Edgar Rice Burroughs,
Return of Tarzan
(1913)
“ Every sense was on the alert as with crafty stealth he moved quickly through the trees, up-wind, in the direction of his prey. Presently he came upon it—a lone warrior treading softly through the jungle. Tarzan followed close above his quarry, waiting for a clearer space in which to hurl his rope. As he stalked the unconscious man, new thoughts presented themselves to the ape-man—thoughts born of the refining influences of civilization, and of its cruelties. It came to him that seldom if ever did civilized man kill a fellow being without some pretext, however slight. ”
