"Mercy! mercy!" he cried, "take not the last glimpse of light from me! Now comes the Devil himself to rend me to pieces--Ha! let me not lie a corpse here in the dark--Mercy! mercy!" he howled, and pulled and tore at the cords which bound him. "Pray to thy God and Judge for mercy," said Aagé; "I cannot help thee." He then squeezed himself through the narrow opening, with the lantern in his hand, and pulled the trap-door after him, that he might not hear the howls of the madman; but was nearly falling down head foremost from the ladder, on hearing, to his dismay, that the trap-door, which had a spring-lock, fell and closed over his head. He felt now as though he were entombed alive. He had forgotten to take the key with him; and the faint howling of the robber soon seemed lost in triumphant laughter above the grave which had closed over him. Aagé grew dizzy, but recovered himself, and clung fast to the slippery steps of the ladder, while he continued to descend. At last he stood at the bottom: the descent was steep and deep, but it led to a narrow vaulted passage, which was so low as hardly to admit of his walking upright. The air was foul and suffocating, and he often trod on sprawling toads and other reptiles. He held up the lantern before him, but beheld nothing save the long narrow passage, to which he could discern no end; its direction, however, convinced him that it must undoubtedly lead to the castle. He went forward with hasty steps, and looked anxiously at the light in the lamp, which gleamed fainter and fainter. The air seemed not to contain sufficient nourishment for life and flame. He had hardly proceeded more than a hundred paces ere what he feared took place--the light went out in the lantern, and he stood in the dark. He felt a degree of alarm and a want of power and courage, which was quite foreign to his nature; at the same time he heard a hollow clang far behind, as if the iron trap-door had been again opened and clapped to. He involuntarily quickened his steps, but slipped every moment on slimy reptiles, and was often forced to pause in order to take breath, while the air he inhaled seemed to lame every limb and to contract his lungs. He was nearly sinking down in a state of insensibility; but he now thought he heard a sound as of stealthy steps behind him, and his increased apprehension inspired him with renewed strength. "Is any one there?" he shouted, and turned round; but no one answered, and there was suddenly a deathlike stillness again.
