Oliver Johnson gave his young manhood to the negro’s cause when to be an Abolitionist cost more than words. He was, in the earlier days of the movement, one of the hardest workers; both as a lecturer and writer, that the cause had. Mr. Johnson is a cogent reasoner, a deep thinker, a ready debater, an accomplished writer, and an eloquent speaker. He has at times edited the “Herald of Freedom,” “Anti-Slavery Standard,” and “Anti-Slavery Bugle;” and has at all times been one of the most uncompromising and reliable of the “Old Guard.” Henry C. Wright was also among the early adherents to the doctrine of universal and immediate emancipation, and gave the cause the best years of his life. Giles B. Stebbins, a ripe scholar, an acute thinker, earnest and able as a speaker, devoted to what he conceives to be right, was for years one of the most untiring of freedom’s advocates. Of those who occasionally volunteered their services without money and without price, few struck harder blows at the old Bastile of slavery than James N. Buffum, a man of the people, whose abilities have been appreciated and acknowledged by his election as mayor of his own city of Lynn. James Miller McKim was one of the signers of the Declaration of Sentiments, at Philadelphia, in 1833, and ever after gave his heart and his labors to the slave’s cause. For many years the leading man in the Anti-slavery Society in Pennsylvania, Mr. McKim’s labors were arduous, yet he never swerved from duty. He is a scholar, well read, and is a good speaker, only a little nervous. His round face indicates perseverance that will not falter, and integrity that will not disappoint. He always enjoyed the confidence of the Abolitionists throughout the country, and is regarded as a man of high moral character. Of the underground railroad through Pennsylvania, Mr. McKim knows more than any man except William Still. Mary Grew, for her earnest labors, untiring activity, and truly eloquent speeches, was listened to with great interest and attention wherever she spoke. A more zealous and able friend the slave never had in Pennsylvania. Lucretia Mott, the most eloquent woman that America ever produced, was a life-long Abolitionist, of the straightest kind. For years her clothing, food, and even the paper that she wrote her letters on, were the products of free labor. Thirty years ago we saw Mrs. Mott take from her pocket a little paper bag filled with sugar, and sweeten her tea. We then learned that it was her practice so to do when travelling, to be sure of having free sugar. A phrenologist would pronounce her head faultless. She has a thoughtful countenance, eyes beaming with intelligence, and a voice of much compass. Mrs. Mott speaks hesitatingly at times, when she begins her remarks, and then words flow easily, and every word has a thought. She was always a favorite with the Abolitionists, and a welcome speaker at their anniversary meetings.
