Part 10 (2/2)

They can do it almost instantly from a distance. The other Guards at once let loose with all their moleculars and cosmics. The enemy shunted off the moleculars, and wiped out the Guard almost instantly.

”Of course, I could explain the screen, but not the detonation ray. I am inclined to believe from other casualties that the destruction, though reported as an instantaneous explosion, was not that. Other s.h.i.+ps have been destroyed, and they seemed to catch fire, and burn, but with terrific speed, more like gun powder than coal. It seems to start a spreading decomposition, the s.h.i.+p lasts perhaps ten minutes. If it went instantly, the shock of such a tremendous energy release would disrupt the planet.

”At any rate, the great fleet separated, twelve went to the North Pole of Earth, twelve to the south, and similarly twelve to each pole of Venus. Then one of them turned, and went back to wherever it had come from, to report. Just turned and vanished. Similarly one from Venus turned and vanished. That leaves twelve at each of the four poles, for, as I said, there were an even fifty.

”They all followed the same tactics on landing, so I'll simply tell what happened in Attica. In the North they had to pick one of the islands a bit to the south of the pole. They melted about a hundred square miles of ice to find one.

”The s.h.i.+ps arranged themselves in a circle around the place, and literally hundreds of men poured out of each and fell to work. In a short time, they had set up a number of machines, the parts coming from the s.h.i.+ps. These machines at once set to work, and they built up a relux wall. That wall was at least six feet thick; the floor was lined with thick relux as well as the roof, which is simply a continuation of the wall in a perfect dome. They had so many machines working on it, that within twenty-four hours they had it finished.

”We attacked twice, once in practically our entire force, with some ray-s.h.i.+eld machines. The result was disastrous. The second attack was made with ray s.h.i.+elded machines only, and little damage was done to either side, though the enemy were somewhat impeded by ma.s.ses of ice hurled into their position. Their relux disintegration ray was conspicuous by its absence.

”Yesterday--and it seems a lot longer than that, son--they started it again. They'd been unloading it from the s.h.i.+p evidently. We had had ray-s.h.i.+elded machines out, but they simply melted. They went down, and Earth retreated. They're in their fortress now. We don't know how to fight them. Now, for G.o.d's sake, tell us you have learned of some weapon, son!”

The older man's face was lined. His iron gray head showed his fatigue due to hours of concentration on his work.

”Some,” replied Arcot briefly. He glanced around. Other men had arrived, men whom he met in his work. But there were Venerians here, too, in their protective suits, insulated against the cold of Earth, and against its atmosphere.

”First, though, gentlemen, allow me to introduce Stel Felso Theu of the planet Talso, one of our allies in this struggle, and Zezdon Afthen and Fentes of Ortol, one of our other allies.

”As to progress, I can say only that it is in a more or less rudimentary stage. We have the basis for great progress, a weapon of inestimable value--but it is only the basis. It must be worked out. I am leaving with you today the completed calculations and equations of the time field, the system used by the Thessian invaders in propelling their s.h.i.+ps at a speed greater than that of light. Also, the uncompleted calculations in regard to another matter, a weapon which our ally, Talso, has given us, in exchange for the aid we gave in allowing them the use of one of our generators. Unfortunately the s.h.i.+p could not spare more than the single generator. I strongly advise rus.h.i.+ng a number of generators to Talso in intergalactic freighters. They badly need power--power of respectable dimensions.

”I have stopped on Earth only temporarily, and I want to leave as soon as possible. I intend, however, to attempt an attack on the Arctic base of the Thessians, in strong hopes that they have not armored against one weapon that the _Ancient Mariner_ carries--though I sadly fear that old Earth herself has played us false here. I hope to use the magnetic beam, but Earth's polar magnetism may have forced them to armor, and they may have sufficiently heavy material to block the effects.”

Morey already had a ground crew servicing the s.h.i.+p. He gave designs to machinists on hand to make special control panels for the large artificial matter machines. Arcot and Wade got some badly needed equipment.

In six hours, Arcot had announced himself ready, and a squadron of Planetary Guard s.h.i.+ps were ready to accompany the refitted _Ancient Mariner_.

They approached the pole cautiously, and were rewarded by the hiss and roar of ice melting into water which burst into steam under a ray. It was coming from an outpost of the camp, a tiny dome under a great ma.s.s of ice. But the dome was of relux. A molecular reached down from a Guard s.h.i.+p--and the Guard s.h.i.+p crumbled suddenly as dozens of moleculars from the points. .h.i.t it.

”They know how to fight this kind of a war. That's their biggest advantage,” muttered Arcot. Wade merely swore.

”Ray screens, no moleculars!” snapped Arcot into the transmitter. He was not their leader, but they saw his wisdom, and the squadron commander repeated the advice as an order. In the meantime, another s.h.i.+p had fallen. The dome had its screen up, allowing the mult.i.tudes of hidden stations outside to fight for it.

”Hmm--something to remember when terrestrians have to retire to forts.

They will, too, before this war is over. That way the main fort doesn't have to lower its ray screen to fight,” commented Arcot. He was watching intensely as a tiny s.h.i.+p swung away from one of the larger machines, and a tremendously powerful molecular started biting at the fort's ray screen. The s.h.i.+p 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 s.h.i.+p was aligned, and then he threw the last switch. The great ma.s.s 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 s.h.i.+mmer 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 s.h.i.+p 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 s.h.i.+p carry?”

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