This, I think, will be news to many non-slaveholders in the gentleman's district. Thomas Jefferson tells us that man is an imitative animal; therefore, if the assertion of the gentleman from Mississippi be correct, we must wonder why slaveholders do not relieve themselves of their negroes, that they may become equally noble, proud, prosperous, and elevated, with the non-slaveholder. Who can compare with them on this side of Paradise? With them, the millennium can be no object of desire, since "Not a wave of trouble rolls Across their peaceful breasts." Still there must be some malice in their hearts, for the honorable gentleman states that they (the non-slaveholders) hold slavery in the hollow of their hands; surely, were they benevolent, they would close their hands and crush out the "institution," that their slaveholding fellow-citizens might become as prosperous and as happy as themselves. The assertion is frequently made, that white men cannot work in the hot latitudes of the South, and this is offered as a reason why there should be black slaves there. The gentleman knocks one of the strongest props from under the institution. He tells us white men work, and raise not only cotton, but corn and potatoes. He also informs us that after the cotton, corn, and potatoes, are raised, the strong, brave man drives the plow through the fallow ground. It will be seen that work during the summer has not produced the lassitude and enervation that it has been claimed is produced in white men by labor. We are still further informed, that the fallow ground turned up by the strong, brave man, discloses something more valuable than the gold of California--"'Tis the sparkles of liberty!" We have heard of the sparkles of liberty that are made manifest to the non-slaveholders of the South. The poor laboring man at Columbia, South Carolina, when streams of blood issued from the furrows plowed in his naked back by a cow-hide in the hands of a negro, saw some of the sparkles of liberty, when, bleeding, exhausted, besmeared with tar, and covered with feathers, he was thrust into the cars, and left to perish in the cold. He had, no doubt, a vivid idea of the liberty that is enjoyed by non-slaveholders in the South, when he remembered that these cruelties and barbarities were inflicted on him for expressing a rational and honest opinion relative to this "peculiar institution." The statements, and doubtless convictions, of the honorable member from Mississippi, differ singularly from those of Senator CLAY, of Alabama, who tells us that, in his State, "we may behold numerous fine houses, once the abode of intelligent freemen, now occupied by slaves, or else tenantless and dilapidated; that we may see fields, once fertile, covered with foxtail and broom-sedge--moss growing on the walls of once thrifty villages, and may find that 'one only master grasps the whole domain' which once furnished homes for a dozen white families."
