Pieces trotted out by office workers who have been told to “write something about Gilsland” do not count as folklore. Almost without exception such accounts are uncritcal, unreferenced cut & paste exercises from the handiest guidebook. The content of most guidebooks to Gilsland can be directly traced back to the flurry of publicity and synthetic folklore which appeared around the 1860/70s.
The information about the midsummer expeditions is more interesting, but I would like to see a contemporary report, for instance from a newspaper.
