Such has been our political and current party history, and from the nature and necessities of things, every “extension of slavery,” or every expansion of territory, must in the future, as it has in the past, strengthen the cause of the producing classes, and give greater scope and power to the American idea of government. The acquisition of Louisiana, of Florida, of Texas, etc., of those great producing States on the Gulf Coast, has nearly overwhelmed the anti-republican tendencies of the North, and rendered almost powerless those combinations of capital and speculation which have always endangered the purity and simplicity of our republican system, and thus the rights and safety of the laboring and producing millions everywhere. Indeed, it is a truth, a simple fact, that can not be too often repeated, that in precise proportion to the amount or extent of so-called “slaveholding”—of the number of negroes in their normal condition—is freedom rendered secure to the white millions of the North. And when in the progress of time Cuba and Central America, and the whole tropical center of the continent is added to the Union and placed in the same relation to New York and Ohio that Mississippi, Alabama, etc., are now, then it is evident that the democratic or American idea of government will be securely established forever, and the rights and interests of the producing millions who ask nothing from government but its protection, will be no longer endangered by those anti-republican tendencies which in the North have so long conflicted with the natural development of our system, and struggled so long and fiercely against its existence. If this freedom and prosperity of the white man rested on wrong or oppression of the negro, then it would be valueless, for the Almighty has evidently designed that all His creatures should be permitted to live out the life to which He has adapted them. But when all the facts are considered, and the negro population of the South contrasted with any similar number of their race now or at any other time in human experience, then it is seen that, relatively considered, they are, perhaps, benefited to even a greater extent than the white population themselves. The efforts, as has been shown, to reverse the natural order of things—to force the negro into the position of the white man—are not merely failures, but frightful cruelties—cruelties that among ourselves end in the extinction of these poor creatures, while in the tropics it destroys the white man and impels the negro into barbarism.
