The afternoon's work was rewarded by the discovery of two medium-sized and two small stones of very fine fire and colour; and the second day's labour resulted in a find of five fine and eight medium-sized stones.

Thus the toilers progressed, each day yielding them a better return for their labour, until late in the afternoon of the fifth day they struck the "pocket," so confidently looked for by the professor. Then the gems were found in such abundance that it was scarcely possible to turn over a shovel-full of soil without finding one or more; while it was by no means uncommon to turn up as many as half a dozen at one stroke of the shovel. This extraordinarily prolific yield lasted for no fewer than four days, during which they acc.u.mulated such an enormous quant.i.ty of gems--practically every one of which was of exceptional value--that at length, although the mine was very far from being exhausted, even the professor declared himself satisfied, while Colonel Sziszkinski found himself suddenly relieved of a very heavy load of anxiety by the acquisition of a sufficient number of valuable gems to yield him a very handsome fortune if discreetly placed upon the market.

"That, I suspect, will be your difficulty, Professor; you will be so anxious to realise that you will flood the market, and cause a big depreciation in the value of rubies," remarked Lethbridge, rather caustically, when after their last day at the mine they met again at the dinner-table.

Von Schalckenberg laughed. "I will take my chance of that, my friend,"

he replied. "But have no fear; I will not flood the market, or lower the value of rubies. There are plenty of people who are always ready to buy fine stones--when they get the chance, which is not often; and I have a friend in Amsterdam whose knowledge of the market is second to none in the world. I shall put my rubies into his hands to sell, and he will know how to dispose of them without flooding the market. You had better let the same man have yours, Boris, my friend. What do you think of doing with yours, Sir Reginald?"

"I?" returned Sir Reginald. "Oh, I shall pick out the finest, and have them cut and set as a suite for Lady Elphinstone; and, as for the rest of them--well, I don't quite know what I shall do with them. But, anyhow, I promise you that I will not put them on the market early enough to spoil the sale of your stones."

"Ah!" exclaimed the professor, appealing to the company at large; "see what an advantage it is to be a rich man. What do you propose to do with yours, Lethbridge?"

"Oh, I don't know," answered the ex-colonel; "follow Elphinstone's example, I think, and have a suite made for this young woman," pinching Ida's cheek, "against the time when she is old enough to get married; and--perhaps sell the rest some time or other."

The professor glanced inquiringly at Mildmay.

"I think I, too, will have a suite made," observed the sailor; "it seems rather a good idea. Pretty sure to come in handy, sooner or later."

And his eyes turned, as though unconsciously, in the direction of Feodorovna Sziszkinski, to the confusion of that young lady, and the covert amus.e.m.e.nt of Lady Olivia.

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, the _Flying Fish_ rose 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 doc.u.ments, 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, the _Flying Fish_ was 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 a.s.suming 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 pa.s.sage 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, _one_ to 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 the _Flying Fish_--they were able to see with tolerable distinctness, even without the a.s.sistance 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 pa.s.s 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 antic.i.p.ated, merely the after part of the ship, the remainder doubtless lying on the other, or insh.o.r.e, 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 circ.u.mstance 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 inst.i.tute 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 a.s.sistance."

"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 the stern 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 s.n.a.t.c.hed 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 rea.s.sured, 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 it _was_ amusing to him to think of the creature's disappointment at its utter inability to pierce his sh.e.l.l 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 s.p.a.ce 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 s.p.a.ce 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 pa.s.sed 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 pa.s.sage 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 pa.s.sed, 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 a.s.sistance. 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 pa.s.sage 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 inst.i.tuting 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 the _Flying Fish_, Lethbridge, intent upon making the time pa.s.s 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 amus.e.m.e.nt 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-gla.s.s 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 rea.s.sured.

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 ma.s.s and stand for some few minutes, evidently in consultation; and finally they saw one of them climb up the wreck and then a.s.sist 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 ident.i.ty, 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 ident.i.ty. 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 quant.i.ty 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 had _not_ seen. 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?"

Evidently _she_ had 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.
