No, Sir. The call-up of such men will be deferred so long as they remain satisfactorily employed in underground work in the coalmines, but if they leave that employment before reaching the age of 26 they will be regarded as available for call up. I would like to emphasize that the object of the decision to defer young men going into coalmining is to encourage young men to enter coalmining permanently. The industry does not want men for a period of two years or 18 months only.
