cure the remaining 200, which she would have no means of doing but by bidding higher for them, she would offer more than 17 yards of linen in exchange for 10 yards of cloth; let us suppose her to offer 18. At that price, perhaps, England would be inclined to purchase a greater quantity of linen. She would consume, possibly, at that price, 900 times 18 yards. On the other hand, cloth having risen in price, the demand of Germany for it would probably have diminished. If, instead of 1000 times 10 yards, she is now contented with 900 times 10 yards, these will exactly pay for the 900 times 18 yards of linen which England is willing to take at the altered price; the demand on each side will again exactly suffice to take off the corresponding supply; and 10 yards for 18 will be the rate at which, in both countries, cloth will exchange for linen.

"The converse of all this would have happened, if instead of 800 times 17 yards, we had supposed that England, at the rate of 10 for 17, would have taken 1200 times 17 yards of linen. In this case, it is England whose demand is not fully supplied; it is England who, by bidding for more linen, will alter the rate of interchange to her own disadvantage; and 10 yards of cloth will fall, in both countries, below the value of 17 yards of linen. By this fall of cloth, or what is the same thing, this rise of linen, the demand of Germany for cloth will increase, and the demand of England for linen will diminish, till the rate of interchange has so adjusted itself that the cloth and the linen will exactly pay for one another; and when once this point is attained, values will remain without further alteration.

"It may be considered, therefore, as established, that when two countries trade together in two commodities, the exchange value of these commodities relatively to each other will adjust itself to the inclinations and circumstances of the consumers on both sides, in such manner that the quantities required by each country, of the articles which

it imports from its neighbor, shall be exactly sufficient to pay for one another. As the inclinations and circumstances of consumers cannot be reduced to any rule, so neither can the proportions in which the two commodities will be interchanged. We know that the limits within which the variation is confined, are the ratio between their costs of production in the one country, and the ratio between their costs of production in the other. Ten yards of cloth cannot exchange for more than 20 yards of linen, nor for less than 15. But they may exchange for any intermediate number. The ratios, therefore, in which the advantage of the trade may be divided between the two nations, are various. The circumstances on which the proportionate share of each country more remotely depends, admit only of a very general indication.

"It is even possible to conceive an extreme case, in which the whole of the advantage resulting from the interchange would be reaped by one party, the other country gaining nothing at all. There is no absurdity in the hypothesis that, of some given commodity, a certain quantity is all that is wanted at any price; and that, when that quantity is obtained, no fall in the exchange value would induce other consumers to come forward, or those who are already supplied, to take more. Let us suppose that this is the case in Germany with cloth. Before her trade with England commenced, when 10 yards of cloth cost her as much labor as 20 yards of linen, she nevertheless consumed as much cloth as she wanted under any circumstances, and, if she could obtain it at the rate of 10 yards of cloth for 15 of linen, she would not consume more. Let this fixed quantity be 1000 times 10 yards. At the rate, however, of 10 for 20, England would want more linen than would be equivalent to this quantity of cloth. She would consequently, offer a higher value for linen; or, what is the same thing, she would offer her cloth at a cheaper rate.

But, as by no lowering of the value could she prevail on Germany to take a greater quantity of cloth, there would be no limit to the rise of linen or fall of cloth, until the demand of England for linen was reduced by the rise of its value, to the quantity which 1000 times 10 yards of cloth would purchase. It might be, that to produce this diminution of the demand, a less fall would not suffice than that which would make 10 yards of cloth exchange for 15 of linen. Germany would then gain the whole of the advantage, and England would be exactly as she was before the trade commenced. It would be for the interest, however, of Germany herself to keep her linen a little below the value at which it could be produced in England, in order to keep herself from being supplanted by the home producer. England, therefore, would always benefit in some degree by the existence of the trade, though it might be in a very trifling one."

In this statement, I conceive, is contained the principle of International Values; which it only remains to follow into its applications. I have, as is indispensable in such abstract and hypothetical cases, supposed the circumstances to be much less complex than they really are in the first place, by suppressing the cost of carriage; next, by supposing that there are only two countries trading together; and lastly, that they trade only in two commodities. To complete the exposition, it is necessary to restore the various circumstances thus temporarily left out to simplify the argument. Those who are accustomed to any kind of scientific investigation will probably see, without formal proof, that the introduction of these circumstances cannot alter the theory of the subject. Trade among any number of countries, and in any number of commodities, must take place on the same essential principles as trade between two countries and in two commodities. Introducing a greater number of agents precisely similar, cannot

change the law of their action, no more than putting additional weights into the two scales of a balance alters the law of gravitation. It alters nothing but the numerical results. For more complete satisfaction, however, we will enter into the complex cases with the same particularity with which we have stated the simpler one.

3. First, let us introduce the element of cost of carriage. The chief difference will then be, that the cloth and the linen will no longer exchange for each other at precisely the same rate in both countries. Linen, having to be carried to England, will be dearer there by its cost of carriage; and cloth will be dearer in Germany by the cost of carrying it from England. Linen, estimated in cloth, will be dearer in England than in Germany, by the cost of carriage of both articles; and so will cloth in Germany, estimated in linen. Suppose that the cost of carriage of each is equivalent to one yard of linen; and suppose that, if they could have been carried without cost, the terms of interchange would have been 10 yards of cloth for 17 of linen. It seems at first that each country will pay its own cost of carriage; that is, the carriage of the article it imports; that in Germany 10 yards of cloth will exchange for 18 of linen, namely the original 17, and 1 to cover the cost of carriage of the cloth; while in England, 10 yards of cloth will only purchase 16 of linen, 1 yard being deducted for the cost of carriage of the linen. This, however, cannot be affirmed with certainty; it will only be true, if the linen which the English consumers would take at the price of 10 for 16, exactly pays for the cloth which the German consumers would take at 10 for 18. The values must be those, whatever they are, which will establish this equilibrium. No absolute rule, therefore, can be laid down for the division of the cost, no more than for the division of the advantage; and it does not follow that in

whatever ratio the one is divided, the other will be divided in the same. It is impossible to say, if the cost of carriage could be annihilated, whether the producing or the importing country would be most benefited. All would depend on the play of international demand.

But for it, every

Cost of carriage has one effect more. commodity would be either regularly imported or regularly exported. A country would make nothing for itself which it did not also make for other countries. But in consequence of cost of carriage, there are many things, especially bulky articles, which every or almost every country produces within itself. After exporting the things in which it can employ itself most advantageously, and importing those in which it is under the greatest disadvantage, there are many lying between, of which the relative cost of production in that and in other countries differs so little, that the cost of carriage would absorb more than the whole saving in cost of production which would be obtained by importing one and exporting another. This is the case with numerous commodities of common consumption; including the coarser qualities of many articles of food and manufacture, of which the finer kinds are the subject of extensive international traffic.

§ 4. Let us now introduce a greater number of commodities than the two we have hitherto supposed. Let cloth and linen, however, be still the articles of which the comparative cost of production in England and in Germany differs the most; so that if they were confined to two commodities, these would be the two which it would be most their interest to exchange. We will now again omit cost of carriage, which, having been shown not to affect the essentials of the question, does but embarrass unnecessarily the statement of it. Let us suppose, then, that the demand of England for linen is either so much greater than that of
