nothing can l)e more delicious. "We can confidently 
and most earnestly recommend tMs plant as quite a 
gem in its way, and sm-e to give satisfaction. Pay 
timely attention to climbers of all kinds ; if not abeady 
done, let them he pruned and regulated without more 
delay. Maintain a temperatm-e of 45 degrees by night, 
rising ten or fifteen degrees in the day-time. Syi'inge 
twice or thrice a-week on bright clear mornings, and 
keep a healthy growing atmosphere by sprinlding every 
vacant part of the house morning and evening- 
Camellias which have bloomed heavily, will he bene- 
fited by a copious watering of weak manure water, and 
Acacias will be grateful for a similar favour. At 
page 84 some remarks ^dll be found upon the manage- 
ment of Pyramidal Pelargoniums, illusti-atcd very 
tastefully by designs from the pencil of H. N. Hum- 
phi'eys, Esq. "We would paiticulai'ly direct atten- 
tion to RoUison's Unique, as a kind admirably 
adapted for this style of management. The following 
kinds have also been recommended as likely to answer 
the same pm-pose — Forget- me-Not, Magog, Ai'mada 
Superb, Miss Holford, Gigantea, Priory Queen, Orion, 
IvigTess, Milo, Centurion, Gulielma, and Eosamond ; 
and as forcing kinds. Admiral Kapler and Sm'pass

Orangery. — Although the plants belonging to the 
genus Citrus are much admii-ed in this country for the 
delicate scent of their flowers, and the noble appearance 
of the plants, it is a matter of regret that they are not 
more cultivated for their fruit, which, under proper 
management, may be grown to great perfection, as to 
flavour, and in size quite as large as those imported 
from more favoiu'ed regions. Thirty years ago, at the 
writer's native place, two houses were devoted to the 
cultivation of the Citrus family, from which the pro- 
prietor was as regulai-ly supplied with fruit, both for 
dessert and confectionary pm-poses, as vrith grapes or 
pines from the other houses. The back waU of each 
house was planted with Lemons, Limes, Citi-ons, and 
Shaddocks, trained as systematically and unifoi-mly as 
the most fastidious could desire, clothing the wall with 
noble foliage, and presentiag at all seasons, but more 
especially in the autumn, specimens of first-class culti- 
vation, which the best gardeners of the present day would 
be proud of. The centre of the house was filled with 
standard trees, laden with hundi'eds of golden fruit; 
and along the front border, trees were trained horizon- 
tally upon a low trellis, so that the house was clothed 
from side to side. All these plants were planted out in 
rich hor lei's warmed, to some extent, byflues traversing 
their sides ; and every care was taken of them through- 
out the year. The plants were not turned out in the 
summer season, to be alternately scorched and starved 
upon a terrace ; neither were they buried in a sort of 
mausoleum through the winter; but every care was 
taken of them at all seasons ; and most nobly did they 
repay the kindness. It is now many years since the auc- 
tioneers' hammer consigned the "favomites of our child- 
hood's happy years" to the hands of the ruthless spoiler ; 
but still, we cannot forget our English Orange-groves, 
where the fruit was none the worse for being stolen ; 
and we recur to them here, with the hope that some of 
our noble patrons of horticulture will step in and rescue 
them from that oblivion to which, in this coimtry, out- 
door summer cultivation is fast hurrying them. Dming 
the year we shall have many chances of recuiTing to 
their cultivation ; in the meantime, see that the plants 
are quite healthy and clean. Remove the sm-face soil 
down to the roots, and replace it with very rich com- 
post, consisting of tm-fy loam, rotten dung, and leaf 
mould, to which a little thoroughly decomposed pigeons' 
dung may be added. Ee-pot or re-tiib any plants 
that require it ; and give each a good soaking of water. 
Floiocr Forcing House. — Continue to introduce 
fresh supplies of bulbs of various kinds, and American 
plants, with Lilacs, Roses, &c., and remove those show- 
ing colour to the, Conservatory. Forsythia viridissima 
■n-ill be found an excellent forcing plant, as will also 
"Weigela rosea, and Mi-. Haitweg's Cajifomian species of 
Ceanothus. Provide a succession of Indian Azaleas ; 
some of the flner kinds may now be started, by intro- 
ducing a fewplants every week. Pelargoniums in this 
house will soon be in bloom. Give them plenty of air 
daUy, and some manure water. Keep the temperature 
to 60 degrees by night, increasing from 10 to 20 degi-oes 
with sun heat. Syringe daily to generate a moist 
atmosphere, and guard against insects. 
Reserve Fits. — As fast as the plants are introduced 
to the forcing-house, fill their places with Roses and 
other things to keep up a regular succession. Procure 
and pot Roses for next year's forcing, as dii-ected in the 
Rose Garden, and pot also Sweet Briers, Honeysuckles, 
LQacs, &c., for the same purpose. A good succession 
of Pinks and Carnations may also be forwarded in this 
pit, and the finer vaiieties of Sweet "WiUiam will also 
be found excellent for forcing. Pot Tuberoses for the 
autumn. 
Routine. — Towai'ds the end of the month it may be 
necessai-y to shade the plants a little, and for that 
pm-pose it will be advisable to get the blinds fixed pre- 
paratory to their being wanted. It will not, however, 
he necessary to shade unless the day is very bright. 
A, 
Orchid Souse. — Let there be an uniform tempera- 
tu'e kept up in this house, and no unnecessaiy excite- 
ment fi-om over-heating must be permitted. TSTien the 
sun shines out cleai", give a little air, but avoid draughts. 
Keep all growing plants properly moist at the roots, but 
avoid at present indiscriminate wateiing. Keep the 
atmosphere moist by frequent sprinkling, as before 
dfrected ; let nothing be neglected, but treat eveiy plant 
as if intended for a specimen. Look well at every 
specimen previous to its opening its blooms, and see 
whether it could be improved by the aid of a little 
arrangement of the shoots or pseudo-bulbs. This, to- 
gether with the use of nice green moss, placed upon the 
sm-face of the pot, very materially enhances the beauty 
of most Orchids. As regards shifting these plants, I 
would here observe, although they do not want repotting 
eveiy year, I scarcely remember seeing a plant that had 
been properly shifted but showed instant signs of im- 
proved health and vigour. Upon this evidence, I say 
shift them as often as they seem to require it, should 
that even be annually. This applies equally to plants 
on blocks and in baskets. The proper time to do this 
is just as they are commencing their new gi-owth. 
Great care must be taken not to injure their roots, and 
they must be made firm upon the soil, moss, or blocks. 
It is most essential that the blocks, moss, baskets, and 
soil, be at the same temperatm-e as the house in which 
the plants axe growing, in order that they receive as 
little check as possible. 
Store. — Now that the weather begins to assist, the 
temperatm-e of this house may be increased to sixty 
degrees minimum and seventy degrees maximum by 
fire-heat, increasing ten or fifteen degrees on clear, 
bright days, by sun-heat. Ventilate freely at every 
favourable opportunity ; but, as before dfrected, guard 
against draughts, especially near recently potted speci- 
mens. In watei-ing, be guided by the weather, but avoid 
both drought and satirration. As the plants increase in 
growth, water may — indeed must — be increased also ; 
but, as the temperance advocates say, observe the happy 
medium enough, but avoid saturation. Plants, how- 
ever, when in free gi-owth, that is, when hard at work, 
do not object to sb-ong drink, and therefore a tub of 
liquid manure must always be ready for use. Let 
moderation be your rule, and avoid using it by all means, 
except in a very -weak state. Maintain a moist grow- 
?
