T1RPEDO BOAT

lRREDO BO4T
Forward, under the deck. are the
huge gasoline tanks, holding 5000 gal
Ions of this highly explosive fuel.
Amidships and under foot are the great
STORAGE batteries. Aft is the propelling
machinery. the electric motors for
driving the screw while submerged
and steering, the six-cylinder gasoline
motor of 500-horse power, used in OPP
eYsting when on the surface; the dy
namos for charging the batteries and
the air compressor. All these were all
right when the crew left the night be-
fore, but machinery sometimes does
strange things over night, and each
part is looked over carefully.
Meanwhile, from the coming tower
or from the deck, the commanding of
f1cer is directing the boats course by
the aid of an instrument about the size
of dollar watch, which at a distance
il much resembles. On it are buttons
for signals to the engines and two
more to steer by. Pressure on one
sends the boat to port, on the other to
starboard When neither is pressed
the vessel goes on a straight course,
This watchlike affair controls the cleo
trio motor which operates the steering.
gear. and a long flexible cable makes
it possible to steer from any part of
the boat
When the point at which it is de-
cided to submerge is reached water is
gradually admitted to the tanks in the
boat and she settles until she is awash.
The matches have previously been
tightly closed, then the coming tower
is closed and made tight and a sea-
man takes the electric steering device,
while his officer goes below to direct
the work of submerging. In his posi-
ton amidship he has his periscope di-
rectly in front of him. To his left are
gauges showing the angle of the diving
rudder as well as the wheel by which
it is operated and two large dials
showing depth of water. Forward and
on either side men are stationed at
valves.
The first thing done is to trim the
boat-that is to say, get her balanced
on an even keel, that she may be
handled properly. Water is slowly adj
mitted to the main tank, then to the
trimming or balancing tanks. Some
times too much is taken in Then the
excess is blown out by air under 1000
pounds pressure until the exact bal
ance is acquired.
To those in the boat there is re-
markable lack of movement, of vibra-
ton there is very little. One feels that
he is in a room without windows, and
when the lights out" order comes
the sensation is exactly the same as
when one finds himself suddenly left
in darkness in strange house. The
whining of the engines alone gives
evidence of life about, and one is glad
when the current is turned on again.
1t is cool in the boat, too, so cool that
the hull begins to sweat great drops of
water that landing on nervous mans
neck makes him shiver.
After a few miles under water the
orders necessary to rise are given.
First water is blown from one tank,
then from another, till at last the top
of the periscope is above the water.
Below, by its aid, the officer has
clear view of all about him.
Often these trips consume hours.

quented by commerce to point as far
away as Brenton's reef and return
with only an occasional rise to use the
periscope On these trips he never
had an accident, though at times the
channel on the surface was filled with
sailing vessels.
The dip beneath the surface, how
ever, is by no means the end of the
crews work for the day. They must
make ready for the next dive, for on
the trip the storage batteries have be-
come nearly, if not quite, exhausted.
