Astounding Stories of Super-Science January 1931 Part 46

It was the earth-shaking thunder of the big gun that hastened their final preparations and made McGuire tremble with suppressed excitement where he helped Sykes to draw off a syrupy liquid into heavy crystal flasks.

There were many of these, and the two men would allow no others to touch them, but stored them themselves and nested each one in a soft bed within the submarine. Then one last repet.i.tion of their half-formed plans to Djorn and his followers and a rush toward the wharf where the submarine was waiting.

Althora was waiting, too, and McGuire wasted minutes in a pet.i.tion that he knew was futile.

"Wait here, Althora," he begged. "I will come back; this is no venture for you to undertake. I can take my chances with them, but you--! It is no place for you," he concluded lamely.

"There is no other place for me," she said; "only where you are." And she led the way while the others followed into the lighted control room of the big under-water craft.

McGuire's eyes were misty with a blurring of tears that were partly from excitement, but more from a feeling of helpless remonstrance that was mingled with pure pride. And his lips were set in a straight line.

The magnetic pull that held them to their anchorage was reversed; the ship beneath them was slipping smoothly beneath the surface and out to sea, guided through its tortuous windings of water-worn caves and rocky chambers under the sea by the invisible electric cords that drew it where they would.

And ahead on some mysterious island was a gun, a thing of size and power beyond anything of Earth. He was going to spike that gun if it was the last act of his life; and Althora was going with him. He drew her slim body to him, while his eyes stared blindly, hopefully, toward what the future held.

CHAPTER XVI

Throughout the night they drove hour after hour at terrific speed. The ship was running submerged, for McGuire was taking no slightest chance of their being observed from the air. He and the others slept at times, for the crew that handled the craft very evidently knew the exact course, and there were mechanical devices that insured their safety. A ray was projected continuously ahead of them; it would reflect back and give on an indicator instant warning of any derelict or obstruction. Another row of quivering needles gave by the same method the soundings from far ahead.

But the uncertainty of what their tomorrow might hold and the worry and dread lest he find himself unable to damage the big gun made real rest impossible for McGuire.

But he was happy and buoyant with hope when, at last, the green light from the ports showed that the sun was shining up above, and the slackening drive of the submarine's powerful motors told that their objective was in sight.

They lay quietly at last while a periscope of super-sensitiveness was thrust cautiously above the water. It brought in a panoramic view of the sh.o.r.eline ahead, amplified it and projected the picture in clear-cut detail upon a screen. If Lieutenant McGuire had stood on the wet deck above and looked directly at the island the sight could have been no clearer. The colors of torn and blasted tree-growths showed in all their pale shades, and there was stereoscopic depth to the picture that gave no misleading illusions as to distance.

The sh.o.r.e was there with the white spray of breakers on a rocky shoal, and a beach beyond. And beyond that, in hard outline against a golden sky, was a gigantic tube that stood vertically in air to reach beyond the upper limits of the periscope's vision.

McGuire tingled at the sight. To be within reach of this weapon that had sent those blasting, devastating missiles upon the earth! He paced back and forth in the small room to stop and stare again, and resume his pacing that helped to while away the hours they must wait. For there were man-shapes swarming over the land, and the dull, blood-red of their loose uniforms marked them as members of the fighting force sp.a.w.ned by this prolific breed.

"Not a chance until they're out of the picture," said the impatient man; "they would snow us under. It's just as I thought: we must wait until the gun is ready to fire; then they will beat it. They won't want to be around when that big boy cuts loose."

"And then?" asked Althora.

"Then Sykes and I will take our collection of gallon flasks ash.o.r.e, and I sure hope we don't stumble." He grinned cheerfully at the girl.

"That reinforced concrete dome seems to be where they get down into the ground; it is close to the base of the gun. We will go there--blow it open if we have to--but manage in some way to get down below. Then a time-fuse on the charge, and the boat will take me off, and we will leave as fast as these motors can drive us."

He omitted to mention any possible danger to Sykes and himself in the handling of their own explosive, and he added casually, "You will stay here and see that there is no slip-up on the getaway."

He had to translate the last remark into language the girl could understand. But Althora shook her head.

"You do try so hard to get rid of me, Tommy," the laughed, "but it is no use. I am going with you--do not argue--and I will help you with the attack. Three will work faster than two--and I am going."

McGuire was silent, then nodded his a.s.sent. He was learning, this Earth-man, what individual freedom really meant.

Only the western sky showed golden ma.s.ses on the shining screen when McGuire spoke softly to the captain:

"Your men will put us ash.o.r.e; you may ask them to stand by now." And to Professor Sykes, "Better get that 'soup' of yours ready to load."

The red-clad figures were growing dim on the screen, and the blotches of colors that showed where they were grouped were few. Some there were who left such groups to flee precipitately toward a waiting airship.

This was something the lieutenant had not foreseen. He had expected that the force that served the gun would have some shock-proof shelter; he had not antic.i.p.ated a fighting ship to take them away.

"That's good," he exulted; "that is a lucky break. If they just get out of sight we will have the place to ourselves."

There were no red patches on the screen now, and the picture thrown before them showed the big ship, its markings of red and white distinct even in the shadow-light of late afternoon, rising slowly into the air. It gathered speed marvelously and vanished to a speck beyond the land.

"We're getting the breaks," said McGuire crisply. "All right--let's go!"

The submarine rose smoothly, and the sealed doors in the superstructure were opened while yet there was water to come trickling in. Men came with a roll of cloth that spread open to the shape of a small boat, while a metal frame expanded within it to hold it taut.

McGuire gasped with dismay as a seaman launched it and leaped heavily into the frail sh.e.l.l to attach a motor to one end.

"Metal!" the captain rea.s.sured him; "woven metal, and water-tight! You could not pierce it with anything less than a projector."

Sykes was ready with one of the crystal flasks as the boat was brought alongside, and McGuire followed with another. They took ten of the harmless-looking containers, and both men held their breaths as the boat grounded roughly on the boulder-strewn sh.o.r.e.

They lifted them out and bedded them in the sand, then returned to the submarine. This time Althora, too, stepped into the boat. They loaded in the balance of the containers; the motor purred. Another landing, and they stood at last on the island, where a mammoth tube towered into the sky and the means for its destruction was at their feet.

But there was little time; already the light was dimming, and the time for the firing of the big weapon was drawing near. The men worked like mad to carry the flasks to the base of the gun, where a dome of concrete marked the entrance to the rooms below.

Each man held a flask of the deadly fluid when Althora led the way where stairs went deep down into the earth under the domed roof. This part of the work had been foreseen, and the girl held a slender cylinder that threw a beam of light, intensely bright.

They found a surprising simplicity in the arrangements underground.

Two rooms only had been carved from the solid rock, and one of these ended in a wall of gray metal that could be only the great base of the gun. But nowhere was a complication of mechanism that might be damaged or destroyed, nor any wiring or firing device.

A round door showed sharp edges in the gray metal, but only the strength of many men could have removed its huge bolts, and these two knew there must be other doors to seal in the mighty charge.

"Not a wire!" the scientist exclaimed. "How do they fire it?" The answer came to him with the question.

"Radio, of course; and the receiving set is in the charge itself; the barrel of the gun is its own antenna. They must fire it from a distance--back on the island where we were, perhaps. It would need to be accurately timed."

"Come on!" shouted McGuire, and raised the flask of explosive to his shoulder.

Each one knew the need for haste; each waited every moment for the terrible blast of gun-fire that would jar their bodies to a lifeless pulp or, by detonating their own explosive, destroy them utterly. But they carried the flasks again to the top, and the three of them worked breathlessly to place their whole supply where McGuire directed.

The ma.s.sive barrel of the gun was beside them; it was held in tremendous castings of metal that bolted to anchorage in the ground.

One great brace had an overhanging f.l.a.n.g.e; the explosive was placed beneath it.
