"It is too dark for me to see very well."

"I am here to make you swear to give me what is mine. If you do it not, then you die!"

"And you will go to the electric chair at Sing Sing. Should you kill me to-night, Jalisco, you would be executed for murder."

"Paugh! I fear it not."

"Do you fancy you could escape?"

"I could."

"How little you reckon on the power of the law in this country. For you there would be no escape. You threatened my life, and that threat was heard before many witnesses. Those witnesses are all rich and powerful men. Should I be killed here and now, the first thing those men would do would be to bring all their combined influence to bear on having you arrested immediately, and convicted of that murder. Even if you were not guilty, and by some chance an unknown party should murder me, you would find it almost impossible to escape punishment for the crime. All those men would believe you did it, and they would bend every energy and the influence of their great wealth to carry you to the death chair. Did you attempt to prove an alibi, with all their influence and their wealth they would overthrow the proof, and show your witnesses were liars and perjurers. You cannot harm me without bringing destruction on yourself."

In this manner Frank forced the belief that he spoke the truth upon Felipe. Although he could not see the dark face of the Mexican, he felt that Jalisco had received his check.

"I have not come to kill you now," confessed the boy. "I want you to know I can do it. I want you to feel the constant danger. I want you to understand that when I am ready to strike I can do so, and strike to destroy. Perhaps not in New York or any great city like this shall I do it. I will follow you like a shadow. Where you go, there I will be. Unless you give me what I demand, I will some day kill you, having chosen the spot and time. Then I will escape, and no power may stop me. Fool of a gringo, you must give me my own! I will leave you in possession of the mine, but you must pay me one-half of all the money you make from it. It is the only thing that will save you. Señor Hagan asked for a big sum all at once, as he thought thus to get his share right away. I would have had him accept half the profit. Swear now that I shall have it! Swear you will pay——"

"Not a cent!" answered Merry grimly. "You have taken the wrong method of getting anything from a Merriwell. Not a cent shall you ever have!"
