The Skylark of Space

The pulsating air and the chattering sounders were giving the same dire warning, the alarm extraordinary of invasion, of imminent and catastrophic danger from the air. "Don't try to reach the palace. Everyone on the ground will have time enough to hide in the deep, arenak-protected pits beneath the buildings, and you would be killed by the invaders long before you could reach the palace. If we can repel the enemy and keep them from landing, the women will be perfectly safe, even though the whole city is destroyed. If they effect a landing we are lost." "They'll not land, then," Seaton answered grimly, as he sprang into the Skylark and took his place at the board. As Crane took out his wireless, Seaton cautioned him. "Send in English, and tell the girls not to answer, as these devils can locate the calls within a foot and will be able to attack the right spot. Just tell them we're safe in the Skylark. Tell them to sit tight while we wipe out this gang that is coming, and that we'll call them, once in a while, when we have time, during the battle." Before Crane had finished sending the message the crescendo whine of enormous propellers was heard. Simultaneously there was a deafening concussion and one entire wing of the palace disappeared in a cloud of dust, in the midst of which could be discerned a few flying fragments. The air was filled with Mardonalian warships. They were huge vessels, each mounting hundreds of guns, and the rain of high-explosive shells was rapidly reducing the great city to a wide-spread heap of debris. Seaton's hand was upon the lever which would hurl the Skylark upward into the fray. Crane and DuQuesne, each hard of eye and grim of jaw, were stationed at their machine-guns. "Something's up!" exclaimed Seaton. "Look at the Kondal!" Something had happened indeed. Dunark sat at the board, his hand upon the power lever, and each of his crew was in place, grasping his weapon, but every man was writhing in agony, unable to control his movements. As they stared, momentarily spellbound, the entire crew ceased their agonized struggles and hung, apparently lifeless, from their supports. "They've got to 'em some way--let's go!" yelled Seaton. As his hand tightened upon the lever, a succession of shells burst upon the dock, wrecking it completely, all three men fancied that the world had come to an end as the stream of high explosive was directed against their vessel. But the four-foot shell of arenak was impregnable, and Seaton shot the Skylark upward into the midst of the enemy fleet. The two gunners fired as fast as they could sight their weapons, and with each shot one of the great warships was blown into fragments. The Mardonalians then concentrated the fire of their entire fleet upon their tiny opponent. From every point of the compass, from above and below, the enemy gunners directed streams of shells against the dodging vessel. The noise was more than deafening, it was one continuous, shattering explosion, and the Earth-men were surrounded by such a blaze of fire from the exploding shells that they could not see the enemy vessels. Seaton sought to dodge the shells by a long dive toward one side, only to find that dozens of new opponents had been launched against them--the deadly airplane-torpedoes of Osnome. Steered by wireless and carrying no crews, they were simply winged bombs carrying thousands of pounds of terrific electrical explosive--enough to kill the men inside the vessel by the concussion of the explosion, even should the arenak armor be strong enough to withstand the blow. Though much faster than the Osnomian vessels, they were slow beside the Skylark, and Seaton could have dodged a few of them with ease. As he dodged, however, they followed relentlessly, and in spite of those which were blown up by the gunners, their number constantly increased until Seaton thought of the repellers. "'Nobody Holme' is right!" he exclaimed, as he threw on the power actuating the copper bands which encircled the hull in all directions. Instantly the torpedoes were hurled backward, exploding as the force struck them, and even the shells were ineffective, exploding harmlessly, as they encountered the zone of force. The noise of the awful detonations lessened markedly. "Why the silence, I wonder?" asked Seaton, while the futile shells of the enemy continued to waste their force some hundreds of feet distant from their goal, and while Crane and DuQuesne were methodically destroying the huge vessels as fast as they could aim and fire. At every report one of the monster warships disappeared--its shattered fragments and the bodies of its crew hurtling to the ground. His voice could not be heard in even the lessened tumult, but he continued: "It must be that our repellers have set up a partial vacuum by repelling even the air!" * * * * * Suddenly the shelling ceased and the Skylark was enveloped by a blinding glare from hundreds of great reflectors; an intense, searching, bluish-violet light that burned the flesh and seared through eyelids and eyeballs into the very brain. "Ultra-violet!" yelled Seaton at the first glimpse of the light, as he threw on the power. "Shut your eyes! Turn your heads down!" Out in space, far beyond reach of the deadly rays, the men held a short conference, then donned heavy leather-and-canvas suits, which they smeared liberally with thick red paint, and replaced the plain glasses of their helmets with heavy lenses of deep ruby glass. "This'll stop any ultra-violet ray ever produced," exulted Seaton, as he again threw the vessel into the Mardonalian fleet. A score of the great vessels met their fate before the Skylark was located, and, although the terrible rays were again focused upon the intruder in all their intensity, the carnage continued. In a few minutes, however, the men heard, or rather felt, a low, intense vibration, like a silent wave of sound--a vibration which smote upon the eardrums as no possible sound could smite, a vibration which racked the joints and tortured the nerves as though the whole body were disintegrating. So sudden and terrible was the effect that Seaton uttered an involuntary yelp of surprise and pain as he once more fled into the safety of space. "What the devil was that?" demanded DuQuesne. "Was it infra-sound? I didn't suppose such waves could be produced." "Infra-sound is right. They produce most anything here," replied Seaton, and Crane added: "Well, about three fur suits apiece, with cotton in our ears, ought to kill any wave propagated through air." The fur suits were donned forthwith, Seaton whispering in Crane's ear: "I've found out something else, too. The repellers repel even the air. I'm going to shoot enough juice through them to set up a perfect vacuum outside. That'll kill those air-waves." Scarcely were they back within range of the fleet when DuQuesne, reaching for his gun to fire the first shot, leaped backward with a yell. "Beat it!" Once more at a safe distance, DuQuesne explained. "It's lucky I'm so used to handling hot stuff that from force of habit I never make close contact with anything at the first touch. That gun carried thousands of volts, with lots of amperage behind them, and if I had had a good hold on it I couldn't have let go. We'll block that game quick enough, though. Thick, dry gloves covered with rubber are all that is necessary. It's a good thing for all of us that you have those fancy condensite handles on your levers, Seaton." "That was how they got Dunark, undoubtedly," said Crane, as he sent a brief message to the girls, assuring them that all was well, as he had been doing at every respite. "But why were we not overcome at the same time?" "They must have had the current tuned to iridium, and had to experiment until they found the right wave for steel," Seaton explained. "I should think our bar would have exploded, with all that current. They must have hit the copper range, too?" Seaton frowned in thought before he answered. "Maybe because it's induced current, and not a steady battery impulse. Anyway, it didn't. Let's go!" "Just a minute," put in Crane. "What are they going to do next, Dick?" "Search me. I'm not used to my new Osnomian mind yet. I recognize things all right after they happen, but I can't seem to figure ahead--it's like a dimly-remembered something that flashes up as soon as mentioned. I get too many and too new ideas at once. I know, though, that the Osnomians have defenses against all these things except this last stunt of the charged guns. That must be the new one that Mardonale stole from Kondal. The defenses are, however, purely Osnomian in character and material. As we haven't got the stuff to set them up as the Osnomians do, we'll have to do it our own way. We may be able to dope out the next one, though. Let's see, what have they given us so far?" "We've got to hand it to them," responded DuQuesne, admiringly. "They're giving us the whole range of wave-lengths, one at a time. They've given us light, both ultra-violet and visible, sound, infra-sound, and electricity--I don't know what's left unless they give us a new kind of X-rays, or Hertzian, or infra-red heat waves, or...." "That's it, heat!" exclaimed Seaton. "They produce heat by means of powerful wave-generators and by setting up heavy induced currents in the armor. They can melt arenak that way." "Do you suppose we can handle the heat with our refrigerators?" asked Crane. "Probably. We have a lot of power, and the new arenak cylinders of our compressors will stand anything. The only trouble will be in cooling the condensers. We'll run as long as we have any water in our tanks, then go dive into the ocean to cool off. We'll try it a whirl, anyway." * * * * * Soon the Skylark was again dealing out death and destruction in the thick of the enemy vessels, who again turned from the devastation of the helpless city to destroy this troublesome antagonist. But in spite of the utmost efforts of light-waves, sound-waves, and high-tension electricity, the space-car continued to take its terrible toll. As Seaton had foretold, the armor of the Skylark began to grow hot, and he turned on the full power of the refrigerating system. In spite of the cooling apparatus, however, the outer walls finally began to glow redly, and, although the interior was comfortably cool, the ends of the rifle-barrels, which were set flush with the surface of the revolving arenak globes which held them, softened, rendering the guns useless. The copper repellers melted and dripped off in flaming balls of molten metal, so that shells once more began to crash against the armor. DuQuesne, with no thought of quitting apparent in voice or manner, said calmly: "Well, it looks as though they had us stopped for a few minutes. Let's go back into space and dope out something else." Seaton, thinking intensely, saw a vast fleet of enemy reinforcements approaching, and at the same time received a wireless call directed to Dunark. It was from the grand fleet of Kondal, hastening from the bordering ocean to the defense of the city. Using Dunark's private code, Seaton told the Karbix, who was in charge of the fleet, that the enemy had a new invention which would wipe them out utterly without a chance to fight, and that he and his vessel were in control of the situation; and ordered him to see that no Kondalian ship came within battle range of a Mardonalian. He then turned to Crane and DuQuesne, his face grim and his fighting jaw set. "I've got it doped right now. Give the Lark speed enough and she's some bullet herself. We've got four feet of arenak,
