to the stability of such a federation as ours, covering as it does the greater part of a huge continent, it was absolutely indispensable. Thus, at length, was realized the sublime conception of a nation in which every citizen lives under two complete and well-rounded systems of laws,--the state law and the federal law,--each with its legislature, its executive, and its judiciary moving one within the other, noiselessly and without friction. It was one of the longest reaches of constructive statesmanship ever known in the world. There never was anything quite like it before, and in Europe it needs much explanation to-day even for educated statesmen who have never seen its workings. Yet to Americans it has become so much a matter of course that they, too, sometimes need to be told how much it signifies. In 1787 it was the substitution of law for violence between states that were partly sovereign. In some future still grander convention we trust the same thing will be done between states that have been wholly sovereign, whereby peace may gain and violence be diminished over other lands than this which has set the example. Great as was the work which the Federal Convention had now accomplished, none of the members supposed it to be complete. After some discussion, it was decided that Congress might at any time, by a two thirds vote in both houses, propose amendments to the constitution, or on the application of the legislatures of two thirds of the states might call a convention for proposing amendments; and such amendments should become part of the constitution as soon as ratified by three fourths of the states, either through their legislatures or through special conventions summoned for the purpose. The design of this elaborate arrangement was to guard against hasty or ill-considered changes in the fundamental instrument of government; and its effectiveness has been such that an amendment has come to be impossible save as the result of intense conviction on the part of a vast majority of the whole American people. Finally it was decided that the Federal Constitution, as now completed, should be presented to the Continental Congress, and then referred to special conventions in all the states for ratification; and that when nine states, or two thirds of the whole number, should have ratified, it should at once go into operation as between such ratifying states.
