Jim loosened his belts and allowed his holstered guns to drop to the ground. While Jack was gathering the scattered letters together, Jim thought hard. Jack must not find the letters he had hidden. He was sure one of them contained the proof he needed. Suddenly the freckle-faced outlaw laughed aloud.

“Jack, yuh sure is a hell of a gun fighter. When yuh slipped, I could have potted yuh easy!” he taunted.

Jack Allen started, but made no reply.

“I was so darn sure yuh was stalkin’ about town tryin’ to make yourself tall that I got a bit careless,” Jim continued.

“What fool idea did you have when yuh done this?” Jack said angrily.

“Hell, I was playin’ a joke on yuh!” said Jim, with a taunting grin.

“Yuh won’t think it a joke much longer! Damn yuh! I could have let most things pass, but yuh robbed the United States mails an’ you’re goin’ back with me!” Jack hastily closed the mail sack. He hooked Jim’s two gun belts over the pommel of the outlaw’s saddled gray and then swung into the saddle.

“Yuh climb onto that nag I rode,” Jack ordered.

“’Fraid I’ll run for it?” his twin asked sneeringly.

Then the two started back toward town. Jim sighed with relief.
