Note 20 — Chapter VI · ON THE DEFINITION AND APPLICATION OF TERMS BY MR. MILL, IN HIS “ELEMENTS OF POLITICAL ECONOMY.”

Foreign trade is, no doubt, mainly a trade of barter; but the question whether British woollens find an adequate market in the United States, does not depend upon their purchasing the same quantity of tobacco as usual, but upon whether the tobacco, or whatever the returns may be, will purchase the British money or the British labour necessary to enable the woollen manufacturer to carry on his business successfully. If both woollen manufactures and tobacco are below the costs of production in money or labour, both parties may be carrying on a losing trade, at the time when the rate at which the two articles exchange with each other is the same as usual. This is the answer to the pamphlet, which M. Say addressed to me some years ago.
