the apex, one side of which is higher than the other, and 
with a shallow suture, which is also higher on one side. 
Skin remarkably thin and tender, of a lemon-yellow colour, 
with crimson dots on the shaded side, but covered with a 
crimson cheek and darker dots of the same colour on the

QUERIES AND ANSWERS. 
HEATING A GREENHOI'SE FROM A KITCHEN FIRE 
PLACE—WOOD versus IRON FOR FRAMES. 
“ 1 am about to erect a span-roofed greenhouse nearly forty feet 
in length ; and, as one end thereof will be within a short distance 
of the kitchen fireplace, I think of obtaining an adequate supply 
of heat from that source. We shall have no difficulty in p’acing 
the pipes (four-inch) sufficiently high to ensure perfect circu¬ 
lation ; but how the supply of artificial heat is to be cut off when 
not required is at present not so apparent. My mechanician tells 
me the boiler would burst if the flow of water through the pipes 
were intercepted : and his notion is, that the occasional inter¬ 
position of a thick plate of iron, to fit in a groove, between the 
boiler (which will form the back of the fireplace) and the fire 
itself, will suffice to prevent the water being more than slightly 
heated. I doubt the fact, however; and, at any rate, am of 
opinion that the application and removal of this plate would be 
attended with trouble and inconvenience. 
“The roof will be glazed with stout glass adapted for the 
purpose. It was my intention to use iron rafters, ten inches 
apart; but in Vol. XII. you give so decided a preference to wood 
over iron as to shake my determination in this particular. I do 
not attach much importance to the objection on the score of 
frequent painting ; and am told there will be no risk of breakage 
from the sudden contraction of the metallic bars in frosty weather 
if we make use of the strong glass I have named, and interpose 
strips of India rubber in the glazing. What think you?”— 
G. Chapman. 
[We thoroughly agree with what y< u have stated as to the 
usefulness of slips of India rubber in such cases of glazing, if 
deemed necessary ; and also that a plate of metal, enclosing a 
space of air between the metal and the boiler, would tend very 
much to keep the boiler from getting very hot when heat was 
not wanted in the greenhouse. But supposing that you had a 
cook or kitchen-maid that took such an interest in the gardener, 
or in the greenhouse, or studied her own comfort a3 to heat so 
much as to block off so far the fire from the boiler in the hot 
summer months, what are you to say to the housemaid, the 
scullery-maid, and now and then the groom, when they respec¬ 
tively want a good supply of hot scalding water, and have no 
other resource to go to but the kitchen boiler? If the want of 
plenty of hot water in the summer become an excuse for the want 
of scrubbing, and scouring, and fomentations, and washes for a 
favourite horse, you may begin to think it was not all gain when 
you heated your greenhouse from a kitchen boiler, and resorted 
to such a mode for shutting off the heat from the greenhouse. 
Besides, supposing all these difficulties got over, you must manage 
the fire yourself as to the blocking, or have a major domo with 
the right to wield the kitchen poker, and also have the entree of 
the greenhouse; or you must be superior to a growing custom 
among ladies and gentlemen of looking out for fresh servants, 
when they discover, that even upon such interesting matters, the 
young gardener and the blooming artiste of the kitchen have 
frequent friendly consultations: otherwise, or for particular 
reasons, it is desirable to keep the manager of the greenhouse and 
the manager of the kitchen from getting together, either about 
hot water or cold water. Then, as we shall see, however useful 
the iron block may be, and for varied uses, it would be desirable 
to shut off the heat as respects the greenhouse, when deemed 
necessary, without either going to the kitchen, or endangering a 
blow-up from the flight or bursting of the boiler. 
The want of particularity as to the supplying the boiler with 
water may make this gossip more generally interesting by leading 
us to notice the two modes by which such boilers are generally 
managed ; as, if not generally useful, answers must be shorter 
than they otherwise need be. A great many amateurs would like 
to heat from a kitchen boiler, and are deterred by what they are 
tola are great difficulties ; while, if managed by themselves, there 
can be little difficulty, if the circumstances are suitable. 
The most common of these useful boilers are furnished with a 
tap for drawing off the water, and a moveable lid for replenishing 
with water, either as it is drawn off, or thrown off by evaporation, 
as from the lid of a tea-kettle. If it is attempted to heat a green¬ 
house from such a boiler, it can only be done when the pipes go 
at once and all through the house nearly on a level, and there is 
no part of the water in the pipes higher than within two or three 
inches of the top of the boiler. If any part of the pipes is 
lower than where the return-pipe enters the boiler, the circulation 
will be apt to be languid and defective. Under the above cir¬ 
cumstances, whenever the water is heated, circulation in the pipes 
will commence. When not wanted, the flow should be shut off 
by a valve or tap. The cheapest way would be to have a short 
iron pipe—say, one inch and a half in diameter, connecting the 
boiler with the round pipes in the house, and the tap placed out¬ 
side or inside the kitchen, according as an in-door, or out-door, 
servant had the management of the greenhouse heating. When 
the tap or taps are turned off, for the flow-pipe is the chief thing, 
there would be no heating of the house; and instead of any burst¬ 
ing of the boiler, there would, if there were no blocking off from a 
strong fire, be a considerable amount of steam constantly escaping 
by the lid opening up the chimney. If the boiler is small, this 
will be attended with no evil. If large, and the fires hot, it will 
sometimes be an annoyance, to which we will presently allude. 
Accidents sometimes occur with such boilers from the simple 
fact of forgetting to fill them as they are more or less emptied. 
To guard against this, when circumstances will permit it is 
preferable to have a close-headed boiler—that is, one without a 
moveable lid, but fed from a cistern by means of a pipe, that 
cistern raised some feet above the top of the boiler, and kept con¬ 
stantly supplied with water by means of a floating ball-cock, which 
lets in water into the boiler just as fast as by any means it is 
drawn, or thrown by vapour out of it. The advantage of this 
mode, so far as heating other places is concerned, is, that your 
heating-pipes can be placed at any height, provided they are as 
high as the boiler at the lowest, and not higher than the water 
in the supply-cistern at the highest. An air-pipe at the highest 
point of the pipes in the greenhouse would dispense with the 
necessity of having any other opening. The boiler and pipes 
would all be supplied from the ball-cock cistern. Taps or plugs 
should be used for shutting off the hot water when necessary. A 
simpler mode might be this. Bring the flow and return into a 
stand, or a cistern inside the house. It matters little about the 
size of these connecting pipes. We should be satisfied with one 
inch or one inch and a half bore, and use three or four-inch ones in 
the house. Well, all you want when you desire no heat, is to 
insert a wooden plug in the end of these pipes and keep it there. 
All right as to shutting off heat, but then the boiler would 
burst if there were the usual quantity of heat. So it would be 
likely to do if there were no outlet. In the present case, if the heat
