The kinds of goods chosen for specific claim must, therefore, be capable of test, while, also, that a store may be kept in hand to meet the call of the currency, smallness of bulk, with great relative value, is desirable; and indestructibility, over at least a certain period, essential.
Such indestructibility, and facility of being tested, are united in gold; its intrinsic value is great, and its imaginary value greater; so that, partly through indolence, partly through necessity and want of organization, most nations have agreed to take gold for the only basis of their currencies;—with this grave disadvantage, that its portability enabling the metal to become an active part of the medium of exchange, the stream of the currency itself becomes opaque with gold—half currency and half commodity, in unison of functions which partly neutralize, partly enhance, each other's force.
