Hints United States Old World
The United States is at once a very new nation and a very old nation. It is a new nation compared with many other countries, and it is new, too, in the sense that it is constantly being renewed by the addition of new elements of population and of new States. But in other senses it is old. It is the oldest of the "new" nations--the first one to be made out of an Old World colony. It has the oldest written constitution, the oldest continuous federal system, and the oldest practice of self-government of any nation.
