Miss Mary Emerson is here,—the youngest person in Concord, though about eighty,—and the most apprehensive of a genuine thought; earnest to know of your inner life; most stimulating society; and exceedly witty withal. She says they called her old when she was young, and she has never grown any older. I wish you could see her.
