Cornwall being a land of mines has developed machinery and furthered invention in this direction. The most notable of the inventors she has produced is Richard Trevithick, who first made the high-pressure engine, and is still more remarkable as the early pioneer of motor traffic, putting his road locomotive on the Camborne highway on Christmas Day, 1801, and obtaining a speed with it of 12 miles per hour.
