and Geoftroy st. Pilaire, is that Of
ccnpensation of growth, whereby,
when much organized matter is used
In building up some one'part, other
parts become starved. In the corn
plant Injection Of this law can be
fsdily perceived, for, II we plant our
sssdi in osermanured soil, there il such
. vigorous development Of leaf that
the development Of the grain is in
terfered with. II, however, in this
rich soil the leaf growth Of the plant
DO checked, the nutriment which, in
the over-growth Of the plant, would
be expended in leaf is diverted to the
formation Of seed, and an abundant
crop is.the result. This idea is at the
foundation Of the principle Of cultiva-
ton in ito effect.on the plant, and
forms the basis Of the theory Of root
Framing agricultural plants; FIRST
snunciated as q distinct theory by
ursslves. When the land is rich and
moist but not wet, and the tempera-
ture warm; then the use Of the cult
vssor. running il deeply and as close
to the plant as possible, sewers the
roots and checks the leaf growth Of
the plant, thus increasing the tenden-
ey to grain bearing. Careful exper-
iment prove that plants treated in ac-
cordance with tho theory show in-
creased fruitfulness; that plants on
over-rich land without cultivation
bear but few good ears; and that
plants under like gconditions as the
latter named, if their leaf growth be
checked in any way, but especially by
interference with the roots, become
fruitful. Trials, whenever made in
accordance with this theory, have, 80
far az we have learned, resulted in
increasedscrops; while on the other
hand, deep cultivation, when done
Northumberland to the condition of
the soil and the crop, have been re-
ported to US as failures. We shall
therefore lay down q few rules, as de-
rived from experiment, theory and
practice, the one correcting the other,
and which seem worthy Of conf
dence.
All corn crops seem benefited by
the ordinary Guilty ation Of the farm
in general, is shallow rather than
deep. All culture after the blooming
Of the plant seems advantageous;
and, indeed, in general, the plant is
now 50 large, and the other farm du,
ties 90 pressing, that it is seldom
practiced. The roason for the injury
seem to be that so soon az the forces
or tho plant are directed toward the
grain growing functions . check to
the plant is not advisable, but all the
stimulation possible to the growth,
now diverted in the profitable direc-
ton, should be sought. Cultivation
seems to produce the largest benefit
upon land in good condition, and
whore the plant is growing rapidly.
Hence, deep culture should not be
practiced except where..there is a rap
id growth, unless, rarely to pulver-
ize q soil which has become unduly
hardened. In times Of drouth cult
vate shallow, in order to form q fine
mulch Of soil, which shall conserve
the moisture in the land. But when
the season is moist and warm cult
vate deep. m order to dry the soil and
check too vigorous leaf-growth
When the season is moist and colo
cultivate shallow, 30 that evaporation
shall not chill the land more than ii
possible, and that the surface soil may
more quickly warm; for under these
circumstances the corn roots arr
more superficial than otherwise
When the field is ~unfertile, then cult
vate shallow, as it is not desirable tc
force the plant to form more ears thar
the nourishment in the land can de-
velop.1 The larger the plant, up to
the perod Of bloom, the more is q
thorough cultivation indicated, and
the more beneficial it becomes. But
30 soon as the tassels appear, keep al
implements out Of the field. A gen.
81 iule, which embraces abont all, is
to watch the plant, and use judgment.
