The people of the North seem to have forgotten the warning of the Father of his Country against geographical parties. And by far the most dangerous of all such parties is that of a combined North against a combined South on the question of slavery. This is no mere political question—no question addressing itself to the material interests of men. It rises far higher. With the South it is a question of self-preservation, of personal security around the family altar, of life or of death. The Southern people still cherish a love for the Union; but what to them is even our blessed confederacy, the wisest and the best form of government ever devised by man, if they cannot enjoy its blessings and its benefits without being in constant alarm for their wives and children. The storm of abolition against the South has been gathering for almost a quarter of a century. It had been increasing by every various form of agitation which fanaticism could devise. We had reached the crisis. The danger was imminent. Republicanism was sweeping over the North like a tornado. It appeared to be resistless in its course. The blessed Union of these States—the last hope for human liberty on earth—appeared to be tottering on its base. Had Pennsylvania yielded, had she become an abolition State, without a special interposition of Divine Providence, we should have been precipitated into the yawning gulf of dissolution. But she stood erect and firm as her own Alleghanies. She breasted the storm and drove it back. The night is departing, and the roseate and propitious morn now breaking upon us promises a long day of peace and prosperity for our country. To secure this, all we of the North have to do is to permit our Southern neighbors to manage their own domestic affairs, as they permit us to manage ours. It is merely to adopt the golden rule, and do unto them as we would they should do unto us, in the like circumstances. All they ask from us is simply to let them alone. This is the whole spirit and essence of the much abused Cincinnati platform. This does no more than adopt the doctrine which is the very root of all our institutions, and recognize the right of a majority of the people of a Territory, when about to enter the Union as a State, to decide for themselves whether domestic slavery shall or shall not exist among them. This is not to favor the extension of slavery, but simply to deny the right of an abolitionist in Massachusetts or Vermont to prescribe to the people of Kansas what they shall or shall not do in regard to this question.
