Nor is the difference less important and conspicuous in the _price_ at which manufacturing and agricultural produce can be raised in the old and the young state. This is the decisive circumstance which renders reciprocity between them impossible. The rich old state is as superior to the young one in the production of manufactures, as the poor young state is to the rich old one in that of subsistence. The steam-engine, capital, and machinery, have so enormously increased the power of manufacturing production, that they have rendered the old commercial state omnipotent in the foreign market in the supply of its articles. Nothing but fiscal regulations and heavy duties can protect the young state from ruin in those branches of industry. Heavy taxes, high wages, costly rents, dear rude produce, all are at once compensated, and more than compensated, by the gigantic powers of the steam-engine. Cotton goods are raised now in Great Britain at a fifth of the price which they were during the war. A gown, which formerly was cheap at £2, 10s., is now sold for ten shillings. Silks, muslins, and all other articles of female apparel, have been reduced in price in the same proportion. Colossal fortunes have been made by the master manufacturers, unbounded wealth diffused through the operative workmen in Lancashire and Lanarkshire, even at these extremely reduced prices. This is the real reason of the universal effort made by all nations which have the least pretensions to commercial industry, of late years to exclude, by fixed duties, our staple manufactures; of which the President of the Board of Trade so feelingly complains, and which the advocates of free trade consider as so inexplicable. A very clear principle has led to it, and will lead to it. It is the instinct of SELF-PRESERVATION.
