"I have in my hand a poem which our own beloved poet John Greenleaf Whittier wrote almost fifty years ago, in the darkest hour of the midnight which brooded over our country. You are most of you, perhaps all, familiar with it. It is addressed to Mr. Garrison. Shall I read a single stanza? I do it to illustrate a point strongly put by our brother who has just taken his seat; that is, the power of a single soul, alone, of a single soul touched with sacred fire, a soul all of whose powers are enlisted the thought, the feeling, the susceptibility, the emotion, the indomitable will, the conscience that never shrinks, and always points to duty-I say, the power which God has lodged in the human mind, enabling to do and to dare and to suffer everything, and thank God for the privilege of doing it. To show also how, when one soul is thus stirred in its innermost and to its uttermost, it is irresistible; that wherever there are souls, here and there, and thick and fast, too, not merely one, and another, and another, of the great mass, but multitudes of souls are ready to receive the truth and welcome it, to incorporate it into their thought and feeling, to live and die for it. That was the effect of Garrison upon the soul of Whittier. He here gives us his testimony. The date of this is 1833-almost fifty years ago. He says in the third stanza: "I love thee with a brother's love,/I feel my pulses thrill/To mark thy spirit soar above/The cloud of human ill./My heart hath leaped to answer thine,/And echo back thy words,/As leaps the warrior's at the shine/And flash of kindred swords!""
