"Who is the Copper Princess, papa?" asked the girl, who, though bewildered by the old man's extravagant statements, could not help but be interested in them.

"You are, my darling, you are a copper princess; but the name also applies to your mine, and was given to it before you were born. 'Darrell's Folly' is what men, in their ignorance, call it now, but in one week's time it may assume its rightful title, and thereafter the fame of the Copper Princess will spread far and wide."

"But why not let people call the mine by its real name now, papa? What difference will one week make?"

"Because," replied Ralph Darrell, bending towards his daughter, and lowering his voice almost to a whisper, as though fearful of being overheard, "in one week's time—only one week from this very day—the contract will expire, and the heirs of Richard Peveril can make no claim."

"Richard Peveril!" cried the girl, with a sudden recollection; "why, papa, that is the name of the young man who was in the cavern to-day, for he told me so himself. He is the same, you know, who came for your logs."

For an instant the old man glared at his daughter with an expression so terrible that she shrank from him frightened. Then it cleared, and in his ordinary tone he said, gently:

"I wish, dear, you would go and change your dress. I don't like to have you wear this boy's costume in the evening."

With only a moment of hesitation the girl obeyed him and left the room.

She had no sooner disappeared than the strange expression that he had so successfully banished for a minute returned to the man's face, and, possessing himself of a revolver, he proceeded to load it. As he did so he muttered:

"I must do it for her sake, though she must never know. Richard Peveril shall not be given an opportunity for making his claim. If he is really in the cavern he must not be allowed to escape from it alive."
