When leaves are of any other hue
than green they are said to be coloured.
This variegation is often considered to :
be a symptom either of tenderness or j
debility; and it is certain, when the :
leaves of a plant become generally j
white, that that individual is seldom i
long-lived. Mr. Knight, however, has i
demonstrated that variegation is not a i
certain indication of a deficiency of
hardihood.
The function of the leaves appear to
be a combination of those of the lungs
and stomach of animals ; they not only
modify the food brought to them from
the roots, so as to fit it for increasing
the sr/e of the parent plant, but they
also absorb nourishment from the at-
mosphere. The sap, after elaboration
in these organs, differs in every plant,
though, as far as experiments have i
been tried, it appears to be nearly the |
.same in all vegetables when it first }
reaches them. The power of a leaf
to generate sap is in proportion to its
area of surface, exposure to the light,
and congenial situation.
The transpiration of plants decreases
with that of the temperature to which
they are exposed, as well as with the
period of their growth. This explains
why the gardener finds that his plants
do not require so much water in cold
weather, nor during the time that
elapses between the fall of their blos-
soms and the ripening of their seed.
During 1 this period they do not tran-
spire more than one half so much as
during the period preceding and at-
tending upon their blooming.
The transpiration takes place from
the upper surface of the leaves. Hence
arises the benefit which plants derive
in rooms, greenhouses, and other con-
fined inclosures, by keeping these
surfaces cleaiised with the sponge and
syringe. Some plants are particularly
sensitive to injury from any check to
their transpiration, among which are the
tea-scented roses ; and it thence arises
that they cannot now be cultivated in
nursery gardens near London, where
they once flourished when that metro-
polis was less extensive. It must be
remembered, however, in using the
sponge and syringe, that the under side
of leaves is also an absorbing surface,
benefited by being kept clean, and by
the application; of moisture.
During the day leaves also absorb
carbonic acid gas, which, they decom-
pose, retaining its carbon and emitting
the greater part of the oxygen that
enters into its composition. In the
night this operation is in a certain
measure reversed, a small quantity of
oxygen being absorbed from the atmo-
sphere, and a yet smaller proportion of
carbonic acid emitted.
Carbonic acid gas in small propor-
tions is essential to the existence of
leaves, yet it only benefits them when
present in quantities not exceeding
one- twelfth of the bulk of the atmo-
sphere in which they are vegetating,
though one-twenty-fifth is a still more
favourable proportion ; and as hotbeds,
heated by fermenting matters, have
rapidly the air within their frames con-
taminated to a much greater extent
than the proportions above named,
thence arises the injury to the plants
they contain from a too long neglected
ventilation. The leaves turn yellow
from the excess of acid, which, they
are unable to digest, and which con-
sequently effects that change of colour
which also occurs in autumn.

LEE-GHEE. Ncphe'lium litchV.
LEEK. A'llium po'rrum. The leek is
a hardy biennial, for although it attains
perfection in size and for culinary pur-
poses the first year, it does not run to
seed until the second, the perfecting of
which it often survives. The whole
plant is eaten, being employed in
soups, &c., and boiled and eaten with
meat.
Varieties. The Musselburyh, and the
large London Leek, which are by far
the best ; the Scotch or Flay, which is
larger and hardier ; and the Flanders.
Sowing. Sow first in the end of
February, a small crop for transplant-
ing in June and July, as well as in
part to remain where sown ; again for
the main crop in the course of March
or early in April ; and lastly, towards
the close of April or beginning of May,
for late transplanting. Sow in drills,
some to remain after thinning ; the
leek, however, is much benefited by
transplanting.
Cultivation. When the plants are
three or four inches in height, hoe
and thin, to two or three inches apart ;
water also, in dry weather, Avill |
strengthen and forward them for
transplanting, when six or eight inches
high. They must be taken away re-
gularly from the seed bed ; the ground
being well watered previously, if not
soft and easily yielding. When thinned
out they may be left to remain in the
seed bed six inches asunder, as they
do not grow so large as the trans-
planted ones, which must be set by the
dibble in rows ten inches apart each
way, nearly down to the leaves, that
the neck, by being covered with the
earth, may be blanched; water in
abundance at the time of planting,
and shorten the long weak leaves, but
leave the roots as uninjured as possi-
ble. By this treatment, and by cutting
off the tops of the leaves about once a
month, as new ones are produced, the
neck swells to a much larger size.
The several sowings above directed
will yield a supply from August until
the following May, when they advance
to seed. A portion should be always
taken up and laid in sand previous to
the ground being locked up by con-
tinued frost, but they will not keep
many days in this situation.
