Little Susy's Six Birthdays by Elizabeth Prentiss.

In the early part of this year [1853] Mrs. Prentiss wrote Little Susy's Six Birthdays, the book that has given so much delight to tens of thousands of little children, wherever the English tongue is spoken. Like most of her books, it was an inspiration and was composed with the utmost rapidity. She read the different chapters, as they were written, to her husband, child and brother, who all with one voice expressed their admiration. In about ten days the work was finished. The manuscript was in a clear, delicate hand and without an erasure. Upon its publication it was at once recognized as a production of real genius, inimitable its kind, and neither the popular verdict nor the verdict of the children as to its merits has ever changed.—The Life and Letters of Elizabeth Prentiss (1882).
