Now turns out the stone in question is not on Bodmin Moor but on Dartmoor..it is the end stone at Merrivale.
The gentleman who contacted me is out to prove that stones do not have these powers (nor do trees in Essex). He feels people should not be allowed to make statements like this without scientific proof.
As someone who does not believe in ley lines and never gets any 'feeling' when near stones I would be interested in what others think about his thoughts. I know many of you do believe in the powers stones can have and that is fine by me, but scientifically can this ever be proved?
