Weak eyes should always be especially
shaded from the lights. Small screens, made for the purpose, should
be kept at hand. A person with weak eyes can use them safely much
longer when they are protected from the glare of the light. Fill the
entry-lamp every day, and cleanse and fill night-lanterns twice a week,
if used often. A good night-lamp is made with a small one-wicked lamp
and a roll of tin to set over it. Have some holes made in the bottom
of this cover, and it can then be used to heat articles. Very cheap
floating tapers can he bought to burn in a teacup of oil through the
night.
TO MAKE CANDLES.
The nicest candles are those run in moulds. For this purpose, melt
together one quarter of a pound of white wax, one quarter of an ounce
of camphor, two ounces of alum, and ten ounces of suet or mutton-tallow.
Soak the wicks in lime-water and saltpetre, and when dry, fix them in
the moulds and pour in the melted tallow. Let them remain one night
to cool; then warm them a little to loosen them, draw them out, and
when they are hard, put them in a box in a dry and cool place.
To make dipped candles, cut the wicks of the right length, double them
over rods, and twist them.
