And suddenly he burst into a harsh, jangling laugh. "Air!" he cried exultantly, "An Air Trust! By God in Heaven, it can be! It shall be!--it must!" His mind, somewhat sluggish before he had taken the morphine, now was working clearly and accurately again, with that fateful and undeviating precision which had made him master of billions of dollars and uncounted millions of human lives; which had woven his network of possession all over the United States, Europe and Asia and even Africa; which had drawn, as into a spider's web, the world's railroads and steamship lines, its coal and copper and steel, its oil and grain and beef, its every need--save air! And now, keen on the track of this last great inspiration, the Billionaire strode to his revolving book-case, whirled it round and from its shelves jerked a thick volume, a smaller book and some pamphlets. "Let's have some facts!" said he, flinging them upon his desk, and seating himself before it in a costly chair of teak. "Once I get an outline of the facts and what I want to do, then my subordinates can carry out my plans. Before all, I must have facts!" For half an hour he thumbed his references, noting all the salient points mentally, without taking a single note; for, so long as the drug still acted, his brain was an instrument of unsurpassed keenness and accuracy. A sinister figure he made, as he sat there poring intently over the technical books before him, contrasting strangely with the beauty and the luxury of the office. On the mantel, over the fireplace of Carrara marble, ticked a Louis XIV clock, the price of which might have saved the lives of a thousand workingmen's children during the last summer's torment. Gold-woven tapestries from Rouen covered the walls, whereon hung etchings and rare prints. Old Flint's office, indeed, had more the air of an art gallery than a place where grim plots and deals innumerable had been put through, lawmakers corrupted past counting, and the destinies of nations bent beneath his corded, lean and nervous hand. And now, as the Billionaire sat there thinking, smiling a smile that boded no good to the world, the soft spring air that had inspired his great plan still swayed the silken curtains. Of a sudden, he slammed the big book shut, that he was studying, and rose to his feet with a hard laugh--the laugh that had presaged more than one calamity to mankind. Beneath the sweep of his mustache one caught the glint of a gold tooth, sharp and unpleasant. A moment he stood there, keen, eager, dominant, his hands gripping the edge of the desk till the big knuckles whitened. He seemed the embodiment of harsh and unrelenting Power--power over men and things, over their laws and institutions; power which, like Alexander's, sought only new worlds to conquer; power which found all metes and bounds too narrow.
