"I've already had the Velantians build us some baffles—we've got lots of spare tantalum, tungsten, carballoy, and refractory, you know—just in case we should want to use them."
"Radiation…detection…decrement…cosine squared theta…um…call it point zero zero three eight," the engineer mumbled, squinting at his "slip– stick." "Times half a million…about nineteen hundred lights will have to be tops. Mighty slow, but we would get there sometime—maybe. Now about the baffles," and he went into another bout of computation during which could be distinguished a few such words as "temperature…inert corpuscles… velocity…fusion–point…Weinberger's Constant…" Then.
"It figures that at about eighteen hundred lights your baffles go out," he announced. "Pretty close check with the radiation limit. QX, I guess—but I shudder to think of what we may have to do to that Bergenholm to hold it together that long."
"It's not so hot. I don't think much of the scheme myself," admitted Kinnison frankly. "Probably you can think up something better before…"
"Who, me? What with?" Thorndyke interrupted, with a laugh. "Looks to me like our best bet—anyway, ain't you the master mind of this outfit? Blast off!"
Thus it came about that long later, the Lensman cut off his interference, cut off his driving power, cut off every mechanism whose operation generated vibrations which would reveal to enemy detectors the location of his cruiser. Space–suited mechanics emerged from the stern lock and fitted over the still white–hot vents of the driving projectors the baffles they had previously built.
It is of course well known that all. ships of space are propelled by the. inert projection, by means of high–potential static fields, of nascent fourth– order particles or "corpuscles," which are formed, inert, inside the inertialess projector, by the conversion of some form of energy into matter. This conversion liberates some heat, and a vast amount of light. This light, or "flare," shining as it does directly upon and through the highly tenuous gas formed by the, projected corpuscles, makes of a speeding spaceship one of the most gorgeous spectacles known to man, and it was this very spectacular effect that Kinnison and his crew must do away with if their bold scheme were to have any chance at all of success.
The baffles were in place. Now, instead of shooting out in tell–tale luminescence, the light was shut in—but so, alas, was approximately three percent of the heat. And the generation of heat must be cut down to a point at which the radiation–equilibrium temperature of the baffles would be below the point of fusion of the refractories of which they were composed. This would cut down their speed tremendously, but on the other hand, they were practically safe from detection and would reach Trenco eventually—if the Bergenholm held out.
Of course there was still the chance of visual or electromagnetic detection, but that chance was vanishingly small. The proverbial task of finding a needle in a haystack would be an easy one indeed, compared to that of seeing in a telescope or upon visiplate or magneplate a dead–black, lightless bip in the infinity of space. No, the Bergenholm was their great, their only concern, and the engineers lavished upon that monstrous fabrication of metal a devotion to which could be likened only that of a corps of nurses attending the ailing baby of a multi–millionaire.
This concentration of attention did get results. The engineers still found it necessary to sweat and to grunt and to swear, but they did somehow keep the thing running—most of the time. Nor were they detected—then.
For the attention of the pirate high command was very much taken up with that fast–moving, that ever–expanding, that peculiarly–fluctuating volume of interference, utterly enigmatic as it was and impenetrable to their every instrument of communication. In that system was the Prime Base of the Galactic Patrol. Therefore it was the Lensman's work—undoubtedly the same Lensman who had conquered one of their super–ships and, after having learned its every secret, had escaped in a lifeboat through the fine–meshed net set to catch him! And, piling Ossa upon Pelion, this same Lensman had—must have—captured ship after unconquerable ship of their best and was even now sailing calmly home with them! It was intolerable, unbearable, an insult that could not and would not be borne.
Therefore, using as tools every pirate ship in that sector of space, Helmuth and his computers and navigators were slowly but grimly solving the equations of motion of that volume of interference. Smaller and smaller became the uncertainties. Then ship after ship bored into the subethereal murk, to match course and velocity with, and ultimately to come to grips with, each focus of disturbance as it was determined.
Thus in a sense and although Kinnison and his friends did not then know it, it was only the failure of the Bergenholm that was to save their lives, and with those lives our present Civilization.
Slowly, hatingly, and, for reasons already given, undetected, Kinnison made pitiful progress toward Trenco, cursing impatiently and impartially his ship, the crippled generator, its designer and its previous operators as he went. But at long last Trenco loomed large beneath them and the Lensman used his Lens.
"Lensman of Trenco space–port, or any other Lensman within call!" he sent out clearly. "Kinnison of Tellus–Sol III—calling. My Bergenholm is almost out and I must sit down at Trenco space–port for repairs. I have avoided the pirates so far, but they may be either behind me or ahead of me, or both. What is the situation there?"
"I fear that I can be of no help," came back a weak thought, without the customary identification. "I am out of control. However, Tregonsee is in the …."
Kinnison felt a poignant, unbearably agonizing mental impact that jarred him to the very core, a shock that, while of sledge–hammer force, was still of such a keenly penetrant timbre that it almost exploded every cell of his brain. It seemed as though some mighty fist, armed with yard–long needles, had slugged an actual blow into the most vitally sensitive nerve–center" of his being.
Communication ceased, and the Lensman knew, with a sick, shuddering certainty, that while in the very act of talking to him a Lensman had died.
10: Trenco
Judged by any earthly standards the planet trenco was—and is—a peculiar one indeed. Its atmosphere, which is not sir, and its liquid, which is not water, are its two outstanding peculiarities and the sources of most of its others. Almost half of that atmosphere and by far the greater part of the liquid phase of the planet is a substance of extremely low latent heat of vaporization, with a boiling point such that during the daytime it is a vapor and at night a liquid. To make matters worse, the other constituents of Trenco's gaseous envelope are of very feeble blanketing power, low specific heat, and of high permeability, so that its days are intensely hot and its nights are bitterly cold.
At night, therefore, it rains. Words are entirely inadequate to describe to anyone who has never been there just how it does rain during Trenco' s nights. Upon Earth one inch of rainfall in an hour is a terrific downpour. Upon Trenco that amount of precipitation would scarcely be considered a mist, for along the equatorial belt, in less than thirteen Tellurian hours, it rains exactly forty– seven feet and five inches every night—no more no less, each and every night of every year.
Also there is lightning. Not in Terra's occasional flashes, but in one continuous, blinding glare which makes night as we know it unknown there in nerve–wracking, battering, sense–destroying discharges which make ether and sub– ether alike impenetrable to any ray or signal short of a full driven power beam. The days are practically as bad. The lightning is not violent then, but the bombardment of Trenco's monstrous sun, through that outlandishly peculiar atmosphere, produces almost the same effect.
