There pa.s.sed hours of weary, tortured stumblings, and slitherings, and sudden falls--down, always down, interminably. A pale glimmering showed us the way, a dim shining through the icy walls.
At last, faint with toil, bleeding and torn from gla.s.s-sharp splinters, we reached a level chamber, vaulted, surprisingly, with solid rock. It was good to see something of the earth again, something that was not that deadly, all-embracing ice. At the far end lay a blinding patch. I blinked.
"Sunlight!" I shouted joyously.
"Yes," Keston answered quietly. "That opening leads directly into the valley on our land."
Abud roused himself from the unreasoning dread he had been in. It was the first time he had spoken.
"Let us get out of here. I feel as though I"m in a tomb."
"Are you mad?" Keston said sharply. "The visors would pick you up at once. You wouldn"t last very long."
Abud stopped suddenly. There was a plaintive, helpless note to him.
"But we can"t stay here forever. We"d starve, or die of cold. Isn"t there some way to get back to the top of the Glacier?"
"No--only the way we came. And that"s been blocked with terminite."
"Then what are we going to do? You"ve led us into a slow death, you with your boasted brains!"
"That remains to be seen," was the calm retort. "In the meantime, we"re hungry. Let us eat."
And the amazing man drew out of his torn flapping furs the gobs of meat he had cut from the dead bear. I had quite forgotten them. With a glad cry, I too reached into my garments and brought out my supply.
Abud"s eyes glinted evilly. His hand stole stealthily to the bone knife in its skin sheath. His spear had been dropped long before.
"None of that," Keston said sharply. "We"ll all share equally, even though you have no food. But if you try to hog it all, or use force, you"ll die as well as we. There"s only enough for a meal or two; and then what will you do?"
Abud saw that. He needed Keston"s brains. His eyes dropped, and he mumbled something about our misunderstanding his gesture. We let it go at that. We had to. He could have killed us both if he wished.
So we divided our food with painstaking fairness. How we gorged on the raw red flesh and thick greasy fat! Food that would have disgusted us when we lived and worked in the Central Station, now was ambrosia to our sharpened appet.i.tes. When not the least sc.r.a.p was left, and we had slaked our thirst with chunks of ice from the cavern floor, I spoke.
"What is that plan you spoke of, Keston, for reconquering the earth from the machines?"
Abud looked up abruptly at my question, and it seemed to me that a crafty smile glinted in the small pig eyes.
Keston hesitated a moment before he spoke.
"I confess my plans have been materially impeded by this sudden predicament we find ourselves in, thanks to our good friend here." He ironically indicated Abud.
The big prolat merely grunted.
"However," Keston continued, "I"ll have to make the best of circ.u.mstances, without the aid of certain materials that I had expected to a.s.semble.
"The idea is a simple one. You"ve noted no doubt how the terminus of the Glacier opposite the Central Control Station overhangs. The brow, over a thousand feet up, extends out at least a hundred feet beyond the base."
I nodded a.s.sent, though Abud seemed startled. Many times had Keston and I speculated on the danger of an avalanche at this point, and wondered why the Station had been built in such an exposed place. Once indeed we had ventured to suggest to the aristo Council the advisability of removing the Central Control to some other point, but the cold silence that greeted our diffident advice deterred us from further pursuit of the subject.
"Now, you know as well as I," Keston resumed, "that a glacier is merely a huge river of ice, and, though solid, partakes of some of the qualities of freely flowing water. As a matter of fact, glaciers do flow, because the tremendous pressure at the bottom lowers the melting point of ice to such a degree that the ice actually liquefies, and flows along."
I followed him eagerly in these elementary statements, trying to glimpse what he was driving at, but Abud"s brute features were fixed in a blank stare.
"This glacier does move. We"ve measured it--a matter of an inch or two a day. If, however,"--Keston"s voice took on a deeper note--"we can manage to hasten that process, the Glacier will overwhelm the countryside."
He paused, and that gave me a chance to interpose some objections.
"But hold on a moment. In the first place it is an absolute impossibility with the means at our command, or even with every appliance, to melt the face of the whole Northern Glacier. In the second place, even if we could, the whole world would be overwhelmed, and then where would we be?"
Keston looked at me a trifle scornfully. "Who said we were going to melt the entire glacier? Remember I spoke only of the place of the overhang. Set that in motion, and we don"t have to worry about the problem any further."
"Why not?" I inquired incredulously. "Suppose you _do_ wipe out all the machines in this particular vicinity, won"t there be tremendous numbers left all through the Equatorial Belt?"
"Of course," he explained patiently, "and what if they are? What are all these machines but inanimate mechanisms, things of metal and rubber and quartz. What makes them the monsters they have become?"
I smote my forehead in anger. "What a fool! Now I see it. It"s the master machine you"re after."
"Exactly," he smilingly agreed. "Overwhelm, destroy this devilish creature of mine, with its unhuman intelligence, and the machines are what they were before: merely obedient slaves."
I pondered that a moment. "And how, may I ask, are you going to force this old Glacier to move."
His face clouded. "That"s the trouble. Up on the ice I was working on that problem, and had managed secretly to rig up a contrivance that would have done the trick. But we can"t go back for it. That way is blocked." He mused, half to himself. "If only we could lay our hands on a solar disintegrating machine, the difficulty would be solved."
At the name, Abud"s face, that had been a study in blank incomprehension, lit up.
"Solar disintegrating machine?" he inquired. "Why there"s one stationed not more than a few hundred yards away from here. This area, 2-RX, was my sector, you know."
"Of course, of course," shouted Keston, "I"d quite forgotten. The very thing. You"re not half bad, Abud, if you"d only stop trying to rely on brute strength instead of brains," he concluded.
Abud said nothing, but I noticed a quick flash of hatred that pa.s.sed in an instant, leaving a blank countenance. I thought to myself, "You"ll bear watching, my fine fellow. I don"t trust you at all."
Keston was speaking. "We"ll have to wait until nightfall. The master machine won"t expect us down at the base, so I"m positive the search-rays won"t be focussed along the ground. We"ll sneak to the machine, smash its visor and radio units, so it won"t give the alarm, and haul it back. Then I"ll show you what"s next to be done."
Night came at last, leaden footed, though we were burning with impatience. Very softly we crawled out of the cave, three shadows.
Fortunately there was no moon. The great Glacier loomed ominously above us, dimly white. High overhead hovered the green signal lights of the machine planes, their search rays focussed in blinding glares on the rim of the upper ice.
It did not take us long to find the dark bulk of the disintegrator. It was a squat cylinder, for all the world like a huge boiler. At one end there up-ended a periscope arrangement which broadened out to a funnel. In the funnel was a very powerful lens, cut to special measurements. The light of the sun, or any light, for that matter, was concentrated through the lens onto a series of photo-electric cells, composed of an alloy of selenium and the far more delicate element, illinium. A high tension current was there created, of such powerful intensity that it disintegrated the atoms of every element except osmium and indium into their const.i.tuent electrons. Consequently the interior as well as the long slit nozzle orifice at the other end, were made of these resistant metals.
Through a special process the tremendously powerful current was forced through the wide-angled nozzle in a spreading thin plate ray that sheared through earth and rock and metals as if they were b.u.t.ter.
