Animal engine

An animal engine is a machine powered by an animal. Horses, donkeys, oxen, dogs, and humans have all been used in this way. An unusual example of an animal engine was recorded at Portland, Victoria in 1866. A kangaroo had been tamed and trained to work a treadmill which drove various items of machinery.
