How does George MacBeth use imagery in Bedtime Story?

We do not know the time to which the narrator refers, but the Congo itself, today as in the past, evokes an image of lushness and wild primates, of untamed nature. The country is known for its game reserves and national parks sheltering animals, such as lions, monkeys, gorillas, zebras, antelope, elephants, and other rare animals like the Bonobo apes and the Okapi antelopes. But it is not the actual Congo to which the speaker refers. It is a Congo of the imagination which draws on our image of the real Congo.
