essential to air, to sun, and to clean rooms while uninhabited; which is
simply ignoring the first elementary notion of sanitary things, and
laying the ground ready for all kinds of diseases.--3. That the window,
and one window, is considered enough to air a room. Have you never
observed that any room without a fire-place is always close? And, if you
have a fire-place, would you cram it up not only with a chimney-board,
but perhaps with a great wisp of brown paper, in the throat of the
chimney--to prevent the soot from coming down, you say? If your chimney
is foul, sweep it; but don't expect that you can ever air a room with
only one aperture; don't suppose that to shut up a room is the way to
keep it clean. It is the best way to foul the room and all that is in
it. Don't imagine that if you, who are in charge, don't look to all
these things yourself, those under you will be more careful than you
are. It appears as if the part of a mistress now is to complain of her
servants, and to accept their excuses--not to show them how there need
be neither complaints made nor excuses.

[Sidenote: Head in charge must see to House Hygiene, not do it herself.]

But again, to look to all these things yourself does not mean to do them
yourself. "I always open the windows," the head in charge often says. If
you do it, it is by so much the better, certainly, than if it were not
done at all. But can you not insure that it is done when not done by
yourself? Can you insure that it is not undone when your back is turned?
This is what being "in charge" means. And a very important meaning it
is, too. The former only implies that just what you can do with your own
hands is done. The latter that what ought to be done is always done.

[Sidenote: Does God think of these things so seriously?]
