One island, which would hardly be missed from the map of the world, so small that its rivers all fall into the sea mere brooks, with not more than one-thirteenth as much coal as we have in the United States, and perhaps not one-hundredth as much iron ore, by the use of steam-driven machinery produces as much iron and perhaps weaves as much cloth yearly as all the rest of the world. If it does not the latter, it would do it, if it could find enough of the raw material and paying customers. But agriculture, which supplies the raw material, though it is the first and most universal form of human labor, lags behind the world's present manufacturing power. One cause of the late, and perhaps of the previous commercial revulsion, was this disproportion. The more rapid enlargement of manufacturing industry, multiplied in power by its machinery, caused the raw material to rise in price and the manufactured article to fall, till the operations could not be supported from the profits at the same time that contracts were fulfilled with capitalists. Manufactures must pause till agriculture overtakes. Steam-machinery applied to agriculture is the only thing that can correct this disproportion, and this is what we are going to make. The world is not to be much longer dependent for its cotton on the compulsory labor of the Dark Ages, nor for its flax and corn on blistered free hands or overworked cattle. The laborer, in either section of our country, will be transformed into an ingenious gentleman or lady, comfortably mounted on a migratory steam-cultivator to direct its gigantic energies,--or, at least, occasionally so occupied. Under this system, it must be plain enough, to all persons prophetically inclined, that the Northern valleys will greatly multiply their products, while the Southern cotton-fields will whiten with heavier crops than human chattelism ever produced, and the mountains of both latitudes, now hardly notched with civilization, will roll down the wool of sheep in clouds.
