But turn a moment to the source whence the raw cotton, the basis of these operations, is obtained, and observe the aspect of things in that direction. When the statistics on the subject are examined, it appears that nine-tenths of the cotton consumed in the Christian world is the product of the slave labor of the United States.[14] It is this monopoly that has given to slavery its commercial value; and, while this monopoly is retained, the institution will continue to extend itself wherever it can find room to spread. He who looks for any other result, must expect that nations, which, for centuries, have waged war to extend their commerce, will now abandon that means of aggrandizement, and bankrupt themselves to force the abolition of American slavery! This is not all. The economical value of slavery, as an agency for supplying the means of extending manufactures and commerce, has long been understood by statesmen.[15] The discovery of the power of steam, and the inventions in machinery, for preparing and manufacturing cotton, revealed the important fact, that a single island, having the monopoly secured to itself, could supply the world with clothing. Great Britain attempted to gain this monopoly; and, to prevent other countries from rivaling her, she long prohibited all emigration of skillful mechanics from the kingdom, as well as all exports of machinery. As country after country was opened to her commerce, the markets for her manufactures were extended, and the demand for the raw material increased. The benefits of this enlarged commerce of the world, were not confined to a single nation, but mutually enjoyed by all. As each had products to sell, peculiar to itself, the advantages often gained by one were no detriment to the others. The principal articles demanded by this increasing commerce have been coffee, sugar, and cotton, in the production of which slave labor has greatly predominated. Since the enlargement of manufactures, cotton has entered more extensively into commerce than coffee and sugar, though the demand for all three has advanced with the greatest rapidity. England could only become a great commercial nation, through the agency of her manufactures. She was the best supplied, of all the nations, with the necessary capital, skill, labor, and fuel, to extend her commerce by this means. But, for the raw material, to supply her manufactories, she was dependent upon other countries. The planters of the United States were the most favorably situated for the cultivation of cotton; and while Great Britain was aiming at monopolizing its manufacture, they attempted to monopolize the markets for that staple. This led to a fusion of interests between them and the British manufacturers; and to the adoption of principles in political economy, which, if rendered effective, would promote the interests of this coalition. With the advantages possessed by the English manufacturers, "Free Trade" would render all other nations
