The Skylark of Space - E. E. Smith (e book reading free txt) 📗

“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 nearby objects are not affected.

“Second: I have studied two of the borderline 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 borderline 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 borderline 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 the tail, was covering the ground in prodigious leaps and bounds; at the same time pulling himself up, hand over hand, to the bar in front of him. He
