Once upon a time, the law required that a person enter a plea before they could be tried (they hadn't yet developed the concept of the court entering a plea on your behalf if you refused to do so yourself). This provided an opportunity for the accused to escape justice by avoiding trial.
In France, the response to this was "Peine forte et dure", in which the accused would be laid down with a board placed upon them, and heavier and heavier weights placed until they either capitulated and entered a plea, or died. In English law it became known as "pressing". It seems that our current use of the term "press", as in "press for information", stems from this practice of gradually applying pressure until the person finds it intolerable and provides an answer.
This method was used exactly once by an authoritative body in American history. One of the accused in the Salem Witch Trials, Giles Corey, was pressed to death for refusing to enter a plea. Contrary to popular legend, the rest were all hung - none were burned to death.
Giles Corey was pressed over the course of twodays, at the age of 81. Each time he was asked to enter a plea, he responded with "more weight". Eventually his tongue began protruding from his mouth and the sheriff would use a cane to shove it back in.
When he eventually died, he did so in full possession of his estate, which would have been forfeited had he been convicted.
