Sargent, Charles Sprague, Garden and Forest, Volume 7, Garden and Forest Publishing Company, 1894, page 7, OCLC43291639, accessed 10 March 2013, Quote: "He rarely went out, except to the store of his publishers under the Astor House; he never went to the theatre, or, indeed, to any place of amusement. He took no recreation of any kind so far as I could learn. He did not appear to visit anywhere, nor did he appear to have any acquaintances. His heart was wholly in his book; it was his joy by day and his dream by night. His stay and life in the city during its incubation was his great trial. He pined for the prairies and the free open air of the wilderness. New York to him was a prison, and his hotel a cage."
Horgan, Paul, Of America East and West: Selections from the Writings of Paul Horgan, Macmillan, 1 July 1985. Quote: "He unfortunately became in love—desperately so—and what was more remarkable for a man of his intellect, with a little girl (13 years old) without any special beauty or merit—and still less talent and intelligence."
