Place one gallon of good soft soap in a kettle to boil; when it begins to boil, stir in a pint measure level full of common salt, stirring it all the time until the salt is dissolved, then set to cool. Next day, cutout the soap in squares, scrape off the soft, dark part, that adheres to the lower side of the cakes, pour out the lye, and wash the kettle, place the soap, cut in thin slices in the kettle, with more weak lye. If the lye is strong add rain-water, pint for pint; let it boil until the soap is dissolved. While boiling, again stir in a pint measure level full of salt, stirring it some as before, and set to cool. When perfectly hard, cut it in cakes the size you wish, scraping off the soft lye part that adheres to the lower side, and lay on boards, top side down in the sun, turning it each day until sufficiently dry. Or, if you wish to make a twelve or fourteen gallon kettle of soft soap into hard, three quarts of salt, stirred in each time, will he sufficient. But as soap differs in strength, the quantity of salt most also differ. The stronger the soap the more salt is required. A good general rule is our old grandmother's: "When the soap is boiling, stir in salt until it curdles and becomes whitish in color." It can he tested by placing some in a shallow pan to cool, as it cools in a few minutes sufficiently to know if enough salt is in.
