"She had been told Lord Shaftesbury was one of the great good men of England; and she resolved to call upon him in person, and entreat an interview. His lordship immediately granted her request, listened patiently to her history, and directly gave her a letter of introduction to his lawyer. "It may perhaps be considered a providential concurrence that Mrs. Harriet Beecher Stowe was in London this same time with Miss Greenfield. We notice in her 'Sunny Memories,' under the date of May 6, the following remarks: 'A good many calls this morning. Among others came Miss Greenfield, the (so-called) "Black Swan." She appears to be a gentle, amiable, and interesting young person. She has a most astonishing voice. C. sat down to the piano, and played while she sang. Her voice runs through a compass of three octaves and a fourth. This is four notes more than Malibran's. She sings a most magnificent tenor, with such a breadth and volume of sound, that, with your back turned, you could not imagine it to be a woman. While she was there, Mrs. S.C. Hall, of the "Irish Sketches," was announced. I told her of Miss Greenfield; and she took great interest in her, and requested her to sing something for her. C. played the accompaniment, and she sang "Old Folks at Home," first in a soprano voice, and then in a tenor, or baritone. Mrs. Hall was amazed and delighted, and entered at once into her cause. She said she would call with me, and present her to Sir George Smart, who is at the head of the Queen's musical establishment, and, of course, the acknowledged leader of London musical judgment. "'In the course of the day I had a note from Mrs. Hall, saying, that, as Sir George Smart was about leaving town, she had not waited for me, but had taken Miss Greenfield to him herself. She writes that he was really astonished and charmed at the wonderful weight, compass, and power of her voice. He was also as well pleased with the mind in her singing, and her quickness in doing and catching all that he told her. Should she have a public opportunity to perform, he offered to hear her rehearse beforehand. Mrs. Hall says, "This is a great deal for him, whose hours are all marked with gold."'
