bearers, and these in turn are _creditors_, and the legal-tender quality of the greenbacks does not alter their character as a form of pure credit. Both the elements of good faith and future time inhere in the greenbacks, as they do also in the bonds of the United States, while in the certificates neither of these elements appears. However, circumstances easily conceivable and which were actually realized in the case of the famous Bank of Amsterdam, founded in 1609, might make the United States a debtor and the holders of the silver certificates creditors in the commercial sense of those terms. The Directors of the Bank of Amsterdam, towards the close of the second century of its beneficent existence, loaned out to the Dutch East India Company and to the City of Amsterdam large parts of the bullion, on which its certificates ("bank money") were based, unknown to the public, which felt unlimited confidence in the bank, and the result was in 1795, when the French invaded Holland and the facts became known, that bank money which had previously borne a premium of 5% fell at once to a discount of 16%, although the bullion that remained and the debts due the Bank were fully equal to redeem the certificates and were used for that purpose. So, if the United States should use, clandestinely or otherwise, the silver dollars for other purposes than to redeem the certificates on demand, the latter would undoubtedly both in law and fact be transformed from mere token-money (as now) into credit-money valid as against the United States as debtor, like the greenbacks at present. Have we now compassed our first object? Do we fully understand, from the foregoing descriptions and distinctions, the _Nature_ of Credit? If so, we are prepared to look narrowly into its _Forms_. 2. Credit-rights are commonly, but not always, recorded upon paper; but it is important to observe, that the paper-document is the mere evidence of the right, and not the right itself, which lies back of the paper as substance to shadow, and persists intact even were the paper lost or destroyed. These paper instruments of Credit are commonly contemplated as of two kinds, Promises to pay and Orders to pay, but there is not at bottom any radical difference between these, the Right as between two persons is not affected by this superficial difference, as we shall see, and the present enumeration of credit-forms will proceed independently of it.
