I will quote also one of the speeches which he made near the close of his life, at a time when he was so far wasted by disease that it was necessary for him to ask the Senator from Virginia, who sits before me [Mr. Mason], to read the speech which his tameless spirit impelled him to compose, but which he was physically unable to deliver; and once again he came to the Senate chamber, when standing yet more nearly on the confines of death; he rose, his heart failing in its functions, his voice faltered, but his will was so strong that he could not realize that the icy hand was upon him, and he erroneously thought he was oppressed by the weight of his overcoat. True to his devotion to the principles he had always advocated, clinging, to the last hour of his life, to the duty to maintain the rights of his constituents, still he was here, and his honored, though feeble, voice was raised for the maintenance of the great principle to which his life had been devoted. From the speech I read as follows: "The plan of the administration can not save the Union, because it can have no effect whatever towards satisfying the States composing the Southern section of the Union, that they can, consistently with safety and honor, remain in the Union. It is, in fact, but a modification of the Wilmot proviso. It proposes to effect the same object--to exclude the South from all territory acquired by the Mexican treaty. It is well known that the South is united against the Wilmot proviso, and has committed itself, by solemn resolutions, to resist should it be adopted. Its opposition _is not to the name_, but that which it _proposes to effect_. That, the Southern States hold to be unconstitutional, unjust, inconsistent with their equality as members of the common Union, and calculated to destroy irretrievably the equilibrium between the two sections. These objections equally apply to what, for brevity, I will call the executive proviso. There is no difference between it and the Wilmot, except in the mode of effecting the object; and in that respect, I must say that the latter is much the least objectionable. It goes to its object openly, boldly, and distinctly. It claims for Congress unlimited power over the Territories, and proposes to assert it over the territories acquired from Mexico by a positive prohibition of slavery. Not so the executive proviso. It takes an indirect course, and, in order to elude the Wilmot proviso, and thereby avoid encountering the united and determined resistance of the South, it denies, by implication, the authority of Congress to legislate for the Territories, and claims the right as belonging exclusively to the inhabitants of the Territories. But to effect the object of excluding the South, it takes care, in the meantime, to let in immigrants freely from the Northern
