The doctrine of the "implied powers" rested upon the theory that unless they were directly prohibited by the Constitution, all powers were granted to the government by implication which were found necessary and proper for carrying out the powers specifically granted. Jefferson came to believe, if he did not believe at the outset, that the government was one of delegated powers which were strictly limited to those enumerated in the Constitution. The doctrine of Hamilton, from this point of view, was revolutionary. It meant the conversion of a government holding limited delegations of power from the people and the states into a government having supreme power, capable of taking an infinite variety of measures whenever Congress, in the exercise of its discretion, believed that such measures would contribute to the well-being of the Union. The state governments, coming closer to the people than the federal government, were most directly threatened by this assumption of power, and it was as the champions of state rights as well as democratic ideas that Jefferson and his friends took their ground as the advocates of the strict construction of the Constitution.
It is not surprising, therefore, that the proposal to create the Bank of the United States called forth in Congress prolonged and heated debates. But the policy of Hamilton had been so far successful in restoring the public credit that he carried the project for the national bank through both houses, and it was laid before the President for his approval. Washington had watched with interest the struggle in the two houses, and was somewhat impressed by the weight of the argument against the constitutional power of Congress to establish the bank. The cabinet was divided. Jefferson and Randolph were against the constitutionality of the bill. Hamilton and Knox were in favor of it. Washington asked each of them to give him in writing the reasons for his opinion. He weighed them carefully and then affixed his signature to the bill (February 25, 1791). The new project realized all the benefits which Hamilton expected. Washington, in his tour of the Southern States in the spring of 1791, found the sentiment for union strengthening and the country recovering from the prostration of the era of bad money and political uncertainty which had followed the Revolution. He declared in a letter written after his return:
"Our public credit stands on that ground, which, three years ago, it would have been madness to have foretold. The astonishing rapidity with which the newly instituted bank was filled, gives an unexampled proof of the resources of our countrymen and their confidence in public measures. On the first day of opening the subscription, the whole number of shares (twenty thousand) were taken up in one hour, and application made for upwards of four thousand shares more than were granted by the institution, besides many others that were coming in from various quarters."
How much was likely to be done by a national bank to bind together the commercial interests of different sections of the country can hardly be appreciated to-day. At that time there were only four banks in the country; none of these was ten years old, and their combined capital was only $1,950,000. The Bank of the United States was authorized to establish offices of discount and deposit in all the states and to distribute parts of its capital among eight branches in the chief cities of the country. It was the drafts of these branches upon each other, and their means for reducing to a uniform and reasonable rate the cost of transferring funds, which contributed to knit all parts of the country together in commercial matters and so strengthened the bond of political union. The bank did not make regular reports to the Treasury Department, but its success is indicated by a special report communicated to Congress by Secretary Gallatin (January 24, 1811), which showed resources of $24,183,046. The average annual dividends paid upon the stock up to March, 1809, were over eight per cent.
So invaluable were the operations of the Bank of the United States to the public treasury that Jefferson himself when President came to its support. His support was perhaps never very hearty, and was due to Albert Gallatin, his Secretary of the Treasury, whose foresight and ability give him a rank next to Hamilton among the able men who have presided over the national finances. Gallatin made a strong report in 1809, recommending that the charter of the bank be renewed upon its expiration in 1811, with an increase of capital and wider powers. A new charter was voted in the House, but the bill was not acted on in the Senate, and before the next session the opposition of the state bankers had rallied sufficient strength to defeat the recharter. The second United States Bank was authorized in 1816, under the administration of Madison and with his approval, but its career was terminated in 1836, as the result of the political hostility of President Jackson.
It was not until after the grant of this second charter that the question of the power of Congress to establish a bank came directly before the Supreme Court in 1819. At the head of this court sat John Marshall, who next to Hamilton, perhaps, did more than any other man to strengthen and extend the powers of the general government. The jealousy of the state banks had led the State of Maryland to impose a discriminating tax on the Bank of the United States. If the right to levy such a tax had been admitted, the Bank would have been completely at the mercy of the states, and one of the chief purposes of its creation would have been defeated. In order to sustain the right of the bank to exemption from taxation, it was necessary to prove that it was a constitutional instrument of federal power. Hence the question of the power of Congress to create such a corporation came directly before the court.
Hamilton found the power to create a bank partly in the preamble to the Constitution, which declares that the people of the United States have adopted it in order to "promote the general welfare," but more particularly in that concluding phrase of the clause defining the powers of Congress, which declares that that body shall have authority "to make all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this Constitution in the government of the United States or in any department or officer thereof." Marshall, in the series of great decisions by which he strengthened the power of the Union, often made use of these provisions to justify his reasoning. In one of the most famous of these decisions (McCulloch vs. Maryland), he sustained the constitutionality of the bank as an instrument of federal power and denied the right of the states to levy upon its property. He declared that the power to tax involved the power to destroy, and that if the federal government had not the power to withdraw its creations from discriminating legislation by the states, the latter might tax the mail or the mints, the papers of the custom-houses, or the forms of judicial process.
The view of Hamilton regarding the power of the federal government to create a bank was thus sustained in emphatic terms by the highest court in the land. It was partly his policy in providing for the bank and demonstrating its usefulness, with his other measures to develop the powers of the central government, which made possible the decisions of Marshall. If the question of the right to incorporate a bank could have been brought before the court at the beginning, before the institution had proved its value, and if men like Jefferson and Madison had been upon the bench, there is at least room for doubt whether a decision would have been rendered in favor of a power which is not granted directly to the government by the Constitution. But by the resolute executive policy of Hamilton and the broad judicial constructions of Marshall, the functions of the new government were extended to all those great objects necessary to create a vigorous and united nation.
The many other measures of Hamilton were directed by the same singleness of purpose to strengthen the hands of the government and consolidate the Union. The report on the mint followed the previous reports of Jefferson in recommending the adoption of the dollar as the unit of value. Hamilton observed that "upon the whole, it seems to be most advisable, as has been observed, not to attach the unit exclusively to either of the metals; because this cannot be done effectually, without destroying the office and character of one of them as money, and reducing it to the situation of a mere merchandise." He believed, however, that care should be taken to regulate the proportion between the metals with an eye to their average commercial value. He pointed out the danger of undervaluing either metal, and the inevitable result, in case of a difference of ratio in two countries, "if other things were equal, that the greatest part of the gold would be collected in one, and the greatest part of the silver in the other."
