It is possible that the phrase "emit bills on the credit of the United States" might have been left in the Constitution, without any other danger than the hazards of a doubtful construction, which would have confined its meaning to the issuing of certificates of debt under the power to "borrow money." But this was not the sense in which the term "bills of credit" was generally received throughout the country, nor the sense intended to be given to it in the clause which contained the prohibition on the States. The well-understood meaning of the term had reference to paper issues, intended to circulate as currency, and bearing the public promise to pay a sum of money at a future time, whether made or not made a legal tender in payment of debts. It would have been of no avail, therefore, to have added a prohibition against making such bills a legal tender. If a power to issue them should once be seen in the Constitution, or should be suspected by the people to be there, wrapt in the power of borrowing money, the instrument would array against itself a formidable and probably a fatal opposition. It was deemed wiser, therefore, even if unforeseen emergencies might in some cases make the exercise of such a power useful, to withhold it altogether. It was accordingly stricken out, by a vote of nine States against two, and the authority of Congress was thus confined to borrowing money on the credit of the United States, which appears to have been intended to include the issuing of government notes not transferable as currency.[247]
