"This," he said, with confidence, "will convince you that I speak nothing but the truth."

"My father's ring!" gasped Frank.

"Yes," bowed the man; "it is the ring that led him to one of the richest mines in the Southwest. He said that it would simply be necessary for me to show it to

you, and you would know that he sent me. Shall I call this evening, Mr. Merriwell?"

"If you please, sir," said Frank, bowing respectfully.

The boys were surprised, but Frank said he would explain some time later.

That evening the stranger called, as he had said he would. Frank had taken pains to run Harry out of the room, so they were quite alone. The boy locked the door, as a precaution against unwelcome interruptions.

The mysterious man introduced himself as David Scott, the confidential agent of Charles Merriwell, Frank's unfortunate father, who had spent the best years of his life and separated himself from his family and friends in the mad search after "phantom fortune."

At last Charles Merriwell had "struck it rich," and he was now a very wealthy man; but he was broken in health, and he often feared for his reason. As Charles Merriwell had been eccentric and unfathomable all his life while poor, thus he remained now that he was rich. Of late he had been seized by a conviction that he could not live long, and it was his desire to make a will that

would give almost his entire wealth to his son. But before he made such a will, Mr. Merriwell decided to know just what sort of a young man his son had become. As he did not feel like leaving his mine and going East to investigate, he sent his confidential clerk, David Scott.
