I am unsure as to the maintainability of a credible scinece-experiment story. For that there is a ring of filings around the destroyed church, we could not possibly be asked an explanation to be giving. This one may be a hole in the story, but it may not matter. It proves nothing anyway, even if it is established that there is a ring of iron filings around the church, and that Jim bought filings. Nothing logically follows.
Nothing illogically follows.
It is only a vague connection and tenuous and too far before mass anyway. Maybe there was a hole in the bag, and Jim walked around with Stoatley and myself when Stoatley took rubbings. They are not going to find it. I think we might as well not know anything about it.
