SELECT ROSES, AND THEIR MANAGEMENT.

put in some of the prepared soil, introduce the 
roots of the plant, which should be easily dis- 
posed in a spiral manner, and work in the soil 
among them, using some lumps of charcoal, or 
broken oyster shells, or some such materials, 
among the soil to keep it open. It is impor- 
tant to lay the roots out easy and clear of one- 
another, by working the soil carefully between 
them, after which it must be shaken down 
firmly, by tapping the bottom edges of the pot 
on the potting-board. Set the pots in the bed 
at once, giving them some water to settle the 
soil firmly down. During winter, very heavy 
rains should be kept off them. All the varie- 
ties of China, tea-scented, noisette, and Isle 
de Bourbon roses, should be placed under 
glass about the end of November ; but they 
must have plenty of air day and night, except 
during frosty weather. The moss on the top 
of the bed where the hardy kinds are plunged, 
wili be sufficient protection for them, unless 
the temperature gets very low, when a mat 
may be thrown over the iron rods provided 
for the purpose of supporting them ; here 
they may remain till they are wanted for 
forcing. About a fortnight before they are 
set in the forcing-house, they should be cut 
over, the top of the soil broken up, and if need 
be, some of the old soil taken away and fresh 
added ; they should then be set in a cold pit 
or greenhouse. 
Forcing-house. — The best form of roof for 
a forcing-house, is the span roof; and the 
house should be provided with a hot-water 
tank down the centre under a plunging bed, 
with a walk round it, a platform at the sides 
and ends of the house two or three feet wide, 
and a door in the centre at each end. As the 
roof of such a house w 7 ould" not require more 
than one light in length on each side, every 
light ought to be made moveable, and the side 
lights also, so that every facility may be se- 
cured for giving plenty of air when the weather 
permits. One of the best kinds of tank is 
that constructed of galvanised iron ; the cover- 
ing is better if made of cast iron in the form 
of a net ; over this should be placed a layer 
of stones, just large enough to prevent their 
falling through the openings in the cover ; on 
these another layer of smaller ones, and above 
the latter, the plunging materials. In this 
way a fine moist heat is constantly kept up, 
without the necessity of pouring water between 
the pots. The flow in the tank should be 
from the end nearest the boiler to the other 
end, and the water should return in pipes 
under the side platforms. 
Temperature. — At whatever season roses 
are grown in-doors, they should be kept in as 
low a temperature as possible, so that the 
plants are kept growing ; 45 degrees at night, 
and 55 degrees by day is high enough, unless 
it be during sunshine. Advantage may be 
taken of every moderately still day to give air; 
but keep up the temperature. As nearly all the 
insects which infest roses in the open air 
attack them when grown in-doors, they must 
be very closely watched, and destroyed as 
soon as they make their appearance. 
Training. — As the shoots advance in 
growth, set them out in the form it is desired 
the plant should have when in flower. The 
most pleasing shape is the form of the well- 
grown bush in the open garden, but when in 
flower no sticks ought to be visible. 
Watering. — While the plants are growing, 
wdiether in-doors or out, water freely with 
clear manure water ; a little dusting of guano 
should also be laid on the surface of the soil, 
so that the water may carry its fertilizing 
properties with it into the soil. 
After the plants have done blooming, take 
off some of the old soil, and add fresh with 
some guano in it. When the spring frosts 
are over, they may be set in the bed in the 
open air. Examine them through the summer, 
to see they do not get dry at bottom. About 
the middle of October, re-pot them for the 
next season, and manage them as before ; the 
second year they ought to be stronger than 
before. 
FINE ROSES FOR POT CULTURE. 
For early forcing, the Common and Prolific 
Moss, Crimson Perpetual, Common Cabbage 
Provence, and Crested Provence, are the best. 
For a later bloom, select the Hybrid Per- 
petuals with double flowers ; even those that 
do not perfect their flow r ers in the open air, 
force exceedingly well. To ensure well 
coloured flowers of the Hybrid Perpetuals, 
they must have plenty of sun and air.

varieties to flower in April, May, and June ; 
for exhibition, or to adorn the conservatory or 
greenhouse: Moss. — Celina,Princesse Eoyale,
