Cattle
Oxen must be trained from a young age. The owner must make or buy as many as a dozen yokes of different sizes as the animals grow. Ox teams are steered by shouted commands, whistles or the noise of a whip crack. Men who drove ox teams were called teamsters in America, wagoners in Britain, or in Australia, bullockies. Many bullockies and teamsters were famous for their voices and for their foul language.
