DESCRIPTION OF THE CITY OF NEW YORK.
servoir, in Eighty-Sixth street, is by the cars of the Harlem
Rail Road, which leave the Depot, at the junction of Chatham
and Centre streets, opposite the City Hall, every fifteen minutes
during the day.
Estimated Cost.—It was at first estimated that it would cost
ixve or six millions of dollars; and at the city charter election
of 1835, the citizens were required to vote for or against supplying the city in this way. The whole number of votes given was
17*330, of which 5,963 were against it, and 11,367 in favor of it.
Cost of the Work.—The whole cost of the work will be about
$14,000,000. There are laid between the Distributing Reservoir in Fortieth street, and the Battery, 150 miles and 3,665 feet
of pipe, from 6 to 36 inches in diameter, the majority of which
is from 6 to 12 inches in diameter; and free hydrants are
opened in most of the streets, besides the fire hydrants. There
are 1400 fire, and 600 free hydrants.
Extent of the Supply of Water.—The minimum flow of
water in the river, where the dam is constructed, is considered
to be twenty-seven millions of gallons for every twenty-four
hours, which would be a sufficient supply for one million of
inhabitants. It is considered that the supply for the present is
abundant, even during a season of drought, for one million
and a half of inhabitants, nearly five times the present population ; and streams can be found which can be turned into the
upper branches ofthe Croton, if the time ever arrives when the
population of the city will require an increased supply.
Velocity of the Water.—The velocity of the water in the
aqueduct has been ascertained to be about one mile and a half
an hour where it is two feet deep.
\ The Dam—Is 250 feet long, 70 feet wide at bottom, and 7
I feet at top, and 40 feet high, built of stone and cement. It
creates a pond Hve miles long, covering a surface of 400 acres,
and contains 500,000,000 gallons of water.
The Aqueduct proceeds from the dam, sometimes tunnelling
through solid rocks, crossing valleys by embankments, and
brooks by culverts, until it reaches Harlem River, a distance of
thirty-three miles. It is built of stone, brick and cement, arched
over and under, six feet three inches wide at bottom, seven feet
eight inches at the top of the side-walls, and eight feet five
inches high, has a descent of thirteen and a quarter inches per
mile, and will discharge sixty millions of gallons in twenty-
four hours.
