Chapter Twenty One.Mildmay’s Adventure with an Octopus.The two succeeding days were very fully occupied upon the somewhat difficult and delicate task of effecting an equal division of the fabulously rich haul of rubies that they had so easily acquired in so short a time; and on the third day—being Sunday—everybody took a rest, as was usual with them whenever possible.But on the following Monday morning, after breakfast, theFlying Fishrose into the air, and, moving out to sea, proceeded to the reef upon which the unknown ship had been wrecked. It was determined to examine first what was believed to be the after part of the wreck; for if any documents, from the contents of which the ship could be identified, still existed in decipherable condition, it would be in one of the cabins that they would almost certainly be found. The position of this portion of the wreck, therefore, having been found, theFlying Fishwas sunk as close as possible to it, settling down upon a smooth, firm, sandy bottom, in fourteen fathoms of water, on the seaward side of the reef. There were but four male diving-suits in the ship, but Lethbridge and the Russian colonel were so very nearly alike in size and build that there was no doubt that the suit of the former would fit the latter; and Lethbridge therefore offered Sziszkinski the opportunity to experience the sensation of walking about on the ocean’s bed, and beholding anything of a novel character that there might be to see—an offer which the Russian had gladly accepted. A diving-suit had been provided for Lady Olivia, but it was deemed unadvisable that she should make her first essay at submarine exploration until the others had first been out, and had thus ascertained what difficulties and possible dangers were likely to be experienced. The four men who were going out—that is to say, Sir Reginald, Mildmay, von Schalckenberg, and Sziszkinski—accordingly descended to the lowermost depths of the ship, and entered the diving-room, leaving Lethbridge to entertain the two ladies and little Ida by pointing out such objects of interest as were to be seen from the tightly closed windows of the saloon.Going at once to the cupboard labelled with Colonel Lethbridge’s name, the professor drew forth the diving-dress and very handsome suit of diving-armour which it contained, and instructed his Russian friend how to don first the dress and then the armour, Sir Reginald and Mildmay meanwhile leisurely assuming their own proper suits; and when at length Sziszkinski was completely equipped, von Schalckenberg quickly donned his own suit, after which the quartette left the diving-room and entered what they called the chamber of egress, carefully closing and securing the door behind them. The water-tap was then turned on, and the chamber gradually filled with water, which flowed in at the level of the floor, and steadily rose about the four occupants until it was over their heads and had reached to the ceiling. Then, having first ascertained that everybody felt all right and quite comfortable, the professor opened the trap-door in the ship’s bottom, and the four men walked out over the flap and found themselves treading the sandy floor of the ocean upon which the ship rested.They were now in the tunnel-like passage formed by the starboard bilge-keel and the ship’s hull, which curved out over them vast and ponderous as an overhanging cliff. It was intensely dark here, though at either extremity of the tunnel could be seen a small patch of sombre green light, and they therefore switched on the electric lamps, which were attached,oneto the helmet and one to the belt of each man; and thus aided, they were enabled without difficulty to make their way out to what Mildmay called the daylight.Once there—that is to say, clear of the gloom of the overshadowing hull of theFlying Fish—they were able to see with tolerable distinctness, even without the assistance of their lamps, the depth of water being too great for the surface disturbance to reach the bottom and stir up the sand. The water, therefore, was clear and transparent, allowing the light of the sun, already high in the heavens, to pass through and somewhat dimly illuminate the ground upon which they walked with a soft, greenish-blue light. The water was alive with fish, darting restlessly hither and thither; and while some were evidently much alarmed at the apparition of the four gleaming armour-clad figures, from whom they retreated precipitately, others were as evidently consumed with curiosity as to what they were, and came swimming about them with a pertinacity that was highly amusing. It was also very interesting to look upward and watch the waves ceaselessly chasing each other overhead, the shape and formation of each wave being clearly indicated by the lines of rippling light that crossed and intermingled with each other in the production of an endless succession of most beautiful and novel effects.The wreck was clearly visible at a distance of some three hundred feet, lying at the base of the reef, which shot steeply up out of the sand, and reached to within about a dozen feet of the sea-level. As the four men approached it was seen that the almost shapeless bulk before them was, as had been anticipated, merely the after part of the ship, the remainder doubtless lying on the other, or inshore, side of the reef. That she had been a sailing-ship was evident, for the hollow steel main and mizzen masts, with a portion of the yards and the standing and running gear still attached to them, were to be seen lying upon the steep slope of the reef, evidently where they had fallen when the ship struck. And from the circumstance that all canvas, except the close-reefed topsails, was furled, Mildmay expressed the opinion that she had struck during heavy weather, and doubtless at night, for it was difficult to understand how a ship could have come stem-on upon the reef during the hours of daylight, on a coast where fog is practically unknown. And, to the four curious observers standing down there alongside the wreck, it was perfectly clear that she had struck with tremendous force, for she had pushed half her length across the obstructing reef, and had ultimately broken in two just forward of the mainmast. The half of her at which they were now looking had slid down the side of the reef with such force that her stern had buried itself in the sand to an extent which rendered it impossible for them to read her name and port of registry on her counter, as they had hoped to do. If, therefore, they desired to ascertain any particulars concerning her, it would be absolutely necessary for one or more of them to climb on board and institute a search of the cabins, which, in consequence of the peculiar posture of the wreck—that is to say, the fact that she was reared nearly on end on her stern—appeared likely to prove a task of very considerable difficulty, not to say danger.Had they been mere ordinary divers, attired in the well-known regulation diving-dress, they would have been unable to communicate with each other, save by the somewhat slow and awkward means of a slate and a piece of chalk. The professor, however, with that foresight which was one of his most remarkable characteristics, had met this difficulty, at the time when the special diving-dresses for the party were in process of manufacture, by the introduction into each helmet of a pair of small but powerful microphones of his own design, with the result that wearers of the dress could hear as distinctly as when they were in the open-air, and could converse together with perfect facility. Hence they were now able to discuss the difficulty that thus unexpectedly confronted them, and arrange a plan of action.For some minutes the four men stood together, contemplating the wreck and considering the situation generally. Then Mildmay said—“It appears to me that the only way is for me to climb up to the skylight, open it, and lower myself down into the cabin by means of a rope’s-end, plenty of which are lying about athwart the deck. That skylight undoubtedly will give me access to the cuddy, and from that I shall probably be able to make my way into the other cabins. It is the captain’s cabin that we particularly want; and I shall probably know better where to look for it than any of the rest of you. One of you, however, had better come up with me, as I may possibly require assistance.”“All right,” answered Sir Reginald; “I will go with you. Shall I go first, or will you?”“I had better go first, I think; then I can help you up,” said Mildmay.And he forthwith laid hold of a rope’s-end, and with some difficulty hauled himself into position above the fore end of the skylight. Having firmly established himself upon it, he proceeded to haul the baronet up after him. Then, between them, they managed to force open the starboard half of the skylight cover, when, swinging his legs over the ledge of the skylight, Mildmay grasped a rope and lowered himself down into the interior of the cuddy.For a moment he could see nothing, for the only light penetrating this interior came down through the skylight, and that was not much; he therefore switched on his electric lamps and looked about him. He found himself standing upon the after bulkhead of the apartment, with his feet on a door which apparently gave access to one of thestern cabins; and stepping aside sufficiently for the purpose, he was in the act of stooping to unfasten the door, when he suddenly found himself enveloped by a number of long, strong, pliant, embracing arms, and violently snatched off his feet! His surprise was so great that for the moment he could not imagine what had happened to him; he knew only that his arms and legs were so tightly pinioned that, despite his utmost exertions, he found it absolutely impossible to move. But knowledge came to him the next moment—the knowledge that he was in the embrace of an enormous octopus! And as he realised this fact, he heard the horrid rasping of the fierce creature’s powerful mandibles upon his helmet.The sound sent a thrill of horror through him, for the thought flashed through his mind, “If the brute should pierce my helmet, I shall be drowned like a rat in a trap!” But a moment later he became reassured, as he remembered the extraordinary strength and toughness of the aethereum of which not only his helmet but his whole suit of armour was composed; and with the revulsion of feeling, he laughed aloud at the amusing character of the situation—for itwasamusing to him to think of the creature’s disappointment at its utter inability to pierce his shell and get at him.But, stay—was the situation really so very amusing after all? For now Mildmay began to realise that the octopus was steadily working its way backward and upward through a big breach in the fore bulkhead of the cabin, carrying him with it; and presently he found himself outside the cabin altogether, and in the open space at the bottom of the companion ladder. But the creature did not pause here. Still working its way upward, it dragged Mildmay along a wide alley-way between the ship’s side and the casing of the companion-way until it reached the bulkhead between this space and the main hold. The straining of the ship, which had eventually resulted in her breaking in two, had also rent this bulkhead apart, leaving an aperture some ten feet wide, and through this in turn the octopus gradually worked its way, until it had passed into what—before the ship broke in two—had been the main hold. And now Mildmay was able to understand what had been greatly puzzling him—how it was that the creature had come to be inside the ship at all; it was evidently through these breaches in the bulkheads that it had made its way; and, just prior to the moment of his seizure, the sailor had caught a momentary shuddering glimpse of something in the cuddy that went far to explain why it had made its way there.That the octopus had some definite objective now became perfectly clear, for it still kept untiringly on its way, forcing its passage this way and that, through the interstices between a confused heap of bales and cases that had formed a part of the ship’s cargo, until at length, after about half an hour’s arduous work, it emerged, clear of everything, into open water, when it at once made for a cave-like aperture in the reef, into which it passed, still firmly clasping its prisoner in the embrace of its snake-like tentacles.And now Mildmay began to realise the serious character of the extraordinary plight in which he thus unexpectedly found himself involved. For it now flashed upon him that, in the astonishment following upon his seizure, he had failed to raise any outcry, with the object of making his friends acquainted with his predicament; indeed, he had been so fully occupied in struggling to free himself from the fettering embrace of his enemy that it had not occurred to him to cry out until it had become altogether too late to make his voice heard; and he now found himself thrust, how deep he knew not, into this submarine cave, but certainly much too far for his voice to reach those outside and bring them to his assistance. And, meanwhile, the octopus still held him in so tenacious a grip that he found it absolutely impossible to free his hands and so get at his two-bladed, electric dagger, with which, as he believed, he could make short work of his antagonist; indeed, every time that he made the slightest attempt to move his limbs, he felt the tentacles still further strengthen their grip upon him. And now that he had time to think of it, he became conscious of the fact that he was feeling pretty completely exhausted by his previous struggles and the extreme violence with which he had been dragged hither and thither in his passage from the wrecked ship’s cuddy to the cave. He was bruised and aching in every joint of his body, and was, furthermore, suffering severely from cramp due to the constraint upon his limbs.How was he to effect his escape? His friends outside could not help him, for the simple reason that they did not know his whereabouts. Doubtless they were by this time beginning to feel uneasy about him—were, perhaps, even instituting a search for him; but such a search as they were likely to make would not benefit him, for the utmost that they could ascertain would be that, after entering the cuddy, he had most mysteriously and unaccountably disappeared. For he was well aware that there was absolutely nothing to show which way he had gone; more than that, he had gone by a way that would have been absolutely impossible to his own unaided efforts. No, he told himself, it was quite useless to look for help from the others; whatever was to be done he himself must do.And then he began to turn over in his mind the possibilities of the situation. How long would the creature be likely to hold him thus prisoner? Would it release him when at length it realised the impossibility of penetrating his armour? And, if so, how long was it likely to be ere the release came? Failing to make a meal of him, the thing would undoubtedly be obliged to go forth, sooner or later, to seek for food. But Mildmay had only the most elementary knowledge as to the habits of the octopus, and he had a hazy idea that, like certain snakes, the creature might only feed at more or less long intervals, in which case he might be held a prisoner for a week or more. This was a distinctly disquieting reflection while it lasted, but it presently occurred to him that it was by no means probable that, let the creature’s habits be what they might, it would retain that vice-like grip upon him for any very lengthened period, and his chance would come when that grip relaxed. And it was an easy step from that conclusion to the next, which was that he must do what he could to cause the grip to relax as quickly as possible. He had already observed that the creature tightened the clasp of its tentacles about him whenever he moved or struggled; and the obvious corollary from this was that, the more quiescent he could remain, the sooner would his opportunity come to wrench an arm free and use his deadly dagger.Meanwhile, on board theFlying Fish, Lethbridge, intent upon making the time pass as pleasantly as possible for the ladies, cooped up below deck in the saloons, conducted them to a window in the dining-saloon, from which the wreck and the reef were clearly visible, and from which they could watch the movements of the four adventurous divers.For some twenty minutes or so after the quartette had left them, the occupants of the saloon had to be content with such interest and amusement as was to be obtained by observing the movements of the numerous fish outside, including a little thrill of horror when a big shark, which went drifting aimlessly past, turned aside for a moment to thrust his great shovel-snout up against the tremendously thick and especially toughened plate-glass window out of which they were gazing. They were at once full of apprehension lest the monster should remain in the neighbourhood, and attack the divers upon their appearance on the sandy floor below; and Lady Elphinstone even begged the colonel to go down below and warn the adventurers of its proximity as well as urge them to defer their excursion. But Lethbridge laughed so heartily at the idea of their being in any danger from a mere shark, and explained to them so clearly that the shark would have absolutely no chance whatever against men equipped as the divers were, that they permitted themselves to be reassured.And while they were all discussing the matter, the four divers suddenly appeared, forcing their way somewhat laboriously through the water in the direction of the wreck. They saw the little party reach the great mass and stand for some few minutes, evidently in consultation; and finally they saw one of them climb up the wreck and then assist another of the party to mount beside him.“Mildmay and Elphinstone,” commented Lethbridge, as he looked over Ida’s shoulder.“How do you know that, Colonel?” demanded Lady Olivia. “To me they look all precisely alike, except, of course, that the professor is much stouter than the others. It is impossible for him to conceal his identity, even by encasing himself in a suit of armour.”“No; quite true,” laughed Lethbridge. “The worthy von Schalckenberg’s figure is such that one is bound to recognise him as far as one can see him. As to your other question, well, I recognised the first man as Mildmay by his actions. He is a sailor all over, and as strongly indicated by his sailor-like motions as the professor is by his figure. And I take the other to be your husband, because this is Colonel Sziszkinski’s first appearance under water; moreover, Elphinstone is not the man to ask another to do anything which he himself can do. Ah, there goes Mildmay down through the ship’s skylight. He is doubtless going to search the cabins for anything he can find that will help to establish her identity. We shall see no more of him for the next half-hour or so, I suspect.”They saw Sir Reginald lean over the edge of the skylight for a moment, and look down into the ship’s interior; and then, as they watched, he seated himself composedly upon the fore end of the skylight, upon which he had been standing, and, with folded arms, leaned back against the almost vertical deck, with the stump of the mizzenmast and a quantity of wreckage that rested upon it, just above his head, overarching him in a sort of canopy. Then they saw the professor and his friend walking quietly about the wreck, examining it, and pointing out to each other such peculiarities as attracted their attention. And when the two men had exhausted the interest that attached to the wreck, the watchers saw them climb somewhat awkwardly up it and seat themselves beside Sir Reginald, who had two or three times peered down into the interior of the skylight, and now seemed to be exhibiting some signs of uneasiness.“Sir Reginald is beginning to grow fidgety at Mildmay’s long stay below, I fancy,” remarked Lethbridge. “But he need not; Mildmay is a sailor, and a navy man at that; and he may be trusted to take care of himself. He is very thorough in his methods, and you may depend that—Hillo! What the—phew! it is an octopus, and I’ll be shot if he hasn’t—”The ex-colonel pulled himself up short, and glanced anxiously at the faces of his companions. Had either of them seen? He noticed a look of horror and strong repugnance upon the faces of all three; but the horror was the kind that raises from the sight of some dreadful object, not the kind that is aroused upon witnessing some especially dreadful occurrence. He waited a moment to give one or another of them an opportunity to speak. He hoped they hadnotseen. He himself had only caught the barest momentary glimpse, as the creature shot suddenly up out of the body of the wreck, before it turned; but that glimpse was enough:he had seen!“Oh, what a dreadful creature!” exclaimed Lady Olivia, turning a pale face to Lethbridge. “What is it, Colonel, and where did it come from?”Evidentlyshehad not seen!“It is an octopus, or giant squid, as some people call it. It is very similar to the ordinary cuttlefish, only, of course very much larger. And, so far as I could see, it appeared to spring from the hull of the wreck. If you will excuse me for a moment, ladies, I will go to the pilot-house and endeavour to give our friends yonder some intimation of its presence; the professor will be interested to know that a genuine giant squid is within a few yards of him.”And thus lightly speaking, Lethbridge sauntered quietly out of the saloon, closed the door carefully behind him, and dashed at break-neck speed for the pilot-house.He had already made up his mind what to do, and doubtless those other fellows would understand; they were quick-witted enough, surely, to grasp the meaning of such an action on his part.His thoughts had reached thus far when he arrived in the pilot-house. Grasping the switch-handle of the great electric lantern, he proceeded to switch the light on and off rapidly, which act had the effect of almost immediately attracting the attention of the three men who were sitting on the skylight of the wreck. He saw them look at each other, as though speaking, and then von Schalckenberg rose to his feet and raised both hands above his head, to indicate that he was attending. And, thereupon, Lethbridge immediately began to signal, in the Morse code, by means of long and short flashes, the message—“Mildmay in danger. Seized by octopus and carried into cave some distance above your heads.”To this message the professor at once replied by waving his arms in accordance with the “flag-waving” system used in the British navy and army—“Right. We go to his rescue. Guide us to the cave.”Lethbridge gave the flash that indicated his comprehension of the communication, and then, with the switch-handle still in his hand, intently watched, through one of the pilot-house windows, the movements of the three. He saw them lower themselves down on to the sand, and immediately begin to climb up the rugged side of the reef. The surface of the rocks was slippery with weed, and their progress was, therefore, painfully slow; but at length they reached a point above and clear of the wreck, and von Schalckenberg then turned and faced the pilot-house, evidently asking for guidance.“Go higher and bear to your right,” signalled Lethbridge; and the men resumed their climb.They were now making directly for the spot at which the octopus had disappeared, and afewminutes later they reached a ledge, with the cave immediately in front of them. The professor now again faced round inquiringly, and Lethbridge signalled—“That is the spot.”Von Schalckenberg threw up his arms to indicate that he understood; and then Lethbridge saw the three men stand and confer together for a moment. Then, drawing their daggers and switching on their lights, they all three plunged into the cave and vanished, leaving the solitary watcher in the pilot-house in a state of painful suspense that endured for fully ten minutes. At length, however, the professor and one of the others reappeared, each of them dragging at a long, limp tentacle; and in another moment the huge body of the octopus came into view with the remaining two men pushing it vigorously from behind. As it reached the edge of the ledge the professor and his companion stepped round to assist the other two, and presently the great unwieldy body went rolling limply and lifelessly down the face of the reef until it lay motionless upon the sand. Then the four men made their way carefully down after it, when, having reached the sand, they turned and bent their footsteps in the direction of theFlying Fish.

The two succeeding days were very fully occupied upon the somewhat difficult and delicate task of effecting an equal division of the fabulously rich haul of rubies that they had so easily acquired in so short a time; and on the third day—being Sunday—everybody took a rest, as was usual with them whenever possible.

But on the following Monday morning, after breakfast, theFlying Fishrose into the air, and, moving out to sea, proceeded to the reef upon which the unknown ship had been wrecked.

That skylight undoubtedly will give me access to the cuddy, and from that I shall probably be able to make my way into the other cabins.

For it now flashed upon him that, in the astonishment following upon his seizure, he had failed to raise any outcry, with the object of making his friends acquainted with his predicament; indeed, he had been so fully occupied in struggling to free himself from the fettering embrace of his enemy that it had not occurred to him to cry out until it had become altogether too late to make his voice heard; and he now found himself thrust, how deep he knew not, into this submarine cave, but certainly much too far for his voice to reach those outside and bring them to his assistance. And, meanwhile, the octopus still held him in so tenacious a grip that he found it absolutely impossible to free his hands and so get at his two-bladed, electric dagger, with which, as he believed, he could make short work of his antagonist; indeed, every time that he made the slightest attempt to move his limbs, he felt the tentacles still further strengthen their grip upon him. And now that he had time to think of it, he became conscious of the fact that he was feeling pretty completely exhausted by his previous struggles and the extreme violence with which he had been dragged hither and thither in his passage from the wrecked ship’s cuddy to the cave. He was bruised and aching in every joint of his body, and was, furthermore, suffering severely from cramp due to the constraint upon his limbs.

How was he to effect his escape? His friends outside could not help him, for the simple reason that they did not know his whereabouts. Doubtless they were by this time beginning to feel uneasy about him—were, perhaps, even instituting a search for him; but such a search as they were likely to make would not benefit him, for the utmost that they could ascertain would be that, after entering the cuddy, he had most mysteriously and unaccountably disappeared. For he was well aware that there was absolutely nothing to show which way he had gone; more than that, he had gone by a way that would have been absolutely impossible to his own unaided efforts. No, he told himself, it was quite useless to look for help from the others; whatever was to be done he himself must do.

And then he began to turn over in his mind the possibilities of the situation. How long would the creature be likely to hold him thus prisoner? Would it release him when at length it realised the impossibility of penetrating his armour? And, if so, how long was it likely to be ere the release came? Failing to make a meal of him, the thing would undoubtedly be obliged to go forth, sooner or later, to seek for food. But Mildmay had only the most elementary knowledge as to the habits of the octopus, and he had a hazy idea that, like certain snakes, the creature might only feed at more or less long intervals, in which case he might be held a prisoner for a week or more. This was a distinctly disquieting reflection while it lasted, but it presently occurred to him that it was by no means probable that, let the creature’s habits be what they might, it would retain that vice-like grip upon him for any very lengthened period, and his chance would come when that grip relaxed. And it was an easy step from that conclusion to the next, which was that he must do what he could to cause the grip to relax as quickly as possible. He had already observed that the creature tightened the clasp of its tentacles about him whenever he moved or struggled; and the obvious corollary from this was that, the more quiescent he could remain, the sooner would his opportunity come to wrench an arm free and use his deadly dagger.

Meanwhile, on board theFlying Fish, Lethbridge, intent upon making the time pass as pleasantly as possible for the ladies, cooped up below deck in the saloons, conducted them to a window in the dining-saloon, from which the wreck and the reef were clearly visible, and from which they could watch the movements of the four adventurous divers.

For some twenty minutes or so after the quartette had left them, the occupants of the saloon had to be content with such interest and amusement as was to be obtained by observing the movements of the numerous fish outside, including a little thrill of horror when a big shark, which went drifting aimlessly past, turned aside for a moment to thrust his great shovel-snout up against the tremendously thick and especially toughened plate-glass window out of which they were gazing. They were at once full of apprehension lest the monster should remain in the neighbourhood, and attack the divers upon their appearance on the sandy floor below; and Lady Elphinstone even begged the colonel to go down below and warn the adventurers of its proximity as well as urge them to defer their excursion. But Lethbridge laughed so heartily at the idea of their being in any danger from a mere shark, and explained to them so clearly that the shark would have absolutely no chance whatever against men equipped as the divers were, that they permitted themselves to be reassured.

And while they were all discussing the matter, the four divers suddenly appeared, forcing their way somewhat laboriously through the water in the direction of the wreck. They saw the little party reach the great mass and stand for some few minutes, evidently in consultation; and finally they saw one of them climb up the wreck and then assist another of the party to mount beside him.

“Mildmay and Elphinstone,” commented Lethbridge, as he looked over Ida’s shoulder.

“How do you know that, Colonel?” demanded Lady Olivia. “To me they look all precisely alike, except, of course, that the professor is much stouter than the others. It is impossible for him to conceal his identity, even by encasing himself in a suit of armour.”

“No; quite true,” laughed Lethbridge. “The worthy von Schalckenberg’s figure is such that one is bound to recognise him as far as one can see him. As to your other question, well, I recognised the first man as Mildmay by his actions. He is a sailor all over, and as strongly indicated by his sailor-like motions as the professor is by his figure. And I take the other to be your husband, because this is Colonel Sziszkinski’s first appearance under water; moreover, Elphinstone is not the man to ask another to do anything which he himself can do. Ah, there goes Mildmay down through the ship’s skylight. He is doubtless going to search the cabins for anything he can find that will help to establish her identity. We shall see no more of him for the next half-hour or so, I suspect.”

They saw Sir Reginald lean over the edge of the skylight for a moment, and look down into the ship’s interior; and then, as they watched, he seated himself composedly upon the fore end of the skylight, upon which he had been standing, and, with folded arms, leaned back against the almost vertical deck, with the stump of the mizzenmast and a quantity of wreckage that rested upon it, just above his head, overarching him in a sort of canopy. Then they saw the professor and his friend walking quietly about the wreck, examining it, and pointing out to each other such peculiarities as attracted their attention. And when the two men had exhausted the interest that attached to the wreck, the watchers saw them climb somewhat awkwardly up it and seat themselves beside Sir Reginald, who had two or three times peered down into the interior of the skylight, and now seemed to be exhibiting some signs of uneasiness.

“Sir Reginald is beginning to grow fidgety at Mildmay’s long stay below, I fancy,” remarked Lethbridge. “But he need not; Mildmay is a sailor, and a navy man at that; and he may be trusted to take care of himself. He is very thorough in his methods, and you may depend that—Hillo! What the—phew! it is an octopus, and I’ll be shot if he hasn’t—”

The ex-colonel pulled himself up short, and glanced anxiously at the faces of his companions. Had either of them seen? He noticed a look of horror and strong repugnance upon the faces of all three; but the horror was the kind that raises from the sight of some dreadful object, not the kind that is aroused upon witnessing some especially dreadful occurrence. He waited a moment to give one or another of them an opportunity to speak. He hoped they hadnotseen. He himself had only caught the barest momentary glimpse, as the creature shot suddenly up out of the body of the wreck, before it turned; but that glimpse was enough:he had seen!

“Oh, what a dreadful creature!” exclaimed Lady Olivia, turning a pale face to Lethbridge. “What is it, Colonel, and where did it come from?”

Evidentlyshehad not seen!

“It is an octopus, or giant squid, as some people call it. It is very similar to the ordinary cuttlefish, only, of course very much larger. And, so far as I could see, it appeared to spring from the hull of the wreck. If you will excuse me for a moment, ladies, I will go to the pilot-house and endeavour to give our friends yonder some intimation of its presence; the professor will be interested to know that a genuine giant squid is within a few yards of him.”

And thus lightly speaking, Lethbridge sauntered quietly out of the saloon, closed the door carefully behind him, and dashed at break-neck speed for the pilot-house.

He had already made up his mind what to do, and doubtless those other fellows would understand; they were quick-witted enough, surely, to grasp the meaning of such an action on his part.

His thoughts had reached thus far when he arrived in the pilot-house. Grasping the switch-handle of the great electric lantern, he proceeded to switch the light on and off rapidly, which act had the effect of almost immediately attracting the attention of the three men who were sitting on the skylight of the wreck. He saw them look at each other, as though speaking, and then von Schalckenberg rose to his feet and raised both hands above his head, to indicate that he was attending. And, thereupon, Lethbridge immediately began to signal, in the Morse code, by means of long and short flashes, the message—

“Mildmay in danger. Seized by octopus and carried into cave some distance above your heads.”

To this message the professor at once replied by waving his arms in accordance with the “flag-waving” system used in the British navy and army—

“Right. We go to his rescue. Guide us to the cave.”

Lethbridge gave the flash that indicated his comprehension of the communication, and then, with the switch-handle still in his hand, intently watched, through one of the pilot-house windows, the movements of the three. He saw them lower themselves down on to the sand, and immediately begin to climb up the rugged side of the reef. The surface of the rocks was slippery with weed, and their progress was, therefore, painfully slow; but at length they reached a point above and clear of the wreck, and von Schalckenberg then turned and faced the pilot-house, evidently asking for guidance.

“Go higher and bear to your right,” signalled Lethbridge; and the men resumed their climb.

They were now making directly for the spot at which the octopus had disappeared, and afewminutes later they reached a ledge, with the cave immediately in front of them. The professor now again faced round inquiringly, and Lethbridge signalled—

“That is the spot.”

Von Schalckenberg threw up his arms to indicate that he understood; and then Lethbridge saw the three men stand and confer together for a moment. Then, drawing their daggers and switching on their lights, they all three plunged into the cave and vanished, leaving the solitary watcher in the pilot-house in a state of painful suspense that endured for fully ten minutes. At length, however, the professor and one of the others reappeared, each of them dragging at a long, limp tentacle; and in another moment the huge body of the octopus came into view with the remaining two men pushing it vigorously from behind. As it reached the edge of the ledge the professor and his companion stepped round to assist the other two, and presently the great unwieldy body went rolling limply and lifelessly down the face of the reef until it lay motionless upon the sand. Then the four men made their way carefully down after it, when, having reached the sand, they turned and bent their footsteps in the direction of theFlying Fish.

Chapter Twenty Two.The Pirate Cruiser.When, having reached the dining-room of theFlying Fish, Mildmay changed out of his diving-suit into his ordinary clothes, it was found that he was so severely bruised and strained that the professor, in his capacity of emergency medical adviser to the party, insisted upon his immediate retirement to his cabin and his bed. There the worthy man subjected him to so vigorous a massage, and so generous an anointing with a certain embrocation of his own concocting, that two days later the genial sailor was again able to be up and about. And, meanwhile, Sir Reginald and Colonel Sziszkinski continued the examination of the wreck, but unfortunately without any satisfactory result; for although they succeeded in finding the captain’s cabin, and bringing therefrom, and from some of the other cabins, a considerable number of documents, it was found that, owing to their long submersion, they had become so completely sodden that any attempt to handle them, while still wet, reduced them to pulp; and when the alternative of carefully drying them was tried, they became so exceedingly brittle that they simply crumbled to pieces, while, even on the fragments that they contrived to preserve, the writing was so nearly obliterated as to be quite undecipherable. Nevertheless, they preserved as much as they could, in the hope that the experts in such matters, at home, might be more successful than themselves. But it may here be stated that the experts also failed; and the name and nationality of the ship, as well as the identity of those who perished in her at the murderous hands of the savage M’Bongwele, remain a mystery to this day.On the third day following Mildmay’s adventure with the octopus, theFlying Fishbeing once more berthed on the beach near the spot where the party had made their amazingly rich haul of rubies, all hands had adjourned to the deck after dinner to enjoy the delicious coolness of a breeze off the sea. Ida had gone to bed somewhat earlier than usual that evening, complaining that she was not feeling very well, her symptoms being a feverish pulse and a slightly increased temperature, toward the alleviation of which the professor had administered a fairly liberal dose of quinine.Sir Reginald and Lady Olivia, naturally anxious in everything relating to their only child’s health, were discussing the matter with von Schalckenberg, who was endeavouring, without his usual success, to reassure the pair, who were of opinion that the African climate was to blame for their daughter’s indisposition.“Well,” at length said the professor, “if you really think so, nothing in this world is easier than for us to change it. We can ascend into the atmosphere to any height we please, thus obtaining any desired temperature; we can, in a veryfewhours, reach any other country that you would care to visit; or, which is perhaps better than either, we can go out to sea and leisurely cruise about in any required direction, and in absolutely pure air.”“Hear, hear!” exclaimed Mildmay, who, although chatting with Mlle. Feodorovna, had overheard the professor’s words. “There is no sanatorium like old ocean; no doctor like Father Neptune, believe me, Elphinstone. A week’s cruise somewhere away out there to the eastward would set the little darling up far more effectively than all the professor’s drugs. Try it, man; it can do no harm; and I’ll bet you a—a—well, let us say a peck of rubies, that you’ll not regret it.”“Well, while declining your modest little bet, Mildmay, I really feel more than half inclined to act upon your suggestion,” answered Sir Reginald, with a laugh. “There is no particular reason why we should not, I fancy, beyond the fact that the professor wants to shoot one or two of those new zebras, and we can easily return here for that purpose. The fact is that I am beginning to tire a little of shore life, and I think a trip out to sea would do us all good. What do the rest say?”“So far as I am concerned I will gladly go anywhere, or do anything, for Ida’s sake,” answered Lethbridge.“Thanks, old chap; I know you will,” said Sir Reginald. “What say you, Colonel?”—to Sziszkinski—“would you like to go with us, or would you prefer to remain here until our return, and go in for shooting under the aegis of our friend Lobelalatutu?”“Thank you very much, Sir Reginald, for offering me the choice,” answered the Russian. “I prefer to accompany you. I am quite of your own opinion, that a change will do us all good; and, like my friend, Monsieur Lethbridge, I will gladly go anywhere and do anything for the sake of the charming little Mademoiselle Ida.”“And you, Mademoiselle?” asked Sir Reginald, turning to Mildmay’s companion.“I?” she answered. “Oh, Monsieur Edouard—Sir Reginald, I mean—I am so happy on board this beautiful ship that I feel I shall never want to leave her. Please accept papa’s answer as mine also.”“I am really very much obliged to you all for so cheerfully and readily falling in with my wishes,” said Sir Reginald. “Very well, then; it is settled that we go to sea for a week or two, as the mood takes us. Now, the next question is, Where shall we go? We certainly ought to have some definite objective, don’t you think? Does any one desire to go anywhere in particular?”There was silence for a minute or two. Apparently no one wished to go anywhere in particular; or, if they did, they were not sufficiently eager to feel called upon to mention the fact.At length Lady Olivia looked up.“Has nobody a suggestion to make?” she asked, with a smile. “Then I will make one that I think will be sympathetically received by at least one of us—yourself, my dear Feodorovna. I have long had the wish to possess a really fine set of pearls, not the kind that one can go into any jeweller’s shop and buy, you know, but something quite out of the common; and it appears to me that this voyage of ours affords just the opportunity for somebody to fish those pearls up for me from the bottom of the sea. And I dare say that your papa—or somebody else—would be quite willing to do the same for you, dear. What do you say?”“What do I say?” repeated the lovely young Russian. “Why, that I simply adore pearls.”“Then, I think, Reginald, that you have your answer,” said Lady Olivia, turning to her husband.“All right, dear,” he answered. “Pearl-fishing will suit me down to the ground; and if the ocean holds pearls enough to satisfy you, you shall have them. Now, Professor—Mildmay—where must we go in order to get those pearls? For, of course, we must go to some definite spot to look for them; we can’t go grubbing along the sea-bottom at random until we happen to stumble upon a bed of pearl-oysters, you know.”“The most famous pearl-fishing grounds are situated in the Persian Gulf and off the coast of Ceylon,” answered Mildmay. “And I believe,” he added, “that in both cases they are Government property, and strictly preserved. But I have no doubt there are plenty of oyster-beds which are beyond the reach of the ordinary pearl-diver; and it is one of those that we must seek. We shall not be poaching on anybody’s preserves if we do this; and shall also stand a better chance of securing some good specimens.”“Before you come to any definite decision, I should like to refer to a rather interesting manuscript book that I have in my cabin—the book that I recovered from the sunken wreck of theDaedalus, under circumstances which, perhaps, yet remain in your memory,” observed von Schalckenberg, addressing Sir Reginald. “I seem to remember,” he continued, “having come across a passage in it relating to a bed of pearl-oysters of immense value, the situation of which was then unknown to any one except the writer. If you will excuse me a moment, I will go and fetch it.”“By all means,” said Sir Reginald. “From what you say, Professor, it would appear that the bed to which you refer is the identical one we want to find.”The professor accordingly retreated; and presently returned with a small, leather-bound, and much discoloured book in his hand. His forefinger was between the pages, and he opened the book there.“Yes,” he said, “I thought I was not mistaken. Here is the passage, under the heading of ‘Pearls. In Longitude 155 degrees 32 minutes 17 seconds East, and exactly under the Equator, there exists a small atoll, unnamed, and, I believe, unknown, unless it be to the natives of Matador and Greenwich Islands, which are in its neighbourhood. The islet, which is uninhabited, is little more than a mere rock, about a quarter of a mile long, and some fifty feet wide, over which the sea makes a clean breach in heavy weather; but the lagoon is about five miles long and three miles wide, with good anchorage for ships in a pretty uniform depth of ten fathoms. Two miles due west of this island there is a shoal, some seven miles long, by from two to four miles wide, with twenty-eight feet of water over it. And this shoal is almost entirely covered with pearl-oysters, yielding some of the finest and most perfect gems that I have ever seen.’ Now, what think you of that, my friend. Is that good enough for you?” demanded the professor.“Quite good enough,” answered Sir Reginald. “Now, skipper,” he continued, turning to Mildmay, “how far off is this famous oyster-bed, and how long will it take us to get there?”“What did you say is the position of the spot, Professor?” asked Mildmay.The professor restated the longitude.“Um!” observed Mildmay, figuring upon a piece of paper that he drew from his pocket; “it is a goodish step from here to there! roughly, about seven thousand miles, as the crow flies. As to how long it will take us to get there; we can do the distance in sixty hours, by going aloft into the calm belt, shutting ourselves in, and going full speed ahead. Otherwise—”“Thanks, very much; and never mind the ‘otherwise,’” answered Sir Reginald. “This is going to be aseatrip; and we are going to do at least a part of it in leisurely fashion, say, about ten to fifteen knots an hour. When we are tired of that, and at night, we can go aloft and put on the speed if we wish. And, now that I come to think of it, is there any reason why we should not start at once?”No one, it appeared, had any reason to advance against the baronet’s proposal. Accordingly, he and Mildmay forthwith adjourned to consult the chart and lay off the course; and ten minutes later the remainder of the party, who were still sitting on deck, awaiting the return of the absentees, became conscious of the fact that the night-breeze had suddenly strengthened; and when they looked about them in search of an explanation, they saw the sea about three hundred feet beneath them, and the land slipping away into the gloom of the night astern.The travellers had been at sea a week, pottering along on the surface during the day, and rising some three hundred feet into the air at night—just high enough, in fact, to take them over and clear of the masts of any ships that they might happen to encounter during the hours of darkness—maintaining a tolerably uniform speed of ten knots through the air—not counting the acceleration or retardation of speed due to the varying direction and strength of the several winds that they met with. Thus they had been able to sleep at night with wide open ports, to their great comfort and enjoyment, and the manifest improvement of their health, as was particularly exemplified in the case of little Ida, who was by this time as well as even her parents could desire.The hour was eleven o’clock in the forenoon—six bells, Mildmay called it—and the ship had been running on the surface for about an hour. The entire party were sitting out on deck under the awnings, amusing themselves in various ways, the two ladies, each with a book on her lap, to which it is to be feared she was giving but scant attention, and Ida, her father, Lethbridge, and the Russian colonel playing bull. It was a most lovely day, the sky without a cloud, the water smooth, and a soft but refreshing breeze was breathing out from the southward. The ship was steering herself, the self-steering apparatus having been thrown into action, as no other craft were in sight.The horizon was not to remain bare for very long, however; for just as Mildmay rose to his feet with some idea of going below, the dull, muffled boom of a distant gun was heard, and, everybody at once looking round the horizon in search of the source of so very novel an occurrence, the topmast-heads and smoke of a steamer were seen just showing above the ocean’s rim, about three points on the starboard bow. She seemed to be in a hurry, too, if the dense volumes of smoke that poured from her as yet unseen funnels were to be taken as any criterion.“Now, what craft will that be?” exclaimed “the skipper,” as he studied the two mastheads attentively. “A liner, I should say, by the length of her between her masts. Probably an ‘Orient,’ ‘Orient-Pacific,’ or ‘X. and Z.’ boat. But surely she did not fire that gun? And, if she did not—oho! what is this? There is another craft astern of her! I can just make out her mastheads rising above the horizon. Now, did number two fire that gun; and, if so, why? I must get my glasses; this promises to be interesting. And we shall see more of it presently; they are crossing our hawse in a diagonal direction, and edging this way.”The game of bull was forthwith abandoned, as being of much less interest than the advent of two strange ships on the scene—for, singularly enough, these were the first craft that they had sighted since leaving the African coast—and everybody at once made a dash below for his or her own especial pair of binoculars.The two strange craft were coming along at a great rate, and rising above the horizon very quickly; thus, by the time that Mildmay returned to the deck with his glasses in his hand, the leading ship was almost straight ahead, and had risen sufficiently to show her chart-house above the horizon, and to enable “the skipper” to see that she carried a wheel-house on top of the fore end of it, and a short awning abaft the wheel-house.“Yes,” he muttered to himself, “she is a liner, undoubtedly; and an X. and Z. boat at that, unless I am greatly mistaken. Two masts—the mainmast stepped a long way aft; and two funnels amidships, pretty close together—yes; she is an X. and Z.; I’ll bet my hat on that. And she is steaming for all she is worth. I can see the ‘white feather’ blowing away from the top of her waste-pipes. Now, is she racing with that other chap; or—is she running away from him?”He turned his binoculars upon the sternmost ship, which was also coming along at a great rate, and gradually lifting above the horizon. About half the length of her masts—two of them—was now showing; and as Mildmay focussed his lenses upon them an ejaculation of astonishment escaped his lips.“A man-o’-war, by the Lord Harry!” he exclaimed. “Yes; there are her upper signal-yards, and her fighting-tops below them, clear enough. By the piper, this is growing interesting indeed. Now, who and what is she? and why is she chasing a British liner?—for sheischasing her, beyond a doubt!”“Well, Mildmay, what do you make of them?” inquired Sir Reginald, as he at this moment stepped out on deck.“I make of it,” answered Mildmay, “that the leading ship is an X. and Z. liner steaming for all she is worth; and that the second ship is a man-o’-war—a second-class cruiser, I should say—chasing her!”“The dickens you do!” returned Sir Reginald. “Then what does it mean? Is it not something rather unusual?”“It is so extremely unusual, that I am going to ask your permission to haul up a point or two, presently, that we may investigate the matter,” answered Mildmay. “There is only one possible explanation of it; and that is that war has quite suddenly broken out between England and some other Power. And yet that can scarcely be, either; for when we left home everything was quite quiet; the political horizon was as clear as it ever is, and—dashed if I can understand it. But anyhow, Elphinstone, I suppose we are not going to jog quietly along and see a British ship bullied by a foreigner without having a word or two to say about it, are we?”“Not much!” answered Sir Reginald, emphatically, and with a flash of the eye that delighted Mildmay. “I know nothing of these matters,” he continued, “or how to proceed; but you do; so take charge, old chap, and give us your orders. We will obey them to the letter, I promise you.”“A thousand thanks,” answered Mildmay. “Of course I need not tell you that to interfere in a case of this kind, with no knowledge of the facts, is a somewhat ticklish business. But, all the same, that is not going to stop me. I see, yonder, a British ship flying from a stranger; and with your kind permission I am going to lend her a hand.”He raised his glasses to his eyes again. The hull of the leading ship had by this time almost topped the horizon, and it was now possible to see something of her shape. She was a fairly big craft, measuring, according to Mildmay’s estimate, about eight thousand tons; and her whole shape and appearance confirmed him in his original conviction that she was one of the X. and Z. Company’s boats. She flew no flag at her masthead, it is true; but Mildmay could now see that she had hoisted a blue ensign on her ensign staff.“Under the command of a R.N.R. man,” he commented, as he saw this. “All right, old man; there is a friend within a few miles of you, whose proximity you probably don’t suspect; and we will see that you don’t come to any harm. Now let us have a look at t’other chap.”The second craft was still hull-down; but her masts, funnels, tops of her ventilators, and the head of her ensign staff were all visible; and Mildmay noticed that she was showing no colours. This fact rendered the whole affair more puzzling than ever; for there could be no possible doubt that she was chasing the liner, and for a man-o’-war openly and undisguisedly to chase another ship, and not show her colours, was unprecedented, and most certainly not in accordance with any recognised rule of warfare.Meanwhile, the rest of the party had come on deck, and were all intently watching the two ships through their binoculars as they animatedly discussed the puzzling situation.“When do you intend to haul up, ‘skipper’?” asked Sir Reginald.“Not yet,” answered Mildmay. “Perhaps in about ten minutes’ time—unless anything occurs of a character that would make it desirable to do so earlier. I want to see a little more of the game first.”“Then there you have it!” exclaimed Lethbridge, as a flash, followed by a puff of brilliant white smoke, issued from the bows of the pursuing ship.A jet of foam leaped up from the surface of the sea, about half a mile astern of the liner, and dissolved like steam in the dazzling sunshine. Then the boom of the gun came floating down to the ears of the watchers.“A four-inch, by the sound of it,” remarked Mildmay. “And shotted, too. Clearly, the fellow is in earnest, whoever he may be. Now, what the dickens is the explanation of this enigma? And what is the nationality of the craft?”“Can’t you tell by the build of her?” demanded Lethbridge. “I have always understood that you sailors had but to look at a ship to tell her nationality at once; at least that is the impression that one gathers from the general run of sea novels.”“Yes,” answered Mildmay. “But that refers to the old days of wooden ships. There was a distinctiveness in the model of the wooden ship that was an almost infallible index to her nationality. But nowadays ships—and particularly war-ships—are built so much alike in shape that, except in a few rather extreme cases, it is practically impossible to identify them. That fellow, yonder, for instance, might be British, Dutch, German, Austrian, Italian, or Japanese, for all that one can tell by merely looking at him. Ah, there goes another gun!”The shot this time struck somewhat nearer, throwing up three successive jets of water, the last of which appeared to be unpleasantly close to the stern of the chase.“The fellow is overhauling her,” exclaimed Mildmay. “Now, Elphinstone, with your permission, I will shift our helm and alter our course forty-five degrees to the nor’ard.”And, so saying, he entered the pilot-house; and a moment later the watchers saw the two distant craft swing back along the horizon until the leading ship bore two points on theFlying Fish’sstarboard bow.“If you have no objection, Sir Reginald, I should like a torpedo-shell put into our bow tube,” observed Mildmay, as he emerged from the pilot-house.“Certainly,” answered Sir Reginald; “I will go below and put one in at once.”“Better let me do it,” interposed the professor. “I know more about the working of them than you do; and, moreover, I am not so profoundly interested in this affair as you all seem to be. Besides, I shall not be gone longer than five minutes at the utmost.”And, Sir Reginald offering no objection, the worthy man turned away and vanished through the pilot-house door.The leading ship was by this time within about five miles of theFlying Fish, and steering a course that would take her square across the bows of the latter; the two—or, indeed, the three—ships were therefore nearing each other fast, and the men fell to debating the question whether or not theFlying Fishhad yet been seen by either of the strangers. The craft was in her usual surface-running trim; that is to say, considerably more than half of her polished hull was submerged, leaving little to be seen except her small superstructure and her pilot-house, both of which were painted a delicate blue-grey colour that would be scarcely visible against the horizon astern. The chances, therefore, were strongly in favour of her invisibility. On the other hand, there was just a possibility that some keen eye aboard the liner, anxiously scanning the horizon in quest of help, might have sighted her; in which case a glimpse of the white ensign might be comforting. Mildmay therefore went to the flag-locker and drew forth the white ensign which, in virtue of his being a member of the Royal Yacht Squadron, Sir Reginald was entitled to fly, and ran it up to the truck of the ensign staff.Whether it had been seen or not was difficult to say, for nothing in particular followed upon its exhibition, unless the discharge of another gun from the pursuing ship might be taken as a reply. And this time the shot went home to its mark; for as the observers turned their glasses upon the chase, her mainmast was seen to totter and fall by the board, cut short off by the deck. Luckily the spar did not go over the side, but lay, fore-and-aft, inboard; otherwise the rigging might have fouled the propeller and brought the ship to a standstill. As it was, she continued her flight as though nothing had happened.“This matter has gone quite far enough,” exclaimed Mildmay, sharply, as he saw the liner’s mast fall. “Come inside, all of you, if you please. We may be under fire in another minute or two. Perhaps the ladies had better go below until this affair is settled—if you will be so kind,” he added, with a bow to Lady Olivia as she passed in through the pilot-house door, outside which he was standing.When all the rest had entered, he followed, closing the door behind him, and at once ascended to the working chamber of the pilot-house, whither Sir Reginald and Lethbridge had preceded him. His first act was to increase the speed of theFlying Fishto thirty knots; and as he moved the lever forward, admitting a larger flow of vapour to the engine-cylinders, Lethbridge, who was standing at one of the windows, with his binoculars to his eyes, turned and said—“What do you think of that, Mildmay?”“What do I think of what?” retorted Mildmay, stepping to his side.“That!” answered Lethbridge, pointing to the pursuing ship and handing over his glasses for the other to use. “The unknown has just hoisted to her masthead a black flag with a white skull and cross-bones in its centre. Is not that—?”“Nonsense!” exclaimed Mildmay. “You surely do not mean it. Let me have a look.”He raised the glasses to his eyes for a moment and stared through them as though he felt that he could scarcely credit the evidence of his own senses. Then, as he thrust the glasses back into his friend’s hand, he exclaimed—“The ‘Jolly Roger,’ as I am a living sinner! Well, that ‘takes the cake,’ and no mistake! Yes; the fellow is undoubtedly a genuine, up-to-date, twentieth-century pirate. If it had not been for that last shot I might have been inclined to believe the whole affair an elaborate joke in the very worst taste; but a man does not shoot another fellow’s mast away as a joke. No; that chap means business—and so doI! Ah, another shot! and—yes, here it comes—he is firing at us! Not at all badly aimed, either.”As he spoke the loud rushing sound of the shot broke upon their ears; and a moment later it struck the sea about three yards astern of theFlying Fish, sending a column of white, steam-like foam and spray shooting some twenty feet into the air. Almost instantly another shot followed, which, judging from the sound, must have passed close over the pilot-house roof; to be followed, a few seconds later, by a third, which struck the water within a fathom of the ship’s sharp nose, which was just level with the water’s surface, and, owing to the speed of the ship, was sending up a fine, perpendicular jet of glassy water some ten feet high.“Confound the fellow’s impudence!” exclaimed Sir Reginald. “Does the rascal think that he is going to make a prize ofus? A fine rich prize we should make, too, did he but know it!”“It is not that,” explained Mildmay. “It is the white ensign that he doesn’t like the look of. He probably takes us for some new-fangled sort of British gun-boat, bent upon interfering with his little game; and he wants to disable us. He is one of those pestilently persistent fellows who won’t take a hint and sheer off; he is as full of obstinacy as was the mammoth that chased me over yonder,”—with a jerk of his thumb toward the north—“on our first trip, and must be treated as we treated that mammoth. For if we don’t kill him, he will kill us—if he can. You see? Here comes another shot!”It was a very close shave that time, the missile passing so close athwart the front of the pilot-house that its wind actually came, in a sudden, violent gust, in through the pilot-house window.“We must put a stop to this at once, or the fellow will do us a mischief,” exclaimed Mildmay. “Kindly take the helm for a moment, Sir Reginald, if you please.”Sir Reginald at once stepped to the tiller and laid his hand on it. “Where am I to steer for?” he asked.“Head for the liner, in the first instance,” answered Mildmay, as he threw the self-steering apparatus out of gear; “and then bring the ship’s head very gradually round until you are pointing for the pirate’s stern.”And, so saying, he stepped to the fore midship window of the pilot-house, laid his finger lightly upon the firing-button that controlled the discharge of the torpedo-shells from the tube in the extremity of the ship’s sharp snout, and so placed his eye that he brought the jack-staff forward in a direct line with a very small notch inthe window-frame. He stood thus, rigid and tense, while Sir Reginald did his part of the work; and presently he saw the jack-staff swinging slowly round toward the pirate cruiser. He waited thus until his two sights pointed something less than an eighth of a length ahead of the cruiser, and then he pressed the button hard. As he did so, something flashed like a sudden gleam of sunlight from theFlying Fish’sstem, a sheet of water some four or five yards in length leaped into the air from under the bows, and some six seconds later a blinding flash started out from the side of the cruiser, midway between her stem and her foremast. As the flash disappeared, Lethbridge, who was watching the ship through his binoculars, saw a great black patch on the cruiser’s side, exactly where the flash had occurred; and while he was still wondering what it could mean he became aware that the craft was rapidly settling by the head. And before he could sufficiently recover from his astonishment to utter a word, the cruiser’s bows sank to a level with the water, her stern rose high in the air, with the propeller still spinning round, and in another second she dived forward and disappeared, with the black flag still fluttering from her main truck.

When, having reached the dining-room of theFlying Fish, Mildmay changed out of his diving-suit into his ordinary clothes, it was found that he was so severely bruised and strained that the professor, in his capacity of emergency medical adviser to the party, insisted upon his immediate retirement to his cabin and his bed. There the worthy man subjected him to so vigorous a massage, and so generous an anointing with a certain embrocation of his own concocting, that two days later the genial sailor was again able to be up and about. And, meanwhile, Sir Reginald and Colonel Sziszkinski continued the examination of the wreck, but unfortunately without any satisfactory result; for although they succeeded in finding the captain’s cabin, and bringing therefrom, and from some of the other cabins, a considerable number of documents, it was found that, owing to their long submersion, they had become so completely sodden that any attempt to handle them, while still wet, reduced them to pulp; and when the alternative of carefully drying them was tried, they became so exceedingly brittle that they simply crumbled to pieces, while, even on the fragments that they contrived to preserve, the writing was so nearly obliterated as to be quite undecipherable. Nevertheless, they preserved as much as they could, in the hope that the experts in such matters, at home, might be more successful than themselves. But it may here be stated that the experts also failed; and the name and nationality of the ship, as well as the identity of those who perished in her at the murderous hands of the savage M’Bongwele, remain a mystery to this day.

On the third day following Mildmay’s adventure with the octopus, theFlying Fishbeing once more berthed on the beach near the spot where the party had made their amazingly rich haul of rubies, all hands had adjourned to the deck after dinner to enjoy the delicious coolness of a breeze off the sea. Ida had gone to bed somewhat earlier than usual that evening, complaining that she was not feeling very well, her symptoms being a feverish pulse and a slightly increased temperature, toward the alleviation of which the professor had administered a fairly liberal dose of quinine.

Sir Reginald and Lady Olivia, naturally anxious in everything relating to their only child’s health, were discussing the matter with von Schalckenberg, who was endeavouring, without his usual success, to reassure the pair, who were of opinion that the African climate was to blame for their daughter’s indisposition.

“Well,” at length said the professor, “if you really think so, nothing in this world is easier than for us to change it. We can ascend into the atmosphere to any height we please, thus obtaining any desired temperature; we can, in a veryfewhours, reach any other country that you would care to visit; or, which is perhaps better than either, we can go out to sea and leisurely cruise about in any required direction, and in absolutely pure air.”

“Hear, hear!” exclaimed Mildmay, who, although chatting with Mlle. Feodorovna, had overheard the professor’s words. “There is no sanatorium like old ocean; no doctor like Father Neptune, believe me, Elphinstone. A week’s cruise somewhere away out there to the eastward would set the little darling up far more effectively than all the professor’s drugs. Try it, man; it can do no harm; and I’ll bet you a—a—well, let us say a peck of rubies, that you’ll not regret it.”

“Well, while declining your modest little bet, Mildmay, I really feel more than half inclined to act upon your suggestion,” answered Sir Reginald, with a laugh. “There is no particular reason why we should not, I fancy, beyond the fact that the professor wants to shoot one or two of those new zebras, and we can easily return here for that purpose. The fact is that I am beginning to tire a little of shore life, and I think a trip out to sea would do us all good. What do the rest say?”

“So far as I am concerned I will gladly go anywhere, or do anything, for Ida’s sake,” answered Lethbridge.

“Thanks, old chap; I know you will,” said Sir Reginald. “What say you, Colonel?”—to Sziszkinski—“would you like to go with us, or would you prefer to remain here until our return, and go in for shooting under the aegis of our friend Lobelalatutu?”

“Thank you very much, Sir Reginald, for offering me the choice,” answered the Russian. “I prefer to accompany you. I am quite of your own opinion, that a change will do us all good; and, like my friend, Monsieur Lethbridge, I will gladly go anywhere and do anything for the sake of the charming little Mademoiselle Ida.”

“And you, Mademoiselle?” asked Sir Reginald, turning to Mildmay’s companion.

“I?” she answered. “Oh, Monsieur Edouard—Sir Reginald, I mean—I am so happy on board this beautiful ship that I feel I shall never want to leave her. Please accept papa’s answer as mine also.”

“I am really very much obliged to you all for so cheerfully and readily falling in with my wishes,” said Sir Reginald. “Very well, then; it is settled that we go to sea for a week or two, as the mood takes us. Now, the next question is, Where shall we go? We certainly ought to have some definite objective, don’t you think? Does any one desire to go anywhere in particular?”

There was silence for a minute or two. Apparently no one wished to go anywhere in particular; or, if they did, they were not sufficiently eager to feel called upon to mention the fact.

At length Lady Olivia looked up.

“Has nobody a suggestion to make?” she asked, with a smile. “Then I will make one that I think will be sympathetically received by at least one of us—yourself, my dear Feodorovna. I have long had the wish to possess a really fine set of pearls, not the kind that one can go into any jeweller’s shop and buy, you know, but something quite out of the common; and it appears to me that this voyage of ours affords just the opportunity for somebody to fish those pearls up for me from the bottom of the sea. And I dare say that your papa—or somebody else—would be quite willing to do the same for you, dear. What do you say?”

“What do I say?” repeated the lovely young Russian. “Why, that I simply adore pearls.”

“Then, I think, Reginald, that you have your answer,” said Lady Olivia, turning to her husband.

“All right, dear,” he answered. “Pearl-fishing will suit me down to the ground; and if the ocean holds pearls enough to satisfy you, you shall have them. Now, Professor—Mildmay—where must we go in order to get those pearls? For, of course, we must go to some definite spot to look for them; we can’t go grubbing along the sea-bottom at random until we happen to stumble upon a bed of pearl-oysters, you know.”

“The most famous pearl-fishing grounds are situated in the Persian Gulf and off the coast of Ceylon,” answered Mildmay. “And I believe,” he added, “that in both cases they are Government property, and strictly preserved. But I have no doubt there are plenty of oyster-beds which are beyond the reach of the ordinary pearl-diver; and it is one of those that we must seek. We shall not be poaching on anybody’s preserves if we do this; and shall also stand a better chance of securing some good specimens.”

“Before you come to any definite decision, I should like to refer to a rather interesting manuscript book that I have in my cabin—the book that I recovered from the sunken wreck of theDaedalus, under circumstances which, perhaps, yet remain in your memory,” observed von Schalckenberg, addressing Sir Reginald. “I seem to remember,” he continued, “having come across a passage in it relating to a bed of pearl-oysters of immense value, the situation of which was then unknown to any one except the writer. If you will excuse me a moment, I will go and fetch it.”

“By all means,” said Sir Reginald. “From what you say, Professor, it would appear that the bed to which you refer is the identical one we want to find.”

The professor accordingly retreated; and presently returned with a small, leather-bound, and much discoloured book in his hand. His forefinger was between the pages, and he opened the book there.

“Yes,” he said, “I thought I was not mistaken. Here is the passage, under the heading of ‘Pearls. In Longitude 155 degrees 32 minutes 17 seconds East, and exactly under the Equator, there exists a small atoll, unnamed, and, I believe, unknown, unless it be to the natives of Matador and Greenwich Islands, which are in its neighbourhood. The islet, which is uninhabited, is little more than a mere rock, about a quarter of a mile long, and some fifty feet wide, over which the sea makes a clean breach in heavy weather; but the lagoon is about five miles long and three miles wide, with good anchorage for ships in a pretty uniform depth of ten fathoms. Two miles due west of this island there is a shoal, some seven miles long, by from two to four miles wide, with twenty-eight feet of water over it. And this shoal is almost entirely covered with pearl-oysters, yielding some of the finest and most perfect gems that I have ever seen.’ Now, what think you of that, my friend. Is that good enough for you?” demanded the professor.

“Quite good enough,” answered Sir Reginald. “Now, skipper,” he continued, turning to Mildmay, “how far off is this famous oyster-bed, and how long will it take us to get there?”

“What did you say is the position of the spot, Professor?” asked Mildmay.

The professor restated the longitude.

“Um!” observed Mildmay, figuring upon a piece of paper that he drew from his pocket; “it is a goodish step from here to there! roughly, about seven thousand miles, as the crow flies. As to how long it will take us to get there; we can do the distance in sixty hours, by going aloft into the calm belt, shutting ourselves in, and going full speed ahead. Otherwise—”

“Thanks, very much; and never mind the ‘otherwise,’” answered Sir Reginald. “This is going to be aseatrip; and we are going to do at least a part of it in leisurely fashion, say, about ten to fifteen knots an hour. When we are tired of that, and at night, we can go aloft and put on the speed if we wish. And, now that I come to think of it, is there any reason why we should not start at once?”

No one, it appeared, had any reason to advance against the baronet’s proposal. Accordingly, he and Mildmay forthwith adjourned to consult the chart and lay off the course; and ten minutes later the remainder of the party, who were still sitting on deck, awaiting the return of the absentees, became conscious of the fact that the night-breeze had suddenly strengthened; and when they looked about them in search of an explanation, they saw the sea about three hundred feet beneath them, and the land slipping away into the gloom of the night astern.

The travellers had been at sea a week, pottering along on the surface during the day, and rising some three hundred feet into the air at night—just high enough, in fact, to take them over and clear of the masts of any ships that they might happen to encounter during the hours of darkness—maintaining a tolerably uniform speed of ten knots through the air—not counting the acceleration or retardation of speed due to the varying direction and strength of the several winds that they met with. Thus they had been able to sleep at night with wide open ports, to their great comfort and enjoyment, and the manifest improvement of their health, as was particularly exemplified in the case of little Ida, who was by this time as well as even her parents could desire.

The hour was eleven o’clock in the forenoon—six bells, Mildmay called it—and the ship had been running on the surface for about an hour. The entire party were sitting out on deck under the awnings, amusing themselves in various ways, the two ladies, each with a book on her lap, to which it is to be feared she was giving but scant attention, and Ida, her father, Lethbridge, and the Russian colonel playing bull. It was a most lovely day, the sky without a cloud, the water smooth, and a soft but refreshing breeze was breathing out from the southward. The ship was steering herself, the self-steering apparatus having been thrown into action, as no other craft were in sight.

The horizon was not to remain bare for very long, however; for just as Mildmay rose to his feet with some idea of going below, the dull, muffled boom of a distant gun was heard, and, everybody at once looking round the horizon in search of the source of so very novel an occurrence, the topmast-heads and smoke of a steamer were seen just showing above the ocean’s rim, about three points on the starboard bow. She seemed to be in a hurry, too, if the dense volumes of smoke that poured from her as yet unseen funnels were to be taken as any criterion.

“Now, what craft will that be?” exclaimed “the skipper,” as he studied the two mastheads attentively. “A liner, I should say, by the length of her between her masts. Probably an ‘Orient,’ ‘Orient-Pacific,’ or ‘X. and Z.’ boat. But surely she did not fire that gun? And, if she did not—oho! what is this? There is another craft astern of her! I can just make out her mastheads rising above the horizon. Now, did number two fire that gun; and, if so, why? I must get my glasses; this promises to be interesting. And we shall see more of it presently; they are crossing our hawse in a diagonal direction, and edging this way.”

The game of bull was forthwith abandoned, as being of much less interest than the advent of two strange ships on the scene—for, singularly enough, these were the first craft that they had sighted since leaving the African coast—and everybody at once made a dash below for his or her own especial pair of binoculars.

The two strange craft were coming along at a great rate, and rising above the horizon very quickly; thus, by the time that Mildmay returned to the deck with his glasses in his hand, the leading ship was almost straight ahead, and had risen sufficiently to show her chart-house above the horizon, and to enable “the skipper” to see that she carried a wheel-house on top of the fore end of it, and a short awning abaft the wheel-house.

“Yes,” he muttered to himself, “she is a liner, undoubtedly; and an X. and Z. boat at that, unless I am greatly mistaken. Two masts—the mainmast stepped a long way aft; and two funnels amidships, pretty close together—yes; she is an X. and Z.; I’ll bet my hat on that. And she is steaming for all she is worth. I can see the ‘white feather’ blowing away from the top of her waste-pipes. Now, is she racing with that other chap; or—is she running away from him?”

He turned his binoculars upon the sternmost ship, which was also coming along at a great rate, and gradually lifting above the horizon. About half the length of her masts—two of them—was now showing; and as Mildmay focussed his lenses upon them an ejaculation of astonishment escaped his lips.

“A man-o’-war, by the Lord Harry!” he exclaimed. “Yes; there are her upper signal-yards, and her fighting-tops below them, clear enough. By the piper, this is growing interesting indeed. Now, who and what is she? and why is she chasing a British liner?—for sheischasing her, beyond a doubt!”

“Well, Mildmay, what do you make of them?” inquired Sir Reginald, as he at this moment stepped out on deck.

“I make of it,” answered Mildmay, “that the leading ship is an X. and Z. liner steaming for all she is worth; and that the second ship is a man-o’-war—a second-class cruiser, I should say—chasing her!”

“The dickens you do!” returned Sir Reginald. “Then what does it mean? Is it not something rather unusual?”

“It is so extremely unusual, that I am going to ask your permission to haul up a point or two, presently, that we may investigate the matter,” answered Mildmay. “There is only one possible explanation of it; and that is that war has quite suddenly broken out between England and some other Power. And yet that can scarcely be, either; for when we left home everything was quite quiet; the political horizon was as clear as it ever is, and—dashed if I can understand it. But anyhow, Elphinstone, I suppose we are not going to jog quietly along and see a British ship bullied by a foreigner without having a word or two to say about it, are we?”

“Not much!” answered Sir Reginald, emphatically, and with a flash of the eye that delighted Mildmay. “I know nothing of these matters,” he continued, “or how to proceed; but you do; so take charge, old chap, and give us your orders. We will obey them to the letter, I promise you.”

“A thousand thanks,” answered Mildmay. “Of course I need not tell you that to interfere in a case of this kind, with no knowledge of the facts, is a somewhat ticklish business. But, all the same, that is not going to stop me. I see, yonder, a British ship flying from a stranger; and with your kind permission I am going to lend her a hand.”

He raised his glasses to his eyes again. The hull of the leading ship had by this time almost topped the horizon, and it was now possible to see something of her shape. She was a fairly big craft, measuring, according to Mildmay’s estimate, about eight thousand tons; and her whole shape and appearance confirmed him in his original conviction that she was one of the X. and Z. Company’s boats. She flew no flag at her masthead, it is true; but Mildmay could now see that she had hoisted a blue ensign on her ensign staff.

“Under the command of a R.N.R. man,” he commented, as he saw this. “All right, old man; there is a friend within a few miles of you, whose proximity you probably don’t suspect; and we will see that you don’t come to any harm. Now let us have a look at t’other chap.”

The second craft was still hull-down; but her masts, funnels, tops of her ventilators, and the head of her ensign staff were all visible; and Mildmay noticed that she was showing no colours. This fact rendered the whole affair more puzzling than ever; for there could be no possible doubt that she was chasing the liner, and for a man-o’-war openly and undisguisedly to chase another ship, and not show her colours, was unprecedented, and most certainly not in accordance with any recognised rule of warfare.

Meanwhile, the rest of the party had come on deck, and were all intently watching the two ships through their binoculars as they animatedly discussed the puzzling situation.

“When do you intend to haul up, ‘skipper’?” asked Sir Reginald.

“Not yet,” answered Mildmay. “Perhaps in about ten minutes’ time—unless anything occurs of a character that would make it desirable to do so earlier. I want to see a little more of the game first.”

“Then there you have it!” exclaimed Lethbridge, as a flash, followed by a puff of brilliant white smoke, issued from the bows of the pursuing ship.

A jet of foam leaped up from the surface of the sea, about half a mile astern of the liner, and dissolved like steam in the dazzling sunshine. Then the boom of the gun came floating down to the ears of the watchers.

“A four-inch, by the sound of it,” remarked Mildmay. “And shotted, too. Clearly, the fellow is in earnest, whoever he may be. Now, what the dickens is the explanation of this enigma? And what is the nationality of the craft?”

“Can’t you tell by the build of her?” demanded Lethbridge. “I have always understood that you sailors had but to look at a ship to tell her nationality at once; at least that is the impression that one gathers from the general run of sea novels.”

“Yes,” answered Mildmay. “But that refers to the old days of wooden ships. There was a distinctiveness in the model of the wooden ship that was an almost infallible index to her nationality. But nowadays ships—and particularly war-ships—are built so much alike in shape that, except in a few rather extreme cases, it is practically impossible to identify them. That fellow, yonder, for instance, might be British, Dutch, German, Austrian, Italian, or Japanese, for all that one can tell by merely looking at him. Ah, there goes another gun!”

The shot this time struck somewhat nearer, throwing up three successive jets of water, the last of which appeared to be unpleasantly close to the stern of the chase.

“The fellow is overhauling her,” exclaimed Mildmay. “Now, Elphinstone, with your permission, I will shift our helm and alter our course forty-five degrees to the nor’ard.”

And, so saying, he entered the pilot-house; and a moment later the watchers saw the two distant craft swing back along the horizon until the leading ship bore two points on theFlying Fish’sstarboard bow.

“If you have no objection, Sir Reginald, I should like a torpedo-shell put into our bow tube,” observed Mildmay, as he emerged from the pilot-house.

“Certainly,” answered Sir Reginald; “I will go below and put one in at once.”

“Better let me do it,” interposed the professor. “I know more about the working of them than you do; and, moreover, I am not so profoundly interested in this affair as you all seem to be. Besides, I shall not be gone longer than five minutes at the utmost.”

And, Sir Reginald offering no objection, the worthy man turned away and vanished through the pilot-house door.

The leading ship was by this time within about five miles of theFlying Fish, and steering a course that would take her square across the bows of the latter; the two—or, indeed, the three—ships were therefore nearing each other fast, and the men fell to debating the question whether or not theFlying Fishhad yet been seen by either of the strangers. The craft was in her usual surface-running trim; that is to say, considerably more than half of her polished hull was submerged, leaving little to be seen except her small superstructure and her pilot-house, both of which were painted a delicate blue-grey colour that would be scarcely visible against the horizon astern. The chances, therefore, were strongly in favour of her invisibility. On the other hand, there was just a possibility that some keen eye aboard the liner, anxiously scanning the horizon in quest of help, might have sighted her; in which case a glimpse of the white ensign might be comforting. Mildmay therefore went to the flag-locker and drew forth the white ensign which, in virtue of his being a member of the Royal Yacht Squadron, Sir Reginald was entitled to fly, and ran it up to the truck of the ensign staff.

Whether it had been seen or not was difficult to say, for nothing in particular followed upon its exhibition, unless the discharge of another gun from the pursuing ship might be taken as a reply. And this time the shot went home to its mark; for as the observers turned their glasses upon the chase, her mainmast was seen to totter and fall by the board, cut short off by the deck. Luckily the spar did not go over the side, but lay, fore-and-aft, inboard; otherwise the rigging might have fouled the propeller and brought the ship to a standstill. As it was, she continued her flight as though nothing had happened.

“This matter has gone quite far enough,” exclaimed Mildmay, sharply, as he saw the liner’s mast fall. “Come inside, all of you, if you please. We may be under fire in another minute or two. Perhaps the ladies had better go below until this affair is settled—if you will be so kind,” he added, with a bow to Lady Olivia as she passed in through the pilot-house door, outside which he was standing.

When all the rest had entered, he followed, closing the door behind him, and at once ascended to the working chamber of the pilot-house, whither Sir Reginald and Lethbridge had preceded him. His first act was to increase the speed of theFlying Fishto thirty knots; and as he moved the lever forward, admitting a larger flow of vapour to the engine-cylinders, Lethbridge, who was standing at one of the windows, with his binoculars to his eyes, turned and said—

“What do you think of that, Mildmay?”

“What do I think of what?” retorted Mildmay, stepping to his side.

“That!” answered Lethbridge, pointing to the pursuing ship and handing over his glasses for the other to use. “The unknown has just hoisted to her masthead a black flag with a white skull and cross-bones in its centre. Is not that—?”

“Nonsense!” exclaimed Mildmay. “You surely do not mean it. Let me have a look.”

He raised the glasses to his eyes for a moment and stared through them as though he felt that he could scarcely credit the evidence of his own senses. Then, as he thrust the glasses back into his friend’s hand, he exclaimed—

“The ‘Jolly Roger,’ as I am a living sinner! Well, that ‘takes the cake,’ and no mistake! Yes; the fellow is undoubtedly a genuine, up-to-date, twentieth-century pirate. If it had not been for that last shot I might have been inclined to believe the whole affair an elaborate joke in the very worst taste; but a man does not shoot another fellow’s mast away as a joke. No; that chap means business—and so doI! Ah, another shot! and—yes, here it comes—he is firing at us! Not at all badly aimed, either.”

As he spoke the loud rushing sound of the shot broke upon their ears; and a moment later it struck the sea about three yards astern of theFlying Fish, sending a column of white, steam-like foam and spray shooting some twenty feet into the air. Almost instantly another shot followed, which, judging from the sound, must have passed close over the pilot-house roof; to be followed, a few seconds later, by a third, which struck the water within a fathom of the ship’s sharp nose, which was just level with the water’s surface, and, owing to the speed of the ship, was sending up a fine, perpendicular jet of glassy water some ten feet high.

“Confound the fellow’s impudence!” exclaimed Sir Reginald. “Does the rascal think that he is going to make a prize ofus? A fine rich prize we should make, too, did he but know it!”

“It is not that,” explained Mildmay. “It is the white ensign that he doesn’t like the look of. He probably takes us for some new-fangled sort of British gun-boat, bent upon interfering with his little game; and he wants to disable us. He is one of those pestilently persistent fellows who won’t take a hint and sheer off; he is as full of obstinacy as was the mammoth that chased me over yonder,”—with a jerk of his thumb toward the north—“on our first trip, and must be treated as we treated that mammoth. For if we don’t kill him, he will kill us—if he can. You see? Here comes another shot!”

It was a very close shave that time, the missile passing so close athwart the front of the pilot-house that its wind actually came, in a sudden, violent gust, in through the pilot-house window.

“We must put a stop to this at once, or the fellow will do us a mischief,” exclaimed Mildmay. “Kindly take the helm for a moment, Sir Reginald, if you please.”

Sir Reginald at once stepped to the tiller and laid his hand on it. “Where am I to steer for?” he asked.

“Head for the liner, in the first instance,” answered Mildmay, as he threw the self-steering apparatus out of gear; “and then bring the ship’s head very gradually round until you are pointing for the pirate’s stern.”

And, so saying, he stepped to the fore midship window of the pilot-house, laid his finger lightly upon the firing-button that controlled the discharge of the torpedo-shells from the tube in the extremity of the ship’s sharp snout, and so placed his eye that he brought the jack-staff forward in a direct line with a very small notch inthe window-frame. He stood thus, rigid and tense, while Sir Reginald did his part of the work; and presently he saw the jack-staff swinging slowly round toward the pirate cruiser. He waited thus until his two sights pointed something less than an eighth of a length ahead of the cruiser, and then he pressed the button hard. As he did so, something flashed like a sudden gleam of sunlight from theFlying Fish’sstem, a sheet of water some four or five yards in length leaped into the air from under the bows, and some six seconds later a blinding flash started out from the side of the cruiser, midway between her stem and her foremast. As the flash disappeared, Lethbridge, who was watching the ship through his binoculars, saw a great black patch on the cruiser’s side, exactly where the flash had occurred; and while he was still wondering what it could mean he became aware that the craft was rapidly settling by the head. And before he could sufficiently recover from his astonishment to utter a word, the cruiser’s bows sank to a level with the water, her stern rose high in the air, with the propeller still spinning round, and in another second she dived forward and disappeared, with the black flag still fluttering from her main truck.
