Of one thing I am confident, that if they have the distrust of us which some gentlemen have this day expressed of them, the country will not be delivered to the agents of our Government should this bill be rejected. The gentleman from Connecticut (Mr. TRACY) muse consider the grant of power to the Legislature as a limitation of the treaty-making power, for he says, “that the power to admit new States and to make citizens is given to Congress, and not to the treaty-making power;” therefore an engagement in a treaty to do either of these things is unconstitutional. I cannot help expressing my surprise at that gentleman’s giving that opinion, and I think myself justifiable in saying, that if it is now his opinion, it was not always so. The contrary opinion is the only justification of that gentleman’s approbation of the British treaty, and of his vote for carrying it into effect. By that treaty a great number of persons had a right to become American citizens immediately; not only without a law, but contrary to an existing law. And by that treaty many of the powers specially given to Congress were exercised by the treaty-making power. It is for gentlemen who supported that treaty, to reconcile the construction given by them to the constitution in its application to that instrument, with their exposition of it at this time. If the third article of the treaty is an engagement to incorporate the Territory of Louisiana into the Union of the United States, and to make it a State, it cannot be considered as an unconstitutional exercise of the treaty-making power; for it will not be asserted by any rational man that the territory is incorporated as a State by the treaty itself, when it is expressly declared that “the inhabitants shall be incorporated in the Union of the United States, and admitted as soon as possible, according to the principles of the Federal Constitution.” Evidently referring the question of incorporation, in whatever character it was to take place, to the competent authority; and leaving to that authority to do it, at such time, and in such manner, as they may think proper. If, as some gentlemen suppose, Congress possess this power, they are free to exercise it in the manner that they may think most conducive to the public good. If it can only be done by an amendment to the constitution, it is a matter of discretion with the States whether they will do it or not; for it cannot be done “according to the principles of the Federal Constitution,” if the Congress or the States are deprived of that discretion, which is given to the first, and secured to the last, by the constitution. In the third section of the fourth article of the constitution it is said, “New States may be admitted by the Congress into this Union.” If Congress have the power, it is derived from this source; for there are no other words in the constitution that can, by any construction that can be given to them, be considered as conveying this power.
