4 NEW ATLANTIC STEAM COMPANY.

We take the following interesting description Of
some intended monster ocean steamers from Htehs
eVs Steam Slipping Journal.

the big ship have the experience Of Brunei and Rus
cell as their guide. The new steamers will be 600
feet IN 9Th, 80 feet BREADTH and 80 feet IN depth
from the upper deck to the keelson. On the spar
deck viii be a grand saioon under the hurricane
deck 500 feet In length, with l64 state rooms enter

tions rpringing from side kelsons. The breadth of
the saloon will be % feet aud hight 10 feet inches.
The draught of water will be II to Is feet 60 that
from the load line to the top Of the hurricane deck
will be ~ feet inches. From the water level to the
upper deck will be II feet and then feet buwarks.
The ships will be built 10 three watertight
longitudinal bulkheads from bow to stern,
which will give them enormous strength.
THIS structure converts the ships below the load
line to perfect tubular divisions, taking the form
Of three distinct ships. In addition to the fore and
aft bukbeads the intercepting cross partitions VIII
afford additional security and give altogether nifty
water-ght compartments, SO that the vessel will be
nearly unsinkable. The two eide longitudinal par
ttions are Is feet apart and thus as the ships are
IS feet beam they make three equal divisions OF %

chinery il the steering gear were carried away, and
they would never require sails to bring them up TO
the wind, therefore masts and yards may be dis
pensed with, and so lessen the tendency 10 rolling

be provided, but the ships are to be steered by
combination of steam snd water cylinders. As sn
extra precaution eide fins rudders will be fixed,

speed. IL is intended to give them large engine
power, not necessarily 70 work always at high
pressure bet to supply an abundance OF steam.
The nominal horse power OF the engines will equal
the Great Easterns although the ships will not DO
more than half her tunnage. Ii is estimated that
their total displacement will be rather over 5000
tuns, and that the midsbips, or greatest secuon
of displacement, will be near upon 200 square
feet. When loaded, they will draw eighteen feet,
or nine feet less than the Great Eastern and Alto
gether their depth of hold will be % feet lees. From
