Oh, if Mrs. Chester could have slept for one hour like that little creature at her feet. But the poison seemed kindling afresh in her brain; her fancies grew wild and terrible; she was climbing mountains, sinking deep, deep, deep into the very bowels of the earth, where serpents coiled and hissed, and writhed with horrid joy as they saw her descend. Now she clung to the point of some sharp rock, holding on with her fingers, while those huge serpents trailed themselves upward, crawling slowly from the abyss from which she was saved only by the grip of her own slender fingers. Then you knew by her voice that the scene had changed. She was pleading for Chester--pleading with low broken tones, that would have touched a heart of stone. She besought the Mayor not to wrong her husband, not to press and wring his proud spirit so cruelly as he had done; and then she believed that her sweet eloquence had prevailed, for her lips trembled with thanks; she murmured nothing but soft blessings upon the man who had been to her worse than a murderer. Another change, and she passed on to some new hallucination, visionary as the last, for day and night her brain never rested. When they questioned her, the poor woman always answered that she was not ill, that nothing was the matter, nothing whatever--she only wondered the people would tease her so with inquiries that had no meaning. Another night came on, and again Mary prepared herself to watch by the sick. The few hours of slumber she had obtained, made quite a new creature of her. She was resolved to be doubly vigilant--that no one of the suffering persons around her should lack nourishment or care. How cheerful and strong the little creature grew, as a sense of her power to accomplish good increased upon her. It was strange, but after the first few minutes she never once thought of the danger. There she was, feeble and helpless, in the very midst of a pestilence that would have terrified the strongest man; but it seemed quite impossible to the brave girl that the fever should reach her. Perhaps this very confidence protected her, for while she inhaled poison with every breath, it produced no harmful effect upon her.
