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 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,
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 tug}, a steam vessel used in towing or propelling
ships.
{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 or a signal. The steam issues from a narrow

and producing sound in the manner of an organ pipe or a
common whistle.
