It seems that this teacher was very fond of smacking both boys and girls.
The trouble is that I doubt if at that time he was breaking any laws provided it was smacking and not fondling children’s bottoms.
Indeed, even if he was doing it bare I doubt if he was breaking the law.
Education Authorities and School Boards had rules on who could use corporal punishment and how it was used.
In most cases, it was only for the cane and excluded the use of slippers and hands.
