because he knew that every other person desirous of exchanging would be willing to do the same. Again: the selection of some commodity or article, and the investing it by common consent with a universal and comparatively unvarying purchasing power, also solved the second perplexity, inasmuch as it provided a measure or standard, for ascertaining the comparative value or purchasing power of every other exchangeable commodity or service; and in precisely the same manner as the length or weight of any thing is ascertained, i.e., by comparing it with some other thing which the community have universally agreed to recognize as a standard of length or weight--as, for example, the rod of wood which we call a yard-stick, or a piece of metal which is termed a pound. "My loaves are each worth ten pieces of the intermediate commodity," said Needum, the baker! "My coat," rejoined Twist, the tailor, "is worth a thousand pieces!" The terms of fair exchange between the baker and the tailor would therefore have been one hundred loaves for one coat. The general name given to the commodities or articles which the people of different countries universally accept in exchange, as the equivalent for all other commodities or services, and as the measure of values, is money. The commodities or articles which have been selected by men at various times and places to serve as this universal equivalent, intermediate agent, or medium for facilitating exchanges, have been exceedingly various. Among the North American Indians, and the early settlers who came among them, wampum and beaver-skins were used as money; among the natives of West Africa, money consists of small shells called "cowries;" in Abyssinia, the common money of to-day is salt; in Chinese Tartary, it is cubes of pressed tea; and within a comparatively recent period small cakes of soap have been used as money on the west coast of Mexico. Among pastoral people of antiquity, cattle and sheep were so extensively used for money that our common English word pecuniary has its derivation from the old word pecus, signifying a flock. And while we read in Homer that the price of the armor of Glaucus was one hundred head of cattle, we also know that the Zulus of South Africa pay their debts to-day in cattle, and reckon their wealth by the same standard. Money, therefore, existed before statutes, and exists and is used to-day among nations who have no written or acknowledged code of laws.
