It will be observed that we have omitted the Territories and the District of Columbia in all the preceding tables. We did this purposely. Our object was to draw an equitable comparison between the value of free and slave labor in the thirty-one sovereign States, where the two systems, comparatively unaffected by the wrangling of politicians, and, as a matter of course, free from the interference of the general government, have had the fullest opportunities to exert their influence, to exhibit their virtues, and to commend themselves to the sober judgments of enlightened and discriminating minds. Had we counted the Territories on the side of the North, and the District of Columbia on the side of the South, the result would have been still greater in behalf of free labor. Though "the sum of all villanies" has but a mere nominal existence in Delaware and Maryland, we have invariably counted those States on the side of the South; and the consequence is, that, in many particulars, the hopeless fortunes of slavery have been propped up and sustained by an imposing array of figures which of right ought to be regarded as the property of freedom. But we like to be generous to an unfortunate foe, and would utterly disdain the use of any unfair means of attack or defence. We shall take no undue advantage of slavery. It shall have a fair trial, and be judged according to its deserts. Already has it been weighed in the balance, and found wanting; it has been measured in the half-bushel, and found wanting; it has been apprized in the field, and found wanting. Whatever redeeming traits or qualities it may possess, if any, shall be brought to light by subjecting it to other tests. It was our desire and intention to furnish a correct table of the gallon-measure products of the several States of the Union; but we have not been successful in our attempt to procure the necessary statistics. Enough is known, however, to satisfy us that the value of the milk, wine, ardent spirits, malt liquors, fluids, oils, and molasses, annually produced and sold in the free States, is at least fifty millions of dollars greater than the value of the same articles annually produced and sold in the slave States. Of sweet milk alone, it is estimated that the monthly sales in three Northern cities, New York, Philadelphia and Boston, amount to a larger sum than the marketable value of all the rosin, tar, pitch, and turpentine, annually produced in the Southern States.
