Our first meeting was curiously disturbing. He appeared suddenly at a door of my ateliers on the flying ground at Mineola, very tall, very soigné, smiling in the way he had that showed all his strong, square teeth as he recognized me in conversation, with my faithful mechanician, Georges. This latter, grown portly and nervous since marrying a Montmartre shopkeeper, I have since promoted to be my chief designer.

"Pardon the intrusion," said the stranger. "I perceive you are about to murder the stout gentleman. I will wait your convenience."

"Quite on the contrary, monsieur," I explained, bowing. "We discuss merely the theory of the explosion turbine. If monsieur will give himself the trouble to enter—"

"That is my card," he replied, advancing. "I want a strong, swift biplane, and a mechanic to attend to it."

I glanced from the card to this extraordinary young man with interest. For the name itself, John Hamlin Power, told me of a career in Wall Street—brief, but conspicuous in its daring and success; a career in which this immaculate, smiling young cotillion leader had made the very monarchs of finance fear the élan of his attack, the relentless quality of his grip.

"I have taken a fancy," he went on, "to possess the identical machine with which you accomplished your recent Mount McKinley record. It is perhaps for sale?"

"Perfectly, if monsieur wishes," I responded, with another bow. "But it is a machine of unusual speed and power. Monsieur can already fly, no doubt?"

"I do not anticipate any difficulty. As a matter of fact, I have not yet attempted it. It is for that purpose that I have come to buy a machine. It would be a favor if you would arrange to deliver it to me in Westchester to-morrow. The mechanic will, of course, arrive at the same time, as I shall wish to commence practice at once."

He turned aside to inspect a motor that lay dismounted on a wooden stand, as if there were nothing further to discuss. Indeed, though his speech was rapid and incisive, and his every movement full of an allure that spoke of splendidly poised muscles, he was in face and manner alike the most singularly immobile man I had ever met. He gave the impression of employing neither words nor actions except in case of clear necessity.

I exchanged glances with Georges, who had turned up his eyes, spread his arms, and allowed them to fall again limply to his sides. I coughed. Monsieur Power drew himself up from his inspection of the motor and smiled again expectantly.
