THE COTTAGE GARDENER.

HEATING A SMALL ITT Oil HUME. 
The above is a sectional drawing of an apparatus I 
have invented for warming a large two-light frame, as a 
forwarding pit to a small conservatory. And as I am sure 
that my success warrants my recommending it to other 
amateurs who have the same dislike to manure-beds as my¬ 
self, I send you an explanation for working the same, and I 
am satisfied that no mode can beat it for economy, both in 
first cost, and in keeping up a cheap and regular heat. 
In the first place, the stove is a mere cylinder of sheet iron 
rivetted. It is four feet long, and has a ring inside at 1, for 
the fire-bars to rest on. 
2 is a small sliding-door to admit air under the grate-bars, 
or to draw up higher than the bars if required. 
•1 is the cylinder itself, four feet long by eight inches wide, 
inside. 
I is the first cover with a draught hole in it, to be regulated 
by a sliding shutter or regulator 
The cylinder has a ring round it outside, four inches from 
the top, with a tapering edge that the conical top, 5, may fit 
close on. 
f> has a two-inch pipe to conduct the gas out of the pit. 
This stove is fed with charcoal, by removing the lid, 4, and j 
filling the cylinder, 3; and I may here say that this stove will i 
bum 20 hours, but 1 work mine for 24 hours. It will sutti ! 
ciently heat the air of any large two-light frame, and serves . 
for heating the bed, or rather the under part of it. 
0 is a one-inch copper pipe, conducted through the cylinder’s I 
side, bending, and placed four inches above the grate-bars 
at 1. 
This copper pipe is joined to lead pipes about six inches 
from the cylinder's sides, the lower one, 7, coming from the 
tank, 8—a box eighteen inches by ten, by eight deep, covered 
with a slate. The other pipe,!), makes the circuit of the bed, 
or, rather, is traversed backwards and forwards, and finally is 
led into the tank at 10. 
Here, then, is an apparatus complete; and now for the 
main secret to be carefully observed by any one wishing to 
erect one. The pipe from 0 to 10 must on no account be 
below the level of the pipe, 7, (i ; this is the grand secret, all 
the rest is plain. 
Set the cylinder stove in one comer of the bed, or frame 
and bed; the tank 8, on bricks, as well as the pipes, 7, 8, i); 
make a hole in the slate over the tank, 8, and set a draining- 
pipe upright, 11, so that, the top of this pipe will he above the 
soil of the bed. This will give moisture and a gentle steam, 
which, if not desired, can be stopped with a slate or sod- 
cover. The drain pipe, also, is the place to feed the tank with 
fresh water. I filled up my pit with broken bricks, about six 
inches above the pipes, and then laid sods and bark on them, 
and thus obtain a nice bottom-lieat. 
I have placed my two-light frame on brick-work, two feet 
high, 12, and placed a small door at the part nearest the 
stove door, as shewn by the dotted lines at 12, for the purpose 
of admitting the draught to the fire, and removing the ashes 
i when wanted. The fire-bars must not be more than three- 
eighths of an inch apart, or the fuel will be greatly wasted by 
i dropping through before it is consumed. I have no doubt 
but that a patent for this machine would pay me, but I have 
not the time nor inclination to take one out, but wish to 
diffuse the knowledge of it through your valuable pages, and 
i shall be glad to give any further explanation through the 
same medium. W. X. W. 
THE PHYSIC GARDEN. 
By a Physician. 
Mai.vaceje.— 1 “ The uniform character of this order,” says 
Dr. Lindley, “is to abound in mucilage, and to be totally 
destitute of all unwholesome qualities.” It is not, therefore, 
a matter of wonder that their virtues were so extravagantly 
extolled by the rude practitioners of former days : they found < 
them harmless, consequently, they tried them for every 
malady, and wherever recovery followed the plant adminis¬ 
tered had all the credit of it. 
Under the heads of the two species which I propose to 
describe, I shall mention the properties which really belong 
to them ; but before doing so, I must just refer to two other 
plants of interest in this order—one is the Hollyhock 
(Allluea rosea), from which all those beautiful varieties of ; 
this noble and majestic plant have been derived—ornament¬ 
ing, as they do, our garden walls with their gay and stately 
aspect; the other is the (jossypium herbarium, from the • 
heads, or seed vessels, of which is obtained that most valu¬ 
able commodity, cotton. I may add, that that favourite 
garden flower, the Hibiscus, also belongs to this order. 
Mallow (Malva sylvestris. —Few persons could be found 
in the rural districts of England who do not know that com¬ 
mon plant, the mallow. Its handsome lilac flowers, and 
numerous leaves, render it a conspicuous and picturesque 
| object on almost every road-side; and its curiously-formed 
seeds are often played with and eaten by country children, i 
! and called by them “cheeses:”
