offered finger- and toeholds; the change in the falls course had been fairly recent, and it had not had time to wear all the ledge smooth. The greatest problem was with the line overhead. By the time he had descended twenty meters and had laced the line through eight carabiners, it took dangerous effort to tug slack against the heavy friction of the soaked rope through so many snap links; the effort of pulling on the line lifted his body partially out of his footholds. And this weakening of his stance occurred, of course, just when Le Cagot was paying out line from above and was, therefore, least able to hold him, should he slip.
He inched down through the sheath of mist until the oily black-and-silver sheet of the waterfall was only a foot from his helmet lamp, and there he paused and collected himself for the diciest moment of the descent.
First he would have to establish a cluster of pitons, so that he could work independently of Le Cagot, who might blindly resist on the line and arrest Hel while he was under the falls, blinded by the shaft of water, feeling for holds he could not see. And he would be taking the weight of the falling water on his back and shoulders. He had to give himself enough line to move all the way through the cascade, because he would not be able to breathe until he was behind it. On the other hand, the more line he gave himself, the greater his drop would be if the water knocked him off. He decided to give himself about three meters of slack. He would have liked more to avoid the possibility of coming to the end of his slack while still under the column of water, but his judgment told him that three meters was the maximum length that would swing him back out of the line of the falls, should he fall and knock himself out for long enough to drown, if he was hanging in the falls.
Hel edged to the face of the metallic, glittering sheet of water until it was only inches away from his face, and soon he began to have the vertigo sensation that the water was standing still, and his body rising through the roar and the mist. He reached into the face of the falls, which split in a heavy, throbbing bracelet around his wrist, and felt around for the deepest handhold he could find. His fingers wriggled their way into a sharp little crack, unseen behind the water. The hold was lower than he would have wished, because he knew the weight of the water on his back would force him down, and the best handhold would have been high, so the weight would have jammed his fingers in even tighter. But it was the only crack he could find, and his shoulder was beginning to tire from the pounding of the water on his outstretched arm. He took several deep breaths, fully exhaling each one because he knew that it is more the buildup of carbon dioxide in the lungs than the lack of oxygen that forces a man to gasp for air. The last breath he took deeply, stretching his diaphragm to its full. Then he let a third of it out, and he swung into the falls.
It was almost comic, and surely anticlimactic.
The sheet of falling water was less than twenty centimeters thick, and the same movement that swung him into it sent him through and behind the cascade, where he found himself on a good ledge below which was a book corner piled with rubble so easy that a healthy child could make the climb down.
It was so obvious a go that, there was no point in testing it, so Hel broke back through the sheet of water and scrambled up to Le Cagot's perch where, shouting over the din of the falls into Benat's ear, their helmets clicking together occasionally, he explained the happy situation. They decided to leave the line in place to facilitate the return, and down they went one after the other, until they were at the base of the rubble-packed book corner.
It was a peculiar phenomenon that, once they were behind the silver-black sheet of the falls, they could speak in almost normal volume, as the curtain of water seemed to block out sound, and it was quieter behind the falls than without. As they descended, the fails slowly broke up as a great quantity of its water spun off in the mist, and the weight of the cascade at the bottom was considerably less than it was above. Its mass was diffused, and passing through it was more like going through a torrential rainfall than a waterfall. They advanced cautiously through the blinding, frigid steam, over a slick rock floor scrubbed clean of rubble. As they pressed on, the mists thinned until they found themselves in the clear dark air, the noise of the falls receding behind them. They paused and looked around. It was beautiful, a diamond cave of more human dimensions than the awful Le Cagot's Chaos; a tourist cave, far beyond the access capacities of any tourist.
Although it was wasteful, their curiosity impelled them to scratch off another magnesium flare.
Breathtakingly beautiful. Behind them, billowing clouds of mist churning lazily in the suction of the falling water. All around and above them, wet and dripping, the walls were encrusted with aragonite crystals that glittered as Le Cagot moved the flare back and forth. Along the north wall, a frozen waterfall of flowstone oozed down the side and puddled like ossified taffy. To the east, receding and overlapping curtains of calcite drapery, delicate and razor-sharp, seemed to ripple in an unfelt spelean wind. Close to the walls, thickets of slender crystal stalactites pointed down toward stumpy stalagmites, and here and there the forest was dominated by a thick column formed by the union of these patient speleotherns.
They did not speak until the glare sputtered orange and went out, and the glitter of the walls was replaced by dancing dots of light in their eyes as they dilated to accommodate the relatively feeble helmet lamps. Le Cagot's voice was uncharacteristically hushed when he said, 'We shall call this Zazpiak Bat Cave.'
Hel nodded.
He squatted down and made a rough measurement back to the top of the waterfall with his clinometer, then he did a bit of mental arithmetic. 'We're down almost to the level of the Torrent of Holcarte. The outfall can't be far ahead.'
'Yes,' Le Cagot said, 'but where is the river? What have you done with it?'
It was true that the river had disappeared. Broken up by the falls, it had evidently sounded through cracks and fissures and must be running below them somewhere. There were two possibilities. Either it would emerge again within the cave somewhere before them, or the cracks around the base of the waterfall constituted its final swallow before its outfall into the gorge. This latter would be unfortunate, because it would deny them any hope of final conquest by swimming through to the open air and sky. It would also make the long vigil of the Basque lads camped at the outfall pointless.
Le Cagot took the lead as they advanced through Zazpiak Bat Cavern, as he always did when the going was reasonably easy. They both knew that Nicholai was the better rock tactician; it was not necessary for Le Cagot to admit it, or for Hel to accent it. The lead simply changed automatically with the nature of a cave's features. Hel led through shafts, down faces, around cornices; while Le Cagot led as they entered caves and dramatic features, which he therefore 'discovered' and named.
As he led, Le Cagot was testing his voice in the cave, singing one of those whining, atonic Basque songs that demonstrate the race's ability to withstand aesthetic pain. The song contained that uniquely Basque onomatopoeia that goes beyond imitations of sounds, to imitations of emotional states. In the refrain of Le Cagot's song, work was being done sloppily
He stopped singing when he approached the end of the diamond cave and stood before a broad, low-roofed gallery that opened out like a black, toothless grin. Indeed, it held a joke.
Le Cagot directed his lamp down the passage. The slope increased slightly, but it was no more than 15°, and there was enough overhead space for a man to stand erect. It was an avenue, a veritable boulevard! And yet more interesting, it was probably the last feature of the cave system. He stepped forward... and fell with a clatter of gear.
The floor of the passage was thickly coated with clay marl, as slick and filthy as axle grease and flat on his back, Le Cagot was slipping down the incline, not moving very fast at first, but absolutely helpless to arrest his slide. He cursed and pawed around for a hold, but everything was coated with the slimy mess, and there were no boulders or outcroppings to cling to. His struggling did no more than turn him around so that he was going down backward, half-sitting, helpless, furious, and risible. His slide began to pick up speed. From back on the edge of the marl shaft, Hel watched the helmet light grow smaller as it receded, turning slowly like the beam of a lighthouse. There was nothing he could do. The situation was basically comic, but if there was a cliff at the end of the passage...
There was no cliff at the end of the passage. Hel had never known a marl chute at this depth. At a good distance away, perhaps sixty meters, the light stopped moving. There was no sound, no call for help. Hel feared that Le Cagot had been bashed against the side of the passage and was lying there broken up.
