A kind of chair formerly used for punishing scolds, and also
dishonest tradesmen, by fastening them in it, usually in
front of their doors, to be pelted and hooted at by the mob,
but sometimes to be taken to the water and ducked; -- called
also a {castigatory}, a {tumbrel}, and a {trebuchet}; and
often, but not so correctly, a {ducking stool}. --Sir. W.
Scott.
