In like manner, as a manifestly indispensable condition of the perpetuation of the Union and of the realization of that magnificent national future adverted to, does the duty become yearly stronger and clearer upon us, as citizens of the several States, to cultivate a fraternal and affectionate spirit, language, and conduct in regard to other States and in relation to the varied interests, institutions, and habits of sentiment and opinion which may respectively characterize them. Mutual forbearance, respect, and noninterference in our personal action as citizens and an enlarged exercise of the most liberal principles of comity in the public dealings of State with State, whether in legislation or in the execution of laws, are the means to perpetuate that confidence and fraternity the decay of which a mere political union, on so vast a scale, could not long survive. In still another point of view is an important practical duty suggested by this consideration of the magnitude of dimensions to which our political system, with its corresponding machinery of government, is so rapidly expanding. With increased vigilance does it require us to cultivate the cardinal virtues of public frugality and official integrity and purity. Public affairs ought to be so conducted that a settled conviction shall pervade the entire Union that nothing short of the highest tone and standard of public morality marks every part of the administration and legislation of the General Government. Thus will the federal system, whatever expansion time and progress may give it, continue more and more deeply rooted in the love and confidence of the people. That wise economy which is as far removed from parsimony as from corrupt and corrupting extravagance; that single regard for the public good which will frown upon all attempts to approach the Treasury with insidious projects of private interest cloaked under public pretexts; that sound fiscal administration which, in the legislative department, guards against the dangerous temptations incident to overflowing revenue, and, in the executive, maintains an unsleeping watchfulness against the tendency of all national expenditure to extravagance, while they are admitted elementary political duties, may, I trust, be deemed as properly adverted to and urged in view of the more impressive sense of that necessity which is directly suggested by the considerations now presented.
