"Yes," a.s.sented the baronet, who next turned to his more distant companions and hailed them with:

"We have had our trouble for nothing, after all. The best thing we can now do is to make our way back to the ship with all speed, when we can renew the pursuit, unless, as seems only too probable, we are about to have our hands full with the coming storm. We have not a moment to lose, I should say; so I would suggest that each of us put his best foot foremost."

"Ay, ay," replied Mildmay, "crowd sail we must; for, unless I am greatly mistaken, we are about to have a regular tornado."

"A tornado!" gasped the professor. "Run--run for your lives; I verily believe _I forgot to moor the ship_!"

Forgot to moor the ship! Could such fatal carelessness be possible? If so, they must indeed run for their lives; for should the storm burst before they reached the ship she would be whirled away over the plain like an empty bladder before the blast, to what distance and with what results it was difficult just then to foreshadow; but among the possibilities which instantly presented themselves to the mind was that of death to the two inmates of the ship, irreparable damage to the craft herself, and four persons left to shift for themselves in the very centre of Africa, with nothing but the clothes they wore, the rifles they carried, and about a dozen rounds of ammunition apiece. The prospect was appalling enough to send a momentary spasm of horror thrilling through the stoutest heart there, but it also at the same time endowed them with a temporary access of almost supernatural energy; and the four men at once started for the ship at a speed which, even at the moment and to themselves, seemed incredible.

The distance they had to traverse was but short, a mere half-mile or so perhaps; but to the runners it seemed, notwithstanding their speed, as though they would _never_ reach their goal. The gra.s.s was long and tangled, and rapid progress through it was possible only by a series of leaps or bounds; any other mode of progression would simply have resulted in their being tripped up at every other step. This, to men unaccustomed to such exercise, was in itself a sufficiently fatiguing process; but in addition to this they had to contend with the stifling heat of the stagnant atmosphere, which had been oppressive enough even whilst they had been in a condition of comparative inactivity; now it seemed to completely sap their strength and cause their limbs to hang heavy as lead about them. Then, too, the air had become so rarefied that it seemed impossible to breathe, whilst the blood rushed to their heads, and their hearts thumped against their ribs until it seemed as though nature could bear the tremendous exertion no more, and that the runners must drop dead upon the plain. Still, however, the men sped on, the portentous aspect of the heavens serving as an effectual spur to their flagging energies. The dark slate-coloured cloud had already reached the zenith, deepening in tint meanwhile until it had grown almost literally as black as ink. Presently a few great drops of hot rain splashed down upon the panting runners; and, as they rounded the end of the bush clump and came within view of the _Flying Fish_, a blinding flash of lightning blazed out from the sable canopy overhead, accompanied by a deafening peal of thunder which rattled and crashed and boomed and rumbled and rolled until its echoes gradually died away in the distance. A perfect deluge of rain almost immediately followed, wetting the runners to the skin in an instant as effectually as though they had been plunged into the sea. This lasted for perhaps ten seconds, during which every object, even to the racing figures of their companions, was hidden from view by the dense volume of falling water.

Then the rain ceased as abruptly as it had begun, the travellers finding themselves at the same instant close to the towering hull of the _Flying Fish_.

"Last man in, close the trap!" gasped the baronet as he dashed up first to the opening in the ship's bottom. The others were only a few yards behind him and heard his command; so he wasted no more time in conversation, but bounded up the long spiral staircase leading to the pilot-house, having reached which he laid his hands upon the engine lever and tiller, and gaspingly awaited the signal shout which should tell him he might move the ship, gazing anxiously out through the windows meanwhile on the watch for some sign of the bursting of the hurricane.

He had not long to wait. Almost before he had found time to remove his hat and wipe the perspiration from his brow a shout came echoing up the staircase shaft from the bottom of the ship, announcing the fact that the trap-door was securely closed; and Sir Reginald instantly raised the ship from the ground, sending the engines gently ahead at the same moment, and putting the helm hard over so as to bring the _Flying Fish_ stem-on to the direction from which he expected the hurricane.

CHAPTER SIXTEEN.

A BATTLE ON LAKE TANGANYIKA.

The ship had risen about one hundred feet from the ground, and her engines had just completed a single revolution, when the black pall of murky cloud suddenly burst apart on the south-western horizon, revealing a broad patch of livid coppery-looking sky behind it; and at the same moment a low moaning sound became audible in the breathless air. A dull smoky grey veil of vapour seemed at the same time to overspread the more distant features of the landscape in that quarter, and through it the baronet and his three companions, who had now rejoined him, saw the trees and foliage of the most remote clumps of bush bowing themselves almost to the ground before some mighty invisible force. The moaning sound rapidly increased in power and volume, the cloud of vapour rushed down toward them with appalling speed; the long billowy gra.s.s was flattened down to the earth, as if under the pressure of a heavy roller; the successive clumps of bush were seen to yield one after the other to the resistless power of the hurricane, and the air in that direction grew dark with the leaves and branches which were torn from the trees.

"Raise the ship higher. Lift her above the power of the hurricane altogether if you have still time to do so," shouted the professor in Sir Reginald's ear, as the roar of the approaching tornado thundered in their ears with almost deafening intensity.

"No," shouted back the baronet; "I am going to try the experiment of seeing how she will bear the stroke of the gale. Hold on tight all of you!"

And as he spoke he sent the engines ahead at full speed, and drove the ship forward right in the teeth of the hurricane.

The next instant, with an appalling burst of sound, the gale was upon them. Contrary to their expectations, there was scarcely any perceptible shock, but the ship's speed was rapidly checked much as is the speed of an express train when the brakes are suddenly and powerfully applied, and in some six seconds, though the engines were still going ahead at their utmost speed, the progress of the _Flying Fish_ over the ground was as effectually checked as though she had been lying at anchor.

Meanwhile the air was one vast volume of awful sound, and thick with the clouds of dust, and tufts of gra.s.s, and leaves, and hurtling branches which were being whirled furiously along upon the wings of the tornado, so that the inmates of the pilot-house could neither hear each other speak nor see any object beyond a quarter of a mile away on either side.

This lasted for perhaps three minutes, when the wind suddenly lulled, and the ship at once began to forge rapidly ahead. The lull lasted perhaps half a minute, and then ensued a repet.i.tion of all that had gone before, excepting that perhaps the wind was not _quite_ so strong as at the first outburst. But it was of longer duration, the second instalment of the gale lasting fully half an hour, after which the wind gradually dropped to a gentle breeze, the sky cleared, the sun reappeared in all his wonted splendour, and the air resumed its usual transparency.

But what a sight was now presented to the view of the travellers; what a scene of devastation was that which lay outspread around them! The long gra.s.s was pressed so flat to the ground that it would scarcely have afforded cover to the smallest animal; stately trees were lying prostrate, either uprooted altogether, or their ma.s.sive trunks snapped short off, whilst others still retained their upright position indeed, but stood denuded of every branch. Other trees again, whilst less mutilated as to their branches, retained only a few straggling leaves here and there, and the same thing applied to those dense patches of creeper-like tangled growth known as "bush," the upper portions of which presented merely a bristling array of leafless twigs. And in some spots could be seen huge clumps of "bush" which had been torn bodily out of the ground and swept remorselessly along for perhaps miles of distance.

But the strangest sight of all was presented by the animals. From a height of one thousand feet, to which the _Flying Fish_ had by this time risen, a very wide extent of the plateau below could be surveyed, and on this in every direction could be seen the wild creatures of the forest, the jungle, and the plain, many of them suffering from injuries more or less severe, received during the progress of the tornado, and all of them exhibiting unmistakable and in some instances surprising evidences of demoralisation and terror. Deer and antelopes of various species lay crouched upon the ground palpably quivering with fear, or limped painfully about on three legs, the fourth being doubtless injured through the creature having been hurled violently to the ground, or struck by some falling branch. The lion and his mate could be seen here and there wandering harmlessly and aimlessly to and fro in the midst of hundreds of creatures which on ordinary occasions would afford them a welcome prey, but which were now too completely overcome with terror to notice their presence. In one place a fine elephant lay prostrate, his ma.s.sive spine apparently broken by the fall of an enormous tree, the trunk of which had pinned him to the ground; and in another, an immense a.s.semblage of animals of the most mixed and antagonistic species were seen huddled promiscuously together under the lee of an immense belt of bush, where they seemed to have found a shelter from which they were evidently still afraid to venture.

At length, having seen enough to afford them a tolerably clear idea of the destruction wrought by the storm, the professor suggested the retracing of their steps with the object of again finding, if possible, the troop of unicorns. The ship was accordingly put about, and in a short time the spot was reached on which still lay the carca.s.ses of the leopard and the female unicorn. Here she was again brought temporarily to the ground in order that the party might secure the two skins, which was done; but the hide of the unicorn was so dreadfully lacerated by the claws of the leopard that the professor was plunged into the lowest depths of chagrin and despondency. The pursuit of the lost animals was now once more taken up; the ship rising to a height of five thousand feet into the air and then going ahead dead slow in the direction taken by the unicorns, the four gentlemen, armed with their most powerful telescopes, posting themselves in advantageous positions on deck and minutely examining every yard of the ground over which they pa.s.sed.

This method of proceeding was continued until nightfall without result; and it then became evident that the animals of which they were in pursuit had somehow eluded them.

"Well," said the professor, endeavouring to put a good face upon his disappointment, as, the ship having been carefully brought to earth and securely moored for the night, the party left the pilot-house and went below to take their evening bath previous to dinner, "it is disappointing, but it cannot be helped. Perhaps we shall be fortunate enough to encounter them or others to-morrow as we wend our way southward. And, _a propos_ of our next destination, I have a suggestion which I should like to make, and which I will lay before you when we meet at the dinner-table."

Accordingly, when they had fairly settled down to the meal that evening, Sir Reginald called upon the scientist for his suggestion or proposal.

"I must preface it," said von Schalckenberg, "by informing you that I have again been diving into my lamented friend's note-book, which I may say _en pa.s.sant_ is the most remarkable volume I have ever come across.

And in it I find, under the heading of 'Africa,' a most clever and scholarly disquisition on 'the site of ancient Ophir,' the place from which it is recorded that David obtained gold for the building of Solomon's temple. I need not inflict upon you the various arguments and authorities which are cited in the endeavour to ident.i.ty the position of this most interesting spot; suffice it to say, that I am morally convinced I can lay my finger upon it on the map. The princ.i.p.al, indeed I may say the _only_ reasons why the region has never yet been explored are, first, its extreme difficulty of access except by sea; and secondly, the fact that all recorded attempts to penetrate it have been thwarted by the inhabitants, who are a most jealous, warlike, and savage race of people. _We_, however, are fortunately possessed of exceptional, or I should rather say unique, means of approach to this unknown country; and my suggestion is that we should--"

"Do it," interrupted the baronet. "Most certainly we _will_, my dear sir, and I am exceedingly obliged to you for the proposal. The adventure will doubtless possess a piquant flavouring of danger about it, but I presume that will scarcely be regarded by any of us as a drawback?" glancing across the table to the colonel and Mildmay.

"Scarcely," echoed Lethbridge lazily, as he held his gla.s.s of wine up critically to the light.

"Did you say 'danger?'" laughed Mildmay. "This craft of yours is so confoundedly safe, Sir Reginald, that upon my word I have almost forgotten what danger is; so if you really think you can find a place where we may once more come within hail of it, pray take us there without loss of time. For my part, I am becoming positively effeminate, and unless I can speedily have a chance of getting my head broken I shall be utterly ruined for 'the service' when I go back to it."

"So be it," said the baronet. "Ancient Ophir is our next destination; and we will start to-morrow morning. You, professor, I know will not shrink from danger when the solving of so interesting a question is concerned."

"Ah, ah! try me," laughed the professor joyously--"try me, my friend, and you shall see."

Accordingly, on the following morning after breakfast a general adjournment was made to the pilot-house, where, with map and chart spread out before them, and the professor's treasured volume beside them for reference, the probable site of ancient Ophir was at length definitely located; when the course and distance were ascertained, and a start made.

Being anxious to see as much as possible of the country during their pa.s.sage over it, a low rate of speed--averaging about twenty miles per hour--was maintained; the day's journey beginning at six o'clock in the morning, and terminating at the same hour in the evening, when a halt was called and the ship brought to earth for the night.

On the fourth day of this part of their journey, shortly after effecting their morning's start, they came within sight of an immense lake; and a slight deviation from their prescribed course was made in order that a thorough examination of it might be effected. A long range of hills, which had been sighted on the previous day, lay on their left hand; and, on clearing the southern spurs of these, they found that another large body of water lay beyond or to the eastward of them; a river connecting the two lakes, afterwards identified by them as lakes Albert Nyanza and Tanganyika. Rising in the air to a height of about ten thousand feet, they slowly traversed the latter from its northern extremity, reaching its widest part--which they estimated to be about sixty miles across--at mid-day.

And here a most exciting scene presented itself. An hour previously a dark ma.s.s had been sighted near the western sh.o.r.e of the lake, which ma.s.s had at first been taken for an island; but, on a nearer approach, the supposed island had resolved itself into an immense fleet of canoes, in number about three hundred, manned by from four to twenty men in each, rapidly making its way toward the western sh.o.r.e. So large a concourse of craft, coupled with the fact that the crews were elaborately "got up" with paint, feathers, and skins, and were well provided with bows and arrows, spears, shields, and clubs--to say nothing of a few very antiquated-looking muskets which the travellers'

gla.s.ses revealed here and there--seemed to point to the conclusion that a hostile expedition was afoot, or, rather, afloat; and the explorers resolved upon a temporary pause in order to watch the course of events.

The natives were so intent upon their paddling that--facing forward as they all were, with the _Flying Fish_ somewhat in their rear and nearly a mile above them--not one of them seemed to have detected the near vicinity of the aerial ship; and the fleet diligently pursued its course landward, the short broad-bladed paddles moving to the time of a deep, sonorous, but somewhat monotonous song, which, issuing as it did from the throats of probably quite two thousand warriors, was distinctly audible on board the _Flying Fish_, and really had quite an impressive effect.

The flotilla had reached within about four miles of the sh.o.r.e, and of a tolerably extensive native settlement built thereon on both sides of a river which at that point emptied itself into the lake, when a sudden confused beating of drums and blowing of horns seemed to indicate that the menaced tribe had at last become awakened to the unpleasant fact that an invasion of their territory was imminent. The summons was responded to with very commendable celerity, the men swarming out of the settlement like ants out of an ant-heap; and in less than ten minutes nearly a hundred canoes were launched and manned, and advancing boldly to meet the enemy, whilst the laggards pushed off by twos and threes as soon afterwards as they could get down to the beach, all making the most strenuous efforts to join the main body.

To the observers on board the _Flying Fish_ it seemed that the attacked party had made a grave mistake in thus taking to their canoes and advancing in them to meet the enemy; the colonel's impression being that they would have done better if they had awaited their foes on the beach and hara.s.sed them during their attempt to effect a landing. But it soon became evident that the threatened tribe knew perfectly well what they were about, their canoes being larger and steadier than those of their opponents, and their method of handling them greatly superior.

The opposing forces encountered each other at a distance of about two miles from the western sh.o.r.e of the lake, when a simultaneous discharge of arrows was poured in by both sides, after which the two fleets closed, and a most determined and sanguinary battle commenced. The invaders outnumbered their opponents nearly in the proportion of two to one; yet the latter not only gallantly held their own, but actually appeared now and then to gain some slight temporary advantage. Spears were thrown and arrows were shot by hundreds; the heavily-k.n.o.bbed war- clubs were wielded with untiring activity and terrible effect; and, occasionally, a flash and a faint puff of smoke followed by a report told that one of the ancient muskets had been brought into play. The shouting of commands, the cries of anguish or defiance, the shrieks of the wounded, and the yells of triumph united in the creation of a most deafening din; and that it was not noise only, but work as well, was speedily manifested by the numerous bodies, splashing and struggling in the agonies of death, or floating quiescent on the surface of the lake.

"How stubbornly the rascals fight!" remarked Lethbridge at last, when the battle had been hotly raging for fully three-quarters of an hour without yielding to either side any decided advantage. "I wonder what the quarrel is all about?"

"It is difficult to say," answered the professor, who seemed to consider the question as addressed to himself; "it may be a simple case of tribal animosity; it may be an attack of retaliation; or it may be a slave- hunting expedition. It is pretty sure to be one or the other of those three, but it is impossible to say which."

"Well," remarked Mildmay, "whatever the cause of the fight, my sympathies are all with the weaker side. Cannot we help the poor wretches a little? A shot or two from our rifles--"

"Would ensure to either party a victory," interrupted the baronet.

"Yes; that is quite true. But how can we tell which party--if either-- is fighting in the cause of right and justice? We cannot take the part of either the aggressors or the defenders without a certain lurking doubt that in so doing we may perhaps be unwittingly giving aid and encouragement to the evil-doer. My sympathies are, like yours, on the side of the defenders; but I am afraid we must let them fight it out unaided."

And fight it out they did in the most gallant manner, the invaded baffling all attempts on the part of the invaders to get even a small portion of their force between them and the sh.o.r.e; and finally, by what looked like a last supreme and desperate effort, putting the foe to flight, and pursuing him triumphantly and persistently in his retreat, hara.s.sing his rear, cutting off and capturing stragglers, and in every possible way worrying and annoying him so thoroughly that, to those on board the _Flying Fish_, it looked unlikely in the extreme that the attack, whether provoked or not, would ever be repeated.

The combatants had evidently been far too busy to notice the extraordinary apparition floating in the sky above them; but just as the battle was about to commence a crowd of women and children, with a few decrepit old men, had a.s.sembled on the beach, seemingly to watch the conflict; and on bringing the telescopes to bear on these it soon became apparent, by their gestures and cries of amazement, that they had seen the ship.

"Yes," said the professor, peering through his telescope, "they see us undoubtedly, but they can detect neither form nor details. The sun is immediately behind them, you will observe; consequently, as it is shining full upon our burnished hull, those people, in the position they now occupy, will be able to see nothing but a shapeless blaze of dazzling effulgence, which they will doubtless take as an outward manifestation of their particular deity's favour, and an indication that he is present to crown their cause with victory."

And indeed there was plenty of evidence to support this singular opinion, for the people, though evidently astonished beyond measure, manifested delight rather than fear at what they saw, stretching out their hands, palms upward, by way of greeting and salute, whilst many were seen to hurry away to the village and back, bringing with them offerings of fruit, goats, and fowls, which they ranged in a line ("in order to make the most of them," as Mildmay suggested) along the margin of the lake. The proffered offering was, however, unaccepted, and, the battle being over, the _Flying Fish_ resumed her course along the centre line of the lake, reaching its southern extremity in time to select a halting-place before sunset.

The fourth day following found them within easy distance of their destination; and the disappointment of the travellers, arising from the fact that no more unicorns had been seen, was to a very great extent swallowed up in curiosity as to what lay before them. Shortly after effecting their morning's start the fertile region over which they had hitherto been travelling came abruptly to an end, and they found themselves pa.s.sing over an arid sandy desert, utterly dest.i.tute of even the feeblest suggestion of vegetation, without a trace of water or even of moisture, and of course with no sign of a living creature anywhere upon it. So uninteresting a region offered no temptation for loitering or dalliance, and the speed of the ship was accordingly increased to about sixty miles an hour over the ground, the pace being maintained until two o'clock in the afternoon, when a low range of rocky precipitous hills was reached, beyond which fertility and life once more resumed their sway. The travellers computed the stretch of desert over which they had pa.s.sed as being fully three hundred miles in extent, and they could therefore fully understand the difficulty--not to say impossibility--of approaching Ophir, at all events from a north-westerly direction. Speed was now once more reduced, the ship gently gliding through the hot afternoon air at the rate of about eighteen knots, over a somewhat rugged, well-wooded country, watered by numerous streams, with native villages dotted here and there along the banks, in the midst of well-cultivated maize and tobacco fields, with an occasional patch of sugar-cane. Large herds of cattle were also frequently pa.s.sed, and it soon became evident that to the natives in charge of these, and indeed to the inhabitants generally, the apparition of the aerial ship was productive of a vast amount of curiosity, excitement, and wonder. These natives appeared to possess the same power or gift attributed to the Montenegrins, namely, that of projecting the voice for incredible distances through the air; and it was speedily apparent that the arrival of the monster aerial visitant to the country was being orally telegraphed forward in the direction of her course. Mounted men were seen dashing madly along until they reached some eminence favourably situated for the exercise of their powers, when, dismounting, the messenger would raise his hands to his lips, and, in a peculiar high- pitched tone of voice which seemed to have the power of penetrating the air for an immense distance, send his message echoing forward over hill and dale, to be instantly caught up and repeated by another. So smartly was this novel system of telegraphy performed, that the message actually outsped the ship, and the travellers found the inhabitants of every village along their route awaiting _en ma.s.se_ their appearance, which was instantly greeted with loud shouts of astonishment. At one village or settlement, which, from its size, appeared to be of more than ordinary importance, they found, in addition to the general inhabitants, a squadron of about fifty mounted warriors awaiting them, fully armed with bow, spear, and shield, and upon the appearance of the _Flying Fish_ these troops most pluckily ranged themselves directly across her course and prepared to treat her to a shower of arrows.

"Now is our time to create a wholesome impression of our invincibility upon these fellows," remarked the baronet, and hurrying to the pilot- house he caused the ship to sink well within range of the projected salute.

In an instant every bow was drawn to its utmost tension, a second or two sufficed the warriors to steady their aim, and then, with a simultaneous _tw.a.n.g_ of bowstrings, the fifty arrows sped through the air, and, rattling harmlessly against the ship's gleaming hull, glanced off and fell to the earth again. The baronet smartly raised the fore end of the tiller, and, obedient to her helm, the _Flying Fish_ made a sudden swoop earthward in the direction of the audacious cavalry, who, already disconcerted at the utter failure of their attack, at once wheeled short about, and, with piercing yells of terror, took headlong flight, jostling and overthrowing each other without the least compunction in their frantic eagerness to escape.
