Once upon a time...
There was a country where the rivers were larger, and the forests deeper, than anywhere else. Hardly any men came there, and the wild creatures had it all to themselves, and used to play all sorts of strange games with each other. The great trees, chained one to the other by thick flowering plants with bright scarlet or yellow blossoms, were famous hiding-places for the monkeys, who could wait unseen, till a puma or an elephant passed by, and then jump on their backs and go for a ride, swinging themselves up by the creepers when they had had enough. Near the rivers huge tortoises were to be found, and though to our eyes a tortoise seems a dull, slow thing, it is wonderful to think how clever they were, and how often they outwitted many of their livelier friends.
