A pair of old doorbell buttons on a house on the South Side. They have little windows where the name of the occupant to be summoned could be displayed. The similar button on the front door of the Pitt mansion is connected by a wire to an electrically activated clapper in the basement, which beats against a bell after the manner of an alarm clock as long as the button is pressed. This is enough racket to be heard throughout a large house. One does have to warn guests about it, though; otherwise the first political canvasser who shows up will send them running for the exits thinking the fire alarm has gone off.
