knowledge of the laws of sanitation, and are coming to understand that
cleanliness consists in something more than scrubbing the floors and
washing the windows. Hence the following hint: A barrel each of lime and
charcoal in the cellar will tend to keep that part of the house dry and
sweet. A bowl of lime in a damp closet will dry and sweeten it. A dish
of charcoal in a closet or refrigerator will do much toward making these
places sweet. The power of charcoal to absorb odors is much greater
directly after it has been burned than when it has been exposed to the
air for a length of time. Charcoal may be purified and used again by
heating it to a red heat. The lime must be kept in a place where there
is no danger of its getting wet, and not exposed to the air.
