Halliwell Boggle

Between Atwick and Bewholme, at the foot of the hill on which Atwick church stands, there is a spring and pool of water overhung by willows haunted by the Halliwell Boggle. A boggle is an imaginary hobgoblin, without any special form, causing fear and terror. — [Folk-Lore of East Yorkshire’ by John Nicholson (1890)]
