inhabitants of each, therefore, will indirectly derive their revenue and maintenance from the other. As the commodities exchanged, too, are supposed to be of equal value, so the two capitals employed in the trade will, upon most occasions, be equal, or very nearly equal; and both being employed in raising the native commodities of the two countries, the revenue and maintenance which their distribution will afford to the inhabitants of each will be equal, or very nearly equal.

This revenue and maintenance, thus mutually afforded, will be greater or smaller in proportion to the extent of their dealings. If these should annually amount to an hundred thousand pounds, for example, or to a million on each side, each of them would afford an annual revenue in the one case of an hundred thousand pounds, in the other of a million, to the inhabitants of the other.
