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 s.p.a.ce. 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 gla.s.s 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 that we were completely invisible to the ground, half the heavens being hidden by the black pall. For an hour the beam worked its way toward us.

"The hole is about four hundred yards in diameter right now," said Carpenter as he turned from the telephone. "I have told them to stop the movement of the reflectors, and as soon as the air clears a little, we'll start through."

It took another hour for the soot to clear enough that we could plainly detect the ring of red light before us. Carpenter gave some orders to the ground, and a gap thirty yards wide opened in the wall before us.

Toward this gap the flyer moved slowly under the side thrust of the diverted motor discharge. The temperature rose rapidly as we neared the wall of red light before us. Nearer we drew until the light was on both sides of us. Another few feet and the flyer shot forward with a jerk that threw me sprawling on the floor. Carpenter fell too, but he maintained his hold on the controls and tore at them desperately to check us.

I scrambled to my feet and watched. The red wall was alarmingly close.

Nearer we drove and then came another jerk which threw me sprawling again. The wall retreated. In another moment we were standing still, with the red all around us at a distance of about two hundred yards.

"We had a narrow escape from being cremated," said Carpenter with a shaky laugh. "I knew that our speed would increase as soon as we got clear of the layer but it caught me by surprise just the same. I had no idea how great the holding effect of the stuff was. Well, First Mortgage, the road to s.p.a.ce is open for us. May I invite you to be my guest on a little week-end jaunt to the Moon?"

"No thanks, Jim," I said with a wry smile. "I think a little trip to the edge of the layer will quite satisfy me."

"Quitter," he laughed. "Well, say good-by to familiar things. Here we go!"

He turned to the controls of the flyer, and presently we were moving again, this time directly away from the earth. There was no jerk at starting this time, merely a feeling as though the floor were pressing against my feet, a great deal like the feeling a person gets when they rise rapidly in an express elevator. The indicator showed that we were traveling only sixty miles an hour. For half an hour we continued monotonously on our way with nothing to divert us. Carpenter yawned.

"Now that it's all over, I feel let down and sleepy," he announced. "We are well beyond the point to which Hadley penetrated and so far we have met with no resistance. We are probably nearly at the outer edge of the layer. I think I'll shoot up a few miles more and then call it a day and go home. We are about eighty miles from the earth now."

I looked down, but could see nothing below us but the dense cloud of black soot resulting from the destruction of the heaviside layer. Like Carpenter, I felt sleepy, and I suppressed a yawn as I turned again to the window.

"Look here, Jim!" I cried suddenly. "What's that?"

He moved in a leisurely manner to my side and looked out. As he did so I felt his hand tighten on my shoulder with a desperate grip. Down the wall of red which surrounded us was coming an object of some kind. The thing was fully seventy-five yards long and half as wide at its main portion, while long irregular streams extended for a hundred yards on each side of it. There seemed to be dozens of them.

"What is it, Jim?" I asked in a voice which sounded high and unnatural to me.

"I don't know," he muttered, half to me and half to himself. "Good Lord, there's another of them!"

He pointed. Not far from the first of the things came another, even larger than the first. They were moving sluggishly along the red light, seeming to flow rather than to crawl. I had a horrible feeling that they were alive and malignant. Carpenter stepped back to the controls of the flyer and stopped our movement; we hung in s.p.a.ce, watching them. The things were almost level with us, but their sluggish movement was downward toward the earth. In color, they were a brilliant crimson, deepening into purple near the center. Just as the first of them came opposite us it paused, and slowly a portion of the ma.s.s extended itself from the main bulk; and then, like doors opening, four huge eyes, each of them twenty feet in diameter, opened and stared at us.

"It's alive, Jim," I quavered. I hardly knew my own voice as I spoke.

Jim stepped back to the controls with a white face, and slowly we moved closer to the ma.s.s. As we approached I thought that I could detect a fleeting pa.s.sage of expression in those huge eyes. Then they disappeared and only a huge crimson and purple blob lay before us. Jim moved the controls again and the flyer came to a stop.

Two long streamers moved out from the ma.s.s. Suddenly there was a jerk to the ship which threw us both to the floor. It started upward at express train speed. Jim staggered to his feet, grasped the controls and started all four bow motors at full capacity, but even this enormous force had not the slightest effect in diminishing our speed.

"Well, the thing's got us, whatever it is," said Jim as he pulled his controls to neutral, shutting off all power. Now that the danger had a.s.sumed a tangible form, he appeared as cool and collected as ever, to my surprise, I found that I had recovered control of my muscle and of my voice. I became aware that the shoulder which Jim had gripped was aching badly, and I rubbed it absently.

"What is it, Jim?" I asked for the third time.

"I don't know," he replied. "It is some horrible inhabitant of s.p.a.ce, something unknown to us on earth. From its appearance and actions, I think it must be a huge single-celled animal of the type of the earthly amoeba. If an amoeba is that large here, what must an elephant look like? However, I expect that we'll learn more about the matter later because it's taking us with it, wherever it's going."

Suddenly the flyer became dark inside. I looked at the nearest window, but I could not even detect its outline. I reached for the light switch, but a sudden change in direction threw me against the wall. There was an instant of intense heat in the flyer.

"We have pa.s.sed the heaviside layer," said Jim. "The brute has changed direction, and we felt that heat when he took us through the infra-red wall."

I reached again for the light switch, but before I could find it our motion ceased and an instant later the flyer was filled with glaring sunlight. We both turned to the window.

We lay on a glistening plain of bluish hue which stretched without a break as far as we could see. Not a thing broke the monotony of our vision. We turned to the opposite window. How can I describe the sight which met our horrified gaze? On the plain before us lay a huge purple monstrosity of gargantuan dimensions. The thing was a shapeless ma.s.s, only the four huge eyes standing out regarding us balefully. The ma.s.s was continually changing its outline and, as we watched, a long streamer extended itself from the body toward us. Over and around the flyer the feeler went, while green and red colors played over first one and then another of the huge eyes before us. The feeler wrapped itself around the flyer and we were lifted into the air toward those horrible eyes. We had almost reached them when the thing dropped us. We fell to the plain with a crash. We staggered to our feet again and looked out. Our captor was battling for its life.

Its attacker was a smaller thing of a brilliant green hue, striped and mottled with blue and yellow. While our captor was almost formless, the newcomer had a very definite shape. It resembled a cross between a bird and a lizard, its shape resembling a bird, as did tiny rudimentary wings and a long beak, while the scaly covering and the fact that it had four legs instead of two bore out the idea that it might be a lizard. Its huge birdlike beak was armed with three rows of long sharp teeth with which it was tearing at our captor. The purple amoeba was holding its a.s.sailant with a dozen of its thrown out feelers which were wrapped about the body and legs of the green horror. The whole battle was conducted in absolute silence.

"Now's our chance, Jim!" I cried. "Get away from here while that dragon has the amoeba busy!"

He jumped to the control levers of the flyer and pulled the starting switch well forward. The shock of the sudden start hurled me to the floor, but from where I fell I was able to watch the battle on the plain below us. It raged with uninterrupted fury and I felt certain of our escape when, with a shock which hurled both Jim and me to the ceiling, the flyer stopped. We fell back to the floor and I reflected that it was well for us that the interior of the flyer was so well padded. Had it not been, our bones would have been broken a dozen times by the shocks to which we had been subjected.

"What now?" I asked as I painfully struggled to my feet.

"Another of those purple amoebas," replied Jim from the vantage point of a window. "He's looking us over as if he were trying to decide whether we are edible or not."

I joined him at the window. The thing which had us was a replica of the monster we had left below us engaged in battle with the green dragon which had attacked it. The same indefinite and ever changing outline was evident, as well as the four huge eyes. The thing regarded us for a moment and slowly moved us up against its bulk until we touched it.
