And then they stepped out of the shade of the viaduct into the sun again, and Archie’s smile went suddenly from his face. They were at the penitentiary. The long wall stretched away, lifting its gray old stones twelve feet above their heads. Along its coping of broad overhanging flags was an iron railing; coming to the middle of a man, and at every corner, and here and there along the wall, were the sentry-boxes, black and weather-beaten, and sinister because no sentry was anywhere in sight. Archie looked, and he did not hear the dénouement of the sheriff’s story, which, after all, was just as well. Midway of the block the wall jutted in abruptly and joined itself to a long building of gray stone, with three tiers of barred windows, but an ivy vine had climbed over the stones and hidden the bars as much as it could. A second building lifted its Gothic towers above the center of the grim facade, and beyond was another building like the first, wherein the motive of iron bars was repeated; then the climbing ivy and the gray wall again, stretching away until it narrowed in the perspective. Before the central building were green lawns and flower-beds, delightful to the eyes of the warden’s family, whose quarters looked on the free world outside; delightful, too, to the eyes of the legislative committees and distinguished visitors who came to preach and give advice to the men within the walls, who never saw the flowers. Archie and the sheriff turned into the portico. In the shade, several men were lounging about. They wore the gray prison garb, but their clothes had somehow the effect of uniforms; they were clean, neatly brushed, and well fitted. They glanced up as Archie and the sheriff entered, and one of them sprang to his feet. On his cap Archie saw the words, "Warden’s Runner." He was young, with a bright though pale face, and he stepped forward expectantly, thinking of a tip. He was about to speak, but suddenly his face fell, and he did not say what had been on his lips. He uttered, instead, a short, mistaken, "Oh!" The sheriff laughed, and then with the knowledge and familiarity men love so much to display, he went on: "Thought we wanted to see the prison, eh? Well, I’ve seen it, and the boy here’ll see more’n he wants." The warden’s runner smiled perfunctorily and was about to turn away, when Bentley spoke again: "How long you in for?" he asked. "Life," said the youth, and then went back to his bench. He did not look up again, though Archie glanced back at him over his shoulder. "Trusties," Bentley explained. "They’ve got a snap." In the office, where many clerks were busy, they waited; presently a sallow young man came out from behind a railing. The sheriff unlocked his handcuffs and blew on the red bracelet the steel had left about his wrist. "Hot day," said the sheriff, wiping his brow. The sallow clerk, on whom the official air sat heavily, ignored this and said: "Let’s have your papers."
