TO SOFTEN HARD WATER.
The "hardness" of water arises from the presence of lime. It may be overcome in the following manner: For every gallon of water to be softened, dissolve half an ounce of washing soda in a small quantity of hot water, stirring well. Put this mixture into the hard water and stir freely for a few minutes. Let' the whole stand # for twenty-four hours; the soda and lime will both sink to the bottom, forming a sediment there, and leaving the water soft. The softened water should' be taken' away without -disturbing the sediment; for this purpose it is well to have a tap some distance from the bottom of the' vessel, and as soon as the vessel is empty as low as the tap the remainder should be let out, with the sediment, through a plug-hole in the bottom and thrown away,
