A BESIEGED WORLD.

The medusa was clinging tenaciously to horse and rider when I shouted to Sue to turn her mount. She must have heard me, for the horse suddenly wheeled and came galloping in my direction.

I could not see Sue, who was completely enveloped by the cloud which surrounded her attacker, but knew that she must be struggling frantically in its clutches, from the way it moved.

Calling to Blue Streak, I seized his bridle, but he was so terrified he dragged me fully a hundred feet before I could bring him to a stop.

In the meantime the professor and Smith arrived with their guns and torches. They started in at once, burning the writhing tentacles first. This frightened the horse still more, and he pranced while I clung to the bridle.

It only took the two men a few minutes to get Sue out of the saddle and destroy the shrieking creature that had attacked her, but to me those minutes seemed like hours. She was unconscious, apparently from the electrical shocks. Giving Smith the reins to hold, I helped the professor as he bent over her, painting the tentacles that still encircled her body and arms with dilute prussic acid from the bottle he had in his pocket.

As I was chafing her hands I saw the last of the medusæ rise and sail away, avoiding us--probably because of the smell of its burned comrade. They had all escaped while we were fighting to save Sue. We took her to the house, where we left her under her mother's care.

That afternoon I drove to Sterling in the professor's sedan to get some oxy-acetylene torches which we planned to use as weapons of defense. As I sped along over the smooth concrete pavement I was surprised and horrified at the number of colonies of stalk medusæ that had sprung up overnight. Some of the cornfields were nearly obliterated by them. And in a few of the pastures I saw individuals undergoing the metamorphosis which indicated that they had been well fed.

Upon my arrival in Sterling, I stopped at a garage which I knew did welding, and tried to buy an outfit from them. They only had one, which was not for sale, but referred me to a wholesaler who would sell me as many outfits as I wanted.

I repaired to the office of the wholesaler, and bought three outfits with extra drums of gas, which I loaded into the back of the sedan. The wholesaler told me that the government had issued a warning to use only closed automobiles and airships. Several medusa, he said, had been shot down with anti-aircraft guns, but no means had been devised of dispatching them after they fell, and they had eventually escaped. Machine gun bullets fired from airplanes, he said, had proved ineffective, although some of the medusæ thus attacked had been noticed to fly erratically or sink slightly for a time.

The medusæ, he said, had spread to every continent of the world, and an international conference was being held for the purpose of devising a method of combating this menace to humanity.

I stopped at a grocery store and filled every available space in the car with bacon, ham, flour and canned goods. Then, after buying all the papers I could get containing news of the latest developments of the medusæ invasion, I took to the highway.

I got back to the farmhouse without incident, but the proximity of the stalk medusæ to the edges of the road made it evident that another such trip would soon be out of the question.

* * * * *

Smith and the professor met me as I drove up. The latter looked into the tonneau.

"Got three outfits, I see, and a supply of groceries. Good boy! We'll need them. Let Smith have the car, now, and come up to the house."

I got out, glad to stretch my cramped limbs, and turned the wheel over to Smith.

As the professor and I walked to the house together, he said:

"I've been watching these stalk medusæ, and have not only learned something about their feeding habits, but how they begin life on our earth."

"Really!" I replied. "That's important. Tell me about it."

"Yes. They begin life as microscopic, ribbon-like spores--the probable form in which they left Green's comet to colonize our earth. The weight of one of these spores, even in proportion to its minute size, is so infinitesimal that it can float for great distances in even the slightest air currents. It seems, also, to have some electro-magnetic faculty which enables it to seize and utilize magnetic lines of force, thus making it possible for it to travel in interplanetary and interstellar space. Its presence here seems to indicate that it has this power, and I have found it is unharmed by liquid air, which approaches the cold of space.

"As the creature is asexual, reproducing by division, a single spore arriving on any stellar body where life and growth are possible can quickly colonize that body.

"Having arrived on earth, I find that a spore immediately sends roots into the soil like a plant, but that it also extends its tentacles in the air in search of animal food. It thus feeds above and below the soil, becoming the stalk medusæ so horribly familiar to us. When it reaches a certain size, each stalk turns into twenty saucer-shaped disks, which soon become flying medusæ.

"At my suggestion, the government is now experimenting with flame-throwers as a means of combatting the menace. They are efficient for short distances and in such limited areas as can be covered by them, but they are far from being the solution of our problem. We must find some other, swifter way. I have ordered some supplies sent from Washington for the purpose of experimenting along these lines. They are being shipped to our local airport. But it will be difficult, if not impossible, to get them, as the roads are now blocked by the medusæ, as well as the fields and pastures."

"Can't they fly over us and drop them?" I asked.

"As the shipment will contain some very powerful explosives I'm afraid that wouldn't be practical," said the professor.

At this juncture Smith came in to report that the oxy-acetylene outfits were ready to use, and that quite a number of stalk medusæ were springing up around the house.

The professor and I went out and found that Smith had rigged up the outfits quite ingeniously. Each one was installed on a wheelbarrow with the nozzle fastened on the end of a twelve-foot bamboo pole. This pole was laid across a rack which Smith had built on the front of the vehicle, enabling a man to move the outfit about without having to hold onto the pole or turn out the gas.

Each of us took one of the outfits and immediately began the war of extermination against the stalk medusæ surrounding the house and other buildings. It was slow work, as there were thousands of them. But after several hours of strenuous endeavor, we had spaces cleared around the buildings wide enough to forestall any immediate attacks from these creatures.

We then turned our weapons over to the three remaining farm hands, who, under Smith's supervision, began widening the clear space we had made. The professor and I returned to the house.

Scarcely had we entered the drawing-room when the voice of a very excellent soprano who was singing over the radio was suddenly stilled, and an announcer cut in:

"Sorry to have to interrupt the program," he said, "but I have just received an important announcement by telephone. The Chicago air scouts report that an immense number of the flying, cloud-hidden monsters that are menacing the world are congregating far out over Lake Michigan. The attention of the scout fleet was first drawn to them by hideous, howling noises, so loud that even at a distance of a mile they were easily audible above the roaring of the airplane propellers. Upon investigating, the scouts saw the monsters forming in a long line not more than two hundred feet above the surface of the lake.

"These strange creatures appeared to be carrying on an intelligent conversation with each other by means of their terrific howls, and at times, seemed to be silenced by a leader, which addressed them all collectively. They are now bearing down on the City of Chicago, and every person is warned to stay within doors, keeping all doors and windows closed.

"Regardless of the heat, fires should be immediately kindled in all furnaces, boilers, stoves and fireplaces as a measure of defense. It is thought that the smoke, cinders and sparks may be distasteful to the monsters, and the fire will keep them from reaching down chimneys with their deadly tentacles. Our air force is trying to break up the line by dropping bombs on it, but as fast as a gap is opened the creatures close it once more. Take heed, everybody, on peril of your lives! Stay inside. Keep doors and windows locked. Build fires."

"Just as I feared," said the professor. "These creatures from another world, perhaps from another universe, are more intelligent than they at first appeared to be. They are beginning, now, to work in groups--to exercise their intelligence as well as their instinct for the capture of food. Man has proved a wily and elusive food morsel, so they are uniting forces and _trawling_ for him. Think of it, Dick! A group of monsters from outside space trawling for men, exactly as men trawl for fish! Seems incredible, doesn't it?"

"It does," I answered. "It also seems impossible that they should have suddenly begun talking to each other. So far as we have heard, none of these creatures talked to each other before."

"I don't see anything so surprising about that," said the professor. "We discovered that they had voices, and powerful ones, when I burned the one that attacked you. It is quite possible that, although endowed with voices as soon as they reach the flying stage, they do not actually learn to converse until they reach a certain stage of development. This is true of all creatures with voices--true of man himself.

"A peculiarity of the flying medusæ is that they make no sound when cut or blown to pieces. Cutting, puncturing or tearing them evidently does not hurt them. They seem to know, instinctively, that it will not kill them, but is actually a form of artificial reproduction by fission, as each fragment will eventually become a new individual. Burning, however, is different. Burning destroys the living tissues beyond repair. And when they are burned, they shriek. They evidently know that burning means death."

* * * * *

The professor paused, then spoke very solemnly: "Dick, we have a greater menace in the medusæ than even I, who recognized their extremely dangerous character from the first, ever thought possible. There is no telling how intelligent they are, or what faculties they can develop in adapting themselves to terrestrial environment. It is evident that the adults, at least, have auditory organs. They could not converse vocally without them.

"They apparently have a sense of smell, also, by which they locate their prey. The swift motion of the prey evidently aids this sense, just as waving a bottle of perfume beneath the nostrils makes the aroma more rapidly perceptible than when it is held still.

"They have, I have concluded, no organs of sight--or only imperfectly developed ones. No doubt the comet on which we believe they came has been away from the sun for so many thousands of years that its surface was constantly in darkness. The light from the meteoroids of the coma, when they are made incandescent by passage through the upper regions of the comet's atmosphere, could scarcely penetrate the thick clouds which our astronomers observed as in more than an exceedingly dim twilight. Under the circumstances, organs of sight would have been useless, and would probably have atrophied had the creatures originally possessed them.

"It may be that under the conditions which they find on our planet, these monsters will be able to develop their organs of sight. Nor have we plumbed the limit of their intelligence. They may, for all we know, be as intelligent as man himself, or more so."

At this moment Wong entered, and bowed obsequiously.

"Captain Felton like make talk Plofessey Davis along telumphone," he announced.

"Excuse me," said the professor. "It's probably news of the supplies from Washington."

He went to the writing desk and picked up the receiver-transmitter.

"Yes, captain?...

"They are here, you say? I don't know how I'll be able to get them."

"Tell him I'll be over after them," I said.

"All right, captain. We'll see what we can do."

Putting down the phone he turned to me.

"Don't be foolhardy, Dick," he said. "You can't go to that airport on the ground, and you have no means of flying there. Why, the attempt would be suicidal."

"Nevertheless," I replied, "I have a plan for getting through, and I believe I can make it work."
