able to advance shoulder to shoulder with engineer and scientist and with them see the picture whole, he could share their sense of mastery and confidence and believe wholeheartedly in material progress. But so soon as science and the arts became divorced, so soon as they ceased to speak a common language, confidence vanished and doubts and fears came crowding in. He set out these ideas more fully in his book High Horse Riderless, a classic of green philosophy. A bridge (no. 164) on the Oxford Canal in Banbury bears his name (in commemoration of his book Narrow Boat), as does a centre at the boat museum at Ellesmere Port in Cheshire. A blue plaque to Mr. Rolt was unveiled in at Tooley's Boatyard, Banbury on 7 August 2010 as part of the centenary celebrations of his birth.
