Kennedy wrote them out personal checks for their respective amounts, but dated them two days ahead to insure their staying. He threw off all disguise now and with authority from Norton directed the repairing of the machine. Fortunately it was in pretty good condition. The broken part was the skids, not the essential parts of the machine. As for the gyroscope, there were plenty of them and another dynamo, and it was a very simple thing to replace the old one that had been destroyed.
Sinclair worked with a will, far past his regular hours. Jaurette also worked, though one could hardly say with a will. In fact, most of the work was done by Sinclair and Kennedy, with Jaurette sullenly grumbling, mostly in French under his breath. I did not like the fellow and was suspicious of him. I thought I noticed that Kennedy did not allow him to do much of the work, either, though that may have been for the reason that Kennedy never asked anyone to help him who seemed unwilling.
"There," exclaimed Craig about ten o"clock. "If we want to get back to the city in any kind of time to-night we had better quit. Sinclair, I think you can finish repairing these skids in the morning."
We locked up the hangar and hurried across to the station. It was late when we arrived in New York, but Kennedy insisted on posting off up to his laboratory, leaving me to run down to the Star office to make sure that our story was all right for the morning papers.
I did not see him until morning, when a large touring-car drove up.
Kennedy routed me out of bed. In the tonneau of the car was a huge package carefully wrapped up.
"Something I worked on for a couple of hours last night," explained Craig, patting it. "If this doesn"t solve the problem then I"ll give it up."
I was burning with curiosity, but somehow, by a perverse a.s.sociation of ideas, I merely reproached Kennedy for not taking enough rest.
"Oh," he smiled. "If I hadn"t been working last night, Walter, I couldn"t have rested at all for thinking about it."
When we arrived at the field Norton was already there with his head bandaged. I thought him a little pale, but otherwise all right. Jaurette was sulking, but Sinclair had finished the repairs and was busily engaged in going over every bolt and wire. Humphreys had sent word that he had another offer and had not shown up.
"We must find him," exclaimed Kennedy. "I want him to make a flight to-day. His contract calls for it."
"I can do it, Kennedy," a.s.serted Norton. "See, I"m all right."
He picked up two pieces of wire and held them at arm"s length, bringing them together, tip to tip, in front of him just to show us how he could control his nerves.
"And I"ll be better yet by this afternoon," he added. "I can do that stunt with the points of pins then."
Kennedy shook his head gravely, but Norton insisted, and finally Kennedy agreed to give up wasting time trying to locate Humphreys. After that he and Norton had a long whispered conference in which Kennedy seemed to be unfolding a scheme.
"I understand," said Norton at length, "you want me to put this sheet-lead cover over the dynamo and battery first. Then you want me to take the cover off, and also to detach the gyroscope, and to fly without using it. Is that it?"
"Yes," a.s.sented Craig. "I will be on the roof of the grand stand. The signal will be three waves of my hat repeated till I see you get it."
After a quick luncheon we went up to our vantage-point. On the way Kennedy had spoken to the head of the Pinkertons engaged by the management for the meet, and had also dropped in to see the wireless operator to ask him to send up a messenger if he saw the same phenomena as he had observed the day before.
On the roof Kennedy took from his pocket a little instrument with a needle which trembled back and forth over a dial. It was nearing the time for the start of the day"s flying, and the aeroplanes were getting ready. Kennedy was calmly biting a cigar, casting occasional glances at the needle as it oscillated. Suddenly, as Williams rose in the Wright machine, the needle swung quickly and pointed straight at the aviation field, vibrating through a small area, back and forth.
"The operator is getting his apparatus ready to signal to Williams,"
remarked Craig. "This is an apparatus called an ondometer. It tells you the direction and something of the magnitude of the Hertzian waves used in wireless."
Five or ten minutes pa.s.sed. Norton was getting ready to fly. I could see through my field gla.s.s that he was putting something over his gyroscope and over the dynamo, but could not quite make out what it was. His machine seemed to leap up in the air as if eager to redeem itself.
Norton with his white-bandaged head was the hero of the hour. No sooner had his aeroplane got up over the level of the trees than I heard a quick exclamation from Craig.
"Look at the needle, Walter!" he cried. "As soon as Norton got into the air it shot around directly opposite to the wireless station, and now it is pointing--"
We raised our eyes in the direction which it indicated. It was precisely in line with the weather-beaten barn.
I gasped. What did it mean? Did it mean in some way another accident to Norton--perhaps fatal this time? Why had Kennedy allowed him to try it to-day when there was even a suspicion that some nameless terror was abroad in the air? Quickly I turned to see if Norton was all right. Yes, there he was, circling above us in a series of wide spirals, climbing up, up. Now he seemed almost to stop, to hover motionless. He was motionless. His engine had been cut out, and I could see his propeller stopped. He was riding as a ship rides on the ocean.
A boy ran up the ladder to the roof. Kennedy unfolded the note and shoved it into my hands. It was from the operator.
"Wireless out of business again. Curse that fellow who is b.u.t.ting in. Am keeping record," was all it said.
I shot a glance of inquiry at Kennedy, but he was paying no attention now to anything but Norton. He held his watch in his hand.
"Walter," he e.j.a.c.u.l.a.t.ed as he snapped it shut, "it has now been seven minutes and a half since he stopped his propeller. The Brooks Prize calls for five minutes only. Norton has exceeded it fifty per cent. Here goes."
With his hat in his hand he waved three times and stopped. Then he repeated the process.
At the third time the aeroplane seemed to give a start. The propeller began to revolve, Norton starting it on the compression successfully.
Slowly he circled down again. Toward the end of the descent he stopped the engine and volplaned, or coasted, to the ground, landing gently in front of his hangar.
A wild cheer rose into the air from the crowd below us. All eyes were riveted on the activity about Norton"s biplane. They were doing something to it. Whatever it was, it was finished in a minute and the men were standing again at a respectful distance from the propellers.
Again Norton was in the air. As he rose above the field Kennedy gave a last glance at his ondometer and sprang down the ladder. I followed closely. Back of the crowd he hurried, down the walk to the entrance near the railroad station. The man in charge of the Pinkertons was at the gate with two other men, apparently waiting.
"Come on!" shouted Craig.
We four followed him as fast as we could. He turned in at the lane running up to the yellow house, so as to approach the barn from the rear, un.o.bserved.
"Quietly, now," he cautioned.
We were now at the door of the barn. A curious crackling, snapping noise issued. Craig gently tried the door. It was bolted on the inside. As many of us as could threw ourselves like a human catapult against it. It yielded.
Inside I saw a sheet of flame fifteen or twenty feet long--it was a veritable artificial bolt of lightning. A man with a telescope had been peering out of the window, but now was facing us in surprise.
"Lamar," shouted Kennedy, drawing a pistol, "one motion of your hand and you are a dead man. Stand still where you are. You are caught red-handed."
The rest of us shrank back in momentary fear of the gigantic forces of nature which seemed let loose in the room. The thought, in my mind at least, was: Suppose this arch-fiend should turn his deadly power on us?
Kennedy saw us from the corner of his eye. "Don"t be afraid," he said with just a curl to his lip. "I"ve seen all this before. It won"t hurt you. It"s a high frequency current. The man has simply appropriated the invention of Mr. Nikola Tesla. Seize him. He won"t struggle. I"ve got him covered."
Two burly Pinkertons leaped forward gingerly into the midst of the electrical apparatus, and in less time than it takes to write it Lamar was hustled out to the doorway, each arm pinioned back of him.
As we stood, half dazed by the suddenness of the turn of events, Kennedy hastily explained:
"Tesla"s theory is that under certain conditions the atmosphere, which is normally a high insulator; a.s.sumes conducting properties and so becomes capable of conveying any amount of electrical energy. I myself have seen electrical oscillations such as these in this room of such intensity that while they could be circulated with impunity through one"s arms and chest they would melt wires farther along in the circuit. Yet the person through whom such a current is pa.s.sing feels no inconvenience. I have seen a loop of heavy copper wire energised by such oscillations and a ma.s.s of metal within the loop heated to the fusing point, and yet into the s.p.a.ce in which this destructive aerial turmoil was going on I have repeatedly thrust my hand and even my head, without feeling anything or experiencing any injurious after-effect. In this form all the energy of all the dynamos of Niagara could pa.s.s through one"s body and yet produce no injury. But, diabolically directed, this vast energy has been used by this man to melt the wires in the little dynamo that runs Norton"s gyroscope. That is all. Now to the aviation field. I have something more to show you."
We hurried as fast as we could up the street and straight out on the field, across toward the Norton hangar, the crowd gaping in wonderment.
Kennedy waved frantically for Norton to come down, and Norton, who was only a few hundred feet in the air, seemed to see and understand.
As we stood waiting before the hangar Kennedy could no longer restrain his impatience.
"I suspected some wireless-power trick when I found that the field wireless telegraph failed to work every time Norton"s aeroplane was in the air," he said, approaching close to Lamar. "I just happened to catch sight of that peculiar wireless mast of yours. A little flash of light first attracted my attention to it. I thought it was an electric spark, but you are too clever for that, Lamar. Still, you forgot a much simpler thing. It was the glint of the sun on the lens of your telescope as you were watching Norton that betrayed you."
Lamar said nothing.
"I"m glad to say you had no confederate in the hangar here," continued Craig. "At first I suspected it. Anyhow, you succeeded pretty well single handed, two lives lost and two machines wrecked. Norton flew all right yesterday when he left his gyroscope and dynamo behind, but when he took them along you were able to fuse the wires in the dynamo--you pretty nearly succeeded in adding his name to those of Browne and Herrick."
The whir of Norton"s machine told us he was approaching. We scattered to give him s.p.a.ce enough to choose the spot where he would alight. As the men caught his machine to steady it, he jumped lightly to the ground.
