Roy Rockwood, Bomba the jungle boy (1926)
“ For a moment Bomba was so taken aback by the sight of the jaguar that he did not stir.His harmonica was still between his lips, and the sudden exclamation that was forced from him droned through the mouth organ in a weird, discordant note.The wailing cry had a strange and instant effect upon the beast. It had crouched as though for a spring, but now it hesitated. It had never seen a human with a gleaming mouth like that. It had never heard that kind of sound. The jungle beast is a creature of habit. Anything new is disconcerting. ”
