The site of this embankment is happily chosen, is
some rie=d.thosgh the foundstkm- is not all that
could be At some distant ago a land slip
from the seithern side, of immense magnitude, has
nearly disked up the vale, leaving room for the
river burly discharge teelf through a narrow
gorge at the bottom. The length etas embankment
at its bass is therefore only 15 yards, whilst at the
top it spreads to a width of 180 yards. When the waters
of the little river Etherow shall have been backed
up and amminalated till the space indicated between
the two embankments is full, there will be a magnifi-
' cent lake varying from 20 to 90 feat deep, containing
180,000,000 cubic feet of water, and coming as area
of 130 sores of ground. Besides the waters of the
Etherow to fill this reservoir, however, and several
small streams Bowieg from ravines in the sides of the
vale, there is a considerable flow on the northern aide
of it from Hoyden Brook. This is near the
upper sad, and as the Hayden Brook come.
through a deep vale between the Cheshire
Hills, it has been neoreeery to throw a re-
siduum wall across it, like that across the
upper portico of the Etherow. At the upper end of
this reservoir, on the northern side, commences the
conduit which is to convey the water required to
Slasehaster. Oa the other side of this, as of all the
other reservoire, there is a conduit intended to carry
off the surplus and discoloured water, which may be
brought down the river in floods after heavy rains, so
that it may run to waste. The corporation will have
it in its power, therefore, by closing the sluice,,
to shut out the water of the streams
fading the reservoirs at all times when
necessary, both from the reservoirs themselves
and from the Manchester conduit, allowing the water
to back op against the residuum walla till it reaches
the waste conduit. To fully comprehend the difficul-
ties which the engineer has had to encounter it may
be isometry to state that there are numerous water
privileges along the Etherow, which have had to be
preserved. From a few miles further down the river,
all the way to Stockport, numerous cotton, paper,
print, and dye works have been established at differ-
ent periods, all dependent on the water of
the river for existence ; and the owners of these
have been naturally anxious to prevent such a diver-
sion of the stream as would be a hindrance to their
industry. They, however, under any except rue cir-
cumstances, require only a portion of the water in
the day, and that which now flows down during the
night runs to waste, and may be as well cooped up in
the reservoirs of the water-works as not. Their rights
and privileges have been of too much importance to
be left is doubt, notwithstanding, and the corpora-
tion having become by act of parliament the
conservators of all the waters of the vale of the
Etherow, are under compulsion to allow a certain
flow either from the natural sources of the river, or
from their reservoirs, to prevent the millowners sus-
taining damage. To facilitate this supply of water,
the river is allowed to flow through the reservoirs, to
the extent of its ordinary bulk, and is admitted and
discharged under the embankments, on raising the
eluizea, by means of two parallel cast-iron pi vs of 4
feet diameter each. A man in the service of the Cor-
poration will of course have to reside in the neigh-
bourhood to superintend and regulate these sluices.

The Torside reservoir is situate about a mile below
the one at Woodhead, and extends about a mile down
the river. The balk of the river is increased before
reaching this point by the accession of the waters
from Crowden Brook, Hollins Brook, and acme minor
s•reame. It is about a mile and three quarters in
length, varies from 18 to 100 feet in depth, and from
703 to 1,281 feet in width. The third reservoir is the
Rhodes Wood, commencing close to the Torside, and
its waters backing up against the embankment at the
bottom or the Turside reservoir. The Rhodes Wood
reservoir is about a mile in length, from MO to 1,074
feet wide, and from 1•i to 80 fe et deep. Although
this is the lest reservoir on the Etherow, the conduit
constructed to divert the surplus water to Manchester
is carried along the northern slope of the vale rearly
two miles further, where it reaches Tintwiitle. Here,
upon some rising ground on the north of the vale of
the Etherow, two streams, called the Armfield Brook
and the Holltogsworth Brook, fed chiefly by springs
up in the hills further to the north, nearly
converge, and the corporation are constructing two
other reservoirs in close proximity to each other to
intercept and receive their waters, instead of allowing
them to flow into the Etherow. The Armfleld reser-
voir, the largest of the two, covers sixteen acres, and
'they are consequently much smaller than the othere.l
It is unlike the others also in requiring a considerable
amount of excavation. The conduit to Manchester,
alter receiving its contributions here, flows on as be-
fore described, through a tunnel under the hills at
Mot•ram, to Godley and J /eaten, where the last of the
chain of reservoirs are situate. The entire capacity
of all these reservoirs, it is expected, will enable the
corporation to store in them six hundred million cubic
feet of water.

Of the whole tract of country from which the
drainage is to be cAlected for this scheme of water-
works, ab rat 1,500 acres is covered with decayed peat
moss, which, in heavy showers and floods is liable to
be charged with vegetable matter and other impu-
rities; and to avoid the mingling of such water with
the other, catch-water trenches will be run round the
sides of the hills to receive and carry it away to a
portion of the river where it will do no harm.
There will be some small auxiliary reservoirs to
construct, but these are not connected with the supply
of water to Manchester; they are intended to facili-
tate the supply to the mills along the Etherow, when
that stream shall be interrupted in its flow for pur-
ee connected with the reservoirs at Woodhead,
Torside, and Rhodes Wood.

Of course, with a daily sappy of 40 million gallons
of water the Manchester corporation will have a large
surplus after taking all that is necessary for their
own use, including the supply to trading establish-
ments as well as that' for domestic purposes; and
already arrangements have been entered into for the
sale of a considerable quantity to the corporation of
Salford. Some other towns near the line of works
will also, no doubt, make overtures from time to time
and be supplied from this source. To remunerate
them for the expense these works will put them to,
the corporation of Manchester are empowered to sup-
ply mains to all the houses in the borough, and lay a
rate upon the inhabitants.

SOCIETY FOR PROMOTING TUE AMENDMENT OF
Tan LAW.—Yesterday the annual meeting of the members
of this society was held at their oiliest', in liegent-street,
Mr. Sujetaat Manning in the chair. The report, which was
read by Mr. J. Steward, stated that the subject which had
principally engaged the attention of the society during the
present session had been the introduction of a more euy,
prompt, and effective mode of proceeding for the adminis-
tration of the estates of deceased persens, the establishment
of a law school, the publication of legal works, the report-
ing of law proceedings, and the printing of proceedings in
Saw and In equity, measures calculated to facilitate the
labours of the profession, and to increase its efficiency as the
agents and depositories of the law. The council expressed
their regret at the illness of Lord Cottenham, but congratu-
lated the society not onl on this promises it was making, but
on the means it possessed of realising those numerous demands
for reform with which there was so much general agreement,
and to which the society had been so largely instrumental
is attracting attention. The council also congratulated the
sheeting on the introduction of two measures—one by Lord
Brougham, alto other by Mr. T —for further reforms
Ia Cnaacsry. The council believed that the report of the
Real Property Commissioners would recommend the adop-
tion of a general registration of deeds, founded mainly on
the sane plan and principles as had already been suggested
by the society, and they concluded by stating that recent
events had fully justified the establishment of the society,
and that full attention was now given hy parliament to the
particular subjects which the society had planed before the
public. The report having been adopted, officers for the en-
suing year were appointed, and the muting/ broke up.

BILITISII AND FOREIGN SCHOOL SOClETY.—YrO-
terday the uwal annual elimination of the boys school of
this socimy, in the Borongh•road, took pines, Sir Kdwud
North Balton presiding. There was a large attendance of
visitors on the occasion, whxlipied great intanst in the
proceedings ; and it is not that they should do
so, for nothing could exceed t promptitude with which
answen were given to the various questions pat, or the ad.
wired, training and discipline evinced in the 00111111 of the
eausination.
