The cave was enshrouded in almost total darkness when they entered it, but this was quickly dispelled, to Nigel's no little surprise, by the rays of a magnificent oil lamp, which Moses lighted and placed on the table in the larger cave. A smaller one of the same kind already illuminated the kitchen.
Not much conversation was indulged in during the progress of the supper that was soon spread upon the rude table. The three men, being uncommonly hungry and powerfully robust, found in food a sufficient occupation for their mouths for some time.
After supper they became a little, but not much, more sociable, for, although Nigel's active mind would gladly have found vent in conversation, he experienced some difficulty in making headway against the discouragement of Van der Kemp's very quiet disposition, and the cavernous yawns with which Moses displayed at once his desire for slumber and his magnificent dental arrangements.
"We always retire early to rest after a day of this sort," said the hermit at last, turning to his guest. "Do you feel disposed for bed?"
"Indeed I do," said Nigel, with a half-suppressed yawn, that was irresistibly dragged out of him by the sight of another earthquake on the negro's face.
"Come, then, I will show you your berth; we have no bedrooms here," said the hermit, with a sort of deprecatory smile, as he led the way to the darker end of the cavern, where he pointed to a little recess in which there was a pile of something that smelt fresh and looked like heather, spread on which there was a single blanket.
"Sailors are said to be indifferent to sheets. You won't miss them, I daresay?"
"Not in the least," returned Nigel, with a laugh. "Good-night," he added, shaking hands with his host and suppressing another yawn, for Moses' face, even in the extreme distance, was irresistibly infectious!
Our hero was indifferent not only to sheets, but also, in certain circumstances, to the usual habiliments of night. Indeed, while travelling in out-of-the-way regions he held it to be a duty to undress but partially before turning in, so that he might be ready for emergencies.
On lying down he found his mattress, whatever it was, to be a springy, luxurious bed, and was about to resign himself to slumber when he observed that, from the position in which he lay, he could see the cavern in all its extent. Opening his half-closed eyes, therefore, he watched the proceedings of his host, and in doing so, as well as in speculating on his strange character and surroundings, he became somewhat wakeful.
He saw that Van der Kemp, returning to the other end of the cave, sat down beside the lamp, the blaze of which fell full on his fine calm countenance. A motion of his head brought Moses to him, who sat down beside him and entered into earnest conversation, to judge from his gestures, for nothing could be heard where Nigel lay save the monotonous murmur of their voices. The hermit did not move. Except for an occasional inclination of the head he appeared to be a grand classic statue, but it was otherwise with the negro. His position in front of the lamp caused him to look if possible even blacker than ever, and the blackness was so uniform that his entire profile became strongly pronounced, thus rendering every motion distinct, and the varied pouting of his huge lips remarkably obvious. The extended left hand, too, with the frequent thrusting of the index finger of the other into the palm, was suggestive of argument, and of much reasoning effort—if not power.
After about half-an-hour of conversation, Moses arose, shook his master by the hand, appeared to say "Good-night" very obviously, yawned, and retired to the kitchen, whence, in five minutes or so, there issued sounds which betokened felicitous repose.
Meanwhile his master sat motionless for some time, gazing at the floor as if in meditation. Then he rose, went to his book-case and took down a large thick volume, which he proceeded to read.
Nigel had by that time dropped into a drowsy condition, yet his interest in the doings of his strange entertainer was so great that he struggled hard to keep awake, and partially succeeded.
"I wonder," he muttered, in sleepy tones, "if that's a f—fam—'ly Bible he's reading—or—or—a vol'm o' the En—Encyclopida Brit—"
He dropped off at this point, but, feeling that he had given way to some sort of weakness, he struggled back again into wakefulness, and saw that the hermit was bending over the large book with his massive brow resting on the palms of both hands, and his fingers thrust into his iron-grey hair. It was evident, however, that he was not reading the book at that moment, for on its pages was lying what seemed to be a miniature or photograph case, at which he gazed intently. Nigel roused himself to consider this, and in doing so again dropped off—not yet soundly, however, for curiosity induced one more violent struggle, and he became aware of the fact that the hermit was on his knees with his face buried in his hands.
The youth's thoughts must have become inextricably confused at this point, yet their general drift was indicated by the muttered words: "I—I'm glad o' that—a good sign—an'—an' it's not th' Encyclop–." Here Morpheus finally conquered, and he sank into dreamless repose.
How long this condition lasted he could not tell, but he was awakened violently by sensations and feelings of dread, which were entirely new to him. The bed on which he rested seemed to heave under him, and his ears were filled by sharp rattling sounds, something like—yet very different from—the continuous roll of musketry.
Starting up, he sprang into the large cavern where he found Van der Kemp quietly tightening his belt and Moses hastily pulling on his boots.
"Sometin's bu'sted an' no mistake!" exclaimed the latter.
"An eruption from one of the cones," said the hermit. "I have been for a long time expecting it. Come with us."
He went swiftly up the staircase and passages which led to the observatory as he spoke.
The scene that met their eyes on reaching the ledge or plateau was sublime in the extreme, as well as terrific.
"As I thought," said Van der Kemp, in a low tone. "It is Perboewatan that has broken out."
"The cone from which I observed smoke rising?" asked Nigel.
"The same. The one over the very centre of the old crater, showing that we were wrong in supposing it to be extinct: it was only slumbering. It is in what vulcanologists term moderate eruption now, and, perhaps, may prove a safety-valve which will prevent a more violent explosion."
That the cone of Perboewatan was indeed in a state of considerable activity, worthy of a stronger term than "moderate," was very obvious. Although at a distance, as we have said, of four miles, the glare of its fires on the three figures perched near the top of Rakata was very intense, while explosion after explosion sent molten lava and red-hot rocks, pumice, and dust, high into the thickening air—clouds of smoke and steam being vomited forth at the same time. The wind, of which there was very little, blew it all away from the position occupied by the three observers.
"What if the wind were to change and blow it all this way?" asked Nigel, with very pardonable feelings of discomfort.
"We could return to the cavern," said the hermit.
"But what if Rakata itself should become active?"
It was evident from the very solemn expression on the negro's face that he awaited the reply to Nigel's question with some anxiety.
"Rakata," answered the hermit thoughtfully, "although the highest cone, is the one most distant from the great centre of activity. It is therefore not likely that the volcanic energy will seek a vent here while there are other cones between us and Perboewatan. But we shall soon see whether the one vent is likely to suffice. There is undoubtedly no diminution in the explosions at present."
There certainly was not, for the voice of the speaker was almost drowned by the horrible din caused, apparently, by the hurtling of innumerable fragments of rock and stones in the air, while a succession of fiery flashes, each followed by a loud explosion, lit up the dome-shaped mass of vapour that was mounting upwards and spreading over the sky. Vivid flashes of lightning were also seen playing around the vapour-column. At the same time, there began a fall of fine white dust, resembling snow, which soon covered the foliage and the ground of all the lower part of the island. The sea around was also ere long covered with masses of pumice, which, being very light, floated away into the Indian ocean, and these were afterwards encountered in large quantities by various vessels passing through Sunda Straits.
The Scientific Committee, which ultimately wrote on the details of this eruption in Krakatoa, mention this first outburst as being a phase of moderate activity, similar to that which is said to have been exhibited for some months during the years 1680 and 1681, and they added that "the outburst was one of considerable violence, especially at its commencement," that falls of dust were noticed at the distance of three hundred miles, and that "the commander of the German war-vessel Elizabeth estimated the height of the dust-column issuing from the volcano at 11 kilometres (36,000 feet or about 7 miles)."2
To our hero, however, and to Moses, the outburst seemed anything but "moderate," and that night as they two sat together in the cave after supper, listening with awe-struck faces to the cannonading and wild musketry going on as it seemed under their very feet, the negro solemnly imparted to Nigel in a low whisper that he thought "de end ob de wurld hab come at last!"
Returning at that moment from his observatory, to which he had ascended for a few minutes to view the scene through one of his glasses, Van der Kemp relieved their anxieties somewhat by remarking, in his quiet manner, that there was a distinct diminution in the violence of the explosions, and that, from his knowledge and experience of other volcanoes in Java, Sumatra, and elsewhere, he thought it probable they had seen the worst of it at that time, and that none of the other cones would be likely to break out.
"I'm glad to hear you say so," observed Nigel, "for although the sight is extremely magnificent and very interesting, both from a scientific and artistic point of view, I cannot help thinking that we should be safer away from this island at present—at least while the volcano is active."
The hermit smiled almost pitifully. "I do not apprehend danger," he said, "at least nothing unusual. But it happens that my business requires me to leave in the course of a few days at any rate, so, whether the eruption becomes fiercer or feebler, it will not matter to us. I have preparations to make, however, and I have no doubt you won't object to remain till all is ready for a start?"
"Oh, as to that," returned the youth, slightly hurt by the implied doubt as to his courage, "if you are willing to risk going off the earth like a skyrocket, I am quite ready to take my chance of following you!"
"An' Moses am de man," said the negro, smiting his broad chest with his fist, "what's ready to serve as a rocket-stick to bof, an' go up along wid you!"
The hermit made the nearest approach to a laugh which Nigel had yet seen, as he left the cave to undertake some of the preparations above referred to.
There is unquestionably a class of men—especially Englishmen—who are deeply imbued with the idea that the Universe in general, and our world in particular, has been created with a view to afford them what they call fun.
"It would be great fun," said an English commercial man to a friend who sat beside him, "to go and have a look at this eruption. They say it is Krakatoa which has broken out after a sleep of two centuries, and as it has been bursting away now for nearly a week, it is likely to hold on for some time longer. What would you say to charter a steamer and have a grand excursion to the volcano?"
The friend said he thought it would indeed be "capital fun!"
We have never been able to ascertain who these Englishmen were, but they must have been men of influence, or able to move men of influence, for they at once set to work and organised an excursion.
The place where this excursion was organised was Batavia. Although that city was situated in Java, nearly a hundred miles distant from Krakatoa, the inhabitants had not only heard distinctly the explosions of the volcano, but had felt some quakings of the earth and much rattling of doors and windows, besides a sprinkling of ashes, which indicated that the eruption, even in that eruptive region, was of unusual violence. They little imagined to what mighty throes the solid rocks of Krakatoa were yet to be subjected before those volcanic fires could find a vent. Meanwhile, as we have said, there was enough of the unusual in it to warrant our merchants in their anticipation of a considerable amount of fun.
A steamer was got ready; a number of sightseeing enthusiasts were collected, and they set forth on the morning of the 26th of May. Among these excursionists was our friend Captain David Roy—not that he was addicted to running about in search of "fun," but, being unavoidably thrown idle at the time, and having a poetical turn of mind—derived from his wife—he thought he could not do better than take a run to the volcano and see how his son was getting along.
The party reached the scene of the eruption on the morning of the 27th, having witnessed during the night several tolerably strong explosions, which were accompanied by earthquake shocks. It was found that Krakatoa and all the adjoining islands were covered with a fine white dust, like snow, and that the trees on the northern part of the former island and Varlaten had been to a great extent deprived of their leaves and branches by falling pumice, while those on Lang Island and Polish Hat, as well as those on the Peak of Rakata, had to a great extent escaped—no doubt owing to the prevailing direction of the wind.
It was soon seen that Perboewatan on Krakatoa was the cone in active eruption, and the steamer made for its neighbourhood, landing her party within a short distance of its base. Explosions were occurring at intervals of from five to ten minutes. Each explosion being accompanied by an uncovering of the molten lava in the vent, the overhanging steam-cloud was lighted up with a grand glow for a few seconds. Some of the party, who seemed to be authorities on such matters, estimated that the vapour-column rose to a height of nearly 10,000 feet, and that fragments of pumice were shot upwards to a height of 600 feet.
"That's a sign that the violence of the eruption is diminished," remarked the young merchant, who was in search of fun, as he prepared to wade ankle-deep in the loose pumice up the slopes of the cone.
"Diminished!" repeated our captain, who had fraternised much with this merchant during their short voyage. "If that's what you call diminishin', I shouldn't like to be here when it's increasin'."
"Pooh!" exclaimed the merchant, "that's nothing. I've seen, at other volcanoes, pieces of pumice blown up so high that they've been caught by the upper currents of the atmosphere and carried away in an opposite direction to the wind that was blowing below at the time. Ay, I believe that dust is sometimes blown miles up into the air."
As Captain Roy thought that the merchant was drawing the long bow he made no reply, but changed the subject by asking what was the height of Perboewatan.
"Three hundred feet or thereabouts," replied his friend.
"I hope my son will have the sense to clear out of the island if things look like gittin' worse," muttered the captain, as an unusually violent explosion shook the whole side of the cone.
"No fear of him," returned the merchant. "If he is visiting the hermit of Rakata, as you tell me, he'll be safe enough. Although something of a dare-devil, the hermit knows how to take care of himself. I'm afraid, however, that you'll not find it so easy to 'look up' your son as you seem to think. Just glance round at these almost impenetrable forests. You don't know what part of the island he may be in just now; and you might as well look for a needle in a bundle of hay as look for him there. He is probably at the other end of Krakatoa—four or five miles off—on the South side of Rakata, where the hermit's cave is supposed to be, for no one seems to be quite sure as to its whereabouts. Besides, you'll have to stick by the excursionists if you wish to return to Batavia."
Captain Roy paused for a moment to recover breath, and looking down upon the dense tropical forest that stretched between him and the Peak of Rakata, he shook his head, and admitted that the merchant was right. Turning round he addressed himself once more to the ascent of the cone, on the sides of which the whole excursion party now straggled and struggled, remarking, as he panted along, that hill-climbing among ashes and cinders didn't "come easy to a sea-farin' man."
Now, nothing was more natural than that Van der Kemp and his guest should be smitten with the same sort of desire which had brought these excursionists from Batavia. The only thing that we do not pretend to account for is the strange coincidence that they should have been so smitten, and had so arranged their plans, that they arrived at Perboewatan almost at the same time with the excursionists—only about half an hour before them!
Their preliminary walk, however, through the tangled, almost impassable, forest had been very slow and toilsome, and having been involved in its shadow from daybreak, they were, of course, quite unaware of the approach of the steamer or the landing of the excursion party.
"If the volcano seems quieting down," said Nigel to his host, "shall you start to-morrow?"
"Yes; by daybreak. Even if the eruption does not quiet down I must set out, for my business presses."
Nigel felt much inclined to ask what his business was, but there was a quiet something in the air of the hermit, when he did not choose to be questioned, which effectually silenced curiosity. Falling behind a little, till the negro came up with him, Nigel tried to obtain information from him, for he felt that he had a sort of right to know at least something about the expedition in which he was about to act a part.
"Do you know, Moses, what business your master is going about?" he asked, in a low voice.
"No more nor de man ob de moon, Massa Nadgel," said Moses, with an air at once so truthful and so solemn that the young man gave it up with a laugh of resignation.
On arriving at Perboewatan, and ascending its sides, they at last became aware of the approach of the excursion steamer.
"Strange," muttered the hermit, "vessels don't often touch here."
"Perhaps they have run short of water," suggested Nigel.
"Even if they had it would not be worth their while to stop here for that," returned the hermit, resuming the ascent of the cone after an intervening clump of trees had shut out the steamer from view.
It was with feelings of profound interest and considerable excitement that our hero stood for the first time on the top of a volcanic cone and gazed down into its glowing vent.
The crater might be described as a huge basin of 3000 feet in diameter. From the rim of this basin on which the visitors stood the sides sloped so gradually inward that the flat floor at the bottom was not more than half that diameter. This floor—which was about 150 feet below the upper edge—was covered with a black crust, and in the centre of it was the tremendous cavity—between one and two hundred feet in diameter—from which issued the great steam-cloud. The cloud was mixed with quantities of pumice and fragments of what appeared to be black glass. The roar of this huge vent was deafening and stupendous. If the reader will reflect on the wonderful hubbub that can be created even by a kitchen kettle when superheated, and on the exasperating shrieks of a steamboat's safety-valve in action, or the bellowing of a fog-horn, he may form some idea of the extent of his incapacity to conceive the thunderous roar of Krakatoa when it began to boil over.
When to this awful sound there were added the intermittent explosions, the horrid crackling of millions of rock-masses meeting in the air, and the bubbling up of molten lava—verily it did not require the imagination of a Dante to see in all this the very vomiting of Gehenna!
So amazed and well-nigh stunned was Nigel at the sights and sounds that he neither heard nor saw the arrival of the excursionists, until the equally awe-stricken Moses touched him on the elbow and drew his attention to several men who suddenly appeared on the crater-brim not fifty yards off, but who, like themselves, were too much absorbed with the volcano itself to observe the other visitors. Probably they took them for some of their own party who had reached the summit before them.
Nigel was yet looking at these visitors in some surprise, when an elderly nautical man suddenly stood not twenty yards off gazing in open-mouthed amazement, past our hero's very nose, at the volcanic fires.
"Hallo, Father!" shouted the one.
"Zounds! Nigel!" exclaimed the other.
Both men glared and were speechless for several seconds. Then Nigel rushed at the captain, and the captain met him half-way, and they shook hands with such hearty goodwill as to arrest in his operations for a few moments a photographer who was hastily setting up his camera!
Yes, science has done much to reveal the marvellous and arouse exalted thoughts in the human mind, but it has also done something to crush enthusiasts and shock the romantic. Veracity constrains us to state that there he was, with his tripod, and his eager haste, and his hideous black cloth, preparing to "take" Perboewatan on a "dry plate"! And he "took" it too! And you may see it, if you will, as a marvellous frontispiece to the volume by the "Krakatoa Committee"—a work which is apparently as exhaustive of the subject of Krakatoa as was the great explosion itself of those internal fires which will probably keep that volcano quiet for the next two hundred years.
But this was not the Great Eruption of Krakatoa—only a rehearsal, as it were.
"What brought you here, my son?" asked the captain, on recovering speech.
"My legs, father."
"Don't be insolent, boy."
"It's not insolence, father. It's only poetical licence, meant to assure you that I did not come by 'bus or rail though you did by steamer! But let me introduce you to my friend, Mr.–"
He stopped short on looking round, for Van der Kemp was not there.
"He goed away wheneber he saw de peepil comin' up de hill," said Moses, who had watched the meeting of father and son with huge delight. "But you kin interdooce me instead," he added, with a crater-like smile.
"True, true," exclaimed Nigel, laughing. "This is Moses, father, my host's servant, and my very good friend, and a remarkably free-and-easy friend, as you see. He will guide us back to the cave, since Van der Kemp seems to have left us."
"Who's Van der Kemp?" asked the captain.
"The hermit of Rakata, father—that's his name. His father was a Dutchman and his mother an English or Irish woman—I forget which. He's a splendid fellow; quite different from what one would expect; no more like a hermit than a hermit-crab, except that he lives in a cave under the Peak of Rakata, at the other end of the island. But you must come with us and pay him a visit. He will be delighted to see you."
"What! steer through a green sea of leaves like that?" said the captain, stretching his arm towards the vast forest that lay stretched out below them, "and on my legs, too, that have been used all their lives to a ship's deck? No, my son. I will content myself with this lucky meetin'. But, I say, Nigel, lad," continued the old man, somewhat more seriously, "what if the Peak o' Ra—Ra, what's-'is-name, should take to spoutin' like this one, an' you, as you say, livin' under it?"
"Ha! das 'zackly what I say," interposed Moses. "Das what I oftin says to massa, but he nebber answers. He only smile. Massa's not always so purlite as he might be!"
"There is no fear," said Nigel, "not at present, anyhow, for Van der Kemp says that the force of this eruption is diminishing—"
"It don't look much like it," muttered the captain, as the volcano at that moment gave vent to a burst which seemed like a sarcastic laugh at the hermit's opinion, and sent the more timid of the excursionists sprawling down the cinder-slope in great alarm.
"There's reason in what you say, father," said Nigel, when the diminution of noise rendered speech more easy; "and after all, as we start off on our travels to-morrow, your visit could not have been a long one."
"Where do you go first?" asked the captain.
"Not sure. Do you know, Moses?"
"No; no more 'n de man ob de moon. P'r'aps Borneo. He go dar sometimes."
At this point another roar from the volcano, and a shout from the leader of the excursionists to return on board, broke up the conference.
"Well, lad, I'm glad I've seen you. Don't forget to write your whereabouts. They say there's a lot o' wild places as well as wild men and beasts among them islands, so keep your weather-eye open an' your powder dry. Good-bye, Nigel. Take care of him, Moses, and keep him out o' mischief if ye can—which is more than ever I could. Good-bye, my boy."
"Good-bye, father."
They shook hands vigorously. In another minute the old seaman was sailing down the cinder-cone at the rate of fourteen knots an hour, while his son, setting off under the guidance of Moses towards a different point of the compass, was soon pushing his way through the tangled forest in the direction of the hermit's cave.
