=Whitewashes=: Either glue or vegetable size may be the foundation. Add a big lump of salt to five gallons of size, stir well, and pour boiling hot upon half a peck of unslaked lime. Clear with Prussian blue and apply very hot. For sanitary carbolic whitewash use vegetable size, dissolving in five gallons, boiling hot, two ounces of carbolic crystals. Then pour upon the lime and mix well. Two ounces of copperas—green vitriol—dissolved instead of the carbolic acid gives a faint-yellow tinge and is a good prophylactic. To kill vermin, as in poultry houses, nest boxes, and so on, mix through a pail of hot wash five grains of corrosive sublimate dissolved in a pint of water; put on as a first coat, and after a while give a second coat of plain whitewash. =Milk Whitewash=: Stir into a gallon of sweet milk enough unslaked lime in fine powder to make it thicker than cream. Add a teacup of turpentine, stir well, and put on at once with a paint brush. This sticks to smooth wood nearly the same as paint, and can be colored with earth paints almost any shade. =Paste for Paper-hanging=: Wet up smooth in cold water two tablespoonfuls of flour and stir it into a gallon of water on the bubbling boil. Stir hard to prevent lumps, add a small spoonful of tallow, cook for several minutes, then add an ounce of alum dissolved in half a pint of boiling water. Take from fire and add ten drops oil of cloves. =White Mucilage=: For mending books and making scrap books. Cover clean gum tragacanth with cold water, let stand till dissolved, then add oil of cloves to keep from molding. Keep in a glass jar tightly closed. This leaves no mark. =Gum Arabic=: For clear starching and shirt bosoms. Get four ounces of dry gum, pick over carefully, throwing out dark pieces and blowing away dust. Pour upon it a pint of boiling water, let stand till dissolved, filter, and bottle. A tablespoonful added to a quart of starch gives a high gloss. Two spoonfuls in a quart of tepid water will stiffen fine lawn or muslin sufficiently and restore the new look. =Paper Dough=: Crumple newspaper very soft, tear to bits, dampen, pound, and knead well, then wet with strong glue size and knead to a dough. For wall breaks, rat holes, filling yawning cracks, or rounding corners, mix in plaster of Paris at the moment of application and pound in place before the plaster sets. Mix only what can be used at once. =White Cement=: Mix sifted whiting to a soft dough with white of egg, for filling small holes in white walls or cracks in ceilings. Press in with a blunt knife and smooth the surface with the blade dipped in cold water. =Sand and Plaster=: Sift together fine sand and plaster, wet with hot water, and use to fill bigger breaks in a wall. Wet only a little at a time and work quickly. Lay a board over the mortar as soon as in place, and beat with a hammer to smooth.
