At any rate, that day found me face to face with the half-human personality which the Judge had named the Sheik of Baalbec, and whose eye has cast an evil cloud upon my life. Of course I do not know whether you are familiar with the old Natural History Society and its musty exhibit. A controversy about a curator in 1873 had caused the formation of the new American Institution of Biology. A few old men continued thereafter to support the ancient Society by annual subscription, and when they died, one or two of them, acting from stubborn partizanship, left the museum tied up with trusts and legacies, preventing the sale of a valuable city property and yet not furnishing enough to keep the building in repair or dust the case containing "Beavers at Work." Finally the old museum, once the pride of the municipality, had come down to the disgraceful necessity of letting its lower floor to a ten-cent exhibition of respectable waxworks, the principal attraction of which was the automatic chessplayer, which a year before my visit had gained suddenly a reputation for playing at times with the skill of a fiend. I faced the mechanism that afternoon for the first time, little realizing the intimacy, if I may use the word, which was to spring up between it and me. The representation of a squatting Arab, robed in red Oriental swathes and with a chessboard fastened to its knees, sat cross-legged on a box-like structure. Upon dropping a coin into a slot in the flat top, two folding-doors in front of this box would open for a few moments, showing a glass-covered interior, which, as far as the back of the box, was filled with a tangle of wheels and pulleys, seeming to preclude the possibility that a human being could hide therein. As soon as these doors closed, a flat space in the chest of the Sheik opened, with a faint purr of machinery to expose internal organs of metal levers and gears. The effect of this last exposure was extraordinary, and in all the time I knew the Sheik, I never got over it. The moment this cavity in his chest opened, he was an impersonal piece of mechanism; the moment it closed, however, the soul, the personality of a living being returned, and it seemed to me that the brown, wax skin of his nodding head, the black hair of his pointed beard, the red of his curved, malicious lips, the whites of his eyes, which showed when he moved with a squeak of unoiled bearings in his neck, and even the jointed fingers of his hand, with which he moved the pawns in short, mechanical jerks about the board, all belonged to a human body, containing an individual intelligence.
