On one occasion the Broadway Tabernacle, at that time located on Broadway near Duane Street, was opened for a mass meeting. Mr. Beecher was advertised to speak, and the house was packed. He was listened to with closest attention and deepest interest, but the climax came when turning round he lifted a chain that had been taken from a slave in the South, held it for a moment high above his head, then dashed it to the floor, placed his foot upon it and said: "In this way we propose to deal with the slave power in the South." The effect upon the audience was thrilling and the applause fairly rocked the building. Another scene, which none who witnessed it could ever forget, was in Plymouth Church. It was Sabbath morning, and as usual every seat and all the available standing room was filled. After the sermon Mr. Beecher said that he had a matter which he wished to present to the congregation. No one had the least idea as to what he was going to do, and the people waited in profound silence. He then said, "Sarah, come up here." As the audience looked, a little mulatto girl arose in the body of the church, ran up the pulpit steps and took Mr. Beecher's hand. Turning to the assembled multitude he said: "This little girl is a slave, and I have promised her owner $1200, his price for her, or she will be returned to slavery. Pass the basket." The ushers found their way through the vast audience. Although the church seated only a little more than two thousand, there must have been nearly three thousand present, and soon the collection was made. It appeared that the sum total was not far from fifteen hundred dollars. Many gave jewelry, diamonds, watches and chains. Her freedom was announced amid thunders of applause. This was not the only instance of a similar nature. Mr. Beecher was frequently condemned for even in form acknowledging the right of a slave owner to any remuneration for a slave, but if he thought a thing right to do, he did it without the least regard to what other people might say. There was probably no one question at the time about which there were more intensely opposing opinions, than this one of the return of slaves. Congress had passed the fugitive slave law, and all lawyers and students of the Constitution affirmed not merely its legality, but its justice, at least its technical justice. To a large number, however, the fact that it was legal made no difference so long as they were convinced that it was morally wrong. Among these was Mr. Beecher, and he had the cordial support of the people. One result was the formation all through the North of a system, known as the Underground Railroad, by which slaves escaping from the South were helped on their way until they could reach Canada, when they were free. It was no secret that some of the men in Plymouth Church knew a good deal about this railroad, and were deeply interested in helping men, women and girls to escape from bondage.
