Big Bob saw that he had made a mistake in talking with the shrewd youngster, and decided to get out of it the best way he could.

"All right! I'll tell you," he said. "A reward will be paid right down on the nail when a confession is filed with the prisoner. Now you know all about it!"

"Your imagination is working all right to-day," Fremont laughed. "The last explanation is more foolish than the first. You knew very well that the payment of the reward would follow conviction, and you know that I am innocent."

"Why do you say that?"

"Because you know who the real criminal is."

"That is not true!" thundered the other. "Now, I've had enough of this. You mog along and keep your mouth shut or it will be the worse for you."

Fremont knew very well that Big Bob was considering a desperate means of retrieving the error he had made in speaking of a friend who might be accused of the crime. The boy was afraid that he had gone too far in his desire to provoke the big fellow.

For there would be no one to ask questions if the boy should never leave the hills alive. Unless the Black Bears were within striking distance, no one would ever know what had become of him. He looked and listened again for some signs of his friends, but the slope behind told him nothing.
