people should be taught to regard them as their greatest interest, and as the first objects of their duty and affection. Maintained in their just rights and powers, they form the true balance-wheel, the only effectual check upon federal encroachments. And it possesses as a check these distinguishing advantages over every other, that it can never be applied without great deliberation and caution, that it is certain in its effects, and that it is but little liable to abuse. It is true that a State may use its power for improper purposes, or on improper occasions; but the federal government is, to say the least of it, equally liable to dangerous errors and violations of trust. Shall we then leave that government free from all restraint, merely because the proper countervailing power is liable to abuse? Upon the same principle, we should abandon all the guards and securities, which we have so carefully provided in the Federal Constitution itself. The truth is, all checks upon government are more or less imperfect; for if it were not so, government itself would be perfect. But this is no reason why we should abandon it to its own will. We have only to apply to this subject our [ *131 ]*best discretion and caution, to confer no more power than is absolutely necessary, and to guard that power as carefully as we can. Perfection is not to be hoped for; but an approximation to it, sufficiently near to afford a reasonable security to our rights and liberties, is not unattainable. In the formation of the federal government we have been careful to limit its powers, and define its duties. Our object was to render it such that the people should feel an interest in sustaining it in its purity, for otherwise it could not long subsist. Upon the same principle, we should enlist the same interest in the wise and proper application of those checks, which its unavoidable imperfections render necessary. That interest is found in the States. Having created the federal government at their own free will, and for their own uses, why should they seek to destroy it? Having clothed it with a certain portion of their own powers, for their own benefit alone, why should they desire to render those powers inoperative and nugatory? The danger is, not that the States will interpose too often, but that they will rather submit to federal usurpations, than incur the risk of embarrassing that government, by
