Before the new President was inaugurated, in the winter of 1848-49, the struggle began in Congress, which led to the delivery of the 7th of March speech by Mr. Webster in the following year. At this point, therefore, it becomes necessary to turn back and review briefly and rapidly Mr. Webster's course in regard to the question of slavery.
His first important utterance on this momentous question was in 1819, when the land was distracted with the conflict which had suddenly arisen over the admission of Missouri. Massachusetts was strongly in favor of the exclusion of slavery from the new States, and utterly averse to any compromise. A meeting was held in the state-house at Boston, and a committee was appointed to draft a memorial to Congress, on the subject of the prohibition of slavery in the territories. This memorial,--which was afterwards adopted,--was drawn by Mr. Webster, as chairman of the committee. It set forth, first, the belief of its signers that Congress had the constitutional power "to make such a prohibition a condition on the admission of a new State into the Union, and that it is just and proper that they should exercise that power." Then came an argument on the constitutional question, and then the reasons for the exercise of the power as a general policy. The first point was that it would prevent further inequality of representation, such as existed under the Constitution in the old States, but which could not be increased without danger. The next argument went straight to the merits of the question, as involved in slavery as a system. After pointing out the value of the ordinance of 1787 to the Northwest, the memorial continued:--
"We appeal to the justice and the wisdom of the national councils to prevent the further progress of a great and serious evil. We appeal to those who look forward to the remote consequences of their measures, and who cannot balance a temporary or trifling convenience, if there were such, against a permanent growing and desolating evil.
"... The Missouri territory is a new country. If its extensive and fertile fields shall be opened as a market for slaves, the government will seem to become a party to a traffic, which in so many acts, through so many years, it has denounced as impolitic, unchristian, and inhuman.... The laws of the United States have denounced heavy penalties against the traffic in slaves, because such traffic is deemed unjust and inhuman. We appeal to the spirit of these laws; we appeal to this justice and humanity; we ask whether they ought not to operate, on the present occasion, with all their force? We have a strong feeling of the injustice of any toleration of slavery. Circumstances have entailed it on a portion of our community, which cannot be immediately relieved from it without consequences more injurious than the suffering of the evil. But to permit it in a new country, where yet no habits are formed which render it indispensable, what is it but to encourage that rapacity and fraud and violence against which we have so long pointed the denunciation of our penal code? What is it but to tarnish the proud fame of the country? What is it but to render questionable all its professions of regard for the rights of humanity and the liberties of mankind."
