The just and candid voice of History has also to thank the Southern statesmen who consented to this arrangement, for having clothed a majority of the two houses of Congress with a full commercial power. They felt, and truly felt, that this was a great concession. But they looked at what they had gained. They had gained the exemption of their staple productions from taxation as objects of foreign commerce; the enumeration of their slaves in the basis of Congressional representation; and the settlement of the slave-trade upon terms not offensive to State pride. They had also gained the Union, with its power to maintain an army and a navy,--with its power and duty to protect them against foreign invasion and domestic insurrection, and to secure their republican constitutions. They looked, therefore, upon the grant of the power to regulate commerce by the ordinary modes of legislation, in its relations to the interests of a great empire, whose foundations ought to be laid broadly and deeply on the national welfare.[229] They saw that the Revolution had cost the Eastern States enormous sacrifices of commercial wealth, and that the weakness of the Confederation had destroyed the little remnant of their trade.[230] They saw and admitted the necessity for an unrestrained control over the foreign commerce of the country, if it was ever to rise from the prostrate condition in which it had been placed by foreign powers. They acted accordingly; and by their action, they enabled the States of North Carolina, South Carolina, and Georgia to enter the new Union without humiliation and without loss.[231]
Thus was accomplished, so far as depended on the action of this Convention, that memorable compromise, which gave to the Union its control over the commercial relations of the States with foreign nations and with each other. An event so fraught with consequences of the utmost importance cannot be dismissed without some of the reflections appropriate to its consideration.
Nature had marked America for a great commercial nation. The sweep of the Atlantic coast, from the Bay of Fundy to the Gulf of Florida, comprehending twenty degrees of latitude, broken into capacious bays and convenient harbors, and receiving the inward flow of the sea into great navigable rivers that stretched far into the interior, presented an access to the ocean not surpassed by that of any large portion of the globe. This long range of sea-coast embraced all the varieties of climate that are found between a hard and sterile region, where summer is but the breath of a few fervid weeks, and the ever blooming tropics, where winter is unknown. The products of the different regions, already entering, or fit to enter, into foreign commerce, attested as great a variety of soils. The proximity of the country to the West Indies, where the Eastern and the Middle States could find the best markets for some of their most important exports, afforded the promise of a highly lucrative trade; while the voyage to the East Indies from any American port could be performed in as short a time as from England or Holland or France. In the South, there were great staples already largely demanded by the consumption of Europe. In the North, there were fisheries of singular importance, capable of furnishing enormous additions to the wealth of the country. Beyond the Alleghanies, the West, with its vast internal waters and its almost unequalled fertility, had been opened to a rapid emigration, which was soon to lay the foundation of new States, destined to be the abodes of millions of men.
