A "bullish" economy|
Bison were a staple of the economy in the 1800s. As Americans became more industrial, the need for machine belts made from hides grew and grew. Sport-hunting also became the rage. Railroad companies offered tourists a chance to shoot bison from the coaches; one record-setting rider killed as many as 120 animals in 40 minutes. Within 50 years, the great herds were gone.
