title: ["Earth rays"--an underground phenomenon?].
abstract: According to reports in the Norwegian lay press, a lot of illness can be ascribed to "earth rays". Earth rays are presumed to form a square pattern, but can only be demonstrated by dowsing. No documentation has been reported which supports their existence. However, many patients have experienced considerable relief after a protecting copper net has been placed under their beds. Four dowsers participated in an experiment where, independently of each other, they were to demonstrate the pattern of earth rays in a gymnasium. Four supervisors ensured that the dowsers could not communicate with each other during the experiment. As it turned out, they came up with four totally different patterns. Thus, any protective treatment prescribed by the dowsers seems to be based on pure chance.
