The assurance given in paragraph 4 of Circular 119 has been implemented by the passing of the National Service (Armed Forces) Act, 1939, the Education (Scotland) (War Service Superannuation) Act, 1939, and the Local Government Staffs (War Service) Act, 1939. By the last of these Acts, education authorities are empowered to make up the balance of the civil pay of-teachers who undertake war service, but I am informed that there is considerable diversity of practice between different authorities both in Scotland and in England and Wales.
