out, they will sell for less or more of it, exactly according as less or more is brought.

3. From what precedes, it might for a moment be supposed, that all the goods on sale in a country at any one time, are exchanged for all the money existing and in circulation at that same time: or, in other words, that there is always in circulation in a country, a quantity of money equal in value to the whole of the goods then and there on sale. But this would be a complete misapprehension. The money laid out is equal in value to the goods it purchases; but the quantity of money laid out is not the same thing with the quantity in circulation. As the money passes from hand to hand, the same piece of money is laid out many times, before all the things on sale at one time are purchased and finally removed from the market: and each pound or dollar must be counted for as many pounds or dollars, as the number of times it changes hands in order to effect this object. The greater part of the goods must also be counted inore than once, not only because most things pass through the hands of several sets of manufacturers and dealers before they assume the form in which they are finally consumed, but because in times of speculation (and all times are so, more or less) the same goods are often bought repeatedly, to be resold for a profit, before they are bought for the purpose of consumption at all.

If we assume the quantity of goods on sale, and the number of times those goods are resold, to be fixed quantities, the value of money will depend upon its quantity, together with the average number of times that each piece changes hands in the process. The whole of the goods sold (counting each resale of the same goods as so much added to the goods) have been exchanged for the whole of the money, multiplied by the number of purchases made on the average by each piece. Consequently, the amount of goods and of transactions being the same, the value of money is inversely as its quantity multiplied by what is called the

rapidity of circulation. And the quantity of money in cir culation, is equal to the money value of all the goods sold, divided by the number which expresses the rapidity of cir culation.

The phrase, rapidity of circulation, requires some comment. It must not be understood to mean, the number of purchases made by each piece of money in a given time. Time is not the thing to be considered. The state of society may be such, that each piece of money hardly performs more than one purchase in a year; but if this arises from the small number of transactions-from the small amount of business done, the want of activity in traffic, or because what traffic there is, mostly takes place by barter—it constitutes no reason why prices should be lower, or the value of money higher. The essential point is, not how often the same money changes hands in a given time, but how often it changes hands in order to perform a given amount of traffic. We must compare the number of purchases made by the money in a given time, not with the time itself, but with the goods sold in that same time. If each piece of money changes hands on an average ten times while goods are sold to the value of a million sterling, it is evident that the money required to circulate those goods is 100,0007. And conversely, if the money in circulation is 100,000l., and each piece changes hands by the purchase of goods ten times in a month, the sales of goods for money which take place every month must amount on the average to 1,000,0007.

Rapidity of circulation being a phrase so ill adapted to express the only thing which it is of any importance to express by it, and having a tendency to confuse the subject by suggesting a meaning extremely different from the one intended, it would be a good thing if the phrase could be got rid of, and another substituted, more directly significant of the idea meant to be conveyed. Some such expression as "the efficiency of money," though not unexceptionable, would do better; as it would point attention to the quantity of work done, without suggesting the idea of estimating

it by time. Until an appropriate term can be devised, we must be content when ambiguity is to be apprehended, to express the idea by the circumlocution which alone conveys it adequately, namely, the average number of purchases made by each piece in order to affect a given pecuniary

amount of transactions.

§ 4. The proposition which we have laid down respecting the dependence of general prices upon the quantity of money in circulation, must be understood as applying only to a state of things in which money, that is, gold or silver, is the exclusive instrument of exchange, and actually passes from hand to hand at every purchase, credit in any of its shapes being unknown. When credit comes into play as a means of purchasing, distinct from money in hand, we shall hereafter find that the connexion between prices and the amount of the circulating medium is much less direct and intimate, and that such connexion as does exist, no longer admits of so simple a mode of expression. But on a subject so full of complexity as that of currency and prices, it is necessary to lay the foundation of our theory in a thorough understanding of the most simple cases, which we shall always find lying as a groundwork or substratum under those which arise in practice. That an increase of the quantity of money raises prices, and a diminution lowers them, is the most elementary proposition in the theory of currency, and without it we should have no key to any of the others. In In any state of things, however, except the simple and primitive one. which we have supposed, the proposition is only true other things being the same: and what those other things are, which must be the same, we are not yet ready to pronounce. We can, however, point out, even now, one or two of the cautions with which the principle must be guarded in attempting to make use of it for the practical explanation of phenomena; cautions the more indispensable, as the doctrine, though a scientific truth, has of late years been the foundation of a greater mass of false theory, and erroneous

interpretation of facts, than any other proposition relating to interchange. From the time of the resumption of cash payments by the Act of 1819, and especially since the commercial crisis of 1825, the favourite explanation of every rise or fall of prices has been "the currency;" and like most popular theories, the doctrine has been applied with little regard to the conditions necessary for making it correct.

For example, it is habitually assumed that whenever there is a greater amount of money in the country, or in existence, a rise of prices must necessarily follow. But this is by no means an inevitable consequence. In no commodity is it the quantity in existence, but the quantity offered for sale, that determines the value. Whatever may be the quantity of money in the country, only that part of it will affect prices, which goes into the market of commodities, and is there actually exchanged against goods. Whatever increases the amount of this portion of the money in the country, tends to raise prices. But money hoarded does not act on prices. Money kept in reserve by individuals to meet contingencies which do not occur, does not act on prices. The money in the coffers of the Bank, or retained as a reserve by private bankers, does not act on prices until drawn out, nor even then unless drawn out to be expended in commodities.

It frequently happens that money, to a considerable amount, is brought into the country, is there actually invested as capital, and again flows out, without having ever once acted upon the markets of commodities, but only upon the market of securities, or, as it is commonly though improperly called, the money market. Let us return to the case already put for illustration, that of a foreigner landing in the country with a treasure. We supposed him to employ his treasure in the purchase of goods for his own use, or in setting up a manufactory and employing labourers; and in either case he would, cateris paribus, raise prices. But instead of doing either of these things, he might very probably prefer to invest his fortune at interest; which we

shall suppose him to do in the most obvious way, by becom ing a competitor for a portion of the stock, exchequer bills, railway debentures, mercantile bills, mortgages, &c., which are at all times in the hands of the public. By doing this he would raise the prices of those different securities, or in other words would lower the rate of interest; and since this would disturb the relation previously existing between the rate of interest on capital in the country itself, and that in foreign countries, it would probably induce some of those who had floating capital seeking employment, to send it abroad for foreign investment, rather than buy securities at home at the advanced price. As much money might thus go out as had previously come in, while the prices of commodities would have shown no trace of its temporary presence. This is a case highly deserving of attention and it is a fact now beginning to be recognised, that the passage of the precious metals from country to country is determined much more than was formerly supposed, by the state of the loan market in different countries, and much less by the state of prices.

Another point must be adverted to, in order to avoid serious error in the interpretation of mercantile phenomena. If there be, at any time, an increase in the number of money transactions, a thing continually liable to happen from differences in the activity of speculation, and even in the time of year (since certain kinds of business are transacted only at particular seasons); an increase of the currency which is only proportional to this increase of transactions, and is of no longer duration, has no tendency to raise prices. At the quarterly periods when the public dividends are paid at the Bank, a sudden increase takes place of the money in the hands of the public; an increase estimated at from a fifth to two-fifths of the whole issues of the Bank of England. Yet this never has any effect on prices; and in a very few weeks, the currency has again shrunk into its usual dimensions, by a mere reduction in the demands of the public (after so copious a supply of ready money) for accom
