He was really in the heart of the coral reef. But he looked in vain for the professor.
Von Bulow was not in sight.
Was the professor dead? Had he become the victim of some submarine monster? The captain did not believe this.
He proceeded to examine critically the bed of sand upon which he rested.
There were the marks of footprints and the part impress of a man’s form. Von Bulow had fallen here.
But he had also arisen, for the footprints here led into one of the passages.
Filled with excitement, Bell proceeded to follow them. He was soon deep in the passage.
And as he pressed on he saw a flickering light in the far distance.
Suddenly the light ceased to move and remained stationary. Bell knew what it meant full well.
The professor had turned and saw the captain following him. He was waiting for him.
