IA REMARKABLE TUNNEL,
WILL RUN UNDER THE EAST RIVEP
AND MANHATTAN ISLAND.

Work on This Gigantic S1O,OO0,OOO On.
dertaking In Greater New York to
Begin This Winter-Will Ultimately
Connect Brooklyn With Jersey City.
The most remarkable tunnel on the
Continent, which will cost $40, 900, 900,
is to begun this winter by the Jersey
City, New York and Brooklyn Tunnel
Company.
According to the officers of tho com.
pany it ultimately connect Brook yn
with Jersey City, but for the present
It's western terminus will be at the
North River, and it will extend easter.
~ for three miles under Manhattan
Island and the East River, coming to
the surface at the Long Island Rail-
road Flatbush avenue station.
The tunnel is expected to solve the
problem Of rapid transit between the
boroughs of Manhattan and Kings.
At the easterly end the tunnel will
be carried under the Brooklyn streets
in horseshoe shaped arch of ma
sonry, measuring Is feet in width and
is! in heighth, Where the top Of the
tunnel is near the surface the street
will be supported on iron girders, with
brick arches between them.
From the beginning to the lower
level there will be light grade, which
will carry the bottom of the tunnel
100 feet below the surface of the
ground when it reaches johnson
street, where there will be q station, !
connected with the street by per-
pendicular shaft, in which will be
operated elevators.
When the tunnel reaches the East
River its character will be radically
changed, for from a single arched way
It will be divided into two parallel cir
sular iron pipes, each 149 feet in d.
ameter. These pipes will be formed
Of cast iron sections, firmly bolted to-
yether. They will be carried in a di.
'ect line below the river, 80 feet under
It's bottom and 80 feet below low tide
Of the water, and strike the westerly
shore OF the end of Maiden Lane.
Here the tunnel will not resume the
form used in Brooklyn, but the iron
pipes will be continued under Maiden
Lane and Cortlandt street, at dis
tanoe of about hundred feet from
The surface, until the North River is
reached.
The depth Of the tunnel brings it so
Tar below all sewer supply pipes and
building foundations that it cannot
interfere with or be effected by them.
Then the nature Of the ground, as
shown by borings along the route-it
being lime rock and shale, with occa-
,ional beds Of gravel-offers no en-
cheering difficulties, not even so
ouch as those which the English en-.
bineers encountered and easily over
same in the construction Of the net
work Of underground railways in
London, which run in tunnels Of
larger diameter than any others in the
world.
This New York tunnel will be built
Che same as the London ones. It will !
pc perfectly dry, and ventilation will
be ample, as the entire air will be
changed about every five minutes, not
only by the movement Of frequent
trains, but also by the means Of air
shafts.
Besides the terminal and johnson
street stations in Brooklyn, there will
be two stations in New York, conven-
ent to the elevated railways and co.,
1ected with the surface BY elevators
'unning in shafts about q hundred feet
ong. .. -.
About two years. time will be re-.
luired to complete the work, for thd !
builders are anxious to get the road /
nto operation, and will ALLOW no de,
