Promissory notes, interchanged between scheming individuals, are liberally discounted at the banks, which become so many mints to coin words into cash; and as the supply of words is inexhaustible, it may readily be supposed what a vast amount of promissory capital is soon in circulation. Every one now talks in thousands; nothing is heard but gigantic operations in trade; great purchases and sales of real property, and immense sums made at every transfer. All, to be sure, as yet exists in promise; but the believer in promises calculates the aggregate as solid capital, and falls back in amazement at the amount of public wealth, the "unexampled state of public prosperity." Now is the time for speculative and dreaming or designing men. They relate their dreams and projects to the ignorant and credulous, dazzle them with golden visions, and set them madding after shadows. The example of one stimulates another; speculation rises on speculation; bubble rises on bubble; every one helps with his breath to swell the windy superstructure, and admires and wonders at the magnitude of the inflation he has contributed to produce. Speculation is the romance of trade, and casts contempt upon all its sober realities. It renders the stock-jobber a magician, and the exchange a region of enchantment. It elevates the merchant into a kind of knight-errant, or rather a commercial Quixote. The slow but sure gains of snug percentage become despicable in his eyes; no "operation" is thought worthy of attention that does not double or treble the investment. No business is worth following that does not promise an immediate fortune. As he sits musing over his ledger, with pen behind his ear, he is like La Mancha's hero in his study, dreaming over his books of chivalry. His dusty counting-house fades before his eyes, or changes into a Spanish mine; he gropes after diamonds, or dives after pearls. The subterranean garden of Aladdin is nothing to the realms of wealth that break upon his imagination. Could this delusion always last, the life of a merchant would indeed be a golden dream; but it is as short as it is brilliant. Let but a doubt enter, and the "season of unexampled prosperity" is at end. The coinage of words is suddenly curtailed; the promissory capital begins to vanish into smoke; a panic succeeds, and the whole superstructure, built upon credit and reared by speculation, crumbles to the ground, leaving scarce a wreck behind: "It is such stuff as dreams are made of."
