Underground Rivers - University of New Mexico

Chapter 10 -- Geophysical, Pnuematic and Electromagnetic Engines
found a rapid subterranean stream at a depth of about 120 feet, and it is supposed that the air
is sucked in by friction and carried along until the water rises as a large spring.
McCallie's logic is circular, of course, the water dragging the air and the air powering the water,
but then again, understandings that seem logical to us may well be dismantled in the century to
come.
Richard's apparatus made use of the injector principal to
supply relatively small volumes of compressed air at low
pressure. A small jet of water projected through a tube of
gradually increasing diameter sweeps a larger volume of air
into a receiver where the two are separated. Efficiency is
increased by a projecting step in the injector tube, or by
giving the tube the form or an undulating curve, deflecting
the jet to completely fill the passage.

We'll pursue the modern understanding of geomagnetism in Chapter 45, but here we can note
what's been widely understood for centuries, that our globe has magnetic properties.
A relationship -- or lack thereof, we may come to conclude -- between underground rivers and
electromagnetism might be manifested in one of three manners.
As an electromagnetic field emitted by subterranean waters revealing the water's presence, a
hypothesis we'll consider in Chapter 46, Finding the Underground Waters.
As an electromagnetic field emitted by subterranean waters altering our terrestrial environment,
allegations we'll weigh in Chapter 87, The Paranormal.
As an electromagnetic engine for the propulsion of subterranean water. With discovery of a
relationship between magnetism and electricity -- what we now know to be an electromagnetic
field -- it is not surprising that early investigators hoped that this new science might resolve
geophysical perplexities, how water seemed to rise to mountain tops, for example.
