Finally, Gentlemen, there was in the breast of Washington one sentiment so deeply felt, so constantly uppermost, that no proper occasion escaped without its utterance. From the letter which he signed in behalf of the Convention when the Constitution was sent out to the people, to the moment when he put his hand to that last paper in which he addressed his countrymen, the Union,--the Union was the great object of his thoughts. In that first letter he tells them that to him and his brethren of the Convention, union appears to be the greatest interest of every true American; and in that last paper he conjures them to regard that unity of government which constitutes them one people as the very palladium of their prosperity and safety, and the security of liberty itself. He regarded the union of these States less as one of our blessings, than as the great treasure-house which contained them all. Here, in his judgment, was the great magazine of all our means of prosperity; here as he thought, and as every true American still thinks, are deposited all our animating prospects, all our solid hopes for future greatness. He has taught us to maintain this union, not by seeking to enlarge the powers of the government, on the one hand, nor by surrendering them, on the other; but by an administration of them at once firm and moderate, pursuing objects truly national, and carried on in a spirit of justice and equity. _The American Nation Unique_ The extreme solicitude for the preservation of the Union, at all times manifested by him, shows not only the opinion he entertained of its importance, but his clear perception of those causes which were likely to spring up to endanger it, and which, if once they should overthrow the present system, would leave little hope of any future beneficial reunion. Of all the presumptions indulged by presumptuous men, that is one of the rashest which looks for repeated and favorable opportunities for the deliberate establishment of a united government over distinct and widely extended communities. Such a thing has happened once in human affairs, and but once; the event stands out as a prominent exception to all ordinary history; and unless we suppose ourselves running into an age of miracles, we may not expect its repetition.
