At our place, lines were from praefects only, so I’ll leave them out.
Masters never caned, only the Head, Deputy Head or Head of The Lower School(years 1 & 2). Few masters slippered, never heard of it beyond the 2nd year.
Detentions were initially on Saturday mornings, 1 or 2 hours. So you had to don school uniform etc & ride into town. You did extra schoolwork set by the master that gave you the detention, regardless of whether whether it was for poor work or misbehaviour
This was split by Moody into Returned Work(after school Tues & Weds) & Punitive Detentions(after school Thursdays) for slackers & trouble-makers respectively. RWD remained as schoolwork, punitive became polishing brass door handles or cleaning up school fields, rifle range etc.
The only other one was the school-field-circuit-in-dinner-hour from the Head of PE & Rugby, Tish Stewart, for those caught smoking/shortcutting on cross-country afternoons in games.
So
1) Cane
2) Saturday Detention
3) Slipper
4) School Field Circuits
5) Punitive Detention
6) Returned Work Detention
None was any deterrent-I never considered myself anti-social, letting the school down or buggering it up for others, and still don’t.
