Invaders from the Infinite John W. Campbell (free ebook reader for iphone .txt) 📖

commented Arcot. He was watching intensely as a tiny ship swung away from one of the larger machines, and a tremendously powerful molecular started biting at the fort’s ray screen. The ship seemed nothing but a flying ray projector, which was what it was.

As they had hoped, the deadly new ray stabbed out from somewhere on the side of the fort. It was not within the fort.

“Which means,” pointed out Morey, “that they can’t make stuff to stand that. Probably the projector would be vulnerable.”

But a barrage of heat rays which immediately followed had no apparent effect. The little radio-controlled molecular beam projector lay on the rock under the melted ice, blazing incandescent with the rapidly released energy of the relux.

“Now to try the real test we came here for,” Morey clambered back to the power room, and turned on the controls of the magnetic beam. The ship was aligned, and then he threw the last switch. The great mass of the machine jerked violently, and plunged forward as the beam attracted the magnetic core of the Earth.

Morey could not see it, but almost instantly the shimmer of the molecular screen on the fort died out. The deadly ray sprang out from the Thessian projector⁠—and went dead. Frantically the Thessians tried weapon after weapon, and found them dead almost as soon as they were turned on⁠—which was the natural result in the terrific magnetic field.

And these men had iron bones, their very bones were attracted by the beam; they plunged upward toward the ship as the beam touched them, but, accustomed to the enormous gravitation accelerations of an enormous world, most of them were not killed.

“Ah⁠—!” exclaimed Arcot. He picked up the transmitter and spoke again to the Squadron Commander. “Squadron Commander Tharnton, what relux thickness does your ship carry?”

“Inch and a quarter,” replied the surprised voice of the commander.

“Any of the other ships carry heavier?”

“Yes, the special solar investigator carries five inches. What shall we do?”

“Tell him to lower his screen, and let loose at once on all operating forts. His relux will stand for the time needed to shut them down for their own screens, unless some genius decides to fight it out. As soon as the other ships can lower their screens, tell them to do so, and tell them to join in. I’ll be able to help then. My relux has been burned, and I’m afraid to lower the screen. It’s mighty thin already.”

The squadron commander was smiling joyously as he relayed the advice as a command.

Almost at once a single ship, blunt, an almost perfect cylinder, lowered its screen. In an instant the opalescence of the transformation showed on it, but its dozen ray projectors were at work. Fort after fort glowed opalescent, then flashed into protective ionization of screening. Quickly other ships lowered their screens, and joined in. In a moment more, the forts had been forced to raise their screens for protection.

A disc of artificial matter ten feet across suddenly appeared beside the Ancient Mariner. It advanced with terrific speed, struck the great dome of the fort, and the dome caved, bent in, bent still more⁠—but would not puncture. The disc retreated, became a sharp cone, and drove in again. This time the point smashed through the relux, and made a small hole. The cone seemed to change gradually, melting into a cylinder of twenty foot diameter, and the hole simply expanded. It continued to expand as the cylinder became a huge disc, a hundred feet across, set in the wall.

Suddenly it simply dissolved. There was a terrific roar, and a mighty column of white rushed out of the gaping hole. Figures of Thessians caught by the terrific current came rocketing out. The inside was at last visible. The terrific pressure was hurling the outside line of ships about like thistledown. The Ancient Mariner reeled back under the tremendous blast of expanding gas. The snow that fell to the boiling water below was not water, in toto; some was carbon dioxide⁠—and some oxygen chilled in the expansion of the gas. It was snowing within the dome. The falling forms of Thessians were robbed of the life-giving air pressure to which they were accustomed. But all this was visible for but an instant.

Then a small, thin sheet of artificial matter formed beside the fort, and advanced on the dome. Like a knife cutting open an orange, it simply went around the dome’s edge, the great dome lifted like the lid of a teapot under the enormous gas pressure remaining⁠—then dropped under its own weight.

The artificial matter was again a huge disc. It settled over the exact center of the dome⁠—and went down. The dome caved in. It was crushed under a load utterly inestimable. Then the great disc, like some monstrous tamper, tamped the entire works of the Thessians into the bedrock of the island. Every ship, every miniature fort, every man was caught under it⁠—and annihilated.

The disc dissolved. A terrific barrage of heat beams played over the island, and the rock melted, flowed over the ruins, and left only the spumes of steam from the Arctic ice rising from a red-hot: mass of rock, contained a boiling pool.

The Battle of the Arctic was done.

XI “Write Off the Magnet”

“Squadron commander Tharnton speaking: Squadron 73-B of Planetary Guard will follow orders from Dr. Arcot directly. Heading south to Antarctica at maximum speed,” droned the communicator. Under the official tone of command was a note of suppressed rage and determination. “And the squadron commander wishes Dr. Arcot every success in wiping out Antarctica as thoroughly and completely as he destroyed the Arctic base.”

The flight of ships headed south at a speed that heated them white in the air, thin as it was at the hundred mile altitude, yet going higher would have taken unnecessary time, and the white heat meant no discomfort. They reached Antarctica in about ten minutes. The Thessian ships were just entering through great locks in the
