The diving bell was halted and they gazed around sharply for some sign of the demons.
Not a monster of the deep was in sight.
The moss was torn up on all sides, and here and there lay parts of bodies and bones, but that was all.
"Perhaps they all killed each other," suggested Dave.
"Let us hope so," came from his father.
The mossy plain was now passed, and gradually the diving bell slipped down the slope of the valley beyond.
Here the light was not so good and they had to turn on the electricity.
At the bottom of the valley grew a number of submarine trees and bushes, with vines which sent up their swaying bodies several hundreds of feet into the crystal-like water.
At last the diving bell came to a stop at the very bottom of the valley, among the trees.
They signaled to stop lowering and then brought out a tiny searchlight which had been brought along.
