Notwithstanding the sturdy opposition which Mr. Webster arrayed against this system, as advocated by Mr. Clay, he became its ardent supporter when time had tested and proved its importance. Many other public functionaries also, who had assailed it in the most vindictive manner, laid down their weapons, and cordially embraced, with strong protecting arms, its salutary provisions. Even bigotry and prejudice were forced into an unwilling acknowledgement of its utility, and were soon seen placing themselves in a situation where its benign influences would fall upon them.
In 1819, the most exciting question that ever agitated the councils of the nation, came before congress for adjustment――the question of admitting Missouri as a state into the Union. It was correctly called a ‘_distracting question_,’ for it caused a political earthquake, whose quaking influences were felt from one end of the land to the other; and even now its recollection causes a sensation of terror to come over those who were the immediate witnesses of it. Its contemplation made the stout-hearted patriot, and the immovably good of all classes, to turn pale with fear, who believed, that unless it could be calmed, it would engulph in irremediable ruin the liberties of the republic. It was not the simple question of admission which convulsed the country, but the terms with which it was proposed to connect her reception into the confederacy――terms involving another question, one which furnished all the fuel which kindled the fires of the most acrimonious strife, in every section of the nation――the _question of slavery_. The question of admission divided the country into two great parties. A large and respectable portion of her representatives at Washington, desired the admission to be unconditional, while the other wished it to be subject to certain conditions, among which was the following: that ‘all children of slaves, born within the said state after the admission thereof into the union, shall be free, but may be held to service until the age of twenty-five years, and the farther introduction of slavery or involuntary servitude is prohibited, except for the punishment of crimes whereof the party shall have been duly convicted.’ With the certainty of intuition, Mr. Clay foresaw and predicted the alarming consequences which would flow from the fiery crucible of public debate, if this combustible condition was placed in it, and rang the tocsin peal of his voice in the ears of the nation. Although opposed to slavery, and declaring that if he were a citizen of Missouri, he would strenuously oppose any farther introduction of slaves into her, and provide for the emancipation of those already within her borders, still he believed we had no right to compel her to adopt our opinions, especially as she was unrepresented, and preferred leaving the subject of slavery to be settled by her alone.
