As a follow up to my review of Clive Carter’s Holman book can I say the book covers the installing of the Dorothea Beam Engine at Nantlle (1904/5). This is the most detailed account I personally have read of the engine’s installation. It appears to be based on the office diary of the Dorothea Quarry Manager, though as I noted in my review Clive Carter has been sparing on revealing his sources. In the book there is also a whole page picture of the front of the engine house taken in 1951. I wonder if this is a still from the Holman’s Film Unit coverage of the engine. Much to my amazement Clive Carter mentions that a ‘W H Curnow’ was sent, by Holman’s, to Nantlle in May 1905 to teach the local men how to drive the engine. This name ‘Curnow’ rang a bell with me and eventually I remembered that a ‘W H Curnow’ was the author of an old and very good Tor Mark Press book called, ‘Industrial Archaeology of Cornwall’. This particular book has no publishing date but my copy has the date 1969 written inside it by its first owner. If Mr Curnow was say, 25, when he went to Dorothea he must have been well in his eighties when he wrote the Tor Mark book. Does anybody know any more about him? For example, what he did he do in the over 60 year gap between 1905 and 1969! Russell Bennett
