There are several interesting observations that come from this.
First: The method of punishment. I was once in possession of two punishment books from the Stewart Street School in Birmingham. Those books spanned 1892 to 1943, and again all incidents were for caning, and on the hands only. It would appear that Birmingham was one of the LEAs that adopted hand caning (rather than seat) and that this occurred even prior to the 1900’s. (in case you’re wondering, those have since been returned to the possession of the Birmingham archives)
Second: the frequency of punishment. 50 incidents spanning 19 school years is about 2 1/2 canings per year. This evidences the incredible amount of restraint in deploying CP at this school. I have seen other books (like The Catford Boy’s School, London) where the caning rate averaged 3 per day, not per year!
