This interest was protected by another provision in the constitution of the United States, by which "no person held to service or labor in one state, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labor, but shall be delivered up, on claim of the party to whom such service or labor may be due." What was this but protection to this machinery of the South? And let it be observed that a provision like this ran counter to all the tenor of legislation in the free states. It was contrary to all the notions and feelings of the people of the North to deliver a man up to any foreign authority, unless he had been guilty of some crime; and, but for such a clause in the compact, a Southern gentleman, who had lost an article of his machinery, would never recover him back from the free states. The constitution contained another clause guaranteeing protection to the same interest. It guaranteed to every state in the Union a republican form of government, protection against invasion, and, on the application of the Legislature or Executive of any state, furnished them with protection against domestic violence. Now, everybody knew that where this machinery existed the state was more liable to domestic violence than elsewhere, because that machinery sometimes exerted a self-moving power. The call for this protection had very recently been made, and it had been answered, and the power of the Union had been exerted to insure the owners of this machinery from domestic violence.
