A great swell of Riverwater lifted the ship high. Clemens opened his eyes and then screamed but could not hear his own voice because of his stunned ears.

A wall of dirty brown water, at least fifty feet high, was racing around the curve of the valley between four and five miles away. He wanted to close his eyes again but could not. He continued to gaze with his lids rigid until the elevated sea was a mile away. Then he could make out the individual trees, the giant pines, oaks, and yews scattered along the front of the wave, and, as it got closer, pieces of bamboo and pine houses, a roof somehow still intact, a shattered hull with a half mast, the sperm-whale-sized, dark-gray body of a Riverdragon fish, plucked from the five-hundred-feet depths of The River.

Terror numbed him. He wanted to die to escape this particular death. But he could not, and so he watched with frozen eyes and congealed mind as the ship, instead of being drowned and smashed beneath hundreds of thousands of gallons of water, rose up and up and up on the slope of the wave, up and up, the dirty brown wreckagestrewn cliff towering above, always threatening to avalanche down upon the ship, and the sky above, now turned from bright noon-blue to gray.

Then they were on the top, poised for a downward slide, rocked, dipped, and went down toward the trough. Smaller, but still huge waves fell over the boat. A body landed on the deck near Clemens, a body catapulted from the raging waters. Clemens stared at it with only a spark of comprehension. He was too iced with terror to feel anymore; he had reached the limits.

And so he stared at Livy's body, smashed on one side but untouched on the other side! It was Livy, his wife, whom he had seen on that Riverbank.

Another wave that almost tore nun and the titanthrop loose struck the deck. The helmsman screamed as he lost his grip and followed the woman's corpse overboard.

The boat, sliding upward from the depths of the trough, turned to present its broadside to the wave. But the boat continued to soar upward, though it tilted so that Miller and Clemens were hanging from the stump of the wheel's base as if they were dangling from a tree trunk on the face of a mountain. Then the boat rolled back to horizontal position as it raced down the next valley. Bloodaxe had lost his grip and was shot across the deck and would have gone over the other side if the ship had not righted itself in time. Now he clung to the port railing. On top of the third wave, the Dreyrugr sped slantwise own the mountain of water. It struck the broken forepart of another vessel, shuddered, and Bloodaxe's grip was torn loose by the impact. He spun along the railing, hit the other railing on the edge of the poopdeck, shattered it, and went on over the edge and below to the middeck.

Not until morning of the next day did Sam Clemens thaw out of his shock. The Dreyrugr had somehow ridden out the great waves long enough to go slanting across the plains on the shallower but still rough waters. It had been shot past hills and through a narrow pass into a small canyon at the base of the mountain. And, as the waters subsided from beneath it, the boat had settled with a crash into the ground.

The crew lay in terror thick as cold mud while The River and the wind raged and the sky remained the color of chilling iron. Then the winds ceased. Rather, the downRiver winds stopped, and the normal soothing wind from upRiver resumed.

The five survivors on deck began to stir and to ask questions. Sam felt as if he could barely force the words out through a numbed mouth. Stammering, he told them of the flash he had seen in the sky fifteen minutes before the winds struck. Somewhere down the valley, maybe two hundred miles away, a giant meteorite had struck. The winds created by the heat of passage through the air and by the displacement of air by the meteorite had generated those giant waves. Terrible as they were, they must have been pygmies compared to those nearer the point of impact. Actually, the Dreyrugr was in the outer edge of the fury.

"It had quit being mad and was getting downright jovial when we met it," Sam said.

Some of the Norse got unsteadily to their feet and tottered across the deck. Some stuck their heads out of the hatches. Bloodaxe was hurting from his roll across the deck, but he managed to roar, "Everybody belowdecks! There will be many more great waves much worse than this one, there's no telling how many!"

Sam did not like Bloodaxe, to put it mildly, yet he had to admit that the Norwegian was bright enough when it came to the ways of water. He himself had supposed that the first waves would be the last.

The crew lay down in the hold wherever they could find space and something stable to hang onto, and they waited, but not for long. The earth rumbled and shook, and then The River struck the pass with a hiss like a fifty-foot-high cat, followed by a bellow. Borne upward by the flood pouring through the pass, the Dreyrugr rocked and spun around and around as it rocked. Sam turned cold. He was sure that if there had been daylight, he and the others would look as grayblue as corpses.

Up the boat went, occasionally scraping against the Walls of the canyon. Just as Sam was about to swear that the Dreyrugr had reached the top of the canyon and was going to be carried over its front in a cataract, the boat dropped. It sank swiftly, or so it seemed, while the waters poured out through the pass almost as quickly as they had entered. There was a crash, followed by the heavy breathing of men and women, a groan here and there, the dripping of water, and the far-away roar of the receding river.

It was not over yet. There was more waiting in cold numb terror until the great mass of water would rush back to fill the spaces from which it had been displaced by the blazing many hundreds of thousands of tons mass of the meteorite. They shivered as if encased in ice, although the air was far warmer than it had even been at this time of night. And, for the first time in the twenty years on this planet, it did not rain at night.

Before the waters struck again, they felt the shake and grumble of earth. There was a vast hiss and a roar, and again the boat rose up, spun, bumped against the walls of the canyon and then sank. This time, the ship did not strike the ground so hard, probably, Sam thought, because the boat had hit a thick layer of mud. "I don't believe in miracles," Sam whispered, "but this is one. We've no business being alive."

Joe Miller, who had recovered more swiftly than the rest, went out on a half-hour scouting trip. He returned with the naked body of a man. His burden was, however, alive. He had blond hair under the mud-streaks, a handsome face and blue-gray eyes. He said something in German to Clemens and then managed to smile after he had been deposited gently on the deck.

"I found him in hith glider," Joe said. "Vhat vath left of it, that ith. There'th a number of corptheth outthide thith canyon. Vhat you vant to do vith him?"

"Make friends with him," Clemens croaked. "His people are gone; this area is cleaned out."

He shuddered. The image of Livy's body placed on the deck like a mocking gift, the wet hair plastered over one side of her smashed face, the one dark eye staring darkly at him, was getting more vivid and more painful. He felt like sobbing but could not and was glad of it. Weeping would make him fall apart into a cone of ashes. Later, when he had the strength to stand it, he would weep. So near. ...

The blond man sat up on the deck. He shivered uncontrollably and said, in British English, "I'm cold."

Miller went belowdecks and brought up dried fish, acorn bread, bamboo tips and cheese. The Vikings had stored food to eat when they were in hostile areas where they were forbidden to use their grails.
