Frank was quickly in the pilot-house.
He grasped the wheel, and then the boat shot forward like a flash. The Dolphin was a very speedy craft.
The whale would have been quickly impaled on her ram, but at that moment it seemed to take a sudden freak and dived.
Down it instantly went out of sight. Frank was for a moment chagrined.
But he instantly took active measures to pursue. He pressed the reservoir valve and the Dolphin sank.
Down for a hundred feet she went.
Frank did not believe that the whale would dive deeper than this.
With the descent of the Dolphin Frank instantly pressed the electric valve.
Instantly the sea for a great radius about was illumined.
Frank saw the distant form of the whale racing before the light like mad.
