But the gentleman does not rest himself on this ground alone. He does not embark his whole treasure in a single bottom. Granting that the United States are not destitute of capacity to acquire territory, he denies that this acquisition has been made in a regular way--Congress, says he, alone is competent to such an act. In this transaction he scents at a distance Executive encroachment, and we are called upon to assert our rights, and to repel it. If any usurpation of the privileges of Congress, or of this House, be made to appear, I pledge myself to that gentleman to join him in resisting it. But let us inquire into the fact. No gentleman will deny the right of the President to initiate business here, by message, recommending particular subjects to our attention. If the Government of the United States possess the constitutional power to acquire territory from foreign States, the Executive, as the organ by which we communicate with such States, must be the prime agent in negotiating such an acquisition. Conceding, then, that the power of confirming this act, and annexing to the United States the territory thus acquired, ultimately rests with Congress, where has been the invasion of the privileges of that body? Does not the President of the United States submit this subject to Congress for their sanction? Does he not recognize the principle, which I trust we will never give up, that no treaty is binding until we pass the laws for executing it--that the powers conferred by the constitution on Congress cannot be modified, or abridged, by any treaty whatever--that the subjects of which they have cognizance cannot be taken, in any way, out of their jurisdiction? In this procedure nothing is to be seen but a respect, on the part of the Executive, for our rights; a recognition of a discretion on our part to accord or refuse our sanction. Where, then, is the violation of our rights? As to the initiative, in a matter like this, it necessarily devolved on the Executive. Mr. R. said, that he would not dilate upon the importance of the navigation of the Mississippi, which had been the theme of every tongue, which we now possessed unfettered by the equal claim of the nation holding the west bank, a fruitful source of quarrel; but he would call the attention of the committee to a report which had been made at the last session and to which publicity had lately been given.
