Chapter VIII · How the People on the Island Came to Use Currency in the Place of Money.
Reading edition
Nevertheless, as an instrumentality for transferring commodities used for money, and avoiding the loss and waste unavoidable in handling and transporting such commodities, the currency thus devised was a great invention, and being always represented by, or, as we may express it, covered with, the commodity—gold—which, of all things, fluctuates least in value, it perfectly answered the purpose of money, without actually being so. It also furnished another striking illustration of the superiority of the commodity gold to serve either as money or as an object of value for deposit, against which receipts or certificates of deposit might be issued to serve as currency; for if other valuable commodities, like cattle, corn, cloth, or coal, had been selected for a like purpose, the bank would have been obliged to erect large pens, sheds, and warehouses for the storing of the deposits; and, let them be guarded ever so carefully, their value or purchasing power would, after a time, rapidly diminish from natural and unavoidable causes.
