Royal Washing Powder
Mix any quantity of Soda Ash with an equal
portion of Carbonate of Soda--ordinary Soda--crushed into coarse
grains. Have a thin solution of Glue, or decoction of Linseed Oil
ready, into which pour the Soda until quite thick. Spread it out on
boards in a warm apartment to dry. As soon as dry, shake up well, so
that it will pack easily into nice square packages. Label neatly. Pound
packages cost seven cents; retails for thirty-five cents.
