I could tell you many a tale aboutt slippering and boys I had caned in my office, but do not want to go into all the details as I may be accused of taking over this good site.
I revcall one mother about 1955 complaining about two boys who had thrown mud at her washing. She gave me their names. In those days we could deal with offences outside school. I sent for the two boys and they admitted the offence. I told them they each get three strokes on their backsides.
