An Ocean Steamer a Thousand Feet
Long.

Long.
The plans of men of ideas of these
days Of large projects on sea and land
create no surprise, but those of Darius
DAWSON for a 1000 foot vessel to carry
passengers and freight is ahead of any
thing yet proposed by marine archi-
tects or proposed by practical builders.
There is in his scheme, however, so
much that, to the lay mind as well as
the scientific expert, appears worthy Of
trial that he has found many advocates
who are warmly seconding his efforts
to build new ocean greyhound. He
is now organizing company, says the
New York Herald, to put his plans
into execution. Should they be carried
out with success the recent trials of the
Paris and Campania would sink into
insignificance.
Mr.. Dawson was ahead of the whale
back steamers with suggestions that
are apparent in their construction.
These ideas are carried out in the
plans of a vessel that have been pre-
pared by Mr.. Dawson. There are
embraced in the construction and
equipment Of the Leviathan ten inven-
tons and Improvements, including +:
Model and combined proportions of
the hull mechanical construction of
the hull, steam generators, steam ma
chinery, construction and adoption of
propellers, improved crank shafts, i'm
proved ventilating machinery and pro-
cesses, improved method of stocking
fires and improved steering and rud-
ders.
These inventions and improvements
embrace all the important changes that
can be made to practically perfect
steam vessels and steam navigation,
used separately or all combined, in a
vessel as a completed whole
In prospectus Dawson has issued
he gives the following dimensions of
the vessel:

The 10000 horse steam power to be
used on this vessel to run at speed OF
thirty miles an hour, says the pro.
spectus, will be produced by methods
never before used, demonstrating that
one fifth the amount of fuel now con
sumed will generate and maintain con
tinuously that amount of power anc
utilize to the fullest extent the expan
sive force of high pressure dry steam
with rapid travel of piston, taking ad
vantage of novel and scientific device!
to relieve the cranks, shafts and pin!
from the chief part of the unnecessary
strain now thrown upon them witt
engines of great power when run at ;
high speed.
There will be in this vessel four sep
arate sets of reciprocating, vertical
direct acting engines in separate water
tight compartments, easily accessible
adding materially to the safety of thu
vessel, constructed and operated or
new principles, capable of permitting
the engines to run at a high speed, i'm
practicable in engines of great powe
by any of the present methods of con
struction and operation.
There will be four propellers up "
the Leviathan Of improved construc
ton and adaptation to the exterior @
the vessel, SO placed as not to interior
with each other in their action and ais
avoid the loss of prupelling force whic
now pertain to all propelers by indirec
action and otherwise as at present con
structed and adapted to all vessels
They will at all times, in a smooth c
rough sea, be immersed in deep, soil
water, and thus avoid racing.
The immersed side surface of TIL
vessel by its length relative to il
breadth gives an angle of divergenc
