If such be the conditions of unity, then surely it is not to be feared, because New England manufactures, the Middle States mine, the Western States farm, and the Southern States plant, that, therefore, they must needs be under separate and distinct governments. This very dissimilarity of soil, climate, occupation, and production enables the sections to contribute to each other's welfare, and is a condition of their unity. The heart, liver, lungs, stomach, brain, and nerves cannot dispense with each other in the vital economy; it is the very dependence of one special part upon another through the channels of circulation, that renders the superior animal organism so completely a unit. It cannot be repeated too often that it is not sameness of function, but heterogeneity of function, that unity requires. Hence, through the specialization of industries--one kind of manufactures here, and another there; mining in one locality, and farming in another; the growing of a certain product in one section, and the growing of a different product in a different section--all these, together with, the increasing facilities for correspondence and transportation, are preparing society for larger, more complete, and inevitable unity. There need be no fear of confirmed hostility of feeling between the North and South when the war is over, should it end in the reestablishment of the Union. Southern journalists say: 'If the North is successful in its mad scheme of conquest, we shall look upon ourselves as a subjugated people, and there never can be cordial union between the people of the two sections.'
