After seven years I am loath to part with the saddest task ever committed to human hands! I have tracked my bleeding countrymen through the widely scattered documents of American history; I have listened to their groans, their clanking chains, and melting prayers, until the woes of a race and the agonies of centuries seem to crowd upon my soul as a bitter reality. Many pages of this history have been blistered with my tears; and, although having lived but a little more than a generation, my mind feels as if it were cycles old. The long spectral hand on the clock of American history points to the completion of the second decade since the American slave became an American citizen. How wondrous have been his strides, how marvellous his achievements! Twenty years ago we were in the midst of a great war for the extinction of slavery; in this anniversary week I complete my task, record the results of that struggle. I modestly strive to lift the Negro race to its pedestal in American history. I raise this post to indicate the progress of humanity; to instruct the present, to inform the future. I commit this work to the considerate judgment of my fellow-citizens of every race, "with malice toward none, and charity for all." GEO. W. WILLIAMS. HOFFMAN HOUSE, NEW YORK CITY, Dec. 28, 1882.
