He drudged away at the problem, like a man underwater.

People had used the dial. Touched it. People had repaired it. Installed it. People had dreamed of it before the building, before the installing, before the repairing and touching and using. The dial contained memory of use and manufacture, its very shape was a dream-memory telling Sim why and for what it had been built. Given time, looking at anything, he could draw from it the knowledge he desired. Some dim part of him reached out, dissected the contents of things, analyzed them.

This dial measured time!

Millions of days of time!

But how could that be? Sim's eyes dilated, hot and glittering. Where were humans who needed such an instrument?

Blood thrummed and beat behind his eyes. He closed them.

Panic came to him. The day was passing. I am lying here, he thought, and my life slips away. I cannot move. My youth is passing. How long before I can move?

Through a kind of porthole he saw the night pass, the day come, the day pass, and again another night. Stars danced frostily.

I will lie here for four or five days, wrinkling and withering, he thought. This ship will not let me move. How much better if I had stayed in my home cliff, lived, enjoyed this short life. What good has it done to come here? I'm missing all the twilights and dawns. I'll never touch Lyte, though she's here at my side.

Delirium. His mind floated up. His thoughts whirled through the metal ship. He smelled the razor sharp smell of joined metal. He heard the hull contract with night, relax with day.
