Herman Melville’s annotation to his copy of Nathaniel Hawthorne’s ‘Mosses from an Old Manse’
A piece of paper bearing a specimen of brightly multicolored sea moss is attached with sealing wax to the front pastedown. Melville wrote on that piece of paper in ink (apparently after it had been affixed to the book): “This moss was gathered in Salem, and therefore I place it here for a frontispiece. P.S. It may be objected that this is sea-moss; ‒ but then, it only went to sea – like many young mortals – in its youth, and to my certain knowledge has been ashore ever since.”
