Generally, the caning took place in the form-masters’ studies, and required the boy to take down his trousers and underpants, then to bend over a chair or desk or similar thing.
My Uncle stated that some masters would not always cane bare bottom, or cane particularly hard.
Others,on the other hand, caned very hard indeed and raised welts on the boys’ bottoms that lasted for some days.
The caned bottoms were a subject of conversation in the showers and were seen as a badge of honor in some ways.
