Two distinct propositions were thus before the Convention. One of them contemplated a qualification of the revenue power, the other did not. One was to give authority to Congress to pay the revolutionary debt, both of the United States and of the States, and to fulfil all the engagements of the Confederation; the other was to declare that revenues were to be raised and taxes levied for the purpose of paying the debts and necessary expenses of the United States, limiting all revenue laws, excepting those which were to appropriate specific funds to the payment of interest on debts or loans, to a term of years. When these propositions came to be acted upon, that reported by the grand committee was modified into the declaration that "all debts contracted and engagements entered into, by or under the authority of Congress, shall be as valid against the United States, under this Constitution, as under the Confederation." The State debts were thus left out; the declaration was prefixed, as an amendment, to the clause which granted the revenue power, and was thus obviously no qualification of that power.[238] But it was thought by Mr. Sherman, that the clause for laying taxes and duties ought to have connected with it an express provision for the payment of the old debts; and he accordingly moved to add to that clause the words, "for the payment of said debts, and for the defraying the expenses that shall be incurred for the common defence and general welfare." This was regarded by the Convention as unnecessary, and was therefore not adopted.[239] But the provision reported by the committee of detail, which was intended as a qualification of the revenue power, by declaring the objects for which taxes and duties were to be levied, had not yet been acted upon, and on the 31st of August, this, with all other matters not disposed of, was referred to a new grand committee, who, on the 4th of September, introduced an amendment to the revenue clause, which made it read as follows:--"The legislature shall have power to lay and collect taxes, duties, imposts, and excises, to pay the debts, and provide for the common defence and general welfare of the United States." This amendment was unanimously adopted;[240] and when the Constitution was revised, at the close of the proceedings, the declaration which made the debts and engagements of the Confederation obligatory upon the new Congress, was separated from the context of the revenue clause, and placed by itself in the _sixth_ article.
