out, Seaton might get into an accident on his motorcycle, and we could prove by the state of development of our plans that we discovered it long ago."
"Because developing the stuff is highly dangerous, as you have found out. Even Seaton wouldn't have been alive now if he hadn't had a lot of luck at the start. Then, too, it would take too much time. Seaton has already developed it—you see, I haven't been asleep and I know what he has done, just as well as you do—and why should we go through all that slow and dangerous experimental work when we can get their notes and plans as well as not? There is bound to be trouble anyway when we steal all their solution, even though they haven't missed this little bit of it yet, and it might as well come now as any other time. The Corporation is amply protected, and I am still a Government chemist. Nobody even suspects that I am in on this deal. I will never see you except after hours and in private, and will never come near your offices. We will be so cautious that, even if anyone should get suspicious, they can't possibly link us together, and until they do link us together, we are all safe. No, Brookings, a raid in force is the only sure and safe way. What is more natural than a burglary of a rich man's house? It will be a simple affair. The police will stir around for a few days, then it will all be forgotten and we can go ahead. Nobody will suspect anything except Crane, if he is alive, and he won't be able to do anything."
So the argument raged. Brookings was convinced that DuQuesne was right in wanting to get possession of all the solution, and also of the working notes and plans, but would not agree to the means suggested, holding out for quieter and more devious, but less actionable methods. Finally he ended the argument with a flat refusal to countenance the raid, and the scientist was forced to yield, although he declared that they would have to use his methods in the end, and that it would save time, money, and perhaps lives, if they were used first. Brookings then took from his pocket his wireless and called Perkins. He told him of the larger bottle of solution, instructing him to secure it and to bring back all plans, notes, and other material he could find which in any way pertained to the matter in hand. Then, after promising DuQuesne to keep him informed of developments, and giving him an instrument similar to the one he himself carried, Brookings took his leave.
Seaton had worked from early morning until late at night, but had rigorously kept his promise to Dorothy. He had slept seven or eight hours every night and had called upon her regularly, returning from the visits with ever-keener zest for his work.
Late in the afternoon, upon the day of the explosion, Seaton stepped into Crane's shop with a mass of notes in his hand.
"Well, Mart, I've got it—some of it, at least. The power is just what we figured it, so immensely large as to be beyond belief. I have found:
"First: That it is a practically irresistible pull along the axis of the treated wire or bar. It is apparently focused at infinity, as near-by objects are not affected.
"Second: I have studied two of the border-line regions of current we discussed. I have found that in one the power is liberated as a similar attractive force but is focused upon the first object in line with the axis of the bar. As long as the current is applied it remains focused upon that object, no matter what comes between. In the second border-line condition the power is liberated as a terrific repulsion.
"Third: That the copper is completely transformed into available energy, there being no heat whatever liberated.
"Fourth: Most important of all, that the X acts only as a catalyst for the copper and is not itself consumed, so that an infinitesimally thin coating is all that is required."
"You certainly have found out a great deal about it," replied Crane, who had been listening with the closest attention, a look of admiration upon his face. "You have all the essential facts right there. Now we can go ahead and put in the details which will finish up the plans completely. Also, one of those points solves my hardest problem, that of getting back to the earth after we lose sight of it. We can make a small bar in that border-line condition and focus it upon the earth, and we can use that repulsive property to ward off any meteorites which may come too close to us."
"That's right. I never thought of using those points for anything. I found them out incidentally, and merely mentioned them as interesting facts. I have a model of the main bar built, though, that will lift me into the air and pull me all around. Want to see it work?"
"I certainly do."
As they were going out to the landing field Shiro called to them and they turned back to the house, learning that Dorothy and her father had just arrived.
"Hello, boys!" Dorothy said, bestowing her radiant smile upon them both as Seaton seized her hand. "Dad and I came out to see that you were taking care of yourselves, and to see what you are doing. Are visitors allowed?"
"No," replied Seaton promptly. "All visitors are barred. Members of the firm and members of the family, however, are not classed as visitors."
"You came at the right time," said Crane, smiling. "Dick has just finished a model, and was about to demonstrate it to me when you arrived. Come with us and watch the...."
"I object," interrupted Seaton. "It is a highly undignified performance as yet, and...."
"Objection overruled," interposed the lawyer, decisively. "You are too young and impetuous to have any dignity; therefore, any performance not undignified would be impossible, a priori. The demonstration will proceed."
Laughing merrily, the four made their way to the testing shed, in front of which Seaton donned a heavy leather harness, buckled about his shoulders, body and legs; to which were attached numerous handles, switches, boxes and other pieces of apparatus. He snapped the switch which started the Tesla coil in the shed and pressed a button on an instrument in his hand, attached to his harness by a small steel cable. Instantly there was a creak of straining leather and he shot vertically into the air for perhaps a hundred feet, where he stopped and remained motionless for a few moments. Then the watchers saw him point his arm and dart in the direction in which he pointed. By merely pointing, apparently, he changed his direction at will; going up and down, forward and backward, describing circles and loops and figures of eight. After a few minutes of this display he descended, slowing up abruptly as he neared the ground and making an easy landing.
"There, oh beauteous lady and esteemed sirs," he began, with a low bow and a sweeping flourish—when there was a snap, and he was jerked sidewise off his feet. In bowing, his cumbersome harness had pressed the controlling switch and the instrument he held in his hand, which contained the power-plant, or bar, had torn itself loose from its buckle. Instead of being within easy reach of his hand it was over six feet away, and was dragging him helplessly after it, straight toward the high stone wall! But only momentarily was he helpless, his keen mind discovering a way out of the predicament even as he managed to scramble to his feet in spite of the rapid pace. Throwing his body sidewise and reaching out his long arm as far as possible toward the bar, he succeeded in swinging it around so that he was running back toward the party and the spacious landing field. Dorothy and her father were standing motionless, staring at Seaton; the former with terror in her eyes, the latter in blank amazement. Crane had darted to the switch controlling the coil, and was reaching for it when Seaton passed them.
"Don't touch that switch!" he yelled. "I'll catch that thing yet!"
At this evidence that Seaton still thought himself master of the situation, Crane began to laugh, though he still kept his hand near the controlling switch. Dorothy, relieved of her fear for her lover's safety, could not help but join him, so ludicrous were Seaton's antics. The bar was straight out in front of him, about five feet above the ground, going somewhat faster than a man could run. It turned now to the right, now to the left, as his weight was thrown to one side or the other. Seaton, dragged along like a small boy trying to hold a runaway calf by
