The union of these States is based on what has been called the slavery compromise; and the Union would have never taken place, had not the right to hold slave property been secured to the slave states, by a provision in the Federal Constitution. Had not the free states relinquished all right to interfere with slavery in the slave states, no union of the slave and free states could ever have taken place. The right to hold slave property, and to manage, control, and dispose of that property in their own way, and at their own discretion, was secured to the slave states by a solemn contract between the slave and non-slaveholding states, and that contract binds every individual in this nation, North and South. Slave property then, is held under the protection of the supreme law of the nation, and any citizen invading the rights of the South, is guilty of a civil trespass. Hence, all interference with slavery by northern men, is a violation of the spirit, if not of the letter of that constitutional compact, which binds these states together. Any attempt by northern men, either direct or indirect, to dispossess the South of her slave property, or in any way to endanger or injuriously to affect their interests therein, is a violation of the supreme law of the nation. It is an act of bad faith--of gross injustice, and none but bigoted corrupt fanatics, and low political demagogues, would be guilty of so base an act.
