THE invitation to write this life was readily accepted, partly because I hoped it would in some degree reduce the color-prejudice, with other prejudices also, and partly because I have always felt an admiration for Mr. Douglass, which has increased as I have come to know him thoroughly. His consent was cordially given in a letter, where he says: "If you can say anything of me that the public does not already know, by all means tell it. I am sure you cannot say anything of me which will not be pretty strongly colored, but go ahead." Shortly before departing to Hayti he was kind enough to answer many questions which I put to him in his house, on Cedar Hill, and to relate anecdotes which will be new to my readers. He also lent me ten of his unpublished lectures, and so many other manuscripts and rare pamphlets, that I have been able not only to mention but to quote more than a hundred works by an author not admitted to a place among the forty-six thousand writers of English enrolled by Allibone. The list of published speeches, etc., in the Appendix has been made as complete as possible by inquiry in various directions. Much valuable information was obtained from Mr. Frederick Douglass, Jr., whose scrap-books gave me abundance of material about the later years of his father's life. By far the most difficult part of my work has been that relating to the decade just before the war; and here I was greatly aided and encouraged by the letters of reminiscences contributed by Miss Sallie Holley, Mrs. Lucy N. Colman, and another lady who knew Mr. Douglass in Rochester. For these and other extraordinary opportunities I am very grateful.
