" P^eonia. — The Chinese shrubby species 
are increased by layers, by cuttings, by graft- 
ing them on roots of one another. They are 
hardy enough to stand our winters in a shel- 
tered spot, but, as they flower so early in the 
season, their flowers are apt to be cut off by 
late frosts. When grown in pots, they may be 
kept most of the year in a cold pit, and brought 
into the gi'een-house to perfect their flowers, 
which are magnificent. Any rich, good soil 
suits them to grow in. 
" Cineraria. — Many of the species produce 
seeds, from which of late years some fine 
hybrids have been obtained. They all strike 
very readily by cuttings, and also by dividing 
at the root. No plants are more easily culti- 
vated than these. 
" EcHiira. — The'Cape species of this genus 
are splendid-flowering plants, but too much 
neglected in modei*n cultivation. They ripen 
seeds, and are easily increased by cuttings, 
planted in sand, and placed in a cool situation. 
Peat and loam is a good soil for them. 
" Anagallis. — This pretty little genus is 
readily increased by cuttings, which strike in 
sand. The plants prefer light, sandy loam 
' and peat. 
" Lechenatjltia. — The young tips of the 
shoots, taken off about an inch long, and 
planted in sand, covered with a bell-glass, and 
placed in a dry cool place, strike freely. The 
grown-up plants prefer peat and loam to grow 
in, but by far the greater portion of the former. 
" Psoralea. — A genus easily cultivated : 
the young or the half-ripened shoots root 
freely, and seeds are also frequently produced. 
They thrive well in a peat and loam soil. 
" Coronilla. — This genus is readily in- 
creased by cuttings of the young wood, planted 
in sand, left uncovered, and placed in a close 
heat. Peat and loam, of each equal parts, is a 
good soil for them. 
" In regard to the propagation of green- 
house climbers, viz. Passiflora, Jasminum, 
Hibbertia, Convolvulus, Sollya, Billardiera, 
Dolichos, Bignonia, &c, they strike by cuttings 
in the same way as directed for the plants above. 
They require a rich soil and considerable space 
for their roots to spread in, as the object is to 
make them grow luxuriantly, and flower abun- 
dantly."— Pp. 210—218. 
We now come to the Conservatory, and here 
there is great variety of form, fashion, and 
of plants to fill them. No two persons 
manage a conservatory alike, and we remem- 
ber to have been sadly disappointed on enter- 
ing some of the most costly in the kingdom, 
to find the inside wretchedly planted or fur- 
nished, or both. There is no branch of modern 
gardening upon which so much depends as 
the preparing for a continued supply of 
flowers for the conservatory ; great prudence 
and forethought are required to prevent the 
gardener, from being left in the lurch at some 
particular seasons. It is not enough to pro- 
duce flowers, but they must be neatly grown, 
on handsome plants, and there must be a suc- 
cession. All the other horticultural buildings 
must be put in requisition for the feeding of 
the conservatory. The advice, therefore, on 
this subject is acceptable and important ; not 
only for building, but also for the heating, the 
management of the plants previous to and 
immediately after they have been placed in 
the house. There is then some notice of a 
protecting tent, as it is called. It means, 
however, nothing more nor less than a canvass 
house to place the plants under in winter, 
while we think it more important in summer 
time, where the plants can be shaded or ex- 
posed as the weather seems to dictate. And 
though the structure is given, we prefer the 
plan of a first-rate Tulip-house, because one 
side or other can be opened, the top can be 
rolled up or let down, and there is a much 
more complete command than can be got by 
means of the side apparatus, which are nothing 
more than canvass blinds, which pull up or let 
down at pleasure. Reference is made to the 
Horticultural Society's verandah, or front 
covering along their wall ; but that is only 
for winter-time, to lessen the power of frost. 
The cold pit is a much more rational protection 
for the winter-time, and perhaps for Erica is 
the best that can be constructed or used. We 
now glance at the dry and moist stove for 
tropical plants, in which the management is 
well laid down for the general collections. 
And we shall close our quotations with notes 
on a few particular and highly favoured 
subjects : — 
" G-loriosa superba. — This splendid plant, 
as the name fully indicates, is of great beauty 
and singularity. It is, nevertheless, but rarely 
met with in collections, and much more rarely 
is it seen in flower, although few plants are 
more easily cultivated and flowered. The 
following directions, by the late J. Sweet, of 
the Bristol nurseries, have been followed by 
us for several years, and with complete suc- 
cess : — ' Its failure,' he justly observes, ' arises 
chiefly from the defective method in which 
the roots are preserved during their inaction, 
and from the want of proper treatment when 
they first vegetate in the spring. Injured at 
these periods, the plants generally continue 
through the summer w r eak and unpromising, 
throwing up only a few small stems, which do 
not flower in sufficient strength or beauty.' 
The following is the essence of his judicious 
practice. In autumn, when the stems have 
died down, and left the root, which is a 
considerable-sized tuber, perfectly ripe, it is 
removed in the pot, and placed upon the top
