Through her years of teaching Miss Swain showed the same conscientious spirit that was evidenced in her child and school life. "Have I done all I ought? Have I been as helpful to my pupils as I might be?" she often asked herself. For a time she taught a class in Sunday school, and her boys were impressed by her consistent life. Later, one of them said, "We noticed that you always went to prayer meeting so we thought we would go and see what was in it." This class was a joy to her and her pleasure was great when one and another gave himself to the Lord for service.
"Miss Swain was ready in season and out of season," said one of her friends. "One Sunday evening when a company of us were together having a sing, she turned to a young man near her and bluntly asked, 'Why are you not a Christian?' Taken by surprise, the young man had no answer ready and they both went on singing." The Rev. Mr. Hibbard was pastor of the Methodist Church in Canandaigua and Miss Swain and her friend very much enjoyed an occasional visit to the parsonage, where they were always warmly welcomed.
