nse with. No furnace can supply the place of it; for,
though the furnace is an indispensable auxiliary in severe cold, and
though, well managed, it need not vitiate the air, yet, like all
contrivances for supplying heated air instead of heat, it has the
insurmountable defect of not warming the body directly, nor until all
the surrounding air be warmed first, and thus stops the natural reaction
and the brace and stimulus derived from it. Used exclusively, it amounts
to voluntarily incurring the disadvantage of a tropical climate.
Let the walls of the second story be upright. The recent fashion of a
mansard or "French roof" is only making part of the wall of the house
look like roof, at equal expense, at the sacrifice of space inside, and
above all, of tightness. For, though shingles and even slates will
generally keep out the rain, the innumerable cracks between the sides of
them can never be made air-tight, and therefore admit heat and cold much
more freely than any proper wall-covering. A covering of metal would be
too good a conductor of external temperature,--while clapboarding would
endanger the resemblance to a roof, which is the only gain proposed.
As to the size of the house, it is important to observe that its cost
does not depend so much upon the size of the rooms (within reasonable
limits) as upon the number of them, the complication of plan, and the
number of doors and windows. For every door or window you can omit you
may add three or four feet to your house. The height of the stories will
be governed by the area of the largest rooms;--what will please each
person depends very much upon what he is used to. In the old New-England
houses the stories were very low, often less than eight feet in the best
rooms. In favor of low rooms it is to be remembered that they are more
easily lighted and warmed, and involve less climbing of stairs. Rooms
are often made lofty under the impression that better ventilation is
thereby secured; but there is a confusion here. A high room is less
intolerable without ventilation, the vitiated air being more diluted;
but a low room is usually more easily ventilated, because the windows
are nearer the ceiling.
Mr. Garbett advises that the windows be many and small. This costs more;
and if it be understood to involve placing the windows on different
sides, the effect, I think, will be generally less agreeable than where
the room is lighted wholly from one side. A capital exception,
