Spittoon
A spittoon was a receptacle for persons to deposit their saliva into, typically while chewing tobacco. They were located on the floor or ground for this purpose.
Such objects were, among Humans, associated with the Ancient West. While on a failed Skagaran colony, Commander Charles Tucker noted that a Human settlement there was an authentic recreation of a settlement from that period of time, down to the spittoons. (ENT: "North Star")
