"All right," said the boy, "then I'll take it off for you. But I'll have this gun handy, and if you try any foolishness you won't hold water when I get done shootin'."

Before long the helmet was off, and Jimmie was looking into as evil a face as he had ever seen. It was the face of a stranger, and yet there seemed something familiar about it.

"What sort of a game is this?" demanded the captive. "If you know what's good for you, you'll quit this cowboy business."

"Who are you?" asked Jimmie.

A snarl was the only reply. The enraged man was tugging fiercely at the rope.

"Quit it!" warned Jimmie. "I'll have to put you to sleep if you try that."

"You don't dare!"

"Don't four-flush!" the boy advised.

"Release me!"

Jimmie sat down and leveled the weapon at the struggling man.
