Prentiss Ingraham BOOKS THAT NEVER GROW OLD Alger Series Clean Adventure Stories for Boys The Most Complete List Published The following list does not contain all the books that Horatio Alger wrote, but it contains most of them, and certainly the best. Horatio Alger is to boys what Charles Dickens is to grown-ups. His work is just as popular to-day as it was years ago. The books have a quality, the value of which is beyond computation. There are legions of boys of foreign parents who are being helped along the road to true Americanism by reading these books which are so peculiarly American in tone that the reader cannot fail to absorb some of the spirit of fair play and clean living which is so characteristically American. In this list will be included certain books by Edward Stratemeyer, Oliver Optic, and other authors who wrote the Alger type of stories, which are equal in interest and wholesomeness with those written by the famous author after which this great line of books for boys is named. _ALL TITLES ALWAYS IN PRINT_ By HORATIO ALGER, Jr.
