In Myth and Magic of Northumbria, Coquet Editions 1992
There is a tale of a man who decided to dispel the myth of the mischevious dwarfes who inhabited the Simonside hills and waylaid strangers by spending a night in the hills.
He wandered about for some time and saw nothing and so decided to pretend he was lost and in the local dialect shouted “Tint! Tint!“.
Immediately he saw a light in front of him.
To cut a long story short he found himself surrounded by ugly dwarves, each carrying a club and a torch, their evil faces twisted with menace. The man falls unconsious and lays until dawn. When he awakes the dwarves had gone.
