Invaders of Earth

by Groff Conklin

  “Cold front coming down from Saskatchewan,” the Chief said as he came in and looked over our charts. We were getting ready to leave. “Unusual for this time of year.”

  I nodded, unworried. We had the mountains between us and any cold wave from that direction. We wouldn’t freeze at night even if the cold got down as far as Casper, which would be highly unlikely. The Chief was bending low over the map, tracing out the various lows and highs. He frowned a bit when he came to a new little low I had traced in from the first reports of that day.

  “An unreported low turning up just off Washington state. That’s really odd. Since when are storms originating so close?”

  “Coming east, too, and growing, according to Seattle’s wire,” said Ed. The Chief sat down and stared at the map.

  “I don’t like it, it’s all out of whack,” he said. Then he stood up and held out his hand to me.

  “Well, good-by, boys, and have a good time. If you find that meteor, bring me back a chunk, too.”

  “Sure will,” I said, and we shook hands and yelled at the other boys and went out.

  The first rays of the sun were just coming up as we left. Outwards we jogged, the town and civilization fell behind rapidly, and we went on into the golden glow of the Sweetwater basin.

  We made good time that day, though we didn’t hurry. We kept up a nice steady trot, resting now and then. We didn’t talk much, for we were too busy just breathing in the clean open air and enjoying the sensation of freedom. An occasional desert toad or the flash of a disturbed snake were the only signs of life we saw, and the multiform shapes of the cactus and sage our only garden. It was enough.

  Toward evening, at the Bureau, the Chief first noted the slight growth of the southern warm front. A report from Utah set him buzzing. The cold front had now reached the borders of Wyoming and was still moving on. The baby storm that was born where it had no right to be born was still growing and now occupied a large area over Oregon and Idaho. The Chief was heard to remark that the conjunction of things seemed to place southwest Wyoming as a possible center of lots of wild weather. He started worrying a bit about us, too.

  We didn’t worry. We didn’t have any real indications, but our weathermen’s senses acted aright. We felt a sort of odd expectancy in the air as we camped. Nothing definite—a sort of extra stillness in the air, as if forces were pressing from all sides, forces that were still far away and still vague.

  We spoke a bit around the fire about the storm that the Chief had noted when we left. Ed thought it would fizzle out. I think I had a feeling then that it wasn’t just a short-lived freak. I think I had an idea we might see something of it.

  Next morning there was just the faintest trace of extra chill in the air. I’m used to Wyoming mornings and I know just how cold it ought to be at sunrise and how hot. This morning it was just the slightest bit colder.

  “That Canadian cold front must have reached the other side of the mountains,” I said, waving toward the great rampart of the Rockies to the East. “We’re probably feeling the only tendril of it to get over.”

  “That’s sort of odd,” Ed said. “There shouldn’t be any getting over at all. It must be a very powerful front.”

  I nodded and wondered what the boys in the Bureau were getting on it. Probably snowfall in the northern part of the state. If I had known what the Chief knew that morning, I might have started back in a hurry. But neither of us did, and I guess we saw something that no one else has, as a result.

  For, at the Bureau, the Chief knew that morning that we were in for some extraordinary weather. He predicted for the Rock Springs paper the wildest storm ever. You see, the southern warm front had definitely gotten a salient through by that time. It was already giving Salt Lake City one of the hottest days on record, and what was more, the warm wave was coming our way steadily.

  The next thing was that storm from the west. It was growing smaller and tighter again and had passed over Idaho Falls two hours earlier, raging and squalling. It was heading in our direction like an arrow from a bow.

  And finally the cold front had done the impossible. It was beginning to sweep over the heights and to swoop down into the Divide Basin, heading straight for the warm front coming north.

  And there were Ed and I with a premonition and nothing more. We were riding along right into the conflux of the whole mess, and we were looking for meteors. We were looking for what we expected to be some big craters or pockmarks in the ground and a bunch of pitted iron rocks scattered around a vicinity of several miles.

  Toward ten that morning we came over a slight rise and dipped down into a bowl-shaped region. I stopped and stared around. Ed wheeled and came back.

  “What’s up?” he asked.

  “Notice anything funny in the air?” I asked and gave a deep sniff.

  Ed drew in some sharp breaths and stared around.

  “Sort of odd,” he finally admitted. “Nothing I can place, but it’s sort of odd.”

  “Yes,” I answered. “Odd is the word. I can’t place anything wrong, but it seems to smell differently than the air did a few minutes ago.” I stared around and wrinkled my brow.

  “I think I know now,” I finally said. “The temperature’s changed somewhat. It’s warmer.”

  Ed frowned. “Colder, I’d say.”

  I became puzzled. I waved my hands through the air a bit. “I think you’re right; I must be wrong. Now it feels a bit colder.”

  Ed walked his horse a bit. I stared after him.

  “Y’know,” I finally said, “I think I’ve got it. It’s colder, but it smells like warm air. I don’t know if you can quite understand what I’m driving at. It smells as if the temperature should be steaming, yet actually it’s sort of chilly. It doesn’t smell natural.”

  Ed nodded. He was puzzled, and so was I. There was something wrong here. Something that got on our nerves.

  Far ahead I saw something sparkle. I stared as we rode and then mentioned it to Ed. He looked, too.

  There was something, no, several things far off at the edge of the bowl near the next rise, that glistened. They looked like bits of glass.

  “The meteor, maybe?” queried Ed. I shrugged. We rode on steadily in that direction.

  “Say, something smells funny here,” Ed remarked, stopping again.

  I came up next to him. He was right. The sense of strangeness in the air had increased, the nearer we got to the glistening things. It was still the same—warm-cold. There was something else again. Something like vegetation in the air. Like something growing, only there still wasn’t any more growth than the usual cactus and sage. It smelled differently from any other growing things, and yet it smelled like vegetation.

  It was unearthly, that air. I can’t describe it any other way. It was unearthly. Plant smells that couldn’t come from any plant or forest I ever encountered, a cold warmness unlike anything that meteorology records.

  Yet it wasn’t bad, it wasn’t frightening. It was just peculiar. It was mystifying.

  We could see the sparkling things now. They were like bubbles of glass. Big, iridescent, glassy balls lying like some giant child’s marbles on the desert.

  We knew then that, if they were the meteors, they were like none that had ever been recorded before. We knew we had made a find that would go on record, and yet we weren’t elated. We were ill at ease. It was the funny weather that did it.

  I noticed then for the first time that there were black clouds beginning to show far in the west. It was the first wave of the storm.

  We rode nearer the strange bubbles. We could see them clearly now. They seemed cracked a bit, as if they had broken. One had a gaping hole in its side. It must have been hollow, just a glassy shell.

  Ed and I stopped short at the same time. Or rather our horses did. We were willing, too, but our mounts got the idea just as quickly. It was the smell.

  There was a new odor in the air. A sudden one. It had just that instant wafted across our nostrils. It was at first rep
elling. That’s why we stopped. But sniffing it a bit took a little of the repulsion away. It wasn’t so very awful.

  In fact, it wasn’t actually bad. It was hard to describe. Not exactly like anything I’ve ever smelled before. Vaguely it was acrid, and vaguely it was dry. Mostly I would say that it smelled like a curious mixture of burning rubber and zinc ointment.

  It grew stronger as we sat there, and then it began to die away a bit as a slight breeze moved it on. We both got the impression at the same time that it had come from the broken glass bubble.

  We rode on cautiously.

  “Maybe the meteors landed in an alkali pool and there’s been some chemical reaction going on,” I opined to Ed.

  “Could be,” he said, and we rode nearer.

  The black clouds were piling up now in the west, and a faint breeze began to stir. Ed and I dismounted to look into the odd meteors.

  “Looks like we better get under cover till it blows over,” he remarked.

  “We’ve got a few minutes, I think,” I replied. “Besides, by the rise right here is just about the best cover around.”

  Back at the Weather Station, the temperature was rising steadily and the Chief was getting everything battened down. The storm was coming next, and, meeting the thin edge of the warm-front wedge which was now passing Rock Springs, would create havoc. Then the cold wave might get that far because it was over the Divide. In a few minutes all hell would break loose. The Chief wondered where we were.

  We were looking into the hole in the nearest bubble. The things— they must have been the meteors we were looking for—were about twelve feet in diameter and pretty nearly perfect spheres. They were thick-shelled and smooth and very glassy and iridescent and like mother-of-pearl on the inside. They were quite hollow, and we couldn’t figure out what they were made of and what they could be. Nothing I had read or learned could explain the things. That they were meteoric in origin I was sure because there was the evidence of the scattered ground and broken rocks about to show the impact. Yet they must have been terrifically strong or something, because, save for the few cracks and the hole in one, they were intact.

  Inside, they stank of that rubber-zinc smell. It was powerful. Very powerful.

  The stink had obviously come from the bubbles—there was no pool around.

  It suddenly occurred to me that we had breathed air of some other world. For if these things were meteoric and the smell had come from the inside, then it was no air of Earth that smelled like burning rubber and zinc ointment. It was the air of somewhere, I don’t know where, somewhere out among the endless reaches of the stars. Somewhere out there, out beyond the sun.

  Another thought occurred to me.

  “Do you think these things could have carried some creatures?” I asked. Ed stared at me a while, bit his lip, looked slowly around. He shrugged his shoulders without saying anything.

  “The oddness of the air,” I went on, “maybe it was like the air of some other world. Maybe they were trying to make our own air more breathable to them?”

  Ed didn’t answer that one, either. It didn’t require any. And he didn’t ask me who I meant by “they.”

  “And what makes the stink?” Ed finally commented. This time I shrugged.

  Around us the smell waxed and waned. As if breezes were playing with a stream of noxious vapor. And yet, I suddenly realized, no breezes were blowing. The air was quite still. But still the smell grew stronger at one moment and weaker at another.

  It was as if some creature were moving silently about, leaving no trace of itself save its scent.

  “Look!” said Ed suddenly. He pointed to the west. I looked and stared at the sky. The whole west was a mass of seething dark clouds. But it was a curiously arrested mass. There was a sharply defined edge to the area—an edge of blue against which the black clouds piled in vain, and we could see lightning crackle and flash in the storm. Yet no wind reached us, and no thunder, and the sky was serene and blue overhead.

  It looked as if the storm had come up against a solid obstacle, beyond which it could go no farther. But there was no such obstacle visible.

  As a meteorologist I knew that meant there must be a powerful opposing bank of air shielding us. We could not see it, for air is invisible, but it must be there, straining against the cloud bank.

  I noticed now that a pressure was growing in my ears. Something was concentrating around this area. We were in for it if the forces of the air ever broke through. Suddenly, the stink welled up powerfully. More so than it had before. It seemed to pass by us and through us and around us. Then, again, it was gone. It almost vanished from everything. We could detect but the faintest traces of it after that passage.

  Ed and I rode out to an outcropping of rock. We dismounted. We got well under the rock and we waited. It wouldn’t be long before the protecting air bank gave way.

  To the south, now, storm clouds materialized, and then finally to the east and north. As I learned later, the cold wave had eddied around us and met the equatorial front at last, and now we were huddled with some inexplicable globes from unknown space and a bunch of strange stinks and atmosphere, ringed around by a seething, raging sea of storm. And yet above, the sky was still blue and clear.

  We were in the midst of a dead center, in the midst of an inexplicable high pressure area, most of whose air did not originate on Earth, and the powers of the Earth’s atmosphere were hurling themselves against us from every direction.

  I saw that the area of clear was slowly but surely contracting. A lancing, freezing breeze suddenly enveloped us. A breath rough from the north. But it seemed to become curiously blunted and broken up by countless thrusts of the oddly reeking air. I realized, as the jet of cold air reached my lungs, how different the atmosphere was in this pocket from that we are accustomed to breathe. It was truly alien.

  And yet always this strange air seemed to resist the advances of the normal. Another slight breeze, this one wet and warm, came in from the south, and again a whirl of the rubbery-odored wind dispersed it.

  Then there came an intolerable moment. A moment of terrific compression and rise, and the black storm clouds tore through in wild streaks overhead and spiderwebbed the sky rapidly into total darkness. The area of peace became narrow, restricted, enclosed by walls of lightning-shot storm.

  I got an odd impression then. That we were embattled. That the forces of nature were determined to annihilate and utterly rip apart our little region of invading alien air, that the meteor gases were determined to resist to the last, determined to keep their curious stinks intact!

  The lightning flashed and flashed. Endless giant bolts, yet always outside our region. And we heard them only when a lance of cold or hot storm pierced through to us. The alien air clearly would not transmit the sounds; it was standing rigid against the interrupting vibrations!

  Ed and I have conferred since then. We both agree that we had the same impressions. That a genuine life-and-death fight was going on. That that pocket of other-worldly air seemed to be consciously fighting to keep itself from being absorbed by the storm, from being diffused to total destruction so that no atom of the unearthly gases could exist save as incredibly rare elements in the total atmosphere of the Earth. It seemed to be trying to maintain its entirety, its identity.

  It was in that last period that Ed and I saw the inexplicable things. We saw the things that don’t make sense. For we saw part of the clear area suddenly contract as if some of the defending force had been withdrawn, and we saw suddenly one of the glass globes, one of the least cracked, whirl up from the ground and rush into the storm, rush straight up!

  It was moving through the clear air without any visible propulsion. We thought then that perhaps a jet of the storm had pierced through to carry it up, as a ball will ride on a jet of water. But no, for the globe hurled itself into the storm, contrary to the direction of the winds, against the forces of the storm.

  The globe was trying to break through the ceiling of black to the
clear air above. But the constant lightning that flickered around it kept it in our sight. Again and again it darted against the mass of clouds and was hurled wildly and furiously about. For a moment we thought it would force its way out of our sight, and then there was a sudden flash and a sharp snap that even we heard, and a few fragments of glassy stuff came falling down.
