9. For this you have every inducement of sympathy and interest. Citizens, by birth or choice, of a common country, that country has a right to concentrate your affections. The name of America, which belongs to you in your national capacity, must always exalt the just pride of patriotism, more than any appellation derived from local discriminations. With slight shades of difference, you have the same religion, manners, habits, and political principles. You have in a common cause fought and triumphed together; the independence and liberty you possess are the work of joint councils and joint efforts, of common dangers, sufferings, and successes. But these considerations, however powerfully they address themselves to your sensibility, are greatly outweighed by those which apply more immediately to your interest; here every portion of our country finds the most commanding motives for carefully guarding and preserving the union of the whole. 10. The North, in an unrestrained intercourse with the South, protected by the equal laws of a common government, finds in the productions of the latter great additional resources of maritime and commercial enterprise, and precious materials of manufacturing industry. The South, in the same intercourse, benefiting by the agency of the North, sees its agriculture grow and its commerce expand. Turning partly into its own channels the seamen of the North, it finds its particular navigation invigorated; and while it contributes, in different ways, to nourish and increase the general mass of the national navigation, it looks forward to the protection of a maritime strength, to which itself is unequally adapted. The East, in a like intercourse with the West, already finds, and in the progressive improvement of interior communications by land and water will more and more find, a valuable vent for the commodities which it brings from abroad, or manufactures at home. The West derives from the East supplies requisite to its growth and comfort; and what is perhaps of still greater consequence, it must of necessity owe the secure enjoyment of indispensable outlets for its own productions to the weight, influence, and the future maritime strength of the Atlantic side of the Union, directed by an indissoluble community of interest as _one nation_. Any other tenure by which the West can hold this essential advantage, whether derived from its own separate strength, or from an apostate and unnatural connection with any foreign power, must be intrinsically precarious.
