That the new government must have a direct revenue power, was generally conceded, and it was also generally admitted that it must have a power to regulate commerce with foreign countries. But the idea was more or less prevalent among the Southern statesmen, that the interest of their own States, considered as a distinct and separate interest from that of the commercial States, did not require a regulation of commerce by the general government. It is not easy to determine to what extent these views were correct. Taking into consideration nothing more than the fact, that the staple production of Virginia was tobacco, as it was also partly that of North Carolina; that rice and indigo were the great products of South Carolina and Georgia; and that neither of these four States possessed a large amount of shipping;--it might certainly be considered that an unrestricted foreign intercourse was important to them. But, on the other hand, if those States, by clothing the Union with a power to regulate commerce, were likely to subject themselves to a temporary rise of freights, the measures which might have that effect would also tend directly to increase Southern as well as Northern shipping, to augment the commercial marine of the whole country, and thus to increase its general maritime strength. The general security thus promoted was as important to one class of States as to another. The increase of the coasting trade would also increase the consumption of the produce of all the States. The great benefit, however, to be derived from a national regulation of commerce,--a benefit in which all the States would equally share, whatever might be their productions,--was undoubtedly the removal of the existing and injurious retaliations which the States had hitherto practised against each other.[216] Still, these advantages were indirect or incidental. The immediate and palpable commercial interests of different portions of the Union, regarded in the mass, were not identical; and it was in one sense true, that the power of regulating commerce was a concession on the part of the Southern States to the Northern, for which they might reasonably expect equivalent advantages, or which they might reasonably desire to qualify by some restriction.
