The hooks which serve as legs are
fastened to the under side of the board in the same manner as
fastening the hook to a wall.

** A Line Harmonograph [34]
[Illustration: Harmonograph]
As an apparatus capable of exciting interest, probably nothing so
easily constructed surpasses the harmonograph. Your attention will
be completely absorbed in the ever changing, graceful sweep of the
long pendulum, the gyrations of which are faithfully recorded in
the resulting harmonogram.
A careless impetus given to the pendulum may result in a very
beautiful harmonogram, but you may try innumerable times to
duplicate this chance record without success. No two hamonograms
are exactly alike. The harmonograph, while its pendulum swings in
accordance with well known natural laws, is exceedingly erratic
when it comes to obeying any preconceived calculations of its
operator. In this uncertainty lies the charm. If time hangs
heavily or a person is slightly nervous or uneasy, a harmonograph
is a good prescription.
