Late in September the boats reappeared on the river, and the people gathered at the dock to watch. It was a cold, rainy day; already frosts had turned the landscape bleak, and fog over the river obscured everything until the boats were very close. A meeting party set out to help bring in the exhausted people, and when they were all docked and the tally taken, the realization that nine people had been lost wreathed the homecoming in gloom.

The following night they held the Ceremony for the Lost, and the survivors told their story haltingly. They had brought back five boats, one under tow most of the way. One boat had been swept away at the mouth of the Shenandoah; they had found it smashed and broken up, with no survivors, its load of surgical equipment lost to the river. The second damaged boat had been run aground by a sudden storm that overturned it and ruined its load of maps, directories, warehouse lists—bales and bales of papers that would have proven useful.

The shelter at the falls had been started; the canal had proven disastrous, impossible to dig as proposed. The river flooded in from below and washed it out repeatedly, and all they had succeeded in doing was to make a swampy area that flooded in high water and was a muddy bog when the river fell. And the worst part, they agreed, had been the cold. As soon as they had reached the Potomac the cold had plagued them. There had been frosts; leaves had fallen prematurely, and the river was numbing. Much of the vegetation was dead; only the hardiest plants were surviving. The cold had persisted in Washington, had made the canal digging a hellish task.

The snow came to the valley early that year, on the first of October. It remained on the ground for a week before the wind shifted and warm southerly breezes melted it. On the infrequent clear days when the sun shone brightly and no mist hid the tops of the surrounding hills and mountains, the snow could still be seen on the high ridges.

Later Barry would be able to look back on that winter and know it had been crucial, but at the time it seemed just one more in the endless string of seasons.

One day Bob called to him to come outside and look at something. No new snow had fallen for several days, and the sun was bright and gave the illusion of warmth. Barry pulled on a heavy cape and followed Bob out. There was a snow sculpture standing in the center of the courtyard between the new dorms. It was a male figure, eight feet tall, nude, its legs fused into a base that was also a pedestal. In one hand the figure carried a club, or perhaps a torch, and the other hand swung at its side. The feeling of motion, of life, had been captured. It was a man on his way to somewhere else, striding along, not to be stopped.

“Mark?” Barry asked.

“Who else?”

Barry approached it slowly; there were others looking at it also, mostly children. A few adults were there, and others came out until there was a crowd about the statue. A small girl stared, then turned and began to roll a snowball. She threw it at the figure. Barry caught her arm before she could throw again.

“Don’t do that,” he said.

She looked at him blankly, looking at the figure even more blankly, and started to inch away. He released her, and she darted back through the people. Her sisters ran to her. They touched each other as if to reassure themselves that all was well.

“What is it?” one of them asked, unable to see over the heads of the people between her and the statue.

“Just snow,” the little girl answered. “It’s just snow.”

Barry stared at her. She was about seven, he thought. He caught her again, and this time lifted her so she could see. “Tell me what that is,” he said.

She wriggled to get loose. “Snow,” she said. “It’s snow.”

“It’s a man,” he said sharply.

She looked at him in bewilderment and glanced at the figure again. Then she shook her head. One by one he held other small children up to see. All they saw was snow.

Barry and his brothers talked to their younger brothers about it later that day, and the younger doctors were impatient at what was clearly, to them, a trifle.

“So the younger children can’t see that it’s supposed to be the figure of a man. What does it matter?” Andrew asked.

“I don’t know,” Barry said slowly. And he didn’t know why it was important, only that it was.

During the afternoon the sun melted the snow a bit, and overnight it froze solid once more. By morning when the sun hit the statue, it was blinding. Barry went out to look at it several times that day. That night someone, or a group, went out and toppled it and stamped it into the ground.

Two days later four groups of boys reported the disappearance of their mats. They searched Mark’s room, other places where he might have hidden them, and came up with nothing. Mark started a new sculpture, this time a woman, presumably a companion piece to the man, and this time the statue remained until spring, long after it was no longer identifiable, but was simply a mound of snow that had melted, frozen, melted repeatedly.

The next incident happened soon after the New Year celebration. Barry was awakened from a deep sleep by an insistent hand on his shoulder.

He sat up feeling groggy and disoriented, as if he had been pulled a long way to find himself in his bed, cold, stupid, blinking without recognition at the younger man standing over him.

“Barry, snap out of it! Wake up!” Anthony’s voice registered first, then his face. The other brothers were waking up now.

“What’s wrong?” Suddenly Barry was thoroughly awake.

“A breakdown in the computer section. We need you.” Stephen and Stuart were already tearing down the computer when Barry and his brothers got to the laboratory. Several younger brothers were busy disconnecting tubes from the terminal in order to regulate the flow manually. Other young doctors were making a tank-by-tank check of the dials. The scene was of orderly chaos, Barry thought, if there could be such a thing. A dozen people were moving about quickly, each intent on his own job, but each out of place there. The aisles became cluttered when more than two people tried to move among the tanks, and now there were a dozen, and more coming every minute.

Andrew had taken charge, Barry noted with satisfaction. All the newcomers were assigned sections immediately, and he found himself monitoring a row of embryos seven weeks old. There were ninety babies in the tanks at various stages of development. Two groups could be removed and finished in the premature ward, but their chances of survival would be drastically reduced. His group seemed all right, but he could hear Bruce muttering at the other end of the same aisle and he knew there was trouble there. The potassium salts had been increased. The embryos had been poisoned.

The scientists were spoiled, he thought. So used to the computer analysis of the amniotic fluids, they had let their own skills deteriorate. Now trial and error was too slow to save the embryos. The survivor of that group was turned off. No more solitaires. Members of another group had suffered, but this time only four were overdosed. The six survivors were allowed to continue.

Throughout the night they monitored the fluids, added salts as they were needed, diluted the fluids if salt started to build, kept a temperature check and oxygen count, and by dawn Barry felt as if he were swimming through an ocean of congealed amniotic fluids himself. The computer was not yet functioning. The checks would have to be continued around the clock.

The crisis lasted four days, and during that time they lost thirty-four babies, and forty-nine animals. When Barry finally fell into bed exhausted, he knew the loss of the animals was the more grievous. They had depended on those animals for the glandular secretions, for the chemicals they extracted from their bone marrow and blood. Later, he thought, sinking down into the fog of sleep, later he would worry about the implications of the loss.

“No maybes! We have to have the computer parts as soon as the snow melts. If this happens again, I don’t know if we can repair it.” Everett was a thin, tall computer expert, no more than twenty, possibly not that yet. His older brothers deferred to him, and that was a good sign that he knew what he was talking about.

“The new paddle-wheel boats will be ready by summer,” Lawrence said. “If a road crew can get out early enough to make certain the bypass is open . . .”

Barry stopped listening. It was snowing again. Large lazy flakes of snow drifted, i............
