from Rochester IN. " Democrat, February o.
AT THE GREAT PARIS EXPOSITION
OF 1857 display OF an apparatus for throw
ing water for fire and other purposes was
made, the result of which was deemed ex-
traordinary, and it was flashed by telegraph
all over the civilized world. What was it ?
Simply that two-inch stream had been
thrown to height of $50 feet. Nothing of
the kind had ever been done before, but it
will be seen from the official figures given
below that height of 297 feet was attained
yesterday by stream of double the diane.
ter. Though subjected.to the seYerest tests
yesterday in order to bring about such re.
suits, the machinery Of the Holly works, in
its every part, was found equal to every re-
quirement, and there is every reason to be.
leve that it is the best Of its kind ever put
up. 1t is considered by men Of the greatest
experience that the display Of yesterday
transcribed in every particular all others of
the Holly, or any other system thut have
ever taken place, either in'this country or in
Europe.
After telling of various experiments, the
Democrat says:
An opening had been left in the street,
which when not In use is covered with
tight-ftting iron plate. BY means of this
opening pipe Of peculiar shape was fas-
tened to the main in the bed below. This
pipe was fitted with mouth-pieces of differ
ent sizes, and its position or angle Of execu.
ton could be altered at pleasure. The first
exhibition given with this apparatus was the
FoUR.INCH HORIZONTAL STREAM.
If the exhibitions previously given were
such rs to call forth praise and admiration,
the one given by this stream was, in truth,
| most astonishing. After it had been playing
only q few minutes every one thought it
| was doing splendid work. They thought,
however, it had reached the full extent OF
| its power, and the crowd began to close up
| to il. OF this they soon after repented, as
| with spring the water shot suddenly for.
| ward and continued to increase its distance
until the astonishing sight was presented
| of four-inch stream issuing from pipe,
| arching gracefully in the air, and striking the
| ground ut a distance Of 460 feet from the
| point of starting.
THE THREE-IscH VERTICAL STREAM.
The horizontal stream was shut off and
| the deivery.ppe raised to a vertical posi-
ton. The water was then Immediately lei
on, and the stream crept gradually up unit
the great height Of go feet was reached.
THE rouR-INCH VERTICAL STREAM.
Cutting Off the three-inch stream, th'
mouth-piece was removed, and another one
adapted for four-inch delivery fastened il
its place. Soon another fine stream, fou
inches in diameter, was seen mounting il
the air. This stream reached the eXtraerdi
nary height of 297 feet. Afterit had played
its allotted time the water was shut of, the
nozzle changed, and ia few minutes tin,
great
FIvEINCH VERTICAL STREAM
was In operation. It would seem hardly
credible that a stream of water five inches in
diameter could be forced by any system o.
machinery to beight far above the one-iuct
streams thrown by ire-engines. Neyerthe.
less. such was the case, IS thousands of peo.
pic witnessed to their infinite wondermenl
and surprise. The height reached by this
stream was 250 feet. Some idea of the force
with which the water was thrown may be
learned from the fact that two or three
stones the size of mans fist, which had in
some manner got into the pipes, were thrown
into the air some distance above the sur
rounding buildings. The signal was given
to shut off the pressure, and the grandest
display of water-works the world has ever
seen was closed.
In the four tests preceding the exhibition
streams the water flowed through fif.y
feet of hose. The heights reached were az
follows:
Fourteen one-inch streams, 133 feet.
TWenty-tWo one-inch streams, l35 feet.
Thirty.two one-inch streams, 100 feet.
One two-inch stream, 220 feet.
One four-inch stream {horizonta), 4G5feet.
One threc-inch stream, 283.1 feet.
One four.inch stream, 1913 feet.
One fye-inch stream, 250.6 feet.
The heightreached by the vertical streams
WAS measured by mathematical Instruments
in charge of the following observers: L.. l..
Nichols, assistant engineer OF Rochester
water.works Byron Holley, assistant en-
gineer of New York State canals !; Thomas
Eyershed, chief engineer OF Rochester ana
Nunda railroad; John Cowman, eiyli en-
gineer and surveyor; Cyrus Beafdsiey, u.s.
sistant engineer aud surveyor; Daniel DfuI-
mond, with assistant, engineer aud surveyor;
John Ryan, assistant city surveyor John
Fitch, engineer and surveyor.
The amount Of water thrown per minute
in the various tests and the number OF gal
Ions which would lie THROWN In twenty-four
hours at the same rate a-e given in the fol-
lowing table. 1t must not be overlooked
that there,is no stop in the ineessant flow OF
the water. II is as easy to continue the
streams for ten hours as ten minutes.
