Every girl should
be trained to be "a wise woman" that "buildeth her house" aright.
There is but one mode of ventilation yet tried, that will, at all
seasons of the year and all hours of the day and night, secure pure
air without dangerous draughts, and that is by an exhausting warm-air
flue. This is always secured by an open fireplace, so long as its
chimney is kept warm by any fire. And in many cases, a fireplace with
a flue of a certain dimension and height will secure good ventilation
except when the air without and within are at the same temperature.
When no exhausting warm-air flue can be used, the opening of doors and
windows is the only resort. Every sleeping-room _without a fireplace
that draws smoke well_ should have a window raised at the bottom
or sunk at the top at least an inch, with an inclined shelf outside
or in, to keep out rain, and then it is properly ventilated. Or a door
should be kept opened into a hall with an open window. Let the
bed-clothing be increased, so as to keep warm in bed, and protect the
head also, and then the more air comes into a sleeping-room the better
for health.
