should be thoroughly scrubbed with borax or sal-soda and water, and well
aired, at least once a week. Strongly flavored foods and milk should not
be kept in the same refrigerator. The ice to be used should always be
carefully washed before putting in the refrigerator. Care should also be
taken to replenish it before the previous supply is entirely melted, as
the temperature rises when the ice becomes low, and double the quantity
will be required to cool the refrigerator that would be necessary to
keep it of uniform temperature if added before the ice was entirely out.

THE WATER SUPPLY.--The water used for drinking and cooking purposes
should receive equal consideration with the food supply, and from
whatever source obtained, it should be frequently tested for impurities,
since that which looks the most refreshing may be contaminated with
organic poison of the most treacherous character.

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
