Here is a short but interesting set of observations by a member of the BSD. While dowsing on board two different ships during separate cruises, he detected “harmful” Earth rays. These lines, approximately 45 degrees to the long axis of the ship, were in fixed positions, irrespective of whether the ship was sailing, or in port. The “frequency” of the lines onboard ship was about the same as the “Earth rays” he has dowsed on land. Needless to say, the dowser could make no sense of his observations.

Here he first notes his observations of the lines aboard ship, “Dowsing whilst on a cruise in the Mediterranean” by Peter Pengilly:

In this article he includes further comments and a diagram of the ship. He also sets a challenge to readers to trace the energy one themselves and provides his own results in the following edition, “Dowsing aboard ship” by Peter Pengilly:

Although only one dowser’s account, it is such exceptional occurrences that beg the question, just what is the nature of these so-called Earth rays? Are they really of the Earth, or are they more a product of the dowser themselves?
