Sometimes it is a bit like being an archaeologist. As we walk across the island glimpsaes of previous lighthouse keepers lives can appear infront of us. In the past rubbish was never taken off the island but burnt or buried in one of the many gulleys. Puffins, rabbits and weather mean that some of those rubbish dumps on the island sometimes get uncovered and treasure can then be found.
And the 1934 penny found right next to the North Horn which was built in 1938, perhaps dropped by a workman sweating away on laying the concrete for the structure?
