"The Romance of Piracy," by E. Keble Chatterton. (The episode of David's escape in the ship Hawk is founded on an actual adventure that occurred in 1622, related in Mr. Chatterton's book. The story of the mutiny aboard The Rose of Egypt was suggested by an actual episode—described in Captain Samuel's autobiography.)

To Deane H. Uptegrove and George Mullien, the writer is indebted for advice concerning the sea episodes that appear in this book. The New York Public Library, The Newark Public Library, the East Orange Public Library, and the private library of the New York Evening Post have been helpful in giving the author access to material not easily obtainable.
