We have been told that non-intervention on the part of Congress with slavery in the Territories is the true policy. Very well. I most cheerfully admit that Congress has no right to pass any law to establish, impair or abolish slavery in the Territories. Let this principle of non-intervention be extended to the Territorial legislatures, and let it be declared that they in like manner have no power to establish, impair or destroy slavery, and then the controversy is in effect ended. This is all that is required at present, and I verily believe all that will ever be required. Hands off by Congress and hands off by the Territorial legislature. [Loud applause.] With the Supreme Court of the United States I hold that neither Congress nor the Territorial legislature has any power to establish, impair or abolish slavery in the Territories. But if, in the face of this positive prohibition, the Territorial legislature should exercise the power of intervening, then this would be a mere transfer of the Wilmot proviso and the Buffalo platform from Congress, to be carried into execution in the Territories to the destruction of all property in slaves. [Renewed applause.] An attempt of this kind, if made in Congress, would be resisted by able men on the floor of both houses, and probably defeated. Not so in a remote Territory. To every new Territory there will be a rush of free-soilers from the Northern States. They would elect the first Territorial legislature before the people of the South could arrive with their property, and this legislature would probably settle forever the question of slavery according to their own will. And shall we for the sake of squatter sovereignty, which, from its nature, can only continue during the brief period of Territorial existence, incur the risk of dividing the great Democratic party of the country into two sectional parties, the one North and the other South? Shall this great party which has governed the country in peace and war, which has raised it from humble beginnings to be one of the most prosperous and powerful nations in the world—shall this party be broken up for such a cause? That is the question. The numerous, powerful, pious and respectable Methodist Church has been thus divided. The division was a severe shock to the Union. A similar division of the great Democratic party, should it continue, would rend asunder one of the most powerful links which binds the Union together.
