Blue-cap

A mine spirit who long haunted Shilbottle Colliery near Alnwick. The industrious Blue-cap was said to have enormous strength, being able to toil for long hours. He assisted miners and expected to be compensated for his help. Every fortnight his wages were left in a corner of the mine. If they were a farthing below his due, the indignant Blue-cap rejected the money, but if it was a fathering above his due, he would leave the surplus where he found it.

The spirit appeared as a light-blue flame.
