“My friend, you shall have your rights. That treasure every bit belongs to you, and yours it shall be.”

“Thank you a thousand times!” cried Harding, eagerly. “Oh, do you really mean to say that you will help me to recover the Incas treasure?”

“I do,” replied Frank.

“Half, yes, two-thirds of it shall be yours. I only ask enough——”

“Not one cent!” replied Frank, quickly. “I do not want money. I am rich enough.”

Harding was almost delirious in his great joy.

He alternately thanked and blessed his young benefactor.

“If I can return to America with a fortune, and claim Mabel Dane as my wife,” he declared, “I shall be the happiest man in the world.”

“If it is in my power to assist you to do that, I will do it.”

Frank now proceeded to show Harding the wonderful mechanism and construction of his air-ship.
