"Now of St. Louis," I corrected. "Of St. Louis." Had I been the President himself, Colonel Burr's bow could not have been more considerate or his smile more winning. "If I missed the pleasure of an introduction to Dr. Robinson in New Orleans, it was not due to lack of desire on my part," he said. "Governor Claiborne and Mr. Daniel Clark alike spoke highly of your merits, sir." "That Colonel Burr should remember such chance remarks concerning an unknown young doctor is indeed a compliment," I replied. "You were pointed out to me, sir, at the dinner given you by Governor Claiborne. An urgent professional call compelled me to leave before I could obtain an introduction. But my misfortune in missing the honor of meeting you, alike in New Orleans and upon your subsequent visit to St. Louis, will now, I trust, be offset by the pleasure of your company as a fellow guest." "I had in mind that you would count yourself among the Western well-wishers of Colonel Burr," remarked Mr. Jefferson, eying me as I thought with a certain sharpness. "My idea for this dinner was a party whose members would share a common interest in Louisiana affairs." As he finished speaking, the President stepped past me toward the door by which I had entered. Colonel Burr promptly took his place, still smiling suavely, but keen-eyed as a hawk. "Sir," he asked, in a low and eager voice, "may I indeed count you among my Western friends?" It may have been the magnetism of the man, or possibly only the suddenness of the question, but I found myself answering without thought, "We are all your well-wishers, sir." He smiled and gave me a significant glance which I did not half understand and liked still less. The words were on my tongue's tip to correct his evident misconception of my hasty answer, when he, in turn, stepped past me, bowing and smiling. I turned about, and received my third surprise. The President and Mr. Burr were exchanging bows with my Spanish don of the mired carriage! Great as was my astonishment, I intercepted and unconsciously made mental note of the look of understanding which as I turned was passing between the don and Colonel Burr. The former flashed a glance of inquiry from myself to the President, who met it with his ungraceful but ready courtesy--"Don Pedro Vallois, Dr. John H. Robinson." "And my good friend, senor!" added Mr. Burr, with a warmth of tone that astonished me. Senor Vallois responded to my bow with one as punctiliously polite as it was haughty. There was no sign of recognition in his cold eyes. The opportunity was too tempting to forgo. "I trust, senor, that you were not again stalled, and have not been required to inhabit the centre of the avenue these past three days," I remarked. At this he gazed at me with more interest. No doubt my voice jogged his memory, for in a moment his eye kindled, and he grasped my hand with the heartiness of an Englishman. "_Por Dios!_ It is our _caballero_ of the mire!"
