The 4th of July is the first great fact in your nation's history — the very ring-bolt in the chain of your yet undeveloped destiny. Pride and patriotism, not less than gratitude, prompt you to celebrate and to hold it in perpetual remembrance. I have said that the Declaration of Independence is the ring-bolt to the chain of your nation's destiny; so, indeed, I regard it. The principles contained in that instrument are saving principles. Stand by those principles, be true to them on all occasions, in all places, against all foes, and at whatever cost.
