death would never know what had be-
fallen them, whether their own boilers
or their own magazine had blown up,
unless the submarine yacht rose to the
surface and fshed them out of the
water and the wild chaos of tossing
wreckage which in few moments would
be all that would be left of their ship. II
the vessel attacked were of a fleet
her fate would be rs much mystery
to those on board her sister ships rs to
her own Grew. There would be q dull,
smothered explosion, lifting of the
huge mass of metal heavily upward,
then staggering, headlons lunge into
the depths of the sea and the tossing
arms of those not dragged underneath
by the suction MS the ponderous mass
sunk out of sight.
On board the submarine yacht the
spectacle would be even more thrilling
than from the decks of vessels on the
surface of the water. After hurting
its torpedo low down against the ex-
posed flank of the enemy there would
be q reversal and swift whirling of the
twin screws until the vicious little
craft had darted back to safe dis
tance from the concussion and the
the 4aoofhlt qh# e!h's
ICY gs:8essmcers and crew, with their cleo
trio search lights turned on the scene
and the steel panels slid back from be-
fore her broad plate-glass window,
could watch at their leisure every de-
tail of the death agonies of sinking
ship and drowning men.
But aside from nil mere anticipatory
speculations rs to what it may accom-
plish in actual warfare, Mr.. Dantz-
becher's submarine yacht is fast as
suming the proportions of q practical
business investment. It's details have
all been carefully worked out and the
plans drawn. The boat will be 100
feet long over all and twelve feet in
diameter at the midship section.
1t is cigar-shaped cylinder in form,
for the reason that the cylinder will
best resist the pressure of the water,
which at a depth of ninety feet is thirty
nine pounds to the square inch. When
submerged there will be displace-
ment of 169 TONS The plating in the
middle fifty feet of length is half inch
of mild steel, with thickness Of three
eights of nh inch at the ends.
"The diving apparatus of the boat, "
said Mr.. Dantzbecher in recent in
terview, els radically different from
anything yet constructed, and is cop
led from the fish. There is shaft ex-
tending athwartships and going two
feet beyond the hull, to which are at
tached the diving planes, which are
horizontal rudders, placed one on each
side and two feet wide by ten feet long,
located about twenty feet from the
bow. There is also duplicate set OF
these planes about the same distance
from the stern, and so designed that
they may be worked independently OF
together. A fish balances in the
water, and rises, falls or maintains his
level by the use of the two fins placed
just back of his gills. This is TACT
of which any one may convince himself
by watching goldfish in an aquarium.
"These diving planes, placed fore
and aft. will in the same way control
the depth of the hull in the water, a
set of levers in connection with cylln'
ders either elevating or depressing
them for rising or falling in the water,
and so arranged that the pressure OF
water outside of the hull makes it au'
tomato in operation and keeps the
boat on an even keel at NIL times at any
desired depth.
There will always be maintained q
reserve buoyancy of from 700 to lOOC
pounds, so that should the machinery
in any way become disarranged the
hull will at once come to the surface.
''The boats air tanks will be con-
structed for pressure of 1000 pounds
and ventilation is provided Tor by
blowers and pumps, which exhaust the
impure air to one compartment, where
it is pumped overheard, and the prop
erly regulated supply from the tanks
will keep the mir pure.
''The boat will be driven by two gas
engines of eighty horsepower each'
direct connection, each engine having
two cylinders. This gas-power engine
is used because it keeps all fire from
the hold, the gas in the engines being
made from gasoline and exploded by
electric spark from the storage battery
plant. The engines will exhaust
when on the surface, to the open air
but when running submerged will ex
haust into condenser, and the case:
of exhaust will then be discharged
outboard by the vacuum pump. They
will also be made to disconnect from
the driving shaft, and one will b'
utilized to run the dynamo and th'
other to furnish power for the air com
pressor. -
