or b,OOO horse power IN all
Two auxiliary high-ptessuTe condensing en-.
gines are fixed adjacent 70 the paddle engines
foE working pumps aud other necessary work of
the ship. These two engines together are equal
TO 60 horse power when working at 40 pounds,
though, as they arc made TO work at 90 pounds,
their power can be doubled II necessary.
The screw engines consist Of four cylinders
Of 81 inches diameter and four feet stroke, work.
ing horizontally As with the paddle cy finders,
each of the four is in itself a complete and sep
arate engine capable OF working quite inde-
pendently Of any OF the other three They
work up to an indicator of power OF 4 500 horses
Of 80, 600 pounds, when working at as strokes
minute, with steam ia the boiler at L pounds,
and the expansion valve cutting off at one third
of the stroke, They are, however made 10
work smoothly either at forty strokes per min
ute, with steam at rs pounds, without expan.
siou, OF at So strokes a minute with the eIpan-
sion cutting of at ono-fourth of the stroke -
Under these circumstances they will be working
at the tremendous power of {, 800 horses The
boilere, Of course, arc Of the same kind as the
paddle boilers, only ten in number. Connected
with the screw engines are two auxiliary high
pressure engines Of seventy horse power, work
ing with forty pounds, but with these as with
the other auxiliary engines, are made 20 work
at sixty pounds. Both these, besdes doing
ordinary ships work, are connected with the
screw shaft aball tho ordinary disconnecting
apparatus, so as TO enable them TO drive the
screw il necessary, when disconnected from its
main engine. It will thus be seen that the
paddle and screw engines, when working to-
gether at their highest power, will exert an
effective force Of not less than IL, 500 horse
power.
SAILING PowHE--NAsTs AND RIGGING.
In addition to the motive steam power, tho
wind will 10 a considerable extent bo made
available, aud for this purpose the vessel is
provided with six masts. These are OF hollow
wrought iron except the last or mizEen mast
on which at a height Of eighty-fOur feet from
the deck, will DO placed the compasses. Two
of tho masts are square rugged, with iron spars,
except the upper topsai yards The standing
rigging is otwiro rope, aud the large shrouds Of
this material are eight and a half inches in cir.
cumference; instead Of tho ordinary deadoves
aud lanyards, or the right and left hand screw
nyards, an ingenious contrivaneo has been
devised for letting go the shrouds instanta-
neously il any emergency occurs in which il
should ever be required The masts will spread
together no less than $500 tquare yards of
canvas her sails being OF anleficient but simple
character. She carries no bowspnt.
Tho compasses as we have said, will he placed
aloft at height of eighty -four foet ON staging
raised upon the mzzen mast, to remove them
from the disturbing influences inherent in the
vast masses of iron below; and it is proposed
that strong shadows Of the needles shall be
cast down a tubo so that the steersman NAV az
once watch their shadow, and 80 follow directly
the movements of the cOmpasses as they trav
eTse.
Gas will be manufactured on hoard and laid
through all parts of the ship. while by means
of powerful electrical light at her masthead
perpetual moonlight will be diliused around her.
HKR DICKS.
But TO comprehend the immense size of tho
ship ono must 60 ON the main deck, and here IS
one vast area that can bo compared TO nothing
but itself. There is no poop, no "house on
deck" and nothing TO break the great promon-
ade, save the six or seven ma 3ts, and smoke
stacks, the stair cases to the cabins and the sky
lights. Mr.. Russsll says, standing on one OF the
paddle boxCs-"Iero l command the entire
ship" From that standpoint every foot of deck
10 seen except the very shadow of tho masts and
chimneys aud the wave of the hand can he
seen by the steeBman or any officer on watch
on any part Of the deck. Go on TO the bridge
between the paddle boxes and look towards the
bow, and you see a space and extent equal to
that Of the entire length of very large steam
er-near $50 feet-and then turn your owes to.
wards the stern and you have double the dis,
tance in that direction, tho entire length of the
deck being little short OF 700 feet, the width
being 81 feet Our cOuntry readers will apprcs
cate the expanse of deck as about an acre of
surface-or l60 square rods-strotched out into
long oval, one-eighth of mile, or 40 rods ia
length. The deck of the ship is double, OF
cellular, after the plan of the britannia tubular
bridge; and is formed Of two half inch plates
at the bottom and two half-inch plates at the
top, between which arc webs which run the
whole length of the ship,
The deck has boen SO planned as TO be OF
such strength that if il were taken up by its two
extremities and the entire weight the vessel ID
ever to carry were hung upon its middle, il
would sustain the whole by its unaided powers
Of resistance,
The deck is 092 feet IN length, or more than
as long again as that of the steamship Great
Britain it is nearly three times as long as that
OF the British line of battle ship tho Duke of
Wellington; eighty feet more would mako itas
long again as that Of the Persia, at present the
longest vessel afloat upon the ocean.
She carries twenty largo boats on dock, In
addition 10 these sho also OaTries, suspended aft
of her paddle boxes, and hung on davits, two
small screw steamers ono hundred feet long
each, and between sixty and seventy tons bur
then. These arc raised and lowered by the
small auxiliary engines, mentioned as fixed on
board for the purpose ofpumping, hoisting sails
and weighing anchor. Both the little screw
steamers are kept in all respects perfectly
equipped for sea, and ready for the onerous
service Of ombarking and landing tho passen.
gers, with all their luggage, &c, alongside tho
wharf or pier, whichever it may happen to be.
She is furnished with ten anchors, which,
with their stocks, weigh fhy.fye tons, and re-
quiro 800 fathoms of chain cable, weighing 98
tons, her capstan and waip weighing 90 tons
total, 2a3 tons Of applianceafOr making her fast.
sLLooSs AND CABINS,
She has ten saloons in all, five upper and five
lower. When a stranger first walks into st.
Peters church, at Rome, he feels a mOmentary
disappointment because IL ia not as largo az he
anticipated. Much OF this is Occasioned, no
doubt by the admirable proportion Of every.
| thlng-the statues paTticularyr-these being
generally 80 or 40 feet in height, and just about
as largo in proportion TO the sizo Of tho vast
nave as ordinary statues or living persons are
to ordinary churches. The spectator forgets
to compare the living people on the floor with
the vast expGnse Of some 400 feet overhead,
aud the immense space and area on every side.
But on the Great Eastern ship il is very dillet.
ents and ones IDEAS OF magnitude are more
than realized The rooms and cabins between
decks look like town halls the passages like
streets, and the whole like large town or city.
Thore Is no single saloon or cabin as large IN
proportion TO the size of the vessel as you see
on an ordinary ocean steamer. Ii would be bad
policy and a waste of space and money TO make
them 80. The epnncipal saloon ia finished and fur.

tions being both rich and ohsste; the oolors,
principally white and gold, enliVencd with rod
