They angled sharply away from the shore. As the current took them, the walled city of Roniah fell away astern with amazing swiftness. It was not easy to estimate their speed, since they were a good two hundred meters from either shore; but Bryan guessed that the sediment-laden flood was racing along at a minimum of twenty knots. What would happen when this great volume of water was compressed between high rock walls farther downstream challenged the imagination of the anthropologist. His speculations were of a decidedly queasy sort.
Raimo, in the seat next to him, had found his own brand of solace. He took a pull from his replenished silver flask and offered it to Bryan rather half-heartedly. “Tanu popskull. Hardly Hudson’s Bay standard, but not too bad.”
“Maybe later,” Bryan said, smiling Raimo grunted and took another swallow. The euphoria of his morning adventure had faded away, leaving the ex-forester brooding and ill at ease. Bryan tried to draw Raimo out with questions about the previous night’s revelry but received only the curtest replies.
“You hadda be there,” Raimo said, and lapsed into silence.
For nearly an hour they moved easily through a wide bluff-sided channel, the forested foothills of the Alps on their left hand and arid tablelands rising above the near-jungle of the humid bottoms on the right. Occasionally, Creyn pointed out the location of a plantation; but the threes were so thick that it was impossible to see any details of the settlements ashore. They glimpsed smaller boats plying the shallows and once they overhauled a long covered barge riding deep in the water, bare-masted and having only a small bubble over the midships steersman’s cockpit. The bargee greeted them with a toot from his airhorn, to which Skipper Highjohn responded with a syncopated blast of his own.
The river made a wide curve and the channel passed between a tall headland and a group of craggy islets. Small mechanical sounds announced the furling of their sail, the boom’s folding, and the withdrawal of the telescoping mast back into its housing. Far from losing speed, the boat moved along faster rounding the point. It seemed to Bryan that they must be making thirty knots or more. Simultaneously he became aware of a deep vibration transmitted by the water through the sealed hull of the boat, the inflated headrest of his seat, and the very bones of his skull. The vibration increased to an audible roar as the boat came charging around a sharp bend. The walls of a canyon rose on both sides.
Sukey screamed and Raimo yelped an obscenity.
Ahead of them the narrowing Rhône slanted downhill at a one-in-five gradient, the river lashed to a foaming frenzy by the rocks of its tilted bed. The boat seemed to dive into the rapids and a great avalanche of ochre water crashed over the canopy and temporarily engulfed them. Then Mojo broke free and came to the surface, planing along among monstrous standing waves and granite boulders, rolling so steeply that yellow water climbed halfway up the watertight bubble first on one side, then on the other. The noise was almost insupportable. Raimo’s mouth was wide open but his yells went unheard amidst the uproar of the cascading Rhône.
A dark mass loomed ahead. The boat heeled nearly sixty degrees to starboard as they went whipping around a tall rock pinnacle into a crooked slot between files of huge boulders. The air was so filled with flying spume that it seemed impossible that their skipper could see where he was going. Nevertheless the boat continued to zig and zag among the rocks with only an occasional bump against the pneumatic fenders.
A respite came in the form of a deep cut where the river flowed free. But the voice of Highjohn called, “One last time, folks!” and Bryan realized that they were rocketing through the defile toward a veritable fence of sharp crags, fanglike chunks of broken granite against which the yellow river waters crashed in overlapping curtains of spray. There seemed to be no way through. The stunned time-travelers gripped the arms of their seats and braced for the inevitable impact.
Mojo raced toward the tallest of the rocks, pitching violently. It crashed into the foam, but instead of hitting solid rock or sinking, it rose higher and higher on some unseen surge. There was a thrumming blow against the port side as they bounced off a rock face, completely drowned in the opaque pother. The boat seemed to roll a full 360 degrees and then wallow free to sail through the air. It landed with a bone-jarring impact, water closing again over the top of the canopy. Almost immediately it popped to the surface, floating in complete tranquility across a broad pool that spread between low walls. Behind them was the cut they had just traversed, spewing a horsetail cataract, like the outflow of a titanic drain, into the basin thirty meters below.
“You can unfasten your safety belts now, folks,” the skipper said. “That’ll be all the cheap thrills for this morning. After lunch, it really gets rough.”
He came back into the passenger compartment to check the canopy for possible leakage. “Didn’t take in a drop!”
“’Congratulations,” whispered Bryan. With one trembling hand be fumbled with the buckles of the harness.
“Give you a hand?” suggested Highjohn, bending over to help.
Released, Bryan rose weakly to his feet. He saw that all the others, including Creyn and Elizabeth, were motionless in their seats, eyes closed, apparently asleep.
Fists on hips, the rivermen surveyed the passengers with a slow shake of his head. “Every goddam time. These sensitive Tanu types just can’t take Cameron’s Sluice, being afraid of water as they mostly are. So they zonk out. And if the torc-wearing humans show any distress, the Tanu just program a zonk for them, too. Kinda disappointing, you know? Every artist likes to have an audience.”
“I take your point,” Bryan said.
“I don’t often get a rarey like you, no torc and all and man enough to come through it without a case of the yammering fantods. This lady without the torc”, he pointed to Elizabeth, “must have just fainted away.”
“Not likely,” Bryan said. “She’s an operant metapsychic. I dare say she just did her own calming mental exercise and napped through the excitement, just as Creyn did.”
“But not you, eh, sport? I suppose you’ve been on rough water before.”
Bryan shrugged. “Hobby sailor. North Sea, Channel, Med. The usual thing.”
Highjohn clapped him on the shoulder. His eyes twinkled and he gave Bryan a comradely smile. “Tell you what. You come on forward with me and I’ll show you a thing or three about driving this tub before we reach Feligompo. If you enjoy it, who knows? There’s lots worse jobs you could settle into in this Exile.”
“I’d enjoy riding with you in the wheelhouse,” Bryan said, “but I won’t be able to take you up on your offer of an apprenticeship.” He grinned ruefully. “I believe the Tanu have other plans for me.”
