For a time I think that we all had the same feeling. We did not want to do anything or to see anything. We just wanted to sit quiet and try to realize the wonder of it--that we should be resting in the plumb centre of one of the great oceans of the world. But soon the strange scene round us, illuminated in all directions by our lights, drew us to the windows.

We had settled upon a bed of high algae ('Cutleria multifida,' said Maracot), the yellow fronds of which waved around us, moved by some deep-sea current, exactly as branches would move in a summer breeze. They were not long enough to obscure our view, though their great flat leaves, deep golden in the light, flowed occasionally across our vision. Beyond them lay slopes of some blackish slag-like material which were dotted with lovely coloured creatures, holothurians, ascidians, echini and echinoderms, as thickly as ever an English spring time bank was sprinkled with hyacinths and primroses. These living flowers of the sea, vivid scarlet, rich purple and delicate pink, were spread in profusion upon that coal-black background. Here and there great sponges bristled out from the crevices of the dark rocks, and a few fish of the middle depths, themselves showing up as flashes of colour, shot across our circle of vivid radiance. We were gazing enraptured at the fairy scene when an anxious voice came down the tube:

'Well, how do you like the bottom? Is all well with you? Don't be too long, for the glass is dropping and I don't like the look of it. Giving you air enough? Anything more we can do?'

'All right, Captain!' cried Maracot, cheerily. 'We won't be long. You are nursing us well. We are quite as comfortable as in our own cabin. Stand by presently to move us slowly forwards.'

We had come into the region of the luminous fishes, and it amused us to turn out our own lights, and in the absolute pitch-darkness--a darkness in which a sensitive plate can be suspended for an hour without a trace even of the ultra-violet ray--to look out at the phosphorescent activity of the ocean. As against a black velvet curtain one saw little points of brilliant light moving steadily along as a liner at night might shed light through its long line of portholes. One terrifying creature had luminous teeth which gnashed in Biblical fashion in the outer darkness. Another had long golden antennae, and yet another a plume of flame above its head. As far as our vision carried, brilliant points flashed in the darkness, each little being bent upon its own business, and lighting up its own course as surely as the nightly taxicab at the theatre-hour in the Strand. Soon we had our own lights up again and the Doctor was making his observations of the sea-bottom.

'Deep as we are, we are not deep enough to get any of the characteristic Bathic deposits,' said he. 'These are entirely beyond our possible range. Perhaps on another occasion with a longer hawser-'

'Cut it out!' growled Bill. 'Forget it!'

Maracot smiled. 'You will soon get acclimatized to the depths, Scanlan. This will not be our only descent.'

'The Hell you say!' muttered Bill.

'You will think no more of it than of going down into the hold of the Stratford. You will observe, Mr. Headley, that the groundwork here, so far as we can observe it through the dense growth of hydrozoa and silicious sponges, is pumicestone and the black slag of basalt, pointing to ancient plutonic activities. Indeed, I am inclined to think that it confirms my previous view that this ridge is part of a volcanic formation and that the Maracot Deep,' he rolled out the words as if he loved them, 'represents the outer slope of the mountain. It has struck me that it would be an interesting experiment to move our cage slowly onwards until we come to the edge of the Deep, and see exactly what the formation may be at that point. I should expect to find a precipice of majestic dimensions extending downwards at a sharp angle into the extreme depths of the ocean.'

The experiment seemed to me to be a dangerous one, for who could say how far our thin hawser could bear the strain of lateral movement; but with Maracot danger, either to himself or to anyone else, simply did not exist when a scientific observation had to be made. I held my breath, and so I observed did Bill Scanlan, when a slow movement of our steel shell, brushing aside the waving fronds of seaweed, showed that the full strain was upon the line. It stood it nobly, however, and with a very gentle sweeping progression we began to glide over the bottom of the ocean, Maracot, with a compass in the hollow of his hand, shouting his direction as to the course to follow, and occasionally ordering the shell to be raised so as to avoid some obstacle in our path.

'This basaltic ridge can hardly be more than a mile across,' he explained. 'I had marked the abyss as being to the west of the point where we took our plunge. At this rate, we should certainly reach it in a very short time.'

We slid without any check over the volcanic plain, all feathered by the waving golden algae and made beautiful by the gorgeous jewels of Nature's cutting, flaming out from their setting of jet. Suddenly the Doctor dashed to the telephone.

'Stop her!' he cried. 'We are there!'

A monstrous gap had opened suddenly before us. It was a fearsome place, the vision of a nightmare. Black shining cliffs of basalt fell sheer down into the unknown. Their edges were fringed with dangling laminaria as ferns might overhang some earthly gorge, but beneath that tossing, vibrating rim there were only the black gleaming walls of the chasm. The rocky edge curved away from us, but the abyss might be of any breadth, for our lights failed to penetrate the gloom which lay before us. When a Lucas signalling lamp was turned downwards it shot out a long golden lane of parallel beams extending down, down, down until it was quenched in the gloom of the terrible chasm beneath us.

'It is indeed wonderful!' cried Maracot, gazing out with a pleased proprietary expression upon his thin, eager face. 'For depth I need not say that it has often been exceeded. There is the Challenger Deep of twenty-six thousand feet near the Ladrone Islands, the Planet Deep of thirty-two thousand feet off the Philippines, and many others, but it is probable that the Maracot Deep stands alone in the declivity of its descent, and is remarkable also for its escape from the observation of so many hydrographic explorers who have charted the Atlantic. It can hardly be doubted-'

He had stopped in the middle of a sentence and a look of intense interest and surprise had frozen upon his face. Bill Scanlan and I, gazing over his shoulders, were petrified by that which met our startled eyes.

Some great creature was coming up the tunnel of light which we had projected into the abyss. Far down where it tailed off into the darkness of the pit we could dimly see the vague black lurchings and heavings of some monstrous body in slow upward progression. Paddling in clumsy fashion, it was rising with dim flickerings to the edge of the gulf. Now, as it came nearer, it was right in the beam, and we could see its dreadful form more clearly. It was a beast unknown to Science, and yet with an analogy to much with which we are familiar. Too long for a huge crab and too short for a giant lobster, it was moulded more upon the lines of the crayfish, with two monstrous nippers outstretched on either side, and a pair of sixteen-foot antennae which quivered in front of its black dull sullen eyes. The carapace, light yellow in colour, may have been ten feet across, and its total length, apart from the antennae, must have been not less than thirty.

'Wonderful!' cried Maracot, scribbling desperately in his notebook. 'Semi-pediculated eyes, elastic lamellae, family crustacea, species unknown. Crustaceus Maracoti--why not? Why not?'

'By gosh, I'll pass its name, but it seems to me it's coming our way!' cried Bill. 'Say, Doc, what about putting our light out?'

'Just one moment while I note the reticulations!' cried the naturalist. 'Yes, yes, that will do.' He clicked off the switch and we were back in our inky darkness, with only the darting lights outside like meteors on a moonless night.

'That beast is sure the world's worst,' said Bill, wiping his forehead. 'I felt like the morning after a bottle of Prohibition Hoosh.'

'It is certainly terrible to look at,' Maracot remarked, 'and perhaps terrible to deal with also if we were really exposed to those monstrous claws. But inside our steel case we can afford to examine him in safety and at our ease.'

He had hardly spoken when there came a rap as from a pickaxe upon our outer wall. Then there was a long drawn rasping and scratching, ending in another sharp rap.

'Say, he wants to come in!' cried Bill Scanlan in alarm. 'By gosh! we want "No Admission" painted on this shack.' His shaking voice showed how forced was his merriment, and I confess that my own knees were knocking together as I was aware of the stealthy monster closing up with an even blacker darkness each of our windows in succession, as he explored this strange shell which, could he but crack it, might contain his food.

'He can't hurt us,' said Maracot, but there was less assurance in his tone. 'Maybe it would be as well to shake the brute off.' He hailed the Captain up the tube.

'Pull us up twenty or thirty feet,' he cried.

A few seconds later we rose from the lava plain and swung gently in the still water. But the terrible beast was pertinacious. After a very short interval we heard once more the raspings of his feelers and the sharp tappings of his claws as he felt us round. It was terrible to sit silently in the dark and know that death was so near. If that mighty claw fell upon the window, would it stand the strain? That was the unspoken question in each of our minds.

But suddenly an unexpected and more urgent danger presented itself. The tappings had gone to the roof of our little dwelling, and now we began to sway with a rhythmic movement to and fro.

'Good God!' I cried. 'It has hold of the hawser. It will surely snap it.'

'Say, Doc, it's mine for the surface. I guess we've seen what we came to see, and it's home, sweet home for Bill Scanlan. Ring up the elevator and get her going.'

'But our work is not half done,' croaked Maracot. 'We have only begun to explore the edges of the Deep. Let us at least see how broad it is. When we have reached the other side I shall be content to return.' Then up the tube: 'All well, Captain. Move on at two knots until I call for a stop.'

We moved slowly out over the edge of the abyss. Since darkness had not saved us from attack we now turned on our lights. One of the portholes was entirely obscured by what appeared to be the creature's lower stomach. Its head and its great nippers were at work above us, and we still swayed like a clanging bell. The strength of the beast must have been enormous. Were ever mortals placed in such a situation, with five miles of water beneath--and that deadly monster above? The oscillations became more and more violent. An excited shout came down the tube from the Captain as he became aware of the jerks upon the hawser, and Maracot sprang to his feet with his hands thrown upwards in despair. Even within the shell we were aware of the jar of the broken wires, and an instant later we were falling into the mighty gulf beneath us.

As I look back at that awful moment I can remember hearing a wild cry from Maracot.

'The hawser has parted! You can do nothing! We are all dead men!' he yelled, grabbing at the telephone tube, and then, 'Good-bye, Captain, good-bye to all.' They were our last words to the world of men.

We did not fall swiftly down, as you might have imagined. In spite of our weight our hollow shell gave us some sustaining buoyancy, and we sank slowly and gently into the abyss. I heard the long scrape as we slid through the claws of the horrible creature who had been our ruin, and then with a smooth gyration we went circling downwards into the abysmal depths. It may have been fully five minutes, and it seemed like an hour, before we reached the limit of our telephone wire and snapped it like a thread. Our air tube broke off at almost the same moment and the salt water came spouting through the vents. With quick, deft hands Bill Scanlan tied cords round each of the rubber tubes and so stopped the inrush, while the Doctor released the top of our compressed air which came hissing forth from the tubes. The lights had gone out when the wire snapped, but even in the dark the Doctor was able to connect up the Hellesens dry cells which lit a number of lamps in the roof.

'It should last us a week,' he said, with a wry smile. 'We shall at least have light to die in.' Then he shook his head sadly and a kindly smile came over his gaunt features. 'It is all right for me. I am an old man and have done my work in the world. My one regret is that I should have allowed you two young fellows to come with me. I should have taken the risk alone.'

I simply shook his hand in reassurance, for indeed there was nothing I could say. Bill Scanlan, too, was silent. Slowly we sank, marking our pace by the dark fish shadows which flitted past our windows. It seemed as if they were flying upwards rather than that we were sinking down. We still oscillated, and there was nothing so far as I could see to prevent us from falling on our side, or even turning upside down. Our weight, however, was, fortunately, very evenly balanced and we kept a level floor. Glancing up at the bathymeter I saw that we had already reached the depth of a mile.

'You see, it is as I said,' remarked Maracot, with some complacency. 'You may have seen my paper in the Proceedings of the Oceanographical Society upon the relation of pressure and depth. I wish I could get one word back to the world, if only to confute Bulow of Giessen, who ventured to contradict me.'

'My gosh! If I could get a word back to the world I wouldn't waste it on a square-head highbrow,' said the mechanic. 'There is a little wren in Philadelphia that will have tears in her pretty eyes when she hears that Bill Scanlan has passed out. Well, it sure does seem a darned queer way of doing it, anyhow.'

'You should never have come,' I said, putting my hand on his.

'What sort of tin-horn sport should I have been if I had quitted?' he answered. 'No, it's my job, and I am glad I stuck it.'

'How long have we?' I asked the Doctor, after a pause.

He shrugged his shoulders.

'We shall have time to see the real bottom of the ocean, anyhow,' said he. 'There is air enough in our tubes for the best part of a day. Our trouble is with the waste products. That is what is going to choke us. If we could get rid of our carbon dioxide-'

'That I can see is impossible.'

'There is one tube of pure oxygen. I put it in in case of accidents. A little of that from time to time will help to keep us alive. You will observe that we are now more than two miles deep.'

'Why should we try to keep ourselves alive? The sooner it is over the better,' said I.

'That's the dope,' cried Scanlan. 'Cut loose and have done with it.' .

'And miss the most wonderful sight that man's eye has ever seen!' said Maracot. 'It would be treason to Science. Let us record facts to the end, even if they should be for ever buried with our bodies. Play the game out.'

'Some sport, the Doc!' cried Scanlan. 'I guess he has the best guts of the bunch. Let us see the spiel to an end.'

We sat patiently on the settee, the three of us, gripping the edges of it with strained fingers as it swayed and rocked, while the fishes still flashed swiftly upwards athwart the portholes.

'It is now three miles,' remarked Maracot. 'I will turn on the oxygen, Mr. Headley, for it is certainly very close. There is one thing,' he added, with his dry, cackling laugh, 'it will certainly be the Maracot Deep from this time onwards. When Captain Howie takes back the news my colleagues will see to it that my grave is also my monument. Even Bulow of Giessen-' He babbled on about some unintelligible scientific grievance.

We sat in silence again, watching the needle as it crawled on to its fourth mile. At one point we struck something heavy, which shook us so violently that I feared that we would turn upon our side. It may have been a huge fish, or conceivably we may have bumped upon some projection of the cliff over the edge of which we had been precipitated. That edge had seemed to us at the time to be such a wondrous depth, and now looking back at it from our dreadful abyss it might almost have been the surface. Still we swirled and circled lower and lower through the dark green waste of waters. Twenty-five thousand feet now was registered upon the dial.

'We are nearly at our journey's end,' said Maracot. 'My Scott's recorder gave me twenty-six thousand seven hundred last year at the deepest point. We shall know our fate within a few minutes. It may be that the shock will crush us. It may be--'

And at that moment we landed.

There was never a babe lowered by its mother on to a feather-bed who nestled down more gently than we on to the extreme bottom of the Atlantic Ocean. The soft thick elastic ooze upon which we lit was a perfect buffer, which saved us from the slightest jar. We hardly moved upon our seats, and it is as well that we did not, for we had perched upon some sort of a projecting hummock, clothed thickly with the viscous gelatinous mud, and there we were balanced rocking gently with nearly half our base projecting and unsupported. There was a danger that we would tip over on our side, but finally we steadied down and remained motionless. As we did so Dr. Maracot, staring out through his porthole, gave a cry of surprise and hurriedly turned out our electric light.

To our amazement we could still see clearly. There was a dim, misty light outside which streamed through our porthole, like the cold radiance of a winter morning. We looked out at the strange scene, and with no help from our own lights we could see clearly for some hundred yards in each direction. It was impossible, inconceivable, but none the less the evidence of our senses told us that it was a fact. The great ocean floor is luminous.

'Why not?' cried Maracot, when we had stood for a minute or two in silent wonder. 'Should I not have foreseen it? What is this pteropod or globigerina ooze? Is it not the product of decay, the mouldering bodies of a billion billion organic creatures? And is decay not associated with phosphorescent luminosity? Where, in all creation, would it be seen if it were not here? Ah! It is indeed hard that we should have such a demonstration and be unable to send our knowledge back to the world.'

'And yet,' I remarked, 'we have scooped half a ton of radiolarian jelly at a time and detected no such radiance.'

'It would lose it, doubtless, in its long journey to the surface. And what is half a ton compared to these far-stretching plains of slow putrescence? And see, see,' he cried in uncontrollable excitement, 'the deep-sea creatures graze upon this organic carpet even as our herds on land graze upon the meadows!'

As he spoke a flock of big black fish, heavy and squat, came slowly over the ocean bed towards us, nuzzling among the spongy growths and nibbling away as they advanced. Another huge red creature, like a foolish cow of the ocean, was chewing the cud in front of my porthole, and others were grazing here and there, raising their heads from, time to time to gaze at this strange object which had so suddenly appeared among them.

I could only marvel at Maracot, who in that foul atmosphere, seated under the very shadow of death, still obeyed the call of Science and scribbled his observations in his notebook. Without following his precise methods, I none the less made my own mental notes, which will remain for ever as a picture stamped upon my brain. The lowest plains of ocean consist of red clay, but here it was overlaid by the grey bathybian slime which formed an undulating plain as far as our eyes could reach. This plain was not smooth, but was broken by numerous strange rounded hillocks like that upon which we had perched, all glimmering in the spectral light. Between these little hills there darted great clouds of strange fish, many of them quite unknown to Science, exhibiting every shade of colour, but black and red predominating. Maracot watched them with suppressed excitement and chronicled them in his notes.

The air had become very foul, and again we were only able to save ourselves by a fresh emission of oxygen. Curiously enough, we were all hungry--I should rather say ravenous--and we fell upon the potted beef with bread and butter, washed down by whisky and water, which the foresight of Maracot had provided. With my perceptions stimulated by this refreshment, I was seated at my lookout portal and longing for a last cigarette, when my eyes caught something which sent a whirl of strange thoughts and anticipations through my mind.

I have said that the undulating grey plain on every side of us was studded with what seemed like hummocks. A particularly large one was in front of my porthole, and I looked out at it within a range of thirty feet. There was some peculiar mark upon the side of it, and as I glanced along I saw to my surprise that this mark was repeated again and again until it was lost round the curve. When one is so near death it takes much to give one a thrill about anything connected with this world, but my breath failed me for a moment and my heart stood still as I suddenly realized that it was a frieze at which I was looking and that, barnacled and worn as it was, the hand of man had surely at some time carved these faded figures. Maracot and Scanlan crowded to my porthole and gazed out in utter amazement at these signs of the omnipresent energies of man.

'It is carving, for sure!' cried Scanlan. 'I guess this dump has been the roof of a building. Then these other ones are buildings also. Say, boss, we've dropped plumb on to a regular burg.'

'It is, indeed, an ancient city,' said Maracot. 'Geology teaches that the seas have once been continents and the continents seas, but I have always distrusted the idea that in times so recent as the quaternary there could have been an Atlantic subsidence. Plato's report of Egyptian gossip had then a foundation of fact. These volcanic formations confirm the view that this subsidence was due to seismic activity.'

'There is regularity about these domes,' I remarked. 'I begin to think that they are not separate houses, but that they are cupolas and form the ornaments of the roof of some huge building.'

'I guess you are right,' said Scanlan. 'There are four big ones at the corners and the small ones in lines between. It's some building, if we could see the whole of it! You could put the whole Merribank plant inside it--and then some.'

'It has been buried up to the roof by the constant dropping from above,' said Maracot. 'On the other hand, it has not decayed. We have a constant temperature of a little over 32° Fahrenheit in the great depths, which would arrest destructive processes. Even the dissolution of the Bathic remains which pave the floor of the ocean and incidentally give us this luminosity must be a very slow one. But, dear me! this marking is not a frieze but an inscription.'

There was no doubt that he was right. The same symbol recurred every here and there. These marks were unquestionably letters of some archaic alphabet.

'I have made a study of Phoenician antiquities, and there is certainly something suggestive and familiar in these characters,' said our leader. 'Well, we have seen a buried city of ancient days, my friends, and we carry a wonderful piece of knowledge with us to the grave. There is no more to be learned. Our book of knowledge is closed. I agree with you that the sooner the end comes the better.'

It could not now be long delayed. The air was stagnant and dreadful. So heavy was it with carbon products that the oxygen could hardly force its way out against the pressure. By standing on the settee one was able to get a gulp of purer air, but the mephitic reek was slowly rising. Dr. Maracot folded his arms with an air of resignation and sank his head upon his breast. Scanlan was now overpowered by the fumes and was already sprawling upon the floor. My own head was swimming, and I felt an intolerable weight at my chest. I closed my eyes and my senses were rapidly slipping away. Then I opened them for one last glimpse of that world which I was leaving, and as I did so I staggered to my feet with a hoarse scream of amazement.

A human face was looking in at us through the porthole!

Was it my delirium? I clutched at the shoulder of Maracot and shook him violently. He sat up and stared, wonder-struck and speechless at this apparition. If he saw it as well as I, it was no figment of the brain. The face was long and thin, dark in complexion, with a short, pointed beard, and two vivid eyes darting here and there in quick, questioning glances which took in every detail of our situation. The utmost amazement was visible upon the man's face. Our lights were now full on, and it must indeed have been a strange and vivid picture which presented itself to his gaze in that tiny chamber of death, where one man lay senseless and two others glared out at him with the twisted, contorted features of dying men, cyanosed by incipient asphyxiation. We both had our hands to our throats, and our heaving chests carried their message of despair. The man gave a wave of his hand and hurried away.

'He has deserted us!' cried Maracot.

'Or gone for help. Let us get Scanlan on the couch. It's death for him down there.'

We dragged the mechanic on to the settee and propped his head against the cushions. His face was grey and he murmured in delirium, but his pulse was still perceptible.

'There is hope for us yet,' I croaked.

'But it is madness!' cried Maracot. 'How can man live at the bottom of the ocean? How can he breathe? It is collective hallucination. My young friend, we are going mad.'

Looking out at the bleak, lonely grey landscape in the dreary spectral light, I felt that it might be as Maracot said. Then suddenly I was aware of movement. Shadows were flitting through the distant water. They hardened and thickened into moving figures. A crowd of people were hurrying across the ocean bed in our direction. An instant later they had assembled in front of the porthole and were pointing and gesticulating in animated debate. There were several women in the crowd, but the greater part were men, one of whom, a powerful figure with a very large head and a full black beard, was clearly a person of authority. He made a swift inspection of our steel shell, and, since the edge of our base projected over the place on which we rested, he was able to see that there was a hinged trap-door at the bottom. He now sent a messenger flying back, while he made energetic and commanding signs to us to open the door from within.

'Why not?' I asked. 'We may as well be drowned as be smothered. I can stand it no longer.'

'We may not be drowned,' said Maracot. 'The water entering from below cannot rise above the level of the compressed air. Give Scanlan some brandy. He must make an effort, if it is his last one.'

I forced a drink down the mechanic's throat. He gulped and looked round him with wondering eyes. Between us we got him erect on the settee and stood on either side of him. He was still half-dazed, but in a few words I explained the situation.

'There is a chance of chlorine poisoning if the water reaches the batteries,' said Maracot. 'Open every air tube, for the more pressure we can get the less water may enter. Now help me while I pull upon the lever.'

We bent our weight upon it and yanked up the circular plate from the bottom of our little home, though I felt like a suicide as I did so. The green water, sparkling and gleaming under our light, came gurgling and surging in. It rose rapidly to our feet, to our knees, to our waists, and there it stopped. But the pressure of the air was intolerable. Our heads buzzed and the drums of our ears were bursting. We could not have lived in such an atmosphere for long. Only by clutching at the rack could we save ourselves from falling back into the waters beneath us.

From our higher position we could no longer see through the portholes, nor could we imagine what steps were being taken for our deliverance. Indeed, that any effective help could come to us seemed beyond the power of thought, and yet there was a commanding and purposeful air about these people, and especially about that squat bearded chieftain, which inspired vague hopes. Suddenly we were aware of his face looking up at us through the water beneath and an instant later he had passed through the circular opening and had clambered on to the settee, so that he was standing by our side--a short sturdy figure, not higher than my shoulder, but surveying us with large brown eyes, which were full of a half-amused confidence, as who should say, 'You poor devils; you think you are in a very bad way, but I can clearly see the road out.'

Only now was I aware of a very amazing thing. The man, if indeed he was of the same humanity as ourselves, had a transparent envelope all round him which enveloped his head and body, while his arms and legs were free. So translucent was it that no one could detect it in the water, but now that he was in the air beside us it glistened like silver, though it remained as clear as the finest glass. On either shoulder he had a curious rounded projection beneath the clear protective sheath. It looked like an oblong box pierced with many holes, and gave him an appearance as if he were wearing epaulettes.

When our new friend had joined us another face appeared in the aperture of the bottom and thrust through it what seemed like a great bubble of glass. Three of these in succession were passed in and floated upon the surface of the water. Then six small boxes were handed up and our new acquaintance tied one with the straps attached to them to each of our shoulders, whence they stood up like his own. Already I began to surmise that no infraction of natural law was involved in the life of these strange people, and that while one box in some new fashion was a producer of air the other was an absorber of waste products. He now passed the transparent suits over our heads, and we felt that they clasped us tightly in the upper arm and waist by elastic bands, so that no water could penetrate. Within we breathed with perfect ease, and it was a joy to me to see Maracot looking out at me with his eyes twinkling as of old behind his glasses, while Bill Scanlan's grin assured me that the life-giving oxygen had done its work, and that he was his cheerful self once more. Our rescuer looked from one to another of us with grave satisfaction, and then motioned to us to follow him through the trap-door and out on to the floor of the ocean. A dozen willing hands were outstretched to pull us through and to sustain our first faltering steps as we staggered with our feet deep in the slimy ooze.

Even now I cannot get past the marvel of it! There we were, the three of us, unhurt and at our ease at the bottom of a five-mile abyss of water. Where was that terrific pressure which had exercised the imagination of so many scientists? We were no more affected by it than were the dainty fish which swam around us. It is true that, so far as our bodies were concerned, we were protected by these delicate bells of vitrine, which were in truth tougher than the strongest steel, but even our limbs, which were exposed, felt no more than a firm constriction from the water which one learned in time to disregard. It was wonderful to stand together and to look back at the shell from which we had emerged. We had left the batteries at work, and it was a wondrous object with its streams of yellow light flooding out from each side, while clouds of fishes gathered at each window. As we watched it the leader took Maracot by the hand, and we followed them both across the watery morass, clumping heavily through the sticky surface.

And now a most surprising incident occurred, which was clearly as astonishing to these strange new companions of ours as to ourselves. Above our heads there appeared a small, dark object, descending from the darkness above us and swinging down until it reached the bed of the ocean within a very short distance from where we stood. It was, of course, the deep-sea lead from the Stratford above us, making a sounding of that watery gulf with which the name of the expedition was to be associated. We had seen it already upon its downward path, and we could well understand that the tragedy of our disappearance had suspended the operation, but that after a pause it had been concluded, with little thought that it would finish almost at our feet. They were unconscious, apparently, that they had touched bottom, for the lead lay motionless in the ooze. Above me stretched the taut piano wire which connected me through five miles of water with the deck of our vessel. Oh, that it were possible to write a note and to attach it! The idea was absurd, and yet could I not send some message which would show them that we were still conscious? My coat was covered by my glass bell and the pockets were unapproachable, but I was free below the waist and my handkerchief chanced to be in my trousers pocket. I pulled it out and tied it above the top of the lead. The weight at once disengaged itself by its automatic mechanism, and presently I saw my white wisp of linen flying upwards to that world which I may never see again. Our new acquaintances examined the seventy-five pounds of lead with great interest, and finally carried it off with us as we went upon our way.

We had only walked a couple of hundred yards, threading our way among the hummocks, when we halted before a small square-cut door with solid pillars on either side and an inscription across the lintel. It was open, and we passed through it into a large, bare chamber. There was a sliding partition worked by a crank from within, and this was drawn across behind us. We could, of course, hear nothing in our glass helmets, but after standing a few minutes we were aware that a powerful pump must be at work, for we saw the level of the water sinking rapidly above us. In less than a quarter of an hour we were standing upon a sloppy stone-flagged pavement, while our new friends were busy in undoing the fastenings of our transparent suits. An instant later there we stood, breathing perfectly pure air in a warm, well-lighted atmosphere, while the dark people of the abyss, smiling and chattering, crowded round us with hand-shakings and friendly pattings. It was a strange, rasping tongue that they spoke, and no word of it was intelligible to us, but the smile on the face and the light of friendship in the eye are understandable even in the waters under the earth. The glass suits were hung on numbered pegs upon the wall, and the kindly folk half led and half pushed us to an inner door which opened on to a long downward-sloping corridor. When it closed again behind us there was nothing to remind us of the stupendous fact that we were the involuntary guests of an unknown race at the bottom of the Atlantic ocean and cut off for ever from the world to which we belonged.

Now that the terrific strain had been so suddenly eased we were all exhausted. Even Bill Scanlan, who was a pocket Hercules, dragged his feet along the floor, while Maracot and I were only too glad to lean heavily upon our guides. Yet, weary as I was, I took in every detail as we passed. That the air came from some air-making machine was very evident, for it issued in puffs from circular openings in the walls. The light was diffused and was clearly an extension of that fluor system which was already engaging the attention of our European engineers when the filament and lamp were dispensed with. It shone from long cylinders of clear glass which were suspended along the cornices of the passages. So much I had observed when our descent was checked and we were ushered into a large sitting-room, thickly carpeted and well furnished with gilded chairs and sloping sofas which brought back vague memories of Egyptian tombs. The crowd had been dismissed and only the bearded man with two attendants remained. 'Manda' he repeated several times, tapping himself upon the chest. Then he pointed to each of us in turn and repeated the words Maracot, Headley and Scanlan until he had them perfect. He then motioned us to be seated and said a word to one of the attendants, who left the room and returned presently, escorting a very ancient gentleman, white-haired and long-bearded, with a curious conical cap of black cloth upon his head. I should have said that all these folk were dressed in coloured tunics, which extended to their knees, with high boots of fish skin or shagreen. The venerable newcomer was clearly a physician, for he examined each of us in turn, placing his hand upon our brows and closing his own eyes as if receiving a mental impression as to our condition. Apparently he was by no means satisfied, for he shook his head and said a few grave words to Manda. The latter at once sent the attendant out once more, and he brought in a tray of eatables and a flask of wine, which were laid before us. We were too weary to ask ourselves what they were, but we felt the better for the meal. We were then led to another room, where three beds had been prepared, and on one of these I flung myself down. I have a dim recollection of Bill Scanlan coming across and sitting beside me.

'Say, Bo, that jolt of brandy saved my life,' said he. 'But where are we, anyhow?'

'I know no more than you do.'

'Well, I am ready to hit the hay,' he said, sleepily, as he turned to his bed. 'Say, that wine was fine. Thank God, Volstead never got down here.' They were the last words I heard as I sank into the most profound sleep that I can ever recall.
