  The petty officer met his commander's gaze levelly. He smiled. "Yes, sir, I'm ready!" he said.

  "Good! It'll have to be quick work, though; I'll try and keep the sub pointed straight. Wait for the ray, then run like hell!"

  * * * * *

  The first officer took over the helm and Brown stepped to the forward ladder, waiting for the periodic ray to be discharged.

  The odd tingle came and vanished. "Now!" Wells roared, and Brown leaped down the thin steel rungs.

  He staggered at the bottom from the force of his impact, then straightened and raced madly forward. Through the drone of the motors the two officers could hear the staccato beat of his feet.

  But their eyes were glued to the teleview. Through clutching beds of seaweed the enemy submarine was ploughing. Her great, smooth bow lay straight ahead, metal hawser arm spanning the thirty feet between them. In another second, Keith thought grimly, two dynamite packed tubes of sudden death would thunderbolt into that hull, and--

  Brown pulled the lever.

  The tubes spat out compressed air; a scream ran through the submarine; and the two steel fish leaped from their sheaths, their tiny props roaring. Over the narrow gulf they shot; the range was short, their target dead ahead--and yet by bare inches they missed!

  No answering roar bellowed back. Keith had watched their course; had seen them flash by the enemy's bow, flicking it with their rudders, but nothing more. "Why?" he cried. And, as Bowman moved his hands in a hopeless gesture, he saw in the teleview the reason.

  It was a jagged pinnacle of rock, which, just before Brown had fired, had been straight ahead. The towing monster had seen it and veered sharply to avoid crashing. The barest change of course, yet sufficient to avoid the torpedoes....

  * * * * *

  Wells and Bowman were cursing savagely when the sound of Brown, racing desperately aft, jerked the commander to the ladder. He saw the petty officer at its foot. "Hurry!" Wells shouted. "The ray!"

  Brown grasped the steel rungs and scrambled upward, but he was too late. The fatal charge tingled. A peculiar, surprised expression washed over his face; his hands loosened their grip. For a second his eyes looked questioningly at his commander; a faint sigh escaped him; and then his arms flung out, his body relaxed, and he slumped like a slab of meat to the deck below....

  Keith Wells saw red. Blind to everything, he was just about to charge down the ladder to himself re-load the forward tubes when the grip of Hemmy Bowman's hand stayed him. The thing Hemmy was staring at in the teleview screen sobered him completely.

  The wall of rock to which the enemy submarine had first been charging had become visible, soaring vastly from the gloom of the sea-floor. And the monster was towing them straight into a dark, jagged cleft at its base.

  "It's a cavern!" Keith breathed. "A split in the rock--the lair of that devil. And we're being dragged into it!"

  CHAPTER III - Sacrifice

  At that moment Keith Wells knew fear. Each second they were being hauled closer to the monster's dim lair. It lay there, dark, mysterious, fingered by gently swaying, clammy kelp. A hushed solitude seemed to reign over it, aweing all undersea life from the vicinity.... Wells turned his head to meet Bowman's eyes, and read in them a silent question.

  What now?

  He groaned in the agony of his mind. In a few minutes, all would be over. Once the NX-1 was dragged into that dark cavern there'd be no chance of escaping to warn the world above, of saving the submarine. What now? The question brought beads of sweat to his tormented brow. He, Keith Wells, standing impotently by while his ship, the pride of the service, was hauled inch by inch to some strange doom!

  Racked by these thoughts, he murmured tortured, jerky phrases, unconscious he was giving voice to the things that flogged his brain.

  "What can I do? I've got to save my ship--I've got to get back to break the news--I've got to tell the world! But how? How--" His expression changed suddenly. "That's it! That hawser arm between us must be broken!"

  "Yes."

  First Officer Hemingway Bowman's clear voice broke in on the older man's thoughts with that one crisp word. Keith swung to find the other's eyes fixed levelly on his.

  "You're right, Keith. The hawser arm must be broken; with a depth charge, of course. It's the only way.

  "To attach a depth charge," he continued evenly, "a man must leave the ship. You can't, Keith. It will be me."

  * * * * *

  The commander did not speak. "I'll put on a sea-suit," Hemmy went on quickly, eyes lighting. "You tip the submarine and I'll slide out the conning tower exit port on the lee side, so they can't see me, and worm forward through the kelp. We're almost holding them even; that'll be easy. I'll be protected from the paralyzing shock until the last second, and it may not get me outside; that'll have to be chanced. The hawser arm's only some ten feet above the sea-floor; I can reach it with a hook on the charge." He paused.

  "I'll attach it; and when it bursts I'll try to get back and grab that ring on the midships exit port, and you can let me in when we get to the surface. But if I take too long, Keith--if I miss--you beat it without me. You understand? Beat it!"

  He gazed straight at his friend. "Understand, Keith?"

  Commander Keith Wells bowed his head in acquiescence. He was afraid that if he met Hemmy Bowman's steady eyes he'd make a fool of himself....

  Hemmy glanced at the screen once more, shivering as he saw how near the black cavern was. Then he moved rapidly, playing the cards carefully for his gamble with death. He had to: the trumps were in the other hand.

  From the locker where their sea-suits were stowed he grabbed his own, and with quick fingers ripped the slides and fitted it on. A sheath of yellow Lestofabrik, its weighted feet and gleaming casque transformed his slim figure into a giant such as might stalk through a nightmare. Built cunningly into the helmet was a tiny radio transmitter and receiver, with a range of a quarter-mile; hugging to the shoulders, inside nestled the air-making mechanism, its tiny generators already in motion. Around the helmet was fastened a small removable undersea-light. The wrists of the suit were very flexible, permitting the freest motion.

  Once in the suit, Hemmy smiled through the still-opened face-shield.

  "Got the depth charge ready, Keith? Make it fast--that cavern's near!... Good!"

  * * * * *

  Silently the commander fitted the black bomb to his friend's shoulders. It was timed to fire a minute after being set. A long wire hook craned from its top, and this hook Bowman would fasten on the hawser arm.

  "Without Sparks, I guess I'll have to communicate with you through portable," Keith said, and quickly donned one of the tiny portable sets.

  "Right. Ready, Keith."

  Bowman started his awkward, crawling progress up the ladder into the conning tower just above, Keith helping from behind. When they stood before the exit port on the lee side, Wells shot back its bolts and the door swung open, revealing the black emptiness of the water chamber. The commander gazed for a second into Bowman's eyes. The moment had come.

  Keith turned his head away, felt a hand grip his. He wrung it tightly....

  Bowman clumped into the chamber.

  The commander closed and locked the door, and he heard the streaming water pour in as Hemmy turned the valve. Then Wells sped down the ladder and tilted the diving and course rudders of the submarine.

  She swayed daintily over to port; held there. A moment later the recurring electric tingle brushed him. Had the enemy seen Bowman leave? Had the ray struck him down?

  He glared into the teleview. "Thank God!" he breathed. For Hemmy had already slid down the NX-1's smooth hull and was safe on the sea-floor beside her.

  "Everything right?" Wells asked, speaking into the microphone of his portable.

  "All O.K.," came the answer. "Going forward now. Kelp thick as hell."

  * * * * *

  Keith's eyes bored at the screen. This misshapen monster who was his friend! Almost obscured by bands of thick
-leaved kelp the yellow form moved, hands clearing a pathway through the weeds. Slowly but surely he made for the bow of the submersible.

  "Hard going, Keith. God--the cavern's right ahead!"

  It was ghostly to hear Hemmy's warm voice from the lifeless solitude outside. Breath coming quickly, Wells watched the silent scene--the cleft in the wall of rock overshadowing everything now. The diver fought ahead, gaining inch by inch.

  Now, save for occasional clumps of weed, he was exposed to the enemy.... Now the last desperate gauntlet was reached.... Keith felt his blood pound hotly.

  "I'm gaining, Keith. Gaining...."

  Bowman had little breath for speech. His tiny form battled on, now sinking from sight as he dropped into some masked gully, now wrestling slowly with great swaying strands of kelp, but always struggling ahead.

  "I'm at the bow, Keith! The hawser arm's right in our mooring holes. I'll go halfway before fastening the charge. Any signs of life from the devil?"

  "None yet, Hemmy. But go slow. Hide all you can, old man, for God's sake!..."

  Right beneath the metal arm, Bowman's dwarfed figure crept doggedly ahead. Forward, inch by breathless inch. Kelp thickened, washed away; the two hulking submersibles, captor and captive, surged onward--but just a little faster went the valiant figure with the black charge on its back.

  The towing monster had its snout in the cavern. The darkness thickened. Bowman was quarter way!

  He plunged desperately. Half way!

  "I'm there, Keith! Now for it!"

  "Oh, God!" Wells cried. "They see you; they're coming!"

  For he had seen strange shapes leaving the enemy submarine.

  And at that same moment, Bowman saw them, too.

  * * * * *

  They came like the blink of a dark eye from a door that had quickly slid open in the mysterious ship's bow. As tall as a man they were, and there were two of them, though at first the nature of their bodies merged with the wreathing kelp made them seem like a dozen. Bowman stared at them, hypnotized with fear. His legs and arms went dead, and his whole gallant spirit seemed to slump into lifeless clay. Now he knew why the fishermen had shrieked "machine-fish." Each one of them had eight tapering arms, eight restless tentacles. These were octopi, most hideous scavengers of the ocean floor! And not only octopi--but octopi sheathed in metal-scaled armor!

  As they came closer, he realized this preposterous fact. The dark substance of their writhing tentacles was not flesh: it was a coat of metal scales. And the fat central mass which held their eyes and vital organs and beaked jaw--this mass was completely enveloped by a globe of glass. From inside, he could see great eyes staring at him. The monsters came towards him quite slowly, obviously wary, advancing over the sea-floor in what was a hideous mockery of walking, their forward tentacles outstretched.

  With a sob, Hemmy Bowman pulled himself from his trance. He glanced back at the NX-1. He still had time to retreat. He might be able to get back inside before these monsters seized him.

  But that meant abandoning his job. And already his own submarine was nosing into the cavern. The choice between the octopi and retreat stared him in the face. He pulled himself together and jerked his arms back to action.

  * * * * *

  Eyes bulging, Keith Wells peered at the dim teleview screen. He saw the creatures approaching Hemmy. And then, suddenly, he remembered his radiophone.

  "Hemmy! Come back, for God's sake!" he cried. "Come back while you can--it's hopeless!"

  But Bowman had already seized the depth charge from his back and hooked it on the hawser arm above.

  Immediately, with that action, all caution fled from the approaching monsters. Their tentacles whipped furiously; and in a great arc they sprang for the tiny figure of the diver.

  With a deep breath, Hemmy staggered forward to meet them. "Keith!" he gasped. "I'll try to hold 'em away from the charge! When it bursts, zoom! Zoom like hell to the surface!" And then the tentacles had him.

  Keith watched, cursing his impotence to help. Hemmy had no weapon; he was trying to hold them back by the weight of his body; he reached out and grasped a tentacle and hugged it to him, shoving forward with all his puny strength. But all his effort was as nothing. One of the octopi writhed past him and darted onto the depth charge. Its tentacles tugged at the bomb; pulled furiously.

  The time charge exploded. The NX-1 rocked like a quivering reed; Wells was knocked violently to the floor; a vast roar smote his ear-drums. When he staggered to his feet he found that the octopus that was pulling at the charge had disappeared--blown into fragments of flesh and metal. But the hawser arm was broken! The NX-1, free, shot back a full fifty feet under the pull of her reversed screws. A cry echoed in her commander's ears:

  "Go back, Keith! Go like hell!"

  He saw the remaining octopus lift Bowman and whip to the exit port of its submarine. The lid slid into place, closing on the monster and his friend, and the enemy ship vanished into the black cavern....

  * * * * *

  Once clear of the opening, Keith set his motors full forward and brought the diving rudders up. Quickly the ship sped from the haunted sea-floor to the sun-warmed surface. A last thin call rang in his radiophone:

  "They've got me inside, Keith. It's dark, and filled with water. I can't see anything, but I--I guess we're going through the cavern.... Forget about me, old boy. So long! So--"

  The voice was abruptly cut off.

  Keith ripped the instrument from his head. Then, face white and drawn, he ran to the radio cubby. Standing over Sparks' inert body, he put through a call to Robert Knapp, on the Falcon.

  "Knapp?" he said harshly. "This is Wells. I'll be with you in a few minutes. Yes--yes--I'll tell you the whole story later. But get this now: Have the day shift all ready to take over the submarine by the time I pull alongside."

  He said no more just then; but rang off, and, looking back, he muttered savagely:

  "But I'll be back, Hemmy--I'll be back!"

  CHAPTER IV - In the Cavern

  "That's the story, Knapp. They got Bowman, and I had to run away. Their ship disappeared into the cavern. I've got a hunch, though, that it's not just a cavern, but a tunnel, leading through to some underwater world. That series of sub-sea earthquakes probably opened it up; and now these devil-octopi are free to pour out. I've got to find out what's what, and that's why I'm going down again as soon as the torpedo system's ready!"

  Keith and Robert Knapp were in the Falcon's chart room. On the table before them lay a broad white map with a cross-mark indicating the position of the mysterious dark cavern.

  Wells was striding up and down like a caged tiger in his impatience to be off. Every other minute he glared down to where the NX-1 lay alongside. On her conning tower stood the tall blond-haired figure of Graham, the first officer of the day shift, supervising the final details of the work of installing a system of jury controls whereby the submarine's torpedoes could be fired from her control room.

  Keith stopped short and faced Knapp. "It won't be so one-sided this time, Bob," he promised. "You see: when the location chart shows the enemy ship, I'll rush all men into the control room, where the paralyzing ray can't harm them. I don't know but what they have in other weapons, but I'm gambling on getting my torps in first. They've killed Bowman; they've ravaged a whole fishing fleet; they're free to emerge from their hole and maraud every ocean on the globe! They've got to be stopped! And since I'm armed and have the only submarine on the spot, I've got to do it! I know how to fight them now!"

  * * * * *

  Captain Robert Knapp's sense of things was badly disordered. He had just heard a story which his common sense told him couldn't be true, but which the evidence of his eyes had grimly authenticated. He had seen fifteen men slung aboard his ship from the NX-1's silent hull; men stretched in grotesque, limp attitudes; men struck down by a paralyzing ray. Why, no nation on earth had developed rays for warfare! Yet--a crew of helpless men was even then in the sick bay, receiving attention in
the hope that they might recover.

  "You're going right through that cavern, then, Wells?" he asked incredulously. "You're going to investigate what lies beyond?"

  "Nothing else! And I won't come out till I've blown that octopi ship to pieces!"

  "It sounds preposterous," Knapp murmured, shaking his head. "Octopi, you say--and clad in metal suits! Running a submarine more powerful than the NX-1! Armed with a ray--a paralyzing ray! I can't believe--I can't conceive--"

  "You've seen the men!... Knapp, if I were you I'd swing my eight-inchers out, bring up the plane catapult and keep the deck torpedo tubes loaded and ready. It's best to be prepared; God knows what's going on underseas these days!"
