    “It would be idle to say that we were not, from time to time, aware that a volcano slumbered fitfully beneath us. There were dark sides to the Slavery Question, for master, as for slave.”
    —Marion Harland (1830–1922)

    “We are like travellers using the cinders of a volcano to roast their eggs. Whilst we see that it always stands ready to clothe what we would say, we cannot avoid the question whether the characters are not significant of themselves.”
