As Babbage delved more deeply into machinery, he realized there was a lot he could learn from other artisans. Soon, he was touring craft and manufacturing establishments all over England and in Scotland. Sometimes Georgiana accompanied him, making a holiday of the trip.

Since 1825, Marc Brunel had been building a tunnel under the Thames River in London’s east end. This was a massive undertaking—when completed, the tunnel was 1500 feet long, 37 feet wide, and 23 feet high. Because of many technical and financial difficulties, the tunnel was not completed until 1843, at a cost approaching £300,000. Charles may well have wondered how the government could afford so much for a tunnel and be so stingy over his Difference Engine. The Babbages were shown the tunnel site by Marc’s son, Isambard Kingdom Brunel, who was overseeing the work though he was only 21.
