It was the writing of "Uncle Tom's Cabin" that brought world-wide fame to this unusual mother. The family had moved from Cincinnati to Brunswick, Maine, where Professor Stowe had accepted a position in the faculty of Bowdoin College. There were six children now and the father's income was meager. In order to help meet the family expenses, Mrs. Stowe began to write articles for a magazine known as the "National Era." She labored under difficulties. "If I sit by the open fire in the parlor," she wrote, "my back freezes, if I sit in my bedroom and try to write my head and my feet are cold.... I can earn four hundred dollars a year by writing, but I don't want to feel that I must, and when weary with teaching the children, and tending the baby, and buying provisions, and mending dresses, and darning stockings, I sit down and write a piece for some paper." The passage of the Fugitive Slave Act aroused the deepest feeling among Abolitionists in the North. While living in Cincinnati her family had aided the so-called "underground railway," by which runaway slaves were helped in their efforts to reach the Canadian boundary. Now Mrs. Stowe's spirit burned within her. "I wish," she writes at this period, "some Martin Luther would arise to set this community right." It was then she conceived the idea of writing "Uncle Tom's Cabin." In the month of February, 1851, while attending communion service in the college church at Brunswick, the scene of the death of Uncle Tom passed before her mind like the unfolding of a vision. When she returned home she immediately wrote down the mental picture she had seen. Then she gathered her children around her and read what she had written. Two of them broke into violent weeping, the first of many thousands who have wept over "Uncle Tom's Cabin." The first chapter was not completed until the following April, and on June 5 it began to appear in serial form in the "National Era." She had intended to write a short tale of a few chapters, but as her task progressed the conviction grew on her that she had been intrusted with a holy mission. Afterwards she said: "I could not control the story; it wrote itself." At another time she remarked: "The Lord himself wrote it, and I was but the humblest of instruments in His hand. To Him alone should be given all the praise."
