How far the other agricultural interests of the United States are promoted, by extending the cultivation of cotton, may be inferred from the Census returns of 1850, and the Congressional Reports on Commerce and Navigation, for 1854.[16] Cotton and tobacco, only, are largely exported. The production of sugar does not yet equal our consumption of the article, and we import, chiefly from slave labor countries, 445,445,680 lbs. to make up the deficiency.[17] But of cotton and tobacco, we export more than _two-thirds_ of the amount produced; while of other products of the agriculturists, less than the _one forty-sixth_ part is exported. Foreign nations, generally, can grow their provisions, but can not grow their tobacco and cotton. Our surplus provisions, not exported, go to the villages, towns, and cities, to feed the mechanics, manufacturers, merchants, professional men, and others; or to the cotton and sugar districts of the South, to feed the planters and their slaves. The increase of mechanics and manufacturers at the North, and the expansion of slavery at the South, therefore, augment the markets for provisions, and promote the prosperity of the farmer. As the mechanical population increases, the implements of industry and articles of furniture are multiplied, so that both farmer and planter can be supplied with them on easier terms. As foreign nations open their markets to cotton fabrics, increased demands for the raw material are made. As new grazing and grain-growing States are developed, and teem with their surplus productions, the mechanic is benefited, and the planter, relieved from food-raising, can employ his slaves more extensively upon cotton. It is thus that our exports are increased; our foreign commerce advanced; the home markets of the mechanic and farmer extended, and the wealth of the nation promoted. It is thus, also, that the free labor of the country finds remunerating markets for its products--though at the expense of serving as an efficient auxiliary in the extension of slavery!
But more: So speedily are new grain-growing States springing up; so vast is the territory owned by the United States, ready for settlement; and so enormous will soon be the amount of products demanding profitable markets, that the national government has been seeking new outlets for them, upon our own continent, to which, alone, they can be advantageously transported. That such outlets, when our vast possessions Westward are brought under cultivation, will be an imperious necessity, is known to every statesman. The farmers of these new States, after the example of those of the older sections of the country, will demand a market for their products. This can be furnished, only, by the extension of slavery; by the acquisition of more tropical territory; by opening the ports of Brazil, and other South American countries, to the admission of our provisions; by their free importation into European countries; or by a vast enlargement of domestic manufactures, to the exclusion of foreign goods from the country. Look at this question as it now stands, and then judge of what it must be twenty years hence. The class of products under consideration, in the whole country, in 1853, were valued at $1,551,176,490; of which there were exported to foreign countries, to the value of only $33,809,126.[18] The planter will not assent to any check upon the foreign imports of the country, for the benefit of the farmer. This demands the adoption of vigorous measures to secure a market for his products by some of the other modes stated. Hence, the orders of our executive, in 1851, for the exploration of the valley of the Amazon; the efforts, in 1854, to obtain a treaty with Brazil, for the free navigation of that immense river; the negotiations for a military foothold in St. Domingo; and the determination to acquire Cuba. But we must not anticipate topics to be considered at a later period in our discussion.
