performing this work, it is proper to
un-nail or loosen a chief part of the
branches, particularly of peaches, nec-
tarines, apricots, vines, and other trees
requiring an annual supply of young

PRU [ 7
PKU'NUS. Plum. (From prune, a
plum. Nat. ord., Ahruntdn-orts [Dru-
pacese]. Linn., 12-Icosandria l-M<to-
gj/nia.)
Hardy deciduous trees, white-flowered, and
blooming in April. Seeds for varieties and
stocks, suckers for grafting and budding ; deep
loamy soil, if calcareous all the better. For
the cultivated Plum, the Muscle and St. Julian
stocks are generally used. When dwarfs are
desired, the Myrobalan Plum is preferred. To
obtain stocks in great plenty, the long shoots
from the stools of last year's growth are laid
down in the spring their full length, and co-
vered with soil ; almost every bud sends up a
shoot, and roots are formed nearly cotempora-
neously. In autumn, the shoot laid down is
cut off, and then cut into as many pieces as
there are young shoots and roots. See Plum.

PSY'LLA. The Chermes, is allied to
the Aphis. P. pyri, Pear cheriues,
appears in May, not unlike a large
aphis, crimson-coloured, shaded with
black. Mr. Kollar says, when pairing
is over, the female lays her eggs in
great numbers near each other, on the
young leaves and blossoms, or on the
newly formed fruit and shoots. They
are of a longish shape, and yellow ;
and, without a magnifying glass, they
resemble the pollen of flowers. They
are called either nymphs or larvae in
this state (according to the extent of
their development) ; and, like their
parents, have their mouth in the
breast. After a few days, they change
their skins, and become darker, and
somewhat reddish on the breast, and
rather resemble bugs than plant-lice,
having the extreme point of the body
somewhat broad, and beset with bris-
tles. After changing their skins, they
leave the leaves, blossoms, and fruit,
and proceed more downwards to the
bearing wood and the shoots of last
year, on which they fix themselves se-
curely, one after the other, in rows,
and remain there till their last trans-
formation.
When the nymphs have moulted for
the last time, and have attained their
full size, the body swells out by de-
grees, and becomes cylindrical. They
then leave their associates, and before
they lay aside their nymph -like cover-
ing, they search out a leaf to which
they fasten themselves firmly, and ap-
pear as if they were lifeless. After a
"few minutes, the skin splits on the
upper part of the covering, anil a
insect proceeds from it. It is of a
pleasant green colour, with red eyes,
and snow-white wings. It very much
resembles its parents in spring, even
in the colour. After a few days, this
chermes has assumed the colours of
the perfect insect ; the head, collar,
and thorax, are of an orange colour,
and only the abdomen retains its green
hue. It now flies away from the place
of its birth to enjoy the open air.
P. mail. Apple Chermes. This, ac-
cording to the same author, appears in
June. In September, they pair, and
lay their eggs, which are white, and
pointed at both ends, a line-and-a-half
long, and the fourth-of-a-line thick,
and become yellow before the young-
escapes. The apple chermes lays its
eggs in different places of the twigs of
an apple-tree ; usually, however, in the
furrows of the knots, and sometimes in
a very regular manner. The larvce
are scarcely escaped from the egg, in
the open air, when they hasten to
the nearest bud, and begin to gnaw its
scales. On the second day after their
birth, they cast their first skin, after
which they appear nearly of their
former shape and colour. The second
; changing of the skin can sometimes be
] scarcely seen at all, because the larva
not only puts out a thicker string with
' the tubercle, but also an immense num-
ber of very fine entangled threads or
small hairs, which it turns upwards
over its back, a'Ad with them entirely
covers its body and head. In sunshine,
these strings look transparent, as if
they were made of glass, and become
of a greenish variable colour. Under
this screen the chermes are secured
from every attack of other insects ; for
no ants, mites, or bugs, can disturb
them in their fortification, or consume
them as their prey. After changing the
second skin, the young assume a dif-
ferent colour and fonn ; they now be-
come light green all over, the abdomen
much broader than the thorax, and
on the side of the latter, rudiments
of the wings are distinctly seen. The
third time of changing the skin comes
on in about eight days, sometimes
sooner and sometimes later, according
PSY [ ",
to the weather. After this skin, the wing
rudiments very distinctly make their
appearance, and become larger and
whiter the nearer the insect approaches
to the perfect state. The body is also
of a light green, and the larvae have
black eyes, and blackish antennas. At
last the time arrives when the insect
assumes the perfect state ; it then re-
tires to a part of the leaf which it had
selected, and after having firmly fixed
itself there, the back splits open, and
the beautiful winged chermes appears
from the nymph. The back of the
thorax is of a light green, the abdo-
men is marked with yellow rings, and
the membranous wings with strongly
marked snow-white veins.
P. cratcegi infests the camellia.
P.ficus and P. rasce, are respectively
on the fig and rose-trees. All the
species are destroyed by syringing with
tobacco-water, until the insects are
dead, and then syringing with water
only. See Aphis.

PU'NICA. Pomegranate. (From pu-

Nat. ord., MyrtleUooms [Myrtaceee].
Linn., 12-Icosandria \-Monogynia.}
Deciduous trees, all blooming in August.
Cuttings of the shoots and roots ; layers and
grafting ; any light rich soil. It flourishes
against a wall, but in such places the twigs
must be encouraged to grow, or there will be
few flowers. The double kinds grafted on the
single, and grown in rich loam, become nice
flowering plants, as the plants do not grow so
vigorous as on their own roots, but flower much
longer. Nana requires the stove.

monia.)
Hardy evergreen shrub. Cuttings of young
shoots, in sand, under a hand-light, in early
summer ; also by seeds, treated as rose seeds ;
sandy poor soil.

A light rich soil they thrive in most,
and they must have a warm situation,
as a south border. Sow in February
and early in March, in a moderate
hotbed, to remain where sown ; and at
the close of March, and once monthly,
during April, May, and the summer
months until the end of August, in the
open ground.
Sow in drills six inches apart, very
thin, and not more than a quarter -of-
an-inch deep. Keep the seedlings j
clear of weeds, and thin to six or eight i
inches asunder, In dry weather, water ;
moderately two or three times a-week.
In general, they are ready for ga
thering from in six weeks after sowing, ;
the young shoots being made use of ;
from two to five inches in length, and
the plants branch out again.
The hotbed crops require the air to
be admitted as freely as the weather
permits, the temperature ranging be-
tween 50 and 75.
To obtain Seed. A few of the earliest
border-raised plants must be left un-
gathered from ; the strongest and
largest leaved being selected. They
must be cut immediately the seed is
ripe, laid on a cloth, and when perfectly
dry, thrashed, and the refuse is best
separated by means of a very fine sieve.
