Never would he take any word of warning to the Texans.

Buried under the sea! He shivered all over and a cold sweat broke out upon him.
He lay a long time until some of the terror passed.

Then he sat up, and looked at the round hole in the cement ceiling.

It was about eight inches in diameter and a considerable stream of fresh air entered there.
But the pipe or other channel through which it came must turn to one side, as the sea was directly over his head.

He could not reach the hole, and even could he have reached it, he was too large to pass through it.
