They have chosen to trust themselves, first, to the plain words of the instrument, and to such construction as the government itself, in doubtful cases, should put on its own powers, under its oaths of office, and subject to its responsibility to them; just as the people of a State trust their own State governments with a similar power. Secondly, they have reposed their trust in the efficacy of frequent elections, and in their own power to remove their own servants and agents whenever they see cause. Thirdly, they have reposed trust in the judicial power, which, in order that it might be trustworthy, they have made as respectable, as disinterested, and as independent as was practicable. Fourthly, they have seen fit to rely, in case of necessity or high expediency, on their known and admitted power to alter or amend the Constitution peaceably and quietly, whenever experience shall point out defects or imperfections. And, finally, the people of the United States have at no time, in no way, directly or indirectly, authorized any State legislature to construe or interpret their high instrument of government; much less to interfere by their own power to arrest its course and operation. I have thus stated the reasons of my dissent to the doctrines which have been advanced and maintained. I am conscious of having detained you and the Senate much too long. I was drawn into the debate with no previous deliberation, such as is suited to the discussion of so grave and important a subject. But it is a subject of which my heart is full, and I have not been willing to suppress the utterance of its spontaneous sentiments. I cannot, even now, persuade myself to relinquish it, without expressing once more my deep conviction that, since it respects nothing less than the union of the states, it is of most vital and essential importance to public happiness. I profess, sir, in my career hitherto to have kept steadily in view the prosperity and honor of the whole country, and the preservation of our Federal Union. It is to that Union we owe our safety at home, and our consideration and dignity abroad. It is to that Union that we are chiefly indebted for whatever makes us most proud of our country. That Union we reached only by the discipline of our virtues in the severe school of adversity. It had its origin in the necessities of disordered finance, prostrate commerce, and ruined credit. Under its benign influences, these great interests immediately awoke as from the dead, and sprang forth with newness of life. Every year of its duration has teemed with fresh proofs of its utility and its blessings; and although our territory has stretched out wider and wider, and our population spread farther and farther, they have not outrun its protection or its benefits. It has been to us all a copious fountain of national, social, and personal happiness.
