long and 1 ft. or more wide, and
about 2-1/2 ft. high. Nail a board, A, Fig. 1, about 8 in. wide
and of the same length as the table, to the table, as shown in the
illustration. Paint the table any color desired.
Purchase a dozen or so battery electric bells (they are cheaper if
bought by the dozen) and screw them to the board, as in Fig. 2.
Arrange the bells in the scale shown at B, Fig. 2. Bore two holes
near the posts of each bell for the wires to pass through.
Buttons for the bells may be purchased, but it is cheaper to make

wood and cut it round, about 2-1/2 in. in diameter and 1/4 in.
thick, Fig. 3, and bore two holes, C and D, through it. Then get
two posts, about 1 in. long, (battery posts will do) and put them
through the holes as in Fig. 4. Cut out a piece of tin, 3/8 in.
wide, punch a hole through it and put in under post E, so that
when it is pressed down, it will touch post F. It may be either
nailed or screwed down.
Make two holes in the table for each button and its wires, as at
H, Fig.
