Dard sat very still, afraid to answer, afraid to burst out with the wild exultation which surged in him now. He had tried, tried so hard these past few days to follow Harmon’s overpowering interest in the land, to be another, if unskilled, pair of hands in the work about the cave. But the machines they were assembling at top speed were totally unknown to him. The men who worked on them lapsed into a jargon of functions he knew nothing about, until it seemed that they jabbered a foreign tongue.

For so long he had been responsible for others-for Lars and Dessie, for their food, their shelter, even their safety. And now he was not even responsible for himself. He was beginning to feel useless, for here he knew so little that was of any account.

All his training had been slanted toward keeping alive, at a minimum level of existence, in a hostile world. With that pressure removed he believed he had nothing to offer the colonists.

What he had dreamed and longed to do was to leave this compact group where he was the outsider, to go on into this new world, searching out its wonders, whether that meant trailing a hopper to its mysterious lair or flying above the cliffs into the unknown country beyond. Exploration was what he wanted, wanted so badly that sometimes just thinking about it hurt.

And here was Kimber offering him that very thing! Dard could not say anything. But maybe his eyes, his rapturous face answered for him, as the pilot glanced up, met Dard’s wide happy eyes; and quickly looked away. Then the boy’s feelings were under control again, and he was able to say, in what he believed was a level and unmoved voice:

“But what are you planning?”

“Go up and over.” It was Cully who answered that before Kimber could swallow his mouthful of stew. “We load up this old bus,” the engineer patted the sled affectionately, “and take off to see what lies on the other side of the cliffs. Mainly to discover whether we need expect any visitors.”

“We- who?”

Kimber named those who would share in the adventure.

“I’ll pilot. Cully goes along to keep the sled ticking. And Santee is to provide the strong right arm.”
