the first sense, by their falling in value relatively to other things: the same quantity of them exchanging, in the country, for a smaller quantity than before of the other produce of the country. To revert to our original figures; in England, all consumers of linen obtained, after the trade was opened, 17 or some greater number of yards for the same quantity of all other things for which they before obtained only 15. The degree of cheapness, in this sense of the term, depends on the laws of International Demand, so copiously illustrated in the preceding sections. But in the other sense, that of Cost, a country gets a commodity cheaper when it obtains a greater quantity of the commodity with the same expenditure of labour and capital. In this sense of the term, cheapness in a great measure depends upon a cause of a different nature: a country gets its imports cheaper, in proportion to the general productiveness of its domestic industry; to the general efficiency of its labour. The labour of one country may be, as a whole, much more efficient than that of another: all or most of the commodities capable of being produced in both, may be produced in one at less absolute cost than in the other; which, as we have seen, will not necessarily prevent the two countries from exchanging commodities. The things which the more favoured country will import from others, are of course those in which it is least superior; but by importing them it acquires, even in those commodities, the same advantage which it possesses in the articles it gives in exchange for them. Thus the countries which obtain their own productions at least cost, also get their imports at least cost.
This will be made still more obvious if we suppose two competing countries. England sends cloth to Germany, and gives 10 yards of it for 17 yards of linen, or for something else which in Germany is the equivalent of those 17 yards. Another country, as for example France, does the same. The one giving 10 yards of cloth for a certain quantity of German commodities, so must the other: if, therefore, in England,
