Speech on the 150th anniversary of the signing of the Declaration of Independence

The following are excerpts from a 1926 speech by President Calvin Coolidge in honor of 150th anniversary of the signing of the Declaration of Independence:
We meet to celebrate the birthday of America. That coming of a new life always excites our interest. Although we know in the case of the individual that it has been an infinite repetition reaching back beyond our vision, that only makes it more wonderful. But how our interest and wonder increase when we behold the miracle of the birth of a new nation. It is to pay our tribute of reverence and respect to those who participated in such a mighty event that we annually observe the 4th day of July. Whatever may have been the impression created by the news which went out from this city on that summer day in 1776, there can be no doubt as to the estimate which is now placed upon it. At the end of 150 years the four corners of the earth unite in coming to Philadelphia as to a holy shrine in grateful acknowledgment of a service so great, which a few inspired men here rendered to humanity, that it is still the preeminent support of free government throughout the world.
