"I"ll say it would. I"ll show you what heat means to them--showing you will be plainer than any amount of explanation," and he shot the visiray beam down toward the city of t.i.tania. Into a low-lying building it went, and Nadia saw a t.i.tanian foundry in full operation. Men clad in asbestos armor were charging, tending, and tapping great electric furnaces and crucibles; shrinking back and turning their armored heads away as the hissing, smoking melt crackled into the molds from their long-handled ladles. Nadia studied the foundry for a moment, interested, but unimpressed.
"Of course it"s hot there--foundries always _are_ hot," she argued.
"Yes, but you haven"t got the idea yet." Stevens turned again to the controls, following the sphere toward what was evidently a line of battle. "That stuff that they are melting and casting and that is so hot, is not metal, but _ice!_ Remember that the vital fluid of all life here, animal and vegetable, corresponding to our water, is probably more inflammable than gasoline. If they can"t work on ice-water without wearing suits of five-ply asbestos, what would a real heat-ray do to them? It"d be about like our taking a dive into the sun!"
"_Ice_!" she exclaimed. "Oh of course--but you couldn"t really believe a thing like that without seeing it, could you? Oh, Steve--how utterly horrible!"
The "Barkodar" had dropped down into a line of sister ships, and had gone into action in midair against a veritable swarm of foes. Winged centipedes they were--centipedes fully six feet long, hurling themselves along the ground and through the air in furious hordes. From the flying globes emanated pale beams of force, at the touch of which the Sedlor disappeared in puffs of vapor. Upon the ground huge tractors and trucks, manned by masked soldiery, mounted mighty reflectors projecting the same lethal beam. From globes and tanks there sounded a drumming roar and small capsules broke in thousands among the foe; emitting a red cloud of gas in which the centipedes shriveled and died. But for each one that was destroyed two came up from holes in the ground and the battle-line fell back toward t.i.tania, back toward a long line of derrick-like structures which were sinking force-rods into the ground in furious haste.
Stevens flashed on his ultra-violet projector and swung it into the thickest ranks of the enemy. In the beam many of the monsters died, but the Terrestrial ray was impotent compared with the weapons of the t.i.tanians, and Stevens, snapping off the beam with a bitter imprecation, shot the visiray out toward the bare, black cone of the extinct volcano and studied it with care.
"Barkovis, I"ve got a thought!" he snapped into the microphone. "Their stronghold is in that mountain, and there"s millions of them in there yet, coming out along their tunnels. They"ve got all the vegetation eaten away for miles, so there"s nothing much left there to spread a fire if I go to work on that hill, and, I"ll probably melt enough water to put out most of the fires I start. Detail me a couple of ships to drop your fire-foam bombs on any little blazes that may spread, and I"ll give them so much to worry about at home, that they"ll forget all about t.i.tania."
The _Forlorn Hope_ darted toward the crater, followed closely by two of the dazzling globes. They circled the mountain until Stevens found a favorable point of attack--a stupendous vertical cliff of mingled rock and crystal, upon the base of which he trained his terrific infra-red projector.
"I"m going to draw a lot of power," he warned the t.i.tanians then. "I"m giving this gun everything she"ll take."
He drove the ma.s.sive switches in, and as that dull red beam struck the cliff"s base there was made evident the awful effect of a concentrated beam of real and pure heat upon such an utterly frigid world. Vast columns of fire roared aloft, helping Stevens, melting and destroying the very ground as the bodies of the Sedlor in that gigantic ant-heap burst into flames. Clouds of superheated steam roared upward, condensing into a hot rain which descended in destructive torrents upon the fastnesses of the centipedes. As the raging beam ate deeper and deeper into the base of the cliff, the mountain itself began to disintegrate; block after gigantic block breaking off and crashing down into the flaming, boiling, seething cauldron which was the apex of that ravening beam.
Hour after hour Stevens drove his intolerable weapon into the great mountain, teeming with Sedlorean life; and hour after hour a group of t.i.tanian spheres stood by, deluging the surrounding plain with a flood of heavy fumes, through which the holocaust could not spread for lack of oxygen. Not until the mountain was gone--not until in its stead there lay a furiously boiling lake, its flaming surface hundreds of feet below the level of the plain--did Stevens open his power circuits and point the deformed prow of the _Forlorn Hope_ toward t.i.tania.
CHAPTER VII
The Return to Ganymede
"Must you you go back to Ganymede?" Barkovis asked, slowly and thoughtfully. He was sitting upon a crystal bench beside the fountain, talking with Stevens, who, dressed in his bulging s.p.a.ce-suit, stood near an airlock of the _Forlorn Hope_. "It seems a shame that you should face again those unknown, monstrous creatures who so inexcusably attacked us both without provocation."
"I"m not so keen on it myself, but I can"t see any other way out of it,"
the Terrestrial replied. "We left a lot of our equipment there, you know; and even if I should build duplicates here, it wouldn"t do us any good. These ten-nineteens are the most powerful transmitting tubes known when we left Tellus, but even their fields, dense as they are, can"t hold an ultra-beam together much farther than about six astronomical units. So you see we can"t possibly reach our friends from here with this tube; and your system of beam transmission won"t hold anything together even that far, and won"t work on any wave shorter than Roeser"s Rays. We may run into some more of those little spheres, though, and I don"t like the prospect. I wonder if we couldn"t plate a layer of that mirror of yours upon the _Hope_ and carry along a few of those bombs? By the way, what is that explosive--or is it something beyond Tellurian chemistry?"
"Its structure should be clear to you, although you probably could not prepare it upon Tellus because of your high temperature. It is nothing but nitrogen--twenty-six atoms of nitrogen combined to form one molecule of what you would call--N-twenty-six?"
"Wow!" Stevens whistled. "Crystalline, pentavalent nitrogen--no wonder it"s violent!"
"We could, of course, cover your vessel with the mirror, but I am afraid that it would prove of little value. The plates are so hot that it would soon volatilize."
"Not necessarily," argued Stevens. "We could live in number one life-boat, and shut off the heat everywhere else. The life-boats are insulated from the structure proper, and the inner and outer walls of the structure are insulated from each other. With only the headquarters lifeboat warm, the outer wall could be held pretty close to zero absolute."
"That is true. The bombs, of course, are controlled by radio, and therefore may be attached to the outer wall of your vessel. We shall be glad to do these small things for you."
The heaters of the _Forlorn Hope_ were shut off, and as soon as the outer sh.e.l.l had cooled to t.i.tanian temperature, a corps of mechanics set to work. A machine very like a concrete mixer was rolled up beside the steel vessel, and into its capacious maw were dumped boxes and barrels of dry ingredients and many cans of sparkling liquid. The resultant paste was pumped upon the steel plating in a sluggish, viscid stream, which spread out into a thick and uniform coating beneath the flying rollers of the skilled t.i.tanian workmen. As it hardened, the paste smoothed magically into the perfect mirror which covered the s.p.a.ce-vessels of the satellite; and a full dozen of the mirror explosive bombs of this strange people were hung in the racks already provided.
"Once again I must caution you concerning those torpedoes," Barkovis warned Stevens. "If you use them all, very well, but do not try to take even one of them into any region where it is very hot, for it will explode and demolish your vessel. If you do not use them, destroy them before you descend into the hot atmosphere of Ganymede. The mirror will volatilize harmlessly at the temperature of melting mercury, but the torpedoes must be destroyed. Once more, Tellurians, we thank you for what you have done, and wish you well."
"Thanks a lot for _your_ help--we still owe you something," replied Stevens. "If either of your power-plants go sour on you again, or if you need any more built, be sure to let us know--you can come close enough to the inner planets now on your own beam to talk to us on the ultra-communicator. We"ll be glad to help you any way we can--and we may call on you for help again. Goodbye, Barkovis--goodbye, all t.i.tania!"
He made his way through the bitterly cold shop into the control-room of their lifeboat, and while he was divesting himself of his heavy suit, Nadia lifted the _Forlorn Hope_ into the blue-green sky of t.i.tan, accompanied by an escort of the mirrored globes. Well clear of the atmosphere of the satellite, the terrestrial cruiser shot forward at normal acceleration, while the t.i.tanian vessels halted and wove a pattern of blue and golden rays in salute to the departing guests.
"Well, Nadia, we"re off--on a long trek, too."
"Said Wun Long Hop, the Chinese pee-lo," Nadia agreed. "Sure everything"s all x, big boy?"
"To nineteen decimals," he declared. "You couldn"t squeeze another frank into our acc.u.mulators with a proof-bar, and since they"re sending us all the power we want to draw, we won"t need to touch our batteries or tap our own beam until we"re almost to Jupiter. To cap the climax, what it takes to make big medicine on those spherical friends of ours, we"ve got. We"re not sitting on top of the world, ace--we"ve perched exactly at the apex of the entire universe!"
"How long is it going to take?"
"Don"t know. Haven"t figured it yet, but it"ll be _beaucoup_ days," and the two wanderers from far-distant Earth settled down to the routine of a long and uneventful journey.
They gave Saturn and his spectacular rings a wide berth and sped on, with ever-increasing velocity. Past the outer satellites, on and on, the good ship _Forlorn Hope_ flew into the black-and-brilliant depths of interplanetary s.p.a.ce. Saturn was an ever-diminishing disk beneath them: above them was Jupiter"s thin crescent, growing ever larger and more bright, and the Monarch of the Solar System, remaining almost stationary day after day, increasing steadily in apparent diameter and in brilliance.
Although the voyage from t.i.tan to Ganymede was long, it was not monotonous, for there was much work to be done in the designing and fabrication of the various units which were to comprise the ultra-radio transmitting station. In the various compartments of the _Forlorn Hope_ there were sundry small motors, blowers, coils, condensers, force-field generators, and other items which Stevens could use with little or no alteration; but for the most part he had to build everything himself.
Thus it was that time pa.s.sed quickly; so quickly that Jupiter loomed large and the Saturnian beam of power began to attenuate almost before the Terrestrials realized that their journey was drawing to an end.
"Our beam"s falling apart fast," Stevens read his meters carefully, then swung his communicator beam toward Jupiter. "We aren"t getting quite enough power to hold our acceleration at normal--think I"ll cut now, while we"re still drawing enough to let the t.i.tanians know we"re off their beam. We"ve got lots of power of our own now; and we"re getting pretty close to enemy territory, so they may locate that heavy beam.
Have you found Ganymede yet?"
"Yes, it will be on the other side of Jupiter by the time we get there.
Shall I detour, or put on a little more negative and wait for it to come around to this side?"
"Better wait, I think. The farther away we stay from Jupiter and the major satellites, the better."
"All x--it"s on. Suppose we"d better start standing watches, in case some of them show up?"
"No use," he dissented. "I"ve been afraid to put out our electro-magnetic detectors, as they could surely trace them in use.
Without them, we couldn"t spot an enemy ship even if we were looking right at it, except by accident; since they won"t be lighted up and it"s awfully hard to see anything out here, anyway. We probably won"t know they"re within a million kilometers until they put a beam on us.
Barkovis says that this mirror will reflect any beam they can use, and I"ve already got a set of photo-cells in circuit to ring an alarm at the first flash off of our mirror plating. I"d like to get in the first licks myself, but I haven"t been able to dope out any way of doing it.
So you might as well sleep in your own room, as usual, and I"ll camp here right under the panel until we get to Ganymede. There"s a couple of little things I just thought of, though, that may help some; and I"m going to do "em right now."
Putting on his s.p.a.ce-suit, he picked up a power drill and went out into the bitter cold of the outer structure. There he attacked the inner wall of their vessel, and the carefully established inter-wall vacuum disappeared in a screaming hiss of air as the tempered point bit through plate after plate.
"What"s the idea, Steve?" Nadia asked, when he had re-entered the control room. "Now you"ll have all that pumping to do over again."
"Protection for the mirrors," he explained. "You see, they aren"t perfect reflectors. There"s a little absorption, so that some stuff comes through. Not much, of course; but enough to kill some of those t.i.tanians and almost enough to ruin their ship got through in about ten minutes, and only one enemy was dealing it out. We can stand more than they could, of course, but the mirror itself won"t stand much more heat than it was absorbing then. But with air in those s.p.a.ces instead of vacuum, and with the whole ma.s.s of the _Hope_, except this one lifeboat, as cold as it is, I figure that there"ll be enough conduction and convection through them to keep the outer wall and the mirror cold--cool enough, at least, to hold the mirror on for an hour. If only one ship tackles us, it won"t be bad--but I figure that if there"s only one, we"re lucky."
Stevens" fears were only too well grounded, for during the "evening" of the following day, while he was carefully scanning the heavens for some sign of enemy craft, the alarm bell over his head burst into its brazen clamor. Instantly he shot out the detectors and ultra-lights and saw not one, but six of the deadly globes--almost upon them, at point-blank range! One was already playing a beam of force upon the _Forlorn Hope_, and the other five went into action immediately upon feeling the detector impulses and perceiving that the weapon of their sister ship had encountered an unusual resistance in the material of that peculiarly mirrored wedge. As those terrific forces struck her, the terrestrial cruiser became a vast pyrotechnic set piece, a dazzling fountain of coruscant brilliance: for the mirror held. The enemy beams shot back upon themselves and rebounded in all directions, in the same spectacular exhibition of frenzied incandescence which had marked the resistance of the t.i.tanian sphere to a similar attack.
But Stevens was not idle. In the instant of launching his detectors, as fast as he could work the trips, four of the frightful nitrogen bombs of t.i.tan--all that he could handle at once--shot out into s.p.a.ce, their rocket-tubes flaring viciously. The enemy detectors of course located the flying torpedoes immediately, but, contemptuous of material projectiles, the spheres made no attempt to dodge, but merely lashed out upon them with their ravening rays. So close was the range that they had no time to avoid the radio-directed bombs after discovering that their beams were useless against the unknown protective covering of those mirrored sh.e.l.ls. There were four practically simultaneous detonations--silent, but terrific explosions as the pent-up internal energy of solid pentavalent nitrogen was instantaneously released--and the four insensately murderous spheres disappeared into jagged fragments of wreckage, flying wildly away from the centers of explosion. One great ma.s.s of riven and twisted metal was blown directly upon the fifth globe, and Nadia stared in horrified fascination at the silent crash as the entire side of the ship crumpled inward like a sh.e.l.l of cardboard under the awful impact. That vessel was probably out of action, but Stevens was taking no chances. As soon as he had clamped a pale blue tractor rod upon the sixth and last of the enemy fleet, he drove a torpedo through the gaping wall and into the interior of the helpless war-vessel. There he exploded it, and the awful charge, detonated in that confined s.p.a.ce, literally tore the globular s.p.a.ce-ship to bits.
"We"ll show these jaspers what kind of trees make shingles!" he gritted between clenched teeth; and his eyes, hard now as gray iron, fairly emitted sparks as he launched four torpedoes upon the sole remaining globe of the squadron of the void. "I"ve had a lot of curiosity to know just what kind of unnatural monstrosities can possibly have such fiendish dispositions as they"ve got--but beasts, men or devils, they"ll find they"ve grabbed something this time they can"t let go of," and fierce blasts of energy ripped from the exhausts as he drove his missiles, at their highest possible acceleration, toward the captive sphere so savagely struggling at the extremity of his tractor beam.
