Soon after Mr. Adams took his seat in Congress, the movement for the abolition of slavery was begun by a few obscure agitators. It did not at first attract much attention, but as it went on it gradually exasperated the overbearing temper of the Southern slaveholders. One fruit of this agitation was the appearance of petitions for the abolition of slavery in the House of Representatives. A few were presented by Mr. Adams without attracting much notice; but as the petitions multiplied, the Southern representatives became aroused. They assailed Mr. Adams for presenting them, and finally passed what was known as the gag rule, which prevented the reception of these petitions by the House. Against this rule Mr. Adams protested, in the midst of the loud shouts of the Southerners, as a violation of his constitutional rights. But the tyranny of slavery at that time was so complete that the rule was adopted and enforced, and the slaveholders, undertook in this way to suppress free speech in the House, just as they also undertook to prevent the transmission through the mails of any writings adverse to slavery. With the wisdom of a statesman and a man of affairs, Mr. Adams addressed himself to the one practical point of the contest. He did not enter upon a discussion of slavery or of its abolition, but turned his whole force toward the vindication of the right of petition. On every petition day he would offer, in constantly increasing numbers, petitions which came to him from all parts of the country for the abolition of slavery, in this way driving the Southern representatives almost to madness, despite their rule which prevented the reception of such documents when offered. Their hatred of Mr. Adams is something difficult to conceive, and they were burning to break him down, and, if possible, drive him from the House. On February 6, 1837, after presenting the usual petitions, Mr. Adams offered one upon which he said he should like the judgment of the Speaker as to its propriety, inasmuch as it was a petition from slaves. In a moment the House was in a tumult, and loud cries of "Expel him!" "Expel him!" rose in all directions. One resolution after another was offered looking toward his expulsion or censure, and it was not until February 9, three days later, that he was able to take the floor in his own defense. His speech was a masterpiece of argument, invective, and sarcasm. He showed, among other things, that he had not offered the petition, but had only asked the opinion of the Speaker upon it, and that the petition itself prayed that slavery should not be abolished. When he closed his speech, which was quite as savage as any made against him, and infinitely abler, no one desired to reply, and the idea of censuring him was dropped.
