I feel fine, everything is fine. I check the instruments ...

Go back....

There was no lessening.

Colin's shirt was slick on his body with sweat, his face looked old, older, his breath came in almost imperceptible quaverings, but his voice remained calm and assured, in violent and distinct contrast to the strain that showed plainly as age in his face—

Move ahead....

Move back....

Twenty-three minutes later, Colin closed his eyes and said:

In ten minutes from this time you will waken feeling refreshed and relaxed, as after a good sleep. You will be alert and fresh when you waken. You will feel as if you have just had a pleasant nap. You will remember nothing of what has happened while you were asleep, but you will feel fresh and relaxed when you waken ten minutes from this time.

He finished the waking-formula mechanically and left the little room. He walked slowly and deliberately to his quarters on the base, as though holding himself rigidly in control. He did not answer Banning's excited questions except to say, "I can't talk about it now."

Reaching his room he fell full length on the bed and was asleep nearly before the swaying of the bed had quieted.
