In reflecting, for the short time during which the subject had been before him, he had not been able to pursue it in all its bearings, nor to solve all the difficulties it presented. He had first asked himself where was to be found the constitutional power of the Government to incorporate the territory, with the inhabitants thereof, in the Union of the United States, with the privileges of citizens of the United States--is there any such power? And if there is, where is it lodged? In giving his opinion on the constitutional right of making treaties, he would say that it was vested in the President and Senate, and that a treaty made by them on a subject constitutionally in their treaty-making power, was valid without the assent of this House. This House had, to be sure, the physical power of refusing the necessary means to carry treaties into effect; but this power was essentially different from that conferred by the constitution. But if the treaty-making power should be exceeded, if it should be undertaken to make it operate upon subjects not constitutionally vested, he had a right to say that it was his duty not to carry it into effect. Even should its provisions be highly beneficial, it was no less their constitutional duty to resist it. He would not undertake to say that his mind was perfectly fixed, but he entertained doubts--serious doubts; and he hoped gentlemen would candidly give them answers. Mr. RANDOLPH rose for the purpose of satisfying, so far as was in his power, the doubts expressed by the gentleman from New York (Mr. G. GRISWOLD). He had listened with great pleasure to the candid exposition which the gentleman had given of his objections, and from the temper which he had manifested, Mr. R. relied on being able to satisfy some of his scruples on this subject. The objections which have been urged to the motion before the committee, resolved themselves into arguments against the constitutionality, and arguments against the expediency of the treaty proposed to be carried into effect. As it would be needless to repel objections of this last kind, unless those of the first description could be satisfactorily answered, he should first reply to the observations which had been made on the constitutional doctrine.
