PROPOSED NEW LINES OF SEWAG/1.

Mr. Roe proposes a new line, to be called the
"Northern high level" or "Hackney-brook line." In
this instance it is intended to " provide for the whole
of the surface drainage as well as for the sewage."
He suggests that this line " should commence at the
entrance to Tufnel-park, or Upper Holloway, with
• a sewer 5 feet by 5 feet diameter, and passing
thence to and along the fields to Highbury-vale and
Stoke Newington." This line he denominates the
" Middle level line" is suggested to commence opposite
the church in High-street, Kensington ; thence con-
tinued to and along Hyde park, where it will relieve
the foul drainage coming from the Bayswater and
Acton sewer ; thence its course is along Piccadilly, re-
ceiving, by connecting junctions, the sewage from the
Icing's Scholars' Pond and Regent-street sewers ; thence
by St. James's-square, Orange-street, the Strand, Fet-
ter-lane to Holborn ; thence by West-street, Smithfield,
Chiswell street, and Finsbury square to Curtain-road,
where it would receive the Old-street-road branch.
Its course is then along Church-street to Bethnal-
green, thence under the Regent's-canal to near
the Lea, where it would receive the sewage
from the Old-Ford and Rosemary-lane branch,
and a little further the sewage from the Hackney-brook
line; then passing under the Lea and other streams
to the outlet at Barking-creek. The " Old-street
branch lice" he proposes " should commence at the
river Fleet sewer near- the House of Correction, Cold-
bath-fields, passing by Wilmington-square, St. John-
street, Old-street, to the junction with the main line in
Curtain-road." The "Old-Ford and Rosemary-lane
branch" is suggested to "commence in Water-lane, Fleet-
street, and to pass along Cannon-street, Rosemary-
lane, New-road, Back-road, White-horse-street, to the
World's-end, Stepney ; thence across Mile-end-road and
under the Regent's-canal above the lock, near Mile-end-
road bridge; thence by Bearbinder-lane to its junction
with the main line." He further suggests that the "Low
level line should commence near to Chelsea Hospital, to
the Victoria-street sewer, along Whitehall, Charing-cross,
the Strand, New Bridge.street ; thence to and along Can-
non-street, Eastcheap, &c., to the Commercial-road; then
parallel with the Limehouse-cut, to and under the Lea and
the West Ham Railway, a little beyond which the
pumping station is proposed to be formed. The sewer
into which the water is to be raised has its course in
nearly a direct line to where it will meet the grdvitating
line near the Barking-road, and then runs parallel there-
with to the proposed reservoir." He states that "
acres would drain into this line, if the Isle of Do'd§'
drained into it, but of these many acres might be re-
versed to the gravitating line." He proposes that " the
pumping station on the low level sewer should be 32
feet below the sewer proposed to convey the water
to the reservoir, with engines of about 450-horse
power.", The reservoir to be "GO feet in width, the
waters to be delivered at the turn of the tide. Storing
capacity of reservoir to ba 7,000,000 cubic feet of water."

ESTIMATED COST OF THE WORKS.
Northern high level line, 66,6321. ; middle level gra-
vitating line and branches (including land and relief for
the Fleet and Ranclagh) 220,104/. ; main low level line
(including ditto) 167,8501. ; extension of gravitating
lines of Barking-creek,.&c., 167,5001. ; pumping-engines,
engine-house, pumps, &c., 68,0001. ; total, 690,0861. ;
estimated cost of sewers required to bring Acton, Hod-
desden-green, ece., waters of Bayswater, 62,995/. ; grand
total, 753,681/. . .

The report is signed " John Roe," and thus proposes
to effect a saving of 502,000/. per annum over tho engi-
neer's plans.

Mr. Bazalgette reports upon Mr. Roe's scheme, which
he states to be "unfit to accomplish that which is pro-
posed," inasmuch as it is alleged
.that the data from
which that gentleman has worked 18 incarrect and the
estimates imperfect. The proposed sewage lines Mr.
Bazalgette describes as being " complicated and circui-
tous ; ' the curves are said to be of "short radii, re-
tarding the flow of the sewage," and " calculated to
create deposit in the sewers ;" such curves, it being
further said, having been " carefully avoided by the en-
gineers to the commission " in their plan " " as being
serious objections to their efficiency."
ABSTRACT OF THE JOINT REPORT OF SIR W. CIIBITT
AND MR. R. STEPHENSON ON MR. ROE'S SCHEME.

The report of Messrs. Cubitt and Stephenson in ex-
tens° 'occupies 30 pages of closely-written manuscript.
It will be hero sufficient, however, to state that both
gentlemen are opposed to Mr. Roe's scheme, and that
they distinctly approve of the intercepting system with
the following proviso :—They say—
"ln giving our recommendation in favour of an inter-
cepting system, we must be distinctly understood as coup-
hng with the approval of the system the condition that the
limos of seweis which have to perform the duties now so
imperfectly performed by the Thames must not be stinted'
in their dimensions with the view of saving money for the
moment, as we- are thoroughly convinced that if, with
this view, they aro reduced in dimensions below those
suggested by your engineers, and approved of by us in
our former reports, nothing but disappointment awaits
you and the public. We have, we trust, • put the
question before you (the commissioners) in such a manner
that you may forma correct judgment of 'the conse-
quences that must inevitably follow the adoption of
dimensions incompetent to deal with the ordinarily oc-
