y Baltimore San special SAYS; The
general outlines of the plans for tho
new steamers being built by Cramp 81
sons Of Philadelphia, for the Inman
Company, have been determined upon,
getting ont material has commenced.
As has already been stated in the Sun,
there are to be six ships in ali. -Four of
the number are to be somewhat smaller
than the City Of New York and the
City of Paris, and are to run on the
line between New York and Antwerp.
Two are to be larger than the City of
Paris and the City Of New York, and
are to run with these vessels on the New
York and Southampton line, making
four steamers on each line.
The engines of these new vessel will
be their most interesting features, on ac-
count OF the great power they are to de-
yelop and the high speed they are to
give the ships. All the vessels will
have twin screws, with the engines in
separate water-tight compartments. The
smaller ships will have about 1900
horsepower and are expected to have
about the same speed as the City of
Paris and the City Of New York. The
larger ones are to have about $4,000
horsepower and are expected to be
faster than any vessels aaoat, including
the two new Cunarders now being built
on the Clyde. All the engines are to be
of the vertical, inverted, direct-acting,
neutrality-suspicious. type, with work.
ing pressure OF 80 pounds of steam to
the square inch at the boilers.
Their performance will be watched
with much interest for the reason that
this will be the first time there has been
any effort made to use quadruple-ex-
pansion in engines of over 4,000-norse
power, and in only one or two instances
has 1t been applied to engines of that
power. The advantage of quadruple-
expansion engines is i'll the saving Of
fuel, which will amount in these new
ships to about 10 per cent over Triple
expansion, and for the larger ships Will
be about 80 tons per day. Their coal
consumption is estimated at about 400
tons per day each. The difficulty III alb.
