"No," and the Lensman tore up the check just as he had torn up the resignation. "If you want the stuff for legitimate purposes, you're on Patrol business and it is the Patrol's risk. If, on the other hand, you think that you're going to try to snuff a vortex, the stuff stays here. That's final, Storm."
"You're right--and wrong, Phil," Cloud stated, not at all sheepishly. "I'm going to blow out Number One vortex with duodec, yes--but I'm really going to blow it out, not merely make a stab at it as an excuse for suicide, as you think."
"How?" The big Lensman's query was skepticism incarnate. "It can't be done, except by an almost impossibly fortuitous accident. You yourself have been the most bitterly opposed of us all to these suicidal attempts."
"I know it--I didn't have the solution myself until a few hours ago--it hit me all at once. Funny I never thought of it before; it's been right in sight all the time."
"That's the way with most problems," the Chief admitted. "Plain enough after you see the key equation. Well, I'm perfectly willing to be convinced, but I warn you that I'll take a lot of convincing--and someone else will do the work, not you."
"When I get done you'll see why I'll pretty nearly have to do it myself. But to convince you, exactly what is the knot?"
"Variability," snapped the older man. "To be effective, the charge of explosive at the moment of impact must match, within very close limits, the activity of the vortex itself. Too small a charge scatters it around, in vortices which, while much smaller than the original, are still large enough to be self-sustaining. Too large a charge simply rekindles the original vortex--still larger--in its original crater. And the activity that must be matched varies so tremendously, in magnitude, maxima, and minima, and the cycle is so erratic--ranging from seconds to hours without discoverable rhyme or reason--that all attempts to do so at any predetermined instant have failed completely. Why, even Kinnison and Cardynge and the Conference of Scientists couldn't solve it, any more than they could work out a tractor beam that could be used as a tow-line on one."
"Not exactly," Cloud demurred. "They found that it could be forecast, for a few seconds at least--length of time directly proportional to the length of the cycle in question--by an extension of the calculus of warped surfaces."
"Humph!" the Lensman snorted. "So what? What good is a ten-second forecast when it takes a calculating machine an hour to solve the equations.... Oh!" He broke off, staring.
"Oh," he repeated, slowly, "I forgot that you're a lightning calculator--a mathematical prodigy from the day you were born--who never has to use a calculating machine even to compute an orbit.... But there are other things."
"I'll say there are; plenty of them. I'd thought of the calculator angle before, of course, but there was a worse thing than variability to contend with...."
"What?" the Lensman demanded.
"Fear," Cloud replied, crisply. "At the thought of a hand-to-hand battle with a vortex my brain froze solid. Fear--the sheer, stark, natural human fear of death, that robs a man of the fine edge of control and brings on the very death that he is trying so hard to avoid. That's what had me stopped."
"Right ... you may be right," the Lensman pondered, his fingers drumming quietly upon his desk. "And you are not afraid of death--now--even subconsciously. But tell me, Storm, please, that you won't invite it."
"I will not invite it, sir, now that I've got a job to do. But that's as far as I'll go in promising. I won't make any superhuman effort to avoid it. I'll take all due precautions, for the sake of the job, but if it gets me, what the hell? The quicker it does, the better--the sooner I'll be with Jo."
"You believe that?"
"Implicitly."
"The vortices are as good as gone, then. They haven't got any more chance than Boskone has of licking the Patrol."
"I'm afraid so," almost glumly. "The only way for it to get me is for me to make a mistake, and I don't feel any coming on."
"But what's your angle?" the Lensman asked, interest lighting his eyes. "You can't use the customary attack; your time will be too short."
"Like this," and, taking down a sheet of drafting paper, Cloud sketched rapidly. "This is the crater, here, with the vortex at the bottom, there. From the observers' instruments or from a shielded set-up of my own I get my data on mass, emission, maxima, minima, and so on. Then I have them make me three duodec bombs--one on the mark of the activity I'm figuring on shooting at, and one each five percent over and under that figure--cased in neocarballoy of exactly the computed thickness to last until it gets to the center of the vortex. Then I take off in a flying suit, armored and shielded, say about here...."
"If you take off at all, you'll take off in a suit, inside a one-man flitter," the Lensman interrupted. "Too many instruments for a suit, to say nothing of bombs, and you'll need more screen than a suit can deliver. We can adapt a flitter for bomb-throwing easily enough."
"QX; that would be better, of course. In that case, I set my flitter into a projectile trajectory like this, whose objective is the center of the vortex, there. See? Ten seconds or so away, at about this point, I take my instantaneous readings, solve the equations at that particular warped surface for some certain zero time...."
"But suppose that the cycle won't give you a ten-second solution?"
"Then I'll swing around and try again until a long cycle does show up."
"QX. It will, sometime."
"Sure. Then, having everything set for zero time, and assuming that the activity is somewhere near my postulated value...."
"Assume that it isn't--it probably won't be," the Chief grunted.
"I accelerate or decelerate--"
"Solving new equations all the while?"
"Sure--don't interrupt so--until at zero time the activity, extrapolated to zero time, matches one of my bombs. I cut that bomb loose, shoot myself off in a sharp curve, and Z-W-E-E-E-T--POWIE! She's out!" With an expressive, sweeping gesture.
"You hope," the Lensman was frankly dubious. "And there you are, right in the middle of that explosion, with two duodec bombs outside your armor--or just inside your flitter."
"Oh, no. I've shot them away several seconds ago, so that they explode somewhere else, nowhere near me."
"I hope. But do you realize just how busy a man you are going to be during those ten or twelve seconds?"
"Fully." Cloud's face grew somber. "But I will be in full control. I won't be afraid of anything that can happen--anything. And," he went on, under his breath, "that's the hell of it."
"QX," the Lensman admitted finally, "you can go. There are a lot of things you haven't mentioned, but you'll probably be able to work them out as you go along. I think I'll go out and work with the boys in the lookout station while you're doing your stuff. When are you figuring on starting?"
"How long will it take to get the flitter ready?"
"A couple of days. Say we meet you there Saturday morning?"
"Saturday the tenth, at eight o'clock. I'll be there."

And again Neal Cloud and Babe, the big blue ox, hit the road. And as he rolled the physicist mulled over in his mind the assignment to which he had set himself.
Like fire, only worse, intra-atomic energy was a good servant, but a terrible master. Man had liberated it before he could really control it. In fact, control was not yet, and perhaps never would be, perfect. Up to a certain size and activity, yes. They, the millions upon millions of self-limiting ones, were the servants. They could be handled, fenced in, controlled; indeed, if they were not kept under an exciting bombardment and very carefully fed, they would go out. But at long intervals, for some one of a dozen reasons--science knew so little, fundamentally, of the true inwardness of the intra-atomic reactions--one of these small, tame, self-limiting vortices flared, nova-like, into a large, wild, self-sustaining one. It ceased being a servant then, and became a master. Such flare-ups occurred, perhaps, only once or twice in a century on Earth; the trouble was that they were so utterly, damnably permanent
. They never went out. And no data were ever secured: for every living thing in the vicinity of a flare-up died; every instrument and every other solid thing within a radius of a hundred feet melted down into the reeking, boiling slag of its crater.
Fortunately, the rate of growth was slow--as slow, almost, as it was persistent--otherwise Civilization would scarcely have had a planet left. And unless something could be done about loose vortices before too many years, the consequences would be really serious. That was why his laboratory had been established in the first place.
Nothing much had been accomplished so far. The tractor beam that would take hold of them had never been designed. Nothing material was of any use; it melted. Pressors worked, after a fashion: it was by the use of these beams that they shoved the vortices around, off into the waste places--unless it proved cheaper to allow the places where they had come into being to remain waste places. A few, through sheer luck, had been blown into self-limiting bits by duodec. Duodecaplylatomate, the most powerful, the most frightfully detonant explosive ever invented upon all the known planets of the First Galaxy. But duodec had taken an awful toll of life. Also, since it usually scattered a vortex instead of extinguishing it, duodec had actually caused far more damage than it had cured.
No end of fantastic schemes had been proposed, of course; of varying degrees of fantasy. Some of them sounded almost practical. Some of them had been tried; some of them were still being tried. Some, such as the perennially-appearing one of building a huge hemispherical hull in the ground under and around the vortex, installing an inertialess drive, and shooting the whole neighborhood out into space, were perhaps feasible from an engineering standpoint. They were, however, potentially so capable of making things worse that they would not be tried save as last-ditch measures. In short, the control of loose vortices was very much an unsolved problem.
* * * * *
Number One vortex, the oldest and worst upon Tellus, had been pushed out into the Badlands; and there, at eight o'clock on the tenth, Cloud started to work upon it.
The "lookout station," instead of being some such ramshackle structure as might have been deduced from the Lensman's casual terminology, was in fact a fully-equipped observatory. Its staff was not large--eight men worked in three staggered eight-hour shifts of two men each--but the instruments! To develop them had required hundreds of man-years of time and near-miracles of research, not the least of the problems having been that of developing shielded conductors capable of carrying truly through five-ply screens of force the converted impulses of the very radiations against which those screens were most effective. For the observatory, and the one long approach to it as well, had to be screened heavily; without such protection no life could exist there.
This problem and many others had been solved, however, and there the instruments were. Every phase and factor of the vortex's existence and activity were measured and recorded continuously, throughout every minute of every day of every year. And all of these records were summed up, integrated, into the "Sigma" curve. This curve, while only an incredibly and senselessly tortuous line to the layman's eye, was a veritable mine of information to the initiate.
Cloud glanced along the Sigma curve of the previous forty-eight hours and scowled, for one jagged peak, scarcely an hour old, actually punched through the top line of the chart.
"Bad, huh, Frank?" he grunted.
"Plenty bad, Storm, and getting worse," the observer assented. "I wouldn't wonder if Carlowitz were right, after all--if she ain't getting ready to blow her top I'm a Zabriskan fontema's maiden aunt."
"No periodicity--no equation, of course." It was a statement, not a question. The Lensman ignored as completely as did the observer, if not as flippantly, the distinct possibility that at any moment the observatory and all that it contained might be resolved into their component atoms.
"None whatever," came flatly from Cloud. He did not need to spend hours at a calculating machine; at one glance he knew, without knowing how he knew, that no equation could be made to fit even the weighted-average locus of that wildly-shifting Sigma curve. "But most of the cycles cut this ordinate here--seven fifty-one--so I'll take that for my value. That means nine point nine oh six kilograms of duodec basic charge, with one five percent over and one five percent under that for alternates. Neocarballoy casing, fifty-three millimeters on the basic, others in proportion. On the wire?"
"It went out as you said it," the observer reported. "They'll have 'em here in fifteen minutes."
"QX--I'll get dressed, then."
The Lensman and the observer helped him into his cumbersome, heavily-padded armor. They checked his instruments, making sure that the protective devices of the suit were functioning at full efficiency. Then all three went out to the flitter. A tiny speedster, really; a torpedo bearing the stubby wings and the ludicrous tail-surfaces, the multifarious driving-, braking-, side-, top-, and under-jets so characteristic of the tricky, cranky, but ultra-maneuverable breed. But this one had something that the ordinary speedster or flitter did not carry; spaced around the needle beak there yawned the open muzzles of a triplex bomb-thrower.
More checking. The Lensman and the armored Cloud both knew that every one of the dozens of instruments upon the flitter's special board was right to the hair; nevertheless each one was compared with the master-instrument of the observatory.
* * * * *
The bombs arrived and were loaded in; and Cloud, with a casually-waved salute, stepped into the tiny operating compartment. The massive door--flitters have no airlocks, as the whole midsection is scarcely bigger than an airlock would have to be--rammed shut upon its fiber gaskets, the heavy toggles drove home. A cushioned form closed in upon the pilot, leaving only his arms and lower legs free.
Then, making sure that his two companions had ducked for cover, Cloud shot his flitter into the air and toward the seething inferno which was Loose Atomic Vortex Number One. For it was seething, no fooling; and it was an inferno. The crater was a ragged, jagged hole a full mile from lip to lip and perhaps a quarter of that in depth. It was not, however, a perfect cone, for the floor, being largely incandescently molten, was practically level except for a depression at the center, where the actual vortex lay. The walls of the pit were steeply, unstably irregular, varying in pitch and shape with the hardness and refractoriness of the strata composing them. Now a section would glare into an unbearably blinding white puffing away in sparkling vapor. Again, cooled by an inrushing blast of air, it would subside into an angry scarlet, its surface crawling in a sluggish flow of lava. Occasionally a part of the wall might even go black, into pock-marked scoriae or into brilliant planes of obsidian.
For always, somewhere, there was an enormous volume of air pouring into that crater. It rushed in as ordinary air. It came out, however, in a ragingly-uprushing pillar, as--as something else. No one knew--or knows yet, for that matter--exactly what a loose vortex does to the molecules and atoms of air. In fact, due to the extreme variability already referred to, it probably does not do the same thing for more than an instant at a time.
That there is little actual combustion is certain; that is, except for the forced combination of nitrogen, argon, xenon, and krypton with oxygen. There is, however, consumption: plenty of consumption. And what that incredibly intense bombardment impinges up is ... is altered. Profoundly and obscuredly altered, so that the atmosphere emitted from the crater is quite definitely no longer air as we know it. It may be corrosive, it may be poisonous in one or another of a hundred fashions, it may be merely new and different; but it is no longer the air which we human beings are used to breathing. And it is this fact, rather than the destruction of the planet itself, which would end the possibility of life upon Earth's surface.

It is difficult indeed to describe the appearance of a loose atomic vortex to those who have never seen one; and, fortunately, most people never have. And practically all of its frightful radiation lies in those octaves of the spectrum which are in
visible to the human eye. Suffice it to say, then, that it had an average effective surface temperature of about fifteen thousand degrees absolute--two and one-half times as hot as the sun of Tellus--and that it was radiating every frequency possible to that incomprehensible temperature, and let it go at that.
And Neal Cloud, scurrying in his flitter through that murky, radiation-riddled atmosphere, setting up equations from the readings of his various meters and gauges and solving those equations almost instantaneously in his mathematical-prodigy's mind, sat appalled. For the activity level was, and even in its lowest dips remained, far above the level he had selected. His skin began to prickle and to burn. His eyes began to smart and to ache. He knew what those symptoms meant; even the flitter's powerful screens were not stopping all the radiation; even his suit-screens and his special goggles were not stopping what leaked through. But he wouldn't quit yet; the activity might--probably would--take a nose-dive any instant. If it did, he'd have to be ready. On the other hand, it might blow up at any instant, too.
There were two schools of mathematical thought upon that point. One held that the vortex, without any essential change in its physical condition or nature, would keep on growing bigger. Indefinitely, until, uniting with the other vortices of the planet, it had converted the entire mass of the world into energy.
The second school, of which the forementioned Carlowitz was the loudest voice, taught that at a certain stage of development the internal energy of the vortex would become so great that generation-radiation equilibrium could not be maintained. This would, of course, result in an explosion; the nature and consequences of which this Carlowitz was wont to dwell upon in ghoulishly mathematical glee. Neither school, however, could prove its point--or, rather, each school proved its point, by means of unimpeachable mathematics--and each hated and derided the other, loudly and heatedly.
