As we see our ruinous system of commerce exemplified in the family of our Southern "gentleman," so we may see it exemplified, to a greater or less degree, in almost every other family throughout the length and breadth of the slaveholding States. We are all constantly buying, and selling, and wearing, and using Northern merchandise, at a double expense to both ourselves and our neighbors. If we but look at ourselves attentively, we shall find that we are all clothed _cap a pie_ in Northern habilaments. Our hats, our caps, our cravats, our coats, our vests, our pants, our gloves, our boots, our shoes, our under-garments--all come from the North; whence, too, Southern ladies procure all their bonnets, plumes, and flowers; dresses, shawls, and scarfs; frills, ribbons, and ruffles; cuffs, capes, and collars. True it is that the South has wonderful powers of endurance and recuperation; but she cannot forever support the reckless prodigality of her sons. We are all spendthrifts; some of us should become financiers. We must learn to take care of our money; we should withhold it from the North, and open avenues for its circulation at home. We should not run to New-York, to Philadelphia, to Boston, to Cincinnati, or to any other Northern city, every time we want a shoe-string or a bedstead, a fish-hook or a hand-saw, a tooth-pick or a cotton-gin. In ease and luxury we have been lolling long enough; we should now bestir ourselves, and keep pace with the progress of the age. We must expand our energies, and acquire habits of enterprise and industry; we should arouse ourselves from the couch of lassitude, and inure our minds to thought and our bodies to action. We must begin to feed on a more substantial diet than that of pro-slavery politics; we should leave off our siestas and post-meridian naps, and employ our time in profitable vocations. Before us there is a vast work to be accomplished--a work which has been accumulating on our hands for many years. It is no less a work than that of infusing the spirit of liberty into all our systems of commerce, agriculture, manufactures, government, literature, and religion. Oligarchal despotism must be overthrown; slavery must be abolished. For the purpose of showing how absolutely Southern "gentlemen," particularly slaveholding merchants, are lost to all sense of true honor and patriotism, we will here introduce an extract from an article which appeared more than three years ago in one of the editorial columns of the leading daily newspaper of the city of New-York. It is in these words:--
