The Log of the Flying Fish Part 5

Can you give us a little light on the subject, professor?"

By way of reply the professor pressed a k.n.o.b, and the lamp itself flashed its dazzling light upon the scene, when it became apparent that the s.h.i.+p had gradually risen from the ground, bringing the top of her lamp just above the level of the last tie-rod of the roof.

"Can you drop her a little? Six inches will do it," said the baronet.

The professor opened the air-valve and the s.h.i.+p at once began to settle down.

"So! That will do; all clear. You may go astern again now as fast as you please," said the baronet.

Once more the great propeller began to revolve, and presently the baronet, from his position under the foremost end of the pilot-house, remarked:

"Now she is all clear, professor; the whole of the pilothouse is outside the shed. A bold dash astern now and we shall be clear fore and aft in another moment."

The professor extinguished the electric lamp; gave the wheel connected with the vapour-valve another turn; the engines increased their speed; and the great s.h.i.+p at once shot rapidly out over the stream and clear of everything. Then the professor stopped the engines, turned a thin stream of vapour into the air chambers, and the huge fabric began to slowly rise perpendicularly in the air. Herr von Schalckenberg waited until he saw that they were fairly above the level of the roofs on both sides of the river; then he left the pilot-house and, joining the baronet on the deck outside, said, in a voice of undisguised exultation:

"Well, Sir Reginald, what think you _now_ of the _Flying Fish_?"

"I think her, professor, a wonderful creation of a still more wonderful man. I see that we are steadily rising in the air, as you a.s.sured us would be the case, but I cannot yet fully realise the fact; I feel like a man in a dream; you must give me time to become familiar with this new marvel--this new triumph of science. But there can no longer be any doubt as to the success of your labours; and I accordingly offer you my most hearty thanks and congratulations."

The colonel and the lieutenant also hastened to offer theirs, and then the whole party sauntered to the side, and, leaning upon the guard-rail which took the place of bulwarks, stood gazing upon the scene below.

Not that there was very much to see; the sky was obscured by a thin almost motionless canopy of cloud, and the moon, in her last quarter, had not yet risen; the darkness was therefore profound. At the same time it was novel and interesting to watch how, as the huge s.h.i.+p rose steadily higher in the air, the long lines of lighted gas-lamps in street after street became visible, until gradually the whole of the great city lay spread out below them like a map, with the thoroughfares indicated by faint twinkling lines of fire. And, as they continued to rise, the various disjointed sounds which, even at that early hour, pervaded the city, began to reach their ears: the rumbling of a wagon or the rattle of a cab over the stone-paved streets, the barking of a dog, the crow of some unnaturally wakeful rooster, the clank of shunting trucks at one or another of the many goods stations dotted here and there all over the metropolis, the distant whistle and rattle of a train speeding along in the open country beyond; all floated up to them with almost startling distinctness at first, then fainter and fainter, until at length they died completely away as the _Flying Fish_ gradually attained a higher alt.i.tude. Then they entered the bank of cloud which overspread the city, and the air, which had hitherto been warm, became suddenly chill and damp.

"Now, my friends," said the professor, "there will be little or nothing more to see until we again descend; I therefore propose that we return to the pilot-house, shut ourselves in, and at once test the soaring powers of the s.h.i.+p by rising to the highest attainable alt.i.tude."

"Agreed!" said the baronet. "But why shut ourselves in?"

"Because," answered the professor, "it will not only grow rapidly colder as we rise, but, if we remain outside, we shall also find it increasingly difficult to breathe as we reach the more rarefied air; whereas, by remaining inside, we shall be sheltered from the cold and shall be able to breathe the denser air which we shall take up with us."

They accordingly entered the pilot-house, shutting the door after them, and closing all the windows; then the professor turned a full jet of vapour into the air-chambers for a moment, producing a perfect vacuum therein, and the s.h.i.+p at once began to mount into the ether with greatly accelerated speed, as they could easily see by watching the barometer, the bulb of which, completely protected, was situate outside the walls of the pilot-house.

It was no very easy matter for cold to penetrate through the thin yet obdurate walls of the pilot-house; but by the time that the barometer had fallen to fifteen inches the voyagers experienced a distinct sensation of chilliness, whilst the windows of the pilot-house were thickly coated with a delicate frost tracery. Still the barometer continued to fall steadily, though not so rapidly as at first, indicating that the s.h.i.+p was still soaring upward; and with every inch fall of the mercury the professor became an increasingly interesting study of mingled delight and anxiety. At length the mercury, still falling, registered a height of eleven inches only, and the professor gave vent to a great sigh of relief. And when it further dropped to ten inches he could no longer contain himself.

"Gentlemen," he exclaimed, "rejoice with me. The conquest of the mountains is ours. We are now as nearly as possible on a level with the topmost peak of Everest, the most lofty projection on the earth's surface; and in due time I hope we shall have the unique felicity of planting our feet on that as yet untrodden spot, and of leaving a record to that effect behind us."

At length the mercury fell to a little below eight inches, and there it stopped; the limit of the _Flying Fish's_ buoyancy was reached.

The professor stood intently regarding the barometer tube for some time; then he turned and said to his companions:

"Gentlemen, behold the indisputably lowest reading of the barometer which man has ever witnessed, and which indicates that we are at this moment farther from our mother earth than mortal has ever journeyed before. Humboldt and Bonpland ascended Chimborazo to a height of eighteen thousand five hundred and seventy-six feet. Gay-Lussac rose in his balloon to the much higher elevation of twenty-three thousand feet, only to be eclipsed by your own countryman, Green, who soared to the astounding height of twenty-seven thousand six hundred feet. But it was left for _us_, my friends, to achieve the crowning feat of aeronautical science, by attaining to the extraordinary alt.i.tude of thirty-four thousand six hundred feet, or more than six and a half miles of perpendicular elevation above the sea-level. _Now_, Sir Reginald, what think you of your latest acquisition, the _Flying Fish_?"

"I think her by far the most wonderful creation of which I have ever heard or read, and," (with a bow to the professor) "every way worthy of the truly remarkable man to whom she owes her existence. If her power to penetrate the hitherto unexplored depths of the ocean is at all commensurate with her ability to reach the higher regions of the air, I foresee that our voyage is likely to be fruitful in startling incident and in the discovery of many hitherto unsuspected secrets of nature.

Now, what do you propose that we shall next do, professor?"

"I propose," said von Schalckenberg, "that, having tested the _Flying Fish's_ capabilities of merely rising into the air, we should now ascertain what she can do in the way of _navigating_ the atmosphere; after which we will try her powers as a submarine s.h.i.+p. The lowest depression in the English Channel is to be found in a submarine valley called the 'Hurd Deep;' it is situate about six miles north of the 'Casquets,' and lies ninety-four fathoms (or five hundred and sixty-four feet) below the surface of the water. I propose (subject to your approval) to make for this spot and there sink to the bottom, taking advantage of our presence there to make a first trial of our diving armour. Does this meet with your approval?"

The baronet and his companions thought it a very capital idea, and the professor took immediate steps for carrying it out. Opening a case he produced therefrom a chart of the English Channel, and, directing his companions' attention to the spot which he proposed to visit, requested Lieutenant Mildmay to lay off the course and measure the distance in a straight line. The latter was found to be about one hundred and fifty miles.

"Which distance," remarked the professor, "I expect we shall accomplish, in the present calm state of the atmosphere, in about an hour and a quarter. This high rate of speed will necessitate our remaining in the pilothouse; but it will, perhaps, be worth while to put up with that temporary inconvenience on the present occasion, since we have so exceptionally favourable an opportunity of testing the actual speed of the s.h.i.+p through the air. If, however, you prefer to be on deck in the open air, we can of course moderate our speed sufficiently to render such a mode of travelling pleasant."

It was unanimously decided, however, to remain inside and give the speed of the s.h.i.+p a fair trial. The professor accordingly turned the vapour into the engines, slowly at first, but in gradually increasing volume, until they were revolving at full speed, and the s.h.i.+p's head was pointed in the proper direction, the automatic steering gear being at the same time thrown into action to test its capabilities. This done the professor opened the main air-valve, gradually admitting a certain quant.i.ty of air into the s.h.i.+p's interior, and she at once began to drop once more earthward.

"We will descend to within about a thousand feet of the sea level," said the professor. "This will restore us to a more genial temperature, will give the propeller a denser atmosphere in which to work, and will also enable us to see somewhat of the country over which we are flying; whilst our elevation will be ample to take us clear of everything.

Leith Hill, nine hundred and sixty-seven feet in height, is the greatest elevation at all near our path; but we shall pa.s.s some three miles or so to the westward of it, if the air remains calm; and Saint Catherine's Point, over which we shall pa.s.s, is only seven hundred and seventy-five feet high. So that we have nothing to fear."

In a few minutes the _Flying Fish_ had dropped to within the proposed distance of the earth; and, on clearing the windows of the acc.u.mulated frost, it was discovered that the moon (then in her third quarter) had risen and was suffusing the earth with her feeble ghostly light, which, slight as it was, enabled the voyagers to perceive that they were skimming through the air at a tremendous speed. The engines, though working at their full power, were perfectly noiseless; and the propeller, though revolving at a rate of fully one thousand revolutions per minute, caused not the slightest perceptible vibration in the hull of the s.h.i.+p. A loud humming sound, however, proceeded from it, audible even above the rush of the air against the sides of the pilot-house.

Leith Hill was soon pa.s.sed, the waters of the Channel--distinguished in the faint light only by a thin tremulous line of glimmering silver under the crescent moon--were sighted, and, almost before they had time to realise the fact, they had skimmed over the anchorage at Spithead, across the Isle of Wight, and were floating above the waters of the Channel. By this time the eastern sky had begun to pale perceptibly before the coming dawn; the lights of Saint Catherine behind them and the Casquets ahead gleamed with steadily diminis.h.i.+ng power in the gathering daylight; the half-dozen or so of s.h.i.+ps and steamers in sight, one after the other extinguished their signal lamps; and, just as they reached their destination and settled lightly as a snow-flake upon the gla.s.sy surface of the water, up rose the glorious sun, flas.h.i.+ng his brilliant beams over land and sea, and awakening all nature into light and life once more.

As the _Flying Fish_ alighted on the surface of the water, the professor pulled out his watch and remarked, with evident satisfaction:

"One hundred and fifty miles in just one hour and a quarter! That is good travelling, and proves the speed of our s.h.i.+p to be exactly what I estimated it would be. We will now set the force-pump to work; and I hope, that by the time we are ready to descend, that brilliant sun will have enshrouded our movements in a concealing mist. We are surrounded by fis.h.i.+ng-boats, as you see, and I have no doubt that we have also been observed by the light-keepers on the Casquets. It will never do to disappear before so many curious eyes; they would be filled with horror at the supposed catastrophe. In the meantime we may as well go out on deck to enjoy the fresh morning air. As for me, I propose to indulge in the luxury of a swim."

The main engines had, in the meantime, been stopped, and the force-pump put slowly in motion, so that the submersion of the hull might be sufficiently gradual to escape notice.

Five minutes later the professor and his three companions were gambolling round the s.h.i.+p like so many porpoises--or dolphins, if they would prefer the latter metaphor--enjoying to the full the invigorating luxury of their bath in the cool, pure sea-water.

By the time that they were on board again and dressed, the intelligent George had arranged for them on deck a nice little light breakfast of chocolate, biscuits, and fruit, for which their swim had given them an unbounded relish. The meal was partaken of at leisure, and followed by a cigar, over which they dawdled so long that the _Flying Fish_ was submerged to the deck before the last stump had been reluctantly thrown away. The mist which the professor had prognosticated having, meanwhile, gathered sufficiently to cloak their movements, a cast of the lead was taken and the s.h.i.+p was found to be in ninety fathoms of water.

The professor, for reasons of his own, deemed this sufficiently near the deepest point to justify an immediate descent. They accordingly entered the pilot-house forthwith, closing the door securely after them--the air-pump was stopped, the sea-c.o.c.k communicating with the water-chambers was opened, and the _Flying Fish_, with an easy imperceptible motion, sank gently beneath the placid waters, to rest, a minute or two later, on a bed of gravel at the bottom of the Channel.

"Now," said the professor, looking at his watch when the s.h.i.+p had fairly settled into her strange berth, and had been securely anch.o.r.ed there, "it is just eight o'clock. We are all somewhat fatigued, and our bath and breakfast have prepared us nicely to enjoy a few hours' repose. I therefore propose, gentlemen, that we retire to our sleeping apartments until two o'clock p.m. George shall call us at that hour and have a bit of luncheon ready for us, after which we shall have ample time to test our diving apparatus before dinner."

This proposal met with a very cordial reception, and was duly carried out, with the result that, half an hour later, the four adventurous voyagers were sleeping as calmly in their novel resting-place as though they had been accustomed from their earliest infancy to take their repose at the bottom of the sea.

CHAPTER FIVE.

A SUBMARINE EXCURSION.

At the appointed hour the imperturbable George, who never could be betrayed into the slightest exhibition of astonishment at finding himself in any extraordinary situation which he might happen to be sharing with his somewhat eccentric master, duly aroused the four sleepers, and when they were ready, laid luncheon before them with the same indomitable _sangfroid_ which he would have exhibited had the transaction been conducted on _terra firma_.

The meal over, the professor led the way below to the diving chamber, where the adventurous four carefully donned their diving dresses, inclusive of the armour which Sir Reginald felt so strongly disposed to ridicule. As this was the first occasion of inducting themselves into their novel costume, they were rather a long time about it; but when once they were fairly encased, they were fain to admit that, strange as might be their appearance, they felt exceedingly comfortable. The professor was the last to a.s.sume the dress, having busied himself in the first instance in a.s.sisting the others; but at length all was ready, and they filed into the exit chamber, carefully closing the door behind them. This chamber was illuminated by an electric lamp, the light of which clearly revealed the whereabouts of the sea-c.o.c.k, and of the fastenings to the trap-door, all of which the professor pointed out to his companions, at the same time explaining the method of working them.

The sea-c.o.c.k was then opened, and the chamber began to slowly fill with water.

"Now," explained the professor, "please listen to me. If now, or at any future time, either of you should experience the slightest sensation of discomfort as the water rises round you, all you have to do is simply to open this air-c.o.c.k, which communicates with the air-chambers, and the condensed air will at once rush in and expel the water again; then close the sea and air c.o.c.ks; open this relief valve, which will allow the condensed air to disperse itself in the habitable portions of the hull, and you can at once open the door of communication to the diving chamber, and disenc.u.mber yourself of your dress, remembering always to close the door behind you. Now, do either of you feel at all uncomfortable?"

The exit chamber was by this time full of water, and its occupants were, therefore, completely submerged, and subject to the same pressure of water as they would be outside, but the armour proved fully equal to its work in every respect, and its wearers were able to move with just as much freedom and ease as if they had been on dry land. They accordingly replied to the professor's inquiry with a brisk negative.

"And can you hear distinctly what I say?" continued the professor.

They replied that they could hear every word perfectly, only realising when the question was asked that they were completely sheathed in metal from head to foot, and that, consequently, the fact of their being able to hear at all was somewhat singular.

"That is all right," exclaimed the professor. "I thought it would be convenient if we could communicate freely with each other under water, so I introduced a couple of small microphones into each helmet, hoping they would answer the purpose. Mine are simply perfect, but I was anxious to know if yours were also. Now, if you are quite ready I will open the door."

The next moment the trap-door fell open, and a great black aperture yawned before them.

"Light both your lamps," exclaimed the professor, "and pick your footsteps. Remember, you are about to tread on strange ground."

The professor led the way, his armour-clad figure looming up black and gigantic against the two overlapping discs of illuminated water before him, and the other three followed closely in his footsteps. On emerging from the trap-door they turned sharp to the left, and made their way toward the bow along the tunnel-like pa.s.sage between the s.h.i.+p's bottom and the starboard bilge keel. This was soon traversed, and they then found themselves on a tolerably firm, level, gravelly bottom. Emerging from underneath the s.h.i.+p's bottom, they now extinguished their lamps for a moment by way of experiment, and found that so clear was the water that even at the great depth of ninety fathoms it was not absolutely dark, a sombre greenish blue twilight prevailing in which the hull of the s.h.i.+p towered above them vast and shadowy, yet with tolerable distinctness. This twilight, however, was strongly illuminated at both ends of the s.h.i.+p by the powerful electric lamps at the bow and stern, all of which the professor had taken the precaution to light before descending to the diving chamber.
