The introduction and use of coined money at once gave an impetus to business, and made the people richer, because it saved time and labor in making exchanges, and relieved every man from the trouble and expense of buying and carrying round with him scales and other tests. The only persons dissatisfied were the scale-makers, who found their business almost destroyed, and they petitioned the authorities to have their interests protected by the enactment of a law compelling all persons to weigh their coins with scales before exchanging, as formerly they did their gold. But, as every body at once saw that the effect of such a law would be equivalent to compelling all exchangers to do useless work, the petition amounted to nothing. For convenience in speaking and writing, also, each piece of gold or coin of determinate weight and fineness regularly issued by the mint received a particular name and had a particular device impressed on it. Thus, for example, the piece of lowest denomination, containing 25.8 grains of standard gold, which had on it a likeness of Crusoe's old and faithful servant, was called a "Friday;" a piece of ten times its weight and value, with a small portrait of the founder of the island community, was called a "Crusoe;" and a piece of double the weight of the last, or twenty times the weight of the first, with a large portrait on it, was called a "Robinson Crusoe" or a "double Crusoe." Some time after, when the island became generally known to the rest of the world, it was found that these coins exactly corresponded in weight, fineness, and value with those adopted in that foreign country called the United States, and there known under the names of the gold dollar, eagle, and double-eagle; and after a time, for the purpose of favoring the development of civilization and assimilating nationalities by the adoption of a common monetary standard, it was agreed to discard all local sentiments, and to substitute the latter names for the former. CHAPTER VII. HOW THE ISLANDERS DETERMINED TO BE AN HONEST AND FREE PEOPLE. Next came the consideration of the laws regulating the exchanges and the use of money. Some people wanted laws enacted that every person should be obliged to sell and part with any thing he owned, provided a nominal or real equivalent in what the State should declare money should be offered him; and, also, that when any person had bought commodities and services of another, and had promised to pay for them after a time, he might fully discharge the obligation by tendering that which the State said was money, no matter whether in the mean time the persons in charge of the mint had, for any reasons, taken out one-half the valuable gold in the coins, and substituted in its place comparatively worthless lead.
