What irrepealable laws? One or the other of those which he had stated. One was the Texas compact; the other, the law of nature and physical geography; and he contended that one or the other fixed the character of the whole American continent for freedom or for slavery. He never alluded to the Missouri compromise, unless it was by the allusion to the Wilmot proviso in the Oregon bill, and therein said it was a useless and, in that connection, senseless thing. Why was it a useless and senseless thing? Because it was reenacting the law of God; because slavery had already been prohibited by physical geography. Sir, that was the meaning of Mr. Webster's speech. * * * Mr. President, I have occupied a good deal of time in exposing the cant of these gentlemen about the sanctity of the Missouri compromise, and the dishonor attached to the violation of plighted faith. I have exposed these matters in order to show that the object of these men is to withdraw from public attention the real principle involved in the bill. They well know that the abrogation of the Missouri compromise is the incident and not the principle of the bill. They well understand that the report of the committee and the bill propose to establish the principle in all Territorial organizations, that the question of slavery shall be referred to the people to regulate for themselves, and that such legislation should be had as was necessary to remove all legal obstructions to the free exercise of this right by the people. The eighth section of the Missouri act standing in the way of this great principle must be rendered inoperative and void, whether expressly repealed or not, in order to give the people the power of regulating their own domestic institutions in their own way, subject only to the Constitution. Now, sir, if these gentlemen have entire confidence in the correctness of their own position, why do they not meet the issue boldly and fairly, and controvert the soundness of this great principle of popular sovereignty in obedience to the Constitution? They know full well that this was the principle upon which the colonies separated from the crown of Great Britain, the principle upon which the battles of the Revolution were fought, and the principle upon which our republican system was founded. They cannot be ignorant of the fact that the Revolution grew out of the assertion of the right on the part of the imperial Government to interfere with the internal affairs and domestic concerns of the colonies. * * *
