The grade line of Aqucduct across the Harlem is o.
feet above tide water and the top Of the water now
passes Harlem river in pipe of Sc inches,
placed the Eastern dam made in the construction of
the high bridge.
| The bridge itself is about third completed,
and will be- when finished, of the most supendous
works Of the kind in the world.
The is GOO feet wide ut waler line, but the slope
Of the river banks add additional distance Of $50 feet

arches Of 80 feet span and piers of Is by "a feet a

two banks Of the river.
Tie sprnr of one of the arches is % feet above the

The interesting works at Clendening Valley being Il

height of the Aqueduct 30 feet from The bottom Of The
vuloy-heautru archways are constructed for three
Streets 81 feet for the carrasewcy and ten on each side
for size walks.
Next in interest is the Reservoir at Eighty sixth
street, which might we'll be called the OBTAINING
Clarifying Reservoir. II has two divisions, together
thiry-two acres-grea;est depth of water twenty FIVE
feet, containing one hundred and fifty millions Of gal
Ions Two lines of thirty six inch pipes connect this
with the Reservoir al Foreth street, which has also
two divisions forming together Of four acres

point four and half miles 10 the Battery. Whole

! The water in the aqueducL is regulated at the
trance gate, not 10 flow under any pressure-it
has not been permitted 10 flow in the division, the
city, at greater depth than two fee; but the works
at The Croton dam required, few days back, that
water should pass through the first division, he dis

eight miles, and it found 10 pass seventy five mil

lis velocity ever two miles per hour
The Croon lake retains, beyond the daily
river supply, in reserve five hundred millions Of gal
Ions and small expense would add other immense
artificial lakes TO hold back additional supply, but
the necessity of this is hardly conceivable. II is es
mated, that the London supply, from all their compa-
Mes but twenty four millions Of gallons, and Paris
four millions only.
The qnality of the water is of pure and transpa-
