cient dwellings are perhaps contented, that they can by closing the 
fire-place with a board, and conveying through this the pipe of a 
small stove, escape the dreariness incident to their former mode of - 
consuming fuel. They do not appear to imagine that as the gas is 
red hot at the moment of entering the chimney, it would, if conduet- 
ed a considerable distance within the apartments, be capable of im- 
parting to the air of the room, several hundred degrees of its heat. 
The admixture of unburnt air is the evil of open grates and fire 
places; the escape of hot gas without discharging its people —_ 
is that of close stoves as now generally arranged. 
The culinary operations of almost every family involve an im- 
mense waste of heat, and of heat too which might be turned to 
valnalie account, ware ome a small portion of the ingenuity bestowed 
rned towards that much neglected branch 
of domestic operations. “Philosophy i is slow in descending to the

“Coquus preter jus fervens, nihil novi potest imitari.” 
fudeua,~ a new process or a new fashioned utensil is often ogee 
by that important dignitary, as a signal for open hostility, or fora sul- 
len retirement from the “ place” which it has invaded. Henee from 
ten to twenty cords of wood are annually consumed in many a family 
for the sole purpose of cooking, while every other part of the estad~ 
lishment is supplied with anthracite. In economizing culinary heat, 
it seems probable that at least one half of all the fuel usually TT 
ed in families may be saved. 
The method proposed to be substituted for that which has si 
described, is one which has, under some modifications, been employ~

more limited scale, for the warming of private buildings. It consists 
in placing in the basement story, or in the cellar, (as the case may 
be,) a single furnace capable of effecting the combustion of as much 
fuel as will be required to heat all parts: of the house. Where an- 
thracite: i is employed, this arrangement is perhaps more desirable 
than where any other fuel is used, because the labor of attendance 
is: se to. an amount utterly insignificant, compared with 
the expense of fuel and is extremely small compared with —_ 
would be with some other kinds of combustibles. Pad 
The furnace may be either of cast or rolled iron, the latter b ein j 
preferable on account of its lightness and pliability ; the former, “fr
