He moved on in an oblique direction several feet, now creeping over the tops of the foundation arches, now skirting the extremities of protrusions in the ruined brick-work, now descending into dark slimy rubbish-choked chasms, until the rift suddenly diminished in all directions. The atmosphere was warmer in the place he now occupied; he could faintly distinguish patches of dark moss, dotted here and there over the uneven surface of the wall; and once or twice, some blades of long flat grass, that grew from a prominence immediately above his head, were waved in his face by the wind, which he could now feel blowing through the narrow fissure that he was preparing to enlarge. It was evident that he had by this time advanced to within a few feet of the outer extremity of the wall. 'Numerian wanders after his child through the streets,' muttered the Pagan, as he deposited his lantern by his side, bared his trembling arms, and raised his iron bar, 'the slaves of his neighbour the senator are forth to pursue me. On all sides my enemies are out after me; but, posted here, I mock their strictest search! If they would track me to my hiding-place, they must penetrate the walls of Rome! If they would hunt me down in my lair, they must assail me to-night in the camp of the Goths! Fools! let them look to themselves! I seal the doom of their city, with the last brick that I tear from their defenceless walls!' He laughed to himself as he thrust his bar boldly into the crevice before him. In some places the bricks yielded easily to his efforts; in others, their resistance was only to be overcome by the exertion of his utmost strength. Resolutely and unceasingly he continued his labours; now wounding his hands against the jagged surfaces presented by the widening fissure; now involuntarily dropping his instrument from ungovernable exhaustion; but, still working bravely on, in defiance of every hindrance that opposed him, until he gained the interior of the new rift. As he drew his lantern after him into the cavity that he had made, he perceived that, unless it was heightened immediately over him, he could proceed no further, even in a creeping position. Irritated at this unexpected necessity for more violent exertion, desperate in his determination to get through the wall at all hazards on that very night, he recklessly struck his bar upwards with all his strength, instead of gradually and softly loosening the material of the surface that opposed him, as he had done before. A few moments of this labour had scarcely elapsed, when a considerable portion of the brick-work, consolidated into one firm mass, fell with lightning suddenness from above. It hurled him under it, prostrate on the foundation arch which had been his support; crushed and dislocated his right shoulder; and shivered his lantern into fragments. A groan of irrepressible anguish burst from his lips. He was left in impenetrable darkness.
