"Damn those workmen!" he exclaimed, with sudden irritation, as a louder chattering of pneumatic riveters from the new building all at once clattered in at the window. "A free country, eh? And men are permitted to make _that_ kind of a racket when a fellow wants to sleep! By God, if I--" "Drop that, Wally, and get up!" commanded Flint. "There's no time for this kind of thing today. Herzog has just informed me his experiments have brought results. We're going down to Oakwood Heights to sea a few things for ourselves. And the quicker you get dressed and in your right mind, the better. Come along, I tell you!" "Still chasing sunbeams from cucumbers, eh?" drawled the magnate, inhaling cigarette smoke and blowing a thin cloud toward the wanton Bacchantes. He affected indifference, but his dull eyes brightened a trifle in his wan face, deep-lined by the savage dissipations of the previous night. "And you insist on dragging me out on the same fatuous errand?" "Don't be an ass!" snapped the Billionaire. "Get up and come along. The sooner we have this thing under way, the better." "All right, anything to oblige," conceded Waldron, inwardly stirred by an interest he took good care not to divulge in word or look. "Give me just time for a cold plunge, a few minutes with my masseur and my barber, a bite to eat and--" Flint laid hold on his partner and shook him roughly. "Move, you sluggard!" he commanded. And Tiger Waldron obeyed. Forty-five minutes later, the two financiers were speeding down the asphalt of the avenue at a good round clip. Flint's gleaming car formed one unit of the never-ending procession of motors which, day and night, year in and year out, spin unceasingly along the great, hard, splendid, cruel thoroughfare. "I tell you," Flint was asserting as they swung into Broadway, at Twenty-third Street, and headed for South Ferry, "I tell you, Wally, the thing is growing vaster and more potent every moment. The longer I look at it, the huger its possibilities loom up! With air under our control, as a source of manufacturing alone, we can pull down perfectly inconceivable fortunes. We shan't have to send anywhere for our raw material. It will come to us; it's everywhere. No cost for transportation, to begin with. "With oxygen, nitrogen and liquid air as products, think of the possibilities, will you? Not an ice-plant in the country could compete with us, in the refrigerating line. With liquid air, we could sweep that market clean. By installing it on our fruit cars and boats, and our beef cars, the saving effected in many ways would run to millions. The sale of nitrogen, for fertilizer, would net us billions. And, above all, the control of the world's air supply, for breathing, would make us the absolute, undisputed masters of mankind!
