The Lost World

Chapter IX - Who Could Have Foreseen It?

A dreadful thing has happened to us. Who could have foreseen it? I cannot foresee any end to our troubles. It may be that we are condemned to spend our whole lives in this strange, inaccessible place. I am still so confused that I can hardly think clearly of the facts of the present or of the chances of the future. To my astounded senses the one seems most terrible and the other as black as night.

No men have ever found themselves in a worse position; nor is there any use in disclosing to you our exact geographical situation and asking our friends for a relief party. Even if they could send one, our fate will in all human probability be decided long before it could arrive in South America.

We are, in truth, as far from any human aid as if we were in the moon. If we are to win through, it is only our own qualities which can save us. I have as companions three remarkable men, men of great brain-power and of unshaken courage. There lies our one and only hope. It is only when I look upon the untroubled faces of my comrades that I see some glimmer through the darkness. Outwardly I trust that I appear as unconcerned as they. Inwardly I am filled with apprehension.

Let me give you, with as much detail as I can, the sequence of events which have led us to this catastrophe.

When I finished my last letter I stated that we were within seven miles from an enormous line of ruddy cliffs, which encircled, beyond all doubt, the plateau of which Professor Challenger spoke. Their height, as we approached them, seemed to me in some places to be greater than he had stated—running up in parts to at least a thousand feet—and they were curiously striated, in a manner which is, I believe, characteristic of basaltic upheavals. Something of the sort is to be seen in Salisbury Crags at Edinburgh. The summit showed every sign of a luxuriant vegetation, with bushes near the edge, and farther back many high trees. There was no indication of any life that we could see.

That night we pitched our camp immediately under the cliff—a most wild and desolate spot. The crags above us were not merely perpendicular, but curved outwards at the top, so that ascent was out of the question. Close to us was the high, thin pinnacle of rock which I believe I mentioned earlier in this narrative. It is like a broad red church spire, the top of it being level with the plateau, but a great chasm gaping between. On the summit of it there grew one high tree. Both pinnacle and cliff were comparatively low—some five or six hundred feet, I should think.

"It was on that," said Professor Challenger, pointing to this tree, "that the pterodactyl was perched. I climbed half-way up the rock before I shot him. I am inclined to think that a good mountaineer like myself could ascend the rock to the top, though he would, of course, be no nearer to the plateau when he had done so."

As Challenger spoke of his pterodactyl I glanced at Professor Summerlee, and for the first time I seemed to see some signs of a dawning credulity and repentance. There was no sneer upon his thin lips, but, on the contrary, a grey, drawn look of excitement and amazement. Challenger saw it, too, and revelled in the first taste of victory.

"Of course," said he, with his clumsy and ponderous sarcasm, "Professor Summerlee will understand that when I speak of a pterodactyl I mean a stork—only it is the kind of stork which has no feathers, a leathery skin, membranous wings, and teeth in its jaws." He grinned and blinked and bowed until his colleague turned and walked away.

In the morning, after a frugal breakfast of coffee and manioc—we had to be economical of our stores--we held a council of war as to the best method of ascending to the plateau above us.

Challenger presided with a solemnity as if he were the Lord Chief Justice on the Bench. Picture him seated upon a rock, his absurd boyish straw hat tilted on the back of his head, his supercilious eyes dominating us from under his drooping lids, his great black beard wagging as he slowly defined our present situation and our future movements.

Beneath him you might have seen the three of us—myself, sunburnt, young, and vigorous after our open-air tramp; Summerlee, solemn but still critical, behind his eternal pipe; Lord John, as keen as a razor-edge, with his supple, alert figure leaning upon his rifle, and his eager eyes fixed eagerly upon the speaker. Behind us were grouped the two swarthy half-breeds and the little knot of Indians, while in front and above us towered those huge, ruddy ribs of rocks which kept us from our goal.

"I need not say," said our leader, "that on the occasion of my last visit I exhausted every means of climbing the cliff, and where I failed I do not think that anyone else is likely to succeed, for I am something of a mountaineer. I had none of the appliances of a rock-climber with me, but I have taken the precaution to bring them now. With their aid I am positive I could climb that detached pinnacle to the summit; but so long as the main cliff overhangs, it is vain to attempt ascending that. I was hurried upon my last visit by the approach of the rainy season and by the exhaustion of my supplies. These considerations limited my time, and I can only claim that I have surveyed about six miles of the cliff to the east of us, finding no possible way up. What, then, shall we now do?"

"There seems to be only one reasonable course," said Professor Summerlee. "If you have explored the east, we should travel along the base of the cliff to the west, and seek for a practicable point for our ascent."

"That's it," said Lord John. "The odds are that this plateau is of no great size, and we shall travel round it until we either find an easy way up it, or come back to the point from which we started."

"I have already explained to our young friend here," said Challenger (he has a way of alluding to me as if I were a school child ten years old), "that it is quite impossible that there should be an easy way up anywhere, for the simple reason that if there were the summit would not be isolated, and those conditions would not obtain which have effected so singular an interference with the general laws of survival. Yet I admit that there may very well be places where an expert human climber may reach the summit, and yet a cumbrous and heavy animal be unable to descend. It is certain that there is a point where an ascent is possible."

"How do you know that, sir?" asked Summerlee, sharply.

"Because my predecessor, the American Maple White, actually made such an ascent. How otherwise could he have seen the monster which he sketched in his notebook?"

"There you reason somewhat ahead of the proved facts," said the stubborn Summerlee. "I admit your plateau, because I have seen it; but I have not as yet satisfied myself that it contains any form of life whatever."

"What you admit, sir, or what you do not admit, is really of inconceivably small importance. I am glad to perceive that the plateau itself has actually obtruded itself upon your intelligence." He glanced up at it, and then, to our amazement, he sprang from his rock, and, seizing Summerlee by the neck, he tilted his face into the air. "Now, sir!" he shouted, hoarse with excitement. "Do I help you to realize that the plateau contains some animal life?"

I have said that a thick fringe of green overhung the edge of the cliff. Out of this there had emerged a black, glistening object. As it came slowly forth and overhung the chasm, we saw that it was a very large snake with a peculiar flat, spade-like head. It wavered and quivered above us for a minute, the morning sun gleaming upon its sleek, sinuous coils. Then it slowly drew inwards and disappeared.

Summerlee had been so interested that he had stood unresisting while Challenger tilted his head into the air. Now he shook his colleague off and came back to his dignity.

"I should be glad, Professor Challenger," said he, "if you could see your way to make any remarks which may occur to you without seizing me by the chin. Even the appearance of a very ordinary rock python does not appear to justify such a liberty."

"But there is life upon the plateau all the same," his colleague replied in triumph. "And now, having demonstrated this important conclusion so that it is clear to anyone, however prejudiced or obtuse, I am of opinion that we cannot do better than break up our camp and travel to westward until we find some means of ascent."

The ground at the foot of the cliff was rocky and broken so that the going was slow and difficult. Suddenly we came, however, upon something which cheered our hearts. It was the site of an old encampment, with several empty Chicago meat tins, a bottle labelled "Brandy," a broken tin-opener, and a quantity of other travellers' débris. A crumpled, disintegrated newspaper revealed itself as the Chicago Democrat, though the date had been obliterated.

"Not mine," said Challenger. "It must be Maple White's."

Lord John had been gazing curiously at a great tree-fern which overshadowed the encampment. "I say, look at this," said he. "I believe it is meant for a sign-post."

A slip of hard wood had been nailed to the tree in such a way as to point to the westward.

"Most certainly a sign-post," said Challenger. "What else? Finding himself upon a dangerous errand, our pioneer has left this sign so that any party which follows him may know the way he has taken. Perhaps we shall come upon some other indications as we proceed."

We did indeed, but they were of a terrible and most unexpected nature. Immediately beneath the cliff there grew a considerable patch of high bamboo, like that which we had traversed in our journey. Many of these stems were twenty feet high, with sharp, strong tops, so that even as they stood they made formidable spears. We were passing along the edge of this cover when my eye was caught by the gleam of something white within it. Thrusting in my head between the stems, I found myself gazing at a fleshless skull. The whole skeleton was there, but the skull had detached itself and lay some feet nearer to the open.

With a few blows from the machetes of our Indians we cleared the spot and were able to study the details of this old tragedy. Only a few shreds of clothes could still be distinguished, but there were the remains of boots upon the bony feet, and it was very clear that the dead man was a European. A gold watch by Hudson, of New York, and a chain which held a stylographic pen, lay among the bones. There was also a silver cigarette-case, with "J. C., from A. E. S.," upon the lid. The state of the metal seemed to show that the catastrophe had occurred no great time before.

"Who can he be?" asked Lord John. "Poor devil! every bone in his body seems to be broken."

"And the bamboo grows through his smashed ribs," said Summerlee. "It is a fast-growing plant, but it is surely inconceivable that this body could have been here while the canes grew to be twenty feet in length."

"As to the man's identity," said Professor Challenger, "I have no doubt whatever upon that point. As I made my way up the river before I reached you at the fazenda I instituted very particular inquiries about Maple White. At Para they knew nothing. Fortunately, I had a definite clew, for there was a particular picture in his sketch-book which showed him taking lunch with a certain ecclesiastic at Rosario. This priest I was able to find, and though he proved a very argumentative fellow, who took it absurdly amiss that I should point out to him the corrosive effect which modern science must have upon his beliefs, he none the less gave me some positive information. Maple White passed Rosario four years ago, or two years before I saw his dead body. He was not alone at the time, but there was a friend, an American named James Colver, who remained in the boat and did not meet this ecclesiastic. I think, therefore, that there can be no doubt that we are now looking upon the remains of this James Colver."

"Nor," said Lord John, "is there much doubt as to how he met his death. He has fallen or been chucked from the top, and so been impaled. How else could he come by his broken bones, and how could he have been stuck through by these canes with their points so high above our heads?"

A hush came over us as we stood round these shattered remains and realized the truth of Lord John Roxton's words. The beetling head of the cliff projected over the cane-brake. Undoubtedly he had fallen from above. But had he fallen? Had it been an accident? Or——already ominous and terrible possibilities began to form round that unknown land.

We moved off in silence, and continued to coast round the line of cliffs, which were as even and unbroken as some of those monstrous Antarctic ice-fields which I have seen depicted as stretching from horizon to horizon and towering high above the mast-heads of the exploring vessel. In five miles we saw no rift or break. And then suddenly we perceived something which filled us with new hope. In a hollow of the rock, protected from rain, there was drawn a rough arrow in chalk, pointing still to the westwards.

"Maple White again," said Professor Challenger. "He had some presentiment that worthy footsteps would follow close behind him."

"He had chalk, then?"

"A box of coloured chalks was among the effects I found in his knapsack. I remember that the white one was worn to a stump."

"That is certainly good evidence," said Summerlee. "We can only accept his guidance and follow on to the westward."

We had proceeded some five more miles when again we saw a white arrow upon the rocks. It was at a point where the face of the cliff was for the first time split into a narrow cleft. Inside the cleft was a second guidance mark, which pointed right up it with the tip somewhat elevated, as if the spot indicated were above the level of the ground.

It was a solemn place, for the walls were so gigantic and the slit of blue sky so narrow and so obscured by a double fringe of verdure, that only a dim and shadowy light penetrated to the bottom. We had had no food for many hours, and were very weary with the stony and irregular journey, but our nerves were too strung to allow us to halt. We ordered the camp to be pitched, however, and, leaving the Indians to arrange it, we four, with the two half-breeds, proceeded up the narrow gorge.

It was not more than forty feet across at the mouth, but it rapidly closed until it ended in an acute angle, too straight and smooth for an ascent. Certainly it was not this which our pioneer had attempted to indicate. We made our way back—the whole gorge was not more than a quarter of a mile deep—and then suddenly the quick eyes of Lord John fell upon what we were seeking. High up above our heads, amid the dark shadows, there was one circle of deeper gloom. Surely it could only be the opening of a cave.

The base of the cliff was heaped with loose stones at the spot, and it was not difficult to clamber up. When we reached it, all doubt was removed. Not only was it an opening into the rock, but on the side of it there was marked once again the sign of the arrow. Here was the point, and this the means by which Maple White and his ill-fated comrade had made their ascent.

We were too excited to return to the camp, but must make our first exploration at once. Lord John had an electric torch in his knapsack, and this had to serve us as light. He advanced, throwing his little clear circlet of yellow radiance before him, while in single file we followed at his heels.

The cave had evidently been water-worn, the sides being smooth and the floor covered with rounded stones. It was of such a size that a single man could just fit through by stooping. For fifty yards it ran almost straight into the rock, and then it ascended at an angle of forty-five. Presently this incline became even steeper, and we found ourselves climbing upon hands and knees among loose rubble which slid from beneath us. Suddenly an exclamation broke from Lord Roxton.

"It's blocked!" said he.

Clustering behind him we saw in the yellow field of light a wall of broken basalt which extended to the ceiling.

"The roof has fallen in!"

In vain we dragged out some of the pieces. The only effect was that the larger ones became detached and threatened to roll down the gradient and crush us. It was evident that the obstacle was far beyond any efforts which we could make to remove it. The road by which Maple White had ascended was no longer available.

Too much cast down to speak, we stumbled down the dark tunnel and made our way back to the camp.

One incident occurred, however, before we left the gorge, which is of importance in view of what came afterwards.

We had gathered in a little group at the bottom of the chasm, some forty feet beneath the mouth of the cave, when a huge rock rolled suddenly downwards—and shot past us with tremendous force. It was the narrowest escape for one or all of us. We could not ourselves see whence the rock had come, but our half-breed servants, who were still at the opening of the cave, said that it had flown past them, and must therefore have fallen from the summit. Looking upwards, we could see no sign of movement above us amidst the green jungle which topped the cliff. There could be little doubt, however, that the stone was aimed at us, so the incident surely pointed to humanity—and malevolent humanity—upon the plateau.

We withdrew hurriedly from the chasm, our minds full of this new development and its bearing upon our plans. The situation was difficult enough before, but if the obstructions of Nature were increased by the deliberate opposition of man, then our case was indeed a hopeless one. And yet, as we looked up at that beautiful fringe of verdure only a few hundreds of feet above our heads, there was not one of us who could conceive the idea of returning to London until we had explored it to its depths.

On discussing the situation, we determined that our best course was to continue to coast round the plateau in the hope of finding some other means of reaching the top. The line of cliffs, which had decreased considerably in height, had already begun to trend from west to north, and if we could take this as representing the arc of a circle, the whole circumference could not be very great. At the worst, then, we should be back in a few days at our starting-point.

We made a march that day which totalled some two-and-twenty miles, without any change in our prospects. I may mention that our aneroid shows us that in the continual incline which we have ascended since we abandoned our canoes we have risen to no less than three thousand feet above sea-level. Hence there is a considerable change both in the temperature and in the vegetation. We have shaken off some of that horrible insect life which is the bane of tropical travel. A few palms still survive, and many tree-ferns, but the Amazonian trees have been all left behind. It was pleasant to see the convolvulus, the passion-flower, and the begonia, all reminding me of home, here among these inhospitable rocks. There was a red begonia just the same colour as one that is kept in a pot in the window of a certain villa in Streatham—but I am drifting into private reminiscence.

That night—I am still speaking of the first day of our circumnavigation of the plateau—a great experience awaited us, and one which for ever set at rest any doubt which we could have had as to the wonders so near us.

You will realize as you read it, my dear Mr. McArdle, and possibly for the first time that the paper has not sent me on a wild-goose chase, and that there is inconceivably fine copy waiting for the world whenever we have the Professor's leave to make use of it. I shall not dare to publish these articles unless I can bring back my proofs to England, or I shall be hailed as the journalistic Munchausen of all time. I have no doubt that you feel the same way yourself, and that you would not care to stake the whole credit of the Gazette upon this adventure until we can meet the chorus of criticism and scepticism which such articles must of necessity elicit. So this wonderful incident, which would make such a headline for the old paper, must still wait its turn in the editorial drawer.

And yet it was all over in a flash, and there was no sequel to it, save in our own convictions.

What occurred was this. Lord John had shot an ajouti—which is a small, pig-like animal—and, half of it having been given to the Indians, we were cooking the other half upon our fire. There is a chill in the air after dark, and we had all drawn close to the blaze. The night was moonless, but there were some stars, and one could see for a little distance across the plain. Well, suddenly out of the darkness, out of the night, there swooped something with a swish like an aeroplane. The whole group of us were covered for an instant by a canopy of leathery wings, and I had a momentary vision of a long, snake-like neck, a fierce, red, greedy eye, and a great snapping beak, filled, to my amazement, with little, gleaming teeth. The next instant it was gone—and so was our dinner. A huge black shadow, twenty feet across, skimmed up into the air; for an instant the monster wings blotted out the stars, and then it vanished over the brow of the cliff above us. We all sat in amazed silence round the fire, like the heroes of Virgil when the Harpies came down upon them. It was Summerlee who was the first to speak.

"Professor Challenger," said he, in a solemn voice, which quavered with emotion, "I owe you an apology. Sir, I am very much in the wrong, and I beg that you will forget what is past."

It was handsomely said, and the two men for the first time shook hands. So much we have gained by this clear vision of our first pterodactyl. It was worth a stolen supper to bring two such men together.

But if prehistoric life existed upon the plateau it was not superabundant, for we had no further glimpse of it during the next three days. During this time we traversed a barren and forbidding country, which alternated between stony desert and desolate marshes full of many wild-fowl, upon the north and east of the cliffs. From that direction the place is really inaccessible, and, were it not for a hardish ledge which runs at the very base of the precipice, we should have had to turn back. Many times we were up to our waists in the slime and blubber of an old, semi-tropical swamp. To make matters worse, the place seemed to be a favourite breeding-place of the Jaracaca snake, the most venomous and aggressive in South America. Again and again these horrible creatures came writhing and springing towards us across the surface of this putrid bog, and it was only by keeping our shot-guns for ever ready that we could feel safe from them. One funnel-shaped depression in the morass, of a livid green in colour from some lichen which festered in it, will always remain as a nightmare memory in my mind. It seems to have been a special nest of these vermin, and the slopes were alive with them, all writhing in our direction, for it is a peculiarity of the Jaracaca that he will always attack man at first sight. There were too many for us to shoot, so we fairly took to our heels and ran until we were exhausted. I shall always remember as we looked back how far behind we could see the heads and necks of our horrible pursuers rising and falling amid the reeds. Jaracaca Swamp we named it in the map which we are constructing.

The cliffs upon the farther side had lost their ruddy tint, being chocolate-brown in colour; the vegetation was more scattered along the top of them, and they had sunk to three or four hundred feet in height, but in no place did we find any point where they could be ascended. If anything, they were more impossible than at the first point where we had met them. Their absolute steepness is indicated in the photograph which I took over the stony desert.

"Surely," said I, as we discussed the situation, "the rain must find its way down somehow. There are bound to be water-channels in the rocks."

"Our young friend has glimpses of lucidity," said Professor Challenger, patting me upon the shoulder.

"The rain must go somewhere," I repeated.

"He keeps a firm grip upon actuality. The only drawback is that we have conclusively proved by ocular demonstration that there are no water channels down the rocks."

"Where, then, does it go?" I persisted.

"I think it may be fairly assumed that if it does not come outwards it must run inwards."

"Then there is a lake in the centre."

"So I should suppose."

"It is more than likely that the lake may be an old crater," said Summerlee. "The whole formation is, of course, highly volcanic. But, however that may be, I should expect to find the surface of the plateau slope inwards with a considerable sheet of water in the centre, which may drain off, by some subterranean channel, into the marshes of the Jaracaca Swamp.

"Or evaporation might preserve an equilibrium," remarked Challenger, and the two learned men wandered off into one of their usual scientific arguments, which were as comprehensible as Chinese to the layman.

On the sixth day we completed our first circuit of the cliffs, and found ourselves back at the first camp, beside the isolated pinnacle of rock. We were a disconsolate party, for nothing could have been more minute than our investigation, and it was absolutely certain that there was no single point where the most active human being could possibly hope to scale the cliff. The place which Maple White's chalk-marks had indicated as his own means of access was now entirely impassable.

What were we to do now? Our stores of provisions, supplemented by our guns, were holding out well, but the day must come when they would need replenishment. In a couple of months the rains might be expected, and we should be washed out of our camp. The rock was harder than marble, and any attempt at cutting a path for so great a height was more than our time or resources would admit. No wonder that we looked gloomily at each other that night, and sought our blankets with hardly a word exchanged. I remember that as I dropped off to sleep my last recollection was that Challenger was squatting, like a monstrous bull-frog, by the fire, his huge head in his hands, sunk apparently in the deepest thought, and entirely oblivious to the good-night which I wished him.

But it was a very different Challenger who greeted us in the morning--a Challenger with contentment and self-congratulation shining from his whole person. He faced us as we assembled for breakfast with a deprecating false modesty in his eyes, as who should say, "I know that I deserve all that you can say, but I pray you to spare my blushes by not saying it." His beard bristled exultantly, his chest was thrown out, and his hand was thrust into the front of his jacket. So, in his fancy, may he see himself sometimes, gracing the vacant pedestal in Trafalgar Square, and adding one more to the horrors of the London streets.

"Eureka!" he cried, his teeth shining through his beard. "Gentlemen, you may congratulate me and we may congratulate each other. The problem is solved."

"You have found a way up?"

"I venture to think so."

"And where?"

For answer he pointed to the spire-like pinnacle upon our right.

Our faces—or mine, at least—fell as we surveyed it. That it could be climbed we had our companion's assurance. But a horrible abyss lay between it and the plateau.

"We can never get across," I gasped.

"We can at least all reach the summit," said he. "When we are up I may be able to show you that the resources of an inventive mind are not yet exhausted."

After breakfast we unpacked the bundle in which our leader had brought his climbing accessories. From it he took a coil of the strongest and lightest rope, a hundred and fifty feet in length, with climbing irons, clamps, and other devices. Lord John was an experienced mountaineer, and Summerlee had done some rough climbing at various times, so that I was really the novice at rock-work of the party; but my strength and activity may have made up for my want of experience.

It was not in reality a very stiff task, though there were moments which made my hair bristle upon my head. The first half was perfectly easy, but from there upwards it became continually steeper until, for the last fifty feet, we were literally clinging with our fingers and toes to tiny ledges and crevices in the rock. I could not have accomplished it, nor could Summerlee, if Challenger had not gained the summit (it was extraordinary to see such activity in so unwieldy a creature) and there fixed the rope round the trunk of the considerable tree which grew there. With this as our support, we were soon able to scramble up the jagged wall until we found ourselves upon the small grassy platform, some twenty-five feet each way, which formed the summit.

The first impression which I received when I had recovered my breath was of the extraordinary view over the country which we had traversed. The whole Brazilian plain seemed to lie beneath us, extending away and away until it ended in dim blue mists upon the farthest sky-line. In the foreground was the long slope, strewn with rocks and dotted with tree-ferns; farther off in the middle distance, looking over the saddle-back hill, I could just see the yellow and green mass of bamboos through which we had passed; and then, gradually, the vegetation increased until it formed the huge forest which extended as far as the eyes could reach, and for a good two thousand miles beyond.

I was still drinking in this wonderful panorama when the heavy hand of the Professor fell upon my shoulder.

"This way, my young friend," said he; "vestigia nulla retrorsum. Never look rearwards, but always to our glorious goal."

The level of the plateau, when I turned, was exactly that on which we stood, and the green bank of bushes, with occasional trees, was so near that it was difficult to realize how inaccessible it remained. At a rough guess the gulf was forty feet across, but, so far as I could see, it might as well have been forty miles. I placed one arm round the trunk of the tree and leaned over the abyss. Far down were the small dark figures of our servants, looking up at us. The wall was absolutely precipitous, as was that which faced me.

"This is indeed curious," said the creaking voice of Professor Summerlee.

I turned, and found that he was examining with great interest the tree to which I clung. That smooth bark and those small, ribbed leaves seemed familiar to my eyes. "Why," I cried, "it's a beech!"

"Exactly," said Summerlee. "A fellow-countryman in a far land."

"Not only a fellow-countryman, my good sir," said Challenger, "but also, if I may be allowed to enlarge your simile, an ally of the first value. This beech tree will be our saviour."

"By George!" cried Lord John, "a bridge!"

"Exactly, my friends, a bridge! It is not for nothing that I expended an hour last night in focusing my mind upon the situation. I have some recollection of once remarking to our young friend here that G. E. C. is at his best when his back is to the wall. Last night you will admit that all our backs were to the wall. But where will-power and intellect go together, there is always a way out. A drawbridge had to be found which could be dropped across the abyss. Behold it!"

It was certainly a brilliant idea. The tree was a good sixty feet in height, and if it only fell the right way it would easily cross the chasm. Challenger had slung the camp axe over his shoulder when he ascended. Now he handed it to me.

"Our young friend has the thews and sinews," said he. "I think he will be the most useful at this task. I must beg, however, that you will kindly refrain from thinking for yourself, and that you will do exactly what you are told."

Under his direction I cut such gashes in the sides of the trees as would ensure that it should fall as we desired. It had already a strong, natural tilt in the direction of the plateau, so that the matter was not difficult. Finally I set to work in earnest upon the trunk, taking turn and turn with Lord John. In a little over an hour there was a loud crack, the tree swayed forward, and then crashed over, burying its branches among the bushes on the farther side. The severed trunk rolled to the very edge of our platform, and for one terrible second we all thought it was over. It balanced itself, however, a few inches from the edge, and there was our bridge to the unknown.

All of us, without a word, shook hands with Professor Challenger, who raised his straw hat and bowed deeply to each in turn.

"I claim the honour," said he, "to be the first to cross to the unknown land—a fitting subject, no doubt, for some future historical painting."

He had approached the bridge when Lord John laid his hand upon his coat.

"My dear chap," said he, "I really cannot allow it."

"Cannot allow it, sir!" The head went back and the beard forward.

"When it is a matter of science, don't you know, I follow your lead because you are by way of bein' a man of science. But it's up to you to follow me when you come into my department."

"Your department, sir?"

"We all have our professions, and soldierin' is mine. We are, accordin' to my ideas, invadin' a new country, which may or may not be chock-full of enemies of sorts. To barge blindly into it for want of a little common sense and patience isn't my notion of management."

The remonstrance was too reasonable to be disregarded. Challenger tossed his head and shrugged his heavy shoulders.

"Well, sir, what do you propose?"

"For all I know there may be a tribe of cannibals waitin' for lunch-time among those very bushes," said Lord John, looking across the bridge. "It's better to learn wisdom before you get into a cookin'-pot; so we will content ourselves with hopin' that there is no trouble waitin' for us, and at the same time we will act as if there were. Malone and I will go down again, therefore, and we will fetch up the four rifles, together with Gomez and the other. One man can then go across and the rest will cover him with guns, until he sees that it is safe for the whole crowd to come along."

Challenger sat down upon the cut stump and groaned his impatience; but Summerlee and I were of one mind that Lord John was our leader when such practical details were in question. The climb was a more simple thing now that the rope dangled down the face of the worst part of the ascent. Within an hour we had brought up the rifles and a shot-gun. The half-breeds had ascended also, and under Lord John's orders they had carried up a bale of provisions in case our first exploration should be a long one. We had each bandoliers of cartridges.

"Now, Challenger, if you really insist upon being the first man in," said Lord John, when every preparation was complete.

"I am much indebted to you for your gracious permission," said the angry Professor; for never was a man so intolerant of every form of authority. "Since you are good enough to allow it, I shall most certainly take it upon myself to act as pioneer upon this occasion."

Seating himself with a leg overhanging the abyss on each side, and his hatchet slung upon his back, Challenger hopped his way across the trunk and was soon at the other side. He clambered up and waved his arms in the air.

"At last!" he cried; "at last!"

I gazed anxiously at him, with a vague expectation that some terrible fate would dart at him from the curtain of green behind him. But all was quiet, save that a strange, many-coloured bird flew up from under his feet and vanished among the trees.

Summerlee was the second. His wiry energy is wonderful in so frail a frame. He insisted upon having two rifles slung upon his back, so that both Professors were armed when he had made his transit. I came next, and tried hard not to look down into the horrible gulf over which I was passing. Summerlee held out the butt-end of his rifle, and an instant later I was able to grasp his hand. As to Lord John, he walked across—actually walked without support! He must have nerves of iron.

And there we were, the four of us, upon the dreamland, the lost world, of Maple White. To all of us it seemed the moment of our supreme triumph. Who could have guessed that it was the prelude to our supreme disaster? Let me say in a few words how the crushing blow fell upon us.

We had turned away from the edge, and had penetrated about fifty yards of close brushwood, when there came a frightful rending crash from behind us. With one impulse we rushed back the way that we had come. The bridge was gone!

Far down at the base of the cliff I saw, as I looked over, a tangled mass of branches and splintered trunk. It was our beech tree. Had the edge of the platform crumbled and let it through? For a moment this explanation was in all our minds. The next, from the farther side of the rocky pinnacle before us a swarthy face, the face of Gomez the half-breed, was slowly protruded. Yes, it was Gomez, but no longer the Gomez of the demure smile and the mask-like expression. Here was a face with flashing eyes and distorted features, a face convulsed with hatred and with the mad joy of gratified revenge.

"Lord Roxton!" he shouted. "Lord John Roxton!"

"Well," said our companion, "here I am."

A shriek of laughter came across the abyss.

"Yes, there you are, you English dog, and there you will remain! I have waited and waited, and now has come my chance. You found it hard to get up; you will find it harder to get down. You cursed fools, you are trapped, every one of you!"

We were too astounded to speak. We could only stand there staring in amazement. A great broken bough upon the grass showed whence he had gained his leverage to tilt over our bridge. The face had vanished, but presently it was up again, more frantic than before.

"We nearly killed you with a stone at the cave," he cried; "but this is better. It is slower and more terrible. Your bones will whiten up there, and none will know where you lie or come to cover them. As you lie dying, think of Lopez, whom you shot five years ago on the Putomayo River. I am his brother, and, come what will I will die happy now, for his memory has been avenged." A furious hand was shaken at us, and then all was quiet.

Had the half-breed simply wrought his vengeance and then escaped, all might have been well with him. It was that foolish, irresistible Latin impulse to be dramatic which brought his own downfall. Roxton, the man who had earned himself the name of the Flail of the Lord through three countries, was not one who could be safely taunted. The half-breed was descending on the farther side of the pinnacle; but before he could reach the ground Lord John had run along the edge of the plateau and gained a point from which he could see his man. There was a single crack of his rifle, and, though we saw nothing, we heard the scream and then the distant thud of the falling body. Roxton came back to us with a face of granite.

"I have been a blind simpleton," said he, bitterly, "It's my folly that has brought you all into this trouble. I should have remembered that these people have long memories for blood-feuds, and have been more upon my guard."

"What about the other one? It took two of them to lever that tree over the edge."

"I could have shot him, but I let him go. He may have had no part in it. Perhaps it would have been better if I had killed him, for he must, as you say, have lent a hand."

Now that we had the clue to his action, each of us could cast back and remember some sinister act upon the part of the half-breed—his constant desire to know our plans, his arrest outside our tent when he was over-hearing them, the furtive looks of hatred which from time to time one or other of us had surprised. We were still discussing it, endeavoring to adjust our minds to these new conditions, when a singular scene in the plain below arrested our attention.

A man in white clothes, who could only be the surviving half-breed, was running as one does run when Death is the pacemaker. Behind him, only a few yards in his rear, bounded the huge ebony figure of Zambo, our devoted negro. Even as we looked, he sprang upon the back of the fugitive and flung his arms round his neck. They rolled on the ground together. An instant afterwards Zambo rose, looked at the prostrate man, and then, waving his hand joyously to us, came running in our direction. The white figure lay motionless in the middle of the great plain.

Our two traitors had been destroyed, but the mischief that they had done lived after them. By no possible means could we get back to the pinnacle. We had been natives of the world; now we were natives of the plateau. The two things were separate and apart. There was the plain which led to the canoes. Yonder, beyond the violet, hazy horizon, was the stream which led back to civilization. But the link between was missing. No human ingenuity could suggest a means of bridging the chasm which yawned between ourselves and our past lives. One instant had altered the whole conditions of our existence.

It was at such a moment that I learned the stuff of which my three comrades were composed. They were grave, it is true, and thoughtful, but of an invincible serenity. For the moment we could only sit among the bushes in patience and wait the coming of Zambo. Presently his honest black face topped the rocks and his Herculean figure emerged upon the top of the pinnacle.

"What I do now?" he cried. "You tell me and I do it."

It was a question which it was easier to ask than to answer. One thing only was clear. He was our one trusty link with the outside world. On no account must he leave us.

"No no!" he cried. "I not leave you. Whatever come, you always find me here. But no able to keep Indians. Already they say too much, Curupuri live on this place, and they go home. Now you leave them me no able to keep them."

It was a fact that our Indians had shown in many ways of late that they were weary of their journey and anxious to return. We realized that Zambo spoke the truth, and that it would be impossible for him to keep them.

"Make them wait till to-morrow, Zambo," I shouted; "then I can send letter back by them."

"Very good, sarr! I promise they wait till to-morrow, said the negro. "But what I do for you now?"

There was plenty for him to do, and admirably the faithful fellow did it. First of all, under our directions, he undid the rope from the tree-stump and threw one end of it across to us. It was not thicker than a clothes-line, but it was of great strength, and though we could not make a bridge of it, we might well find it invaluable if we had any climbing to do. He then fastened his end of the rope to the package of supplies which had been carried up, and we were able to drag it across. This gave us the means of life for at least a week, even if we found nothing else. Finally he descended and carried up two other packets of mixed goods—a box of ammunition and a number of other things, all of which we got across by throwing our rope to him and hauling it back. It was evening when he at last climbed down, with a final assurance that he would keep the Indians till next morning.

And so it is that I have spent nearly the whole of this our first night upon the plateau writing up our experiences by the light of a single candle-lantern.

We supped and camped at the very edge of the cliff, quenching our thirst with two bottles of Apollinaris which were in one of the cases. It is vital to us to find water, but I think even Lord John himself had had adventures enough for one day, and none of us felt inclined to make the first push into the unknown. We forbore to light a fire or to make any unnecessary sound.

To-morrow (or to-day, rather, for it is already dawn as I write) we shall make our first venture into this strange land. When I shall be able to write again—or if I ever shall write again—I know not. Meanwhile, I can see that the Indians are still in their place, and I am sure that the faithful Zambo will be here presently to get my letter. I only trust that it will come to hand.

P.S.—The more I think the more desperate does our position seem. I see no possible hope of our return. If there were a high tree near the edge of the plateau we might drop a return bridge across, but there is none within fifty yards. Our united strength could not carry a trunk which would serve our purpose. The rope, of course, is far too short that we could descend by it. No, our position is hopeless—hopeless!
