Ilustrated article encouraging readers to visit the construction site of the Thames Tunnel. The illustrations show a transverse section of the route of the tunnel, a perspective view of the archways and the tunneling shield used to excavate the tunnel. Sir Marc Isambard Brunel (1769-1849), engineer and inventor, was at the forefront of civil engineering during the Industrial Revolution. His most remarkable undertaking was the Thames Tunnel from Rotherhithe to Wapping. Construction began in 1825, but was not completed until 1843, partly due to the workings being totally flooded in 1828, causing the project to be abandoned for several years. 50,000 people walked through the tunnel on the day it opened. Today it is part of the London Underground.
