In his room, Ken dressed impatiently. It was useless to try to sleep any more. "I wish they'd let us go out there," he said. "We've got as much right as Johnson or any of the rest."
His father remained a motionless silhouette against the distant firelight. "As much right, perhaps," he said, "but more and different responsibilities. Hilliard is right. If we were knocked down out there who would take over the work in the laboratory? Johnson? Adams?
"In Berkeley there are thousands fighting each other, but with French and his group gone, no one is fighting the comet. I don't think it is selfish to say we are of infinitely more value in the laboratory than we could ever be out there with guns in our hands."
He turned and smiled in the half-darkness. "That's in spite of the fact that you have the merit badge for marksmanship and won the hunting club trophy last year."
After an hour the attack ceased, apparently because the defenders refused to waste their fire on the impossible targets. Sheriff Johnson sent word around for his men to resume rotation of watch and get all the sleep possible before the day that was ahead of them.
The fires burned themselves out shortly before dawn. Their light was followed soon by the glow of the comet rising in the southeast. Ken watched it and thought of Granny Wicks. It wouldn't be hard, he thought, to understand how a belief in omens could arise. It wouldn't be hard at all.
The sky had cleared so that the light of the comet bathed the entire countryside in its full, bitter glory. At sunrise the faint trickles of smoke rose from hundreds of wood fires, started with the difficult green fuel, and stringent breakfasts were prepared. A thought went through Ken's mind and he wondered if anybody was taking note of the supply of matches in town. When they ran low, coals of one fire would have to be kept to light another.
It was 9 o'clock, on a day when ordinarily school bells would have been sounding throughout the valley. The first war shouts of the attacking nomads were heard on the plain to the south. About thirty men on horseback raced single file along the highway that bore the hard, frozen tracks of horses and sleds that had moved to and from the farms down there.
Patrolman Sykes watched them through his glasses. His command rang out to his company. "Hold fire." He knew the nomads would not hope to break through the barbed wire on such a rush. It looked as if they planned an Indian-style attack as the line began breaking in a slow curve something less than 100 yards away.
"Fire!" Sykes commanded. Volleys of shots rang out on both sides almost simultaneously. The lead rider of the nomads went down, his horse galloping in riderless panic at the head of the line. The hard-riding column paralleled the barrier for 200 yards, drawing the fire of adjacent guard posts before they broke and turned south again. It was, evidently, a test of the strength of the defenses.
