These directions are given by Prof. Turner, of the American Asylum for the Deaf and Dumb, as follows:
- Take 5 pounds of Paris white, 1 pound of Wheat flour, wet with water, and knead it well; make it so stiff that it will not stick to the table, but not so stiff as to crumble and fall to pieces when it is rolled under the hand.
- To roll our the crayons to the proper size, two boards are needed, one to roll them on; the other to roll them with. The first should be a smooth pine board three feet long and nine inches wide. The other should also be pine, a foot long and nine inches wide, having nailed on the under side near each edge a slip of wood one-third of an inch thick, in order to raise it so much above the under board as that the crayon, when brought to its proper size, may lie between them without being flattened.
- The mass is rolled into a ball, and slices are cut from one side of it about one-third of an inch thick: these slices are again cut into strips about four inches long and one-third of an inch wide, and rolled separately between these boards until smooth and round.
- Near at hand should be another board 3 feet long and 4 inches wide, across which each crayon, as it is made, should be laid, so that the ends may project on each side--the crayons should be laid in close contact, and straight. When the board is filled, the ends should all be trimmed off so as to make the crayons as long as the width of the board. It is then laid in the sun, if in hot weather, or if in winter, near a stove or fireplace, where the crayons may dry gradually, which will require twelve hours. When thoroughly dry they are fit for use.
An experienced hand will make 150 in an hour." Young boys can make them and sell to their companions.
