Knock, Knock… (Who’s there?)
Knockers or Tommyknockers, are believed to be goblins or sprites that live in the deep, dark mining tunnels. They are usually considered to be helpful and are said to use knocking to guide miners towards riches or warn them of impending dangers, such as roof collapses or cave-ins. Some traditions hold that Tommyknockers are the spirits of those who died in earlier mining accidents. Old school miners (like Duck - yes that's his name - shown above) are very superstitious about Tommyknockers.
