Williams, and a vast number of other useful spring- 
flowering plants, should be sown out of doors at once. 
Forward all choice and tender annuals, as they may be 
useful for filling some spot in the flower-garden. J. C. 
Rose Garden. — As the month of March has been so 
favourable for planting, nothing of that work ought to 
require to be done, except the half-hardy kinds which 
have been kept during winter in pots. All priming 
must be finished early in this month, and very recently 
planted plants should have a good watering, after which 
the ground should be well stirred, and left rough (or 
at least not raked) for the frost and sun to pulverize it. 
Beds to be planted at the end of this month or beginning 
of May, with Tea scented, ^Noisette, Isle de Bourbon, 
&c., should have the soil frequently tui-ned over to ex- 
pose it to the action of the sun and frost; in fact, too 
much pains cannot be taken with the soil now; the 
future bloom wiU aniply repay for any exti'a trouble. 
Watch carefully for insects, and see that no fresh-planted 
roses are being blown about for want of tying. 
Forcing House. — Continue to introduce fresh plants 
into the forcing house, as they are required. Take care 
to set them in such a part as they may get plenty of sim 
and ail- ; for, be it remembered, roses want to be brought 
on very slowly to get them worth looking at. In short, 
nothing is more injurious to roses than a high tempera- 
ture ; 45 degrees at night is quite high enough, and 50 to 
55 degrees by day, unless it is sunny. Look very closely 
for insects, and tie the shoots out as they require it.

Arboretum. — The preparation of the sites and mode 
of planting Coniferous plants having been fully de- 
scribed last mouth, the operation of planting may be 
safely proceeded with. The planter of ample means 
and space will be able (I had almost said, on him it de- 
volves as a duty for the public good) to plant every 
species as they are introduced, in order to prove how 
far they are capable of being acclimatized. Little doubt 
can be entertained as to the perfect hardiness of the 
North American species, but I fear that we may not 
yet speak so confidently of the Mexican ones. As there 
may be many persona who have not space enough to 
spare to form an extensive Ai-boretum, yet would \\k.e 
to embellish their lawns and pleasru-e grounds with a 
few of the best of these plants, I will append a short 
descriptive list of a few which, having been thoroughly 
proved, may be confidently recommended. 
Abie.'i Dquglasii (The Douglas Fii', from North 
America, introduced 1826). — This lofty-gTowing tree, 
which, in its habitat, attains to the height of 150 feet 
and upwards, promises to become one of the most mag- 
nificent oi-naments of the Ai-boretum. Its rapid growth 
and the graceful distribution of its splendid foliage, 
together with the great beauty of its inflorescence, com- 
bine to render it one of the most desirable trees of the 
genus. The leaves, when bruised, emit a most agree- 
able fragrance. It delights in a cool situation, rather 
moist than otherwise. 
Abies Morinda (The Weeping Spruce of the Hima- 
laya, 1818). — A most appropriate name for a beautiful 
tree ; the di-ooping habit is caused by the denseness of 
the foliage, the weight of which causes all the young, 
slender shoots to di-oop from the main stems very gxace- 
fully. The variety called Smithiana has been by some 
considered as distinct fi-om Morinda, an opinion with 
which I camiot agree, as we avoU know that many 
species of the tribe will present slight variations of 
foliage and habit; but to constitute them as distinct 
varieties can only cause confusion. 
Abies Menziesii (California, 1831). — As a contrast 
to the diooping habit of Morinda, the rigid aspiring 
habit of this species is very desirable; its growth is 
rapid, and the beautiful glaucous appearance of the 
foliage is very sti-ildng. 
Cedrus Sendara (The Himalayan Cedar, 1822). — 
This is now becoming as well kno^vn as it is higlJy 
appreciated, and needs no description. For a small 
place, I would ad-idse that the planter select seedling 
plants with a dense and compact foliage, as cutting 
plants are apt to grow more open and rigid, similar to 
the Cedar of Lebanon. 
Pitnis insignis (California, 1833). — No place, however 
small, should be without this most elegant and beautiful 
Conifer. The contrast between it and other species is 
eminently striking, and consists not only in its graceful 
habit, but also the peculiarly delicate colour of the 
foliage, particularly in the young shoots. It is a fast 
grower. 
Pimis ponderosa (North America, 1828). — If to the 
insignis be accorded the palm of graceful, delicate 
beauty, that of robust grandeur belongs to this, which 
is truly a magnificent species, and ai^peai's likely to 
become a valuable timber tree. A specimen before me, 
planted about 18 years, measures five feet six inches 
round the bole at two feet fi-om the ground. The wood 
is considered to be specifically heavier than that of any 
other Conifer, hence its name. As an ornamental tree 
it is second to none.
