Not one of the pirates disturbed them, and on the following morning Frank drove the Jove high in the air, and sent her along the coast.

Indeed, she mounted so high that she rose above the clouds in the rare upper atmosphere.

Frank had control of the wheel when Zamora came in with his boy and asked him:

“Are you going home now?”

“Not yet,” Frank responded, shaking his head.

“What is there to keep you in this neighborhood?”

“Since I started in fighting the Terror of the Coast,” answered the inventor, “I have concluded to not leave my task unfinished. Captain Diavolo is still at large. He yet has his steamship to scour this gulf. I am determined to find the man and his craft, and put them where they will do no further harm.”

“It is a noble resolve, and has my heartfelt sympathy,” said Don Zamora, earnestly. “And by your leave, senor, I shall remain aboard until your purpose is finally accomplished, compadre!”

Frank was satisfied.

He spent several days after that searching for the villain, but failed to find him.
