The Mecca to which the curious OF
the Constoek make pilsrimasss now is
the. Chollar.N orcross.Ssvsge shaft, and
the shrine Of their devotohs il the new
hydraulic pumping engine which Is In
place. It IL . curious structure and well
worth seeing. In general appearance 1t
might be iiksnsd to . mighty octopus,
the pipes for steam and feed and force
resembling ~tsntaclss ooiled around and
upon the body.
This monster ID . compound oondsns-
ing, direc.-seting engine. the cylinders

cylinder 20 inches in diameter; stroke,

needed with this engine. Regular
plunpers are attached to the orosshead
and that Is about all there 10 to IL except
feed aud exhaust pipes. Pumps are
usually used to raise water, but these
pumps at the engine are to send water
down 2400 feet.
One at Arst thought would hardly 40

vet before II will be in operation. The
only materials lacking are the pumps Tor
the 24O0 level. The feed and exhaust
columns are on hand and nearly all In
place. The sccumulstor 10 also on the
around but the work Of setting It up has
not yet been commenced although the
foundation for II has been laid.
And that accumulator 10 going to DO .
singular thing also. II will consist OF .
heavy iron tube about 60 feet high and
az feet in diameter and solid at the top
where compressed air will be confined
above Q column OF water giving the re-
quired pressure OF 1850 pounds per
square inch. Into this accumulation the
pumps at the engine will force the water
which 10 10 act as q motive power. The
pressure will be transmitted through the
water In the column to the 2400 level
where IL will operate the main pumps
and exhaust itself into . return pipe
which will reconduot It to the surface 10
bs sgain forced into the aocumulator and
thus continue In use. -.
The force exsrted ct the surface will
lose little by transmission through the
column Of water. as thu weight Of the
column in the exhaust pipe will DO bal.
anced by that In the feed pipe; hence
the working force Of the water at the
24OO level will be about 1000 pounds per
square inch. The usual working force
Of steam Is from lU0 to l2O pounds.
The iron pipes must, however, sust in
not only the pressure given above, but
the weight OF q column Of water 24O0
feet high. The combined pressure will
be simply immense at the bottom-about
5000 pounds in all per square inch.
II the water could be obtained without
too much cost, much OF the force eIerted
on the surface could be spared. as BY
discharging the water used into the
Sutro tunnel o working force equal to
that Of the weight OF q column OF water
1900 feet In height could be gained
without the accumulator or engine. But
the cost OF the water used would at this
place be too great to allow 1t to escape.
hence II is to be used over and over. and
when the pipes and tanks are once filled,
very little more will be needed.
The pumps operated ON the 240O
level will be l5-inch %plungers and In
double column. 1t was intended to give
them q capacity Of 1000 gallons per min
ute; but Ia the construction OF the ap.
paratus q margin has been allowed
which will probably increase the capac-
ity to 1000 gallons. The present pumps
have O capacity Of 1000 gallons per min-
ute. When the new pumps are In OPP

It will be seen by the foregoing, which

new pumping machinery Of the @. N. q.

this hydraulic apparatus. It 10 com.

There will be no breaking OF bobs or OF
