Quotation from: The Beasts of Tarzan

Written by: Edgar Rice Burroughs

The great tree with its entangling branches rose gradually from
the panther, who, feeling the encumbering weight diminish, quickly
crawled from beneath. Tarzan let the tree fall back to earth, and
the two beasts turned to look upon one another.

A grim smile lay upon the ape-man's lips, for he knew that he had
taken his life in his hands to free this savage jungle fellow; nor
would it have surprised him had the cat sprung upon him the instant
that it had been released.
