SUBMARINE CRAFT
They Surpass All Warships In
Concentrated Deadly Power.
A DIVE UNDER THE SURFACE.
The Terrifying Sensation and the
Agony of Roaring Noises That Be-
wilder the Novice as the Vessel Goes
Down Into the Depths of the Sea.

In waters where the United States
maintains naval station you may
happen to see a tall staff cutting
through the water as though borne by
some unseen hand beneath the sur
face. On the top of the staff is a
slight bent hood pointed in the direc
ton of motion. This is the eye of a
submarine.
From the lens In the front of the
hood d picture of the whole seascape
Is carried down by a succession of
mirrors In the hollow staff until 1t is
thrown on a prismatic lens at the bot.
tom. Here the navigator of the sub
marine watches a moving picture of
what is going on above the surface OF
the water and guides his boat accord
ingly.
We said boat adyisedly, because 1t is
really vessel for the transportation
of human beings at sea. 1t is, more
over. more than a floating craft, swim
ming on the surface like a swan. 1t
is also a diver, darting down into the
depths like a fish.
Let yourself be shut up in it and
dive with it and it seems more like q
tightly corked bottle Your first sen
sation as the boat starts downward is
that you have foolishly allowed your
self to be shut up in death trap

heart sinks faster than the boat
And then something happens to make
you forget everything hut that this
craft is a hellish contriyance for de
stroying your hearing. AS the subma-
rine dips under the surface and all
outlet for sound is cut off by the seal

/ the steel walls becomes the rattle OF
spring hall on tin roof. You remem
ber that Old and painful swimming
! hole experiment when you held your
head under water and let playmate
strike two stones together But here
the assault on your eardrums is as
though million stones were striking
together A pebble falling through the
waters on the steel hull sets the inside
changing like. Chinese temple full OF
1anging gongs You must shout to
be heard
Through the roar from the vibrations
of the steel shell come the fnsistent
cracking hum OF electric motors, the
rafting fire of gasoline engines, the
whir of machinery and the barking
cough of exhausts. Your craft seems
to be nothing but an elliptical mass OF
concentrated noise sinking through the
sea. You fear that it will blow up
from its own vibrations.
When you have in measure con
trolled your protesting ears you look
around and see wonderful array OF
engines, machinery, deadly torpedoes
iashed together in pairs and the steel
tubes from which they are projected
with compressed air ali slowed away
In the least possible space.
The double walls surrounding you
are themselves huge ballast tanks,
which can be filed with water through
valves opening into the sea outside or
pressed air from within AS these
tanks are filled the hull Of the sub
marine sinks until only the periscope
the elevated eye of the vessel, shows
above the water When the water is
forced out of them the boat becomes
light and rises to the surface until it's
coming tower, superstructure and the
upper part of the hull are exposed.
Then the craft is nayigated like any
other boat
When the vessel is submerged the
navigator at the lower end of the
periscope has far more intricate task
than the steering of an ordinary boat.
The periscope, of course, brings him
g. limited view of the sea about Then
he must steer in two planes instead
of one. His craft turns not only to
the right or left, but also up or down.
To enable the vessel to stay under
the water a longer time than usual
the submarine carries reserve supply
of air. This emergency supply is COM
pressed in a steel flask under the enor-
nous pressure of 1000 pounds to the
square inch. Should the flask burst
the explosion would wreck the boat
Perhaps a better idea of the tremen
dous concentration implied by this
pressure may be gained from the
statement that If this storage cylinder

. For ordinary purposes the air sup
ply used under water is carried in or

sures. Unusual precautions have tx
be taken to prevent the contamination
pf the air supply by gases from the
storage batteries and from the gasoline
motors.
Concentration epitomizes the subma
rine. Its energies and utilities are
packed In like the parts Of puzzle
