_U, is an urn with a spigot, and a pipe on the opposite side le: 
with a gradual descent obliquely into the fire through an — 
the plate of the stove. 
B, is a similar aperture to receive _ pipe from a boiler in the 
same manner as at that attached to the u 
-P, is the gas pipe six or eight sdilgeas in diameter, of Praes the 
various directions within the canvass are indicated by dotted lines. 
I, is a piece of sheet iron, six inches broad, extending across the 
_top and down the sides of the stove in front serving for an attachment 
to the cloth, and sufficiently insulating it from the hot metal. The 
front of the stove thus constitutes a part of the circular enclosure. 
F, is a pipe which may be opened or closed at pleasure for con- 
veying to the chimney any fumes which may chance to escape into 
the kitchen. 
_ 'T, is a wooden trunk, beneath the. floor, for conveying pure air to 
the exterior of the furnace. 
M, its aperture within the air chamber. 
h, h, are light iron hoops within the canvass covering to — it ex-

widhiioae of the ical so that the eye of a ees seldom de- 
tects the source of heat unless he happen to pass over the aperture. 
The canvass is rendered incombustible by any heat which can be 
radiated from the stove, first, by dipping it in a strong solution of 
alum, and afterwards by covering both surfaces with a coat of white- 
wash, composed of eight parts of quick lime to one of common salt. 
he same covering has been three years in use without the slightest 
~ sign of combustion. The whole apparatus may have cost, in ad- 
dition to the price of the cooking stove, about five dollars. It canbe 
put up or taken down in an hour, and.at the approach of warm weath- 
er, when heat is no longer wanted for the other apartments, the aper- 
ture in the floor is closed, the canvass detached, the grate and base 
- of the stove removed to an ordinary kitchen fire-place; and with 
proper supports for boilers and other apparatus, a summer cooking 
Tange is at once constructed out of the materials which had been 
used in the winter, and thus no change of fuel becomes necessary at 
that season. With.a gas pipe of sufficient dimensions to convey 
away the fumes, little annoyance can arise from that quarter. To
