AN ARTEsiaN TEST.

Fro.ss the New City Well 925 Gallon,
Per Minute Flows int the keser
yoir, with Considerable Waste at tn,
Meuth of thu Well and Loss OF Fore,
A 1900 Gallon Wei.
On Saturday evening, in the presence
of the water committee OF the city
council, the water from the new artesiar
well was turned into the top of the res
erveir through q six inch iron pipe ex
tending thlrty-three feet from the mouth
of the well. It was late in the evening
VIXEN q. ]. Anderson, water superintend
ent, completed his preparations for the
test. From the perpendicular arm Of
the I pipe through which the water wa
discharged he carried upward to the top
of the south reservoir an extension
reaching an opening through which the
water was to be discharged into the reser-
voir. The end of the horizontal arm of
the pipe through which the discharge
was spouting had been prepared for
the reception of of an iron slide valve,
which was to cut off the discharge and
turn the water upward into
the reservoir. Inside the
south reservoir Mr.. Anderson
had placed q six inch perpendicular
pipe, reaching TO the top of the
reservoir. The north reservoir was con-
nected with the south reservoir, about
fifteen feet from the bottom, by q six
inch iron pipe. By this arrangement
when the twin reservoirs were filled the
water would run out of the waste pipe
as fast as it ran in from the well pipe,
keeping the reservoirs all the time filled
with fresh water.
A. W. Barber was posted on duty to
keep the Official record for Mr.. Anderson
and his report runs as follows:
cat precisely nine O'Clock the slide
valve was shut down on the lower orfice.
The water instantly appeared at the
upper pipe mouth, twenty.four feet
higher and poured into the tank
through a hole cut in the roof. The
stream was of SIX inches diameter, round,
smooth and much less forcible thar 1t
was below. The waiting spectators built
a fire in front of the tanks to light up
the gauges and time the flow.
ga mathematician had previously been
inside the reservoir and found with q
tape line that the inside diameter at the
bottom is twenty-nine feet four inches
The amount of water required for one
foot in depth is 5,055 gallons, or 421
gallons per inch. In thirty Minutes five
feet six inches of water had been re-
celved. All subsequent observations
proved the same rate of flow, the narrow
ing of the upper portion causing hardly
any pereeptible difference. Each foot
of depth was added in about five and q
half minutes, showing that the great
pipe delivered the water at the top of
the tank at the rate of 925 gallons per
minute, or about a barrel of thirty-one
and q half gallons every two seconds.
But there were leaks at the slide valve,
and the stream flowing from them was
estimated at from se~vsnty-Gve to one
hundred gallons per minute. Had the
valve been closed tight there is no ques-
ton but that fully 1000 gallons per
minute would have flowed from the
pipe thirty-three feet above the hill top.
Hence there is a difference of just one
atmosphere, or fifteen pounds, per
square inch between the flow as first
opened ana the present stream. Esti-
mates will vary as to the quantity dis
charged below when the tall pipe, with
diminished force gives 45,700 barrels PSF
day"
Sat the end of eighty-five minutes
the water had risen fifteen feet and q
half and began to discharge through.
the six inch tubs which
joins the two 100000 gallon reservoirs.
The north reservoir contained less than
eight feet. At the end of another hour
both tanks were filled to the depth of
seventeen feet and as their dry upper
portion leaked very fast, the valves was
opened and the flow into the tanks was
stopped. The new ak inch discharge
pipe rises on the inside so that the water
must be over eighteen feet deep before
it will carry off any water. The total
inside depth of each reservoir is nineteen
feet two inches.
ut will now be perfectly easy, after
these accurate observations, to determine
whether the volume decreases hereafter
or not. AT any time one OF the tanks
can be drawn off till empty, and filed
from the well-pipe while the rate Of
delivery is carefully noted. The stream
will now run a reservoir full in an hour
and forty minutes, or rather less, when
ali leaks are closed.
1.-THE only connection between the
Tanks he's heretofore been by three little
one inch tubes at the bottom. In case
of o great drain for a large fire they
would be very inadequate.
ga Jet black muddy sediment of iron
rust, about an inch deep, was at the bot.
tom of the reservoir covered with fresher
red rust. 1t is agreed that the new vein
of water does not carry SO much iron and
sulphur, as the former we'll.
"The velocity of the water through
the pipe is now certainly proved to be
ten and a half feet per second, or 633 feet
