Dot and the Kangaroo (version 2) - Ethel C. PEDLEY

A 5-year-old girl named Dot is lost in the outback after chasing a hare into the wood and losing sight of her home. She is approached by a red kangaroo who gives her some berries to eat. Upon eating the berries, Dot is able to understand the language of all animals, and she tells the kangaroo her plight. The kangaroo, who has lost her own joey, decides to help little Dot despite her own fear of humans. The book is filled with criticism on negative human interference in the wild in 1884.
