"Yes," called back Norton. Reaching back of him, he pointed out the way to detach the gyroscope and put a sort of brake on it that stopped its revolutions almost instantly. "It's a ticklish job to change in the air," he shouted. "It can be done, but it's safer to land and do it."

The flight was soon over, and we stood admiring the machine while Norton expatiated on the compactness of his little dynamo.

"What have you done with the wrecks of the other machines?" inquired Kennedy at length.

"They are stored in a shed down near the railroad station. They are just a ma.s.s of junk, though there are some parts that I can use, so I'll ship them back to the factory."

"Might I have a look at them?"

"Surely. I'll give you the key. Sorry I can't go myself, but I want to be sure everything is all right for my flight this afternoon."

It was a long walk over to the shed near the station, and, together with our examination of the wrecked machines, it took us the rest of the morning. Craig carefully turned over the wreckage. It seemed a hopeless quest to me, but I fancied that to him it merely presented new problems for his deductive and scientific mind.

"These gyroscopes are out of business for good," he remarked as he glanced at the dented and battered aluminum cases. "But there doesn't seem to be anything wrong with them except what would naturally happen in such accidents."

For my part I felt a sort of awe at the ma.s.s of wreckage in which Browne and Herrick had been killed. It was to me more than a tangled ma.s.s of wires and splinters. Two human lives had been snuffed out in it.

"The engines are a ma.s.s of sc.r.a.p; see how the cylinders are bent and twisted," remarked Kennedy with great interest. "The gasoline-tank is intact, but dented out of shape. No explosion there. And look at this dynamo. Why, the wires in it are actually fused together. The insulation has been completely burned off. I wonder what could have caused that?"

Kennedy continued to regard the tangled ma.s.s thoughtfully for some time, then locked the door, and we strolled back to the grand stand on our side of the field. Already the crowd had begun to collect. Across the field we could see the various machines in front of their hangars with the men working on them. The buzz of the engines was wafted across by the light summer breeze as if a thousand cicadas had broken loose to predict warm weather.

Two machines were already in flight, a little yellow Demoiselle, scurrying around close to the earth like a frightened hen, and a Bleriot, high overhead, making slow and graceful turns like a huge bird.

Kennedy and I stopped before the little wireless telegraph station of the signal corps in front of the grand stand and watched the operator working over his instruments.

"There it is again," muttered the operator angrily.

"What's the matter?" asked Kennedy. "Amateurs interfering with you?"

The man nodded a reply, shaking his head with the telephone-like receiver, viciously. He continued to adjust his apparatus.

"Confound it!" he exclaimed. "Yes, that fellow has been jamming me for the past two days off and on, every time I get ready to send or receive a message. Williams is going up with a Wright machine equipped with wireless apparatus in a minute, and this fellow won't get out of the way. By Jove, though, those are powerful impulses of his. Hear that crackling? I've never been interfered with so in my experience. Touch that screen door with your knife."

Kennedy did so, and elicited large sparks with quite a tingle of a shock.

"Yesterday and the day before it was so bad we had to give up attempting to communicate with Williams," continued the operator. "It was worse than trying to work in a thunder-shower. That's the time we get our troubles, when the air is overcharged with electricity, as it is now."

"That's interesting," remarked Kennedy.

"Interesting?" flashed back the operator, angrily noting the condition in his "log book."

"Maybe it is, but I call it darned mean. It's almost like trying to work in a power station."

"Indeed?" queried Kennedy. "I beg your pardon--I was only looking at it from the purely scientific point of view. Who is it, do you suppose?"

"How do I know? Some amateur, I guess. No professional would b.u.t.t in this way."

Kennedy took a leaf out of his note-book and wrote a short message which he gave to a boy to deliver to Norton.

"Detach your gyroscope and dynamo," it read. "Leave them in the hangar.

Fly without them this afternoon, and see what happens. No use to try for the prize to-day. Kennedy."

We sauntered out on the open part of the field, back of the fence and to the side of the stands, and watched the fliers for a few moments. Three were in the air now, and I could see Norton and his men getting ready.

The boy with the message was going rapidly across the field. Kennedy was impatiently watching him. It was too far off to see just what they were doing, but as Norton seemed to get down out of his seat in the aeroplane when the boy arrived, and it was wheeled back into the shed, I gathered that he was detaching the gyroscope and was going to make the flight without it, as Kennedy had requested.

In a few minutes it was again wheeled out.

The crowd, which had been waiting especially to see Norton, applauded.

"Come, Walter," exclaimed Kennedy, "let's go up there on the roof of the stand where we can see better. There's a platform and railing, I see."

His pa.s.s allowed him to go anywhere on the field, so in a few moments we were up on the roof.

It was a fascinating vantage-point, and I was so deeply engrossed between watching the crowd below, the bird-men in the air, and the machines waiting across the field that I totally neglected to notice what Kennedy was doing. When I did, I saw that he had deliberately turned his back on the aviation field, and was anxiously, scanning the country back of us.

"What are you looking for?" I asked. "Turn around. I think Norton is just about to fly."

"Watch him then," answered Craig. "Tell me when he gets in the air."

Just then Norton's aeroplane rose gently from the field. A wild shout of applause came from the people below us, at the heroism of the man who dared to fly this new and apparently fated machine. It was succeeded by a breathless, deathly calm, as if after the first burst of enthusiasm the crowd had suddenly realised the danger of the intrepid aviator.

Would Norton add a third to the fatalities of the meet?

Suddenly Kennedy jerked my arm. "Walter, look over there across the road back of us--at the old weatherbeaten barn. I mean the one next to that yellow house. What do you see?"

"Nothing, except that on the peak of the roof there is a pole that looks like the short stub of a small wireless mast. I should say there was a boy connected with that barn, a boy who has read a book on wireless for beginners."

"Maybe," said Kennedy. "But is that all you see? Look up in the little window of the gable, the one with the closed shutter."

I looked carefully. "It seems to me that I saw a gleam of something bright at the top of the shutter, Craig," I ventured. "A spark or a flash."

"It must be a bright spark, for the sun is shining brightly," mused Craig.

"Oh, maybe it's the small boy with a looking-gla.s.s. I can remember when I used to get behind such a window and shine a gla.s.s into the darkened room of my neighbours across the street."

I had really said that half in raillery, for I was at a loss to account in any other way for the light, but I was surprised to see how eagerly Craig accepted it.

"Perhaps you are right, in a way," he a.s.sented. "I guess it isn't a spark, after all. Yes, it must be the reflection of the sun on a piece of gla.s.s--the angles are just about right for it. Anyhow it caught my eye. Still, I believe that barn will bear watching."

Whatever his suspicions, Craig kept them to himself, and descended.

At the same time Norton gently dropped back to earth in front of his hangar, not ten feet from the spot where he started. The applause was deafening, as the machine was again wheeled into the shed safely.

Kennedy and I pushed through the crowd to the wireless operator.

"How's she working?" inquired Craig.

"Rotten," replied the operator sullenly. "It was worse than ever about five minutes ago. It's much better now, almost normal again."
