interest in two different ways. First, by raising the price of all foreign goods, and of all sorts of manufactures, it necessarily sinks the real value of the surplus produce of its own land, with which, or, what comes to the same thing, with the price of which, it purchases those foreign goods and manufactures. Secondly, by giving a sort of monopoly of the home market to its own merchants, artificers, and manufacturers, it raises the rate of mercantile and manufacturing profit, in proportion to that of agricultural profit; and, consequently, either draws from agriculture a part of the capital which had before been employed in it, or hinders from going to it a part of what would otherwise have gone to it. This policy, therefore, discourages agriculture in two different ways; first, by sinking the real value of its produce, and thereby lowering the rate of its profits; and, secondly, by raising the rate of profit in all other employments. Agriculture is rendered less advantageous, and trade and manufactures more advantageous, than they otherwise would be; and every man is tempted by his own interest to turn, as much as he can, both his capital and his industry from the former to the latter employments.
Though, by this oppressive policy, a landed nation should be able to raise up artificers, manufacturers, and merchants of its own, somewhat sooner than it could do by the freedom of trade; a matter, however, which is not a little doubtful; yet it would raise them up, if one may say so, prematurely, and before it was perfectly ripe for them. By raising up too hastily one species of industry, it would depress another more valuable species of industry. By raising up too hastily a species of industry which duly replaces the stock which employs it, together with the ordinary profit, it would depress a species of industry which, over and above replacing that stock, with its profit, affords likewise a neat produce, a free rent to the landlord. It would depress productive labour, by encouraging too hastily that labour which is altogether barren and unproductive.
In what manner, according to this system, the sum total of the annual produce of the land is distributed among the three classes above
