That the people and the States should, for a sufficient period of time, elect an uninterupted succession of men ready to betray both; that the traitors should, throughout this period, uniformly and systematically pursue some fixed plan for the extension of the military establishment; that the governments and the people of the States should silently and patiently behold the gathering storm, and continue to supply the materials, until it should be prepared to burst on their own heads, must appear to every one more like the incoherent dreams of a delirious jealousy, or the misjudged exaggerations of a counterfeit zeal, than like the sober apprehensions of genuine patriotism.
