(2) Dissolve 2ib. of common salt and lib. of sulphate of zinc in two gallons of boiling water. (3) Provide two gallons of skimmed milk. Pour No. 2 into No. 1, then add No. 3 and stir well Formula No. 2.—Slake half a bushel of lime in boiling water and keep it covered while slaking Strain the lime and add to it a solution of one peck of salt dissolved in hot water Boil 31b of rice to a thin paste; dissolve half a pound of powdered Spanish whiting and lib. of clear glue; add these to tho lime and salt; mix thoroughly and allow to stand for four days As this preparation should be applied, it is well to mix it in a pot or kettle that can be heated and moved about conveniently for use, it is best applied with whiteorush brushes, but paint brushes will do if others are not available. Whitewash that contains milk, flour, rice, and glue, should not be used in damp interiors. Whitewash is always applied lightly and not brushed in like paint. Formula No. 3. —Slake half a bushel of lime with hot water, stirring continuously while slaking; strain it and add one peri? of salt dissolved in warm water. The proper consistency for whitewash is a thin paste, and water will have to bo added to secure this consistency after mixing the dissolved salt with the whitewash To each 12 quart pail of white wash composed as above, ndrl a good-sized handful of ultra-marine blue: the cement and blue Portland cement and a teaspoon ful of salt should be added onlv as the whitewash is being used, and f.bonld be j thoroughly stirred into the whitewash, otherwise when applied it will be streaked If there are any pipes or other equip ment in the rooms to bo whitewashed that will rust, do not nso salt in the mixture around tho piping Do not pour on too thick a coat.—just enough to cover the surface in good shape—then allow from one to three days for drying. If you dry the whitewash oat too nnickly. it will flake or brush off very easily; on the other hand, a very slow drving will allow .the water to soak into the wood ami may cause unpleasant odours. Whitewash containing Portland cement must be used without delay.,
