The following directions for making a copying pad were sent out for 10 cents each by a young man in Chicago, to those remitting that amount to him, in answer to an ad. he inserted in a number of newspapers covering wide territory:

Take white gelatine, 4 ounces; glycerine 20 ounces. Melt the gelatine in water, then add the glycerine, after warming it, and stir until well mixed. Pour into a pan 10x12 inches square and ¹⁄₂ inch deep. Write your copy on a sheet of paper with ink made of methyl violet, 1 ounce; water, 7 ounces. Put on the stove and heat until dissolved, stirring often. Add hot water, to replace that which evaporates. When dissolved, add 2 ounces of glycerine. Use a new pen in writing. Lay copy face down on the pad, and let it remain two minutes, then take it off. From 50 to 100 copies may be taken by laying blank paper on the impression, and repeating the operation until as many copies as desired have been made. Clean the pad with a wet sponge as soon as you are through copying, and keep it in a dry place.

He sold several thousand copies of these instructions, at 10 cents each, and most of this, of course, was clear profit.
