Mr. Nighthawk opened his coat, and showed me a brace of revolvers.

“I have these; but they are unnecessary, colonel.”

“Unnecessary?”

“I have an understanding with Swartz, and he with me.”

“What is that?”

“That we shall not employ the carnal weapon; only destroy each other by superior generalship.”

“You speak in enigmas, Nighthawk!”

“And yet, my meaning is very simple. If I can have Swartz arrested and hung, or he me, it is all fair. But we have agreed not to fight.”

“So, if you caught him to-night, you could have him hung as a spy?”

“Yes, colonel; but nothing would induce me to betray him.”
