Jack did not know what all this meant, and yet one thing seemed certain--he must stop this man and find out what he had been doing. Yet to stop a man on the road he knew was pretty serious business, and might very likely lead to shooting. He had traveled enough on the prairie and had associated enough with older men to be cautious about getting into trouble; but here was a case where trouble seemed to be coming toward him so straight that he could not avoid it. For the first two or three moments the rider seemed not to notice Jack, but when he did so, he checked the speed of his horse, and looked uncertainly to right and left, as though seeking some way of escape. By this time Jack had stuck his spurs into Pawnee, and was riding fast toward the approaching man. He had his hand on his six-shooter, ready to draw it at the least sign of trouble. As they drew near to each other the young man made a motion as if to put his hand on his pistol butt, but Jack called to him sharply, "Hands up!" and drew his pistol. The young fellow's hands flew up in the air, while he stopped his horse. Jack rode around and coming up behind him on the right side, still holding his pistol ready, reached over and took the young man's gun out of his holster, and then ordered him sharply to turn around and ride in front of him toward the house. He watched him closely, for it was possible that somewhere about his person the man might have another pistol, but the young fellow seemed to have no desire to do anything save what he was told. His nerve had wholly left him. They trotted up to the door of the ranch, and Jack called out for Mr. Powell, Charley and Mrs. Powell, and a moment later a tall, handsome, brown-haired girl appeared at the door, holding a six-shooter in her hand. Jack instantly recognized her as his old friend Bessie, but Bessie grown out of all likeness to the slim-legged little girl that he had known half a dozen years before. "Hello, Bessie!" called Jack. "You don't know me, I guess, but I am Jack Danvers, just over from Mr. Sturgis' ranch. I heard a shot and saw this man running away from the house, and stopped him. What has happened? Do you want him, or shall I let him go?" "I don't know, Jack," Bessie answered; "we'll have to think about that. He ought to be tied up for a while anyhow, until we can tell you what has happened, and can decide what to do." "Well," said Jack, "the first thing is to take his weapons if he has any. Here is the six-shooter he had when I stopped him. Will you hold it, and keep an eye on him while I search him? You used to be able to shoot when you were a little girl." "I guess you will think I can yet, Jack," said Bessie. Jack now noticed that she looked very white. "That man's partner is in here, and we will have to do something with him."
