anticipated a vast market for our manufacturing industry, and an ample compensation for the diminution of our shipping interest. Nature has established this great and all-important distinction between the effects of wealth and national age on the productions of agriculture and of manufactures. The reason is this:--If capital, machinery, and knowledge, conferred the same immediate and decisive advantage on agricultural that they do on manufacturing industry, old and densely-peopled states would possess an undue superiority over the ruder and more thinly-inhabited ones; the multiplication of the human race would become excessive in the seats in which it had first taken root, and the desert parts of the world would never, but under the pressure of absolute necessity, be explored. The first command of God to man, "Be fruitful, and multiply, and replenish the earth, and subdue it," would be frustrated. The apprehensions of the Malthusians as to an excessive increase of mankind, with its attendant dangers, would be realized in particular places, while nineteen-twentieths of the earth lay neglected in a state of nature. The desert would be left alone in its glory. The world would be covered with huge and densely-peopled excrescences--with Babylons, Romes, and Londons--in which wealth, power, and corruption were securely and permanently intrenched, and from which the human race would ne'er diverge but under the pressure of absolute impossibility to wrench a subsistence from their over-peopled vicinities.
