Note 2 — Chapter VII · How the Islanders Determined to be an Honest and Free People.

This labor-saving and danger-avoiding device, moreover, proved so useful, that the idea soon suggested itself that by an extension of the principle involved in the bill of exchange the necessity of carrying gold at all in any quantity might also be avoided. A public office was therefore established, where people might deposit their gold under the guardianship of the state, and receive a ticket or receipt for the amount, payable in coin on demand; which tickets, from the fact that every body knew that they were convertible into gold at will, and that no more tickets were issued than corresponded to gold actually deposited and retained, soon came to be regarded as equally good and valid as gold itself, and vastly more convenient for the purpose of making exchanges. And thus it was that currency (from the Latin curro, to run) originated and came into use on the island as a substitute and representative of money.2 The name originally given to these receipts was first “bank-credits,” and then “bank-notes,” but after a time people acquired a habit of designating them as “paper money.” But this latter term was conceded to be but a mere fiction of speech and a bad use of language; for every intelligent person at once saw that a promise to deliver a commodity, or an acknowledgment of the receipt of, or a title to, a thing, could not possibly be the commodity or the thing itself, any more than a shadow could be the substance, or the picture of a horse a horse, or the smell of a good dinner the same as the dinner itself.
