Doc Sleep With One Eye Open

Doc and his men were tired--they had not slept a wink the night previous. Although the satanic noises within the crater were as fearsome as on the night before, they were becoming accustomed to them. Noises that made their ears ring and icicles roll down their spines now worried them no more than passing elevated railway trains bother a dweller in the Bronx.

But Doc had developed a sort of animal trait of sleeping with one eye open. He heard a faint noise. He thought he saw a light some distance away.

Later, he was sure he detected a distinct, dragging noise very close!

The sound stopped. Nothing immediate came of it. Doc dropped off to sleep. Too many monsters were prowling about continually to be bothered with one noise.

A loud shuffling beneath their trees aroused him again. He listened.

There seemed to be scores of great beasts below!
