along. Come with me and I'll show you our flyer."

The flyer proved to be of the same general type as had been used by Hadley. It was equipped with six rocket motors, four discharging to the bow and two to the stern. Any one of them, Carpenter said, was ample for motive power. Equilibrium was maintained by means of a heavy gyroscope which would prevent any turning of the axis of its rotation. The entire flyer shell could be revolved about the axis so that oblique motion with our bow and stern motors was readily possible. Direct lateral movement was provided for by valves which would divert a portion of the discharge of either a bow or stern motor out through side vents in any direction. The motive power, of course, was furnished by the atomic disintegration of powdered aluminum. The whole interior, except for the portion of the walls, roof and floor, which was taken up by vitriolene windows, was heavily padded.

At nine the next morning the gates to the enclosure were thrown open and the representatives of the press admitted. Jim Carpenter mounted a platform and explained briefly what he proposed to do and then broke the crowd up into small groups and sent them over the works with guides. When all had been taken around they were reassembled and Carpenter announced to them his intention of going up in a space flyer and prove, by going through the heaviside layer, that he had actually destroyed a portion of it. There was an immediate clamor of applications to go with him. He laughingly announced that one reporter was all that he could stand on the ship and that he was taking one of his former associates with him. I could tell by the envious looks with which I was favored that any popularity I had ever had among my associates was gone forever. There was little time to think of such things, however, for the hour for our departure was approaching, and the photographers were clamoring for pictures of us and the flyer.

We satisfied them at last, and I entered the flyer after Carpenter. We sealed the car up, started the air conditioner, and were ready for departure.

"Scared, Pete?" asked Carpenter, his hand on the starting lever.

I gulped a little as I looked at him. He was perfectly calm to a casual inspection, but I knew him well enough to interpret the small spots of red which appeared on his high cheekbones and the glitter in his eye. He may not have been as frightened as I was but he was laboring under an enormous nervous strain. The mere fact that he called me "Pete" instead of his usual "First Mortgage" showed that he was feeling pretty serious.

"Not exactly scared," I replied, "but rather uneasy, so to speak."

He laughed nervously.

"Cheer up, old man! If anything goes wrong, we won't know it. Sit down and get comfortable; this thing will start with a jerk."

He pulled the starting lever forward suddenly and I felt as though an intolerable weight were pressed against me, glueing me to my seat. The feeling lasted only for a moment, for he quickly eased up on the motor, and in a few moments I felt quite normal.

"How fast are we going?" I asked.

"Only two hundred miles an hour," he replied. "We will reach the layer in plenty of time at this rate and I don't want to jam into it. You can get up now."

I rose, moved over to the observation glass in the floor, and looked down. We were already five or ten miles above the earth and were ascending rapidly. I could still detect the great circle of reflectors with which our way was to be opened.

"How can you tell where these heat beams are when they are turned on?" I asked. "Infra-red rays are not visible, and we will soon be out of sight of the reflectors."

"I forgot to mention that I am having a small portion of visible red rays mixed with the infra-red so that we can spot them. I have a radio telephone here, working on my private wavelength, so that I can direct operations from here as well as from the ground—in fact, better. If you're cold, turn on the heater."

The friction of the flyer against the air had so far made up for the decreasing temperature of the air surrounding us, but a glance at the outside thermometer warned me that his suggestion was a wise one. I turned a valve which diverted a small portion of our exhaust through a heating coil in the flyer. It was hard to realize that I was actually in a rocket space ship, the second one to be flown and that, with the exception of the ill-fated Hadley, farther from the earth than any man had been before. There was no sensation of movement in that hermetically sealed flyer, and, after the first few moments, the steady drone of the rocket motor failed to register on my senses. I was surprised to see that there was no trail of detritus behind us.

"You can see our trail at night," replied Carpenter when I asked him about it, "but in daylight, there is nothing to see. The slight luminosity of the gasses is hidden by the sun's rays. We may be able to see it when we get out in space beyond the layer, but I don't know. We have arrived at the bottom of the layer now, I believe. At any rate, we are losing velocity."

I moved over to the instrument board and looked. Our speed had dropped to one hundred and ten miles an hour and was steadily falling off. Carpenter pulled the control lever and reduced our power. Gradually the flyer came to a stop and hung poised in space. He shut off the power an instant and at once our indicator showed that we were falling, although very slowly. He promptly reapplied the power, and by careful adjustment brought us again to a dead stop.

"Ready to go," he remarked looking at his watch, "and just on time, too. Take a glass and watch the ground. I am going to have the heat turned on."

I took the binoculars he indicated and turned them toward the ground while he gave a few crisp orders into his telephone. Presently from the ground beneath us burst out a circle of red dots from which long beams stabbed up into the heavens. The beams converged as they mounted until at a point slightly below us, and a half-mile away they became one solid beam of red. One peculiarity I noticed was that, while they were plainly visible near the ground, they faded out, and it was not until they were a few miles below us that they again became apparent. I followed their path upward into the heavens.

"Look here, Jim!" I cried as I did so. "Something's happening!"

He sprang to my side and glanced at the beam.

"Hurrah!" he shouted, pounding me on the back. "I was right! Look! And the fools called it a magnetic field!"

Upward the beam was boring its way, but it was almost concealed by a rain of fine particles of black which were falling around it.

"It's even more spectacular than I had hoped," he chortled. "I had expected to reduce the layer to such fluidity that we could penetrate it or even to vaporize it, but we are actually destroying it! That stuff is soot and is proof, if proof be needed, that the layer is an organic liquid."

He turned to his telephone and communicated the momentous news to the earth and then rejoined me at the window. For ten minutes we watched and a slight diminution of the black cloud became apparent.

"They're through the layer," exclaimed Carpenter. "Now watch, and you'll see something. I'm going to start spreading the beam."

He turned again to his telephone, and presently the beam began to widen and spread out. As it did so the dark cloud became more dense than it had been before. The earth below us was hidden and we could see the red only as a dim murky glow through the falling soot. Carpenter inquired of the laboratory and found
