For Chacewater Mine. According to Dickinson & Jenkins [p. 340] this engine was a reconstruction of a 72 inch engine erected by John Smeaton. However the majority of the materials appear to have been new. According to the List of Engines made at Soho, this engine was "worn out and entirely destroyed" by Aug. 1785.
