Classic, originally published in German, based on the research in the 1930’s on “earth currents” – distinct telluric zones and linearity which display geomagnetic disturbances documented in residences, and in rural areas and correlated to their biological effects on humans, fauna and flora.
These zones can be verified with geomagnetometers and other tools.
