded by each portion per
acre, was as follows

Another experiment was made on a field
intended for barley, after potatoes. The
barley was sown about the lst Of April ;
the sub solled portion kept the lead through.
out the crop was cut on the 29I Of Sep.

on the sub. sorlcd land was qrs. 3 bushels
barley, aud 3G4 c~ls Of straw, aud on tho
plowej ore. ! bushels, 3 pecks, aud .

Another experiment was made when

be advantageous 10 solls OF deep nature,
but injurious 10 those which are thin, with

great variety Of soils will derive much bcn.

Mr.. GlIdwood remarked, lhl, he agreed
with Mr. Wilson asto the soils winch -ho uId
be deep plowed aud sub. soded, aud called
attention to The great crop Of barley obtain.
