The Most Economical Soap.
Soap may be two-thirds water and still remain solid. Even dry, hard soap contains 20 or 25 per cent. of moisture. An excess of water causes soap to waste or dissolve too freely in use; hence, as soap is perpetually losing water by evaporation, the most economical to buy is that with some age and moderately dry, yet not so much dried that it will not dissolve readily and make a good lather or suds.
