The peculiar properties of the precious metals described above (§ 120), explains satisfactorily enough, why, at the same time, but in different countries, they have more nearly the same value in exchange than any other commodity whatever. Like a fluid in tubes which communicate with one another, the precious metals seek the one same level of value the whole world over.(762) Only, it must not be supposed that every absolute or relative increase of the amount of money in a country must produce immediately a corresponding diminution of the value of money; and in addition to this cause an exportation of money.(763) If the number of trade-transactions increases in the same proportion as the amount of money, the value of money remains entirely unaffected.(764) The same thing occurs when the increased influx of money, instead of overflowing the channels of circulation, only swells the volume in the ready-money reservoirs. By means of these stores of ready money, very large payments may be made by one nation to another, without changing the circulation, or, therefore, the value of money, in the slightest degree, on either side.(765) If, indeed, such payments should continue for a long time to flow in the same direction, they would certainly influence the circulation, and then produce a current in the opposite direction. However, it may happen, that the value of money in different countries may be permanently different, when there are lasting difficulties in the way of the leveling influence of the incoming or outgoing current of money. Thus, the precious metals maintain a high value in those countries especially which can obtain them only by giving commodities difficult of transportation for them. If, for instance, an Englishman, anxious to take advantage of the high value of money in Poland, should cause Polish articles, such as wheat, wood, wool etc., to be imported into England, they would reach their destination very much increased in price, because of the great cost of transportation. Whether Poland or England would have to bear this cost depends on the relations of supply and demand. Certain it is, however, that the migration of money is hereby rendered exceedingly difficult, forbidden even within the limits of certain value-differences, especially where the means of communication are universally bad. And so, the smaller the number of countries which minister to the want of commodities of precious-metal districts, the more must other nations obtain the money they need only at second and third hand; by means of which, naturally, money itself is made dearer each time. Now, it is, as a rule, nations in a low stage of civilization, that engage in the exportation of raw material, and they are the worst adapted to engaging directly in the carrying on of trade. When, therefore, they do not possess gold or silver mines themselves, money-value is, as a rule, highest with them; especially as the absence of legal security and protection, which
