For Tingtang Mine. The mine was frequently spelt as "Ting Tang" or "Ting-Tang". This was the first Boulton & Watt engine ordered for Cornwall, in 1776, although it was the second one erected; Chacewater [see Portfolio 5/1295] was the first one at work. The engine was sold to Scorrier, also called Wheal Chance, in 1782, where it worked until Aug. 1784. According to the List of Engines made at Soho, it was then removed to Wheal Fat, where it started work in May 1785 and worked until Nov. 1786. Dickinson & Jenkins give the name of this mine as Wheal Let and say that it was part of the Scorrier mine [p. 341]. It was then removed to Halebeagle, part of the North Downs Mines, where it worked from Oct. 1787 to Jun. 1788. According to Dickinson & Jenkins [p. 342] by 1794 the engine was lying idle, completely worn out.
John Southern placed both the original Tingtang drawings and the Scorrier drawings of 1782 in a book entitled "Drawings made in Cornwall". This book was No. 28 in his list. However the original Tingtang drawings were at some point removed and placed in a book which the Drawing Office numbered 4 in their series of books of pre-1778 drawings. Henry Hazleton re-united the drawings during his re-organisation.
