Landmarks, unless they loom large in landscapes often visited, tend to become weed-grown tombstones over the forgotten dead, noticed only by accident.
Even the sense of landmark has been obliterated. Rebecca Harding Davis is a name known today only to a handful of American Studies people and literary historians. Few have read any of her work; fewer still teach any of it.
Myriads of human beings--those who did the necessary industrial work in the last century--lived and died and little remains from which to reconstruct their perished (vanished) lives. About them as about so much else, literature was largely silent, and the charge can be levied: Nowhere am I in it.
"No picture, poem, statement, passing them to the future
Unlimn'd, they disappear."
To those of us, descendants of their class, hungry for any rendering of what our vanished people were like, of how they lived, Rebecca Harding Davis's Life in the Iron Mills is immeasurably valuable. Details, questions, Vision, found nowhere else--dignified into literature.
