"I thought not; hands up now or you are dead men. Quick!"
Jack made his decision in a moment. Much as he would have liked to fight it out, he determined upon a wiser course.
"Hands up, Frank," he said quietly. "They've got the drop on us."
He raised his hands in the air.

"They won't get me without a fight," declared the lad angrily, and, raising his voice, he cried:
"Come and get me, if you want me."
At the same moment he raised his revolver and fired.
"Here," cried Jack angrily, "don't be a fool. Give me that gun."
