Thursday's Serials: "Dwellers in the Mirage" by A. E. Merritt (in English) - III

CHAPTER V: THE MIRAGE

                Jim had sat silent, watching me, but now and again I had seen the Indian stoicism drop from his face. He leaned over and put a hand on my shoulder.

                "Leif," he said quietly, "how could I have known? For the first time, I saw you afraid - it hurt me. I did not know...”

                From Tsantawu, the Cherokee, this was much. "It's all right, Indian. Snap back," I said roughly. He sat for a while not speaking, throwing little twigs on the fire.

                "What did you friend Barr say about it?" he asked abruptly.

                "He gave me hell," I said. "He gave me hell with the tears streaming down his cheeks. He said that never had anyone betrayed science as I had since Judas kissed Christ. He was keen on mixed metaphors that got under your skin. That went deep under mine, for it was precisely what I was thinking of myself - not as to science but as to the girl. I had given her the kiss of Judas all right. Barr said that I had been handed the finest opportunity man ever had given him. I could have solved the whole mystery of the Gobi and its lost civilization. I had run away like a child from a bugaboo. I was not only atavistic in body, I was atavistic in brain. I was a blond savage cowering before my mumbo-jumbos. He said that if he had been given my chance he would have let himself be crucified to have learned the truth. He would have, too. He was not lying."

                "Admirably scientific," said Jim. "But what did he say about what you saw?"

                "That is was nothing but hypnotic suggestion by the old priest. I had seen what he had willed me to see - just as before, under his will, I had seen myself riding to the temple. The girl hadn't dissolved. She had probably been standing in the wings laughing at me. But if everything that my ignorant mind had accepted as true had been true then my conduct was even more unforgivable. I should have remained, studied the phenomena and brought back the results for science to examine. What I had told him of the ritual of Khalk'ru was nothing but the second law of thermo-dynamics expressed in terms of anthropomorphism. Life was an intrusion upon Chaos, using that word to describe the unformed, primal state of the universe. An invasion. An accident. In time all energy would be changed to static heat, impotent to give birth to any life whatsoever. The dead universes would float lifelessly in the illimitable void. The void was eternal, life was not. Therefore the void would absorb it. Suns, worlds, gods, men, an things animate, would return to the void. Go back to Chaos. Back to Nothingness. Back to Khalk'ru. Or if my atavistic brain preferred the term - back to the Kraken. He was bitter."

                "But the others saw the girl taken, you say. How did he explain that?"

                "Oh, easily. That was mass hypnotism - like the Angels of Mons, the ghostly bowmen of Crecy and other collective hallucinations of the War. I had been a catalyzer. My likeness to the traditional ancient race, my completeness as a throwback, my mastery at Khalk'ru's ritual, the faith the Uighurs had in me - all this had been the necessary element in bringing about the collective hallucination of the tentacle. Obviously the priests had long been trying to make work a drug in which an essential chemical was lacking. I, for some reason, was the missing chemical – the catalyzer. That was all." Again he sat thinking, breaking the little twigs.

                "It's a reasonable explanation. But you weren't convinced?"

                "No, I wasn't convinced - I saw the girl's face when the tentacle touched her." He arose, stood staring toward the north.

                "Leif," he asked suddenly, "what did you do with the ring?"

                I drew out the little buckskin pouch, opened it and handed the ring to him. He examined it closely, returned it to me.

                "Why did you keep it, Leif?"

                "I don't know." I slipped the ring over my thumb. "I didn't give it back to the old priest; he didn't ask for it. Oh, hell - I'll tell you why I kept it - for the same reason Coleridge's Ancient Mariner had the albatross tied round his neck. So I couldn't forget I'm a murderer."

                I put the ring back in the buckskin bag, and dropped it down my neck. Faintly from the north came a roll of drums. It did not seem to travel with the wind this time. It seemed to travel underground, and died out deep beneath us.

                "Khalk'ru!" I said.

                "Well, don't let's keep the old gentleman waiting," said Jim cheerfully.

                He busied himself with the packs, whistling. Suddenly he turned to me.

                "Listen, Leif. Barr's theories sound good to me. I'm not saying that if I'd been in your place I would have accepted them. Maybe you're right. But I'm with Barr - until events, if-when-and-how they occur, prove him wrong."

                "Fine!" I said heartily, and entirely without sarcasm.

                "May your optimism endure until we get back to New York - if-when-and-how."

                We shouldered the packs, and took up our rifles and started northward.

                It was not hard going, but it was an almost constant climb. The country sloped upward, sometimes at a breathtaking pitch. The forest, unusually thick and high for the latitude, began to thin. It grew steadily cooler. After we had covered about fifteen miles we entered a region of sparse and stunted trees. Five miles ahead was a thousand-feet-high range of bare rocks. Beyond this range was a jumble of mountains four to five thousand feet higher, treeless, their peaks covered with snow and ice, and cut by numerous ravines which stood out glistening white like miniature glaciers. Between us and the nearer range stretched a plain, all grown over with dwarfed thickets of wild roses, blueberries and squawbemes, and dressed in the brilliant reds and blues and greens of the brief Alaskan summer.

                "If we camp at the base of those hills, we'll be out of that wind," said Jim. "It's five o'clock. We ought to make it in an hour."

                We set off. Bursts of willow ptarmigans shot up around us from the berry thickets like brown rockets; golden plovers and curlews were whistling on all sides; within rifle shot a small herd of caribou was feeding, and the little brown cranes were stalking everywhere. No one could starve in that country, and after we had set up camp we dined very well.

                There were no sounds that night - or if there were we slept too deeply to hear them.

                The next morning we debated our trail. The low range stood directly in our path north. It continued, increasing in height, both east and west. It presented no great difficulties from where we were, at least so far as we could see. We determined to climb it, taking it leisurely. It was more difficult than it had appeared; it took us two hours to wind our way to the top.

                We tramped across the top toward a line of huge boulders that stretched like a wall before us. We squeezed between two of these, and drew hastily back. We were standing at the edge of a precipice that dropped hundreds of feet sheer to the floor of a singular valley. The jumble of snow-and-ice-mantled mountains clustered around it. At its far end, perhaps twenty miles away, was a pyramidal-shaped peak.

                Down its centre, from tip to the floor of the valley, ran a glittering white streak, without question a glacier filling a chasm which split the mountain as evenly as though it had been made by a single sword stroke. The valley was not wide, not more than five miles, I estimated, at its widest point. A long and narrow valley, its far end stoppered by the glacier-cleft giant, its sides the walls of the other mountains, dropping, except here and there where there had been falls of rock, as precipitously into it as the cliff under us.

                But it was the floor of the valley itself that riveted our attention. It seemed nothing but a tremendous level field covered with rocky rubble. At the far end, the glacier ran through this rubble for half the length of the valley. There was no trace of vegetation among the littered rocks. There was no hint of green upon the surrounding mountains; only the bare black cliffs with their ice and snow-filled gashes. It was a valley of desolation.

                "It's cold here, Leif." Jim shivered.

                It was cold - a cold of a curious quality, a still and breathless cold.  It seemed to press out upon us from the valley, as though to force us away.

                "It's going to be a job getting down there," I said.

                "And hard going when we do," said Jim. "Where the hell did all those rocks come from, and what spread them out so flat?"

                "Probably dropped by that glacier when it shrunk," I said. "It looks like a terminal moraine. In fact this whole place looks as though it had been scooped out by the ice."

                "Hold on to my feet, Leif, I'll take a look." He lay on his belly and wriggled his body over the edge. In a minute or two I heard him call, and pulled him back.

                "There's a slide about a quarter of a mile over there to the left," he said. "I couldn't tell whether it goes all the way to the top. We'll go see. Leif, how far down do you think that valley is?"

                "Oh, a few hundred feet."

                "It's all of a thousand if it's an inch. The cliff goes down and down. I don't understand what makes the bottom seem so much closer here. It's a queer place, this."

                We picked up the packs and marched off behind the wall - like rim of boulders. In a little while we came across a big gouge in the top, running far back. Here frost and ice had bitten out the rock along some fault. The shattered debris ran down the middle of the gouge like giant stepping-stones clear to the floor of the valley.

                "We'll have to take the packs off to negotiate that," said Jim. "What shall be do - leave them here while we explore, or drop them along with us as we go?"

                "Take them with us. There must be an outlet off there at the base of the big mountain."

                We began the descent. I was scrambling over one of the rocks about a third of the way when I heard his sharp exclamation.

                Gone was the glacier that had thrust its white tongue in among the rubble. Gone was the rubble. Toward its far end, the valley's floor was covered with scores of pyramidal black stones, each marked down its centre with a streak of glistening white. They stood in ranks, spaced regularly, like the dolmens of the Druids. They marched half-down the valley. Here and there between them arose wisps of white steam, like smokes of sacrifices.

                Between them and us, lapping at the black cliffs, was a blue and rippling lake! It filled the lower valley from side to side. It rippled over the edges of the shattered rocks still far below us.

                Then something about the marshalled ranks of black stones struck me.

                "Jim! Those pyramid-shaped rocks. Each and every one of them is a tiny duplicate of the mountain behind them! Even to the white streak!"

                As I spoke, the blue lake quivered. It flowed among the black pyramids, half-submerging them, quenching the sacrificial smokes. It covered the pyramids. Again it quivered. It was gone. Where the lake had been was once more the rubble-covered floor of the valley.

                There had been an odd touch of legerdemain about the transformations, like the swift work of a master magician. And it had been magic - of a kind. But I had watched nature perform that magic before.

                "Hell!" I said. "It's a mirage!"

                Jim did not answer. He was staring at the valley with a singular expression.

                "What's the matter with you, Tsantawu? Listening to the ancestors again? It's only a mirage."

                "Yes?" he said. "But which one? The lake - or the rocks?"

                I studied the valley's floor. It looked real enough. The theory of a glacial moraine accounted for its oddly level appearance - that and our height above it. When we reached it we would find that distribution of boulders uncomfortably uneven enough, I would swear.

                "Why, the lake of course."          

"No," he said, "I think the stones are the mirage."

                "Nonsense. There's a layer of warm air down there. The stones radiate the sun's heat. This cold air presses on it. It's one of the conditions that produces mirages, and it has just done it for us. That's all."

                "No," he said, "it isn't all."

                He leaned against the rock.

                "Leif, the ancestors had a few things more to say last night than I told you."

                "I know damned well they did."

                "They spoke of Ataga'hi. Does that mean anything to you."

                "Not a thing."

                "It didn't to me - then. It does now. Ataga'hi was an enchanted lake, in the wildest part of the Great Smokies, westward from the headwaters of the Ocana-luftee. It was the medicine lake of the animals and birds. All the Cherokee knew it was there, though few had seen it. If a stray hunter came close, all he saw was a stony flat, without blade of grass, forbidding. But by prayer and fasting and an all-night vigil, he could sharpen his spiritual sight. He would then behold at daybreak a wide shallow sheet of purple water, fed by springs, spouting from the high cliffs around. And in the water all kinds of fish and reptiles, flocks of ducks and geese and other birds flying about, and around the lake the tracks of animals. They came to Ataga'hi to be cured of wounds or sickness. The Great Spirit had placed an island in the middle of the lake. The wounded, the sick animals and birds swam to it. When they had reached it - the waters of Ataga'hi had cured them. They came up on its shores - whole once more. Over Ataga'hi ruled the peace of God. All creatures were friends."

                "Listen, Indian, are you trying to tell me this is your medicine lake?"

                "I didn't say that at all. I said the name of Ataga'hi kept coming into my mind. It was a place that appeared to be a stony flat, without blade of grass, forbidding. So does this place. But under that illusion was – a lake. We saw a lake. It's a queer coincidence, that's all. Perhaps the stony flat of Ataga'hi was a mirage -” He hesitated: "Well, if some other things the ancestors mentioned turn up, I'll shift sides and take your version of that Gobi affair."

                "That lake was the mirage. I'm telling you."

                He shook his head, stubbornly.

                "Maybe. But maybe what we see down there now is mirage, too. Maybe both are mirage. And if so, then, how deep is the real floor, and can we make our way over it?"

                He stood staring silently at the valley. He shivered, and again I was aware of the curiously intense quality of the cold. I stooped and caught hold of my pack. My hands were numb.

                "Well, whatever it is - let's find out."

                A quiver ran through the valley floor. Abruptly it became again the shimmering blue lake. And as abruptly turned again to nibbled rock.

                But not before I had seemed to see within that lake of illusion – if illusion it were - a gigantic shadowy shape, huge black tentacles stretching out from a vast and nebulous body... a body which seemed to vanish back into immeasurable distances... vanishing into the void... as the Kraken of the Gobi cavern had seemed to vanish into the void... into that void which was - Khalk'ru!

                We crept between, scrambled over and slid down the huge broken fragments. The further down we went, the more intense became the cold. It had a still and creeping quality that seeped into the marrow. Sometimes we dropped the packs ahead of us, sometimes dragged them after us. And ever more savagely the cold bit into our bones.

                By the frequent glimpses of the valley floor, I was more and more assured of its reality. Every mirage I had ever beheld - and in Mongolia I had seen many - had retreated, changed form, or vanished as I drew near. The valley floor did none of these things. It was true that the stones seemed to be squatter as we came closer; but I attributed that to the different angle of vision.

                We were about a hundred feet above the end of the slide when I began to be less sure. The travelling had become peculiarly difficult. The slide had narrowed. At our left the rock was clean swept, stretching down to the valley as smoothly as though it had been brushed by some titantic broom. Probably an immense fragment had broken loose at this point, shattering into the boulders that lay heaped at its termination. We veered to the right, where there was a ridge of rocks, pushed to the side by that same besom of stone. Down this ridge we picked our way.

                Because of my greater strength, I was carrying both our rifles, swung by a thong over my left shoulder. Also I was handling the heavier pack. We came upon an extremely awkward place. The stone upon which I was standing suddenly tipped beneath my weight. It threw me sideways. The pack slipped from my hands, toppled, and fell over on the smooth rock. Automatically I threw myself forward, catching at it. The thong holding the two rifles broke. They went slithering after the escaping pack.

It was one of those combinations of circumstances that makes one believe in a God of Mischance. The thing might have happened anywhere else on our journey without any result whatever. And even at that moment I didn't think it mattered.

                "Well," I said, cheerfully, "that saves me carrying them. We can pick them up when we get to the bottom."

                "That is," said Jim, "if there is a bottom."

                I cocked my eye down the slide. The rifles had caught up with the pack

and the three were now moving fast.

                "There they stop," I said. They were almost on the rubble at the end.

                "The hell they do," said Jim. "There they go!"

                I rubbed my eyes, and looked and looked again. The pack and the pushing rifles should have been checked by that barrier at the slide's end. But they had not been. They had vanished.

CHAPTER VI: THE SHADOWED-LAND

There had been a queer quivering when rifles and pack had touched the upthrust of rock. Then they had seemed to melt into it.

                "I'd say they dropped into the lake," said Jim.

                "There's no lake. They dropped into some break in the rock. Come on -”

                He gripped my shoulder.

                "Wait, Leif. Go slow."

                I followed his pointing finger. The barrier of stones had vanished. Where they had been, the slide ran, a smooth tongue of stone, far out into the valley.

                "Come on," I said.

                We went down, testing every step. With each halt, the nibbled plain became flatter and flatter, the boulders squatted lower and lower. A cloud drifted over the sun. There were no boulders. The valley floor stretched below us, a level slate-grey waste!

                The slide ended abruptly at the edge of this waste. The rocks ended as abruptly, about fifty feet ahead. They stood at the edge with the queer effect of stones set in place when the edge had been viscous. Nor did the waste appear solid; it, too, gave the impression of viscosity; through it ran a slight but constant tremor, like waves of heat over a sun-baked road - yet with every step downward the bitter, still cold increased until it was scarcely to be borne.

                There was a narrow passage between the shattered rocks and the cliff at our right. We crept through it. We stood upon an immense flat stone at the very edge of the strange plain. It was neither water nor rock; more than anything, it had the appearance of a thin opaque liquid glass, or a gas that had been turned semi-liquid.

                I stretched myself out on the slab, and reached out to touch it. I did touch it - there was no resistance; I felt nothing. I let my hand sink slowly in. I saw my hand for a moment as though reflected in a distorting mirror, and then I could not see it at all. But it was pleasantly warm down there where my hand had disappeared. The chilled blood began to tingle in my numbed fingers. I leaned far over the stone and plunged both arms in almost to the shoulders. It felt damned good.

                Jim dropped beside me and thrust in his arms.

                "It's air," he said.

                "Feels like it -” I began, and then a sudden realization came to me -”the rifles and the pack! If we don't get them we're out of luck!"

                He said: "If Khalk'ru is - guns aren't going to get us away from him."

                "You think this -” I stopped, memory of the shadowy shape in the lake of illusion coming back to me.

                "Usunhi'yi, the Darkening-land. The Shadowed-land your old priest called it, didn't he? I'd say this fits either description."

                I lay quiet; no matter what the certainty of a coming ordeal a man may carry in his soul, he can't help a certain shrinking when he knows his foot is at the threshold of it. And now quite clearly and certainly I knew just that. All the long trail between Khalk'ru's Gobi temple and this place of mirage was wiped out. I was stepping from that focus of Khalk'ru's power into this one - where what had been begun in the Gobi must be ended. The old haunting horror began to creep over me. I fought it.

                I would take up the challenge. Nothing on earth could stop me now from going on. And with that determination, I felt the horror sullenly retreat, leave me. For the first time in years I was wholly free of it.

                "I'm going to see what's down there." Jim drew up his arms. "Hold on to my feet, Leif, and I'll slip over the edge of the stone. I felt along its edge and it seems to go on a bit further."

                "I'll go first." I said. "After all, it's my party."

                "And a fine chance I'd have to pull you up if you fell over, you human elephant. Here goes - catch hold."

                I had just time to grip his ankles as he wriggled over the stone, and his head and shoulders passed from sight. On he went, slowly writhing along the slanting rock until my hands and arms were hidden to the shoulders. He paused - and then from the mysterious opacity in which he had vanished came a roar of crazy laughter.

                I felt him twist and try to jerk his feet away from me. I pulled him, fighting against me every inch of the way, out upon the stone. He came out roaring that same mad laughter. His face was red, and his eyes were shining drunkenly; he had in fact all the symptoms of a laughing drunk. But the rapidity of his respiration told me what had happened.

                "Breathe slowly," I shouted in his ear. "Breathe slowly, I tell you."

                And then, as his laughter continued and his struggles to tear loose did not abate, I held him down with one arm and closed his nose and mouth with my hand. In a moment or two he relaxed. I released him; and he sat up groggily.

                "Funniest things," he said, thickly. "Saw funniest faces...”

                He shook his head, took a deep breath or two, and lay back on the stone.

                "What the hell happened to me, Leif?"

                "You had an oxygen burn, Indian," I said. "A nice cheap jag on air loaded with carbon-dioxide. And that explains a lot of things about this place. You came up breathing three to the second, which is what carbon-dioxide does to you. Works on the respiratory centres of the brain and speeds up respiration. You took in more oxygen than you could use, and you got drunk on it. What did you see before the world became so funny?"

                "I saw you," he said. "And the sky. It was like looking up out of water. I looked down and around. A little below me was something like a floor of pale green mist. I couldn't see through it. It's warm in there, good and plenty warm, and it smells like trees and flowers. That's all I managed to grasp before I went goofy. Oh, yes, this rock fall keeps right on going down. Maybe we can get to the bottom of it – if we don't laugh ourselves off. I'm going right out and sit in that mirage up to my neck - my God, Leif, I'm freezing!"

                I looked at him with concern. His lips were blue, his teeth chattering. The transition from the warmth to the bitter cold was having its effect, and a dangerous one.

                "All right," I said, rising. "I'll go first. Breathe slowly, take deep, long breaths as slowly as you can, and breathe out just as slowly. You'll soon get used to it. Come on."

                I slung the remaining pack over my back, craw-fished over the side of the stone, felt solid rock under my feet, and drew myself down within the mirage.

                It was warm enough; almost as warm as the steam-room of a Turkish bath. I looked up and saw the sky above me like a circle of blue, misty at its edges. Then I saw Jim's legs dropping down toward me, his body bent back from them at an impossible angle. I was seeing him, in fact, about as a fish does an angler wading in its pool. His body seemed to telescope and he was squatting beside me.

                "God, but this feels good!"

                "Don't talk," I told him. "Just sit here and practise that slow breathing. Watch me."

                We sat there, silently, for all of half an hour. No sound broke the stillness around us. It smelled of the jungle, of fast-growing vigorous green life, and green life falling as swiftly into decay; and there were elusive, alien fragrances. All I could see was the circle of blue sky above, and perhaps a hundred feet below us the pale green mist of which Jim had spoken. It was like a level floor of cloud, impenetrable to the vision. The rock-fall entered it and was lost to sight. I felt no discomfort, but both of us were dripping with sweat. I watched with satisfaction Jim's deep, unhurried breathing.

                "Having any trouble?" I asked at last.

                "Not much. Now and then I have to put the pedal down. But I think I'm getting the trick."

                "All right," I said. "Soon we'll be moving. I don't believe it will get any worse as we go down."

                "You talk like an old-timer. What's your idea of this place anyway, Leif?"

                "Simple enough. Although the combination hasn't a chance in millions to be duplicated. Here is a wide, deep valley entirely hemmed in by precipitous cliffs. It is, in effect, a pit. The mountains enclosing it are seamed with glaciers and ice streams and there is a constant flow of cold air into this pit, even in summer. There is probably volcanic activity close beneath the valley's floor, boiling springs and the like. It may be a miniature of the Valley of Ten Thousand Smokes over to the west. All this produces an excess of carbon-dioxide. There is most probably a lush vegetation which adds to the product. What we are going into is likely to be a little left-over fragment of the Carboniferous Age - about ten million years out of its time. The warm, heavy air fills the pit until it reaches the layer of cold air we've just come from. The mirage is produced where the two meet, by approximately the same causes which produce every mirage. How long it's been this way, God alone knows. Parts of Alaska never had a Glacial Age - the ice for some reason or another didn't cover them. When what is New York was under a thousand feet of ice, the Yukon Flats were an oasis filled with all sorts of animal and plant life. If this valley existed then, we're due to see some strange survivals. If it's comparatively recent, we'll probably run across some equally interesting adaptations. That's about all, except there must be an outlet of some kind somewhere at about this level, otherwise the warm air would fill the whole valley to the top, as gas does a tank.Let's be going."

                "I begin to hope we find the guns," said Jim, thoughtfully.

                "As you pointed out, they'd be no good against Khalk'ru - what, who, if and where he is," I said. "But they'd be handy against his attendant devils. Keep an eye out for them - I mean the guns."

                We started down the rock-fall, toward the floor of green mist. The going was not very difficult. We reached the mist without having seen anything of rifles or packs. The mist looked like a heavy fog. We entered it, and that was precisely what it was. It closed around us, thick and warm. The rocks were reeking wet and slippery, and we had to feel for every foot of the way. Twice I thought our numbers were up. How deep that mist was, I could not tell, perhaps two or three hundred feet - a condensation brought about by the peculiar atmospheric conditions that produced the mirage.

                The mist began to lighten. It maintained its curious green tint, but I had the idea that this was due to reflection from below. Suddenly it thinned to nothing. We came out of it upon a breast where the falling rocks had met some obstruction and had piled up into a barrier about thrice my height. We climbed that barrier.

                We looked upon the valley beneath the mirage.

                It lay a full thousand feet beneath us. It was filled with pale green light like that in a deep forest glade. That light was both lucent and vaporous, lucent where we stood, but hiding the distance with misty curtains of pallid emerald. To the north and on each side as far as I could see, and melting into the vaporous emerald curtains, was a vast carpet of trees. Their breath came pulsing up to me, jungle-strong, laden with the unfamiliar fragrances. At left and right, the black cliffs fell sheer to the forest edge.

                "Listen!" Jim caught my arm.

                At first only a faint tapping, then louder and louder, we heard from far away the beating of drums, scores of drums, in a strange staccato rhythm - shrill, mocking, jeering! But they were no drums of Khalk'ru! In them was nothing of that dreadful trampling of racing feet upon a hollow world.

                They ceased. As though in answer, and from an entirely different direction, there was a fanfarade of trumpets, menacing, warlike. If brazen notes could curse, these did. Again the drums broke forth, still mocking, taunting, defiant.

                "Little drums," Jim was whispering. "Drums of -” He dropped down from the rocks, and I followed. The barrier led to the east, dipping steadily downward. We followed its base. It stood like a great wall between us and the valley, barring our vision. We heard the drums no more. We descended five hundred feet at least before the barrier ended. At its end was another rock slide like that down which the rifles and pack had fallen.

                We stood studying it. It descended at an angle of about forty-five degrees, and while not so smooth as the other, it had few enough foot-holds.

                The air had steadily grown warmer. It was not an uncomfortable heat; there was a queer tingling life about it, an exhalation of the crowding forest or of the valley itself, I thought. It gave me a feeling of rampant, reckless life, a heady exaltation. The pack had grown tiresome. If we were to negotiate the slide, and there seemed nothing else to do, I couldn't very well carry it. I unslung it.

                "Letter of introduction" I said, and sent it slithering down the rock.

                "Breathe deep and slow, you poor ass," said Jim, and laughed.

                His eyes were bright; he looked happy, like a man from whom some burden of fear and doubt has fallen. He looked, in fact, as I had felt when I had taken up that challenge of the unknown not so long before. And I wondered.

                The slithering pack gave a little leap, and dropped completely out of sight. Evidently the slide did not go all the way to the valley floor, or, if so, it continued at a sharper angle at the point of the pack's disappearance.

                I let myself over cautiously, and began to worm down the slide flat on my belly, Jim following. We had negotiated about three-quarters of it when I heard him shout. Then his falling body struck me. I caught him with one hand, but it broke my own precarious hold. We went rolling

down the slide and dropped into space. I felt a jarring shock, and abruptly went completely out.
