The whole system was resisted from its inception by many of our ablest statesmen, some of whom doubted its constitutionality and its expediency, while others believed it was in all its branches a flagrant and dangerous infraction of the Constitution. That a national bank, a protective tariff--levied not to raise the revenue needed, but for protection merely--internal improvements, and the distribution of the proceeds of the sale of the public lands are measures without the warrant of the Constitution would, upon the maturest consideration, seem to be clear. It is remarkable that no one of these measures, involving such momentous consequences, is authorized by any express grant of power in the Constitution. No one of them is "incident to, as being necessary and proper for the execution of, the specific powers" granted by the Constitution. The authority under which it has been attempted to justify each of them is derived from inferences and constructions of the Constitution which its letter and its whole object and design do not warrant. Is it to be conceived that such immense powers would have been left by the framers of the Constitution to mere inferences and doubtful constructions? Had it been intended to confer them on the Federal Government, it is but reasonable to conclude that it would have been done by plain and unequivocal grants. This was not done; but the whole structure of which the "American system" consisted was reared on no other or better foundation than forced implications and inferences of power, which its authors assumed might be deduced by construction from the Constitution. But it has been urged that the national bank, which constituted so essential a branch of this combined system of measures, was not a new measure, and that its constitutionality had been previously sanctioned, because a bank had been chartered in 1791 and had received the official signature of President Washington. A few facts will show the just weight to which this precedent should be entitled as bearing upon the question of constitutionality.
