Avon turned his attention to his relative, when he was astonished to perceive fully a dozen horsemen a short distance off between him and the ridge.

The first natural thought of the youth was that the party at the camp had ridden out to their help, but he instantly saw that such could not be the case, since there were so many of them, and it did not require a second glance to ascertain that each one was a mounted Indian.

But while it looked as if the Indians must be friendly from force of circumstances, their conduct justified the grave alarm Avon felt on first seeing them. Perceiving they were discovered, they broke into a rapid gallop beyond the unsuspicious Captain Shirril, spreading apart like a fan, as if they meant to inclose him in the circle beyond escape.

A shout from the young man caused his uncle to look around, when he discovered what was going on. He instantly touched his animal with his spurs and sent him swiftly toward Avon, who advanced to meet him.

“It means mischief,” was the reply. “I 263 believe some of them belong to the party that tried to burn our house.”

“Then they are Comanches?”
