Chapter XII (2)

Carnes gasped as he looked up and saw the surface of the water above him. Dr. Bird laughed again and turned to the telephone.

"Lower away," he said. "Everything is tight."

* * * * *

The globe descended into the depths of the sea. Darker and darker it grew until only a faint twilight glow filled the sphere. A dark bulk loomed before them. Dr. Bird snapped on one of his huge floodlights and pointed.

"The _Arethusa_," he said.

The ill-fated vessel lay on her side with a huge jagged hole torn in her fabric amidships.

"That's where her boilers burst," explained the Doctor. "Luckily we have a hard bottom to deal with. Let's see if we can locate any of Mitchell's sea serpents."

He turned on other flood lights and swept the bottom of the sea with them. The huge beams bored out into the water for a quarter of a mile, but nothing unusual was to be seen. Dr. Bird turned his attention again to the wreck.

"Things look normal from this side," he said after a prolonged scrutiny. "I'll have the _Minneconsin_ steam around it while we look it over."

In response to his telephone orders the ship above them swung around the wreck in a circle, and Carnes and the Doctor viewed each side in turn. But nothing of a suspicious nature made its appearance. The sphere stopped opposite the hole in the side and Dr. Bird turned to Carnes.

"I'm going to put on a diving suit and explore that wreck," he said. "If there ever was any danger, it isn't apparent now; and I can't find out anything until I get inside."

"Don't do it, Doctor!" cried Carnes. "Remember what happened to the other divers!"

* * * * *

"We don't know what happened to them, Carnes. No matter what it was, there is no danger apparent right now, and I've got to get into that ship before I can get any real information. We could have lowered an under-sea camera and learned as much as we have so far."

"Let me go instead of you, Doctor."

"I'm sorry to refuse you, old dear, but frankly, I wouldn't trust your judgment as to what you had seen if you went alone; and we can't both go."

"Why not?"

"If we both went, who would work the air to let us back in? No, this is a one-man job and I'm the one to do it. While I am gone, keep a sharp lookout, and if you see anything unusual call me at once."

"How can I call you?"

"On this small radio phone. A pair of receivers tuned to the right wave-length are in my diving helmet, and I will be able to hear you although I can't reply. I won't be gone long: I have only a small air tank, large enough to keep me going for thirty minutes. Now help me into my suit and keep a sharp watch. A timely warning may save my life if anything happens."

With Carnes' assistance, Dr. Bird donned a deep-sea diving outfit and screwed down the helmet. He crawled through the inner door into the lock and lifted the inner door into place. Carnes fastened the door with nuts and the Doctor opened a pair of valves in the outer door and filled the lock with water. He removed the outer door; and, taking in one hand a steel-shod twelve-foot pike with a hook on the end, and in the other a waterproof flashlight, he sallied forth. As he left the shell he paused for a moment, and then returned and picked up the heavy wrench with which he had removed the nuts holding the outer door into place. He fastened the tool to the belt of his suit. Then, with a wave of his hand toward the detective, he approached the hulk.

The hole in the side was too high for him to reach, but he hooked the end of his pike in one of the joints of the _Arethusa's_ plates and climbed slowly and painfully up the side of the vessel. As he disappeared into the hull, Carnes realized with a sudden start that he had been watching his friend and neglecting the duty imposed on him of keeping a sharp watch. He turned quickly to the floodlights and searched the sea bottom.

* * * * *

Nothing appeared, and the minutes moved as slowly as hours should. Carnes felt that he had been submerged alone for weeks, and his nerves grew so tense that he felt that he would scream in another instant. A sudden thought sobered him like a dash of cold water. If he screamed, Dr. Bird would take it for an alarm signal and possibly be afraid to emerge from the vessel. His watch showed him that the Doctor had been gone for twenty-five minutes and he moved slowly to the radio transmitter.

"Dr. Bird," he said slowly and distinctly, "you have been gone nearly thirty minutes. Nothing alarming has appeared but I will feel better when I see you coming back."

He glued his eyes on the opening in the ship's side and waited. Five minutes passed, and then ten, with no signs of the Doctor. Carnes moved again to the receiver.

"It has been over half an hour. Doctor," he cried in a pleading voice. "If you are all right, for God's sake show yourself. I am frantic with worry."

Another five minutes passed, and the sweat dripped in a steady stream from the detective's chin. Suddenly he gave a sob of relief and sank back against the side of the globe. A bulky figure showed at the edge of the hole, and Dr. Bird climbed slowly and heavily out of the hold and dropped to the sea bottom. He lay prone for a moment before he rose and made his way with evident effort toward the sphere. He entered the compartment and with a heroic effort lifted the outer door into place, and feebly and with fumbling fingers placed nuts on the bolts. His hands wandered uncertainly toward the valves and closed the upper one. He waved his hand toward Carnes and sank in a heap on the floor of the lock.

* * * * *

With trembling hands Carnes connected the air and opened the valve. Air flowed into the lock and the water was gradually forced out. When the lock was empty, he waited for Dr. Bird to close the outer valve but the Doctor did not move. Carnes tore at the bolts which held the inner door and threw his weight against it. It held against his assault, and he thought frantically. An inspiration came to him, and he disconnected the air valve. With a whistling rush, the air from the lock rushed into the sphere and he forced open the inner door. A stream of sea water drove against his feet through the open valve, and he reached for the valve to close it. The force of the water held it open for a moment, but he threw every ounce of his strength into the effort. The valve slowly closed.

It was beyond his strength to haul the heavy Doctor with his pressure diving suit through the restricted confines of the inner door, so Carnes wormed his way into the lock and with trembling fingers unscrewed the helmet of the Doctor's diving suit. The helmet clanged to the floor and Carnes scooped up his hands full of water and dashed it into the Doctor's face. There was no response and he was at his wit's end. He sprang for the radio to order the sphere hauled up when his glance fell on the oxygen tank. It took him only a moment to connect a rubber hose to the tank, and in a few seconds a blast of the life-giving gas was blowing into the scientist's face. Dr. Bird gave a convulsive gasp or two and opened his eyes.

"Shut off the juice, Carnes," he said faintly. "Too much of that's bad."

Carnes shut off the oxygen and Dr. Bird struggled to a sitting position and inhaled deep breaths.

"That was a narrow squeak, old dear," he said faintly. "Give me a hand and I'll climb in."

* * * * *

With the detective's aid he climbed into the sphere and Carnes fastened the inner door. Slowly the Doctor rid himself of the diving suit and lay prone on the floor, his breath still coming in gasps.

"Thanks for your warning about the time, Carnes," he said. "I knew that my air supply was running short but I was caught down there and couldn't readily free myself. I thought for a while that my time had come, but it wasn't so written. By the looks of things, I freed myself just in time."

"Did you find out anything?" asked the detective eagerly.

"I did," replied Dr. Bird grimly. "For one thing, the gold is no longer in the hold of the _Arethusa_."

"It's gone?"

"Clean as a whistle, every bar of it. A hole has been cut in the vault around the combination, and the bars slid back and the door opened. The gold has been stolen."

"Might it not have been stolen before the vessel sank?"

"The idea occurred to me of course, and I examined things pretty carefully. I know that the theft occurred after the vessel sank."

"How could you tell?"

"For one thing, the hole was cut with an under-water cutting torch. For the second, look here."

* * * * *

The Doctor rolled up his trousers and showed the detective his leg. Carnes cried out as he saw huge purple welts on it.

"What caused that?" he cried.

"As I entered the vault, I stepped full into a steel bear trap which was set there for the purpose of catching and holding anyone who entered. Someone has visited the _Arethusa_, since she sank, and looted her, and also arranged so that any diver who got as far as the vault would never return to the surface to tell of it. Luckily for myself, I carried a heavy wrench and was able to free myself. Most divers don't carry such a thing."

"But who could have done it?"

"That's what we have got to find out, and we aren't going to do it down here. Give the word to have us hauled up; and, Carnes, don't mention anything about the looting of the vessel. Allow it to be understood that I couldn't get into the hold. We'll head back for New York at once. I want to have a few small changes made in this sphere before we use it again. While I am doing that, I want you to get hold of the Coast Guard or the Immigration Service or whoever it is that has the complete records in that case of alien smuggling, by the Young Labor party. When you get the information, report to me and we'll go over it. You might also drop a hint to Captain Starley that will stop all further attempts at salvage operations for a few days. Tell him that I'll arrange to have a Coast Guard cutter guard the locality of the wreck."

"Won't that be rather risky for the cutter?"

"I think not. The gold is gone and there is no reason to apprehend any further danger in that locality, at least for the present."

* * * * *

At nine o'clock next morning Carnes and Dr. Bird sat in the office of Lieutenant Commander Minden of the United States Coast Guard, listening intently to the history of the alien smuggling case. Commander Minden was saying:

"Their boats would load up and clear ostensibly for Rio de Janeiro or some other South American port, but once they were in the Atlantic, they would alter their course and head from the Massachusetts coast. Of course, we had no right to interfere with them on the high seas, and they never came closer than fifty miles of our coast line. When they got that close, they would cruise slowly back and forth for a few days and then steam away south to the port they had cleared for. When they got there, of course there were no passengers on board.

"We patrolled the coast carefully while they were around but we never got any indication of any landing of aliens and yet we knew they were being landed in some way. We drew lines so close that a cork couldn't get by without being seen and we even had the air patrolled, but with no results. Eventually the air patrol was the thing that gave them away.

"They had been operating so successfully that they evidently got careless and started a load off late in the night so they didn't reach the coast by dawn. A Navy plane was flying along the coast-line about twelve miles off when they spotted a submarine running parallel with the coast, headed north. It didn't look like an American craft and they went on and radioed Washington and found that we had no under-sea craft in that neighborhood. They returned to their patrol and followed the sub for a matter of thirty or forty miles up the coast, and then it turned in right toward the shore. The shore line there is rocky, and, at the point where the sub was heading, it falls sheer about two hundred fathoms. The sub ran right at the cliff and disappeared from view."

* * * * *

Lieutenant Commander Minden paused impressively. Carnes and Dr. Bird set forward in their chairs, for it was evident that the crux of the story was at hand.

"When the plane reported what they had seen, we knew how those aliens were being landed. The point where the sub went in gave us a good idea of the location of their base and we threw a cordon of men around and searched. A Navy sub was sent to the scene and they reported that there was a tunnel opening into the rock, about a hundred fathoms under water, running for they had no idea how far under the land. They stayed to guard the hole while we combed the land. It took us a week to locate the place, but we traced some truck loads of food and finally found it. This tunnel ran under the land for a mile and then ended in a large cave underground. The Young Labor party had established a regular receiving depot there, and took the aliens from the sub and kept them for a day or two until they had a chance to load them into trucks and run them into Boston or some other town in the night.

"Once we had the place spotted, we sent a gang in and captured the whole works without any trouble. The underground cavern had no natural opening to the surface, but one had been made by blasting. We captured the whole lot and then sealed the end of the hole with rock and concrete. That was the end of the affair."

"Thank you, Commander; you have given us a very graphic description of it. I suppose you could find the entrance which was sealed up?"

* * * * *

"Easily. I led the raiding party. I forgot to mention one blunder we made. Evidently some word of our plans leaked out, for the sub which was guarding the outer end of the tunnel was called away by a radio message supposed to be from the Navy Department. It had gone only a short distance, however, when the commander smelled a rat and made his way back. He was too late. He was just in time to see the sub emerge from the hole and head into the open sea. He gave chase, but the other sub was faster than the Navy boat and it got clear away. The leader of the gang must have been on it, for we didn't get him."

"Who was the leader?"

"From some records we captured, his name was Ivan Saranoff. I never saw him."

"Saranoff?" said Dr. Bird thoughtfully. "The name seems familiar. Where have I--Thunder! I know now. He was at one time a member of the faculty of St. Petersburg. He was one of the leading biologists of his time. Carnes, we've found our man."

"If you are thinking of Saranoff, I am afraid you are mistaken, Doctor," said Commander Minden. "Neither he nor his submarine have ever been heard of since and it has been generally conceded that they were lost at sea. We had some pretty rough weather just after that affair."

"Rough weather doesn't mean much to a sub, Commander. I expect that he's our man. At any rate, the place we want to go is the end of that tunnel."

"I'm at your service, Doctor."

"Carnes, get the location of that tunnel entrance from Commander Minden and order the _Minneconsin_ to proceed north along the coast to that vicinity and stand by for radio orders. I am going to telephone Mitchell Field and get a plane. We have no time to lose."

* * * * *

The plane from Mitchell Field roared down to a landing, and Carnes, Dr. Bird and Commander Minden dismounted from the rear cockpit and looked around. They had landed in a smooth field at the base of a rise almost rugged enough to be called a mountain. A group of three men were standing near them as they got out of the plane. One of the men approached.

"Dr. Bird?" asked the newcomer. "I am Tom Harron, United States Marshal. These two men are deputies. I understand that I am to report to you for orders."

"I'm glad to know you, Mr. Harron. This is Operative Carnes of the Secret Service and Commander Minden of the Coast Guard. We are going to explore an underground cavern that is located in this vicinity."

"Do you mean the one where they used to smuggle aliens? That is closed up. I was in charge of that work and we closed it tight as a drum two years ago."

"Can you find the entrance?"

"Sure. It isn't over a mile from here."

"Lead the way, then. We want to take a look at it."

The marshal led the way toward the eminence and took a path which led up a gully in its side. He paused for a moment to take his bearings and then turned sharply to his left and climbed part way up the side of the ravine.

"Here it is," he announced. An expression of astonishment crossed his face and he examined the ground closely. "By Golly, Doc," he went on as he straightened up, "this place has been opened since I left it!"

* * * * *

Dr. Bird hurried forward and joined him. The heavy stone and concrete with which the entrance to the cavern had been sealed were undisturbed, but in the side of the hill was set a steel door beside the concrete. There was no sign of a keyhole or other means of entering it.

"Was this steel door part of your work?" asked Carnes.

"No, sir, it wasn't. We sealed it solid. That door has been put there since."

Dr. Bird closely examined the structure. He tapped it and went around the edges and then straightened up and took a small pocket compass from his pocket and opened the case. The needle swung crazily for a moment and then pointed straight toward the door.

"A magnetic lock," he exclaimed. "If we could find the power line it would be easy to force, but finding that line might take us a week. At any rate, we have found out what we were after. This is their base from which they are operating. Mr. Harron, I want you to station a guard armed with rifles at this door day and night until I personally relieve you. Remember, until I relieve you, in person. Verbal or written orders don't go. Capture or kill anyone who tries to enter or leave the cavern through this entrance. Just now we'll find that cavern more vulnerable from the sea end, and that is where I mean to attack. We'll force that door and explore from this end later. Commander Minden, you may stay here with Mr. Harron, if you like, or you may come with Carnes and me. We are going on board the _Minneconsin_."

* * * * *

The Mitchell Field plane roared to a take-off and bore south along the coast. Half an hour of flying brought them in view of the battleship steaming at full speed up the coast. Dr. Bird radioed instructions to the ship, and an hour later a launch picked them up from the beach and took them out. As soon as they were on board they resumed their progress, and in two hours the peak that Dr. Bird had marked as a landmark was opposite.

"Steam in as close to the shore as you can safely," he said, "and then lower us. Once we are down, you will be guided by our telephoned instructions. Come on, Carnes, let's go."

The detective followed him into the sphere as the _Minneconsin_ edged up toward the shore. The huge ball was lifted from the deck and lowered gently into two hundred fathoms of water. It was pitch dark at that depth, and Dr. Bird switched on one floodlight and studied the cliff which rose a hundred yards from them.

"We have missed the place, Carnes," he said. "We'll have them pull us up a few hundred feet and then steam along the coast."

He turned to the telephone and the sphere rose while the battleship steamed slowly ahead, the vitrilene ball following in her wake. For a quarter of a mile they continued on their way, and then Dr. Bird halted the ship.

"What depth are we?" he asked. "Eighty fathoms? All right, lower us, please."

* * * * *

The ball sank until it rested on the sea bottom, and Dr. Bird turned on two additional floodlights and studied the surroundings. The bed of the ocean was literally covered with lobster and crab shell, with the bones of fish scattered here and there among them. A few bones of land animals were mixed with the debris and Carnes gave a gasp as Dr. Bird pointed out to him a diving helmet.

"We are on the right track," said the scientist grimly. He stepped to the telephone and ordered the sphere raised to one hundred fathoms. The ship moved forward along the coast until Dr. Bird again stepped to the telephone and halted it. Before them yawned the entrance to the underground tunnel. It was about two hundred feet high and three hundred across, and their most powerful beams would not penetrate to the end of it. A pile of debris could be seen on the floor of the tunnel and Carnes fancied that he could see another diving helmet among the litter. Dr. Bird pointed toward the side of the cavern.

"See those floodlights fastened to the cliff so that their beams will sweep across the mouth of the tunnel when they are lighted?" he said. "Apparently the cave is used as a prison and the light beams are the bars. The creature is not at home just now or the bars would be up. My God! Look at that, Carnes!"

Carnes stared and echoed the Doctor's cry of surprise. Clinging to a shelf of rock which extended out from the wall of the cavern and half hidden among the seaweed was a huge marine creature. It looked like a huge black slug with rudimentary eyes and mouth. The thing was fifty feet in length and fully fifteen feet in diameter. It hung there, moving sluggishly as though breathing, and rudimentary tentacles projecting from one end moved in the water.

"What is it, Doctor?" asked Carnes in a voice of awe.

"It is a typical trochosphere of the giant octopus, the devil fish of Indian Ocean legend, multiplied a thousand times," he replied. "When the octopus lays its eggs, they hatch out into the larval form. The free swimming larva is known as a trochosphere, and I am positive that that is what we see; but look at the size of the thing! Man alive, if that ever developed, I can't conceive of its dimensions!"

* * * * *

"I have seen pictures of a huge octopus pulling down a ship," said Carnes, "but I always fancied they were imaginary."

"They are. This monstrosity before us is no product of nature. A dozen of them would depopulate the seas in a year. It is a hideous parody of nature conceived in the brain of a madman and produced by some glandular disturbance. Saranoff spent years in glandular experimentation, and no doubt he has managed to stimulate the thyroid of a normal octopus and produce a giant. I fancy that the immediate parent of the thing before us was of normal size, and so, probably, are its brothers and sisters. The phenomenon of giantism of this nature occurs in alternate generations and then only in rare instances. Its grandparent may not be far away, however. I wish it was safe to use a submarine to explore that cavern."

"Why isn't it?"

"Any creature powerful enough to pull the _Arethusa_ under water would crush a frail submarine without effort. Anyway, a Navy sub isn't built for under-water exploration like this ball is. The window space is quite limited and they aren't equipped with powerful floodlights. I would like to be able to reach that thing and destroy it, but it can wait until later. The best thing we can do is to put out our lights and wait."

His hand sought the light switch, and the globe became dark. Only a tiny glimmer of light came down to them from the surface, a hundred fathoms above. In the darkness they stared into the depths of the sea.

* * * * *

For an hour they waited and then Dr. Bird grasped Carnes by the shoulder and pointed. Far in the distance could be seen a tiny point of light. It wavered and winked and at times disappeared, but it was gradually approaching them. Dr. Bird stepped to the telephone and the _Minneconsin_ moved a hundred yards further from the shore. The light disappeared again as though hidden by some opaque body. Their eyes had become accustomed to the dim light and they could dimly see a long snake-like body approach the globe and then suddenly withdraw.

The light appeared again only a few hundred yards away. The water swirled and the sphere swayed drunkenly as some gigantic body moved past it with express train speed and entered the mouth of the cavern. The light turned toward them and they could see the dim outlines of a small submarine on which it was mounted. Another rush of water came as the object which had entered the cave started to leave it, and the light swung around. It bore on a huge black body, and was reflected with a red glow from huge eyes, and the creature backed again into the cave. Back and forth across the mouth of the cavern the light played, and the watchers caught a glimpse of a huge parrot beak which could have engulfed a freight car. From the cavern projected twisting tentacles of gargantuan dimensions, and red eyes, thirty feet in diameter, glared balefully at them. For several minutes the light of the submarine played across the mouth of the cave, and then the floodlights on the cliff sprang into full glow and bathed the ball and the mouth of the tunnel in a flood of light.

Before their horrified gaze was an octopus of a size to make them disbelieve their eyes. The submarine had moved up to within a few feet of them, and the light from it played full on the ball. The submarine maneuvered in the vicinity, keeping the ball full in the beam of its light, and then drew back. As it did so, the floodlights on the cliff died out and the beam of the submarine's light was directed away from them. Dr. Bird jumped to the telephone.

"Head straight out to sea and full speed ahead!" he shouted. "Don't try to pull us in; tow us!"

* * * * *

The ball swayed as the _Minneconsin's_ mighty engines responded to his orders and the cliff wall disappeared.

"As long as they know we're here, we might as well announce our presence in good style," said the doctor grimly as he closed a switch and threw all of the sphere's huge lights into action. He had turned on the lights just in time, for even as he did so a mighty tentacle shot out of the darkness and wrapped itself around the ball. For a moment it clung there and then was withdrawn.

"The thing can't stand light," remarked the doctor as he threw off the switch. "That sub was herding it like a cow by the use of a light beam. As long as we are lighted up we are safe from attack."

"Then for God's sake turn on the lights!" cried Carnes.

"I want it to attack us," replied the doctor calmly. "We have no offensive weapons and only by meeting an attack can we harm the thing."

As he spoke there came a soft whisper of sound from the vitrilene walls and they were thrown from their feet by a sudden jerk. Dr. Bird stumbled to the switch and closed it, and the ball was flooded with light. Two arms were now on them but they were slowly withdrawn as the lights glared forth. The huge outlines of the beast could be seen as it followed them toward the surface. Its great eyes glared at them hungrily. The submarine was visible only as a speck of light in the distance.

* * * * *

The _Minneconsin's_ speed was picking up under the urge of her huge steam turbines, and the ball was nearing the surface. The sea was light enough now that they could see for quite a distance. The telephone bell jangled and Dr. Bird picked the receiver from its hook.

"Hello," he said. "What's that? You can? By all means, fire. Yes, indeed, we're well out of danger; we must be thirty or forty feet down. Watch the fun now," he went on to Carnes as he replaced the receiver. "The beast is showing above the surface and they're going to shell it."

They watched the surface and suddenly there came a flash of light followed by a dull boom of sound. The huge octopus suddenly sank below them, thrashing its arms about wildly.

"A hit!" shouted Dr. Bird into the telephone. "Get it again if it shows up. I want it to get good and mad."

He turned off the lights in the ball and the octopus attacked again. The shell had taught it caution and it kept well down, but three huge arms came up from the depths of the sea and wrapped themselves about the ball. The forward motion stopped for a moment, and then came a jerk that threw them down. The ball started to sink.

"Our cable has parted!" cried the doctor. "Turn on the lights!"

* * * * *

Carnes closed the switch. The ball was so covered with the huge tentacles that they could see nothing, but the light had its usual effect and they were released. The ball sank toward the bottom and they could see the huge cephalopod lying below watching them. Blood was flowing from a wound near one of its eyes where the _Minneconsin's_ shell had found its mark.

Toward the huge monster they sank until they lay on the bottom of the ocean and a few yards from it. In an instant the sea became opaque and they could see nothing.

"He has shot his ink!" cried the doctor. "Here comes the real attack. Strap yourself to the wall where you can reach one of the motor switches."

Through the darkness huge arms came out and wrapped themselves around the ball. The heavy vitrilene groaned under the enormous pressure which was applied, but it held. The ink was clearing slightly and they could see that the sphere was covered by the arms. The mass moved and the huge maw opened before them. The pipes projecting from the sides of the ball were buried in the creature's flesh.

"Good Lord, he's going to swallow us!" gasped the doctor. "Quick, Carnes, the motor switch."

He closed one of them as he spoke, and the powerful little electric motors began to hum, forcing forward the piston attached to the tank connected to the hollow rods. Steadily the little motors hummed, and the tank emptied through the rods into the body of the giant cephalopod.

"I hope the stuff works fast," groaned the doctor as they approached closer to the giant maw. "I never tried giving an octopus a hypodermic injection of prussic acid before, but it ought to do the business. There's enough acid there to kill half New York City."

* * * * *

Carnes blanched as the ball approached the mouth. One by one the arms unwound until only one was holding them and the jaws opened wider. They were almost in them when the motion stopped. They could feel a shudder run through the arm which held them. For a moment the arm alternately expanded and contracted, almost releasing them only to clutch them again. Another arm came from the depths and whipped about the ball, and again the vitrilene groaned at the pressure which was applied. The arms were suddenly withdrawn and the ball started to sink.

"Drop the lead, Carnes!" cried the doctor. With the aid of the detective he operated the electric catches which held the huge mass of lead to the bottom, and the sphere shot up through the water like a rocket. It leaped clear of the water and fell back with a splash. A half mile away the _Minneconsin_ was swinging in a wide circle to head back toward them. They turned their gaze toward the shore.

As they looked a giant arm shot a hundred yards up into the air, twisting and writhing frantically. It disappeared, and another, and then half a dozen flashed into the air. The arms dipped below the surface. A huge black body reared its bulk free from the water for a moment, and the sea boiled as though in a violent storm. The body sank and again the arms were thrown up, twisting and turning like a half dozen huge snakes. The whole creature sank below the waves and the ball tossed back and forth, often buried under tons of water and once tossed thirty feet into the air by the huge waves.

* * * * *

A momentary lull came in the waves. Carnes gave a cry of astonishment and pointed toward the shore. With an effort, Dr. Bird twisted himself in his lashing and looked in that direction. The huge body had again come to the surface, and three of the arms were towering into the air. Grasped in them was a long, black, cigar-shaped object. As they watched the object was torn into two parts and the fragments crushed by the enormous power of the octopus. Again the arms writhed in torment, and then they stiffened out. For a moment they towered in the air and then slowly sank below the surface of the sea.

"The cyanide has worked," cried the doctor, "and in its last agonies the creature has turned on its creator and destroyed him. It is a shame, for Saranoff was a brilliant although perverted genius, and besides, I would have liked to have learned his method. However, I may find something when we open the land end and raid the cave; and really, he was too brilliant a man to hang for murder. Once we open the cave and I get any data that is there, my connection with the case will end. Trailing down the gold and recovering it is a routine matter for Bolton, and one in which he won't need my help."

"What about that creature we saw in the cave, Doctor? Won't it hatch into another terror of the sea like the thing that destroyed the ship?"

"The trochosphere? No, I'm not worried there. It won't try to leave the cave for some days yet, and by that time we'll have the land end opened and the floodlights turned on. They will keep it there and it will starve to death. We could send down a sub to feed it a torpedo, but there's no need. Nature will dispose of it. Meanwhile, I hope the _Minneconsin_ rigs up a jury tackle pretty soon and takes us on board. I'm getting seasick."

Beneath the huge central arch in Cooper Square a meeting was in progress--a gathering of the gray-clad workers of the lower levels of New York. Less than two hundred of their number were in evidence, and these huddled in dejected groups around the pedestal from which a fiery-tongued orator was addressing them. Lounging negligently at the edge of the small crowd were a dozen of the red police.

"I tell you, comrades," the speaker was shouting, "the time has come when we must revolt. We must battle to the death with the wearers of the purple. Why work out our lives down here so they can live in the lap of luxury over our heads? Why labor day after day at the oxygen generators to give them the fresh air they breathe?"

The speaker paused uncertainly as a chorus of raucous laughter came to his ears. He glared belligerently at a group of newcomers who stood aloof from his own gathering. Seven or eight of them there were, and they wore the gray with obvious discomfort. Slummers! Well, they'd hear something they could carry back with them when they returned to their homes!

"Why," he continued in rising tones, "do we sit at the controls of the pneumatic tubes which carry thousands of our fellows to tasks equally irksome, while they of the purple ride their air yachts to the pleasure cities of the sky lanes? Never in the history of mankind have the poor been poorer and the rich richer!"

"Yah!" shouted a disrespectful voice from among the newcomers. "You're full o' bunk! Nothing but bunk!"

An ominous murmur swelled from the crowd and the red police roused from their lethargy. The mounting scream of a siren echoed in the vaulted recesses above and re-echoed from the surrounding columns--the call for reserves.

* * * * *

All was confusion in the Square. The little group of newcomers immediately became the center of a melee of dangerous proportions. Some of the more timid of the wearers of the gray struggled to get out of the crowd and away. Others, not in sympathy with the speaker, rushed to the support of the besieged visitors. The police were, for the moment, overwhelmed.

The orator, mad with resentment and injured pride, hurled himself into the group. A knife flashed in his hand; rose and fell. A scream of agony shrilled piercingly above the din of the fighting.

Then came the reserves, and the wielder of the knife turned to escape. He broke away from the milling combatants and made speedily for the shadows that lay beyond the great pillars of the Square. But he never reached them, for one of the red guards raised his riot pistol and fired. There was a dull _plop_, and a rubbery something struck the fleeing man and wrapped powerful tentacles around his body, binding him hand and foot in their swift embrace. He fell crashing to the pavement.

A lieutenant of the red police was shouting his orders and the din in the Square was deafening. With their numbers greatly augmented, the guards were now in control of the situation and their maces struck left and right. Groans and curses came from the gray-clad workers, who now fought desperately to escape.

Then, with startling suddenness, the artificial sunlight of the cavernous Square was gone, leaving the battle to continue in utter darkness.

* * * * *

Cooper Square, in the year 2108, was the one gathering place in New York City where the wearers of the gray denim were permitted to assemble and discuss their grievances publicly. Deep in the maze of lower-level ways seldom visited by wearers of the purple, the grottolike enclosure bore the name of a philanthropist of the late nineteenth century and still carried a musty air of certain of the traditions of that period.

In Astor Way, on the lowest level of all, there was a tiny book shop. Nestled between two of the great columns that provided foundation support for the eighty levels above, it was safely hidden from the gaze of curious passersby in the Square. Slumming parties from afar, their purple temporarily discarded for the gray, occasionally passed within a stone's throw of the little shop, never suspecting the existence of such a retreat amidst the dark shadows of the pillars. But to the initiated few amongst the wearers of the gray, and to certain of the red police, it was well known.

Rudolph Krassin, proprietor of the establishment, was a bent and withered ancient. His jacket of gray denim hung loosely from his spare frame and his hollow cough bespoke a deep-seated ailment. Looking out from behind thick lenses set in his square-rimmed spectacles, the watery eyes seemed vacant; uncomprehending. But old Rudolph was a scholar--keen-witted--and a gentleman besides. To his many friends of the gray-clad multitude he was an anomaly; they could not understand his devotion to his well-thumbed volumes. But they listened to his words of wisdom and, more frequently than they could afford, parted with precious labor tickets in exchange for reading matter that was usually of the lighter variety.

* * * * *

When the fighting started in the Square, Rudolph was watching and listening from a point of vantage in the shadows near his shop. This fellow Leontardo, who was the speaker, was an agitator of the worst sort. His arguments always were calculated to arouse the passions of his hearers; to inflame them against the wearers of the purple. He had nothing constructive to offer. Always he spoke of destruction; war; bloodshed. Rudolph marveled at the patience of the red police. To-day, these newcomers, obviously a slumming party of youngsters bent on whatever mischief they could find, were interfering with the speaker. The old man chuckled at the first interruption. But at signs of real trouble he scurried into the shadows and vanished in the blackness of first-level passages known only to himself. He knew where to find the automatic sub-station of the Power Syndicate.

Returning to the darkness he had created in the Square, he was relieved to find that the sounds of the fighting had subsided. Apparently most of the wearers of the gray had escaped. He skirted the avenue of pillars along Astor Way, feeling his way from one to another as he progressed toward his little shop. Peering into the blackness of the square he saw the feeble beams of several flash-lamps in the hands of the police. They were searching for survivors of the fracas, maces and riot pistols held ready for use. A sobbing gasp from close by set his pulses throbbing. He crept stealthily in the direction from which the sound had come.

"Steady now," came a whispered voice. "My uncle's shop is close by. He'll take you in. Here--let me lift you."

* * * * *

There was a shuffling on the opposite side of the pillar at which Rudolph had halted; another grunt of pain.

"Karl!" hissed the old man. It was his nephew.

"Uncle Rudolph?" came the guarded response.

"Yes. Can I help you?"

"Quick--yes--he's fainted."

The old man was around the huge base of the column in an instant. He groped in the darkness and his hands encountered human bodies.

"Who is it?" he breathed.

"One of the hecklers, Uncle. A young lad; and of the purple I think. He's been knifed."

Together they dragged the inert form into the shelter of the long line of pillars. There was a trampling of many men in the square. That would be a second detachment of reserves. A ray of light filtered through and dancing shadows of the giant columns made grotesque outlines against the walls of the Way. A portable searchlight had been brought to the scene. They must hurry.

Impeded by the dead weight of their burden, they made sorry progress and several times found it necessary to halt in the shadow of a pillar while the red police passed by in their search of the Square. It was with a sigh of relief that Rudolph opened the door of his shop and with still greater satisfaction closed and bolted it securely. His nephew shouldered the limp form of the unconscious youth and carried it to his own bed in one of the rear rooms.

"Ugh!" exclaimed old Rudolph as he ripped open the young man's shirt, "it's a nasty cut. Warm water, Karl."

The gaping wound was washed and bound tightly. Rudolph's experienced fingers told him the knife had not reached a vital spot. The youth would recover.

"But Karl," he objected, "he wears the purple. Under the gray. See! It'll get us in trouble if we keep him."

He was stripping the young man of his clothing to prepare him for bed. Suddenly there was revealed on the white skin a triangular mark. Bright scarlet it was and just over the right hip. He made a hasty attempt to hide it from the watching eyes of Karl.

"Uncle!" snapped his nephew, "--the mark you call cursed! He has it, too!"

* * * * *

The tall young man in gray was on his knees, tearing the hands of the old man away. He saw the mark clearly now. There was no further use of attempting to conceal it. Rudolph rose and faced his angered nephew, his watery eyes inscrutable.

"You told me, Rudolph, that it was a brand that cursed me. I have seen it on him, too. You have lied to me."

The old man's eyes wavered. He trembled violently.

"Why did you lie?" demanded Karl. "Am I not your nephew? Am I not really cursed as you've maintained? Tell me--tell me!"

He had the old man by the shoulders, shaking him cruelly.

"Karl--Karl," begged the helpless ancient, "it was for your good. I swear it. You were born to the purple. That's what that mark means--not that you're degraded to the gray, as I said. But there's a reason. Let me explain."

"Bah! A reason! You've kept me in this misery and squalor for a reason! Who's my father?"

He flung Rudolph to the floor, where the old man crouched in apprehensive misery.

"Please Karl--don't! I can explain. Just give me time. It's a long story."

"Time! Time! For twenty-odd years you've lied to me; cheated me. My birthright--where is it?"

He menaced his supposed uncle; was about to strike him. Then suddenly he was ashamed. He turned on his heel.

"I'm leaving," he said shortly.

"Karl--my boy," begged Rudolph Krassin, struggling to his feet. "You can't! That lad in there--he--"

But Karl was too angry to reason.

"To hell with him!" he raged, "and to hell with you! I'm through!"

He stamped from the room and out into the eery shadows of the Way. Karl was done with his old life. He'd go to the upper levels and claim his rights. Some day, too, he'd punish the man who'd stolen them away. God! Born to the purple! To think he'd missed it all! Probably was kidnaped by the old rascal he'd been calling uncle. But he'd find out. Rudolph didn't have to explain. Fingerprint records would clear his name; establish his rightful station in life. He dived into a passage that would lead him to one of the express lifts. He'd soon be overhead.

* * * * *

A sergeant of the red police looked up startled from his desk as a tall youth in the gray denim of forty levels below appeared before him.

"Well?" he growled. The stalwart young worker had stared belligerently and insolently, he thought.

"I want to check my fingerprint record, Sergeant."

"Hm. Pretty cocky, aren't you? The records for such as you are down below, where you belong."

"Not mine, I think."

"So? And who the devil are you?"

"That's what I'm here to find out. I've got a triangle branded on my right hip."

"A what?"

"Triangle. Here--look!"

The amazing youngster had raised his jacket and was pulling at his shirt. The sergeant stared at what was revealed, his eyes bulging as he looked.

"Lord!" he gasped, "a Van Dorn--in the gray!"

Quickly he turned to the radiovision and made rapid connection with several persons in turn--important ones, by the appearance of the features of each in the brilliant disc of the instrument.

Karl was confused by the sudden turn of things. The sergeant talked so rapidly he could not catch the sense of his words. And that name, Van Dorn, eluded him. He knew he had heard it before, in the little shop down there in Astor Way. But he could not place it. He wished fervently that he had paid more attention to the desires of old Rudolph; had studied more and read the books the old man had begged him to read. His new surroundings confused him, too, and he knew that he was the center of some great new excitement.

* * * * *

Then they were in the room; two individuals, one in the red uniform of a captain of police, the other a pompous, whiskered man in purple. Others followed and it seemed to Karl that the room was filled with them, strangers all, and they stared at him and chattered incessantly. He experienced an overwhelming impulse to run, but mastered it and faced them boldly.

A square of plate glass was placed under his outstretched fingers. It was smeared with something sticky and he watched the whiskered man as he held it up to the light and studied the impressions. Then there was more confusion. Everyone talked at once and the pompous one in purple made use of the radiovision, holding the square of glass near its disc for observation by the person he had called. The identification number was repeated aloud, a string of figures and letters that were a meaningless jumble to Karl. The room became quiet while the police captain thumbed the pages of a huge book he had taken from among many similar ones that filled a rack behind the desk.

Karl's blood froze in his veins at the rumbling swish of a car speeding through the pneumatic tube beneath their feet. His nerves were on edge. Then the captain of police looked up from the book and there was a peculiar glint in his eyes as he spoke.

"Peter Van Dorn. Missing since 2085. Wanted by Continental Government. Ha!"

The words came to Karl's ears through a growing sensation of unreality. It seemed that the speaker was miles away and that his voice and features were those of a radiovision likeness. Wanted by the great power across the Atlantic! It was unthinkable. Why, he had been but an infant in 2085! What possible crime could he have committed? But the red police captain was speaking again, this time in a chill voice. And the room of the police, thick with the smoke of a dozen cigars, became suddenly stifling.

"Where have you been these twenty-three years, Peter Van Dorn?" asked the captain. "Who have you lived with, I mean?"

* * * * *

Something warned him to protect old Rudolph. And somehow he wished he had not treated the old fellow as he did when he left. His self-possession returned. A wave of hot resentment swept over him.

"That's my affair," he said defiantly.

The captain shrugged his shoulders. "Oh, well," he said, "you needn't answer--now. We'll find out when it's necessary. In the meanwhile we'll have to turn you over to the Continental Ambassador."

Two of the red police advanced toward him and the rest drew back.

"You mean I'm under arrest?" asked Karl incredulously.

"Certainly. Of course you're not to be harmed."
