“Ho, my man, I’m back sooner than you expected me!” he said, as he once more bent over the rascal. “Well, I’ve come to make a trade with you.”

Again he showed his revolver, then took the gag from the man’s mouth.

“What d’yer want?” the fellow growled, in a slow way, for his mouth was sore and stiff.

“Your clothing. I’m going to take these cords off of you—every one of them, so that you can strip. I want you to slide out of this suit as quick as you can.”
