CAN.II. NAVIGATION.

Oa 'Wednesday last an experiment was. made on
the brand' Junttion Canal, near to Berkbampstead,
in Hertfordshire, for ascertaining the loss of time
which would be oecasionedby reservoirs being used
adjoining to the lock of a canal, for sat:ittg a pot.
ton of the
.water which would other w be let down
out of the higher leyet, or pond, ofa Canal into the
lower, on the passing of ev,ely barge, either upWards
Or downwards. The resort of this experiment was,
that onehalf of the water requisite to fill a lock may
be reserved eaela tirue with the lott of three Inintnes
and a half only in tame ; a 3 the barges which -arc
usually file and iltalt- minutes its pat,,ing,-took up
only about nine minutes %Oa n this saving of water
was made.. On this occ.asion, two side pounds, or
reservoirs, were, constructed, etch of the_ same
perficial area as the IOCk of the 'Canal which they
are near, and wherewith they conned by means of
sluices, which pen the water as qhf as possible,
either into or out of the lock.. The first of these
side pounds has itsbottom something less than half,
and its top-snmzwhat more than three-fourths, of the
height or depth,of the ltick, -and c its.equently, on
opening. its sluice as aD. came-down' one Or.
ter of the water of . the Lick flowed into it wise') its
sluice was agiin silty; the sluice of the second side
pound was there opened, and into this (As bottom
not beirlg above half the height of the lock) about
;mother fourtb part of the water;Of the lOck flawed,
and was retainesl there by the shutting of the sluice;
the remaining half of the water in the lock was then
let down into the lower pound as usual: A Barge
which was going up then entered the lock, and, the
doors being shut, the sluices oldie side 'pounds were
Opened; and one half of the height `of the lock was
tilled by the water tliereitt reserved from the pdssage.
d the-former barge; the remaining half. of the
lock was in the usual way -iron ale tipper
pound, and thus only one lock full of water was
consumed, t,r let down, by the passage of one
ha-rge dOwn and another up the canal', the lock
also ieMain:rig full for " the passage of the.next
barge downwards. these Side pounds 'possess the
adVantage of being- used or not, according as a
dry or wet season may make a saving of water
rkeessary or nor for ihe canal ; and seem in offer a
better eXpecljent than. the One hitheito adopted, of
rivitiv,r auras, that is, in a dry tittle, no barge
s-hould pas a lode upwards 'tilt another barge, is
arrived and ready to pasi down with the same
lock 101 l of water; for the locks ate not allowed to
stand full of water, on account of the extra leakage,
antfrif danger to the walls of the kick. • Two boats
heavily laden with flints from thechalk-Ots, intend.
eel for the potteries -in Staffordshire, were the first
which passed upwards using the side pounds.—
These side pounds may, it seems, be construtied in
the space of-a. week Or two, and will probably co:t
about sixty pounds at each lock, of the usual thatell.
sioos.. From the above, it iS'prOb:ible that several
Of these side pounds:to the hicks wiii be committed
upon the Grand jundion Canal.
