of the cellar is of the greatest importance, and should never be
neglected.

One of the most noted authorities in America, on the question of
ventilation, says: "The three important objects are, (1) To provide an
abundance of pure air in every part of the house; (2) To avoid drafts,
either hot or cold; (3) To provide means of escape for foul air and
odors." As before stated, much of the vigor, comfort and happiness of
the family depends upon attention to these matters. Next to the
cellar, we will take the living and sleeping rooms, which should be
thoroughly aired every day, not simply by opening the window a few
inches at the bottom, or--as in some double or outside windows--by a
little opening a few inches wide; but by causing a circulation of air
in the room, and providing an outlet for foul air near the ceiling,
which may be done by lowering the window from the top. An outlet for
foul air is quite as important as an inlet for fresh air.

If there is a skylight at the top of the house, it should be kept open
a few inches all the time as an outlet for impure air; an attic window
will serve the same purpose. Have doors and windows so arranged that a
draft may be made possible when needed to change the air of a room
quickly, or in airing bedclothes; two windows being of course more
desirable. After dressing in the morning, open the window of the
sleeping room, top and bottom; turn back the clothes over one or two
chairs; place pillows and mattress where they will have a current of
fresh air; also open the closet door. Do not allow water to remain in
a bedroom more than twenty-four hours.

When a sleeping room has been used for a sewing or sitting room during
the day, it should be thoroughly aired before bedtime. Open the
