The wire
_c c_, and a similar one at the top of the plate, were passed through a
perforation in the pasteboard, and then passed into the board. Instead
of a pulley, the cord, which was a piece of twine, was passed through a
little staple made of wire and driven into the board. The whole was made
in one or two recesses in school, with such tools and materials as I
could then command. The bell was a common table bell, with a wire
passing through the handle. The whole was attached to such a piece of
pine board as I could get on the occasion. This coarse contrivance was,
for more than a year, the grand regulator of all the movements of the
school.
I afterward caused one to be made in a better manner. The plate was of
tin, gilded, the border and the letters of the inscription being black.
A parlor bell-rope was carried over a brass pulley, and then passed
downward in a groove made in the mahogany board to which the card was
attached.
A little reflection will, however, show the teacher that the form and
construction of the apparatus for marking the times of study and of rest
may be greatly varied. The chief point is simply to secure the
_principle_ of whispering at definite and limited times, and at those
alone. If such an arrangement is adopted, and carried faithfully into
effect, it will be found to relieve the teacher of more than half of the
confusion and perplexity which would otherwise be his hourly lot.
