Abstract
“Lord how this world improves as we grow older,” reads the caption for a panel in the “March of Intellect,” part of a series of colored etchings published between 1825 and 1829. The artist, William Heath (1794–1840), shows many futuristic contraptions, including a four-wheeled steam-powered horse called Velocity, a suspension bridge from Cape Town to Bengal, a gun-carrying platform lifted by four balloons, and a giant winged flying fish conveying convicts from England to New South Wales, in Australia. But the main object is a massive, seamless metallic tube taking travelers from East London's Greenwich Hill to Bengal, courtesy of the Grand Vacuum Tube Company.
