A good and simple test solution, which any housewife can use, may be
prepared by dissolving twelve grains of caustic potash and three of
permanganate of potash in an ounce of distilled water, or filtered soft
water. Add a drop of this solution to a glass of the water to be tested.
If the pink color imparted by the solution disappears at once, add
another drop of the solution, and continue adding drop by drop until the
pink color will remain for half an hour or more. The amount of the
solution necessary to security permanent color is very fair index to the
quality of the water. If the color imparted by the first one or two
drops disappears within a half hour, the water should be rejected as
probably dangerous. Water which is suspected of being impure may be
rendered safe by boiling. Filters are only of service in removing
suspended particles and the unpleasant taste of rain water; a really
dangerous water is not rendered safe by filtering in the ordinary
manner.
CELLARS.--Sanitarians tell us that cellars should never be built
under dwelling houses. Because of improper construction and neglect,
they are undoubtedly the cause of much disease and many deaths. A
basement beneath the house is advantageous, but the greatest of care
should be given to construct it in accord with sanitary laws. It should
be thoroughly drained that there may be no source of dampness, but
should not be connected with a sewer or a cesspool. It should have walls
so made as to be impervious to air and water. An ordinary brick or stone
wall is inefficient unless well covered with good Portland cement
polished smooth. The floors should likewise be covered with cement,
otherwise the cellar is likely to be filled with impure air derived from
the soil, commonly spoken of as "ground air," and which offers a
constant menace to the health of those who live over cellars with
uncemented walls and floors.
Light and ventilation are quite as essential to the healthfulness of a
cellar as to other rooms of the dwelling. Constantly during warm
weather, and at least once a day during the winter season, windows
should be opened wide, thus effecting a free interchange of air. All
mold and mustiness should be kept out by thorough ventilation and
frequent coats of whitewash to the walls. Vegetables and other
decomposable articles, if stored in the basement, should be frequently
sorted, and all decaying substances promptly removed. This is
