Rubber Hand Stamps and the Manipulation of Rubber

The articles produced are of more than ordinary utility. These two facts give value to the art and furnish a raison d’être for this book. If its instructions do not prove practical it will have missed its object. The allied subjects to which some chapters are devoted will be acceptable to many readers. The hektograph is given in several modifications. A substitute for rubber stamps which stands the severe usage of the Post Office has very distinct merits, and the manufacture is accordingly described in detail. Cements and inks embody many special formulæ. In the last chapter interesting and practical notes will be found.
