"You gentlemen all know the general theory of the invention," Halsey went on, again assuming the post of lecturer, which Rawn once more graciously surrendered to him, waving a hand largely in his direction as though in explanation to the others. "It's simply the attuning of a motor to the free electrical current in the air--the wireless idea, of course. You're posted on all this. Now, I've got some little things here which will show some of the applications of our idea. We'll make a little track, for a railway train, and we'll run its motor here with current of our own, simply by our receiver for the free current. "I've often thought of the applicability of our receivers to the use of automobiles. Any man could have one of these receivers in his own garage, and could charge his own machine as he liked. That's only one use of the idea. What is true regarding auto cars is true also of plows, wagons, nearly all farm machinery. One of these receivers which you could carry around under your arm would do the work of many men, of many horses. With this model here I can, as Mr. Ackerman and Mr. Standley will agree, burst that electric fan wide open, and with no wire attachment for any current whatever. And I think we can run this little train of cars." A sigh went around the table at these calm words. These grave, gray men looked intently, bending forward at the edge of the table as young Halsey completed his mechanical arrangements. "If this thing works," said the large, bearded man, leaning forward, "where does it leave railway transportation?" "It leaves it with us!" interrupted John Rawn. "With us absolutely!" "What's to hinder anybody from building all the railroads they want, and making all the cars they want, and taking all the power they want out of the air, as you say?" "Nothing in the world to prevent," said John Rawn, "except the solidarity of the railway men of this country. If we take you all in and if you all stand pat, what chance has any one else got, except through buying power of us? Of course, this thing would break us if used against us. But we don't propose to see it used that way. Our patents protect us." "Go on," said the bearded man. "Let's see the wheels go 'round." They saw as much, and more. Halsey's little car repeated its circuit about the long table again and again, tirelessly, operated by power taken from the unwired receiver. Where the receiver got its power Halsey explained in detail as he had done before. The thing was there to show for itself. As to the breadth of its application, these men needed no advice. They were accustomed to the look ahead, to the weighing of wide possibilities.
