Miss Mischief Maker.

Little Sallie O'Brien, who sells newspapers on the city streets, is adopted by Bridget Cassidy, the landlady, when her mother dies. Mrs. Cassidy treats the child cruelly, but soon the wealthy James Wilson befriends Sallie and takes her into his home. Sallie is befriended by Wilson's son Richard, but his daughter Marjorie dislikes the impish little girl.
