ESTIMATED COOT OF THE WORKS.

Northern high level line, 6,66321. ; middle level gravitat-
ing line and branches (including land and relief for the
Fleet and Itanelagb), 220,1041. ; main low level line (in-
cluding ditto), 167,8501. ; extension of gravitating lines to
Barking Creek, &c., 167,6001. ; pumj log-engines, engine-
houses, pumps, &c., 68,0001. ; total, 690,0861. ; estimated
coat of sewers required to bring Acton, Iloddesden Green,
&c.. waters to Bayswater, 62,9951 ; grand total, 753,0411.
The report is signed " John Roe," and thus proposes to
effect a saving of 602,0001. per annum over the engineer's
plans.
Mr. Bazalgette reports upon Mr. Roe's scheme, which ho
states to be " unfit to accomplish that which is proposed,"
inasmuch as it is alleged ;that the data from which that
gentleman has worked is incorrect and the estimates imper-
fect. The proposed sewage littet Mr. Besalgette describes
as being " complicated and circuitous ;" the curves are said
to be of " short radii, retarding the flow of the sewage,"
and " calculated to create deposit in the sewers ;" such
curve., it being further said, having been " carefully
avoided by the engineers to the commission in their plan as
being serious objections to their efficiency."

♦BSTRACT OF THE JOINT REPORT OP SIR W. mini' AND

3111. B. lITZPILLNBON ON MN. ROWS SCURNII.

The report of Messrs. Cubitt and Stephenson as criers.°
occupied 30 pages of closely written manuscript. It will
be here sufficient, however, to state that ls,th gentlemen are
opposed to Mr. Roe's scheme, end that they distinctly ap-
prove of the intercepting spit, m with the following proviso:
—They say :
" In giving our recommendation in favour of an inter-
cepting system, we must be distinctly understood as coup-
ling with the approval of the system the condition that the
lines of sewers 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 are reduced in dimensions below those sug-
gested by your engineers, and approved of by us in our for-
mer 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 form •
correct judgment of the consequences that must inevitably
follow the adoption of dimensions incompetent to deal wit's
the ordinarily occurring heavy rain fells, and enable you to
appreciate clearly the advantages of a copious power of dis-
charge."
In closing their report the consulting engineers thus eon:
clu

beg to recapitulate the conclusions we have come
to, namely :
.1. That the design of interception proposed by your
engineer, engineer, Mr. Bssalgette, and Mr. Haywood, the engineer
of the City Commissioners of Sewers, is better calculated
t►an any other to effect the object.
2. That the dimensions they have fixed upon for their
sewers are not larger than are absolutely required to clear
the Thames generally, throughout the year of pollution.
" 3. That even with these dimensions, the Thames will,
occasiouslly, during very heavy storms, still be liable to have
discharged for -
