Evening journal., 1917-10-29

short business trip, including a visit
10 New York City, and the children
we're, therefore, anxiously awaiting his
arrival.
Il wonder what he'll tell us about
tonight?" asked Joe.
He always has something special TO
tell us after he's been to New York"
said Helen. That's such big, big
city that there IS always something
new and wonderful happening there"
And Jimmy and Joe and Helen were
not to be disappointed. for ten minutes
later, when Uncle Harry had arrived
and greeted everyone and was seated
In his favorite chair. he began:
We'll folks, while ! was away heard
sll about the greatest thing Of IT'S kind
that the world has ever known. Would
~ou like 70 hear about IT,"
A chorus OF "yes, yes, tell usr' was
hs ready answer from his fellow mem
brrs, and Uncle Harry continued:
There has Just been completed I'm the
&c Of New York the largest, and IN
" way the greatest, water supply
IN that has ever been constructed
where on this earth. Through this
I'm billions and billions Of gallons
vater-1ne clear mountain water,
carried i20 miles. 90 the millions OF
le in New York City
guess they turn on the spigot and
let the water run through a pipe all
the way from the mountains right
down to New York City, don't they?"
said Jimmy. winking at Helen.
bO0,0OO,O00 Gallons Every Day.
Uncle Harry smiled as he said: "Jim-
nnae NhnNfa 90 4
that pipe that you speak Of is the
biggest pipe that was ever made. Have
you any idea how much water flows
through that pipe every day."
"A good many gallons" answered
Jimmy.
At which 10 was Uncle Harry's turn
60 laugh. as he said: Every twenty
four hours there flow through that
'pipe'-as Jimmy calls It, 500,OOOOO0
gallons Of water, which Is the quantity
Of this liquid" and Uncle Harry held
UP a glass Of water that happened TO
b. on the table. 'sused by the more
than 100000 people in New York City
every day.
But I want TO explain TO you about
Jimmy's pipe The correct name for
such pipe is 'aqueduct' and the name
OF this. the worlds greatest water sup
ply system Is the Catskill Aqueduct."
Il know why they call it that" said
Helen quickly. 'Aque' comes from the
Latin word aqua which means water
and duct means 70 lead. Isn't that
right Uncle Harry7"
That's absolutely correct" said I'm
Gle Harry. And now let mo tell you
about aQueducts in general and this
newest and greatest one In particular
people have been building aqueducts
and for the very same purpose q
supply cities with water-for more thar
5000 years. One Of the most histori,
aqueducts supplied water TO the an
cient city OF Rome. But this new Cats
Kill Aqueduct is especially notable be
cause OF the wonderful engineering
work that had 10 be done in construct
ing IT, next 10 the building Of the Pa
mama Canal 10 Is considered the great
est piece Of engineering work In thI
world"
Under Mountains and Rivers.
1T must have taken a long while T.
build H." said Joe.
TT did," answered Uncle Harry. "Ac
tual work was started twelve year
ago. and Just a few days ago, While
was in New York, the entire system
complete in every way, was turneI
over 90 the city government, and I
now in fun operation. Now let me tel
you a few Of the things that make thi
aqucduct such great engineering
work. In the first place, II is i20 mile
long. More than half OF this length I
constructed Of concrete-enOugh con
crete to make a sidewalk two yard
vile and four inches thick, from Ney
w X City 10 san Francisco. This por
{ is shaped like a horseshoe and
feet high and ~ 10 feet wide, whlc
lkcs 70 large enough for the operatio
q single track railroad OF standar
size cars. A little less than half Of Tn
i2O miles is in the form OF a TUNE
about - feet in diameter, cut throug
solid rock. A part Of this tunnel run
under the Hudson River, about 100
feet below the bottom OF the river. Al
other part runs the entire length {
Manhattan Island, a distance OF
miles. through solid rock. making
the longest continuous tunnel I'm N
worldi More than 100000 pounds
dynamite were exploded in blasting IL
way for the tunnel under New IoT
City. hundreds OF feet below the street
The great high buildings and the sui
way trains"
you said II was mountain water IN
is being supplied TO the people OF Ne
York. but YOU didn't tell us how u
water is collected" said Jimmy.
How tho Water Is Collected.
clad you spoke OF that" answer
Uncle Harry, because that is especial
interesting and the work done in bull
ing that part OF the system is partic
larly important. What was done W
simply this; great concrete dams we
built. forming artificial lakes, in
which flows the water from q
streams all about these sections Of q
raiskll Mountains-the hills formi
lhe sides OF the lakes and the dan
