Unhappily there was some foundation for this view of the case; and in this lies the root of the discontent of the South and its dissatisfaction with the Union, although it may break out upon another point. It is in this belief of an incompatibility of interest, from the perverted working of the federal government, that lies the root of southern discontent, and which constitutes the danger to the Union, and which statesmen should confront and grapple with; and not in any danger to slave property, which has continued to aggrandize in value during the whole period of the cry of danger, and is now of greater price than ever was known before; and such as our ancestors would have deemed fabulous. The sagacious Mr. Madison knew this--knew where the danger to the Union lay, when, in the 86th year of his age, and the last of his life, and under the anguish of painful misgivings, he wrote (what is more fully set out in the previous volume of this work) these portentous words: "_The visible susceptibility to the contagion of nullification in the Southern States, the sympathy arising from known causes, and the inculcated impression of a permanent incompatibility of interest between the North and the South, may put it in the power of popular leaders, aspiring to the highest stations, to unite the South, on some critical occasion, in some course of action of which nullification may be the first step, secession the second, and a farewell separation the last._" So viewed the evil, and in his last days, the great surviving founder of the Union--seeing, as he did, in this inculcated impression of a permanent incompatibility of interest between the two sections, the fulcrum or point of support, on which disunion could rest its lever, and parricidal hands build its schemes. What has been published in the South and adverted to in this View goes to show that an incompatibility of interest between the two sections, though not inherent, has been produced by the working of the government--not its fair and legitimate, but its perverted and unequal working.
