two hulls, one, the outer, having the lines OF
torpedo boat. The high freeboard and super
structure Of this hull serve to make the boat ex'
tremey seaworthy. The inner hull fits under the
outer ike boiler under the water tank OF

long boiler, and is something more than twelve
feet in diameter It is the practice at the present
stage of the development of the submarine 70
equip them with gasolene or Diesel engines and
electric motors The latter are placed on tho
shafts of the oil engines, which are used when
the vessel is awash or running on the surface.
They are then employed TO develop current, which
is stored in accumulators for when below the
surface where the oil engines cannot be run
Then the latter are disconnected and the current
turned into the generators, which now beooms
motors The engine room is placed aft Forward
Of il are the internal water ballast tanks, and
amidships is the coming tower, in which are To-
Gated the levers and other devices for controlling
the movements Of the boat. The quarters OF the
officers are in the tower, tho crew and the galley
being accommodated forward. The periscopes,
two in number, rise close together from the con-
ming tower. They are sixteen and one-half feet
high. By means Of mirrors objects on the sur
face are reflected to the commander In the con-
ming tower when the vessel Is submerged. This
guides him in approaching the enemy and dis
charging the torpedo. However, if both Of the
tubes of the periscope should by any chance be
observed and under an unusually fine display OF
craftsmanship be actually cut off, the gyroscope
compass which the Germans have devised can DC
used for taking the submarine her prescribed
course.
Great pains have been taken TO secure an ade-
1uate ventilation of the vessel The heated air OF
the engine room and the exhaled air of the crew
are drawn off, filtered, oxygenated and cooled.
after which it is returned to the interior It Ia de-
clared that one Of these submarines could remain
below the furface for twenty-four hours without
Inconvenience TO the crew. Provision is made for
emptyng the water ballast tanks and filing them
with air from the bountiful supply of compressed
air which is carried The she'll is OF sufficient
strength to withstand safely the pressure Of water
to be found at a depth Of 2951l feet The space
between the outer and inner hulls is subdivded
into number Of watertight compartments which
contribute greatly to the safety Of the vessel, for
a number Of them can be puncturel without
dangering the boats ability to float In this
space also are carried the water ballast, oil and
gasolene tanks. The boat descends and rises
through the action Of a pair Of horizontal rud-
ders, one on either side The operation OF these
enables the craft TO maintain constant level Of
submersion below the surface

as il submarines might be depended upon in the
future for coast defence and cruisers for the de-
struction Of the commerce Of the enemy. Beyond
this there would be no need for armed naval yes
sells. What saving in taxes such programme
would accomplish
