Series 1: 4. A River of Invention

Paul discovers the source of the remarkable River Nith, high in a remote forestry plantation. Heading downstream, he hears the story of the Knockshinnoch mining disaster – how 116 men were saved from entombment after a massive earth collapse. \n\nAt Sanquhar, once famous for its unique and distinctive knitting pattern, Paul tries very hard to knit a glove before it all unravels. Kirkpatrick Macmillan was the man first credited with making a bicycle with pedals. Paul wobbles in his wake aboard a replica at Drumlanrig Castle, before heading south to Ellisland – once the riverside home of the poet Robert Burns. \n\nIn Dumfries, Paul learns how astronaut Neil Armstrong might not have walked on the surface of the moon without the optical skills of a local man. Journey’s end is at Caerlaverock Castle overlooking the shining sands of the Solway Firth.
