Where there are large flights of stone steps and broad pavements of flag-stones, the process of cleaning is a tedious one. To clean with hearthstone, or caked whiting, as usual, gives a smeary appearance, and washes off with the first shower. The following preparation is preferable alike for its appearance and as a labor-saving appliance, as it need be used but twice a week, washing being sufficient for the remaining days : Take a gallon of water, and color with stone-blue to a deep tint. Boil in this a pound of white size, and dissolve in the mixture a quarter pound of whiting and three cakes of pipe-clay, stirring well. Wash the steps rapidly with this solution, and finish with clean water in the usual way.
