Without a moment's hesitation he set out for it, as fast as the unknown and rugged way would permit.

Yet again turning a corner, led by the dim light, he spied something quite new in his experience of the underground regions--a small irregular shape of something shining.

Going up to it, he found it was a piece of mica, or Muscovy glass, called sheep-silver in Scotland, and the light flickered as if from a fire behind it.

After trying in vain for some time to discover an entrance to the place where it was burning, he came at length to a small chamber in which an opening, high in the wall, revealed a glow beyond.

To this opening he managed to scramble up, and then he saw a strange sight.
Below sat a little group of goblins around a fire, the smoke of which vanished in the darkness far aloft.
