Under a vigorous national government, the natural strength and resources of the country, directed to a common interest, would baffle all the combinations of European jealousy to restrain our growth. This situation would even take away the motive to such combinations, by inducing an impracticability of success. An active commerce, an extensive navigation, and a flourishing marine would then be the offspring of moral and physical necessity. We might defy the little arts of the little politicians to control or vary the irresistible and unchangeable course of nature. But in a state of disunion, these combinations might exist and might operate with success. It would be in the power of the maritime nations, availing themselves of our universal impotence, to prescribe the conditions of our political existence; and as they have a common interest in being our carriers, and still more in preventing our becoming theirs, they would in all probability combine to embarrass our navigation in such a manner as would in effect destroy it, and confine us to a PASSIVE COMMERCE. We should then be compelled to content ourselves with the first price of our commodities, and to see the profits of our trade snatched from us to enrich our enemies and persecutors. That unequaled spirit of enterprise, which signalizes the genius of the American merchants and navigators, and which is in itself an inexhaustible mine of national wealth, would be stifled and lost, and poverty and disgrace would overspread a country which, with wisdom, might make herself the admiration and envy of the world. There are rights of great moment to the trade of America which are rights of the Union--I allude to the fisheries, to the navigation of the Western lakes, and to that of the Mississippi. The dissolution of the Confederacy would give room for delicate questions concerning the future existence of these rights; which the interest of more powerful partners would hardly fail to solve to our disadvantage. The disposition of Spain with regard to the Mississippi needs no comment. France and Britain are concerned with us in the fisheries, and view them as of the utmost moment to their navigation. They, of course, would hardly remain long indifferent to that decided mastery, of which experience has shown us to be possessed in this valuable branch of traffic, and by which we are able to undersell those nations in their own markets. What more natural than that they should be disposed to exclude from the lists such dangerous competitors?
