        is connected with the boiler while the other is open to
        the air, so that the steam by its pressure raises the
        mercury in the long limb of the tube to a height
        proportioned to that pressure. A more common form,
        especially for high pressures, consists of a spring
        pressed upon by the steam, and connected with the pointer
        of a dial. The spring may be a flattened, bent tube,

     Steam whistle, an apparatus attached to a steam boiler, as
        of a locomotive, through which steam is rapidly
        discharged, producing a loud whistle which serves as a
        warning or a signal. The steam issues from a narrow
        annular orifice around the upper edge of the lower cup or
        hemisphere, striking the thin edge of the bell above it,
        and producing sound in the manner of an organ pipe or a
