"Ragged Dick" was contributed as a serial story to the pages of the Schoolmate, a well-known juvenile magazine, during the year 1867. While in course of publication, it was received with so many evidences of favor that it has been rewritten and considerably enlarged, and is now presented to the public as the first volume of a series intended to illustrate the life and experiences of the friendless and vagrant children who are now numbered by thousands in New York and other cities.
