(1913)
“ What next?""Stop playing the fool, General Captain!" commanded the pithecanthrope, in a rough, animal voice, employing animal sounds that produced an immediate effect.General Captain ceased pretending to be a man and, from his perch on a branch so high that none of us could have seen it from below, even had it been daylight and even had we had Balaoo's eyes, he humbly bade his master welcome, like the humble porter-parrot that he was and in the parrot tongue, which Balaoo understood quite well, for almost all animals understand one another's language. ”
