Consilerable discussion arose as to whether Mr. Les-
lie's motion. on ;the !main intercepting sewage, and the
seven resolutions that had been upon the agenda paper
for several days, be printed and circulated amongst the
members of the board, and they!be discussed on Tuesday
next.

This motion was put and lost on a show of hands ;
upon which Mr. Leslie demanded a division, when the
numbers were—for the motion, 5; against it, 21.

THE SOUTHERN MAIN DRAINAGE.

Mr. BAZALGETTE, the engineer, presented the follow.
ing further report upon the main intercepting sewage of
the south side of the Thames,' in conformity with the
views of the Government :

" Gentlemen,—l have now the honour to present the
plan, section, and estimate for the extension of the main
outfall sewer on the south side of the Thames to Long
Reach, as directed by the foregoing resolution.
" I recommend the construction of a sewer 10 ft. 0 in.
in diameter, 7i miles in length, and with a fall of 2 ft.
per mile, commencing in the Piumstead-road, at the
east end of Woolwich Arsenal, where it forms a junc-
tion with the main outfall sewer, which was adopted by
the board on the 26th of May last. The extension line
,neakinuaitthence alodg tbe north -bide 'of the linteliM"
Railway, through Erith, under the river Darent, to the
Thames at Little Powder Creek, which is about the
centre of Long Reach, one mile below Purfleet; two
miles above Greenhithe, and 19 miles below London-
bridge.

"This sewer would be substituted for the last mile
and a half of the outfall sewer, across Plumstead-marshes,
which will, therefore, have to be deducted, leaving a net
increased length of about six miles. The invert of the
, sewer at the point of discharge in Long Reach will be
32 feet below mean high water, requiring pumping
power in addition to that already provided in my esti-
mate of the 3d of April equal to 328 nominal horse
power, and the cost of duplicate engines will here be
provided for, as in the original estimates. It will, how-
ever, be unnecessary to provide these duplicates until
the anticipated improved water supply and increased
population shall have been realised, which will not be
the case for many years to come.
"I recommend that for eleven months in the year the
discharge of the sewage into the river should take place
at high water, and during the first half of the ebb-tide ;
and that for the remaining 20 or 30 days of heavy rain
the discharge of the diluted sewage should also take
place one or two hours before high water, by which
means a reductiou of the size of the covered reservoir
from fifteen to four acres might be effected, and an in-
crease of its depth obtained, so that it would contain
about two millions and a half cubic feet. In other words,
it would not be more than half during nine months in
the year, and would leave the other half of the reservoir
free from the storeage of upwards of a million of cubic
feet of rain during the remaining three months. This
will be found sufficient, probably, fer the next 15 or 20
years, and it would be better hereafter, if necessary, to
enlarge the reservoir, rather than now to spread its con-
tents over a more extended surface. The foregoing in-
structions, however, direct the preparation of a plan for
the discharge of the sewage at and after high water only.
I therefore beg to report, so sudden and unequal are the
quantities of rain that fall, that to avoid the discharge of
the sewage before high water on the 20 or 30 wet days per
annum would necessitate the construction of a reservoir
of double the size now proposed, at an increased esti-
mated cost of about 40,0001.
"It appears from the late Mr. Foster's tidal experi-
ments that a float started at the proposed outfall at
Long Reach, at half-ebb, would ascend with the follow-
ing tide to about 52 miles about the starting point, or
to Halfway Reach, and that discharged two hours before
high water would ascend only four miles above the
starting point, or to Frith Reach, the latter being the
most favourable ; but in neither case would any of the
sewage so discharged again return within the limits of
the metropolis. I therefore recommend the construc-
tion of the smaller reservoir.

It was resolved that this report be printed and circu-

up for discussion on Tuesday nest

NEW STREET EROM OHEAPSIDE TO THE WEST-END.

Mr. LESLIE brought forward a resolution, of which he
had given notice, calling the attention of the board to
the desirability of combining in one or two acts of Par-
liament the following metropolitan improvements :
An entirely new line of street from the west end of
Cheapside, having a viaduct across Farringdon-street,
with a continuation through the proposed improve-
ments in Carey-street, with a continuation from thence
to the proposed improvements to which his Grace the
Duke of Bedford has agreed to contribute 15,000/. ;
the whole length of such new street from St. Mar-
tin'e-lane to the west end of Cheapside would be
about one mile and 1722 feet, equal to 7002 feet lineal.
Mr. Leslie said he thought that no one would doubt the
necessity of a new thoroughfare to relieve the traffic be-
tween the City and the west end, from the west end of
Cheapside. He thought it was equally certain that any
attempt to improve Holborn-hill would not meet the
wants telt by the metropolis in this respect—what he
desired was that they should have a continuous line, ex-
tending from the west end of Cheapside to the southern
side of Newgate, crossing Farringdon-street by means of
a viaduct through,Carey-strert, joining Hart-street, and
connecting itself with the new thoroughfare proposed by
the Duke of Bedford, to go into St. Martin's-lane, run-
ning into Cranbourne-street, Leicester-square, and into
New Coventry-street. There were several plans on the
subject—one by Mr. Tito, another by Mr. Bennoch, and
another by Mr.Mosely. There was also another plan,
of which there was a beautiful model in the possession
of the Corporation of London, which he had desired
should be brought before the board, but Mr. Hall had
objected, saying they had a plan of their own. He re-
gretted it, because he thought it would have afforded
valuable information to that board. Mr. Leslie con-
cluded by moving his resolution.
There being no seconder the motion fell to the ground.

THE NORTHERN MAIN DRAINAGE.
Mr. CoLLINSON moved that the resolution of the board
of Juno 17 (No. 7), to the effect " That the report of the
engineer, so far as it relates to the extension to Barking-
creek, be adopted," be rescinded ; and that, in lien there-
of, the engineer be instructed to prepare plans and esti-
mates for an extension of the northern drainage outletl
to some, point beyond the limits of the metropolis, near
to Long Reach.

Mr. COLLINSON said he had brought forward this mo-
tion in order that the board should act with consistency,
for it was quite certain that if the Government objected
to Pluinstead; on the south side of the Thames, for the
outfall of the sewage, they would equally object to
Barking-creek, on the north side of the river. For his
own part, he could not see the necessity of their being
compelled to go so far as Long Reach on the south aide,
but it having been carried, he thought it' would only be
a delay of the sewage question if they did not determine
on altering the site of the ,present northern outfall, as
the Government would be sure to reject it.
Mr. SAVAGE seconded this motion.
Mr. WRIGHT opposed the motion on the ground that
any alteration would be calculated to rescind and upset
the whole of the bases upon which the northern great in-
tercepting sewage had been settled by their engineer.
Mr. BAEALGETTE, in answer to questions put by Mr.
Wright, said it would to a certain extent set aside his plan
for the northern main sewage. It might, in consequence
of such alteration, be necessary and desirable to connect
the southern main sewage with that of the northern side.
Mr. WRIGHT moved as an amendment that this ques-
tion be deferred until after the board had discussed the
question of the general outfall.
Major LYON seconded the amendment ; and
Mr. Howe and some other members having spoken, .
The amendment Was declared to be carried. On a
division the numbers were—for the amendment, 15 ;
against it, 12.
