Quotation from: The Valley of the Moon

Written by: Jack London

In vain Saxon tried to win sleep. The sand grew harder with the
passage of time. Her flesh and her bones ached from contact with
it. And, though her reason flouted any possibility of wild
dangers, her fancy went on picturing them with unflagging zeal.

A new sound commenced. It was neither a rustling nor a rattling,
and it tokened some large body passing through the brush.
Sometimes twigs crackled and broke, and, once, they heard
bush-branches press aside and spring back into place.
