“The center brick house belonged to one of the innumerable cousins of George Washington; it is haunted (to the delight of the girls, who eat there) by a wailing woman who went crazy some hundred and twenty years ago and was chained in the attic. She wails quite audibly. An old bell in back summons the girls to classes; with what they consider hideous appropriateness, it was a slave bell.” Fortune Classic, 1931
