They intended, later, to get into their pajamas.
A single lantern, its wick turned low, hung from one of the posts.
Prescott did not trust himself to lie down, for his eyes, despite his efforts to keep awake, were heavy, and he did not want to sleep for some time yet.
Within ten minutes Darrin alone had his eyes open, and even he was making a valiant struggle against sleep.

At last, however, he yielded, and soon settled into sound slumber.
"They're off in another world," smiled Dick, as he listened to the deep breathing of his chums; then he slipped away from his cot.
From under a box in one corner of the tent he took out a large cup of coffee that he had hidden some time earlier.

It was still warm and he drank it with relish, though his main purpose in using the beverage was to make sure of keeping himself awake.
His next move was to extinguish the lantern.

Now he made his way to the bucket of water and basin.

Dashing the cold water into his face, and wetting his eyes well with it, Prescott took a few deep breaths.
