The Wealth of Nations_ Books 4-5 - Adam Smith [37]
The enormous expense of the late war, therefore, must have been chiefly defrayed, not by the exportation of gold and silver, but by that of British commodities of some kind or other. When the government, or those who acted under them, contracted with a merchant for a remittance to some foreign country, he would naturally endeavour to pay his foreign correspondent, upon whom he had granted a bill, by sending abroad rather commodities than gold and silver.

Both are employed in facilitating exchanges, the one between different individuals of the same, the other between those of different nations. Part of this money of the great mercantile republic may have been, and
