The interpretation given by Mr. Hamilton was substantially followed by Chief Justice Marshall, in McCulloch v. the State of Maryland, when, speaking for the court, he said that if the end to be accomplished by the legislation of congress be legitimate, and within the scope of the constitution, "all the means which are appropriate, which are plainly adapted to that end, and which are not prohibited, but are consistent with the letter and spirit of the constitution, are constitutional." The chief justice did not, it is true, in terms declare that legislation which is not thus appropriate, and plainly adapted to a lawful end, is unconstitutional, but such is the plain import of the argument advanced by him; and that conclusion must also follow from the principle that, when legislation of a particular character is specially authorized, the opposite of such legislation is inhibited.

Tested by the rule given by Mr. Hamilton, or by the rule thus laid down by this court through Mr. Chief Justice Marshall, the annexing of a quality to the promises of the government for money borrowed, which will enable the holder to use them as a means of satisfying the demands of third parties, cannot be sustained as the exercise of an appropriate means of borrowing. That is only appropriate which has some relation of fitness to an end. Borrowing, as already stated, is a transaction by which, on one side, the lender parts with his money, and on the other the borrower agrees to repay it in such form and at such time as may be stipulated. Though not a necessary part of the contract of borrowing, it is usual for the borrower to offer securities for the repayment of the loan. The fitness which would render a means appropriate to this transaction thus considered must have respect to the terms which are essential to the contract, or to the securities which the borrower may furnish as an inducement to the loan. The quality of legal tender does not touch the terms of the contract of borrowing, nor does it stand as a security for the loan. A security supposes some right or interest in the thing pledged, which is subject to the disposition of the borrower.

There has been much confusion on this subject from a failure to distinguish between the adaptation of particular means to an end and the effect, or supposed effect, of those means in producing results desired by the government. The argument is stated thus: the object of borrowing is to raise funds; the annexing of the quality of legal tender to the notes of the government induces parties the more readily to loan upon them; the result desired by the government—the acquisition of funds—is thus accomplished; therefore, the annexing of the quality of legal tender is an appropriate means to the execution of the power to borrow. But it is evident that the same reasoning would justify, as appropriate means to the execution of this power, any measures which would result in obtaining the required funds. The annexing of a provision by which the notes of the government should serve as a free ticket in the public conveyances of the country, or for ingress into places of public amusement, or which would entitle the holder to a percentage out of the revenues of private corporations, or exempt his entire property, as well as the notes themselves, from state and municipal taxation, would produce a ready acceptance of the notes. But the advocate of the most liberal construction would hardly pretend that these measures, or similar measures touching the property of third parties, would be appropriate as a means to the execution of the power to borrow. Indeed, there is no invasion by government of the rights of third parties which might not thus be sanctioned upon the pretence that its allowance to the holder of the notes would lead to their ready acceptance and produce the desired loan.

The actual effect of the quality of legal tender in inducing parties to receive them was necessarily limited to the amount required by existing debtors, who did not scruple to discharge with them their pre-existing liabilities. For moneys desired from other parties, or supplies required for the use of the army or navy, the provision added nothing to the value of the notes. Their borrowing power or purchasing power depended, by a general and a universal law of currency, not upon the legal tender clause, but upon the confidence which the parties receiving the notes had in their ultimate payment. Their exchangeable value was determined by this confidence, and every person dealing in them advanced his money and regulated his charges accordingly.

The inability of mere legislation to control this universal law of currency is strikingly illustrated by the history of the bills of credit issued by the Continental congress during our Revolutionary war. From June, 1775, to March, 1780, these bills amounted to over $300,000,000. Depreciation followed as a natural consequence, commencing in 1777, when the issues only equalled $14,000,000. Previous to this time, in January, 1776, when the issues were only $5,000,000, congress had, by resolution, declared that if any person should be "so lost to all virtue and regard to his country" as to refuse to receive the bills in payment, he should, on conviction thereof by the committee of the city, county, or district, or, in case of appeal from their decision, by the assembly, convention, council, or committee of safety of the colony where he resided, be "deemed, published, and treated as an enemy of his country, and precluded from all trade or intercourse with the inhabitants" of the colonies.

And in January, 1777, when as yet the issues were only $14,000,000, congress passed this remarkable resolution:

"Resolved, That all bills of credit emitted by authority of congress ought to pass current in all payments, trade, and dealings in these states, and be deemed in value equal to the same nominal sums in Spanish milled dollars, and that whosoever shall offer, ask, or receive more in the said bills for any gold or silver coins, bullion, or any other species of money whatsoever, than the nominal sum or amount thereof in Spanish milled dollars, or more in the said bills for any lands, houses, goods, or commodities whatsoever than the same could be purchased at of the same person or persons in gold, silver, or any other species of money whatsoever, or shall offer to sell any goods or commodities for gold or silver coins or any other species of money whatsoever and refuse to sell the same for the said continental bills, every such person ought to be deemed an enemy to the liberty of these United States and to forfeit the value of the money so exchanged, or house, land, or commodity so sold or offered for sale. And it is recommended to the legislatures of the respective states to enact laws inflicting such forfeitures and other penalties on offenders as aforesaid as will prevent such pernicious practices. That it be recommended to the legislatures of the United States to pass laws to make the bills of credit issued by the congress a lawful tender in payments of public and private debts, and a refusal thereof an extinguishment of such debts; that debts payable in sterling money be discharged with continental dollars at the rate of 4s. 6d. sterling per dollar, and that in discharge of all other debts and contracts continental dollars pass at the rate fixed by the respective states for the value of Spanish milled dollars."

The several states promptly responded to the recommendations of congress and made the bills a legal tender for debts and the refusal to receive them an extinguishment of the debt.

Congress also issued, in September, 1779, a circular addressed to the people on the subject, in which they showed that the United States would be able to redeem the bills, and they repelled with indignation the suggestion that there could be any violation of the public faith. "The pride of America," said the address, "revolts from the idea; her citizens know for what purposes these emissions were made, and have repeatedly plighted their faith for the redemption of them; they are to be found in every man's possession, and every man is interested in their being redeemed; they must, therefore, entertain a high opinion of American credulity who suppose the people capable of believing, on due reflection, that all America will, against the faith, the honor, and the interest of all America, be ever prevailed upon to countenance, support, or permit so ruinous, so disgraceful a measure. We are convinced that the efforts and arts of our enemies will not be wanting to draw us into this humiliating and contemptible situation. Impelled by malice and the suggestions of chagrin and disappointment at not being able to bend our necks to the yoke, they will endeavor to force or seduce us to commit this unpardonable sin in order to subject us to the punishment due to it, and that we may thenceforth be a reproach and a by-word among the nations. Apprised of these consequences, knowing the value of national character, and impressed with a due sense of the immutable laws of justice and honor, it is impossible that America should think without horror of such an execrable deed."

Yet in spite of the noble sentiments contained in this address, which bears the honored name of John Jay, then president of congress and afterwards the first chief justice of this court, and in spite of legal tender provisions and harsh penal statutes, the universal law of currency prevailed. Depreciation followed until it became so great that the very idea of redemption at par was abandoned.
