The white paper is only very fine thin writing paper. The black, is soft paper, prepared by being smeared with a composition of grease and plumbago or lampblack: this mixture is allowed to remain on for 12 hours, and the paper is then wiped smooth with a piece of wool or cotton-waste. Place white paper over black, and write with a blunt point.
Boil white paper, or paper cuttings, in water for 5 hours. Pour off the water, pound the pulp in a Wedgwood mortar, and pass through a fine sieve. This powder is employed by the bird stuffers to dust over-the legs of some birds, and the bills of others, to give them a powdery appearance; also to communicate the downy bloom to rough-coated artificial fruit, and other purposes of a similar nature; it makes excellent pounce.
