parent to nearly every miner in Wis
consin, that, to properly and thore
oughly develop our great mineral re-
sources recourse must be had to
driving levels such machinery
pumps night and day without watch
ing or attendance | am, as you are
aware, an advocate of that rational
system Of drainage, yet, at the same
time, ] am fully aware that there are
many situations where it is next to
an impossibility to drain by q level.
Hence, to get az the mineral, pump
ing must be resorted to. But, pump
ing, as it is now, and ever has been
conducted, is rendered so expensive
that it must be good diggings in>
deed that can sustain it and leave a
margin of profit. This truth is SO
well and generally understood that
men are very cautious about ventur-
ing. Thus heavy bodies of ore, well
known to exist, lie unworlzed. Hence,
some means must be devised to lessen
the expense Of working these mines.
Can less expensive system or
plan be introduced? Can mechan>

or use a well>known lar Of nature
atmospheric pressure, with II pounds
on the square inch, and 1909 pounds
on the water of q ten inch pump, to
accomplish this very desirable object?
am Of opinion it can, and shall pro
ceed to explain as clearly as | can, the
manner in which | think it may be
done.
| must first, however, call your at
tention to the fact that if you were
to place pipe ofany diameter, %
feet in length, and an apparatus at
the top of that 3 feet in length, and
that apparatus is so constructed as to
form a vacuum within itself; sup~
posing this pipe is full Of water, the
water will rise three feet and jill it,
If it is 30, so, or 100 feet in diameter
Bear in mind the water is up, with
out the aid of either horse or steam
power, and that too distance Of 80
feet.
tell you, miners, there is no need
of this lifting Of water Water will
climb up it self if you will only bring
some ofthe immutable laws Of nature
to bear upon it. The idea of lifting
through pump open at the top, thus
lifting against a weight or pressure
Of atmosphere at the rate of 1909
pounds on 10 inch pump, appears
to me to be worthy Of some considers
alton. But this is what you have
been and still are doing. L wish to
call your attention to the absurdity
of this way of doing. Now let US
get at this air Pressure, or a Ne,0
Project for Pumping Mines" The APP
paratus is arranged thus; Two work
ing cylinders, the pistons Of bofh con-
nected by one piston rod. The low
or or vacuum cylinder, is II inches
in diameter The upper or steam
cylinder is 6 inches in diameter
| need not occupy space here in tell
ing how to rig the two cylinders on
the top of the pump, which is % feet
in length. Any person who has
worked about pumps will know how
to 90 about such job. To operate
this upper steam cylinder, you want
to have at the top a small fue or
tube.boiler and / inch pipe. leading
from Il down the shaft to this small
steam cylinder. When the piston
of this cylinder makes its upward
stroke, it will pull up the piston of
the larger or lower cylinder the piss
ton rod being connected to both, and
as YOU see at once, will cause a vacu,
um in the large cylinder, into which
the water will simultaneously rush,
with force impolling it of Il pounds
to every square inch, and this is sure
ly is force enough to accomplish the
work. Now, here is the water %
feet from the bottom Of the shaft,
without any lifting, driven or forced
up by simple application of one Of
natures laws If the pipe or pump
was-100 or 900 inches in diameter,
the same result would follow. | pre-
sumo here you will be inclined to
agree with me that there is room for
Improvement on our old, clumsy lum
bering system of pumping. Now.
the vacuum has been formed IN the
lower cylinder, and the water has
rushed in through a valve or opening
inwardly in its bottom end or where
