"Spawn of the Comet" (1931) by Harold Thompson Rich, with Notes and Comments


"Spawn of the Comet"

Harold Thompson Rich  


Tokyo, June 10 (AP).—A number of the meteors that pelted Japan last night, as the earth passed through the tail of the Mystery Comet have been found and are puzzling astronomers everywhere.

About the size of baseballs, orange in color, they appear to be of some unknown metal. So far, due to their extreme hardness, all attempts to analyze them have failed.

Their uniformity of size and marking gives rise to the popular belief that they are seeds, and, fantastic though this conception  is, it finds support in certain scientific quarters here.

Jim Carter read the news dispatch thoughtfully and handed it back to his chief without comment.

“Well, what do you make of it?”

Miles Overton, city editor of The New York Press, shoved his green eye-shade far back on his bald head and glanced up irritably from his littered desk.

“I don’t know,” said Jim.

“You don’t know!” Overton snorted, biting his dead cigar impatiently. “And I suppose you don’t know they’re finding the damn things right here in New York, not to mention Chicago, London, Rio and a few other places,” he added.

“Yes, I know about New York. It’s a regular egg hunt.”

“Egg hunt is right! But why tell me all this now? I didn’t see any mention of ’em in your report of last night’s proceedings. Did you see any?”

“No, but I saw a lot of shooting stars!” said Jim, recalling that weird experience he and the rest of humanity had passed through so recently.

“Yeah, I’ll say!” Overton lit his wrecked cigar and dragged on it soothingly. “Now then, getting back to cases—what are these damn things, anyway? That’s what I’d like to know.”

“So would I,” said Jim. “Maybe they are seeds?”

Overton frowned. He was a solid man, not given to fancies. He had a paper to get out every day and that taxed his imagination to the limit. There was no gray matter left for any such idle musings as Jim suggested. What he wanted was facts, and he wanted them right away.

“Eggs will do!” he said. “Go out and get one—and find out what’s inside it.”

“Okay, Chief,” said Jim, but he knew it was a large order. “I’ll have one on your desk for breakfast!”

Then, with a grave face that denied his light words, he stepped from the city room on that fantastic assignment.

It was the television broadcast hour and crowds thronged the upper level of Radio Plaza, gazing, intently at the bulletin screen (1), as Jim Carter emerged from the Press tower.

News from the ends of the earth, in audio-picture form, flashed before their view; but only the reports on the strange meteors from the tail of 1947 (2), IV—so designated by astronomers because it was the fourth comet discovered that year—held their interest. Nothing since the great Antarctic gold rush of ’33 had so gripped the public as the dramatic arrival and startling behavior of this mysterious visitant from outer space.
Jim paused a moment, halfway across the Plaza, to take a look at the screen himself.

The substance of the Tokyo dispatch, supplemented by pictures of Japanese scientists working over the baffling orange spheres, had just gone off. Now came a flash from Berlin, in which a celebrated German chemist (3) was seen directing an effort to cut into one of them with an acid drill. It failed and the scientist turned to declare to the world that the substance seemed more like crystal than metal and was harder than diamond (4).

Jim tarried no longer. He knew where he was going. It was still early and Joan would be up—Joan Wentworth, daughter of Professor Stephen Wentworth (5), who held the chair of astro-lithology (6) at Hartford University. It was as their guest at the observatory last night that he had seen 1947, IV at close range,  as the earth passed through her golden train with that awesome, unparalleled display of fireworks.

Now he’d have the pleasure of seeing Joan again, and at the same time get the low-down from her father on those confounded seeds—or eggs, rather. If anyone could crack one of them, he’d bet Professor Wentworth could.

So, hastening toward the base of Plaza Airport, he took an elevator to ramp-level 118, where his auto-plane was parked, and five minutes later was winging his way to Hartford (7).

Throttle wide, Jim did the eighty miles to the Connecticut capital in a quarter of an hour.

Then, banking down through the warm June night onto the University landing field, he retracted the wings of his swift little bus and motored to the foot of Observatory Hill.

Parking outside the Wentworth home, he mounted the steps and rang the bell.

It was answered by a slim, appealing girl of perhaps twenty-two. Hers was a wistful, oval face, with a small, upturned nose; and her clear hazel eyes were the sort that always seem to be enjoying some amusing secret of their own. Her hair was a soft brown, worn loose to the shoulders, after the style then in vogue.

“Joan!” blurted Jim.

“What brings you here at such an hour, Jimmy Carter? (8)” she asked with mock severity.

“You!”

“I don’t believe you.”

“What then have I come for?”

“You’ve come to interview father about those meteorites.”

“Nonsense! That’s purely incidental—a mere by-product, you might say.”

“Yes, you might—but I wouldn’t advise you to say it to father.”

“All right, I won’t,” he promised, as she led him into the library.

Professor Wentworth rose as they entered and laid aside some scientific book he had been reading.

A man of medium height and build, he had the same twinkling hazel eyes as his daughter, though somewhat dimmed from peering at too many stars for too many years.

“Good evening, Jim,” he said. “I’ve rather been expecting you. What is on your mind?”

“Seeds! Eggs! Baseballs!” was the reply, “I don’t know what. You’ve seen the latest television reports, I suppose?” said Jim, noting that the panel on the receiving cabinet across the room was still lit.

“I’ve seen some of them. Joan has been keeping an eye on the screen mostly, however, while I refreshed my mind on the known chemistry of meteorites. You see, I have a few of those eggs myself, up at the observatory.”

“You have?” cried Jim.

He was certainly on the right track!

“Yes. One of my assistants brought them in this afternoon. Would you like to see them?”

“I’ll say I would!”

“I rather thought you might,” the professor smiled. “Come along, then.”

And as Jim turned, he shot a look at Joan, and added:

“You may come too, my dear, if you want.”

They went out and up the hill to where the great white dome glistened under the stars, and once inside, Jim Carter of The New York Press was privileged to see two of those strange objects that had turned the world topsy-turvy.

As the Tokyo dispatch and the Berlin television flash had indicated, they were orange in color, about the size of baseballs.

 “Weird looking eggs, all right!” said Jim. “What are they made of, anyway?”

“Some element unknown on earth,” replied Professor Wentworth.

“But I thought there were only ninety-two elements in the universe and we’d discovered them all.”

“So we have. But don’t forget this. We are still trying to split the atom, which nature has done many times and will doubtless do many times again. It is merely a matter of altering the valence of the atoms in an old element ; whereupon it shifts its position in the periodic scale and becomes a new element (9). Nature accomplishes this alchemy by means of great heat, which is certainly to be found in a meteor.” (10)

“Particularly when it hits the earth’s atmosphere!” (11)

“Yes. And now then, I’d like to have you examine more closely this pair I have here.”

Jim lifted one and noted its peculiar smoothness, its remarkable weight for its size; he noted, too, that it was veined with concentric markings, like a series of arabesques or fleurs-de-lis.

The professor lifted the other, calling attention to the fact that the size and marking of both were identical, as hitherto reported.

“Also, you’ll observe that they are slightly warm. In fact, they are appreciably warmer than when they were first brought in. Curious behavior, this, for new-laid cometary eggs! More like seeds germinating than meteorites cooling, wouldn’t you say?” (12)

“But good Lord!” Jim was somewhat taken aback to hear this celebrated scientist apparently commit himself to that wild view. “You don’t really think they’re seeds, do you?”

“Why not?”

“But surely no seeds could survive the temperature they hit getting here.”

“No seeds such as we know, true. But what, after all, do we know of the types of life to be found on other planets?” (13)

“Nothing, of course. Only these didn’t come from a planet. They came from a comet.”

“And who can say a comet is not a disintegrated planet? Or suppose we take the other theory, that it is an eruption from some sun, ours or another (14). In any event, who can say no life can survive intense heat? Certainly these seeds—or call them meteorites, if you choose—came through the ordeal curiously unscathed.”

“Yes, that’s true. Funny, too!”

“And another thing is true, Jim. If by chance they should be seeds, and should germinate, the life they would produce would be something quite alien to our experience, possibly quite inimical to—”

Professor Wentworth broke off abruptly as a startled cry came from Joan, and, turning, they saw her standing with eyes fixed in fascinated horror on the laboratory table.

Following her gaze, Jim saw something that caused his own eyes to bulge. The color of those mysterious orange spheres had suddenly, ominously heightened. They lay glowing there like balls of fire.

“Good God!” he gasped. “Look, Professor! Do you see that?”

Professor Wentworth did not answer but himself stood gazing spellbound at the astounding scene.

Even as they looked, the metal table smoldered under the fiery meteorites and melted, and in a little while the meteorites themselves sizzled from view. Flames licked up from the floor; dense, suffocating fumes rose and swirled through the laboratory (15).

 “Quick!” cried Jim, seizing Joan’s arm. “Come on, Professor! Never mind trying to save anything. Let’s get out of here!”

They staggered from the laboratory and once outside, plunged down the hill. It was none too soon.

Behind them, as they fled, came suddenly two deafening explosions. Looking back, they saw the roof of the observatory tilt crazily; saw the whole building shatter, and erupt like a volcano.

But that, startling though it was, was not all they saw. For now, as they stood there speechless, two incredible forms rose phoenix-like from the flames—two weird monsters, orange against the red, hideous, nightmarish. They saw them hover a moment above that fiery hell, then rise on batlike wings to swoop off into the night.

Nor was that all. As the awed trio stood there halfway down Observatory Hill, following the flight of that pair of demons, other explosions reached their ears, and, turning to the city below, they saw vivid jets of red leap up here and there, saw other orange wings against the night.

While off across the southeast sky, receding fast, spread the Mystery Comet whose tail had sowed the seeds of this strange life.

Still silent, the trio stood gazing upon that appalling scene for some minutes, while the ruddy shadows of the flaming observatory lit their tense faces.

“Well, the seeds have hatched,” said Professor Wentworth at length, in a strained voice. “I am afraid some of the curious who have been gathering those meteorites so eagerly have paid a dear price for them.”

“Yes, I’m afraid so,” echoed Jim. “We were lucky. If Joan hadn’t happened to spot those things just when she did—” He broke off and pressed her hand fondly. “But somehow I can’t believe it, even yet. What do you think the things are, Professor?”

“God knows! As I told you, those seeds, should they germinate, would produce something quite alien to our experience; and as I feared, it is a form of life that will not blend well with humanity.”

Jim shuddered.

“But look, father!” exclaimed Joan. “They’re flying away! They seem to be way up among the stars. Maybe they’ve left the earth altogether.”

Professor Wentworth following his daughter’s gaze, saw that many of the monsters were now mere orange pinpoints against the night.

“Let us hope so!” he said fervently.

But in his heart there was no conviction, nor in Jim’s, strangely.

On the way back to New York, Jim had plenty to heighten his uneasiness. The scene below him everywhere was red with conflagrations, the sky everywhere orange with the wings of those fiery moths.

More than one swept perilously close, as he pushed his auto-plane on at top speed; but they showed no inclination to attack, for which he was devoutly thankful.

Over the metropolitan area, the scene was one beggaring description. All the five boroughs were a blazing checker-board. New Jersey, Connecticut, Westchester—all were raging. Hundreds of those deadly bombs must have burst in Manhattan alone.

But the fire department there seemed to have the situation in hand, he noticed as he swept down onto the Plaza landing platform.

Leaving his plane with an attendant, he took the first elevator to the street level, and crossing  hastily to the Press tower, mounted to the city room.

There absolute pandemonium raged. Typewriters were sputtering, telegraph keys clicking, phones buzzing, reporters coming and going in a steady stream, mingled with the frantic orders of editors, sub-editors, copy readers, composing-room men and others.

Carter fought through the bedlam to the city editor’s desk.

“Sorry I couldn’t bring you that egg, Chief,” he said, with a grim smile. “I had one right in my hand, but it hatched out on me.”

Overton looked up wearily. He was a man who had seen a miracle, a godless miracle that restored his faith in the devil.

“Don’t talk—just write!” he growled. “I’ve seen and heard too much to-night. We’re all going to hell, I guess—unless we’re already there.”

But Jim wasn’t ready to write yet.

“What’s the dope elsewhere? The same?”

“All over the map! We’re frying, from coast to coast.”

“And abroad?”

“Cooked, everywhere!” (16) He paused, and turned an imploring face to Jim. “Tell me, Carter—what’s happening? You’ve seen Wentworth, I suppose. What’s he make of it?”

“He—doesn’t know.”

“God help us! Well, go write your story. If we’ve got a plant by press time, we’ll have something on page one to-morrow—if there’s anyone to read it.”

By morning the fires in the metropolitan area had been brought under control and it was found that neither the loss of life nor the damage was as great as had at first been feared. Mainly it was the older types of buildings that had suffered the most.

The same thing was true in other parts of the country and elsewhere in the world; and elsewhere, as in New York, people pulled themselves together, cleared up the debris, and went ahead with their occupations. Business was resumed, and rebuilding operations were begun (17).

Meanwhile, where were those fiery moths that had sprung so devastatingly from their strange cocoons?

For a while no one knew and it was believed they had indeed winged off into interstellar space, as Joan had suggested that night on Observatory Hill.

Then came rumors that damped these hopes, followed by eye-witness reports that altogether dashed them. The bat-like monsters had flown, not off into space, but to the world’s waste-lands.

Strange, it was, the instinct that had led them unerringly to the remotest point of each continent. In North America it was the great Arizona desert, in South America the pampas of Argentina, in Europe the steppes of Russia, in Asia the Desert of Gobi, in Africa the Sahara, in Australia the Victoria; while in the British Isles, Philippines, New Zealand, Madagascar, Iceland, the East Indies, West Indies, South Seas and other islands of the world, the interiors were taken over by the demons, the populace fleeing for their lives (18).

As for the oceans, no one knew exactly what had happened there, though it was obvious they, too, had received their share of the bombardment on that fateful night; but, while temperatures were found to be somewhat above normal, scientists were of the opinion that the deadly spawn that had fallen there had failed to incubate.

Immediately the presence of the monsters in the Arizona desert was verified, Overton called Jim Carter to his desk.

 “Well, I’ve got a big assignment for you, boy,” he said, rather more gently than was his fashion. “Maybe you know what, huh?”

“You want me to buzz out and interview those birds?” (19)

“You guessed it. And photograph ’em!”

“Okay, Chief,” said Carter, though he knew this would be the toughest job yet.

Overton knew it, too.

“It won’t be easy,” he said. “And it may be dangerous. You don’t have to take the assignment unless you want.”

“But I want.”

“Good! I thought you would.” He regarded the younger man admiringly, almost enviously. “Now, about those photos. The Television News people haven’t been able to get a thing, nor the War Department—not so much as a still. So those photos will be valuable.”

Overton paused, to let that sink in.

“They’ll be worth a million, in fact, in addition to what the War Department offers. And to you they’ll be worth ten thousand dollars.”

“How come?”

“Because that’s what the Old Man said.”

“Well, I can use it!” said Jim, thinking of Joan.

“All right. Then go to it!”

Leaving New York late that night, Carter timed his flight to arrive over the eastern edge of the desert just before dawn.

The trip was uneventful till he crossed the Rockies over New Mexico and eased down into Arizona. Then, flying low and fast, he suddenly caught a glow of color off ahead.

For an instant Jim thought it was the dawn, then called himself a fool. For one thing, the glow was in the west, not the east. And for another, altogether more significant, it was orange.

His quarry!

Pulling his stick back hard, he shot like a rocket to ten thousand feet, figuring that a higher altitude, besides giving him a better view of the lay of the land, would be considerably safer.

Winging on now at that height, he saw the orange tide rise higher in the west by seconds, as he rushed toward God knew what eery lair. He suddenly gasped in amazement, as he saw now something so incredible it left him numb.

Below, looming above the on-rushing horizon was a city! But such a city as the brain of man could scarcely conceive, much less execute—a city of some fluorescent orange material, rising tier on tier, level on level, spreading out over the sandy floor of the desert for miles.

And, as Jim draw nearer, he saw, too, that this weird city was teeming with life—terrible life! Thousands of those hideous monsters were working there like an army of ants in a sand-hill—a sand-hill of glistening, molten glass, it seemed from the air.

Were they building their city from the sand of the desert, these hellish glaciers?

Carter decided to find out.

“Well, here goes!” he muttered, diving straight for that dazzling citadel, one hand on the stick, the other gripping the trigger of his automatic camera. “This’ll make a picture for the Old Man, all right!”

Off to the east the dawn was breaking, and he saw, as he swept down, its pearly pastel shades blending weirdly with that blinding orange glare.

Pressing the trigger now, he drove his screaming plane on with throttle wide—and yes, it was glass!—glass of some sort, that crazy nightmare down there.

 “Whew!” gasped Carter as waves of dazing heat rose about him. “Boy, but it’s hot! I can’t stand much of this. Better get out while the getting’s good.”

But he clenched his teeth, and dove on down to see what those fiery demons looked like. Funny they didn’t make any effort to attack. Surely they must see him now.

“Take that, my beauties!—and that!” he gasped, pressing the trigger of his camera furiously.

Then, at a scant two thousand feet, he levelled off, his wings blistering with the heat, and zoomed up again—when to his horror, his engine faltered; died.

In that agonizing moment it came to Jim that this perhaps was why neither the Television News nor the War Department pilots had been able to get pictures of the hell below.

Had something about that daring heat killed their motors, too, as it had his? Had they plunged like fluttering, sizzling moths into that inferno of orange flame? (20)

“Well, I guess it’s curtains!” he muttered.

A glance at his altimeter showed a scant eighteen hundred now. Another glance showed the western boundary of the city, agonizing miles ahead. Could he make it? He’d try, anyway!

So, nursing his plane along in a shallow glide, Jim slipped down through that dazing heat.

“Got to keep her speed up!” he told himself, half deliriously, as he steadily lost altitude. “Can’t pancake here, or I’ll be a flapjack!”

At an altitude of less than a thousand he levelled off again, eased on down, fully expecting to feel his plane burst into flames. But though his eyebrows crisped and the gas must have boiled, the sturdy little plane made it.

On a long last glide, he put her wheels down on the sandy desert floor, a bare half mile beyond that searing hell.

The heat was still terrific but endurable now. He dared breathe deeper; he found his head clearing. But what was the good of it? It was only a respite. The monsters had seen him, all right—no doubt about that! Already they were swooping out of their weird citadel like a pack of furious hornets (21).

On they came, incredibly fast, moving in a wide half-circle that obviously was planned to envelop him.

Tense with horror, like a doomed man at the stake, Jim watched the flaming phalanx advance. And now he saw what they really were; saw that his first, fantastic guess had been right.

They were ants—or at least more like ants than anything on earth—great fiery termites ten feet long, hideous mandibles snapping like steel, hot from the forge, their huge compound eyes burning like greenish electric fire in their livid orange sockets (22).

And another thing Jim saw, something that explained why the fearful insects had not flown up to attack him in the air. Their wings were gone! (23)

They had molted, were earthbound now.

There was much food for thought in this, but no time to think. Already the creatures were almost on him.
Jim turned his gaze from them and bent over his dials in a last frantic effort to get his motor started. The instinct of self-preservation was dominant now—and to his joy, suddenly the powerful little engine began to hum with life.

He drew one deep breath of infinite relief, then gave her the gun and whirled off down the desert  floor, the enraged horde after him.

For agonizing instants it was a nip-and-tuck race. Then as he felt his wheels lift, he pulled hard back on his stick, and swept up and away from the deadly claws that clutched after him in vain.

Climbing swiftly, Jim banked once, swept back, put the bead full on that scattering half-circle of fiery termites, and pressed the trigger of his automatic camera.

“There, babies!” he laughed grimly. “You’re in the Rogues’ Gallery now!”

Then, swinging off to the northeast, he continued to climb, giving that weird ant-hill a wide berth.

Funny, about those things losing their wings, he was thinking now. Would they grow them again, or were they on the ground for good? And what was their game out there in the desert, anyway?

Questions Jim couldn’t answer, of course. Only time would tell. Meanwhile, he had some pictures that would make the Old Man sit up and take notice, not to mention the War Department.

“They’d better get the Army on the job before those babies get air-minded again!” he told himself, as he winged on into the rising sun. “Otherwise the show they’ve already staged may be only a little curtain-raiser.”
Jim’s arrival in the city room of The New York Press that afternoon was a triumphant one, for he had radio-phoned the story ahead and extras were out all over the metropolitan area, with relays flashing from the front pages of papers everywhere.

No sooner had he turned over his precious pictures to the photographic department for development than Overton rushed him to a microphone, and made him repeat his experience for the television screen.

But the city editor’s enthusiasm died when the negatives came out of the developer.

“There are your pictures!” he said, handing over a bunch of them.

Carter looked at them in dismay. They were all blank—just so much plain black celluloid.

“Over-exposed!” rasped Overton. “A hell of a photographer you are!”

“I sure am!” Jim agreed, still gazing ruefully at the ruined negatives. “Funny, though. The camera was checked before I started. I had the range before I pulled the trigger, every shot.” He paused, then added, as though reluctant to excuse himself: “It must have been the heat.”

“Yeah. I suppose so! Well, that was damn expensive heat for you, my lad. It cost you ten thousand bucks.”
“Yes, but—”

Jim had been going to say it had nearly cost him his life but thought better of it. Besides, an idea had come.

“Give me those negatives!” he said, “I’m going to find out what’s wrong with ’em.”

And since they were of no use to Overton, he gave them to Jim.

That night again, Jim Carter presented himself at the Wentworth home in Hartford, and again it was Joan who admitted him.

“Oh, Jimmy!” she murmured, as he took her in his arms. “We’re all so proud of you!”

“I’m glad someone is,” he said.

“But what a fearful risk you ran! If you hadn’t been able to get your motor started—”

“Why think of unpleasant things?” he said with a smile.

Then they went into the library, where Professor Wentworth added his congratulations.

“But I’m afraid I didn’t accomplish much,” said Jim, explaining about the pictures.

 “Let me see them,” said the professor.

Jim handed them over.

For a moment or two Professor Wentworth examined them intently, holding them this way and that.

“They indeed appear to be extremely over-exposed,” he admitted at length. “Your Fire Ants are doubtless radio-active to a high degree. The results could not have been much worse had you tried to photograph the sun direct.” (24)

“I thought as much,” said Carter, gloomily.

“But possibly the damage isn’t irreparable. Suppose we try re-developing a few of these negatives.”

He led the way to his study, which since the destruction of the observatory had been converted into a temporary laboratory.

Ten minutes later, Professor Wentworth had his re-developing bath ready in a porcelain basin and had plunged some of the negatives into it.

“This process is what photographers call intensification,” he explained. “It consists chemically in the oxidation of a part of the silver of which the image is composed. I have here in solution uranium nitrate, plus potassium ferricyanide acidified with acetic acid. The latter salt, in the presence of the acid, is an oxidizing agent, and, when applied to the image, produces silver oxide, which with the excess of acetic acid forms silver acetate.”

“Which is all so much Greek to me!” said Carter.

“At the same time, the ferricyanide is reduced to ferrocyanide,” the professor went on, with a smile at Joan, “whereupon insoluble red uranium ferrocyanide is produced, and, while some of the silver, in being oxidized by this process, is rendered soluble and removed from the negative into the solution, it is replaced by the highly non-actinic and insoluble uranium compound.” (26)

The process was one quite familiar to photographers experienced in astronomical work, he explained. In fifteen minutes they should know what results they were getting.

But when fifteen minutes passed and the negatives were still as black as ever, Jim’s hope waned.

Not so Professor Wentworth’s, however.

“There is a definite but slow reaction taking place,” he said after a careful examination. “Either the over-exposure is even greater than I had suspected, or the actinic rays from your interesting subjects have formed a stubborn chemical union with the silver of the image. In the latter event, which is the theory I am going to work on, we must speed up the reaction and tear some of that excess silver off, if we’re ever to see what is underneath.”

“But how are you going to speed up the reaction?” asked Jim. “I thought that uranium was pretty strong stuff by itself.”

“It is, but not as strong as this new substance we have in combination with the silver here. So I think I’ll try a little electrolysis—or, in plain English, electro-plating.”

As he spoke, the professor clipped a couple of platinum electrodes to the basin, one at each end. To the anode he attached one of the negatives, to the cathode a small piece of iron.

“Now then, we’ll soon see.”

He passed a low current into the wires, through a rheostat, with startling results. There was a sudden foaming of the solution and a weird vapor rose from it, luminous, milky, faintly orange.

For a moment, all they could do was stare.

Then Professor Wentworth switched off the current and stepped toward the tank. Waving away that  orange gas, he reached for the cathode and held it up. It was no longer iron, but silver, now.

“Plated, you see!” he exclaimed in triumph.

“Yes, but those fumes!” cried Jim. “Why, they were the same color as the—the Fire Ants, as you call them.”

“I know.” The professor was not as calm as he pretended. “We have released some of their actinic rays captured by the negative, in prying loose our excess silver (26). Later I shall repeat the process and capture some of that vapor for analysis. At present, let us have a look at the negative already treated.”

He lifted the anode from the solution now, removed the negative, and held it up. A smile of satisfaction broke over his face, followed by a shudder.

“There you are, Jim! Have a look!”

Jim looked, with Joan peering over his shoulder, and his pulses tingled. It was a clear shot of that scattering half-circle of fiery termites, taken after he got away and swept back over them.

“Say, that’s wonderful!” he exclaimed.

“Wonderful—but horrible!” echoed Joan.

“I’ll admit they’re not much on looks,” laughed Carter. “But their homely maps are worth a lot to me—ten thousand dollars, in fact!”

He told her why, and what he proposed to do with the money, and Joan thought it a very good idea.

While this was taking place, Professor Wentworth was re-developing the rest of the negatives.

At last all had been salvaged, even those taken in the terrific heat over that weird glass city out there, and Jim was preparing to bear them back to Overton in triumph.

He had thanked the kindly professor from the bottom of his heart, had even told him something of what he had been telling Joan. There remained but to put one last question, then go.

“Summing it all up, what do you make of those nightmares?” he asked. “Do you think they can be destroyed?”

Professor Wentworth did not reply at once.

“I can perhaps answer your question better when I have analyzed this specimen of gas,” he said at length, holding up a test-tube in which swirled a quantity of that luminous, milky orange vapor. “But if you wish to quote me for publication, you may say that when I have learned the nature of it, I shall devote all my energies to combating the menace it constitutes.”

And that was the message Jim took back with him, but it was the pictures that interested the practical Overton most.

Before many days, however, Overton, with the rest of the world, was turning anxiously to Professor Wentworth, watching his every move, awaiting his every word. For before many days terrible reports started coming in, not only from the Arizona desert but from the assembly grounds of the Fire Ants everywhere.

Those deadly termites were on the move! They were spreading from their central citadels in ominous, expanding circles—circles that engulfed villages, towns and cities in a swift, relentless ring of annihilation that was fairly stupefying.

In North America, the cities of Phoenix, Tucson and Prescott, with all that lay between, were already gone, their frantic populaces fleeing to the four points of the compass before that fateful orange tide. In South America, Rosario and Cordoba were within the flaming  ring and Buenos Aires was threatened. In Europe, Moscow and its vast tributary plain had fallen before the invaders. In Asia, a veritable inland empire was theirs, reaching from Urga to the Khingan Mountains. In Africa, Southern Algeria and French Sudan, with their innumerable small villages and oases, were overrun. In Australia, Coolgardie had succumbed and Perth was in a panic (27).

But fearful though the destruction was on the continents, it was the islands of the world that suffered most (28). First the smallest, those picturesque green gems of the South Seas, crisped and perished. Then came reports of the doom of the Hawaiian group, the Philippines, the East and West Indies, New Zealand, Tasmania and a score of others, their populations perishing by the thousands, as shipping proved unavailable to transport them to safety.

By far the most tragic fate, however, was that suffered by the British Isles. What happened there stunned the world, and brought realization to humanity that unless some miracle intervened, it was but a mirror of the doom that awaited all. For England, Ireland and Scotland were habitable no more. London, Dublin, Glasgow—all their proud cities, all their peaceful hamlets, centuries old, were flaming ruins.

Out of a population, of some sixty millions, it was estimated that at least eight millions must have perished. The rest, by prodigious feats of transportation, managed to reach the mainland, where they spread as refugees throughout an apprehensive, demoralized Europe.

As for the armies and navies of the world, they were powerless before this fiendish invader. Hammered with high explosives, drenched with chemicals, sprayed with machine-gun ballets, the fiery termites surged on unchecked, in ever-widening circles of death.

Lead and steel passed through them harmlessly. Gas wafted off them like air. Despite the frantic efforts of scientists and military men, nothing could be devised to stem that all-devouring orange tide.

It was quite obvious by now, even to the most conservative minds, that the end of human life on earth was not far off. It could only be a few more weeks before the last stronghold fell. Daily, hourly, those deadly Fire Ants were everywhere expanding their fields of operations. Presently all humanity would be driven to the seacoasts, there to perish by fire or water, as they chose.

There were some optimists, of course, who believed that the miracle would happen—that Professor Wentworth or some other scientist would devise some means of repelling the invader before it was too late.

Young Jim Carter of The York Press was not among them, however, though he would have gambled it would be Professor Wentworth if anyone. For what hope was there that any mere man could figure out a weapon that would be effective against such a deadly, such a superhuman foe?

Very little, it seemed, and he grew less and less sanguine, as he continued his frenzied, sleepless work of reporting the unending catastrophes for his paper.

He often thought bitterly of that ten thousand dollars. A lot of good that would do him now!

As for Joan, she faced her fate with fortitude—fortitude and a supreme faith that her father would succeed in analyzing that sinister orange vapor and find the weapon the world waited for.

But agonizing days passed and he did not find it.

 Then at last, on the night of August 14th, when Los Angeles and San Francisco were smoldering infernos, along with Reno, Denver, Omaha, El Paso and a score of other great American cities; when Buenos Aires and Santiago were gone, Berlin and Peking and Cairo; when Australia was all one fiery hell—then it was that Professor Wentworth summoned Jim Carter to Hartford.

Hoping against hope, he hurried over.

Once again, Joan ushered him into the house. She was very pale and did not speak.

At her side stood her father. It was he who spoke.

“Good evening, Jim. You have come promptly.”

His voice was strained, his face grave. He had aged greatly in the past few weeks.

“Well I’ll admit I clipped along. You’ve—found something?”

Professor Wentworth smiled wanly.

“Suppose you step into my study and see what I have found.”

He led the way toward the little makeshift laboratory that for many days and nights had been the scene of his efforts.

It was littered with strange devices now, strangest of all perhaps a huge glass tube like a cannon, mounted on some sort of swivel base.

Ignoring this for the moment, he turned to a smaller tube set upright on a table at the far end of the room. In it, glowed a sinister orange lump that made the whole tube fluorescent.

“Behold one of your monsters in captivity!” said the professor, again with a wan smile. “In miniature, of course. What I have done is to condense some of that vapor into a solid.”

The process, he explained, was similar to that employed by Madame Curie in obtaining metallic radium—electrolyzing a radium chloride solution with mercury as a cathode, then driving off the mercury by heat in a current of hydrogen—only he had used the new element instead of radium.

“Incidentally, I have learned that this new element is far more radioactive than radium and possesses many curious properties. Among them, it decomposes violently in water—particularly salt water—producing harmless hydrogen and chloride compounds. So we have nothing to fear from those seeds that fell in our oceans, lakes and rivers.” (28)

“Well, that’s something, anyway,” said Jim. “But have you found any way to combat the ones that have already hatched?”

“Before I answer that question,” Professor Wentworth replied, “I shall let you witness a little demonstration.”

He advanced to the cannon-like device at the other end of the room, swung it on its swivel till it was pointing directly at that fluorescent orange tube on the table.

“Watch closely!” he said, throwing a switch.

There was a sudden, whining hum in the air and the nib of the big tube glowed a soft, velvety green. Jim gazed at the scene with rapt attention.

“Don’t look at that one!” whispered Joan. “Look at the other!”

Jim did so, and saw that its fluorescence was waning.

A moment more the professor held the current on, while the tube grew white. Then he threw off the switch.

“Now let us have a look at our captive,” he said, striding over.

They followed, and one glance told Jim what had happened. That sinister lump of orange metal had vanished.
 
But where was it? That was what he wanted to know.

“A natural question, but not one easy to answer,” was Professor Wentworth’s reply. “I shall tell you what I have done; then you may judge for yourself.”

The cannon-like device which had accompanied the seeming miracle was an adaptation of the cathode tube, whose rays are identical with the beta rays of the atom and consist of a stream of negatively charged particles moving at the velocity of light—186,000 miles a second. These rays, in theory, have the power to combine with the positively charged alpha rays of the atom and drag them from their electrons, causing them to discharge their full quanta of energy at once, in the form of complete disintegration—and it was this theory the professor had acted on (30).

“But, good Lord—that’s splitting the atom!” exclaimed Jim. “You don’t mean to say you’ve done that?”

“I apparently have,” was the grave admission. “But do not let it seem such a miracle. Bear in mind, as I have pointed out before, that nature has accomplished this alchemy many times. All radio-active elements are evidences of it. The feat consists merely in altering the valence of the atom, changing its electric charge, in other words. What I have done in the present instance is merely to speed up a process nature already had under way, inasmuch as we are dealing with a radio-active substance.”

“But what has happened to the by-product of the reaction?”

“Your guess is as good as mine. I have not had time to study that phase of it. Heat, mainly, was produced. Possibly a few atoms of helium. But the substance is gone. That is our chief concern just now.” (31)

It was only after abandoning chemical means and turning to physics that he had met with success, he said. Cathode rays had finally proved the key to the riddle.

“But do you think this thing will work on a big scale?” asked Jim regarding that fragile tube doubtfully.

Professor Wentworth hesitated before replying.

“I do not know,” he admitted, “but I intend to find out—to-night.”

Jim looked at him in amazement. “To-night?”

“Yes. Or rather, the experiment will be at dawn. If successful, this continent at least will be rid of the menace.”

Jim’s amazement turned to incredulity and a sudden fear gripped him. Had the strain of the past few weeks unbalanced the professor’s mind?

“But surely you can’t hope to wipe them out with one tube. Why, it would take hundreds.”

“No, only one. You see, I am going to place the tube in the center of the circle and direct its rays outward toward the circumference in a swinging radius.”

Whereupon, for a moment, Jim’s fear seemed confirmed.

“But, good God!” he exclaimed. “It couldn’t possibly be that powerful, could it?”

“I think it can be made to be,” was Professor Wentworth’s grave assurance. “The greatest power we know in the universe is radiant energy, which reaches us from the sun and the stars, traveling at the speed of light.”

“Like light rays, these heat rays can be focused, directed; and the beta rays of the cathode, traveling at the same velocity, can be made to ride these rays of radiant heat much as electric power rides radio waves. The giant, in short, can be made, to carry the dwarf, with his deadly little weapon. That, at least, is the theory I am acting on.” (32)

This somewhat allayed Jim’s fears—fears  that vanished when the professor went on to explain somewhat the working of his mechanism.

“But how are you going to get the thing out there?” he asked, picturing with a shudder the center of the flaming hell.

“I imagine the War Department will provide me with a volunteer plane and pilot for the purpose,” was the calm reply.

“And you will go?”

“Yes, I will go.”

Jim debated, but not for long.

“Well, you needn’t trouble the War Department. Here’s your volunteer pilot! The plane’s outside. When do we start?”

“But, my dear young man!” objected the professor. “I cannot permit you to make this sacrifice. It is suicide, sheer suicide.” (33)

“Is my life any more precious than yours, or that of some volunteer Army pilot?” Jim asked him.

“But there is Joan. If I fail—she must depend on you.”

“If you fail, Professor, Joan won’t need me or anyone, for long. No, I go. So let’s chuck the argument and get ready.”

“Oh, Jimmy!” sobbed Joan. “Jimmy!”

But her eyes, as they met his mistily, were lit with a proud splendor.

Two hours later, Jim Carter’s little auto-plane lifted into the night, and, with that precious tube mounted above the cabin, winged swiftly westward.
As on his former foray into that fiery realm, Jimmy timed his flight to arrive over the eastern edge of the Arizona desert just before dawn. Somewhere in that great sandy waste, they felt, there would be a place to set the plane down and get the ray going.

Professor Wentworth had broadcast the particulars of his tube to his scientific colleagues wherever humanity still remained, and the eyes of the world were on this flight. If successful, swift planes would bear similar tubes to the centers of the devastated regions elsewhere, and sweep outward with their deadly rays. The earth would be rid of this fiery invader. If it were not successful….

Jim preferred not to think of that, as he drove on into the night.

Crossing the Missouri River at dark and deserted Kansas City, they soon saw the eastern arc of that deadly orange circle loom on the horizon. To get over it safely, Jim rose to twenty thousand feet, but even there the heat, as they sped across the frontier into enemy territory, was terrific.

Anxiously he watched his revs and prayed for his motor to hold up. If it stopped now, they were cooked!

The sturdy engine purred on with scarcely a flutter, however, and soon they were behind the lines, in a region pitted with the smoldering fires of towns and cities.

It made them shudder, it presented such an appalling panorama of ruin. But at the same time, it strengthened their hope. For very few flares of orange gleamed now among the red. The main forces of the invader were at the front. That meant there should be a safe place to land somewhere.

An hour later, some miles beyond that weird glass citadel that had been their objective, they found a wide stretch of empty desert, and there Jim brought the little plane down to a faultless landing, just as dawn was lightening the east.

Stepping out, he drew a deep breath of relief. For had he crashed, or smashed that fragile tube, all would have been in vain.

“Well, here we are!” he exclaimed, grimly cheerful, as Professor  Wentworth stepped out after him. “Now let’s—”

Then he broke off, horrified, as he saw another figure follow the professor from the cabin.

“Joan!” he gasped.

“Present!” she replied.

“But, my daughter!” the professor’s voice broke in. “My dear child!” A sob shook him. “Why, why, this is—”

“Please don’t let’s talk about it!” she begged, giving his arm a little pat. “I’m here and it can’t be helped now. I was only afraid you’d find me before it was too late and take me back.”

Then, edging over to Jim and slipping her arm in his, she murmured:

“Oh, my dear! Don’t you see I couldn’t stay behind? I had to be with you at the end, Jimmy, if—” (34)

“It won’t be!” he cried, pressing her cold hand. “It can’t be!”

Then he turned to give his attention to her father, who had already mounted to the cockpit and was working absorbedly over his mechanism in the pale light of the coming day.

Any moment, Jim knew, those flaming termites might discover them, and come swooping down. With keen eyes he scanned the horizon. No sign of them yet.

“How are you up there?” he called.

“About ready,” was the reply. “But I shall want more light than this for my mirrors.”

Tensely, counting the seconds, they waited for the sunrise….

And now, as they waited, suddenly a sinister tinge of orange suffused the rosy hues of the east.

“The Fire Ants!” cried Joan, shrinking. “They’ve seen us! They’re coming!”

It was true, Jim saw with a heavy heart.

Turning to Professor Wentworth, he gasped out:

“Quick! We’ve got to do something! You’ve no idea how fast they move!”

“Very well.” The professor’s voice was strangely calm. “You may start your motor. I shall do what I can. Though if we only had the sun—”

Jim leaped for the cabin.

A touch of the starter and the powerful engine came in. Braking his wheels hard, to hold the plane on the ground, he advanced the throttle as much as he dared, and sent a high-tension current surging through the wires the professor had connected with his tube above (35).

Soon came that high, whining hum they had heard in the laboratory—a thousand times magnified now—and the nib of the big tube glowed a livid, eery green in the lemon dawn.

“Joan!” called her father sharply. “Get in the cabin with Jim!”

She did so, her eyes still fixed in horrified fascination on the eastern horizon; and in that tense instant, she saw two things. First, a great orange arc of fiery termites, bearing down on them; and second, another arc, far greater—the vast saffron rim of the rising sun.

Those two things Joan saw—and so did Jim—as their eardrums almost burst with the stupendous vibration that came from the gun in the cockpit. Then they saw a third, something that left them mute with awe.

As Professor Wentworth swung his cannon ray upon that advancing horde, it melted, vanished, leaving only the clear yellow of the morning sunlight before their bewildered eyes.

But the professor did not cease. For five minutes—ten, fifteen—he swung that mighty ray around, stepping up its power, lengthening  its range, as it reached its invisible, annihilating arm farther and farther out….

Meanwhile Jim was radio-phoning frantically. The air seemed strangely full of static.

At last he got Overton of The New York Press.

“Carter speaking, out in Arizona,” he said. “Getting any reports on the ray?”

And back came the tremendous news:

“Results! Man, the world’s crazy! They’re gone—everywhere! Tell the professor to lay off, before he sends us scooting too.”

“Right!” said Jim, cutting his motor. “More later!”

And to Professor Wentworth he called:

“All right, that’s enough! That ray was stronger than you knew!”

But there came no answer, and mounting to the wing-tip, Joan following, Jim saw a sight that froze him with horror. They beheld the professor, slumped against the tube, his whole body glowing a pale, fluorescent green (36).

“Father!” screamed Joan, rushing to his side. “Oh, Father!”

The man stirred, motioned her away, gasped weakly:

“Do not touch me, child—until the luminosity goes. I am highly radio-active (37). I had no time to—insulate the tube. No time to find out how. Had to—hurry—”

His voice waned off and they knew he was dead. The two stood there stunned by the realization of his great sacrifice.

He and Joan had set forth on this venture knowing they stood at least a chance, thought Jim, but Professor Wentworth had known from the start that it was sure death for him.

The sun stood out above the eastern horizon like a huge gold coin, bright with the promise of life to spend, when Jim and Joan took off at last for the return home; but the radiance of the morning was dimmed by the knowledge of the tragic burden they bore.

For some moments, as they winged on, both were silent.

“Look!” said Jim at length. “Look ahead, Joan!”

She looked, brightened somewhat.

“Yes, I see.”

And after a moment, lifting her hazel eyes to his, she said. “Oh, Jimmy, I’m sure it means happiness for us.”

“Yes, I’m sure!”

She stirred, moved closer.

“Jimmy, you—you’re all I have now.”

He made no reply, save to press her trembling hand. But it was enough.

Silently, understandingly, they winged onward into the morning light.

END.

NOTES
======

(1) - In the Interwar Era, it was generally assumed that near-future television would be broadcast to central locations such as large public screens, rather than to privately-owned television sets.  This was because TV was expensive experimental technology at this time, and most writers could not predict how rapidly the price would drop.  They also tended to assume that it would broadcast mostly public-interest news programs to be delivered to public squares, rather than light entertainment intended for home viewing.  One can see an example of these assumptions in action in the "2040" segment of Things to Come (1936), in which the citizens of Everytown assemble in the main town square to listen to Theotocopulos' exhortations to destroy the Space Gun.

(2) - Sixteen years in the future from the time of publication (1931).

(3) - From the mid-19th century through the end of World War II, Germany was a world leader in the development of chemistry.  This would end, of course, with the combination of Hitler driving the Jews out of German academic life and the immense damage to men and materiel caused by World War II.  In 1931, there was no way for any writer to reasonably predict these insane acts of German self-destruction:  Hitler himself would not come to power until 1933.  Hence, the writer almost certainly assumes that Germany has not fought any European wars between 1931 and 1947, and is thus still a major scientific Power.

(4) - Diamond was the hardest substance known then and the hardest naturally-occurring substance known now (some artificially-produed nanomaterials are harder).  However it is brittle, and hence not very tough.  In normal parlance, hardness and toughness are usually-conflated, but they are actually contradictory properties (which is why composites make the best armors).  This mistake is made in much modern science fiction, let alone that of the Interwar Era.

(5) - That's right, she's the Scientist's Beautiful Daughter.  Nobody claimed this story wasn't traditional.

(6) - "Astro-lithology" is an old term for what we now call "meteorics," or the geology of meteors and meteorites.

(7) - Two quick assumptions here.  The first, that over the next sixteen years people would keep building higher and higher buildings, and the second that not only would private airplanes become common but STOL ones capable of being flown off the roofs of skyscrapers.

The first was aborted by the Great Depression, World War II and the development of suburbia.  At the start of 1931 the tallest building in both New York City and the world was the Chrysler Building (1046 feet high, 77 above-ground floors).  The Empire State Building (1454 feet high, 102 above-ground floors) was already under construction, and would be finished on the spring of that same year.  However, the poverty of the Depression followed by the need to fight World War II and then the Korean War stopped further development of very tall buildings.  After WWII and Korea the universal availability of automobiles and growth of suburbia limited the demand for central-city floorspace, slowing the construction of the tallest skyscrapers.  In any case, the Empire State Building was very near the limitations of the architecture and materials science of the mid-20th century.

The assumption that small private STOL planes, or aircars, would become widely available and operated from the roofs of downtown skyscrapers was understandable in 1931.  Considering how far airplanes had progressed in the last 16 years -- from 1915 -- to 1931, it seemed reasonable that they would progress equally-far in the next 16 years -- to 1947.

And they did.  Mostly in the directions of greater engine power, resulting in bigger and faster airplanes with longer ranges and higher ceilings.  However, the avionics of the 1930's and 1940's never got to the point where it would have been safe for most people to operate them right over urban cores.  Nor do we see anything in the design of Jim's plane to explain why this should be possible.

The limitation of avionics technologies was the main reason why private airplanes never became as widely owned as private automobiles.  We are just now developing control systems sufficiently intelligent to allow safe operation by ordinary drivers.  Underestimation of the safety hazards of mass aircraft operation was the main mistake science fiction made with regard to the spread of airplane ownership, and it is the reason why improved avionics will be key to the eventual development of aircars.

(8) - It was not until I got to this point that I realized the informal version of the hero's name.  That Jimmy Carter was around 6-7 years old in 1931, and in our time line was a junior US naval officer in 1947.

(9) - Oh, simply "a matter of altering the valence?"  Do tell.

Actually, what one has to alter is the nuclear strucutre of the atom, which  may or may not incidentally alter the valence of the atom as a side effect.  Rich is here confusing nuclear with chemical processes, which is maybe forgivable because at this point in history the nuclear atomic model was still new to physics, and not all of its implications had yet been worked out.

(10) - Nature actually "accomplishes this alchemy" by means of bombardment of the nucleus with neutrons or gamma rays.  While it is true that sufficiently "great heat" would also do the trick (because it would produce light in the form of gamma rays and shake apart atomic nuclei), the heat required would be more on the order of the heart of a good-sized star, and to do it on a really large scale would require something more like a detonating supernova.  But again, this wasn't well-understood in the early 1930's.

(11) - Nope.  That only produces heat of at most a few thousand degrees Centigrade on any large scale:  we'd need many millions (and preferably billions) of degrees Centrigrade to do what the Professor wants.  If a meteor managed to do this one would notice it not so much as a meteor but as a rather large nuclear explosion in the upper atmosphere, producing damage to the ground below which would dwarf that of the Tunguska Event of 1908.

Nice try, though.

(12) - I know what's really going on here, but the obvious hypothesis for the Professor to form, based on the evidence so far would be some sort of non-biological chemical reaction.

(13) - Actually, the interior of a meteor can be quite cool.  This is because the meteor quickly slows to a terminal velocity of a few hundred miles an hour in the Earth's atmosphere:  there isn't time for the intense heat of atmospheric friction to be conducted from the leading edge, most of which melts or vaporizes and carries away that heat as it ablates.

H. P. Lovecraft handled the science much better in his similar story, "The Colour Out of Space" (1927).  But then, Lovecraft was an amateur astronomer.

(14) - We now know that comets are leftovers from the formation of solar systems.  In 1931, however, the dominant theory of solar system formation was the tidal model of James Jeans (stars pulled matter out of each other on close approaches which cooled to become planets) rather than the nebular hypothesis.

One possibility that the Professor is missing is that life might have evolved on cometary surfaces in deep space.  But in 1931 the notion of life independent of planetary (or at least lunar) surfaces would have been a very radical idea.

(15) - Given the assumed ability to survive temperatures that would reduce matter not merely to plasma but begin inducing actual nuclear changes in that plasma, having a metabolism whose waste heat is sufficient to melt or vaporize steel  is not implausible for the Comet Spawn.  The irony is that, in fact, comets are normally among the coldest naturally occurring objects in normal space in our Universe.  But then perhaps the Comet Spawn are dormant at very low temperatures, and quickened to life by high ones?  There are things almost as strange in actual Nature, though not (as far as we know) anything living in such a fashion.

(16) - I'm assuming that the eggs were relatively few and were gathered in major cities.  If they were, instead, distributed in very large numbers over the whole Earth, we'd be looking at a Mass Extinction Event here.  As it is, what Rich is describing would cause human death tolls in the tens of millions and the near-complete destruction of many major cities.  Such (literal) Inferred Holocausts were not uncommon in Interwar Era science fiction:  strangely, the authors often missed just how widespread they would really have been.  One thing that changed after World War II was that science fiction got a lot more explicit about such devastations, in part because the writers were well aware from the war itself what happens when one sets whole cities ablaze.

(17) - Rich has no excuse for his optimism here, as 1931 was just a quarter-century after the Great San Francisco Earthquake of 1906 (over a thousand dead) and less than a decade after the Great Kanto Earthquake of 1923 (over a hundred thousand dead), so he really should have known about firestorms and what one can do to an urban area.

(18) - And yet the Comet Spawn oddly failed to spark massive grass fires in these regions.  How convenient for the Earth!

(19) - Interview the Comet Spawn?  Are both Jim and his boss utterly insane?  (Though admittedly, they'd make hot copy.  *Rimshot*).

(20) - Oh, you mean did the engines overheat?  Yes, possibly.  Though my mind boggles at the thought of a whole squadron of US Army Air Force photo-reconnaissance planes all flying too close to the Comet Spawn and crashing due to engine failure, instead of trying to close the distance gingerly, one element or flight at a time.

Then again, equally dumb things have occasionally happened in the history of human aviation, as witness the fate of Flight 19 in December 1945, who all apparently got lost and kept on flying until they ran out of fuel and crashed either out at sea or in the Everglades (depending on which bearing one assumes they were on at the time).  Not one of the proudest moments for US Naval aviation!

(21) - And then there's that.  It's quite possible that the recon planes were actively intercepted.

(22) - It would require some awesomely parallel evolution for them to look much like our social insects, given that they obviously aren't even carbon-based water-soluble life forms -- but sure, why not?  And it's a terrifying visual image!

(23) - Of course, were these Earthly ants, their molting of their wings would indicate that they had now mated.  Which would have positively horrifying implications.

(24) - If the "Fire Ants" are that radiocative, at hundreds of feet distance, then Jim would probably have absorbed a fatal dose and by now be seriously ill.  Again, the mechanics of this were not well known in the days before anyone had actually split the atom.

(25) - It surprised me to discover that something at least roughly like this technique actually works.  Apparently the uranium ferrocyanide is insufficiently radioactive to itself interfere with the development process.  Though this does not sound like a very safe developing process, considering the toxic nature of the substances in question.

(26) - No.  Just no.  That's not how photography works.  Or the physics of light, really ("actnic rays" are simply ultraviolet light).  Not unless Jim and the Professor accidentally charged and released a laser capacitor, which I do not think is what's happening here.  Rich is conflating nuclear, chemical and optical processes here in a matter smacking more of alchemy and the Laws of Similarity and Contagion than any science I ever learned

(27) - We're again talking about millions of dead here, especially given that the "Fire Ants" are advancing "rapidly" (meaning that a lot of people can't get away in time) and the difficulty of feeding tens of millions of displaced persons.  This problem was not very well understood before World War II  and the Allied liberation of Europe, which led to millions of displaced persons -- many tens of thousands of whom died soon after liberation, owing to the problems of supply.

(28) - Why?  The Comet Spawn which fell into the sea were unable to hatch, and many small islands should have received no eggs at all!  Unless there were many, many billions of eggs falling on the Earth -- in which case, humanity should be almost extinct by now and the ecosystem going through a second Permian-Triassic scale mass extinction event.

(29) - Said chemical decomposition, however, would do nothing to neutralize the intense radioactivity of the new element.  Which implies that the world's oceans would now be contaminated by radiation.  On the other hand, given the sheer volume of the oceans, and the threat to the land posed by the living Comet Spawn, this is the least of their problems.

(30) - "Beta rays" are high-speed electrons or positrons.   They do not travel at the speed of light (since they possess mass), although they can travel at very fast sublight speeds.  "Alpha rays" are helium nuclei.  You cannot drag them out of atomic nuclei by the process the professor is using:  I think Rich has confused them with gamma rays.  There is also the obvious problem that large-scale nuclear processes require far more energy than the Professor likely has with which to work.

This is probably a good thing, as if the "sinister lump of metal" massed (say) a gram, the Professor would have just done the equivalent of detonating a 20-kiloton atomic bomb right in his laboratory.  This would, among other things, probably increase his insurance rates.  The detonation of a 20-kiloton atomic bomb in our time line in the city of Hiroshima definitely caused a major clean-up problem.

(31) - Oh, who can really keep track of the "byproducts?"  The likely "byproduct" of what the Professor did, as I repeat, would have been the vaporization of the laboratory and everything else for a block or two surrounding it, the leveling of the neighborhood it had occupied, severe damage to a large part of the city, and light damage to the rest of the city.  And a really pretty mushroom cloud.

But such things never happen accidentally to the Heroic Scientist in pulp science-fiction!

(32) - The Professor is ignoring the existence of a vast spheroid of iron, nickel and silicon which would stop the beta rays save in a direct line of sight from his device.  This vast spheroid is called "Earth."  Real beta rays can be stopped by a few millimeters of aluminum or a few centimeters of rock, let alone by whole terrestrial planets.

He's also ignoring the square-cube law, which would cause his spherical particle accelerator to be wildy-ineffective beyond point-blank range.  Just what insane amount of power is he pumping into that thing anyway?

If "beta rays" make the Comet Spawn disintegrate, and they are that sensitive to the effect that a little power goes a long way, why isn't sunlight achieving this effect?  The Earth's magnetic field screens off most of the solar wind, but not all of it, and the sun certainly has plenty of power!

And if it really made the Comet Spawn atomically-disintegrate, then he would have just set off millions, maybe billions of Hiroshima-sized atomic bombs distributed randomly over the Earth's surface.  I'm guessing that this would do some pretty severe damage to our ecosphere.

(33) - Why is it "suicide?"  So far, the Professor hasn't given us any reason to assume that using the beta ray is particularly dangerous. This looks like a ritual invocation for the sake of establishing Jim's heroism and building toward a dramatic climax.

(34) - Jan gets points for spunkiness, loses points for fundamental lack of logic.  It's weird that Jim didn't notice the extra load in what is a fairly small aircraft.  I also notice that she's apparently motivated only
 by concern for her beloved, seeming fairly-indifferent to her father's fate.

(35) - Wait -- our heroes are doing this from the ground?  Why, when one would imagine the area of coverage would be higher aloft, and a flying aircraft could maneuver against the foe?

(36) - Oh.  So that's why it's "suicide."  Too bad the Professor didn't have a few millimeters of aluminum with which to make a gunshield.  You'd think the idea would have occurred to him, especially if he was planning on operating the weapon.  Again, this feels contrived.

(37) - Indeed, if he's glowing he is indeed "highly radio-active."

(38) - Why not?  "Beta rays" aren't some utterly unknown emanation, and weren't in 1931 either:  they were discovered in 1900, thirty years before the story was written.  I don't know whether or not it was fully-understood that they were high-energy electrons, but it was most definitely understood how to shield against them, and such shielding was and is part of every X-ray machine ever built (otherwise, the machine would over-expose its own film)!  This is complete technobabble, put in the story for no better reason than to kill the Professor.

Which is stupid of the Professor, since as the inventor of the Comet Spawn killing beta ray blaster, he's one of the most important people alive.  Or was, until he committed Death by Own Design Stupidity.

COMMENTS:  'Spawn of the Comet' Compared With 'Spawn of the Stars'

Introduction:

This is a pure alien invasion story, which invites comparison with the other pure alien invasion story, written one year earlier, which I've previously run on this site, Charles Willard Diffin's "Spawn of the Stars" (1930) which I have previously run and reviewed on Fantastic Worlds.

Comparison:

One obvious difference between the two tales is that "Spawn of the Stars" is a military story in which Mankind fights a war against sapient aliens who attack with a flight of spacecraft, while "Spawn of the Coment" is a monster story in which Mankind is threatened with extermination by apparently non-sapient alien creatures whose eggs are scattered by a passing comet.  In "Spawn of the Stars," the aliens conduct a bombardment with weapons of mass destruction to annihilate the human military and production capabilities, presumably as advance raiders for some later effort, and the humans conduct air defense operations (not entirely without success) to attrition this raiding force.  In "Spawn of the Comet," the aliens cause damage to Mankind and threaten to destroy Earth's ecosystem as a simple byproduct of a biology which seems based upon radioactive hot plasma:  they swarm like social insects, building hives and issuing forth to swarm against humanity, and Earth's military forces can do nothing to even check their advance.

There are also obvious similarities between the two tales.  Both stories feature a protagonist who owns his own airplane and uses it to scout out the invaders.  Both stories have a scientist who builds an energy weapon which exploits the weaknesses of the aliens.  And in both stories the weapon is ultimately used to defeat the enemy, at the cost of the Heroic Sacrifice of at least one major character, including the scientist who invented that weapon (in "Spawn of the Stars" the scientist and the hero's best friend both die, while in "Spawn of the Comet" the scientist dies but the hero and his beloved both survive).

One difference is that "Spawn of the Stars" is a much deeper, more mature and more realistic tale.  Cyrus Thurston and his best friend "Slim" Riley are both delineated characters, and even Dr. Mac Gregor comes off as believable; while in "Spawn of the Comet" Jim Carter, Professor Stephen Wentworth and his daughter June Wentworth are very one-dimensional.  I can believe in Thurston and Riley's strong friendship far more easily than I can Jim and June's love.  Thurston and Riley are two eccentric individuals who have come to deeply like and respect each other; Jim and June are merely ciphers playing the roles of The Hero and the Love Interest.

What's more, Thurston and his friends are not fighting the threat alone:  they are doing so in cooperation with the United States and its military; in contrast, any organized human resistance in "Spawn of the Comet" is kept very much in the background.  This greatly enhances the verisimilitude of "Spawn of the Stars," and degrades that of "Spawn of the Comet."

The solution in "Spawn of the Stars" is much less easily achieved or applied than the similar solution in "Spawn of the Comet."  Dr. Mac Gregor has to investigate a downed Spawn ship and figure out their biology and technology before he devises the actnic ray; testing the weapon costs him his life; and then the weapon has to be installed with difficulty on a fighter plane, with little weight margin for shielding the pilot, and employed against the foe in difficult aerial maneuvers which ultimately cost Riley his life.  When the story's over, Man has defeated this invasion and gained a weapon generally-useful against that alien race -- but not necessarily defeated all future threats of invasion from that source.

By contrast, Professor Wentworth merely obtains (through highly-dubious chemistry) a sample of the alien metal and then with ridiculous ease develops a whole new technology of atomic disintegration with beta rays whose power source is never explained and builds his beta gun.  He then instantly mounts it on an airplane, not taking the trouble to even try to shield it (even though if it works like real beta rays this shouldn't be too difficult) and quickly employs it to wipe out an alien hive, dying in the process because of his own insanely-reckless folly in failing to shield himself against back-scatter.  The weapon is so absurdly effective that there is now no danger of the invaders winning.

Both stories employ dubious physics.  However, Diffin picks his main speculative-science premise (the supercompressed hydrogen, which serves the aliens both as power source and main weapon both for air combat and bombardment purposes) and thoroughly-explores its implications (the Spawn skyships can remain aloft for days and devastate whole cities with single attacks, but this means their bombs can be remotely detonated by the actnic ray).   Diffin is consistent in this analysis.

In contrast, Rich doesn't play fair with his speculations.  The aliens are hot plasmoid life based off a strange radioactive element.  Wentworth invents a beta ray gun which can (purely by auctorial fiat) disintegrate this element and do so without causing massive atomic explosions (avoiding doing so also purely by auctorial fiat).  In fact the beta beam is so effective that a single airplane equipped with one such device can slaughter a whole hive of the Spawn.

This is a Deus Ex Machina solution, and it's not even a consistently-applied one.  The obvious problem with turning the "Fire Ants" to energy is that it should result in lots of damage to everything around them, but this problem neither materializes nor does Wentworth even venture a guess as to why it fails to happen.

It is the same with the heroic sacrifices.  "Slim" Riley dies from the logical limitations of the actnic ray as an anti-skyship weapon, including the massiveness of the projector; Professor Wentworth dies because he couldn't be bothered to take the time to add any shielding (he says the situation is too critical and there is no time, but it is obvious that he is the most valuable man alive at that moment for the purpose of fighting the "Fire Ants," so what he does is not so much heroic as rash).  Wentworth's death is simply the application of Diablos Ex Machina to create a Bittersweet Ending..

Both are fun to read, but "Spawn of the Stars" seems very much more to be an alien invasion the way it might have happened in the early 1930's; "Spawn of the Comet" reads very much like a "me and my friends against the monsters" adolescent fantasy.

Conclusion

"Spawn of the Comet" is an enjoyable read, which introduces a deadly peril to Mankind and has The Hero discover it, The Science Hero defeat it, and the Hero and Love Interest affirm their love in the wake of victory.  However there is no depth to the story, no examination of the scientific speculations, and nothing to say from it about human nature, the nature of warfare, or (really) Man's place in the Universe.

Nothing but light pulp science-fiction.  Which is not necessarily bad.  Just limited.

END.

Retro Review: "Spawn of the Stars" (Charles Willard Diffin, 1930)

Introduction:

This is an alien invasion story, and an especially pure example of the genre.  Much of the science is dated, but the style is clear and the plot enjoyable.  Of additional interest, "Spawn of the Stars" appears to be a particularly seminal story, from which several alien invasion tropes famous from the movies of the 1950's and afterward, and even some which have entered the popular culture, seem to have originated.

Overview:

Viewpoint:  Third person, limited to Cyrus Thurston.  The only exception is that we hear of some scenes in montage, but they are very obviously being described by Thurston based on news he is getting from others.  We do not know anything that Thurston did not know himself.  This works well because Thurston is at some of the key points of the war, and is well enough educated that he understands a lot both of the military and of the engineering matters.

Style:  Direct, smooth and rapid, relatively unadorned with adjectives.  The only exception is in some of the descriptions of the aliens themselves, where detailed description is necessary in order both to convey information and mood.  This was not uncommon in the pulps, which were influenced both by Hemingway and by an overall journalistic technique.  Diffin was a clear communicator and a skilled writer, and the style helps carry rather than impending the tale.

Setting:  A contemporary or near-future Earth, c. 1930.  The aliens invade the entire world but we are limited to the main character's POV, and hence only see them attack parts of the United States of America, especially New York City and various West Coast cities.  Some detail is given of battles over Germany (Berlin is wiped out) and of alien activity over China.

Theme:  We live in a dangerous Universe, and the Spawn of the Stars may at any time descend and attack us:  fortunately, through courage and intellect, Man may triumph.  This is a common theme in alien invasion stories, and it is handled well here through use of characters to personify them:  Thurston is the viewpoint with whom we identify; Riley is raw Courage; MacGregor cool Intellect.  This is a "Power Trio", similar in structure to that of Kirk, McCoy and Spock from Star Trek: TOS.

Characters:

Cyrus R. ThurstonA young man, presumably in his 20's.  He's a "millionaire sportsman," which means that he's a rich man who decides to excel in sports, not that he has become a millionaire through playing sports.  He appears to be too young to have served in the Great War,  Cyrus is an air enthusiast and owns and operates at least one private airplane.  Cyrus is well-educated, socially-prominent, brave and passionate.

"Slim" Riley:   Thornton's pilot, a veteran of air combat in the Great War, and thus presumably in his 30's.  Slim is "Irish" (which in context probably means "Irish-American"), brave, intelligent, highly-skilled and a bit fatalistic (in part due to seeing so many of his comrades fall in the Great War).  Though Slim is technically Thurston's employee, the two are clearly good friends.  His heroic sacrifice wins the war for Mankind.

The Secretary of War:  Never named, if the story takes place in 1930 then he would be Patrick Jay Hurley, President Herbert Hoover's second Secretary of War, a proud, honorable and well-educated man who served in the Great War and was a diplomat and mining magnate in peacetime.  However, Diffin probably wrote the story in 1929, and hence he might have been thinking of James William Good, President Hoover's first Secretary of War, who died suddenly of a ruptured appendix on November 18th, 1929.

The Secretary of War shown in the story is a brave, active man who is at first willing to believe that the aliens may be friendly:  an enlightened opinion for 1930.  When he finds out that the aliens are hostile, he is willing to hazard his own life to scout out the situation.  This description fits Hurley better than it does Good.  Hurley would have been only 47 at the time of the alien attack, and thus physically able to participate in the adventure.  He is slightly injured in the Battle of San Diego, but survives the story.

General LozierAn intelligent and forward-thinking military officer, knowledgable in scientific and engineering matters.  He leads the fact-finding mission to and gets caught up and killed in the Battle of San Diego -- unfortunately, since he was clearly a very competent leader.

Doctor Mac GregorA brilliant and fearless scientist from the US Bureau of Standards.  He is sent to San Diego, observes the alien attack, and leads the recovery of the wrecked alien flyer.  Dr. Mac Gregor figures out how the alien engines and bombs work, discovers their key vulnerability, and develops it into a weapon.  He dies testing out his weapon on an alien bomb.

President Not Appearing in this Story:  Interestingly, one person we do not see in this story is the President of the United States of America, who in this period would be Herbert Hoover.  Historically, Hoover was a dynamic, progressive leader with a background in engineering, whose misfortune it was to be overwhelmed by a Depression of unprecedented magnitude, and it is improbable that he would have sat supinely and merely watched a crisis of this magnitude.  His absence in the story is probably due to the trope of the Invisible President, which was if anything much stronger in the 1920's and early 1930's than it is today:  in part because, before FDR's Fireside Chats, most people did not get to hear the President speak on anything like a regular basis.  We may logically assume that much of what was happening above Cyrus Thurston's level of involvement was being coordinated by President Hoover.

Plot:  Millionaire sportsman Cyrus R. Thurston is flying west across the United States on a whim, with his pilot and friend Slim Riley.  They are forced down by engine trouble (which may or may not be a coincidence, though the aliens at no other point demonstrate the ability to cause engines to misfire) and happen to land near an alien spaceship (1).  They see an alien on the ground.  The alien ship takes off, and they discover a cow which the alien has partially consumed (2).

Reaching Los Angeles, they are sitting in their hotel room wondering whether what they saw was real or a mere nightmare, when they read the newspapers and discover that the skyspheres have been sighted all over the world.  Now certain that what he saw was real, Thurston decides to go to the government with his eyewitness experience of the aliens.

Thurston and Riley fly to Washington, DC, where Thurston's social prominence gets him an interview with the Secretary of War.  The Secretary believes Thurston, and asks Thurston and Riley to accompany him and General Lozier and MacGregor, a scientist from the Bureau of Standards, to the West Coast, where the ships have just destroyed Vancouver in a series of  tremendous fiery explosions from their main drives, and are working their way southward.  The men fly west.

The Spawn scout out Seattle and San Francisco, but do not attack again as our heroes race west and US forces get into position to bring them to battle.  The aliens and the Secretary's party reach San Diego around the same time.  The Spawn destroy San Diego with a single tiny bomb that yields a kilotons-range explosion, and the battle is on.

The Secretary's plane is badly damaged in that tremendous explosion:  General Lozier and the Government pilot are slain.  Slim Riley lands the cripple as US forces go into action.  The US Army Air Force, reinforced by two US Navy aircraft carriers, and supported by anti-aircraft artillery, launches an attack.

The American attack is wholly ineffectual.  The alien weapons smash the carriers to burning hulks, swat the airplanes out of the sky.  The anti-aircraft guns appear unable to hit the fast, agile alien flyers.  At the end of the day San Diego lies in ruins and American airpower has been greatly reduced.

That night our heroes are resting in a ruined building when the word comes:  one of the five skyspheres is coming back!  They wait in fear and then spot the thing -- but its flight is clumsy. It's been badly damaged.  They follow the flyer in a car as it crash-lands nearby! (3)

Piling out, they see the monstrous alien pilot ooze from the ship.  Thurston, moved by wrath at the murder of San Diego and xenophobic hatred of the inhuman Spawn, attacks it with a handgun -- to no avail, as the amorphous alien is not harmed by the small slugs.  Dr. MacGregor realizes that the alien may be vulnerable to light, and drives it back with a flashlight.  Before the alien can get back to its sphere, the sun rises, destroying the monster.

Thurston and MacGregor investigate the crashed skysphere and discover that the Spawn technology seems to be based on ultra-compressed hydrogen and its chemical reactions.  They manage to salvage one of the bombs, and scientists investigate the wrecked skysphere.

The Spawn, in their four remaining skyspheres, strike Germany and destroy Berlin.  They are now massing against New York.  Slim Riley recovers from the wounds he suffered in the air crash, and Dr. MacGregor develops a ray which he believes will be able to penetrate the skysphere hulls and slay the Spawn by means of the same vulnerability they showed to sunlight.  Unfortunately, the scatter of (gamma?) rays from the projector will doom any human using the ray to a slow and horrible death (presumably either by radiation sickness or cancer). (4)

MacGregor tests his ray to see if it will detonate an alien bomb.  Unfortunately he miscalculates and is smothered in the sudden release of hydrogen (5).  Fortunately, he leaves his notes and plans for building a MacGregor Ray projector, and the US Army rapidly installs such a projector on a fighter plane.  Slim Riley, torn by survivor's guilt over both the Great War and San Diego, volunteers to fly it, despite the likelihood of a horrible death from the radiation.

The Spawn attack New York City.  Their bombs begin blasting the great metropolis, as Slim Riley rises to meet it in his ray-armed fighter.  The aliens at first do not realize the threat, until Riley launches his attack, in swift succession irradiating three of the four skyspheres.  The last one, now alerted to the peril, tries to escape, but Riley attacks it from below, hitting its bombs with the death ray (6).  Riley and the last skysphere are both destroyed in the resultant colossal explosion

On the ground, Thurston sobs in mingled relief and sorrow.  He, the city, and the Earth have been saved, but at the cost of the life of his friend.  But at least, as Thurston realizes, Riley died well:

Cyrus Thurston, millionaire sportsman, sank slowly, numbly to the roof of the Equitable Building that still stood. And New York was still there ... and the whole world....

He sobbed weakly, brokenly. Through his dazed brain flashed a sudden, mind-saving thought. He laughed foolishly through his sobs.

"And you said he'd die horribly, Mac, a horrible death." His head dropped upon his arms, unconscious—and safe—with the rest of humanity.


ending the tale.

Analysis:

The Aliens:  These are amorphous horrors,

Its blinding whiteness made the more loathsome the sickening yellow of the flabby flowing thing that writhed frantically in the glare. It was formless, shapeless, a heaving mound of nauseous matter. Yet even in its agonized writhing distortions they sensed the beating pulsations that marked it a living thing.

There were unending ripplings crossing and recrossing through the convolutions. To Thurston there was suddenly a sickening likeness: the thing was a brain from a gigantic skull—it was naked—was suffering....

The thing poured itself across the sand. Before the staring gaze of the speechless men an excrescence appeared—a thick bulb on the mass—that protruded itself into a tentacle. At the end there grew instantly a hooked hand. It reached for the black opening in the great shell, found it, and the whole loathsome shapelessness poured itself up and through the hole.


Only at the last was it still. In the dark opening the last slippery mass held quiet for endless seconds. It formed, as they watched, to a head—frightful—menacing. Eyes appeared in the head; eyes flat and round and black save for a cross slit in each; eyes that stared horribly and unchangingly into theirs. Below them a gaping mouth opened and closed.... The head melted—was gone....

with the power, as detailed above, to form and reabsorb temporary organs.  The similarity to one of H. P. Lovecraft's shoggoths is clear, and indeed so clear that I immediately wondered if Lovecraft got the idea for his shoggoths from Diffin's invaders.

As most of you probably know, the first detailed description of a shoggoth comes from Lovecraft's novella At the Mountains of Madness, written in 1930-31 and published in 1936.  In other words, written right after Diffin's story was published, at a time when Lovecraft, a voracious reader, would still have had the tale fresh in his mind.  However, shoggoths were also mentioned in "Night-Gaunts," sonnnet XX from Lovecraft's  Fungi from Yuggoth, written 1929-30 and published as individual sonnets in various fantastic fiction magazines, especially Weird Tales.  They were not, however, described in detail in the poem, and I now believe that Lovecraft may have been inspired by Diffin's creation.

Of course, the concept of an amorphous horror ultimately derives from a unicellular protozoan animal, the amoeba, which famously feeds by forming temporary "arms" (pseudopods) "mouth" and "stomach" (vacuole) to grab, engulf and digest its tiny prey.  However, amoebae do not form complex temporary organs, nor are they particularly intelligent.  The concept of a race of sapient giant amoeboids seems to derive from Lovecraft by way of Diffin, with Diffin's aliens coming chronologically first, but Lovecraft's being far more influential due to the greater popularity of At the Mountains of Madness.

E. E. "Doc" Smith's Eddorians can basically be described as super-intelligent, super-scientific and super-psionic shoggoths:  they are truly nightmarish creatures, and their first appearance in the original version of the "Lensman" series was in 1947, which was a decade after the publication of At the Mountains of Madness.  Smith probably had them in mind from the beginning of his series, however, the first part (Galactic Patrol) of which was published in 1937-1938 (7).

We never really learn all that much about the Spawn of the Stars.  We know that they are bigger and stronger than humans; they may also be smarter, or at least better at multi-tasking, because the invasion consists of five ships, each operated by one alien -- in other words, the whole human race is being attacked by the equivalent of a single flight of aircraft.  This is, and is meant to be, humbling.  One of the points of the story is the importance of superior technology in warfare, and the superior technology of the aliens allows a mere five of them to level Mankind's cities and swat our air forces out of the skies with terrible ease.

The aliens definitely have a more flexible biology than ours:  their natural atmosphere appears to be hydrogen-rich, yet they breathe ours without difficulty, and the fact that they eat Earthly cattle implies that their basic biology is not that dissimilar to our own (8).  Their brains appear to be dispersed through their whole bodies, and they can form and reabsorb their temporary organs with considerable speed.  Despite their size, they can move rapidly.  They have one great weakness:  strong light, in the optical and higher frequencies, rapidly disrupts their life processes and decomposes their tissues:  even a flashlight is "like the touch of hot iron to human flesh," a Very flare causes them to flee in terror, and, as for direct sunlight:

Incredible in the concealment of night, the vast protoplasmic pod was doubly so in the glare of day. But it was there before them, not a hundred feet distant. And it boiled in vast tortured convulsions. The clean sunshine struck it, and the mass heaved itself into the air in a nauseous eruption, then fell limply to the earth.

The yellow membrane turned paler. Once more the staring black eyes formed to turn hopelessly toward the sheltering globe. Then the bulk flattened out on the sand. It was a jellylike mound, through which trembled endless quivering palpitations.

The sun struck hot, and before the eyes of the watching, speechless men was a sickening, horrible sight—a festering mass of corruption.

The sickening yellow was liquid. It seethed and bubbled with liberated gases; it decomposed to purplish fluid streams. A breath of wind blew in their direction. The stench from the hideous pool was overpowering, unbearable. Their heads swam in the evil breath....


Armed with this evidence, plus the fact that their energy and explosives technology seems to be based on a supercompressed form of metallic hydrogen, it seems obvious from an early 21st-century point of view that the Spawn originate from the atmosphere of a large gas giant, such as Jupiter or Saturn.  They evolved below the visible cloud cover and above the metallic hydrogen ocean:  at home they would probably spread out into vast balloon or airfoil shape ("puffed shoggoths" indeed) and float or fly through their skies, forming temporary tentacles to secure prey.

It's a beautiful concept, and part of the beauty of this concept is that, though it makes perfect sense, it wouldn't have occurred to Diffin.  He wasn't stupid or ignorant -- it's just that in the 1920's, astronomers (there were as yet no "planetologists") assumed that the gas giants were pretty much terrestrial planets writ large, complete with abrupt transititons between "air" and "land," and with "oceans" properly confined to "seabeds," thank you very much.  Our current view of their atmospheres as slowly thickening into metallic-hydrogen slush and then hydrospheres, which in turn slowly thicken into increasingly-silaceous "mud" and then lithospheres, would astonish them.  But it is perfectly consistent with the physical nature of the Spawn as shown in the story.

We know absolutely nothing about the aliens' culture or motives for attacking Mankind, which is what makes this such a "pure" alien invasion story:  there are aliens, and they invade the Earth, period.  Thurston considers them evil, but then as a human under unprovoked attack, this is reasonable.  What's less reasonable is that he considers them evil the moment he sees them, based apparently on the alienness of their shape alone, before they've done anything hostile, to his knowledge, beyond eating cattle.  This could be marked down to third-person limited narration (all we see of the story world is what Thurston sees, all the opinions we get are what he either thinks or hears), except that Diffin obviously means Thurston's opinion of the aliens to be perfectly reasonable, and of course Thurston is right:  the aliens attack humanity without any discernable provocation or claim of need.

What one needs to remember was that, in the world of 1930, this sort of shape-based xenophobia was assumed to be normal, rational and sane.  Part of the reason was that the very concept of "alien life" was still new, and it was generally believed that most alien life (at least, alien life "like ourselves") would be very humanoid in shape.  This was more than just sentiment:  the evolutionary theory of the day imagined that the human form constituted something like perfection for a sapient being, so any very non-humanoid alien would have to be either "imperfect" or a very different kind of "sapience." 

One should add to this the assumption that different species would "necessarily" have to engage in a violent struggle for habitat:  the evolutionary biology of the 1920's barely acknowledged symbiosis or commensalism of any sort.  There were predators and prey, parasites and hosts, and that was pretty much that, especially in the popular-science variety of evolution.  So, if Spawn from the Stars suddenly appeared, it would logically follow that they wanted our habitat and, being super-scientific and hence unsentimental about such things (unlike we weak religious-morality-influenced men of the 20th century) would proceed to our extermination, forthwith.  This was also, note, the underlying concept of H. G. Wells' War of the Worlds.

This was about to change.  In none other than Lovecraft's At the Mountains of Madness (mentioned before), the hero was to feel sympathy for the (very) physically-alien Elder Things, even while retaining his horror at the Shoggoths.  Stanley G. Weinbaum would introduce us to friendly (though still semi-humanoid) aliens in "A Martian Odyssey" and "Valley of Dreams" (both 1934).  And most significantly, E. E. "Doc" Smith depicted a peaceful, multi-racial interstellar Civilization in his Lensman stories, starting with Galactic Patrol, some of whose members were very non-humanoid indeed (9).

Skyspheres and Other Possible Spawn Spacecraft

The alien technology includes metallurgy, which allows them to build large, light but strong spherical skyships, which may also be spaceships or at least landers (10):

It was of metal, some forty feet across, its framework a maze of latticed struts. The central part was clear. Here in a wide, shallow pan the monster had rested. Below this was tubing, intricate coils, massive, heavy and strong. 

There was a surprising simplicity, an absence of complicated mechanism.

If the aliens are Jovians or Saturnians (as seems very possible), then they may have launched a (well-shielded) interplanetary cruiser from Callisto or Titan, which carried the five sky-spheres as auxiliary craft, and went into a fairly close orbit of the Earth.  From this orbit the ship could launch and retrieve the sky-spheres without their occupants suffering undue radiation exposure.  Some of the odder maneuvers of the sky-spheres would be perfectly explicable if we assume that their own descents and ascents had to be coordinated with the orbit of their mother cruiser.  Within Earth's Van Allen Belt magnetosphere (whose existence unknown to Diffin in 1930), the skyspheres and mothership alike would both be protected from Solar flares.

This would explain why the crippled skysphere stayed behind at San Diego, and why none of the other skyspheres rescued its pilot.  The skysphere may have been damaged to a point where it was unable to launch into orbit and rendezvous with the mothership:  this may not have been discovered for certain until the whole flight of skyspheres attempted return to orbit.  Once the other skyspheres had launched, a return to Earth would have been impossible until the mothership fell into an appropriate position on her next orbit.  Before this could  be arranged, Cyrus Thornton and MacGregor killed the pilot and captured his sphere, and the aliens decided not to throw more of their limited assets into a fight over their ruined auxiliary vessel.  The reason why the skysphere did not attempt to fly far from San Diego may have been that its fuel was close to exhaustion, and also that too great a geographical displacement would have rendered a rescue more difficult, or even impossible.

Supercompressed Hydrogen Technology

The alien engines and bombs both employ an interesting chemical technology which appears to concentrate energy at a level midway between what we think of chemical and nuclear reactions.  Essentially, the Spawn have developed a means of compressing hydrogen to and beyond the point of what we would term its liquid metallic phase.  The supercompressed hydrogen can then be released in a controlled fashion, expanding into ordinary diatomic hydrogen molecules, either to do work directly through its gas pressure (as used in the skyspheres' drives) or to mix with oxygen in the Earth's atmosphere and then be detonated as a thermobaric explosive (such as the US uses today in its fuel-air bombs).

The generator, with its tremendous braces to carry its thrust to the framework itself, filled most of the space.

As a main drive, the system is demonstrably efficient enough to enable a Spawn skysphere to hover and maneuver in the Earth's 1G field for hours at a time:  this compares favorably with the likely performance of a nuclear fusion "torch" drive, and the skysphere can do this running the drive "cold" (without igniting the hydrogen plume).  It should also be considered that the Spawn probably used a variant of their skysphere engines to reach escape velocity from their gas giant homeworld, which might have been from 0.886 G (if Uranus) to 2.528 G (if Jupiter).

 Some of the ribs were thicker, he noticed. Solid metal, as if they might carry great weights. Resting upon them were ranged numbers of objects. They were like eggs, slender, and inches in length. On some were . They worked through the shells on long slender rods. Each was threaded finely—an adjustable arm engaged the thread. Thurston called excitedly to the other.

"Here they are," he said. "Look! Here are the shells. Here's what blew us up!"


He pointed to the slim shafts with their little propellerlike fans. "Adjustable, see? Unwind in their fall ... set 'em for any length of travel ... fires the charge in the air. That's how they wiped out our air fleet."

There were others without the propellors; they had fins to hold them nose downward. On each nose was a small rounded cap.

"Detonators of some sort," said MacGregor. "We've got to have one. We must get it out quick; the tide's coming in."


As a thermobaric weapon, the detonation from a device small enough for a human to clasp his hands around the fuselage is enough to destroy the downtown of a moderate-sized city:  multiple bombs can devastate an entire moderate-sized city including the near suburbs.  This implies a yield in the single-kilotons range, and an efficiency considerably greater than that of an atomic fission weapon, though inferior to that of a fission-fusion or fission-fusion-fission explosive.  A Spawn thermobaric bomb is much more physically massive than one would imagine at a glance (the supercompressed hydrogen is denser than osmium), but the whole apparatus is far smaller and less massive, than, say, were the Hiroshima or Nagasaki bombs.  The detonation of Spawn thermobaric bombs do not appear to produce radiation hazards:  the reaction is probably entirely chemical.

A side effect of both the skysphere drives and thermobaric bombs is the release of immense quantities of the supercompressed hydrogen, producing suffocation of entities (such as ourselves) unable to breathe the gas, and a freezing cold (due to the gas expansion taking up heat) equivalent to that of Earth's Arctic or Antarctic regions.  An interesting aspect of the supercompressed hydrogen is that it is initially far denser than air and thus falls rather than rises in Earth's atmosphere, until it has expanded sufficiently to become lighter than air (as is normal for diatomic hydrogen under Earthly conditions).  The result is the saturation of a large volume of Earthly atmosphere with the gas, and a very complete mixture with the oxygen, which is ideal both for suffocation and detonation purposes.

The aliens would be unable to contain the immense pressures needed to maintain the supercompressed hydrogen in that phase aganist the relative vacuum of either space or even Earth atmosphere at sea level, were it not that the supercompressed hydrogen is actually stable, and the design of the containment vessels destablizes it as it exits.  As MacGregor discovered:

"Hydrogen," the physicist was stating. "Hydrogen—there's our starting point. A generator, obviously, forming the gas—from what? They couldn't compress it! They couldn't carry it or make it, not the volume that they evolved. But they did it, they did it!"

Close to the coils a dim light was glowing. It was a pin-point of radiance in the half-darkness about them. The two men bent closer.

"See," directed MacGregor, "it strikes on this mirror—bright metal and parabolic. It disperses the light, doesn't concentrate it! Ah! Here is another, and another. This one is bent—broken. They are adjustable. Hm! Micrometer accuracy for reducing the light. The last one could reflect through this slot. It's light that does it, Thurston, it's light that does it!"

"Does what?" Thurston had followed the other's analysis of the diffusion process. "The light that would finally reach that slot would be hardly perceptible."

"It's the agent," said MacGregor, "the activator—the catalyst! What does it strike upon? I must know—I must!"


...

"What is it that explodes? Nobody knows. We have opened the shell, working in the absolute blackness of a room a hundred feet underground. We found in it a powder—two powders, to be exact.

"They are mixed. One is finely divided, the other rather granular. Their specific gravity is enormous, beyond anything known to physical science unless it would be the hypothetical neutron masses we think are in certain stars. But this is not matter as we know matter; it is something new.

"Our theory is this: the hydrogen atom has been split, resolved into components, not of electrons and the proton centers, but held at some halfway point of decomposition. Matter composed only of neutrons would be heavy beyond belief. This fits the theory in that respect. But the point is this: When these solids are formed—they are dense—they represent in a cubic centimeter possibly a cubic mile of hydrogen gas under normal pressure. That's a guess, but it will give you the idea.

"Not compressed, you understand, but all the elements present in other than elemental form for the reconstruction of the atom ... for a million billions of atoms.

"Then the light strikes it. These dense solids become instantly a gas—miles of it held in that small space.


"There you have it: the gas, the explosion, the entire absence of heat—which is to say, its terrific cold—when it expands."

MacGregor's explanation is partially nonsensical given what we know today, and there is no particular reason to belive the obseved effects possible given real-world science, but there is also no particular reason to believe it impossible -- we have never been able to experiment with hydrogen under the extreme conditions of pressure and temperature to be found within the hydrospheres, let alone lithospheres, of gas giants.  And there is an easy way that this could be possible -- photons of the right wavelength could knock loose electrons from atoms arranged in metallic lattice structure, causing it to break down.  Real-world photoelectricity (and photography) operates through a similar process, though with far less violent consequences.

Another obvious question is why, given so much hydrogen, and presumably understanding the laws of physics at least as well as did 20th-century humans, the Spawn do not use in the obvious manner as a nuclear fusion fuel or explosive.  I think that the answer is to be found in their extreme vulnerability to hard radiation.  A deuterium-tritium fusion reaction, which is the easiest controlled reaction to induce, produces free neutrons which are not only directly damaging, but also render the reactor vessel or its surroundings radioactive.  Even humans would need to shield a DT fusion reactor installed in any crewed craft; for the radiation-sensitive Spawn, the required shielding might be prohibitively massive.

I get the impression that the Spawn do not bother much with tools for ordinary mechanical or perhaps even electrical purposes, as they can simply form from their malleable bodies organs to serve as wrenches, screwdrivers, test probes and the like.  Likewise, their control systems are simple, since their own bodies can be control levers, knobs, dials and other readouts as required -- thus the "extraordinary simplicity" of their skyspheres. 

However, there is one obvious weakness to such a design philosophy -- it becomes very hard to handle anything that one's own body cannot endure.  They would thus would be particularly handicapped in any attempt to build nuclear devices of any sort, since waldoes would be difficult for a race not generally used to making manipulators.  And of course, their fear of any kind of nuclear accident would far exceed our own.

It's true that the deuterium-trihelium reaction (D + He3) produces no free neutrons, and the very limited electromagnetic radiation (mostly no worse than actnic) would be easy for even the Spawn to handle given the interposition of any sort of metal shield.  But the DHe3 reaction also runs ten times hotter than the DT, and it would be difficult to start a nuclear fusion power technology with trihelium if one had not first gained some experience with tritium-based reactions.  Given that the Spawn have a perfectly adequate drive and bomb technology with their supercompressed hydrogen, they have little incentive to invest in such a hazardous (to them) technological course as nuclear fusion.

Strategy

The Spawn were of course overconfident, which is what doomed their invasion to failure.  They correctly realized that their skyspheres were invulnerable to the (small-caliber) guns carried by Earthly aircraft c. 1930, and that they were too fast for human ground-based artillery to target.  They however failed to grasp the "golden BB" theory, which is that an aircraft may be downed even by poorly-aimed fire in sufficient volume:  this is what did for the first skysphere Thurston and MacGregor then salvaged, and it gave humanity enough information to devise a weapon designed specifically to shoot down skyspheres.

Stop and consider the way in which the aliens would have had to achieve victory, given the tools at hand.  Obviously, they were aiming to destroy the human military and industrial capabilities through strategic bombardment, using what amounted to five fighter-bombers armed with racks of tactical kiloton-range bombs.  This would have necessitated first systematic probes against the human defenses, to locate the centers of human communication, defense, population and production; followed by the systematic bombing of these centers.

There is no way, unless they received significant reinforcement, that they would have been able to wipe out the human population, or even enough of it to render ground operations anything but very hazardous.  They were clearly aware of their own vulnerabilities to light and harder radiation, else they could not have crossed the dangerous environs of the Inner System to operate on Earth.  They could have seen from orbit that we had the technology to generate a lot of light (one of their objectives was probably to knock out our urban electrical generation capabilities, but they can't have been unaware that given our mastery of electricity we almost certainly also had portable batteries).  So they must have known that oozing about, even at night, in full view of any organized human resistance was close to suicidal.

Obviously, therefore, the aliens would have needed to first damage our industrial plant and heavy military assets (ships, artillery and vehicle parks, etc.) enough so that we lost the capability to rapidly intervene on the ground against a landing, then have a follow-up ground attack force secure an area in terrain enabling easy defense of a space-head against human counterattack.  We don't know enough about the aliens to be certain of their space-head requirements, but their large size, high metabolisms and vulnerability to light suggests that they would want to capture an island -- one large enough for herds of animals to victual them, and small enough that all humanity there could be slain.  Once they had sunk our navies and major merchant shipping, counterattack against an island would have been difficult for us, and the aliens as described could have functioned perfectly well in Earth's oceans (which might not have been that different from their gas giant atmospheric home), swimming through darkness to intercept amphibious attacks, or raiding the shoreline by night.

The aliens could probably wear survival suits (given their anatomy, probably elastic bags) designed to protect them from sunlight, using the same material they built their ships' viewports from as goggle-lenses through which their large, probably infra-red or microwave-radar sensitive eyes could peer at the inconceivably radiation-rich and hellishly solid environment in which the monstrously rigid "human" vermin pranced about just as if it were the cool and flowing skies of Home!  They might have fought human soldiers with their own superior strength, or more likely with super-scientific weapons, such as flamers or explosive grenades based off the same compressed metallic-hydrogen technology on which their engines and bombs operated.  The pilots of the skyspheres in the stories did not have such devices, but then the skyspheres were supposed to have been impossible for the humans to shoot down.

Of course, when the humans developed the radiation beam cannon, this would no longer have been a practical strategy:  their skyspheres and ground forces would now be vulnerable, and on the end of a long logistics tether.  The aliens aborted their invasion, returning home to think, plot and plan their inevitable return, to win the resources of the metal-rich planet obviously wasted on the hideous human creatures.  When will they strike again?

The Humans

One must start by recognizing the ways in which c. 1930 Earth was more primitive and less capable of defending from itself attack, especially from the air, than would be the Earth of today.  There were no nuclear missiles, or for that matter nuclear weapons or significant rocket weapons of any kind.  There was neither radar nor proximity fuses, which meant that anti-aircraft fire was incredibly inaccurate by modern standards.  A defender would be unaware of an enemy air attack until the enemy craft had been visually sighted.

Airbases had not yet developed any but the most limited methods of controlling the squadrons they launched:  radios were clumsy and unreliable, and had only recently been applied to anything as small as fighters.  Air combat doctrine was in its infancy -- squadron-based tactics were had only been invented within the last 15 years, and combat aircraft within the last 20.  The idea of controlling squadrons across a whole theater of operations from a central command room (the British "Fighter Command" system of World War II) would not appear for a decade in Our Time Line.

Aircraft carriers were rare, small by modern standards, and the capabilities of carrier-launched aircraft limited.  In particular, they had operational radii of no more than a few dozen to few hundred miles.  They would be of use primarily in a fight for a port city, as was the case in the Batle of San Diego.  Naval forces had even by World War II standards only very limited abilities to protect themselves against enemy air attack, as was discovered in that battle when the Spawn easily smashed two American carriers (and presumably sunk their escorts).

Combat aircraft were single-engined open-cockpit biplanes, limited to altitudes of a few miles and speeds of a couple of hundred of miles an hour, maximum.  They massed at most several tons, and were armed with .30 to .50-caliber machine guns or small iron bombs.  Built primarily of fabric over wooden or metal struts, they were very fragile.  Their fuel tanks had no self-sealing features, neither cockpit nor engines any armor, and almost any sort of damage could easily bring them down.

Gunsights were simple fixed crosshairs. which meant that one could not reliably hit a maneuvering target (such as a Spawn skysphere) at more than a few hundred yards.  The limited power of the .30 to .50-caliber bullets was, in the story, insufficient to penetrate the metal hulls of the skyspheres.  Aircraft cannon were technically possible, and heavy  (37mm+) aircraft cannon might even have penetrated the Spawn skyspheres, but such weapons had not yet actually been deployed.

Bombs were dropped by guesswork, which meant that they were incredibly inaccurate against anything smaller than a city or major building complex unless dropped from an altitude of a few hundred yards while flying straight and slow.  The chance of hitting a Spawn skysphere in midair with a ground attack bomb would have been very low (tetherered observaton balloons were successfully attacked with such weapons in the Great War, but those did not maneuver).  Air-to-air missiles would not be invented for a decade and a half.

This goes a long way toward explaining the Earthly vulnerability to the Spawn attacks.  Even the Earth of 1940, let alone 1945 or 1950, would have been able to defeat a mere five skyspheres fairly quickly, if they attacked any seriously-defended site.  Neither the Earth of 1930 nor 1950 would have been able to detect or engage an orbiting Spawn mothership, though we could do it today with anti-satellite weapons.  (Whether or not we could overcome its defenses is debatable, since the story mentions no such motherships, and I simply surmise them from the small size and limited facilities of the skyspheres).

We do develop one weapon which proves effective against the aliens, however:

The MacGregor Ray

"In Washington a plane is being prepared. I have given instructions through hours of phoning. They are working night and day. It will contain a huge generator for producing my ray. Nothing new! Just the product of our knowledge of radiant energy up to date. But the man who flies that plane will die—horribly. No time to experiment with protection. The rays will destroy him, though he may live a month.

In 1900, Paul Villard discovered and in 1903, Ernest Rutherford named gamma rays, which are electromagnetic radiation with frequences greater than 10 exahertz.  The first cyclotron was built by Ernest Lawrence at UC-Berkeley in 1932, which makes it perfectly plausible that a brilliant engineer might be able to rush one to a field application c. 1930.

It's not clear exactly what the MacGregor ray is or how it is produced, but the story implies that it is a high-frequency electromagnetic ray capable of penetrating the metal of the Spawn skyspheres.  The description would fit anything from high-frequency X-rays up.  Furthermore, the horrible death likely to be suffered by the operator due to the lack of time to experiment with protection implies that the radiation is being produced by some form of radioisotopes, possibly under compression (an anticipation of the method actually used to induce nuclear fission both in reactors and in bombs).  The shielding problem would stem from the need to install the weapon on a combat aircraft capable of catching the skyspheres:  obviously, thick lead would work, but as obviously would not be practical on a c. 1930 fighter plane.

An actual gamma-ray laser ("graser") or even x-ray laser would be highly unlikely given the technological limitations of 1930 (today we can just barely and in theory make a nuclear explosion-pumped x-ray laser).  It's more likely that we're talking about a sort of gamma-ray "flashlight," a weapon whose radiation at range would be far too puny to be a practical death-ray against humans (even the pilot, sitting right next to the ray, would only suffer radiation poisoning leading to eventual death), but is sufficient to slay the radiation-sensitive Spawn.

In time, Earthly engineers would be able to lick the blowback problem which caused radiation poisoning to the operator.  But the Earth didn't have the time.  Future Spawn invasions, however, will have to contend with the presence of MacGregor ray cannons in the hands of human defenders.  Perhaps this will be enough to deter them.  Perhaps ...

Musings and Speculations:

Alien Invasions

"Spawn of the Stars" is an utterly pure alien invasion tale.  We never learn where the aliens were from or what they want (other than to kill us).  They show up, they start killing us, and we must kill them first if humanity is to survive.  This is both a product of the racialist philosophies of the age, and a major virtue of the story -- nothing gets in the way of the threat and the need to solve the problem through the intelligent application of physical force.

Compare with War of the Worlds, in which the human race never does find a weapon against the Martians:  we are saved by pure dumb luck and the virulent diseases of our mother planet.  Or with Footfall (Larry Niven and Jerry Pournelle, 1985), in its own way as much a classic of the alien invasion genre as WotW, in which humanity does launch a warship capable of defeating the invaders, but this proves possible as much due to the limitations of the Fithp imagination and personality as due to the pluck and wit of Mankind.

Both War of the Worlds and "Spawn of the Stars" are far more frightening than is Footfall, Turtledove's Worldwar, or other more recent alien invasion novels, and the reason is simple.  We get to see things from the viewpoint of the Fithp and the Race, and indeed to sympathize with them (to some extent) (11).  By contrast, Wells' Martians and Diffin's Spawn are mysterious, implacable, and superhuman forces of destruction.  Their motives and nature are unknown, and the unknown is always more terrifying than the known.

As mentioned, Thurston's extreme xenophobia at sight of the Spawn's amorphous anatomy, which extends to a conviction that they are evilly intelligent, seems to be justified in the light of their later behavior.  The assumption here, from what I could tell, was that the alien was to be presumed hostile, and the more so if it was hideous to human eyes.  This assumption is identical to that of the early Lovecraft, though not of the later Lovecraft, and especially not to that of the later E. E. "Doc" Smith, who had extremely nonhumanoid heroes such as Worsel, Tregonsee and Nadreck, in the Galactic Patrol.

At no point does Thurston become aware of any attempt by either side to communicate with the other, and the impression I got from the tale was that, if we tried, we were probably ignored.  The science of the day took the Darwinian "struggle for existence" quite literally, and the science fiction of the day depicted this struggle as being carried out with super-scientific weapons between sapiences of different forms.  The culmination of these beliefs was, of course, the carnage of World War II, and the deaths of tens of millions at the hands of the Nazis and Communists.

Today, we tend to make more peaceful assumptions about sapient alien:  influential in this regard has been the books of Carl Sagan, who argued that aliens adavanced enough to engage in interstellar travel would have either culturally evolved past wars of aggression, or destroyed themselves with weapons of mass destruction.  Others still believe differently, particularly Charles Pellegrino and George Zebrowski, who in The Killing Star (1995) argued that alien civilizations would be inclined to mutual destruction owing to the fear that other (alien and hence unpredictable) beings would enter aggressive cultural phases and the desire to destroy such civilizations, before they could strike.

The true state of affairs is still unknown.  It may be closer to Sagan's vision, it may be closer to Pellegrino's.  Reason would argue in favor of some caution when dealing with alien sapience, and especially in regard to more advanced alien civilizations.

Air-Mindedness and Scientific Research

One thing that strikes me about the story is that it is remarkably air-minded for a tale penned in 1929.  Keep in mind that this was a time when the long-term military importance of airpower was far from established in the general culture.  The armies and navies of the world generally assumed that aircraft were at best scouts and light raiders, incapable of turning the tide of a battle save by providing intelligence or scoring lucky hits.

The military establishments of c. 1930 were far from committed to scientific research.  New weapons emerged pretty much at random from industry during peacetime, to be purchased or ignored by the armies and navies as the mood took them.  The concept of technological superiority being crucial to victory in wartime was not yet universally accepted.

The military component of "Spawn of the Stars" is almost entirely about airpower and military research.  The Spawn strike from the sky with bombs capable of sinking whole naval squadrons or demolishing whole cities.  Likewise, humanity must take to the skies to fight back.  The only warships worth mentioning are aircraft carriers; the only artillery are anti-aircraft guns.  The only land action shown is the salvage of a crashed skysphere (a scene that became standard to later science fiction) against the opposition of its pilot.  The strike that delivers final human victory is delivered by a modified fighter plane, and could not have been delivered at all from the ground.

This is very progressive for 1930.  It foreshadows in many respects the strategic air war of 1939-45, particularly the destruction of whole cities by incendiary and nuclear bombing in the last two years of the war.  It was of course in part inspired by the German air campaign against the British from 1914-18 (the brief mention of a zeppelin would have sounded sinister to a reader c. 1930, and the destruction of Berlin in the story could be seen as karmic payback by a contemporary reader), but takes place on a much grander scale and is far more crucial to the outcome of the war.

What Happened Next?

Observant readers may have noticed that the situation is far from resolved.  The five Spawn skyspheres which attacked the Earth have all been downed, but we have no idea from where the Spawn have come, whether this was merely the vanguard of their attack, or even if there are still more Spawn, either in orbit (12).  It is easily believable that the Spawn will strike again:  furthermore, one would imagine that humanity might be interested in exploiting the alien technology that they have captured and building spacecraft of their own.  Clearly, the awareness that we are not alone, and that our neighbors are hostile, will affect the future of the human world.

One wishes for a sequel.

Conclusion:

This is a fun story, well worth reading and re-reading, and one seminal to the whole alien invasion genre.  I am now going to seek out more of Diffin's work, and wonder why he hasn't been more noticed by anthologists reprinting early science fiction.

=======================================================
Notes:

(1) - Ah, sweet Coincidence, the Muse without which so many pulp sf plots would utterly unravel!  On the other hand, we may assume that there were plenty of people who did not see an alien on the ground this early in the invasion:  it is in fact this encounter that makes the protagonist the protagonist, so it's not too jarring a coincidence.  The next coincidence will be one too many, though.

(2) - This is noteworthy as what is perhaps the first example of alien cattle mutilation in science fiction:  this may be the stem from which the whole concept sprang.  In this story the aliens are doing this to eat the cattle, which actually makes sense (granting compatible biologies):  it's much safer and easier for the aliens to kill and eat cattle (who can't fight back effectively) than it is for them to kill and eat humans (who can).

(3) - This is the really major coincidence of the story, and the least believable.  Why did the alien flyer come back?  If it was damaged in the Battle of San Diego, why did it stick around near human-habited areas for hours, rather than setting down in the wilderness to the east?  And wasn't it convenient that it came down so close to the heroes that they could follow it in a CAR

This is annoying, because Diffin could have as easily chosen to have it come down a hundred miles away, and had the heroes receive the report of this:  he chose coincidence just because he wanted to let us see the flyer crash.  In my opinion, it damages verisimilitude.

Perhaps I'm more sensitive to this than the original audience because, as someone who grew up with World War II air campaigns as part of the background, I'm aware of just how much distance a damaged fast subsonic aircraft can cover before it goes down.  Diffin and his audience were only personally familiar with the slow subsonic aircraft of the Great War, which you could have trailed in a (fast) car had the plane been damaged.

(4) - Radiation sickness was actually known as early as 1896, when Nikola Tesla intentionally exposed his fingers to X-rays to see what would happen.  Marie Curie, the most famous early victim of long-term radiation tissue damage, did not die until 1934.  It was not until 1945 and the scientific study of the aftereffects of radiation at Hiroshima and Nagasaki that people generally became aware of just how dangeorus can be hard radiation:  Diffin was being somewhat prophetic in realizing that the MacGregor Ray would be dangerous to humans as well as to the Spawn.

(5) - This death is biologically dubious (brief immersion in an unbreathable atmosphere wouldn't kill you any more than would brief immersion in water, and the supercompressed hydrogen would rapidly expand to ordinary diatomic hydrogen and rise into the air, restoring the oxygen to your environment).  It's also very obviously for the convenience of the plot, as otherwise MacGregor rather than Slim Riley would be flying the fighter plane at the end of the story.  And what's worse, it's unnecessary even for plot purposes:  had MacGregor instead set off a thermobaric explosion he might have quite plausibly been killed in the blast, and of course his messing-around with gamma radiation might well also have killed or at least crippled him.  It's one of the weakest elements of the story.

(6) - There is an obvious similarity here with the manner in which Russell Casse, also a traumatized war veteran fighter pilot, destroys one of the giant alien saucers in Independence Day.  I am not claiming that one was inspired by the other, because it's such an obvious plot element, but this may have been the first example of this particular kind of heroic sacrifice in science fiction.  For a different version of the same sort of thing, which may have inspired Diffin, consider the death ride of HMS Thunder Child in the novel War of the Worlds.

(7) - Triplanetary originally appeared in 1934, but the early version of this story covered only Gray Roger and the Nevian invasion:  it was not until the 1948 reprint that Triplanetary was retconned into the Lensman universe, with Gray Rogers being an incarnation of Gharlane of Eddore and the Triplanetary Patrol being the original form of the Galactic Patrol.

(8) - On the other hand, the fact that they eat whole HERDS of cattle may mean that they require certain nutrients which Earth life possesses only in very small quantities.  Though their shape-changing is probably metabolically-expensive, I would doubt that they would need to eat such vast quantities of their own kind of life.

(9) - Though it's interesting that all three named authors used amorphous aliens as villains.  Lovecraft never presents any even slightly sympathetic view of the Shoggoths, even though they were (by geologically-modern times) sapient slaves of the Elder Things  (for a sympathetic view of them, see Elizabeth Bear's "Shoggoths in Bloom").  Weinbaum's "doughpots," from "Parasite Planet," are non-sapient and eternally hungry -- about all one can do with them is incinerate them with flame-pistols.  And the far-too-sapient Eddorians are the source of all evil in the Lensman universe.  Humans just don't like giant blobs -- it seems ingrained in us, for some reason that I can't wholly fathom (since we didn't evolve being preyed on by such creatures).

A thought -- maybe what we're really afraid of is not blobs, but bogs.  Virtually every fictional description I've read of being attacked by a giant blob emphasizes being smothered, even though logically in some cases, what one should be noticing is not so much "smothering" as being torn apart (by shoggoths) or burned by digestive acids.  Now, if one falls into quicksand, one is not torn apart or burned, but one is most definitely smothered.  And humans, as semi-aquatic apes, evolved in an environment containing far too many bogs ...

(10) - In the pre-dawn of the Space Age, aircraft, shuttles and spaceships all tended to be conflated, and we never learn whether the Spawn sky-spheres are operating from a secret base on Earth, a mothership in orbit, or are themselves capable of crossing interplanetary or even interstellar distances on their own.  The spheres as described might be capable of attaining and landing from Earth orbit; they seem a bit small and their engines a bit puny for flight across interstellar distances. 

One reason why they may not be capable of interstellar travel is that the aliens are vulnerable to, and the flyer hulls do not seem very resistant to, hard electromagnetic radiation.  Any alien interplanetary cruiser would have to be better shielded than those flyers, especially on a long flight.  Diffin would have been unaware of this problem, as human scientists did not in 1930 grasp the magnitude of hard radiation put out by the Sun, especially into the Inner Solar System.

(11) - The Fithp are indeed rather pathetic:  they're a race of domestic animals Uplifted to intelligence who have learned their advanced technology by rote from pillars left by their former masters.  They don't really understand the Universe or see the possibilities of technological innovation; the group of Fithp who invade the Earth do so from perceived necessity (they are refugees from the losing side of a war); and after the initial shock, humanity's superior intelligence and imagination enables us to quickly adapt to their weapons and tactics -- in the end, they wind up re-domesticated, by America.

The Race is not as pathetic but they are somewhat admirable:  they are convinced that their ancient, incredibly-conservative civilization, similar in some respects to a rather humane sort of Oriental despotism, is the only way for sapient races which they perceive as "barbarians" to live in peace and harmony.  They expect to find the Earth at an Iron-Age level of technology, and when they find us instead at a late-Industrial tech level are not really quite sure what to do next.  They unimaginatively proceed with their invasion as planned, and suffer horribly as we learn and adapt to their weapons and tactics, and in the end this leads to Earth developing a technology beyond that of, and probably dooming, their ancient empire.

Neither the Fithp nor the Race are as malevolent as the Martians or the Spawn.  The Fithp want to fight and then politically domiante us, while the Race wants to "civilize" us.  Neither wish to exterminate humanity nor even crush our civilization:  they want to rule rather than destroy.

(12) - The very notion of an orbital presence would not have occurred to most sf writers or readers of 1930, even though Tsiolovsky had come up with the notion of artificial satellites some 40 years earlier.  The very first stories to mention orbital space stations were being written around the same time as this, specifically Jack Williamson's "Prince of Space" (in which such a station is a plot element):  see my review of this tale.  But they could have been up there, and the rather sparse design of the skyspheres implies that they were.
