On April 19, 1975, as a crowd estimated at 110,000 gathered to view a parade and celebrate the Bicentennial in Concord, President Gerald Ford delivered a major speech near the North Bridge, which was televised to the nation . </P> <P> Freedom was nourished in American soil because the principles of the Declaration of Independence flourished in our land . These principles, when enunciated 200 years ago, were a dream, not a reality . Today, they are real . Equality has matured in America . Our inalienable rights have become even more sacred . There is no government in our land without consent of the governed . Many other lands have freely accepted the principles of liberty and freedom in the Declaration of Independence and fashioned their own independent republics . It is these principles, freely taken and freely shared, that have revolutionized the world . The volley fired here at Concord two centuries ago,' the shot heard round the world', still echoes today on this anniversary . </P>
