Without waiting one second to deliberate, or question her, I set off at once upon my crutches, bounding and scurrying over the ground like a kangaroo by successive leaps, and hastening forward at a brisk rate which I should have thought beforehand no crutches on earth would possibly have compassed.

I reached the path, and turned hastily down it. The track was rough and difficult to traverse, even for an active man with both his legs to go upon; but for me, in my present halt and maimed condition, it was terribly hard and all but impracticable. Nevertheless, impelled by horror and fear for poor Kea's safety, T hurried along at a mad rate down the steep zig-zag, careless whether I fell or not in my wild haste, but eager only to prevent I knew not what awful heathenish catastrophe. I only prayed I might yet be in time to save her life. After many stumbles and hairbreadth escapes, rolling over and over with my crutches by my side, I found myself at last on the Floor of the Strangers, not far from the spot from which I had fallen before, but separated from it by a narrow chasm in the black basalt – a chasm, riven deep in the solid rock, and filled below, as I saw at once, with a fiery strait of white-hot lava.

It was full moonlight. Away off to the left, on the summit of the mountains, I saw the camp-fires of the naval eclipse parties. They were standing there, etched out distinctly against the pale sky-line; and I could recognize every one of their faces with ease through that clear air in the bright light of a tropical moon. But not a sign of Kea was to be seen anywhere. I looked anxiously round for her, and met no token anywhere. The old woman must surely have misdirected me on purpose. Fool that I was to have believed that hag! Kea and her party could hot have come this way at all towards the crater.

I saw my mistake. They had sent me wrong by deliberate design! At this supreme moment Kalaua had intentionally attempted to escape my notice.

Suddenly, as I looked and wondered in awe, a strange procession began slowly to descend the mountain side opposite, beyond the chasm, into the mouth of the crater. At its head came the man in the feather mask whom I had seen that day that I broke my leg on the edge of the precipice, and whom I now more distinctly than ever recognized as indeed Kalaua. There was no mistaking his gait and carriage. He stalked on proudly in front of the procession. Next after him, bearing rods with bunches of feathers fluttering in the breeze from their tops, came the four acolytes who had stood by his side that awful morning when he solemnly devoted me to the devouring volcano. Then four Hawaiian girls in white bridesmaids' dresses, with long garlands of oleanders strung round their necks, followed in order, two by two, waving their hands slowly above their heads, and chanting native himenés, as they call their long monotonous wails and dirges. My heart stood still as I saw with horror that Kea walked last, with downcast eyes, habited in her full bridal dress, and with the white veil falling round her in folds almost to her ankles. Behind her straggled a few hushed and awe-smitten spectators, half friendly assistants at this ghastly ceremony. I saw them all clearly but two hundred yards off, though the chasm in the rock with its red mass of molten lava below separated me from them far more effectually than a mile of intervening distance could possibly have done.

My first impulse was to cry aloud with indignation and horror. My next, for Kea's sake, was to hide myself at once behind a black jagged pinnacle of hardened lava before they caught sight of me. I did so almost as soon as the procession began to file slowly past the turn of the road; and it was by peering with caution round the corner of the pinnacle that I had observed them all as they descended two by two along the narrow foot-path.

Step after step they moved gradually down, to the long-drawn music of those unearthly himenés. Kea, in particular, glided on like a ghost, with downcast eyes and shrinking demeanour, yet not so much in the manner of a victim as of one who willingly and heroically devotes herself to some terrible end for the good of her country.

I knew she believed she was averting the wrath of Pélé, and I gasped with horror at her awful resolution.

Presently, the procession reached the Floor of the Strangers, on whose platform I myself was already crouched flat, though always separated from me by that terrific chasm; and advancing still to the lugubrious sound of these doleful himenés. Kalaua placed himself on the edge of the precipice, at the very spot where I myself had fallen over in pursuit of the butterfly. Kea, moving forward with slow and solemn steps, stood at his right hand, in her bridal dress, with her bloodless fingers clasped downward in front of her.

Then Kalaua began, in a strange cramped voice, to drone out some horrible dedicatory service. It sounded like the service he had droned out over myself on the morning of my accident: but I understood Hawaiian much better now, and could follow the words of his frightful litany with very little difficulty. Crouching behind the shadow of my broken lava pinnacle, I saw and heard the whole savage orgy like some unseen presence in that vast and self-lighted natural cathedral.

"Great Mother Pélé," Kalaua began, intoning his words on a single note and dividing his address into curious irregular verses – "Great Mother Pélé, who dwellest in the fire-lake, Queen of the Hawaiians, we, thy children, bow ourselves down in worship before thee.

"We assemble in thy temple, oh, thou, that delightest in the flesh of white-skinned chickens: we come into the outer threshold of thy house, oh, thou, that ridest on the red flaming surges.

"Sugar-cane, and tappa-cloth we offer to thy children: a bride, a wife, to thy favourite, to Maloka.

"Five sons thou hast borne in thy home, below; and one is humpbacked; thy favourite Maloka.

"A white man came from the lands beyond the sea: a pale-faced stranger; a wanderer to Hawaii.

"Of thy own accord thou chosest him a victim for thyself. He fell into thy trap. The white man's foot trod forbidden ground: the Floor of thy children, of thy children, the Hawaiians.

"In thy wrath, thou rosest to crumple him to ashes: thy flames soared upward like tongues of fire; dancing and surf-riding on the billows of flame, didst thou put forth thy red right hand to seize him.

"Come forward, Kea!"

The trembling girl came forward timidly.

Kalaua continued his awful chant once more, shaking his robe, and slowly dancing.

"A maiden rescued him: a mortal maiden. She stole the victim from the clutches of Pélé.

"No hand might save him against thy will: the force of a mortal avails not against the fiery might of a living goddess.

"Thou, Pélé, lettest him go for very contempt; thou gavest up the prey from thy fingers willingly.

"For such as her, a law is laid down.

"Victim for victim: life for life: whoever snatches an offering from Pélé, himself must satisfy the wrath of the goddess.

"Were it not so, thou wouldst deluge the land with lava; thou wouldst swallow the towns in the jaws of earthquakes: thou wouldst lick up the cane-fields with red tongues of fire.

"Thy son, Maloka, thy favourite, the humpbacked, he cried aloud to his mother for the maiden in marriage.

"'Give me this girl, he cried aloud, Oh Pélé: give me this maiden who snatched away thy victim.'

"Thou, Pélé, madest answer: 'My son, I give her thee.' Thou didst turn uneasily in thy flaming home, and threaten the Hawaiians with a deadly vengeance.

"See, we bring her: and we give her to Maloka; willingly, of her own accord, the maiden comes: on Maloka's night, arrayed as a bride in snow-white raiment, eager for her fate.

"Come forward, attendants!"

The bridesmaids, in their wreaths and garlands, stepped forward. I listened, horror-struck.

"Kea, do you take this god, Maloka, for your wedded lord?"

In a stifled voice, tremulous but firm, Kea answered aloud in her soft Hawaiian, "Kalaua, I take him."

"Maloka, do you take this girl, Kea, for your wedded wife?" And even as he spoke Kalaua cast something invisible from his hand with a dexterous throw, into the yawning abyss of lava below him. I then observed, for the very first time, that while the ceremony went on, the lake of fire had risen by slow degrees in the crater, and stood flush now with the Floor of the Hawaiians.

The volcano, as if in response to his direct question, gave a hideous roar, excited, I suppose, into some minor eruptive effort by the object he cast into it, which seemed to crash down and break upon a smouldering smoke-stack. It was as though the mountain had answered back in words, "Oh, priest, I take her."

Kalaua leaned forward, shaking and agitating his sacrificial robes. "At the stroke of midnight," he went on solemnly, "at the actual moment when Maloka the humpbacked climbs aloft to put out the moon, we will take the bride into the bridegroom's chamber. When Maloka the humpbacked puts out the moon, then leap, Kea, into the arms of your husband. See, see, how lovingly he stretches out his fiery arms for you in his chamber below there! When he rises in his might to put out the lamp that rides in heaven, then leap into his embrace. 'Tis the signal he gives you! Till then, sit still, and await your husband!"

Kea sat down by the edge of the precipice, on an isolated block of black basalt, and leaning her little chin on her small white hand, gazed below in awe and silent expectation on the flood of lava.

I knew, then, exactly what Kalaua meant. At the precise moment of the total eclipse, Kea was to leap into the abyss of the volcano.

I took out my watch, and consulted it anxiously, It wanted more than half-an-hour still to the actual point of absolute totality. I had that half-hour only to save Kea in. I saw her there seated on the edge of the abyss. I knew that the moment the moon was finally obscured, she would rise from her place, and leap madly forward of her own accord, into that sea of lava. She thought it her duty to appease the goddess. How to rescue her I could form no plan. Even if I rushed forth in my horror and managed by some miracle to span with a leap that yawning chasm that spread so wide between us, what was one lame white man among so many wild and heathenish Hawaiians? I could do nothing. I was helpless, powerless. If I set out to call the naval officers to my aid, long before I reached them, Kea's charred and mangled corpse would be floating, a mass of blackened ashes, on the fiery flood in the still rising crater. I trembled with horror. And yet – and yet —

And yet I must do something to rescue Kea!

CHAPTER XIII

On the summit above, all unconscious of this ghastly and incredible tragedy taking place within a stone's throw of where they stood, I could see Frank and the men from the gunboat, busying themselves quietly with their eclipse arrangements, as if nothing more terrible than an ordinary volcanic outburst were proceeding anywhere in their immediate neighbourhood. The bright tropical moonlight revealed their forms and faces to me almost as clearly as the noonday sun: I could even distinguish the play of their features, and notice how Frank was laughing and talking, with his usual good-humoured boyish merriment, to the officers and sailors. The contrast was nothing short of appalling. On one side, those easy-going sea-faring men, with their finished instruments of modern science, calmly engaged in observing and noting down the face of our distant satellite: on the other side, that group of stern and sombre half-heathen Hawaiians, occupied in the horrible and cruel rites of an effete and proscribed barbaric religion. Never, I thought to myself, did civilization and savagery stand closer together, cheek by jowl: never did the two extremes of human thought and human sentiment come in nearer contact, all unconscious and heedless one of the other. For neither party could see round the corner of jagged rock that overhung and divided them; I alone, looking either way up and down the crater, could take in both groups at a single glance – the scientific observers and the wild heathen priests of that human sacrifice.

But how to attract the notice of the Englishmen! If only I could manage to catch Frank's face! If only I could fling up my arms and sign to him to come! But he would not look! It was terrible! It was agonizing!

Suddenly, an inspiration seized me unawares. The heliograph to the rescue! I might signal to him by the moonlight. One chance yet left! My mirror! My mirror!

I felt for it in my pocket with trembling fingers. One moment of hope. Then an abyss of despair. I had left it at home by the sofa at Kalaua's. That chance was fruitless.

To have made my way back for it would have been of little avail. I could not fail in that case to attract Kalaua's keen attention, as I hobbled painfully in the broad moonlight up the zig-zag path: and to attract attention under existing circumstances would probably mean all the sooner to hasten poor trembling Kea's impending fate. I must think of some other means of communicating with Frank. I must find some less obtrusive and dangerous way of calling the sailors and officers to our assistance.

How short a time still remained to us! I took out my watch and gazed at it hopelessly.

In another burst of inspiration, then, I saw my way clear. A mirror! A mirror! all ready to hand! I could signal still! I could call their attention!

My watch was a gold one – a naval chronometer: the inside of the case was burnished and bright. I held it up straight in the bright beams of the moon, and as Frank's face turned for a moment in the direction where I stood, or rather crouched under cover of the pinnacle, I flashed the light full in his eyes from the reflecting surface. Thank heaven! Thank heaven! he started and observed it. I signalled three rapid flashes for attention. Frank flashed me back, yes, from his own pocket mirror. My hands shook so that I could hardly hold the watch aright: but with tremulous fingers I managed somehow to spell out the words, "Come quick. Bring sailors. Steal cautiously round the dark corner. There's foul play on. Kalaua means to make Kea leap into the crater as a bride to Pélé's son at the moment of totality."

In a second, I saw that Frank and the officers had taken it all in in its full ghastliness, and that, if time enough remained, Kea might yet be saved from that awful death in the fiery abysses. Without one moment's delay their men seized the horses, and leaving one or two, officers alone to continue the observations, dashed wildly down the ravine, and into the gloom of the gully.

Then, for a few minutes more, I lost sight of them entirely.

When they emerged again to view, on the Floor of the Strangers, they had left their horses, and, headed by Frank in his white jacket, were creeping cautiously, unperceived, under cover of the broken masses of lava, round the sharp corner of the jutting platform. My heart bounded as I saw them approach. There was still some chance, then, of saving Kea!

Had she been my own sister I could not have felt the suspense more awful.

As we gazed below we saw, to our dismay, that the lake of fire was still tossing and rolling with wild wreathing billows, and that it had risen visibly several feet in the last few minutes.

While we still looked, the moon's face began slowly to darken. The eclipse had commenced. We had only a quarter of an hour yet to the period of totality.

In a few short words, I explained to Frank and the sailors he had brought with him the entire situation in all its gravity. I told them all I had seen and heard; and their own eyes confirmed my report: for there stood Kea full in view, round the corner of the pinnacle, beyond the open chasm, in her white dress, with her hands clasped in inarticulate prayer, and her pale face turned up appealingly towards the cold moonlight. She had but a quarter of an hour left to live. Yet near as we were to her, it would have taken us more than fifty minutes to ride round the crater by the outer rim to the only practicable path on the other side of the chasm.

"What are we to do?" I cried, in my horror, though in a low voice, for it was necessary above all things not to arouse the Hawaiians' quick attention.

"We must cross the chasm somehow," the eldest officer of the party answered at once. "We can't let the poor girl be sacrificed before our very eyes."

"If we only had a rope, and could once get it fastened on the other side, we might sling ourselves across, hand over hand," Frank suggested eagerly.

"We have rope, lots of it, on my saddle over yonder," the officer answered. "But we can't get it fastened. If only the chasm were narrow enough to leap! But it's quite impossible. No athlete on earth could ever jump it."

"Stop!" Frank cried. "The bamboo! The bamboo! – I had a big bamboo down here the other day, stirring up lava in a liquid pool in the small craters. There it is – over yonder. I think with that – "

He said no more, but creeping over for the bamboo, crawled noiselessly on with it to the edge of the chasm. We all followed him on our hands and knees, skulking behind the pinnacles, and concealed from the Hawaiians by the rough lava-masses. I seemed to forget my half-mended leg in the excitement of the moment, and to crawl along as easily and as quickly as any of them. On the very edge of the deep fissure, now boiling below with liquid fire, Frank laid across the bamboo from cliff to cliff, so that it hung, a frail bridge, across that yawning abyss of sulphurous vapour. With great difficulty, he thrust it home on the far side into a honey-combed mass of crumbling scoriae lava. "Now stand, you fellows, on the end," he said, "to give it weight and keep me from slipping. I'm the lightest of the lot: it'll bear me, I suppose, if it'll bear anybody. I'm going to cross it, hand over hand, and take a rope with me for you others to come over by. If it breaks, I shall fall into the lava below. No matter: it's jolly white hot down there now; it'd frizzle me up, if it came to the worst, before I could feel it."

The sailors brought all their weight to bear upon the loose end. I knelt by myself, breathless with suspense, to see the result of this mad experiment. The bamboo was frail and supple indeed: if it broke, as Frank said, all would be up with him. But Frank was too brave to heed much for that. He tied the rope round his waist in a running noose, caught hold of the bamboo with both his hands, and swinging himself off the edge with a quiet and gentle swaying motion, so as to lessen as far as possible the strain of that slender bridge, hung one moment like a gymnast, from a trapeze, suspended between the sky and the gulf of liquid lava.

It was a terrible moment. All eager with excitement, we leaned over the abyss, and watched him rapidly but quietly passing hand over hand across that frightful chasm. As he reached the middle, the bamboo for one indivisible second of time bent ominously down under his light weight. Would it yield? Would it crack? If so, the next instant we should see him falling, a lost life, into that hideous strait of liquid fire. For half a throb of the heart, our agony of doubt and suspense was unspeakable. Next instant, he had passed in safety the central point; the weight was easier; the faithful bamboo curved slowly up again.

We breathed more freely. He had reached the far end; he was grasping the cliff, the further cliff, in eager confidence, with that brave young hand of his. The lava was loose; all bubbly with holes like a piece of rotten pumice-stone. "Frank, Frank," I cried in a low voice, but beside myself with terror, "take care how you trust it. The stuff's all dry. It never can bear you. Don't try to grasp it!"

"All right," Frank answered low, as he struggled on. "There's no foothold anywhere near the edge. I must go in for a somersault. Thank goodness that gymnasium work I used to hate so has done something for me unexpectedly at last."

As he spoke, he vaulted with a light leap on his hands up the edge of the precipice. The next thing we knew, he was standing, safe and sound, with the rope round his waist, a living soul, on the further brink beyond the chasm.

A sigh of relief burst simultaneously from all our lips. "Now, quick!" the officer cried. "Not a moment to be lost! Swing yourselves over, men, and make haste about it!"

Frank held the end of rope in both hands firmly, twisting it for greater security twice round his body: and the slenderest of the sailors, trusting himself the first to this safer bridge, crossed over the chasm with the ease and rapidity due to long practice on the masts and rigging. As soon as he had landed unhurt on the far side, he helped Frank to hold the end of the rope; and one by one his five companions and the officer last of all made good their passage in the self-same manner. I alone was left to keep up touch and facilitate their return to the hither side; for we felt we must probably fight for Kea. Our plan was to seize her by main force, before the natives were aware, retire with her to our horses, and ride down at all speed to the Hornet at Hilo.

"Now, look sharp: make a dash for it!" the officer said, in a muffled voice. "Out into the open, and seize the girl at once! Never mind the men. Carry her off in your arms before they know what's happening, and back here again to the rope immediately."

I stood and watched on the further bank of that fiery strait. The moon's light meanwhile had been growing each instant dimmer and dimmer. The greater part of the orb was already obscured. The moment of totality was rapidly approaching. Kea, warned by a word from her uncle, stood up in her bridal dress and faced the awful flood of surging lava. Kalaua, by her side, began once more to drone out in long notes his monotonous chant. He flung a handful of taro, with a solemn incantation, into the mouth of the volcano. "See, Pélé," he cried, "we bring thee thy daughter-in-law. See, Maloka, we bring thee thy chosen bride. At the stroke of midnight, at the appointed hour, thou hast put out the lamp in heaven, the moon. This is thy signal: we mortals obey it. O humpbacked favourite of Pélé the long-haired, the bride will go into the bridegroom's chamber. – Maloka, hold up thy hands for thy handmaid! leap, Kea, leap, into the arms of your husband!"

I looked and trembled. Kea stepped forward with marvellous courage. Through the dim light of the ruddy volcanic fires I could see her draw back her white veil from her face, and make as though she would meet some lovers embraces. Then the last corner of the moon disappeared all at once in darkness from my sight, and for half a moment, at that critical point, I saw and heard nothing with distinctness or certainty.

Next instant, as if by magic, a weird red glare illumined the scene. Great arms of fire lunged forth spasmodically from the open crater. Maloka had leaped forward with his scorching hands, to claim his bride in fiery wedlock. The eruption had at last begun in real earnest. Huge volumes of flame darted up with commingled black smoke towards the vault of heaven. A lurid light hung upon the massive clouds overhead. Stones and ashes and cinders fell wildly around us. The crater had broken loose in its fiercest might. The rivers of liquid fire were welling up all round and bursting their bounds with majestic grandeur.

And in the midst of all, by the uncertain light of that deep red glare, I could just see Frank and the friendly sailors bearing off Kea in her bridal robe, half fainting, half unwilling, before the very eyes of the astonished and amazed Hawaiians. Our party had rushed upon them from behind, unawares, at the very first instant of total eclipse, and seized her in their arms, in the act to jump, from the circling ring of baffled natives.

Thank heaven, then, they had been in time; in time to save her from the cruel volcano and the crueller superstition of her heathen ancestors.

"Back, now, back, to the chasm and your horses!" the officer cried in a tune of command, at the top of his voice, as Kalaua and the natives, recovering after a moment from their first shock of surprise, and gathering together into an angry knot, began to show signs of attempting an organized resistance. "Carry off the girl between you, there, at the top of your speed. No time to lose! The lava's rising." He pointed his revolver. "And if one of you heathen brown fellows come a single step nearer," he added with a menace, "I'll put a bullet through his ugly black head, as soon as look at him."

Kalaua leaped forward with a wild and almost inarticulate cry of rage and disappointment. "Seize them, friends," he shrieked aloud in his hoarse Hawaiian. "Kill them! Tear them to pieces! How dare they interfere with the bridals of Maloka?" Bat even as he spoke, a river of lava burst suddenly forth from the mouth of the seething crater, and spread a broad stream of liquid fire between the infuriated natives and the little band of Kea's gallant protectors.

"Run, run," Kalaua cried. "Down the other road! By the black rocks! Intercept them at the gulley. Kill them! kill them! They're Pélé's enemies! However you do it, kill them, kill them!"

The officer, unheeding their savage threats, stalked on to the chasm, and pointed firmly but quietly to the rope that still spanned it. Kea, dazed and frightened, yet graceful and light of limb as ever, clasping it hard in her small fair hands, swung herself across to my side with native ease, while the sailors held the ends of the cable on the bank opposite. Then one by one the others followed swiftly in turn, with admirable discipline, in spite of the shower of ashes, till only Frank was left by himself beyond the deep abyss of boiling lava.

"How will he ever get over?" I cried, looking across at him in alarm and terror.

"Oh, don't be afraid, old fellow!" Frank shouted back cheerily. "Leave that to me! I'm as right as ninepence. Thank goodness, I can hang from a rope like a monkey!" And with a hasty movement, he began to roll the end of the cable tight around his waist and to tie it firmly in a slip-knot to his sturdy shoulders.

How he could ever drop himself down so steep an abyss with flame below, I had no notion. On the other hand, I knew he dared not trust the bamboo again. It had bent already too severely with his weight, almost indeed to the point of breaking; and half charred as it now was with the constant heat ascending for ever from that subterranean furnace, it would no doubt have snapped short in the middle by this time, if he had been foolish enough to attempt crossing by its aid a second time over the few yards of chasm that intervened to divide us.

Frank however had a device of his own. Planting his feet hard against the edge of the precipice, he swung himself off like a monkey, with the rope grasped hard in his two hands; and even as he fell, kicking off from the side, he gripped it quickly hand over hand, till he brought himself up with wonderful agility level with the opposite side where we were all standing. Half a dozen stout arms were extended at once to pull him safe to solid land; and in another moment we all stood secure, with Kea in our midst, a recovered party, on the brink of the crater, undeterred by anything more serious in its way than an ordinary everyday volcanic outburst.

"Off to the horses!" the officer cried aloud; and before I knew what was happening, two of the sailors had seized me in their arms, and were hurrying me away at a break-neck pace up the steep zig-zag to the level of the summit.

In the ravine, we came, sure enough, upon the horses, tethered and guarded by a couple of sailors. "Mount," the officer cried with military promptitude: and the men mounted, not exactly, I must confess, with the ease or grace of cavalry orderlies. I mounted myself, too, with what skill I could command, taking into consideration that broken leg of mine; and giving the trusty little ponies their heads, we rode at full speed in breathless haste, but in long Indian file down the narrow bridle path to the base of the mountain.

I knew well the gully where the two roads joined, and where Kalaua had threatened to meet us in hostile array with his proscribed band of heathen followers. It was an ugly spot, with great overhanging rocks to defend the pass, and if they got there first, I knew we should have to fight them for possession of Kea. All depended now upon the swiftness and sureness of foot of our ponies. To be sure, we were mounted, while Kalaua and his party were all on foot; but then, most of us had been greatly delayed by the necessity for recrossing the chasm on the rope bridge in order to get at our path and our horses; and even apart from this unavoidable stoppage, very few ponies, at the best of times, can cover the ground faster than an unimpeded Hawaiian. Those fellows can run like a deer or greyhound. I trembled for the result if they held the rocks above the fort in full force. They could hurl down stones upon us from the heights with infinite ease, crush us like locusts as we passed beneath them: even fire-arms there would be useless against a party that held the pass in any numbers.

On, on, we rode, in fear and trembling. The volcano now was all in full blast. Ashes and pumice stone kept falling around us. Smoke and steam obscured our way. But the dangers of nature frightened us little in comparison; what we dreaded most was the desperate onslaught of the enraged Hawaiians.

As we drew near the fort however I breathed again more freely. Not a sign of Kalaua was anywhere to be seen. We rode along, cautiously, under the overhanging rocks. No Hawaiian showed his grim black head above or below us. Then Kea, with a shriek, guessed in a moment exactly what had happened. "The lava has overwhelmed them!" she cried, clasping her hands together in girlish trepidation. "They are dead! They are dead! My uncle! My people! Pélé will not be robbed of her victim at any rate. The lava has burst forth in one great flood and swallowed them."
