Sappers and Miners

The action takes place in Cornwall, in and around an old tin-mine, possibly dating back to Roman and Phoenician days, for these people obtained much of the tin they needed to make bronze, from Cornwall, and many of the mines are still there, with many miles of workings, often going out far beneath the sea. According to Wikipedia: "George Manville Fenn (January 3, 1831, Pimlico - August 26, 1909, Isleworth) was a British writer. He worked as a teacher in Lincolnshire, until he became printer, editor and publisher of various magazines. He had eight children with his wife Susanna Leake, whom he had married in 1855. Most of his work consists of adventure stories for young readers, featuring Explorers, Smugglers, young Adventurers and Seamen. His adult novels offer critical social commentary on Victorian England, especially reconsidering economic questions."
