That Wilmington workmanship Is of
the highest class and commands the
attention of capitalists in the largest
cities is fully demonstrated by two.

the handsome new steamer. Richard
Peck, has done, appearing in the Ameri-

Great Success OF the Twin screw.
1T is only recently that the screw has
begun 10 replace the sidewheel In the
passenger service on Long Island sound.
How we'll the twin screw is adapted to
the requirements + that service, in the
speed attained and ease Of manipulation
in the crowded waters Of the East river,
Is demonstrated by the success OF the
Richard Peck. of the New Haven Line,
which created quite a sensation at the
time Of its addition to the feet two years
ago, and which In confined service has
fully demonstrated the advantages of
the type Of which IL il an example. Her
length on the water line is 800 feet, over
all 3l6 feet, beam As feet, breadth over
guards GO feet, depth of hold, 1874 feet.
ut is In the motive power that our
readers will be chiefly interested. This
is furnished by two triple expansion
engines, having "a 80 and 6O-inch
cylinders, and 30 inch stroke. run
regularly at 1870 revolutions per minute,
or $50 feet Of piston speed, and develop
ing with an initial pressure of 100
pounds about 4 $50 indicated horse
power. Each engine is connected to its
own screw, and works entirely inde-
pendent Of the other.
THE valves are controlled by ordinary
marine link motions operated by means
OF steam ram, single stroke OF which
shifts the blocks through the entire
length Of the links. The steam rams
are operator by the small levers shown
in the centre of both engines, and so
easily are they manipulated that one
man standing between the engines can
operate both. Piston valves 10 inches in
dismeter are used on the high pressure
cylinders, and slide valves on the in.
termediste and low, those on the low
pressure being double ported. The
valves weigh as follows: High pressure,
200 pounds; intermediate, 700; low pres
sure, about 1000 pounds
Each engine has its own surface con-
denser of the type ordinarily furnished
BY the builders of the huli aud machin
cry, the Harlan & HolliDgsworth Co OF
Wilmington, Del. These are parallel
with the engines and behind them. The
circulating water is supplied by centrif.
ugsl pumps, one for each engine,
operated by small vertical engines
directly connected to the pump shafts.
Should an accident occur to the crcula.
ting apparatus or the surface condenser,
jet may be used, and an escape valve
is provided for autom atioally discharg
ing the exhaust to the atmosphere In
case of the total disabling of the con.
denser. The air pumps are vertical
single acting. operated by beams
receiving their motion from the lower
pressure crossheads
