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.
