Men are bound by their body, and the body consists of material substances. From this, it is evident that men may not go without a material life. And, on the basis of such material life develop economic phenomena. On the other hand, it is self-evident that material substances are governed by natural laws. The natural laws, in their turn, are endowed with a universal applicability. The economic phenomena, therefore, are invariably universal and general in their nature, having something in common everywhere. This is especially true with the phenomena attendant upon money. As the natural economy advances into classified production, circulation, in whatever form, follows. Circulation, in the first place, presents itself in the form of exchange, which develops at first in the form of barter. It is noted, however, that barter is not without defects, and here comes in money. First, such money takes the form of commodity currency, which, by degrees, evolves itself in metals. The process here begins with the currency by weight and ends with coined money. It is in this stage that money, in its accepted senese, comes in. Further, such coined money urges the appearance of paper money. First, paper money appears in the form of convertible notes, which, subsequently, is followed by incovertible notes, and, further, even by deposit money. It may be said that all these are same everywhere. Seldom does a difference appear according to different countries and different races. True, in China, too, the history of money has followed such a process. Back in the immemorial ancient days, everything was so vague that nothing definite could be stated. However, the following ancient Chinese poem may be taken as an evidence of self-production economy being pursued by people of such remotely ancient times : At sunrise I begin my work, At sunset I take my repose, I dig a well to get my drink, I plow my field to crop my rice ••• why, then, should I e'er care
