He remembered now that he had wanted to sleep.

He recalled the cliff and Waterfall again, and then recollected something about talking to a passer-by....
How long had he slept?
What was that sound of pattering feet?
And that rise and fall, like the murmur of breakers on pebbles?
He put out a languid hand to reach his watch from the chair whereon it was his habit to place it, and touched some smooth hard surface like glass.

This was so unexpected that it startled him extremely.

Quite suddenly he rolled over, stared for a moment, and struggled into a sitting position.

The effort was unexpectedly difficult, and it left him giddy and weak--and amazed.
He rubbed his eyes.
