Heat the water to boiling hot, put in the soda, boil about five minutes, then pour it over the unslaked lime, let it bubble and foam until it settles, turn it off and bottle it for use. This is the article that is used in the Chinese laundries for whitening their linen, and is called "Javelle water;" a tablespoonful put into a suds of three gallons, and a little, say a quarter of a cupful, in the boiler when boiling the clothes, makes them very white and clear. Must be well rinsed afterwards. This preparation will remove tea stains and almost all ordinary stains of fruit, grass, etc. This fluid brightens the colors of colored clothes, does not rot them, but should not be left long in any water; the boiling, sudsing, rinsing and bluing, should be done in quick succession, until the clothes are ready to hang on the line.
