After this, every thing for a time pertaining to trade and commerce went on very smoothly on the island. It is true there were bad persons who obtained commodities and services on credit for which they never intended to pay; careless and extravagant persons who bought more than they were able to pay for; and foolish and oversanguine people who, after having by labor and economy accumulated a good store of commodities, exchanged them for shares in enterprises which never could pay. And when people by one or more of such methods lost the results of their hard labor and toil, they naturally felt depressed, lost confidence in their fellow-men, and thought times and things might be improved by turning all those in office out, and putting new men in. But no one on the island ever for a moment imagined that there was any way to honestly replace the money they had lost, except by acquiring through industry and economy a new store of useful commodities with which to buy money; and no one who ever had any thing to sell which others in the community wanted, and were able to give in return a fair equivalent, ever found himself in want of money or a market; while, on the other hand, no one who had nothing to sell which the community wanted or were able to pay for ever succeeded in obtaining either money or a market. CHAPTER VIII. HOW THE PEOPLE ON THE ISLAND CAME TO USE CURRENCY IN THE PLACE OF MONEY. As time went on, changes in the method of doing business gradually occurred on the island. Instead of being an isolated and unknown community, their existence as an organized, civilized state became generally known to the rest of the world, and a brisk trade and commerce resulted from the exchange of the products of the island for the products of other countries. An excellent harbor existed at each end of the island, and about these points the population naturally aggregated, and built up two very considerable towns. The middle of the island, on the other hand, was elevated into high mountain ranges, covered with dense forests, in crossing which travelers journeying between the two cities were often robbed of all the gold they carried about them. To obviate this danger, and avoid the necessity of carrying gold, persons living at opposite ends of the island, therefore, adopted a system of giving written orders for money on each other, which each reciprocally agreed to pay to the person whose name was written in the order or draft, and then periodically settled or balanced their accounts by offsetting one order or payment against another. In this way value or purchasing power was transmitted long distances much more cheaply and conveniently than could be effected by the transmission of gold itself; and also much more safely, inasmuch as the thieves could make no use of the orders, even if they obtained them. And thus it was that the people on the island became acquainted with and first used what were afterward known as "bills of exchange." [14]
