Umboo, The Elephant by Howard R. Garis

Have you ever wondered what it is like to be in a circus? What if, rather than choosing to be in one, you were captured and taken away from the home and family you knew and made to perform in the heat of a big top? Meet Umboo, the elephant, Chako, the monkey, Snarlie, the tiger and their circus friends and learn how life in the jungle was different from life in the circus.
