Good evening, my fellow Americans. First, I should like to express my gratitude to the radio and television networks for the opportunities they have given me over the years to bring reports and messages to our nation. My special thanks go to them for the opportunity of addressing you this evening. Three days from now, after half century in the service of our country, I shall lay down the responsibilities of office as, in traditional and solemn ceremony, the authority of the Presidency is vested in my successor. This evening, I come to you with a message of leave-taking and farewell, and to share a few final thoughts with you, my countrymen.
