      which the hot gases, from the fire beneath the boiler,
      enter, after traversing the outside of the shell, and
      through which the gases are led to the smoke pipe d, which

   {Steam gauge}, an instrument for indicating the pressure of

      bent tube partially filled with mercury, one end of which
      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 tume 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,
      closed at one end, which the entering steam tends to
      straighten, or it may be a diaphragm of elastic metal, or
      a mass of confined air, etc.

   {Steam vessel}, a vessel propelled by steam; a steamboat or
      steamship; -- a steamer.

   {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 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
      common whistle.
