he latter was pasted
to the metal, and trim off the surplus metal where the tacks had
been placed. File off any sharpness so that the hand may not be
injured in handling it. Place the metal on the edge of a table or
between two boards, and bend on the two lines indicated in the
drawing, to right angles.

A good finish is obtained by just letting the copper age with its
natural color. If any polishing is required, it should be done
before the metal is fastened to the board and pierced.

** Imitating Ground Glass [294]

Make a mixture of white lead in oil, 1 part; varnish, 3/4 part;
turpentine, 1/4 part, and add sugar of lead as a dryer. Make a
very thin paint of this and use a broad, flat brush, says Master
Painter. With care you may succeed in getting the paint on quite
evenly all over, which is desirable. One coat will do. If it
becomes necessary to remove this coating for renewal, it may be
effected by an application of potash lye, or the old may be
renewed by a coating of a mixture of 2 parts hydrochloric acid, 2
parts white vitriol, 1 part sulphate of copper (blue vitriol) and
1 part of gum arabic, applied by means of a brush.

** Draw before Cutting [294]

A detail drawing made of a piece of furniture before starting the
work will often save time and mistakes.

** Making "Spirits" Play a Violin [295]

A very pretty trick, that can be worked in your own parlor, will
produce as much sensation as a fake "medium." In all appearance, a
violin, mandolin or guitar, placed on a table, will begin to
produce music simply through stamping the foot and a few passes of
the hand. The music will not sound natural, but weird and distant.

The trick is done by placing the end of a small stick on a music
box in the basement of the house and allowing the other end to
pass up through the floor and table top so it will project about
1/16 in. The stick may be placed by the side of, behind or through
the center of a table leg. Be careful not to have any obstruction
in the way of the stick. The instrument is placed sideways on the
protruding end of the stick. The "fake" work of invoking the
"spirit" is performed and ended by stamping the foot, which
signals the operator in the basement to start the machine, and the
violin seemingly produces music without anyone touching it.

So impressive are the results, that many people really think the
spirits of the departed are playing the violin with unseen hands.
