the Union, we are told.  The real danger to the Union will come when the encroachments of the Slave-Power and the concessions of the Trade-Power shall have made it a burden instead of a blessing.  The real avalanche to be dreaded, are we to expect it from the ever-gathering mass of ignorant brute force, with the irresponsibility of animals and the passions of men, which is one of the fatal necessities of slavery, or from the gradually increasing consciousness of the non-slaveholding population of the Slave States of the true cause of their material impoverishment and political inferiority?  From one or the other source its ruinous forces will be fed, but in either event it is not the Union that will be imperilled, but the privileged Order who on every occasion of a thwarted whim have menaced its disruption, and who will then find in it their only safety.

We believe that the “irrepressible conflict”—­for we accept Mr. Seward’s much-denounced phrase in all the breadth of meaning he ever meant to give it—­is to take place in the South itself; because the Slave-System is one of those fearful blunders in political economy which are sure, sooner or later, to work their own retribution.  The inevitable tendency of slavery is to concentrate in a few hands the soil, the capital, and the power of the countries where it exists, to reduce the non-slaveholding class to a continually lower and lower level of property, intelligence, and enterprise,—­their increase in numbers adding much to the economical hardship of their position and nothing to their political weight in the community.  There is no home-encouragement of varied agriculture,—­for the wants of a slave population are few in number and limited in kind; none of inland trade, for that is developed only by communities where education induces refinement, where facility of communication stimulates invention and variety of enterprise, where newspapers make every man’s improvement in tools, machinery, or culture of the soil an incitement to all, and bring all the thinkers of the world to teach in the cheap university of the people.  We do not, of course, mean to say that slaveholding states may not and do not produce fine men; but they fail, by the inherent vice of their constitution and its attendant consequences, to create enlightened, powerful, and advancing communities of men, which is the true object of all political organizations, and which is essential to the prolonged existence of all those whose life and spirit are derived directly from the people.  Every man who has dispassionately endeavored to enlighten himself in the matter cannot but see, that, for the many, the course of things in slaveholding states is substantially what we have described, a downward one, more or less rapid, in civilization and in all those results of material prosperity which in a free country show themselves in the general advancement for the good of all and give a real meaning to the word Commonwealth.  No matter how enormous the
