SPECIAL KINDS OF PAINT Lime Paint.—A mixture combining the qualities of paint with those of whitewash may be made with slaked lime as a basis by the addition of various materials, as milk, whiting, salt, alum, copperas, potash, ashes, sand, and pitch, with or without a small proportion of white lead and linseed oil. These mixtures are more durable than whitewash, but have less finish than white lead and oil. The cost is intermediate between the two.
To prepare a lime paint, slake lime with water and lct dry to the consistency of paste. Thin with PkilnMeti Milk to the proper thia ness to lay on with a brush. Add coloring matter as desired.

Two or three coats will be necessary. The above quantity is sufficient for 100 square yards.
Or slake stone lime in a cask or barrel with boiling water. Cover it to keep in the steam. Sift 6 quarts through cheese cloth or a fine sieve, add 1 quart of coarse salt and 1 gallon of water.
