MR. QUINCY,--A year has nearly run since I left Boston in the discharge of public duties. During this period, amidst important events, I have been able to do something which my fellow-citizens and neighbors, speaking by your authoritative voice, are pleased to approve. I am happy in this approbation. Especially am I happy that it is conveyed by the eloquent words of one who from my childhood has been with me an object of unaffected reverence, who was the municipal head of my native city while I was a pupil at its public schools, and who was the head of the University while I was a pupil in that ancient seat. Boston, early in her history, set her face against Slavery. By a vote, entered upon her Town Records, as long ago as 1701, she called upon her Representatives “to put a period to negroes being slaves.” If I have done anything to deserve the greeting you now lavish, it is because I have striven to maintain those principles here declared, and to extend them to other places,--stretching the venerable shelter of Faneuil Hall even over distant Kansas. [_Loud applause._] You have made allusion to the suffering which I have undergone. This is not small. But it has been incurred in the performance of duty; and how little is it, Sir, compared with the suffering of fellow-citizens in Kansas! How small is it, compared with that tale of woe which is perpetually coming to us from the house of bondage! With you I hail the omens of final triumph. I ask no prophet to confirm this assurance. The future is not less secure than the past. You are pleased to quote injunctions of Washington. If ever there was occasion to bear these, not only in memory, but in heart, the time is now, when Usurpation is the order of the day, and the Constitution is set at defiance. Beyond these precepts is also his great example, which, from first to last, teaches the constant lesson of fidelity, in standing up for the liberties of our country, in undoubting faith that the good cause cannot fail. The rule of duty is the same for the lowly and the great; and, in the communication which I addressed to the Legislature of Massachusetts, accepting the trust which I now hold, I ventured to adopt the determination of Washington, and to avow his confidence. In both I hope to hold fast unto the end. [_Loud cheers._] Mr. Sumner then passed from the carriage in which he had been riding into that of Mr. Quincy and Mayor Rice. Professor Huntington also took a seat in the same carriage, which was drawn by six splendid gray horses. A body-guard of marshals mounted, and of police, formed on each side of the barouche, in order to keep the multitudes in the streets from pressing up to shake hands with Mr. Sumner. The cavalcade then proceeded onwards, amid repeated cheers of the multitudes lining the streets on both sides. In accordance with directions from his physician, Mr. Sumner acknowledged these demonstrations only by a wave of the hand.
