The call instantly attracted the attention of Vorlange and his companions. They turned toward the speaker, and now there remained nothing for Rasco to do but to run for it, and this he did at the top of his speed.
As long as he could he kept out of sight behind the bushes. But soon Tucker caught sight of him.
"Halt, or I'll fire!" came the command.
Tucker spoke first, and several others followed. As Rasco was now in plain view, and as each of the enemy had a firearm of some sort aimed at him, it would have been foolishness to have thus courted death, and the man of the plains halted.
"It is Jack Rasco!" cried Vorlange. "Boys, this is Pawnee Brown's right-hand man!"
"I know him!" growled Tucker. "Rasco, you're in a box now and don't you forget it. You've been spying on us."
"Make him a prisoner," said another of the cavalrymen, an under officer. "If he is a spy we'll have to take him back to the fort and turn him over to the captain."
A minute later Jack Rasco found himself a close prisoner. It was destined to be some time ere he again obtained his liberty. Thus were his chances of helping Pawnee Brown cut off.
