the proper time to harvest them. There were so many things,
things that none of those young savages or their children would think of
in ten thousand years....

Something was moving among the rocks, a hundred yards away. He
straightened, as much as his broken legs would permit, and watched. Yes,
there was one of them, and there was another, and another. One rose from
behind a rock and came forward at a shambling run, making bestial
sounds. Then two more lumbered into sight, and in a moment the ravine
was alive with them. They were almost upon him when Kalvar Dard pressed
in the thumbpiece of the bomb; they were clutching at him when he
released it. He felt a slight jar....

When they reached the pass, they all stopped as the son of Kalvar Dard
turned and looked back. Dorita stood beside him, looking toward the
waterfall too; she also knew what was about to happen. The others merely
gaped in blank incomprehension, or grasped their weapons, thinking that
the enemy was pressing close behind and that they were making a stand

Then a tiny pin-point of brilliance winked, just below where the

"What do you mean?" The boy was puzzled, not knowing how much he looked
like his father, when his father had been an officer of the Frontier
Guards, twenty years before.

His puzzlement worried Varnis vaguely. "You.... You are Dard, aren't
you?" she asked. "But that's silly; of course you're Dard! Who else
could you be?"

"Yes. I am Dard," the boy said, remembering that it was the rule for
everybody to be kind to Varnis and to pretend to agree with her. Then
another thought struck him. His shoulders straightened. "Yes. I am Dard,
son of Dard," he told them all. "I lead, now. Does anybody say no?"

He shifted his axe and spear to his left hand and laid his right
