The claims of power for the General Government upon each of these points certainly present matter of the deepest interest. The first is, however, of much the greatest importance, inasmuch as, in addition to the dangers of unequal and improvident expenditures of public moneys common to all, there is superadded to that the conflicting jurisdictions of the respective governments. Federal jurisdiction, at least to the extent I have stated, has been justly regarded by its advocates as necessarily appurtenant to the power in question, if that exists by the Constitution. That the most injurious conflicts would unavoidably arise between the respective jurisdictions of the State and Federal Governments in the absence of a constitutional provision marking out their respective boundaries can not be doubted. The local advantages to be obtained would induce the States to overlook in the beginning the dangers and difficulties to which they might ultimately be exposed. The powers exercised by the Federal Government would soon be regarded with jealousy by the State authorities, and originating as they must from implication or assumption, it would be impossible to affix to them certain and safe limits. Opportunities and temptations to the assumption of power incompatible with State sovereignty would be increased and those barriers which resist the tendency of our system toward consolidation greatly weakened. The officers and agents of the General Government might not always have the discretion to abstain from intermeddling with State concerns, and if they did they would not always escape the suspicion of having done so. Collisions and consequent irritations would spring up; that harmony which should ever exist between the General Government and each member of the Confederacy would be frequently interrupted; a spirit of contention would be engendered and the dangers of disunion greatly multiplied.
