To Find the Lay of the Pages in a Half-Sheet Form.— Fold a sheet to double the number of pages, page backwards on one side of the sheet only; open out, and the pages will appear in their proper position. One form thus arranged, when printed on both sides of the sheet, gives two perfect copies.

Postage Stamp Gum.—The Scientific American says:—The following cheap recipe for the mucilage used on postage stamps may be useful for many purposes: Gum dextrine, two parts; acetic acid, one part; water, five parts; dissolved in a water bath, and one part of alcohol added.

Tea in Lithography.—The American Lithographer has awarded a $100 prize for this « wrinkle »—to use strong tea to keep the zinc surface or lithographic stone clean. The discovery was accidentally made. Tea contains from 6 to 12 per cent. of tannic acid, which is supposed to be the active agent. It is scarcely necessary to add that milk and sugar are not required. It is a curious fact that the agents most in favor for this purpose hitherto have been either tobacco or beer; but tea has proved to be superior to either.

Leather for Tint Blocks.—A correspondent of the Inland Printer sends some good specimens of tint-work, printed from a surface of patent leather glued to a wooden block, and cut with a pen-knife. One of these ran 25,000 impressions, with scarcely any perceptible wear. To offset the pattern, he took an impression in ink, and bronzed it over. He also produced good results by pressing lace and similar materials into the face of the leather with a heated iron.
