while the Lancashire portion of the subterranean work now extends to
St. George's Church, at the top of Lord street, on the one side, and
Merseyward to upward of 90 feet beyond the quay wall, and nearly to the
deepest part of the river.

When completed, the total length of the tunnel will be three miles one
furlong, the distance from wall to wall at each side of the Mersey being
about three-quarters of a mile. The underground terminus will be about
Church street and Waterloo place, in the immediate neighborhood of the
Central Station, and the tunnel will proceed from thence, in an almost
direct line, under Lord street and James street; while on the south side
of the river it will be constructed from a junction at Union street
between the London and Northwestern and Great Western Railways, under
Chamberlain street, Green lane, the Gas Works, Borough road, across the
Haymarket and Hamilton street, and Hamilton square.

Drainage headings, not of the same size of bore as the part of the
railway tunnel which will be in actual use, but indispensable as a means
of enabling the railway to be worked, will act as reservoirs into which
the water from the main tunnel will be drained and run off to both sides
of the Mersey, where gigantic pumps of great power and draught will
bring the accumulating water to the surface of the earth, from whence
it will be run off into the river. The excavations of these drainage
headings at the present time extend about one hundred yards beyond the
main tunnel works at each side of the river. The drainage shafts are
sunk to a depth of 180 feet, and are below the lowest point of the
tunnel, which is drained into them. Each drainage shaft is supplied
with two pumping sets, consisting of four pumps, viz., two of 20 in.
diameter, and two of 30 in. diameter. These pumps are capable of
discharging from the Liverpool shafts 6,100 gallons per minute, and from
