Guided by the views expressed in the dissenting opinion in the former case, it must be taken for granted that the legal tender feature in the acts in question was placed emphatically, by those who enacted the provision, upon the necessity of the measure to the further borrowing of money and maintaining the army and navy, and such appears to be the principal ground assumed in the present opinion of the court. Enough also appears in some of the interrogative sentences of the dissenting opinion to show that the learned justice who delivered it intended to place the dissent very largely upon the same ground.

Nothing need be added, it would seem, to show that the power to make such notes a standard of value and a legal tender cannot be derived from the power to borrow money, without so expanding it by implication as to nullify the power to coin money and regulate its value, nor without extending the scope and operation of the power to borrow money to an object never contemplated by the framers of the constitution; and if so, then it only remains to inquire whether it may be implied from the power to declare war, to raise and support armies, or to provide and maintain a navy, or "to enable the government to borrow money to carry on the war," as the phrase is in the dissenting opinion in the former case.

Money is undoubtedly the sinews of war, but the power to raise money to carry on war, under the constitution, is not an implied power, and whoever adopts that theory commits a great constitutional error. Congress may declare war and congress may appropriate all moneys in the treasury to carry on the war, or congress may coin money for that purpose, or borrow money to any amount for the same purpose, or congress may lay and collect taxes, duties, imposts, and excises to replenish the treasury, or may dispose of the public lands or other property belonging to the United States, and may in fact, by the exercise of the express powers of the constitution, command the whole wealth and substance of the people to sustain the public credit and prosecute the war to a successful termination. Two foreign wars were successfully conducted by means derived from those sources, and it is not doubted that those express powers will always enable congress to maintain the national credit and defray the public expenses in every emergency which may arise, even though the national independence should be assailed by the combined forces of all the rest of the civilized world. All remarks, therefore, in the nature of entreaty or appeal, in favor of an implied power to fulfil the great purpose of national defence or to raise money to prosecute a war, are a mere waste of words, as the most powerful and comprehensive means to accomplish the purpose for which the appeal is made are found in the express powers vested in congress to lay and collect taxes, duties, imposts, and excises without limitation as to amount, to borrow money also without limitation, and to coin money, dispose of the public lands, and to appropriate all moneys in the public treasury to that purpose.

Weighed in the light of these suggestions, as the question under discussion should be, it is plain, not only that the exercise of such an implied power is unnecessary to supply the sinews of war, but that the framers of the constitution never intended to trust a matter of such great and vital importance as that of raising means for the national defence or for the prosecution of a war to any implication whatever, as they had learned from bitter experience that the great weakness of the confederation during the war for independence consisted in the want of such express powers. Influenced by those considerations the framers of the constitution not only authorized congress to lay and collect taxes, duties, imposts, and excises to any and every extent, but also to coin money and to borrow money without any limitation as to amount, showing that the argument that to deny the implied power to make paper emissions a legal tender will be to cripple the government, is a mere chimera, without any solid constitutional foundation for its support.

Comprehensive, however, as the power of Federal taxation is, being without limitation as to amount, still there are some restrictions as to the manner of its exercise, and some exceptions as to the objects to which it may be applied. Bills for raising revenue must originate in the house of representatives; duties, imposts, and excises must be uniform throughout the United States; direct taxes must be apportioned according to numbers; regulations of commerce and revenue shall not give any preference to the ports of one state over those of another; nor shall vessels bound to or from one state be obliged to enter, clear, or pay duties in another; nor shall any tax or duty be laid on articles exported from any state.

Preparation for war may be made in peace, but neither the necessity for such preparation nor the actual existence of war can have the effect to abrogate or supersede those restrictions, or to empower congress to tax the articles excepted from taxation by the constitution. Implied exceptions also exist, limiting the power of federal taxation as well as that of the states, and when an exception of that character is ascertained the objects falling within it are as effectually shielded from taxation as those falling within an express exception, for the plain reason that the "government of the United States is acknowledged by all to be one of enumerated powers," from which it necessarily follows that powers not granted cannot be exercised.

Moneys may be raised by taxes, duties, imposts, and excises to carry on war as well as to pay the public debt or to provide for the common defence and general welfare, but no appropriation of money to that use can be made for a period longer than two years, nor can congress, in exercising the power to levy taxes for that purpose, or any other, abrogate or supersede those restrictions, exceptions, and limitations, as they are a part of the constitution, and as such are as obligatory in war as in peace, as any other rule would subvert, in time of war, every restriction, exception, limitation, and prohibition in the constitution, and invest congress with unlimited power, even surpassing that possessed by the British parliament.

Congress may also borrow money to carry on war, without limitation, and in exercising that express power may issue treasury notes as the requisite means for carrying the express power into execution, but congress cannot constitute such notes a standard of value nor make them a legal tender, neither in time of war nor in time of peace, for at least two reasons, either of which is conclusive that the exercise of such a power is not warranted by the constitution: (1.) Because the published proceedings of the convention which adopted the constitution, and of the state conventions which ratified it, show that those who participated in those deliberations never intended to confer any such power. (2.) Because such a power, if admitted to exist, would nullify the effect and operation of the express power to coin money, regulate the value thereof and of foreign coin; as it would substitute a paper medium in the place of gold and silver coin, which in itself, as compared with coin, possesses no value, is not money, either in the constitutional or commercial sense, but only a promise to pay money, is never worth par, and often much less, even as domestic exchange, and is always fluctuating and never acknowledged either as a medium of exchange or a standard of value in any foreign market known to American commerce.

Power to issue such notes, it is conceded, exists without limitation, but the question is whether the framers of the constitution intended that congress, in the exercise of that power or the power to borrow money, whether in peace or war, should be empowered to constitute paper emissions, of any kind, a standard of value, and make the same a legal tender in payment of debts. Mere convenience, or even a financial necessity in a single case, cannot be the test, but the question is, What did the framers of the constitution intend at the time the instrument was adopted and ratified?

Constitutional powers, of the kind last mentioned—that is, the power to ordain a standard of value and to provide a circulating medium for a legal tender—are subject to no mutations of any kind. They are the same in peace and in war. What the grants of power meant when the constitution was adopted and ratified they mean still, and their meaning can never be changed except as described in the fifth article providing for amendments, as the constitution "is a law for rulers and people, equally in war and in peace, and covers with the shield of its protection all classes of men and under all circumstances."
