He opened the portfolio idly now, and as he did so his gaze fell upon the map which showed the wooded hill and the position of the lonesome shack upon its summit. He called to mind with what pride he had traced his own blazed path up through the forest and how Roscoe had followed him, plying him with questions. Then, suddenly, like a bolt out of the sky, there flashed into Tom's mind a suspicion which, but for his generous, unsuspecting nature, he might have had before. Was _that_ why Roscoe Bent had been so interested in the little hunting shack on the mountain? Was _that_ why he had asked if any one ever went up there; why he had inquired if there were fish to be caught in the brook and game to be hunted in the neighborhood? Was that why he had been so particular about the blazed path, and whether there was a fireplace in or near the shack? Had he been thinking of it as a safe refuge, a place of concealment for a person who had shirked his duty? "He could never live there," said Tom; "he could never even _get_ there." As the certainty grew in his mind, he was a little chagrined at his own credibility, but he was more ashamed for Roscoe. "I might have known," he said, "that he wasn't really interested in camping.... He's a fool to think he can do that." To Tom, who longed to go to war and who was deterred only by his promise to Mr. Ellsworth, the extremity that Roscoe had evidently gone to in the effort to escape service seemed unbelievable. But that was his game, and Tom saw the whole thing now as plain as day. It made him almost sick to think of it. While he, Tom, would be handing badges to the throng of proud and lucky young men just fresh from registering, while he sat upon the platform and listened to the music and the speeches in their honor, Roscoe Bent would be tracing his lonely way up that distant mountain with the insane notion of camping there. He would try to cheat the government and disgrace his family. "I don't see how he could do that--I don't," said Tom. "I wonder what his father would say if he knew.--I wonder what Miss Ellison would say. I wonder what his mother would think." He looked down again into Barrel Alley, and fixed his eyes upon the tenement where he and his poor mother and his wretched father had lived. But he was not thinking of his mother now--he was thinking of Roscoe Bent's mother and of his troubled father, going from place to place and searching in vain for his fugitive son. "If I told him," thought Tom, "it would queer Roscoe. It wouldn't do for anybody to know.... I just got to go and bring him back.... Maybe they'd let him register to-morrow. He could say--he could say anything he wanted to about why he was away on the fifth of June. If he comes back they'll let him register, but if he doesn't they'll find him; they'll put his name in newspapers and lists and they'll find him. I just got to go and bring him back. And I got to go without telling anybody anything, too."
