THE COTTAGE GARDENER AND COUNTRY GENTLEMAN, September 25, 1860. 
We will give you one more genus to show tlie difference. 
Odontoglossum.—Perigone spreading, with narrow, acuminate, 
free segments, the outer and inner equal. Labellum clawed, 
continuous with the column at the base, not spurred, undivided; 
the lamina spreading, crested at the base. Column erect, mem- 
branously margined, winged on both sides at the apex. Anthers 
two-celled ; pollen masses two, solid; caudicles linear; gland 
hooked. Plant epiphytal, pseudo-bulbiferous; leaves plaited ; 
scape terminal, sheathed ; dowers showy. Every Odontoglossum 
has these generic characters. 
You will observe by the above characters that in order to 
know any Orchid you must procure a good botanical work that 
describes each genus. In the meantime, however, you may con¬ 
sult any of your neighbours who cultivate Orchids, and they 
would tell you which of your plants are Oncidiums, which 
Maxillarias, which Dendrobimns, &e. Mr. Ellis, gardener at 
Norwood Hall, near Sheffield, is near you, and is a good man to 
refer to ; or Mr. Payne, gardener to E. Smith, Esq., near Nor¬ 
wood Hall, is equally knowing in Orchid lore. Either of them 
would gladly give you information on the subject.] 
ON HEATING A VINERY, PEACH-HOUSE, 
AND HOT-PIT. 
I am at present erecting a small Vine and Peach-house, 32 feet 
long and 9 feet wide inside; back wall 13 feet high, allotting 
12 feet for the Vines, and 20 feet for the Peaches, divided by a 
glass partition. I propose heating it by six-inch fire-clay pipes 
(from a furnace), extending the whole length of the house, 
returning through the Peach-house to the glass partition, and up 
the back wall. The vinery will be next the furnace, in which 
there will be only one pipe. I am also erecting cold and hot- 
pits : the latter I propose to heat by a water-tight tank under it, 
with pipes from a furnace through the water, the tank to be 
■covered with slates, on which the bed of the pit will be laid. I 
shall feel obliged by your opinion on this plan, with any sug¬ 
gestions you may think useful.— An Amateur. 
_ [We suppose there is a certain reason for bringing the return- 
pipe only as far as the partition; if not, we should prefer 
returning it all the way, and then the vinery and Peach-house 
would be more equal as respects temperature. Were the 
houses ours, we should prefer two pipes in the vinery con¬ 
nected with an elbow, and dampers or plugs on both pipes beyond. 
By this means and a damper at the elbow we could heat the 
vinery without heating the Peach-house, and could start the one 
before the other, if we deemed it advisable. We should also prefer 
nine-inch pipes to six-inch, and we should like the flow-flue to 
be formed for four feet or so from the furnace of bricks. Other¬ 
wise there is nothing objectionable in the plan proposed. At each 
corner we would have the pipes terminate in a small hollow 
column of brick, covered with a tile, so that all sweeping and 
cleaning of pipes might be done without disturbing them. Our 
chief reason for recommending nine or even twelve-inch pipes, is 
owing to the fact, that if the fuel is smoky, the six-inch pipes 
would be encrusted soon with soot; and if a strong heat was 
used to burn it, the effluvia given off would not be healthy. 
On the principle that what a man himself fancies and plans he 
will generally do well, we have no objection to find with heating 
your hot-pits in the way proposed, provided you can make your 
clay pipes watertight, and have a flue of brick for a few feet from 
the furnace. We do not know what your object is with heating 
a tank of water with such pipes passing through it, and covering 
the tank with slate on which the bed of the pit will be laid. If 
these slates are close jointed so as not to admit of steam passing 
through, the heat from such a combination will be as dry as from 
smoke pipes alone. Some people speak of the moist heat from 
hot-water pipes, hut if these pipes or tanks are so close that no 
vapour or steam can escape, the heat from a pipe is just as dry as 
from a flue. In the latter case some deleterious gases may ac¬ 
company the heat; but, as to dryness, heat for heat, there can be 
little or no difference. Did we consult economy, therefore with 
your hot-pits, we would do without the tank and without the 
slate covering, would surround the flue or clay piping with open 
rubble covered with gravel, and on that place the bed, with holes 
left by which water could be poured on the rubble when a moist 
heat was required. The moist bottom heat being given by 
stopping the openings, and the moist top heat by opening them. 
Atmospheric heat could be obtained by opening and shutting 
elides at pleasure opposite the rubble. However, have the tank, if 
such is your pleasure. We merely give the hints as to economy. 
7 0 w ] uld P ref er iron pipes for a boiler for such a purpose, as 
they seldom leak; but the smallest hole or leakage at the joints 
m your plan will let the water from the tank in, if you still have 
a tank, and that will soon put your fire out. With regard to 
works which will be useful to you, read our 11 Manuals for the 
Many. J 
ROKEBY. 
Rokeby, the delightful residence of G. Morrit, Esq., is situated 
on the banks of the Greta, in North Yorkshire. 
The circumstance of the “Great Magician’’having taken the 
scene of one of his poems from this place has given it a notoriety 
it might not have possessed; at the same time few places can 
vie, with it in natural beauties. The mansion is a plain squaro 
building situated in a beautiful park. On the west of the house 
are a number of Roman votive altars arranged on a square plat¬ 
form on the grass, of great interest to antiquarians. A little 
beyond, well screened by trees, are the stables, offices, and kitchen 
garden. The garden is small, well cultivated, and neat; it con¬ 
tains a range of vineries, greenhouses, and Peach-houses. In 
the latter is a very fine Stanwick Nectarine, which, under the 
able management of Mr. Einlay, produces exceedingly fine fruit 
without cracking. The greenhouses contain a good collection of 
plants well managed. There is also a large detached vinery, 
which produces first-rate Grapes. 
On the east side of the mansion is a flower garden, a walk 
from which conducts us to the banks of the Greta. This is 
decidedly the most beautiful part of the grounds. 
“ A stern and lone, yet lovely road, 
As e’er the foot of minstrel trod !” 
The river Greta runs with great rapidity over a bed of solid 
rock. The valley at times is so narrow that the walk has been 
made with great difficulty—now opening into beautiful glades, 
now confined in narrow gills, while lofty cliffs of limestone-rock 
overhung with Ivy, the crevices filled with Ferns and shrubs 
passing through a fine grove of aged Yews ; high above which, on 
the opposite side, perpendicular white cliffs lift their heads, 
above which the old tower of Mortham with its elegant battle¬ 
ments is seen. Before the gate yet stands 
“ A massive monument, 
Carved o’er in ancient Gothic wise, 
With many a scutcheon and device.” 
The situation of which before the old entrance-gate is singularly 
beautiful. 
It is much to be lamented that the old tower is much dis¬ 
figured by modern buildings added thereto. The old hall where 
the fight took place, so graphically described by Sir W. Scott, is 
now converted into a cart-shed. 
Few localities are so rich in native plants as the banks of the 
Greta and Tees. Campanula latifoJia attains a height of five 
feet ; and Trollius europseus a size seldom seen in cultivation. 
Woodsia ilvensis, once found on the banks of the Tees, is now 
eradicated; but a future paper on the Tees and its plants shall 
follow if worth sending.—R. C. 
CULTURE OF VINES IN POTS. 
“ £ A. Z.’ will be much obliged by the publication of some of 
the leading points in the culture of pot Vines, from planting the 
eyes to fruiting, with the heat required for sorts as under—viz., 
Muscat of Alexandria, Black and White Frontignan, St. Peter, 
Muscat Hamburgh, Black Hamburgh, Golden Hamburgh, 
Trentham Black, and Black Champion. ‘A. Z.’ cannot find 
directions in The Cottage Gardener, with the exception of 
answers to questions asked by “A Country Baker,” with 
regard to keeping Pines and Vines together. ‘ A. Z.’ would keep 
his Vmes in a house on stand (not pit), until fit for fruiting in an 
orchard-house. 
“ In Mr. Rivers’ directions in his book on pot Vines, he simply 
says, ‘ Get a Vine from eye, cut it down to so many eyes.’ Now, 
the query is, Would a Vine seven feet high break any of the 
bottom half of the eyes ? I think not. Therefore, why not have 
them shorter with fruit nearer the pot ? ” 
“A. Z.” must not have examined The Cottage Gardener 
very closely, or he would have found explicit and minute direc¬ 
tions as to the culture and management of Vines in pots. To save 
ourselves the trouble of looking over previous volumes, and also
