It emphasized not only the capacity of the American people for intelligent and orderly self-government, but also the strength and endurance of our popular forms. It was a profound surprise to those habituated to different political conditions. They had witnessed with astonishment the quiet disbandment of millions of men but as yesterday engaged in mortal strife--the vast armies as peacefully returning to former vocations as though from a great parade--and now, from a state of civil convulsion that in many another nation would have produced armed collision and public disorder, they saw an entire people quietly accepting the verdict of the highest authoritive body of the land, and practically dismissing the subject from thought. It was a splendid world-wide tribute to the strength and endurance of our system of popular government. Yet the conclusion must not be deduced that the power of impeachment is not a wise provision of our Constitution, nor in any sense inconsistent with our popular forms. Conditions may, and are not unlikely to arise, some day, when the exercise of the power to impeach and remove the President may be quite as essential to the preservation of our political system as it threatened to become in this instance destructive of that system. Should that day ever come, it is to be hoped that the remedy of impeachment, as established by the Constitution, may be as patriotically, as fearlessly, and as unselfishly applied as it was on this occasion rejected.
