Burning, (To Protect Children From). Add one ounce of alum to the last water used to rinse children's dresses, and they will be rendered uninflammable, or so slightly combustible that they would take fire very slowly, if at all, and would not flame. This is a simple precaution, which may be adopted in families of children. Bed-curtains, and linen in general, may also be treated in the same way.
