1907. Excerpt: ... In smoky towns the same rules apply. It is
better to breathe fog-laden air from without than foul and
re-breathed air from within the room. A simple plan to keep out
soot, damp, etc., is to nail a piece of open cloth material over
the opening made by pulling down the window say two or three inches
from the top. This will allow of air entering, but will keep back
soot and dirt. The need for good ventilation at night is even more
urgent than during the day. LIGHTING THE HOME. The following
figures show how the various lights in general use vitiate the air
of a room: --During one hour an adult uses 3,000 cubic feet of air,
a gas jet uses 10,000 cubic feet, a good oil lamp uses 3,000 cubic
feet, a candle uses 1,500 cubic feet. Electric light does not in
any way affect the air either by fouling or by heating it. A gas
jet, while it is cheap and gives an excellent light, uses up at
least as much oxygen as three men. Gas, oil lamps, and candles,
besides using up necessary oxygen, also foul the air by giving up
to it carbonic acid gas, moisture, soot, and many other impurities.
Extra care should therefore be exercised with reference to keeping
up good ventilation when any of these lights are in use. And yet,
in spite of this, as Mrs. Clare Goslett says, "lighting-up time in
most homes means shutting-up time. At the very time of the day when
indoor air is most liable to contamination we close our windows and
doors, and make our rooms as air-tight as possible." Gas as a means
of lighting the home is good and cheap. It is also useful for
cooking and other purposes. Whenever it is so used, flues or other
means of carrying off the fumes should be provided. A gas jet
should never be used to warm a room, neither should it be left
burning all night. In the sickroom a nigh...
