AN EXPERIMENTAL TUGBoAT.
The managers OF the same works nave now
nearly completed modern tugOoat, supplied
with boilers and machinery which they think
is destined TO create reyolution IN
power is supplied from binary engine, with Two
cylinders similar to 2 compound engine placed
in the upper or smaller cylinder (Which Is l3 by Is
nches), the same as is usual In high pressure en-
gnes; but the exhaust steam. ca m which Is commonly
containing bi-sulphide OF carbon, which evaporates
at temperature of liz degrees. This
cient to create pressure of sixty-nine pounds
in the second boiler and the steam Is
returned again to the original boiler. The vapor of
the bi-sulphide OF carbon is then applied to the
duces a power iuliy equal to that obtained in
the first instance. The engines work In

Of carbon cylinder Is condensed IN

that this boat Will be lully equal to high pressure
tugboat with cylinder Of 20x20 inches; also that
she will consume less than onehalf OF the fuel,

haust steam usually wasted in the open air. The

Prospects at Chester, Pa, and Whining
ton. Del.
WILMINGTON, DEL, Oct. 81, 1873.
The means of access to the ship yards OF Chester,
former is reached from Philadelphia by journey
OF iorty minutes, the latter by . ride of an hour
and hall. The two localities in no respects
the same, but on the contrary present very sur
prlsing contrasts At Chester you see particular
branch OF American industry pursued to the ex-
clusiOn OF every other. and at Wilmington you be-
hold this same branch in great deal smaller
magnitude, because mingled and confused by
hundred other various occupations. At one place
you view company of men, banded together
upon basis slightly cooperative, for the sole pur.
pose of building ships, ana nothing else. At the
other you behold q smaller body OF men engaged
not only In constructing ships, but also engines,
boilers water tanks, sugar mills cars, wheels and
| axes. The workmen at one locality reside near
| their work and have provided for them cosey and
! comfortable homes, while the wOrkmen at the
other are what are commonly denominated as
skilled, and live in various sections OF great and
prosperous city.
The shipyards of the Harlan and Hollingsworth
Company, OF this city, while being the oldest in the
United States are by no means so large those OF
the Delaware Ship Building Company at Chester,
Pa. At Chester the river has q greatar breadth
and depth than are indicated at this point, and
hence is better adapted for the launching OF great
vessels The Holngsworth Company employ 1000
men, and most of these have been identified with
the company for great many years. The
yards are exceedingly suggestive OF industry
and vitality, even IN this dreary season, when
the hand Of labor In so many quarters is forced to
lie at rest AS detailed description or the differ
ent Industrial processes involved in the construc-
tion OF a ship was given In former communication
it will be unnecessary to reproduce it here. The
mould lofts, boiler shops and joners' room at
/ Chester and Wilmington are very much the
same, while ribs are bent and sections formed
in both places by similar methods and machinery
The eye beholds before it the same pushing, tug
gng and hurrying everywhere, and the ear
Is greeted with the same rattng, Gathering sound.
| This company have been in existence for long
time. having been organized In 1S45, and during
the war constructed many vessels and gunboats
for the government. Among the latter can be
named the Sacaugus, Patapsco, which was sunk
at Charleston, ). c., and the Napa, now lying at
League Island, all Of which were Of the monitor
class and each OF which did very effective service.
Upon going down TO the shore the following vessels
were seen, either launched or on the stocks:-
THE GENERAL WHITNEY,
fine iron steamer for the Metropolitan Steam
ship Company 225 feet long, 40 feet beam, with q
capacity Of 1000 tons vessel calculated to make
very fast time, double decked, and exceedingly
well appointed. Next very large propeller Tor
the Baltimore Steam Propeller Company, named
Seaboard, which is IT'S feet long, 2S feet beam and
IL feet deep Next again, an immense IRON steamer
tor freight and passenger conveyance, named John
Hopkins built Tor the Merchants and Miners line,
which plies between Baltimore and Boston. The
ship is 240 feet long, 3S feet beam and 20
feet Deep having three distinct decks

and examined all her various apartments. The
machinery was wrought up in the most elaborate
way, and, ike oil pieces OF practical mechanism,
was graceful and symmetrical. The decks were
broad and slightly curved, while internally and ex-
