When the several states of America became independent they called themselves the "United States of America"-- a very happy idea.

The Union was originally composed of thirteen states, covering about 300,000 square miles; it is now composed of forty-eight states and three territories, which in area amount to 3,571,492 square miles, practically as large in extent as China, the oldest nation in the world.

It should be noted that the name is most comprehensive: it might comprise the entire continent of North and South America.

It is safe to say that the founders of the nation did not choose such a name without consideration, and doubtless the designation "United States of America" conceals a deep motive.

I once asked a gentleman who said he was an American whether he had come from South or North America, or whether he was a Mexican, a Peruvian or a native of any of the countries in Central America?
He replied with emphasis that he was an American citizen of the United States.
