THE CROToN AQUEDUCT.-This magniti-
cent undertaking, for the supply of New
York city with water, is now completed.
with the exception of the construction of
bridge across Ilarlaem river. The estimated
cost of the whole work i twelve millions of
dollars. 1t Is about four years since It's com
menccment, and during that time, four hun
dred men have been constantly employed,
whenever the season permitted. The water
Is taken Gom Croton river, at a point distant
about forty miles from the City Hall in New
York. \ dam is constructed across the
river. which retains the water IN a grand
reservoir. The New York Tribune de-
scribcs the dam a a mound of earth and
masonry, 10 feet higb, and ID feet wide at
the bottom, and has connected with it many
complicated but perfect contriyanccs. to cna-
bic the engineers TO have complete control
over the mighty map Of W ,ter. The river.
thus thrown back towards lis source, forms
lake of 80 acres, which will retain a supply
of water for emcrgcnccs, of some thousand
millions of gallons, and also offer, a, a col
lateral advantage, many picturesque sites tor
country seats upon the woody points which
in. out into smooth basin. \ tunnel leads
the water from tais reservoir into the a1ue-
duct. and eleven more of these subtcrranc-
Gus passages, occur before reaching IIarla-
en- river having an aggregate length of
a mile. and many of them being cut through
the solid rock. At intervals OF "A mile ven
tilators are constructed, in the form of tow
crs OF white marble, which give to the water
tue exposure to the atmosphere without
which 1t becomes vapid and inSipid; and
these dazzling turrcts mark out the lin OF
Il. 4. a. ftlF
Hudson. The main water channel Of thc
aqucduct is said TO consist of an INN ensc
mass of masonry. six feet and Il half wide
nine feet high, and forty miles long, formed
of walls three feet thick, ccmcntcd into solid
rock.
There are several reservoirs on the linC
OF Che aqucduct. The receiving reservoir. a
iorkyilIc, i divided into two parts, boz
covering 4 space of thirty-livc acres. Il "il
hold 100 millions of gallons. 1t Is cncio,cC
by immense granite walls of masonry. Tho
natural soil forms the bottom of this huge
basin. There i another res oryoir al Sol
street. about five miles from the City Hall
occupying between - and 20 acres, whic!
f supplies three distributing piPes-onc o
them for Yorl,yilc. and the o.hcr TWO 70

reservoirs of immense structure.
