This is the evil which statesmen should see and provide against. Separation is no remedy; exclusion of Northern vessels from Southern ports is no remedy; but is disunion itself--and upon the very point which caused the Union to be formed. Regulation of commerce between the States, and with foreign nations, was the cause of the formation of the Union. Break that regulation, and the Union is broken; and the broken parts converted into antagonist nations, with causes enough of dissension to engender perpetual wars, and inflame incessant animosities. The remedy lies in the right working of the constitution; in the cessation of unequal legislation in the reduction of the inordinate expenses of the government; in its return to the simple, limited, and economical machine it was intended to be; and in the revival of fraternal feelings, and respect for each other's rights and just complaints; which would return of themselves when the real cause of discontent was removed. The conventions of Augusta and Charleston proposed their remedy for the Southern depression, and the comparative decay of which they complained. It was a fair and patriotic remedy--that of becoming their own exporters, and opening a direct trade in their own staples between Southern and foreign ports. It was recommended--attempted--failed. Superior advantages for navigation in the North--greater aptitude of its people for commerce--established course of business--accumulated capital--continued unequal legislation in Congress; and increasing expenditures of the government, chiefly disbursed in the North, and defect of seamen in the South (for mariners cannot be made of slaves), all combined to retain the foreign trade in the channel which had absorbed it; and to increase it there with the increasing wealth and population of the country, and the still faster increasing extravagance and profusion of the government. And now, at this period (1855), the foreign imports at New York are $195,000,000; at Boston $58,000,000; in Virginia $1,250,000; in South Carolina $1,750,000.
