Dory continued to creep from tree to tree until he could not have been more than a couple of rods from the concealed night wanderer. If he had not believed the man had a gun in his hand, he would have left his concealment and gone about his business; for he had come to the conclusion that the affair, whatever it was, did not concern him. But he felt a little bashful about leaving, lest the gun might go off, and the shot accidentally strike him. The next minute he was confident that he heard footsteps in the road. Before he had time to satisfy himself fully on this point, the gun in the hand of the stranger went off; and its going-off proved to Dory that it was a gun, as he had supposed, and even believed. "Help! help!" shouted some one in the road; and the voice proved that there was some one there. Scarcely had the word been uttered before the man in the bushes broke from his place of concealment, and rushed towards the road. Dory was too much interested in the affair to remain at a distance any longer. It was none of his business; but it was plain enough that the mysterious stranger had fired his gun at the person who shouted for assistance from the road. Dory reasoned, that, as he had fired the gun once, he could not fire it again without reloading it; and he had not had time to do this. But there was some sort of wickedness in progress, and Dory ran with all his might to the road; and, even if he had not run with all his might, it would not have taken him a great while to accomplish two rods. When he came to the opening, he saw one man spring upon another. The former dropped the gun he carried in his hand, and it was plain that he had fired the shot. The two men clutched each other, though one of them tried to say something to the other. Dory had lots of blood in his veins, and it began to boil as though it was over a hot fire. All his sympathies were with the man who had been attacked. The other had crept upon him like a thief in the night, had fired at him, and then had followed up the attack with a hand-to-hand onslaught. "Don't, Pearl!" pleaded the man who had been attacked. "Consider what you are doing! You will ruin yourself! You are sure to be discovered, even if you kill me!" Dory did not wait to hear any more. He had a strong impulse to take a hand in the affair, though it was none of his business. The stranger who had wakened him from his slumbers was back to him, and the boy thought his opportunity at the present instant was too good to be lost. The supperless wanderer flung himself upon the shoulders of the assailant, and grappled him around the throat with all his strength. He was well aware, that, if he failed at the first dash, his chance would not only be gone, but he would be in danger of being entirely wiped out by his intended victim.
