fire on the
hearth-plate, not to be incommoded by the smoke, the sooner and
more will the room be warmed. At night, when you go to bed, cover
the coals or brands with ashes as usual; then take away the dogs,
and slide down the shutter close to the bottom-plate, sweeping a
little ashes against it, that no air may pass under it; then turn
the register, so as very near to stop the flue behind. If no smoke
then comes out at crevices into the room, it is right: if any smoke
is perceived to come out, move the register, so as to give a little
draught, and it will go the right way. Thus the room will be kept
warm all night; for the chimney being almost entirely stopt, very
little cold air, if any, will enter the room at any crevice. When you
come to re-kindle the fire in the morning, turn open the register
before you lift up the slider, otherwise, if there be any smoke in
the fireplace, it will come out into the room. By the same use of the
shutter and register, a blazing fire may be presently stifled, as
well as secured, when you have occasion to leave it for any time; and
at your return you will find the brands warm, and ready for a speedy
rekindling. The shutter alone will not stifle a fire, for it cannot
well be made to fit so exactly but that air will enter, and that
in a violent stream, so as to blow up and keep alive the flames,
and consume the wood, if the draught be not checked by turning the
register to shut the flue behind. The register has also two other
uses. If you observe the draught of air into your fire-place to be
stronger than is necessary (as in extreme cold weather it often is)
so that the wood is consumed faster than usual; in that case, a
quarter, half, or two-thirds turn of the register, will check the
violence of the draught, and let your fire burn with the moderation
you desire: and at the same time both the fire-place and the room
will be the warmer, because less cold air will enter and pass
through them. And if the chimney should happen to take fire (which
indeed there is very little danger of, if the preceding direction be
observed in making fires, and it be well swept once a year; for, much
less wood being burnt, less soot is proportionably made; and the fuel
being soon blown into flame by the shutter,
