One result of Southern predominance everybody can appreciate. The national debt is so interwoven with every form of the business and industry of the loyal States that its repudiation would be the most appalling of evils. A tax to pay it at once would not produce half the financial derangement and moral disorder which repudiation would cause; for repudiation, as Mirabeau well observed, is nothing but taxation in its most cruel, unequal, iniquitous, and calamitous form. But what reason have we to think that a reconstructed South, dominant in the Federal government, would regard the debt with feelings similar to ours? The negroes would associate it with their freedom, of which it was the price; their late masters would view it as the symbol of their humiliation, which it was incurred to effect. We must remember that the South loses the whole cost of Rebellion, and is at the same time required to pay its share of the cost of suppressing Rebellion. The cost of Rebellion is, in addition to the devastation of property caused by invasion, the whole Southern debt of some two or three thousand millions of dollars, and the market value of the slaves, which, estimating the slaves at five hundred dollars each, is two thousand millions of dollars more. The portion of the cost of suppressing Rebellion which the South will have to pay can be approximately reached by taking a recent calculation made in the Census Office of the Department of the Interior. Estimating the national debt at twenty-five hundred millions of dollars, and apportioning it according to the number of the white male adults over twenty years of age in the different sections of the country, it has been found that the proportion of the New England States is $308,689,352.07; of the Middle States, $740,195,342.32; of the Western States, $893,288,781.01; of the Southern States, $461,929,846.85; and of the Pacific States, $95,896,677.75. This calculation makes the South responsible for over four hundred and sixty millions of the debt. What amount have the Southerners invested in it? Where both interest and passion furiously impel men to repudiation, can they be trusted with the care of the public credit? "But," the Northern people may exclaim, "in case of such an execrable violation of justice, we would revolt,--we would"----Ah! but in whose hands would then be "the war power"?
