the 50th time that we the people have celebrated this historic occasion. When the first President, George Washington, placed his hand upon the Bible, he stood less than a single day's journey by horseback from raw, untamed wilderness. There were 4 million Americans in a union of 13 States. Today we are 60 times as many in a union of 50 States. We have lighted the world with our inventions, gone to the aid of mankind wherever in the world there was a cry for help, journeyed to the Moon and safely returned. So much has changed. And yet we stand together as we did two centuries ago.
