An anchor watch was kept that night as a precautionary measure, because it was not then known whether the group was inhabited or not; but nothing occurred to alarm the watchers, the only sounds heard being those made by the countless insects on sh.o.r.e or the weird cries uttered by the nocturnal birds. Some of the sounds and cries were certainly uncanny enough to send a creeping thrill through the frame of the listener, but with that exception the night pa.s.sed peacefully away; and when the hands were turned up next morning to wash decks many was the longing glance which was cast across the water to the bosky glades, which looked so inviting in the bright sunshine.

Williams' alert eye at length took cognisance of these longing glances, and when at length the task of washing down was completed, the buckets and scrubbing-brushes put away, and the running-gear hauled taut and coiled down, he summoned the men into the waist, and informed them that, prior to beginning upon the somewhat lengthy task which he intended to carry through before again leaving the anchorage, he proposed to have the islands thoroughly explored and examined, the exploration to partake somewhat of the nature of a holiday ramble ash.o.r.e, when each man, properly armed, would be at liberty to go whithersoever he would, and to spend the day pretty much as he pleased, so long as the question of whether the group was inhabited or not was satisfactorily settled. And he further intimated that that same day would be devoted to the examination; an intimation which was received with enthusiastic cheers.

Upon hearing this announcement Ned--who for reasons of his own was most anxious to keep on fairly good terms with all hands, and especially to so shape his conduct as to remove any suspicions against him which might still be lurking in the minds of the mutineers--at once stepped forward and, stating to Williams his desire to take part in the exploration, requisitioned the dinghy for his own and Miss Stanhope's use. His request was favourably received, and acceded to with a prompt.i.tude which somewhat surprised him; whereupon he hastened into the saloon, and, encountering the steward, gave orders for the preparation of a substantial luncheon basket, after which he apprised Sibylla of his proposed expedition.

Accordingly, as soon as breakfast was over, the two young people set off in the dinghy, Sibylla being seated in the stern-sheets, with the yoke- lines in her hands and the lunch basket at her feet, whilst Ned faced her, handling the diminutive oars--or "paddles," as the seamen termed them--without an effort. That he had not been unmindful of possible dangers was evidenced by the fact that that he had recommended Sibylla to take with her both her revolvers and a goodly supply of ammunition, whilst, as for himself, he was a perfect walking battery, a pair of revolvers and a small hatchet being stuck into his ammunition belt, whilst a ship's carbine reposed peacefully in the bows on the coiled-up painter of the boat.

Early as Ned and Sibylla were in leaving the ship, the mutineers had got the start of them, and, observing that the rest of the boats were making for the east and south islands, Ned determined to give them a wide berth, and accordingly paddled away for the north island, which was the largest in the group. He headed for a small strip of sandy beach which he had noticed during the examination of the harbour on the previous day, and after a leisurely pull of more than an hour across the placid waters of the basin beached the boat.

Ned was by nature a keenly observant young gentleman, and the first fact which attracted his attention on landing was that the water in the basin was at exactly the same height on the beach as when they had pa.s.sed it some hours later on the previous day, from which he at once arrived at the conclusion--afterwards proved to be correct--that there was practically no tide in Refuge Harbour, as Williams at once named the place. But to obviate all possibility of the dinghy being swept away he not only dragged her half her length up high and dry upon the beach, but also planted one of the paddles firmly in the sand and then made fast the painter to it. This done, the lunch basket was stowed carefully away in the shade under the stern-sheets, when, loading and shouldering his carbine, Ned strolled along at an easy pace, so that Sibylla could walk beside him without much apprehension, the beach nowhere showing any footprints, as Ned believed it surely would have done had the place been inhabited.

They struck directly inland, and after traversing the narrow bit of sand reached the green-sward, the thick, luxuriant gra.s.s on which reached almost up to their waists. The ground here was open, the clumps of trees which they had noticed from the ship--and which now seemed to be as it were the outposts of a dense forest--not approaching in this particular spot nearer than about a quarter of a mile of the water. But even here there was enough and more than enough to occupy their pleased attention for the moment, the long gra.s.s being thickly interspersed with flowering plants and shrubs, adorned with blossoms of most exquisite form, hue, and fragrance. Sibylla, woman-like, must needs at once proceed to gather a bouquet for herself, in which pleasing occupation the next half-hour was spent. And here the pair were somewhat startlingly reminded that there is no Eden without its serpent, for as Sibylla stooped over a shrub loaded with magnificent white azalea-like blooms, one or two of which she desired for the completion of her bouquet, a sharp hissing sound was heard, and she started back with a cry, just in time to avoid a vicious stroke from a small heart-shaped head which suddenly upreared itself from among the leaves of the plant.

Ned, however, was close beside her, and whipping out his revolver he fired, blowing the head of the snake clean off.

"Did the creature strike you?" demanded Ned anxiously.

"No," answered Sibylla; "I was so startled at its sudden appearance and its malignant aspect that I darted back without giving it time to bite.

Do you think the creature was venomous?"

"We will soon see," answered Ned; and searching about in the long gra.s.s, which he was careful to divide with the barrel of his carbine, he soon found and held up to his companion's horrified view the severed head.

"Yes," he announced, "the brute was undoubtedly venomous. Note the heart-like shape of the head, the heads of all venomous snakes are shaped more or less like that. And see here," he added, compressing the neck just behind the jaws in such a way as to force the mouth open, "do you observe these two curved needle-like fangs, one on each side of the upper jaw? Those are the poison fangs. And these swellings of the gums at the base of the fangs are the poison bags. They become compressed when the fangs strike into the flesh of a victim, and a drop or two of the venom pa.s.ses down through the fang, which is hollow, into the wound, and thus the mischief is done. You have had a narrow escape, Miss Stanhope."

After this little adventure the wanderers conducted their perambulations much more circ.u.mspectly, and Ned lost no time in providing his companion and himself with a stout pliant switch, which he had heard or read somewhere is a most effective weapon against snakes.

Soon after this they reached the outskirts of the forest, and it was not long before Ned discovered in a little greed patch of sward a small grove of banana trees with huge bunches of fruit, more or less ripe, depending from the crown of immense palmate leaves. He saw that the trees were of two or three different kinds, and, looking more closely, he quickly discovered that of which he was in search. Then, approaching one of the trees, he reached up and dragged the bunch of fruit down toward him, and, detaching several of the bananas, which were small and of a fine yellow colour, he approached Sibylla, saying:

"Now, let me offer you a treat, in the shape of a few 'ladies' fingers;'

so called, I believe, because the fruit is so small and delicate. I scarcely think you will have ever tasted this kind of banana before, because I believe it will not bear transportation to England without spoiling."

Sibylla tasted the fruit, which she p.r.o.nounced delicious, and then they resumed their ramble, enjoying their bananas as they went. A little further on they found some magnificent pine-apples, then some granadillas, and shortly afterwards several other fruits were met with, a few of which Ned was acquainted with, whilst others he had never seen before, and these last they very wisely let alone.

When about half a mile distant from the beach they entered the actual forest. Here the trees grew very closely together, whilst the entire s.p.a.ce between their trunks was completely choked with a dense undergrowth of parasitic creepers, the long, thin, pliant tendrils of which stretched from trunk to trunk, or hung in festoons from the lower branches, and were so hopelessly tangled up together that progress was quite impossible, except along and through such openings as were the result of accident. Here the ground was quite bare of gra.s.s, a thick carpet of dry twigs and fallen leaves taking its place, and the whole aspect of the wood looked so exceedingly unpromising that Ned proposed turning back. Sibylla, however, was not so easily discouraged; she was very desirous of reaching the ridge or highest part of the island, and was not disposed to retrace her steps without at least making the attempt. They accordingly once more moved forward, Ned leading the way, and directing his steps as best he could with the aid of a small compa.s.s which he wore attached as a charm to his watch-guard.

They had advanced but a very few yards into this "bush," as Ned termed it, when they found themselves wandering almost blindly in the midst of a deep, sombre, greenish twilight gloom; the overhead growth being so dense as to almost entirely exclude the daylight, save where, here and there, an accidental break permitted a stray sunbeam to stream down and illumine a s.p.a.ce of a few square yards. The effect of these partial illuminations was very beautiful, revealing as they did the long tangled festoons of creepers hanging black and snake-like against the light, and causing the brilliant tints of the variegated foliage and the resplendent hues of the flowers to flash out with dazzling effect against the contrasting shadows. Moreover, these little illuminated patches were alive with huge superbly-coloured b.u.t.terflies, birds of gaudy plumage, and other winged creatures, whose forms were as novel as the combinations of colours which marked their bodies. They were the scene of a perpetual whirl and flutter of wings, and before they betrayed themselves to the sight their locality could be detected by the sense of hearing from the never-ceasing hum and chirp of the insects and the calls of the birds which frequented them. They were the scenes of an eager, busy, active life; whilst in the twilight depths of the forest everything was deathlike, everything was still--the very air was motionless, not a leaf stirred. The silence was weird, oppressive, and awe-inspiring; and when, at more or less lengthened intervals, a dry twig snapped, a withered leaf crackled, when the soft wafting of the wings of some nocturnal bird was heard among the branches overhead, or the sudden, brief rustling which betrayed the presence of some wild creature smote upon the ear, the effect upon the nerves was startling in the extreme. Through these alternate stretches of gloom and brief illuminated s.p.a.ces the pair wound their way, Ned leading and clearing the path where necessary with his axe or his stout, serviceable clasp- knife, until eventually, after more than an hour's toil, they emerged upon a bald, ridge-like eminence which, on looking about them, they found was the highest spot in the entire group.

CHAPTER ELEVEN.

AN IMPORTANT DISCOVERY.

From the point which they had now reached Sibylla and Ned commanded a bird's-eye view of the entire harbour, with South Island--as it soon came to be called--for a background, with the southern horizon showing just clear of its highest portion. Ned was now able to form a very much more correct idea of the entire locality than had before been possible; and as he stood critically examining the two basins, a suggestion as to their possible origin and that of the islands themselves presented itself to his mind. Seen from where he then stood the group bore a very strong resemblance to the crater of a long extinct volcano. To begin with, the ridge-like summits of the islands swept round in a form that was roughly circular, and they would have been continuous but for the breaches or channels which separated the islands from each other. They presented an appearance precisely similar to the rim of a volcanic crater; and the inner and outer slopes of the islands were also strongly suggestive of the inside and outside slopes of a crater. The two basins conveyed the idea of two closely contiguous vents for the subterranean fires, and the channels might very well be breaches in the sides of the crater through which the molten lava had burst its way. And this theory was confirmed by the colour of the water at the seaward extremities of the several channels, which clearly indicated the existence of reefs that might very well have been formed by the outflow. Some of these reefs, it is true, were so deeply submerged that the sea did not break over them at all, at least in fine weather such as then prevailed; this being notably apparent in the case of the channel by which the _Flying Cloud_ had entered the harbour. But the mouth of the north-east channel, and that of the north arm of the south-east channel, were so choked with rocks close to the surface that they showed nothing but a wide expanse of white water. In a word, the more Ned thought about it the more convinced he became that he was standing on the summit of a volcanic mountain, the top only of which rose above the surface of the sea. As to the period when the volcano had become extinct, Ned was not scientist enough to form any opinion, but the whole aspect of the place was such as to convince him that it must have been countless ages ago.

Having at length satisfied their eyes with the superb prospect which lay spread out before them and beneath their feet, the happy wanderers--for happy they somehow were, notwithstanding all the unpleasant peculiarities of their position--set out to retrace their steps, reaching their boat about an hour later; when, taking advantage of the shade afforded by a few bushes which grew on the edge of an overhanging bank, they seated themselves on an outcropping rock and did the fullest justice to the luncheon which the friendly steward had put up for them.

It was two o'clock in the afternoon by the time that this meal was disposed of, when Sibylla expressed a desire to have a nearer view of the lofty cliffs bounding the outer basin than she had been able to obtain on the previous day when the ship entered the harbour. The boat was accordingly got afloat and leisurely pulled by Ned close along the northern sh.o.r.e. In due time the dinghy pa.s.sed between the northern and southern bluffs and entered the outer basin, the water being still smooth enough to allow of her keeping within oar's length of the sh.o.r.e; and now they began to realise the majestic and indeed terrific character of the nearly vertical rocky walls which shot sheer out of the water and towered far away above their heads. The qualifying word "nearly" is used advisedly in speaking of the vertical rise of these cliffs, because, whereas when they were pa.s.sed in mid-channel they had the appearance of being absolutely perpendicular, it was now seen that they had a slight--a very slight--backward slope.

The faces of these cliffs were, as has before been stated, so densely clothed with vegetation, mostly in the form of thick-growing shrubs-- though trees of quite respectable size were by no means wanting--that but little of the actual rock was to be seen; and here and there among these shrubs and trees monkeys could be seen swinging from bough to bough, whilst thousands of birds darted in and out and flitted to and fro among the branches. One of these latter at length so strongly attracted Sibylla's admiring attention that she pointed it out to Ned.

"By George!" the lad exclaimed rapturously, "that is a beauty, and no mistake; I must have him. I have long been intending to make a collection of tropical birds for my father, and I might as well begin now; it seems to me that I shall have an opportunity of making a very respectable collection here whilst the mutineers are busy carrying out their plans at the head of the basin."

"You speak as confidently as though you deemed it an absolute certainty that you will eventually succeed in making your escape from those wretches. Do you still regard the project as a hopeful one?" said Sibylla inquiringly.

"Yes, most certainly," answered Ned, as he carefully withdrew the bullet from his carbine, and subst.i.tuted for it a charge of small shot. "The fellows are certain to grow careless, sooner or later, and afford us a chance to give them the slip, even if we do not fall in with a man-of- war and get taken. Keep up your spirits, Miss Stanhope; keep up your spirits and your courage, I say, for I am always thinking and planning, and I never mean to rest satisfied until I have taken you out of the hands of those wretches and safe back to England again."

"You are very good to say so, Mr Damerell, nay more than good,"

answered Sibylla frankly, "and come what may, I shall never, _never_ forget your constant watchful care."

"Oh, don't say too much about that," answered Ned cheerfully. "I look upon you almost as a second sister, you know, and I am only doing for you just exactly what I should wish to be done for my sister Eva if she were placed in a similar position to yours. And as long as you are compelled to remain on board the _Cloud_, I hope you will trust me as fully and as implicitly as if I were your brother; it will perhaps make you feel less lonely, you know, if it serves no other good purpose. And now, where is my bird? I am quite ready for him."

The creature was still hopping about among the branches of a tree almost directly overhead, apparently feeding on the fruit or berries which it found there; and taking careful aim, Ned fired. The report of the carbine went echoing back and forth between the cliffs in the most astounding manner, raising a tremendous disturbance, not only by its reverberations along the cliffs on both sides of the basin, but also from the cries of the countless startled birds which suddenly appeared in the air, and the excited chattering of the equally startled monkeys.

As the smoke from the piece blew away, Ned saw his quarry tumbling from branch to branch, and bough to bough, until it finally brought up in a small bush which overhung the water some fifty feet above its surface.

"Killed him, by all that's lucky!" exclaimed Ned joyously. "Now, if you do not mind being left in the boat a moment by yourself whilst I slip aloft there--I will make the painter fast to this sapling so that you may not go adrift--I will secure my prize."

"But will it not be dangerous for you to climb up there?" protested Sibylla apprehensively.

"If I find it so I will not persevere in my attempt," answered Ned laughingly, as he grasped a bough and swung himself up on to a projecting ledge of rock.

For a few yards of the ascent Ned's figure was clearly visible; then, as he ascended still higher, Sibylla caught sight of him only at intervals, and soon afterwards he vanished altogether among the greenery, though his upward progress could still be traced here and there by the swaying of the bushes, but at length this also ceased, and then a dreadful silence and feeling of lonesomeness seemed to enwrap the fair girl as in the folds of a sable mantle. Minute followed minute with painful slowness as it seemed to Sibylla, and _every_ instant she expected to see Ned's outstretched arm appear from the midst of the shrubs clinging aloft there to grasp the body of the bird. But nothing of the sort occurred, and at length, after a long and tedious period of painful apprehension, she ventured to call his name.

No answer.

Sibylla waited a minute or two, and then called again.

Still no answer.

She now became very seriously alarmed, and, quite losing command of herself, called upon him in piteous accents to answer, or if anything had befallen him to give her some sign of his whereabouts in order that she might be guided to his a.s.sistance. Still calling him, she was about to attempt the perilous ascent of the cliff-face in quest of him when she heard him shout, and, looking up, saw him leaning over the edge of a rocky ledge about a hundred feet above her.

"Are you all right, Miss Stanhope?" he shouted. "I thought I heard you call."

"Yes," she replied, steadying her voice as well as she could on the instant. "I am all right, thank you, but I _have_ been calling; you were so long away that I began to fear some accident had befallen you."

"No," he answered back, "I am all right, but I have made a most wonderful and interesting discovery that--However, I will come down."

And suiting the action to the word, he at once began to descend the face of the cliff, not vertically, as he had gone up, but in a diagonal direction, and, as Sibylla thought, at break-neck speed. Ned continued his wild career until he reached the water's-edge, at a distance of perhaps two hundred feet to the westward of the boat, when, from what Sibylla could see of his movements, he appeared to break the bough of a bush in such a manner as to leave the branch dangling from the parent shrub, after which he began to make his way along the cliff-face toward the boat.

A few minutes later he reached the dinghy--minus the bird, by the by, which he had set out to secure--and stepping in at once proceeded to cast off the painter. Then, as he stepped aft and tossed the paddles into the rowlocks, he first got a glimpse of Sibylla's still troubled face.

"I beg your pardon, Miss Stanhope," he said. "I am afraid I have frightened you by my long stay aloft there. The fact is I was so interested in my discovery that for the moment I forgot the flight of time.

"I have made a most curious and important discovery, and one that may or may not be of the utmost value to us. When I started aloft to get that bird--by the bye, where is it? Ah! I see it! and I will have it, too, before I go back to the ship; but I will tell you my story first. I had not made my way very far up the cliff when I came to what looked so very much like a flight of roughly hewn steps running up the cliff-face that I determined to follow the indications, and investigate. I did so, and soon came to the conclusion that, though the step-like projections were just as thickly overgrown as the rest of the cliff-face--showing that they had not been used for years, or possibly generations, they had undoubtedly been wrought out by the hand of man. Pushing the shrubs on one side I had no difficulty whatever in making my way upwards, until I at length came out upon a flat platform of rock, in the outer edge of which were two holes or depressions, some twelve feet apart, which I imagined might have been hollowed out to receive the heels of a pair of sheers, an impression which was rendered all the stronger when, on looking more closely, I discovered a groove terminating in a third hole which I immediately guessed must have been formed to receive the heel of the back-leg. All this is, I suppose, Greek to you; but you will perhaps comprehend me when I explain that sheers are used to a.s.sist in hoisting heavy articles with. The rocky platform is about fifteen feet square, the cliff-face overhanging it above; and at its back part there is a sort of split in the rock about eight feet wide and nearly the same height. I pa.s.sed in through this crevice, and at once found myself in a cave perhaps thirty feet wide and about fifty feet deep. And now comes the strangest part of the affair. It is nearly half full of bales and parcels, with several jars, apparently earthenware, their mouths tied over with what looks like a coa.r.s.e kind of cloth; but everything is so thickly coated with dust and grime that it is quite impossible to guess at the contents of these jars and bales without further investigation.

And in one corner there are stacked up a number of weapons--spears and axes--so rusted and decayed that they may have been there for centuries.

There are also a number of what I took to be shields by the look of them; but they, like everything else, are so coated with dust that I did not touch them. But I must certainly give the place a thorough overhaul, as it may serve us as a refuge and place of concealment at a pinch. Would you like to go up and have a look at the cave and its contents now?"

"I should like it very much, if you think I could climb the stairs,"

answered Sibylla.
