A deep sigh rose as if in unison all along the table. The event was too large for instant grasping. There was no applause at first. Some—many—did not understand. Not so certain others.

The minister from Great Britain, the minister from Spain, Aaron Burr and a few other men acquainted with great affairs, prominent in public life, turned and looked at the President’s tall figure at the head of the table, and then at that of the silent young man whom Mr. Jefferson had publicly honored.

The face of Aaron Burr grew pale. The faces of the foreign ministers showed sudden consternation. Theodosia Alston turned, her own eyes fixed upon the grave face of the young man sitting at her side, who made no sign of the strong emotion possessing his soul.

“I have given you my news,” the voice of Mr. Jefferson went on, rising now, vibrant and masterful, fearless, compelling. “There you have it, this little message, large as any ever written in the world. The title to that Western land has passed to us. We set our seal on it now! Cost what it may, we shall hold it so long as we can claim a flag or a country on this continent. The price is nothing. Fifteen millions means no more than the wine or water left in a half-empty glass. It might be fifty times fifteen millions, and yet not be one fiftieth enough. These things are not to be measured by known signs or marks of values. It is not in human comprehension to know what we have gained. Hence we have no human right to boast. The hand of Almighty God is in this affair! It was He who guided the fingers of those who signed this cession to the United States of America!

“My friends, now I am content. What remains is but detail. Our duty is plain. Between us and this purpose, I shall hold all intervention of whatever nature, friendly or hostile, as no more than details to be ignored. Yonder lies and has always lain the scene of my own ambition. Always I have hungered to know that vast new land beyond all maps, as yet ignorant of human metes and bounds. Always I have coveted it for this republic, knowing that without room for expansion we must fail, that with it we shall triumph to the edge of our ultimate dream of human destiny—triumph and flourish while governments shall remain known among men.

“I offer that faith to the eyes of the world today and of all the days to come, believing in every humility that God guided the hands of those who signed this title deed of a great empire, and that God long ago implanted in my unworthy bosom the strong belief that one day this might be which now has come to pass. It is no time for boasting, no time for any man to claim glory or credit for himself. We are in the face of events so vast that their margins leave our vision. We cannot see to the end of all this, cannot read all the purpose of it, because we are but men.

“Gentlemen, you Americans, men of heart, of courage! You also, ladies, who care most for gentlemen of heart and courage, whose pulses beat even with our own to the stimulus of our deeds! I say to you all that I would gladly lay aside my office and its honors—I would lay aside all my other ambitions, all my desires to be remembered as a man who at least endeavored to think and to act—if thereby I might lead this expedition of our volunteers for the discovery of the West. That may not be. These slackened sinews, these shrinking limbs, these fading eyes, do not suffice for such a task. It is in my heart, yes; but the heart for this magnificent adventure needs stronger pulses than my own.

“My heart—did I say that I had need of another, a better? Did I say that I had need of eyes and brains, of thews and sinews, of calm nerves and steady blood? Did I say I had need of courage and resolution—all these things combined? I have them! That Providence who has given us all needful instruments and agents to this point in our career as a republic has given us yet another, and the last one needful. Tomorrow my friend, my special messenger, Captain Meriwether Lewis, starts with his expedition. He will explore the country between the Missouri and the Pacific—the country of my dream and his. It is no longer the country of any other power—it is our own!

“Gentlemen, I give you a toast—Captain Meriwether Lewis!”
