In about the 15th century, however, with the advent of the sawmill, the old log troughs began to be replaced by hives made of boards. These were humorously referred to as truge, or coffins, because of their oblong shape.
15. sajandil, kui leiutati saeveski, hakati aga kasutama laudadest tehtud tarusid, mida nende pikliku kuju tõttu kutsuti naljatades puusärkideks (truge).
