It is usual on occasions of this kind, not only to set forth, as I have in some measure done, what has been gained by the abolition of slavery, but also to speak of the causes and instrumentalities which contributed to this grand result. If this were my first appearance before you on similar anniversaries, I should feel it entirely proper to do so now; but having discharged this duty faithfully and fully in several former addresses, there is no special reason for a repetition of it in this instance. In one of those addresses I specially endeavored to trace, and did trace with more or less success, the history of the earliest utterances of anti-slavery sentiments in this country and in England. I described the rise, progress, and final triumph of the abolition movement in both countries. I have in no case omitted to do justice to the noble band of men and women who espoused the cause of the slave in the early days of its weakness, and when to do so was to make themselves of no reputation and subjects of the vilest abuse. I have held up their example of virtuous self-sacrifice to the admiration and imitation of all who would serve the human family in its march from barbarism to a higher state of civilization. In my judgment there never was a band of reformers more unselfish, more consistent with their principles, more ardent in their devotion to any cause than were these early anti-slavery men and women of this country. The charge is sometimes made that the colored people are ungrateful to their benefactors. In my judgment no charge could be more unjust. In whatever else they have failed, they have ever shown a laudable sense of gratitude. The names of William Lloyd Garrison, Wendell Phillips, John P. Hale, Charles Sumner, Gerrit Smith, Abraham Lincoln, Ulysses S. Grant, and a host of others are never pronounced by us but with sentiments of high appreciation and sincere gratitude.
