Book marks are very handy to have on one's desk. They are easily made and if very light copper is used need not be heavy or clumsy. They should be made very smooth, for they must slip easily into place in the book.
Material: No. 30 copper, 3 × 3⁄4 in. Directions: This drawing can be used as the guide. Make it the required size and work just as you did when making the paper cutter. The little tongue on the inside is sawed out. It should swing easily to and fro, as it must be pushed open to catch the pages of a book and clamp them down. File and finish very smooth. If it is left the least bit rough it would tear the paper as it is pushed in.
BRASS WORK

Brass: Brass is an alloy of copper and zinc. The zinc colours the copper and gives it the yellowish or brassy look, depending upon the amount of zinc melted with it. While the operations are the same whether you are working with brass, copper, or silver, the presence of the zinc in brass makes it less pliable than the pure metals. That is why brass hardens so quickly under hammering, making it necessary to anneal the metal very often in order to work it. But zinc and copper combined melt at a lower temperature than copper or silver pure, so that great care must be taken when preparing the metal for soldering or annealing that you do not heat it over a dull red heat before plunging it into water.
