A series of men sit with their heads fixed, waiting to have their beards automatically trimmed by a machine, which is mounted on a track. The text gives an explanation of the proces. The boy in the foreground is dresing a wig in 'the ordinary and tedious manner'. The machine was supposedly sold by D Merry and Son of Birmingham at a cost of seven guineas.
